## Abstract

Aiming at the problems of long retrieval time of sports tourism data, high integration error of sports tourism data, and high energy consumption of sports tourism service management in traditional methods, the application of Internet of Things and edge computing technology in sports tourism services is proposed. We established a sports tourism service application model based on Internet technology to realize the functions of sports tourism service internal management control, external collaboration, and information release. We calculated the similarity of sports tourism resources from the two levels of feature words and the environment where the sports tourism resources are located. According to the calculation results, the edge computing method is used to realize the integration of sports tourism service resources to improve the application effect of sports tourism service application models. The experimental results show that the minimum data retrieval time of the proposed method is only 2.35s. The sports tourism data fusion error is low. The management energy consumption is small, which significantly improves the existing problems and fully verifies the practical application value of the method.

## Body

## 1. Introduction

The Internet of Things is another major change in the development of science and technology after computers, the Internet, and mobile communication networks. It combines virtual information and reality to make some behaviors and activities in real life intelligent efficient and convenient. Therefore, when the era of the Internet of Things is approaching, the development of sports tourism services should seize the opportunity of innovation in the application of Internet of Things technology, accelerate the process of upgrading informatization and intelligence, and achieve leapfrog development [1]. Through the collection of related literature, such as books, literature, network, television, and paper media, although the relevant knowledge about the application of Internet technology in sports tourism services is not extensive, it can be seen that the technology is getting more and more attention. Although the content level of research related knowledge is uneven, the common point of all research content is to realize the efficient integration, sharing, and application of sports tourism service resources and data, so as to achieve the improvement of sports tourism service quality [2].At present, scholars at home and abroad have conducted in-depth research on the application of Internet technology in sports tourism service. Pauline Sheldon has earlier and more comprehensively discussed the application of information system technology in the electronic market and how to combine the supply and demand of tourism. Professor Hannes Wertlmer from the University of Vienna in Austria and Stefan Klein from the University of Münster in Germany explained that sports tourism is essentially an information-intensive industry, pointed out that the information industry will challenge the traditional sports tourism industry, and discussed the information industry. The future ultimately will have a huge impact on the behavioral organization structure of the sports tourism industry, government management methods, and commercial transactions [3–5]. Compared with the theoretical system of sports tourism informatization research in foreign developed countries, although the domestic theoretical system is not mature enough, certain achievements have been made. Reference [6] puts forward a method of intelligent tourism spatiotemporal database resource integration based on SVM, which uses three-dimensional laser scanning technology, three-dimensional panoramic photography technology, and GPS technology to collect tourism spatial data, respectively, and implements format conversion, unification of data coordinate system, geographic coding, elimination of data acquisition error, and accuracy test on the collected data, so as to complete the integration collection and processing of tourism spatial data. Combining tourism historical time data and collected and processed spatial data, a preliminary integration system of tourism spatiotemporal database resources is constructed based on the six major elements of tourism, and a quantitative expression of the ideal database resource integration scheme is given based on the established system. This article introduces the theory of support vector machines, sets up training data samples, and gives an integrated plan to solve the optimization of tourism resources. The problem is transformed into a quadratic programming problem by Lagrange function, and the optimal integration scheme of smart tourism time-space database resources is obtained by combining the transformation results with the quantitative results of integration scheme. The experimental results show that the resource utilization rate after the integration of this method is high, and the rationality is strong. Reference [7] studies the application of big data in smart tourism management and uses Internet of Things, cloud computing, intelligent data mining, and other technologies in tourism industry development and service management to highly integrate and develop tourism resources and information resources in depth. The example verification shows that this method can realize the high development of tourism resources.Nowadays, with the rapid development of computer and network technology, most human activities are closely connected with the Internet. With the development of large-scale projects such as Digital Earth and Smart City, Smart Tourism has emerged in this context. In order to realize intelligent tourism, the key is to organize and manage the spatiotemporal data of smart tourism scientifically and effectively. Therefore, the construction and design of spatiotemporal database of smart tourism is the core content of the realization of smart tourism. This involves the problem of sports tourism data retrieval and the problem of data error in the Internet of Things. In addition, we also need to consider the security and communication issues involved.Although the existing methods have achieved remarkable results in practical applications, from the current application status of the Internet of Things in sports tourism services, several problems can be analyzed. (1) In the sports tourism service of the Internet of Things, there is a problem of long retrieval time of sports tourism data and poor real-time performance. (2) The coordination and integration of the Internet of Things and related functional departments of sports tourism services is insufficient, and some data have errors. (3) The Internet of Things technology consumes huge energy in sports tourism service management. In addition, although related researchers have conducted research on the edge computing of the Internet of Things, they only designed the corresponding fuzzy system and did not conduct in-depth research on the integration of sports tourism resources. Aiming at the problems of existing methods, the Internet of Things technology and edge computing technology are combined to study the application effects of the two in sports tourism services.Our contribution is threefold.(1)
Considering the shortcomings of traditional methods, this paper proposes an application model of sports tourism service based on Internet of Things Technology, which integrates the Internet of Things and Edge Computing Technology to realize the internal management control, external collaboration, and information release of sports tourism service.(2)
From the perspectives of feature words and the environment of sports tourism resources, this paper uses edge computing method to realize the integration of sports tourism service resources and improve the application effects of sports tourism service application model.(3)
The experimental results show that the proposed method significantly solves the existing problems in sports tourism data and fully verifies the practical application value of the method.The remainder of this paper is organized as follows. Section2 introduces the application of Internet of things and edge computing technology in sports tourism services. Section 3 discusses experiment and analysis. Section 4 presents the conclusions of the study.


## 2. Application of Internet of Things and Edge Computing Technology in Sports Tourism Services

### 2.1. The Development of Sports Tourism Industry and Establishment of Informatized Tourism Websites

#### 2.1.1. Development of Sports Tourism Service Industry

Sports-related industries have brought great benefits to the social economy. Although, in recent years, the sports tourism service industry is growing stronger and stronger, there are still some deficiencies in driving the economic benefits. In 2019, the ratio of the economic benefits driven by the domestic sports tourism service industry to the total national economic output value is low, which has not reached the global average level, compared with the developed countries There is a big gap [8], as shown in Figure 1.Figure 1
The economic benefits of the sports tourism industry as a percentage of GDP in 2019.According to Figure1, it can be seen that the proportion of economic benefits generated by the current sports tourism service industry is far lower than the world average, which is far behind the developed countries. Therefore, the sports tourism service industry needs further development to constantly improve its economic benefits. Relying on the Internet and other technologies can strongly support and help the long-term development of the sports tourism service industryAlthough the proportion of the sports tourism service industry in the gross national product is not high, it has also shown a continuous growth trend in recent years, which is directly related to the increase in the importance of the related departments to the sports tourism service industry in recent years [9]. The added value of the sports industry from 2011 to 2020 is selected for analysis, and the specific trend chart is shown in Figure 2.Figure 2
Trends in the added value of the sports tourism service industry from 2011 to 2020.According to Figure2, it can be found that the added value of sports tourism service industry has shown a rapid upward trend since 2011, which also shows that, in recent years, the relevant departments have paid more attention to the sports tourism service industry and began to support the development of sports tourism service industry.


#### 2.1.2. Establishment of Information-Based Tourism Website

With the development of the Internet age, tourism-related industries have built network platforms and links to popular APP software platforms in recent years. Relevant resource information has been obtained from specialized network platforms and related APP software platforms, which has increased the number of tourists and increased income. However, the website and information of relevant tourism companies on the Internet are not yet abundant, and it is difficult to meet the individual needs of consumers [10, 11]. Compared with the state of increasing added value of the sports tourism service industry, the information construction of the sports tourism service industry is relatively lagging. The specific situation is shown in Table 1.Table 1

Therefore, with the help of the convenience of the Internet, sports tourism service industry should be combined with the new mode of Internet development to promote the economic development of sports tourism service industry and promote the overall economic growth.


### 2.2. Construction of Internet-Based Sports Tourism Service Application Model

According to the analysis in Section2.1, there are certain shortcomings in the development of the sports tourism industry and the establishment of information-based tourism websites. Therefore, a sports tourism service application model is established based on the Internet of Things. Network information is a key factor in the success or failure of the construction of sports tourism service models. In order to gain a competitive advantage, it is necessary to improve the response ability of sports tourism information, because when tourists decide to travel, before traveling, they always try to obtain various sports tourism information. The Internet now allows people to obtain a variety of information and people rely on it for the channels of obtaining information, forming an Internet-based query method [12, 13]. The information can include the natural and cultural environment, tourism resources, tourism facilities, and services of tourist destinations. The schematic diagram of the sports tourism function system is shown in Figure 3.Figure 3
Schematic diagram of sports tourism function system.The key to measuring the success of sports tourism services is to find the difficulty level of information acquisition of tourist destinations and tourist facilities, which is also an important factor of tourist satisfaction [14]. Therefore, information consultation is actually very important to the development of the tourism market in the tourism function, so the collection, processing, transmission, and utilization of tourism information occupy an important position in tourism. Considering this problem, a sports tourism service application model is established to process sports tourism information through a three-tier structure.The Internet of Things applied in the sports tourism service application model needs to have three layers, perception layer, network layer, and application layer, as shown in Figure4.(1)
Perception layer is the use of sensors, radio frequency identification, and other new generations of information perception technology to sense the identification of the facilities in sports tourism scenic spots and convert them into electrical signals or other required forms of information output, so as to meet the requirements of information transmission, processing, storage, display, recording, and control. It has been applied in this work [15].(2)
The network layer integrates various communication networks, transmits information as needed, and can use cloud computing technology, smart technology, and microelectronic technology to analyze and process a large amount of data information. The network layer generally includes the Internet, wireless communication networks, M2M communication networks, satellite communication networks, and cable television communication networks. System information can include natural and cultural environments, tourism resources, tourism facilities, and services at tourist destinations. The schematic diagram of the sports tourism function system is shown in Figure3. The information system connects users' electronic equipment, sports resources, and scattered information and data collected and stored in the information service organization for multi-party interaction and sharing, thereby realizing the data transmission of the event media operation service Internet of Things(3)
The application layer is an application service platform, which includes multiple subsystems, management networks, and full network management control modules belonging to different institutions and functional departments, which can carry out internal management control, external collaboration, and information release.Figure 4
Sports tourism service application model architecture.


### 2.3. Methods of Integration of Sports Tourism Resources

In this paper, the application model of sports tourism service is established by using Internet technology, through which the functions of information perception and information storage can be realized. In order to further promote the service quality of sports tourism service industry, the edge computing method is applied to sports tourism service, so as to realize the effective integration of sports tourism resources.


#### 2.3.1. Similarity Calculation of Sports Tourism Resources

In the process of calculating sports tourism resources, calculating the similarity of different types of resources can be divided into two parts: one is to calculate the similarity of feature words, the other is to calculate the similarity between the environments of sports tourism resources [16].Among them, the specific steps for calculating the similarity of feature words are as follows.UseSimw to represent the similarity of the feature words, and use the classification subtree to divide the feature words. The classification subtree is shown in Figure 5.Figure 5
Classification subtree.According to the classification results of the classification subtree, assuming there are two sports tourism resource feature words,wi and wj, calculate the similarity between wi and wj; the specific formula is as follows:(1)Simw=Iwi+wj=I−θh=I∏i=1nηien+I∑j=1nεηj.Among them,I represents the set of feature words; θ represents the key factor of feature word decomposition; h represents the estimated time of execution of feature word similarity calculation; n represents the similarity coefficient; ηi represents the sequence of execution of all subtasks; ηj represents the resources that can be directly corresponded to through resource allocation.When calculating the similarity between the environments of sports tourism resources, the similarity between the environments ofwi and wj is calculated, and the elements in the environment set need to be paired, and then the characteristic words similarity is calculated [17]. The calculation formula is(2)bj=1,∑i,j=1ncirj.Among them,ci represents a feature word with strong relevance; rj represents a related word with weak relevance.


#### 2.3.2. Sports Tourism Service Resource Integration Method Based on Edge Computing

Existing Internet of Things technology uses centralized data centers or clouds for data processing, which causes large network delays on the device side, inability to meet the explosive growth of devices, threats to device data security, and large errors in device data integration. In this context, edge computing is proposed and applied. Edge computing technology alleviates these defects of centralized Internet of things, transfers computing tasks to the edge service side, and significantly improves delay and energy consumption, especially for delay and energy sensitive applications of Internet of things [18]. Based on the calculation results of similarity of sports tourism resources, edge computing technology is used to integrate sports tourism service resources.An IOT architecture based on edge computing is established to integrate sports tourism service resources. The architecture consists of physical transaction layer, IOT edge device layer, edge gateway layer, and edge service layer. In this architecture, the edge gateway layer is composed of several edge gateways, which is denoted asFDs.Set upFDs private K to form a FDs set F1=FDs1,FDs2,…,FDsk, complete the resource perception and collection through the data source, and transmit the data to the edge service layer through resource preprocessing. The edge service layer is mainly responsible for remote cloud computing connections, providing global service ports for resource integration, controlling and managing EDs through commands, and realizing the scheduling of sports tourism service resources [19].Set upN edge servers to form a local edge set F2=SDs1,SDs2,…,SDsn. SDsn may be a micro-data center, micro-cloud computing, or intelligent router. It has computing capabilities to provide data storage and calculations near EDs.SetFDs local Q to form the local edge gateway layer F3=FDs1,FDs2,…,FDsq, and FDsq represents the edge gateway.In the edge gateway of the edge gateway layer, a virtualization controller is embedded to realize the provision of services to the upper edge service layer and the energy consumption and delay, application and task decomposition, and other application processing on the lower edge device layer. The middle part of the virtual controller is resource allocation and scheduling, and the lower layer is resource integration and delay analysis, where task decomposition and application processing are responsible for the effective allocation of resources [20]. The virtualization controller is built into the edge gateway of the edge gateway layer, which can handle most edge tasks, reduce the overall service delay and energy consumption of application requests at the edge device layer, and improve the satisfaction of tourists.Because the resource transmission in the Internet-based sports tourism service application model requires a certain amount of time and energy, the system's time delay, energy consumption, and service satisfaction are described. Transfer sports tourism service resources from the transmission equipment layer to the edge gateway layer, or transfer sports tourism service resources to the edge service layer through the edge gateway layer, and set the resource upload rate tovij. The calculation formula is(3)vij=∑i,j=1nxiyj.Among them,xi represents the edge gateway layer resource upload rate; yj represents the edge service layer resource upload rate. Since the download service time is relatively short, the time generated by the download service is ignored in resource integration.Assuming that the overall task of sports tourism service resource integration isG, in order to select a reasonable task allocation channel in resource integration, first obtain the channel allocation candidate solutions of all requested tasks and express them in the form of a matrix:(4)G=g11g12⋯g1ng21g22⋯g2n⋮⋮⋮⋮gn1gn1⋯gnn.Then, the channel allocation rate of all requested tasks is(5)Gv=∑i,j=1nexpvij×εLh2.Among them,ε represents the sending rate of the task request; L represents the channel bandwidth.When the size of the input data in the resource integration request task isdc, the processing cycle required to execute the task is Cij, the weight of the virtualization controller is μn, and the variance of the parameters of the sports tourism service resource is σ2. The integration value of the sports tourism service resource is(6)φk=Sm,nSm+τ,n+τ.Among them,τ represents the amount of data transferred.When0<φk≤1, the total mean square error of the integration of sports tourism service resources is(7)σ¯2=φk×sk|xkdsk.Among them,sk represents the time cost of task calculation offloading; xk represents the energy consumption caused by local computing, task offloading, and data transmission.Combining with the theory of multivariate function seeking extreme value, the minimum value of the total mean square error is calculated as(8)σmin=minsk|xk−Rd.Among them,Rd represents the weighting factor.Whenσmin<0, the weighting factor corresponding to the minimum value is(9)δi=limnlogNnεαlogσmin.Among them,Nnε represents the approximation coefficient of sports tourism service resources; α represents the scale function of sports tourism service resources.Using formula (9) to obtain the minimum value of the weighting factor, on this basis, reconstruct the characteristics of sports tourism service resources, and then obtain the final formula for the integration of sports tourism service resources:(10)Gτ=logcnGHx,Hy.Among them,cn represents the reconstructed sports tourism service resource; Hx represents the resource function of the sports tourism service resource in the x layer; Hy represents the y-th detailed resource function of sports tourism service resources. Figure 6 shows the integration process of sports tourism service resources.Figure 6
The integration process of sports tourism service resources.In summary, through the combination of the Internet and edge computing methods, the improvement of sports tourism services is realized.

Since the download service time is relatively short, the time generated by the download service is ignored in resource integration.Assuming that the overall task of sports tourism service resource integration isG, in order to select a reasonable task allocation channel in resource integration, first obtain the channel allocation candidate solutions of all requested tasks and express them in the form of a matrix:(4)G=g11g12⋯g1ng21g22⋯g2n⋮⋮⋮⋮gn1gn1⋯gnn.Then, the channel allocation rate of all requested tasks is(5)Gv=∑i,j=1nexpvij×εLh2.Among them,ε represents the sending rate of the task request; L represents the channel bandwidth.When the size of the input data in the resource integration request task isdc, the processing cycle required to execute the task is Cij, the weight of the virtualization controller is μn, and the variance of the parameters of the sports tourism service resource is σ2. The integration value of the sports tourism service resource is(6)φk=Sm,nSm+τ,n+τ.Among them,τ represents the amount of data transferred.When0<φk≤1, the total mean square error of the integration of sports tourism service resources is(7)σ¯2=φk×sk|xkdsk.Among them,sk represents the time cost of task calculation offloading; xk represents the energy consumption caused by local computing, task offloading, and data transmission.Combining with the theory of multivariate function seeking extreme value, the minimum value of the total mean square error is calculated as(8)σmin=minsk|xk−Rd.Among them,Rd represents the weighting factor.Whenσmin<0, the weighting factor corresponding to the minimum value is(9)δi=limnlogNnεαlogσmin.Among them,Nnε represents the approximation coefficient of sports tourism service resources; α represents the scale function of sports tourism service resources.Using formula (9) to obtain the minimum value of the weighting factor, on this basis, reconstruct the characteristics of sports tourism service resources, and then obtain the final formula for the integration of sports tourism service resources:(10)Gτ=logcnGHx,Hy.Among them,cn represents the reconstructed sports tourism service resource; Hx represents the resource function of the sports tourism service resource in the x layer; Hy represents the y-th detailed resource function of sports tourism service resources.

## 2.3.1. Similarity Calculation of Sports Tourism Resources

In the process of calculating sports tourism resources, calculating the similarity of different types of resources can be divided into two parts: one is to calculate the similarity of feature words, the other is to calculate the similarity between the environments of sports tourism resources [16].Among them, the specific steps for calculating the similarity of feature words are as follows.UseSimw to represent the similarity of the feature words, and use the classification subtree to divide the feature words. The classification subtree is shown in Figure 5.Figure 5
Classification subtree.According to the classification results of the classification subtree, assuming there are two sports tourism resource feature words,wi and wj, calculate the similarity between wi and wj; the specific formula is as follows:(1)Simw=Iwi+wj=I−θh=I∏i=1nηien+I∑j=1nεηj.Among them,I represents the set of feature words; θ represents the key factor of feature word decomposition; h represents the estimated time of execution of feature word similarity calculation; n represents the similarity coefficient; ηi represents the sequence of execution of all subtasks; ηj represents the resources that can be directly corresponded to through resource allocation.When calculating the similarity between the environments of sports tourism resources, the similarity between the environments ofwi and wj is calculated, and the elements in the environment set need to be paired, and then the characteristic words similarity is calculated [17]. The calculation formula is(2)bj=1,∑i,j=1ncirj.Among them,ci represents a feature word with strong relevance; rj represents a related word with weak relevance.


## 2.3.2. Sports Tourism Service Resource Integration Method Based on Edge Computing

Existing Internet of Things technology uses centralized data centers or clouds for data processing, which causes large network delays on the device side, inability to meet the explosive growth of devices, threats to device data security, and large errors in device data integration. In this context, edge computing is proposed and applied. Edge computing technology alleviates these defects of centralized Internet of things, transfers computing tasks to the edge service side, and significantly improves delay and energy consumption, especially for delay and energy sensitive applications of Internet of things [18]. Based on the calculation results of similarity of sports tourism resources, edge computing technology is used to integrate sports tourism service resources.An IOT architecture based on edge computing is established to integrate sports tourism service resources. The architecture consists of physical transaction layer, IOT edge device layer, edge gateway layer, and edge service layer. In this architecture, the edge gateway layer is composed of several edge gateways, which is denoted asFDs.Set upFDs private K to form a FDs set F1=FDs1,FDs2,…,FDsk, complete the resource perception and collection through the data source, and transmit the data to the edge service layer through resource preprocessing. The edge service layer is mainly responsible for remote cloud computing connections, providing global service ports for resource integration, controlling and managing EDs through commands, and realizing the scheduling of sports tourism service resources [19].Set upN edge servers to form a local edge set F2=SDs1,SDs2,…,SDsn. SDsn may be a micro-data center, micro-cloud computing, or intelligent router. It has computing capabilities to provide data storage and calculations near EDs.SetFDs local Q to form the local edge gateway layer F3=FDs1,FDs2,…,FDsq, and FDsq represents the edge gateway.In the edge gateway of the edge gateway layer, a virtualization controller is embedded to realize the provision of services to the upper edge service layer and the energy consumption and delay, application and task decomposition, and other application processing on the lower edge device layer. The middle part of the virtual controller is resource allocation and scheduling, and the lower layer is resource integration and delay analysis, where task decomposition and application processing are responsible for the effective allocation of resources [20]. The virtualization controller is built into the edge gateway of the edge gateway layer, which can handle most edge tasks, reduce the overall service delay and energy consumption of application requests at the edge device layer, and improve the satisfaction of tourists.Because the resource transmission in the Internet-based sports tourism service application model requires a certain amount of time and energy, the system's time delay, energy consumption, and service satisfaction are described. Transfer sports tourism service resources from the transmission equipment layer to the edge gateway layer, or transfer sports tourism service resources to the edge service layer through the edge gateway layer, and set the resource upload rate tovij. The calculation formula is(3)vij=∑i,j=1nxiyj.Among them,xi represents the edge gateway layer resource upload rate; yj represents the edge service layer resource upload rate. Since the download service time is relatively short, the time generated by the download service is ignored in resource integration.Assuming that the overall task of sports tourism service resource integration isG, in order to select a reasonable task allocation channel in resource integration, first obtain the channel allocation candidate solutions of all requested tasks and express them in the form of a matrix:(4)G=g11g12⋯g1ng21g22⋯g2n⋮⋮⋮⋮gn1gn1⋯gnn.Then, the channel allocation rate of all requested tasks is(5)Gv=∑i,j=1nexpvij×εLh2.Among them,ε represents the sending rate of the task request; L represents the channel bandwidth.When the size of the input data in the resource integration request task isdc, the processing cycle required to execute the task is Cij, the weight of the virtualization controller is μn, and the variance of the parameters of the sports tourism service resource is σ2. The integration value of the sports tourism service resource is(6)φk=Sm,nSm+τ,n+τ.Among them,τ represents the amount of data transferred.When0<φk≤1, the total mean square error of the integration of sports tourism service resources is(7)σ¯2=φk×sk|xkdsk.Among them,sk represents the time cost of task calculation offloading; xk represents the energy consumption caused by local computing, task offloading, and data transmission.Combining with the theory of multivariate function seeking extreme value, the minimum value of the total mean square error is calculated as(8)σmin=minsk|xk−Rd.Among them,Rd represents the weighting factor.Whenσmin<0, the weighting factor corresponding to the minimum value is(9)δi=limnlogNnεαlogσmin.Among them,Nnε represents the approximation coefficient of sports tourism service resources; α represents the scale function of sports tourism service resources.Using formula (9) to obtain the minimum value of the weighting factor, on this basis, reconstruct the characteristics of sports tourism service resources, and then obtain the final formula for the integration of sports tourism service resources:(10)Gτ=logcnGHx,Hy.Among them,cn represents the reconstructed sports tourism service resource; Hx represents the resource function of the sports tourism service resource in the x layer; Hy represents the y-th detailed resource function of sports tourism service resources. Figure 6 shows the integration process of sports tourism service resources.Figure 6
The integration process of sports tourism service resources.In summary, through the combination of the Internet and edge computing methods, the improvement of sports tourism services is realized.

## 4. Conclusion

At present, the development of sports tourism service industry is in the stage of rapid development, but the development of information technology is still relatively backward. Most of the sports tourism services still stay in the traditional operation mode. Their organization ability is limited, and the overall efficiency of the operation is not high, and the consumption of the resource is huge. These problems seriously restrict the sustainable development of sports tourism service industry. Under the background of the great development of Internet information, it has become a trend that the development of sports tourism service industry depends on information technology. It is inevitable to pay attention to resource integration and the optimization of the whole process of sports tourism service industry management. The Internet of Things plays an important role in the field of sports tourism service industry. This paper chooses the application of Internet of Things technology and edge computing technology in sports tourism service as the research object. The experimental results show that, compared with traditional methods, the proposed method has obvious advantages in the aspects of sports tourism data retrieval time, sports tourism data fusion error, and sports tourism service management energy consumption. The research results are useful for sports tourism service industry Internet of Things technology research and development, application research, and management personnel to provide a certain reference value. The innovation of this paper focuses on the construction of the sports tourism services system, but there is still room for improvement in the similarity calculation method and edge calculation method. In the future work, we will focus on the innovation of the method.
