     PREFERRED EMBODIMENTS OF THE PRESENT APPLICATION 
     In the following descriptions, in order to illustrate but not to limit the present application, specific details such as a specific system structure, techniques or the like are proposed, thereby facilitating a thorough understanding of embodiments of the present application. 
     In order to illustrate the technical solution in the present application, the present application is described with reference to particular embodiments below: 
     Firstly, an embodiment of the present application with reference to  FIG. 1  provides a schematic block diagram of system architecture of a maintenance station management system, the system architecture involved in the technical solution of the embodiment of the present application, and some possible application scenarios are introduced by examples. 
     The maintenance station management system shown in  FIG. 1  comprises a data management server  11 , a block chain containing a plurality of block chain node devices serving as block chain nodes, a first user client  13  and a second user client  14 . The data management server  11  are connected in communication with the block chain  12 , the first user client  13  and the second user client  14  are connected with the data management server  11  in communication respectively. 
     It needs to be explained that, the data management server  11  can either be a single server that communicates with a block chain node device, thereby accessing the block chain  12 , or be registered in the block chain  12  and become a node device of the block chain. The data management server  11  is integrated with data management platform program used for managing the maintenance station. 
     The aforesaid first user client  13  can be a maintenance transaction client, a user can finish a transaction operation such as reservation, usage and payment of the maintenance station and so on related to the maintenance station through the maintenance transaction client. The second user client can be client of an investor, that is, the investor can get to know an operation condition of the maintenance station and relevant information of other maintenance stations, or manage the maintenance station. The aforesaid investor is referred to as the investor of the maintenance station, which can either be an owner of the maintenance station or be a renter or a purchaser of the maintenance station. The aforesaid maintenance station is referred to as a site for performing maintenance. 
     The investor rents or purchases the maintenance station, brings a plurality of cooperation partners including an owner of the maintenance equipment, an operation and maintenance team and an operator of the data management platform together to constitute the maintenance station capable of providing maintenance services for users who need service of maintenance. The maintenance service provided by the maintenance station can be automobile maintenance service, and is not restricted to automobile maintenance service, the maintenance service can be, for example, an electrical equipment maintenance service. 
     For example, the maintenance station can be, in particular, the automobile maintenance station, the first user client  13  can be, in particular, a client of a maintenance technician. After the maintenance station is rented or repaired, the investor of the maintenance station searches and brings the owner of the automobile maintenance equipment, the operation and maintenance team of the maintenance station together to constitute the maintenance station capable of providing automobile maintenance service, then, the plurality of cooperation partners come to a usage agreement of the maintenance station including a maintenance station reservation rule, maintenance service item information, a charging rule and an income sharing rule by negotiation, the usage agreement is submitted by the investor of the maintenance station to the data management server through the second user client  14 , and then is sent to the block chain node device by the data management server, such that the block chain node device registers the usage agreement in the form of usage smart contract into the block chain. A vehicle owner who wants to have automobile maintenance service needs to issue an automobile maintenance order on the first user client, the automobile maintenance order can include but is not limited to automobile maintenance item information and maintenance time information. After the maintenance technician receives the automobile maintenance order issued by the vehicle owner through the first user client, a proper maintenance station is reserved for use; wherein, a maintenance technician is required to determine relevant information including maintenance time, related information of the vehicle (e.g., vehicle license plate information) to be maintained, maintenance service needed to be used during reservation, a reservation use request of the maintenance station from the maintenance technician will be sent to the data management server to be stored. 
     After the reservation is successful, the maintenance technician acquires the vehicle of the vehicle owner to be maintained, and uses the maintenance station to perform maintenance for the vehicle to be maintained, the maintenance technician submits a transaction request to the data management server through the first user client, the data management server detects the permission of usage of the maintenance technician (i.e., the first user) according to the transaction request; for example, the data management server detects whether the first user has been registered or not, and whether a deposit is paid or not. If the permission of usage is met, the usage smart contract is called, and the corresponding permission of usage of the maintenance station is open to the maintenance technician. When the automobile maintenance technician finishes using the maintenance station, an end use instruction is sent to the data management server through the first user client, the data management server sends a transaction payment request to the first user client after the use cost that needs to be paid by the maintenance technician is determined according to service condition of the maintenance technician and a charging rule of the usage smart contract; the maintenance technician pays the corresponding use fee through the first user client. After receiving the information indicating that the transaction is finished, the data management server calls a transaction sharing rule of the usage smart contract to share the maintenance income to all cooperation partners (the maintenance station investment party, the owner of the maintenance equipment, the maintenance station operation and maintenance team, and management party of the data management platform), and then sends the transaction information such as maintenance income information, income sharing information, and use record information of the maintenance technicians and the like to the block chain to be recorded; the block chain node device receives the transaction information submitted by the data management server and registers the transaction information into the block chain. 
     The technical solution provided by the embodiment of the application based on the architecture of the maintenance station management system is described fully and in detail below. 
     Please refer to  FIG. 2 ,  FIG. 2  illustrates a schematic flow block diagram of the maintenance station management method provided by the embodiment of the present application, the method can comprise following steps: 
     Step  201 , receiving, via a data management server, a transaction request of using a maintenance station from a first user, calling a usage smart contract of the maintenance station to grant a permission of usage of the maintenance station to the first user according to the transaction request. 
     It should be noted that, the usage smart contract is generated based on a usage agreement of the maintenance station. The usage agreement of the maintenance station can include a reservation rule, a usage agreement, maintenance service item information, a charging rule and an income sharing rule of the maintenance station. The plurality of cooperation partners including the maintenance station investment party, the owner of the maintenance equipment, and the maintenance station operation and maintenance team, the management party of the data management platform come to the usage agreement of the maintenance station aiming at the service rule of the maintenance station and relevant income sharing rule, and the usage agreement of the maintenance station is submitted to the data management server by the maintenance station investment party, and then is sent to the block chain node device by the data management server, such that the block chain node device generates the usage smart contract based on the usage agreement and registers the usage smart contract in the block chain so as to be broadcasted in a whole network. The usage smart contract can make a transaction which is generated by performing usage smart contract through doing corresponding action (e.g., starting to provide the maintenance station for the user to use) under the condition (e.g., the condition that the smart contract is triggered to be executed can be receiving a code scanning operation of the user) that the usage smart contract is triggered to be executed according to a plurality of pre-determined rules. 
     Wherein, the aforesaid maintenance station reservation rule can comprise relevant rules when the user reserves the maintenance station; the charging rule comprises cost rules of various maintenance services of the maintenance station; the income sharing rule comprises maintenance income sharing proportion of the various cooperation partners; the maintenance service item information is referred to as a maintenance service type which can be provided by the maintenance station. 
     The first user can be a user of the maintenance station, and can be particularly represented as the maintenance technician; of course, if the vehicle owner has the corresponding maintenance skill, he/she can also be represented as the vehicle owner of the vehicle to be maintained. 
     The transaction request can include but is not limited to user information of the first user, and related information of the transaction request and the like. The transaction request can be, in particular, triggered by the first user by scanning corresponding two-dimensional code of maintenance station through the first user client; for example, after the first user arrives at the maintenance station in the reservation time period, he/she uses the two-dimensional codes provided by using the first user terminal side to scan the client scanning maintenance station to sign in or utilize the maintenance resources in the maintenance station. Certainly, the transaction request can also be triggered by other approaches, for example, trigged by iris, sound, fingerprint and other biological characteristic information of the first user, the transaction request can also be triggered by license plate information of the vehicle to be maintained. 
     After receiving the transaction request, the data management server determines whether the current user meets the usage agreement in the usage smart contract according to relevant information carried by the transaction request; for example, whether current time is within the reservation time period of the user, whether the user is authenticated by the technician and whether the user pays a deposit is judged. If the usage agreement is met, the corresponding permission of usage of the maintenance station is open to the current user. 
     The permission of usage of the maintenance station can be a passing authority of gate machine of the maintenance station, a service authority of maintenance equipment in the maintenance station, and the like, particularly, relevant permission can be open to the user by sending a passing password or use password of related permission to the first user client; or as an alternative, the relevant permission can be open to the user by sending an instruction to relevant equipment via the data management server. After the permission of usage of the maintenance station is open to the first user, the first user can use the maintenance resources of the maintenance station to perform maintenance operation for the vehicle to be maintained. For example, after an access permission of the maintenance station is open to the first user, the data management server will send a passing instruction to the gate or an entrance/exit of the gate of the maintenance station, the first user can drive the vehicle to be maintained to pass through the gate or the entrance/exit of the gate, and then use the service authority of the maintenance resources to perform vehicle maintenance. 
     Step  202 , submitting, via the data management server, a transaction payment request when the first user finishes using the maintenance station, and calling the usage smart contract to finish the payment transaction according to the transaction payment confirmation instruction of the first user, and performing a sharing according to the transaction sharing rule of the usage smart contract. 
     Particularly, when the first user finishing using the maintenance station, the data management server calculates charge amount of the transaction according to the charging rule in the usage smart contract and use condition (e.g., service time, the type of the used equipment) of the first user after an end use instruction sent by the first user client is received, and sends a payment request containing the charge amount to the first user, the first user receives the transaction payment request through the first user client and performs corresponding payment operation. 
     After the first user finishes the payment, the data management server calls the usage smart contract on the block chain to finish the payment transaction, and share the maintenance income according to the transaction sharing rule in the usage smart contract. 
     The transaction sharing rule includes sharing proportion information of the income generated by the transactions previously achieved by various cooperation partners (i.e., the maintenance station investment party, the owner of the maintenance equipment, the maintenance station operation and maintenance team, the management party of the data management platform) and written into the usage agreement. 
     For example, the share proportion of the maintenance station investment is 50%, the share proportion of the maintenance equipment is 40%, the share proportion of the operation and maintenance team of the maintenance station is 5%, and the share proportion of the management party of the data management platform is 5%. When the maintenance income is 100 RMB, according to the transaction dividing rule, the shared income share of the investment party of the maintenance station is calculated to be 50 RMB, the shard income of the owner of the maintenance equipment is calculated to be 40 RMB, the shard income of the maintenance station operation and maintenance team is calculated to be 5 RMB, and the shared income of the management party of the data management platform is calculated to be 5 RMB. Since the technician has come to agreement with the vehicle owner regarding the maintenance service cost before the maintenance station is used, the income in the present application is the rental fee required to be paid for renting the maintenance station, thus, with regard to income sharing, the technicians are unconsidered. 
     It can be understood that, the calculation time of the income can be periodic and can also be real-time. That is, income sharing of the various cooperation partners are automatically calculated for every preset time period, for example, the usage smart contract is called to calculate the income sharing of the various cooperation partners from the block chain based on the transaction information stored on the block chain node device for every month; or as an alternative, the income of the cooperation partners can be calculated in real time, once the transaction is made, the calculation is performed one time. Certainly, the income sharing can also be calculated according to calculation requirement of the user. 
     Step  203 , receiving, via the block chain node device, the transaction information submitted by the data management server and registering the transaction information into a block chain. 
     It should be noted that, said transaction information is referred to as the transaction information between the first user and the maintenance station, and can include all information generated in the transaction process including the maintenance cost paid by the first user, the service time period of the first user, the service time duration, and the calculated income sharing. 
     The data management server sorts and packages the related information generated in the transaction process and uploads the related information to the block chain node device, the block chain node device stores the received transaction information and broadcasts the transaction information in a whole network. 
     In this embodiment, the maintenance station is enabled to provide maintenance service to the external in the form of a shared maintenance station, an idle rate of maintenance site can be reduced, and an utilization rate of the maintenance site can be improved; moreover, the transaction process of the maintenance station relies on the usage smart contract on the block chain, and the income sharing is calculated automatically using the transaction sharing rule of the usage smart contract, such that the transparency, the reliability and the convenience of the transaction process of the maintenance station and the computational process of the income sharing are improved.
