## 4 Case Study Investigation
### Data Management System  
The system linked the monitored data in real time. The remote viewing of production data by internet-based mobile devices helped construction parties, owners, third-party supervisors, and other departments to conduct real-time production quality inspections. The data linkage module architecture and system display are shown in Figure 9.  
(1) The system automatically performed data sharing and data linkage with the production, mixing station, vehicle transportation, paving, and compaction systems, and links with the production data of the mixing station, the vehicle data, and the paving and compaction data in real time. It has the following main functions: Firstly, the system displays the current paving and compaction mileage in a graphic form. In the Figure 10, the paved mileage of each batch of transportation and the corresponding batch of the mixture used can be directly related to the paving and pressing data. Secondly, the display provides the quantity of the corresponding module, and the corresponding alarm data information can be associated with the actual quantity. Furthermore, it is possible to click on the total production batch to display the current number of production data batches, and at the same

time display the data with a warning in color. Finally, users can click the transport data batch that displays the current number to view the details of the number of productions transported by each batch of transport vehicles, and color prompts for data with early warning are also provided.  
(2) The paving pile number corresponds to each batch of transport materials and the corresponding batch of the mixing production material can be visually checked on the paving and compaction effect diagram(As shown in Figure 11). This can also be linked to the corresponding pile number section for paving, and the compaction can be videosed, as well as the driving track of the transport vehicle, and the production data information of the mixing material.  
(3) Historical traceability and playback can be performed on the corresponding data of each batch of truck paving stakes on the paving and compaction renderings.  
(4) The platform provides system analysis and early warning to automatically link early warning data of various systems, and provides a centralized early warning prompt for each construction link.  
(5) Finally, the platform supports the access of relevant data to the provincial management platform, and realizes the data connection and business integration with the existing
