C #-based vehicle communication system of detection

Automatic detection of line is often long distance and speed. In order to test the car with the main control room staff have good communication and coordination, this paper, C # language running on WinCE development of a communication system on the system, so that it can use wireless LAN to receive the test command, the transmission test vehicle information, access test results, test information storage and query. Outdoor test environment on a survey vehicle for testing the technical requirements of the project, by the system function modules, the rationale for setting the software design process, to determining the structure of software testing communications systems, using C # language for automotive wireless outdoor detection Communication system software, build software test platform, complete testing of automotive outdoor wireless communication system development and testing. This article first systematic exposition of the test communication systems and automotive-related technologies and protocols.Analysis of the overall system requirements. Based on these system requirements, starting the whole system. In the overall design gives the overall system structure, hardware and system software, select the C / S that is client / server model. Then, according to the characteristics of TCP communication protocol data communication protocols developed to ensure that the client and server-side transceiver test the accuracy of the information. Then by the system function modules and the software design process. After giving the overall design, it began to detail the specific design work. First select the SQL Server 2005 as a database communication system in this test system, then code to create the database and data tables. Then, the server-side programming, respectively, and the details of client functional modules. After the completion of the system design, according to the software design process, the system was functional and load testing. The results show that prior to testing communications systems to meet the basic needs of the proposed system. Final paper was a C #-based communication system of automotive testing, this system can serve as a subsystem of outdoor detection system to help them complete the main control room of outdoor and indoor testers communication, greatly improving the detection efficiency. And thanks to a mixture of symmetric and asymmetric encryption algorithm to protect the security of communications throughout the test system.
