Research on wireless sensor network in automobile comprehensive performance testing system

A kind of automobile comprehensive performance testing system based on wireless sensor networks is introduced by this paper. The system consists of a portable computer, the USB-Wireless protocol conversion module and wireless data acquisition module, which can be suitable for various types of vehicle performance testing. Portable computer communication with data acquisition module through USB-Wireless protocol conversion module. Optimum anti-collision algorithm is adopted in wireless transmission part, and the system synchronous data acquisition between different modules can be realized by time compensation. Test results show that, the data transmission is stable and reliable, high precision, high modularization, strong real-time performance and excellent portability.
