According to the special needs of the airport electric vehicle, this paper designs a vehicle intelligent terminal based on STM32, in which the analog-digital conversion technology, GPS technology and WIFI technology are used. The trminal equipment is used to collect the vehicle battery voltage and current which are made to do the analog-to-digital conversion in order to measure out the remaining charge, meanwhile the vehicle terminal can be used to transfer the battery charge information and GPS location infor-mation to the monitoring center via WIFI wireless network and the monitoring center can be also used to send commands to the vehi-cle intelligent terminal according to the received vehicle information, thus achieving the optimal scheduling of the airport vehicles, col-lision warning and other functions. Experimental operation results show that the system modules can meet the actual needs.%根据机场电动车辆的特殊需求,设计了一套以STM32芯片为核心,结合模数转换技术、GPS技术和WIFI技术的车载智能终端.终端设备采集车辆电池电压、电流等模拟量进行模数转换并测算出剩余电量,同时将电池电量信息和GPS定位信息通过WIFI无线网络传输至监控中心,监控中心根据接收到的车辆信息向车载终端发出指令,实现机场车辆的优化调度、防撞预警等功能.实验运行结果表明,系统各功能模块满足实际需求.
