Signal Acquisition and Monitoring System Design of a Car

为了观测汽车在不同工况下的各项参数以便利于对结构进行优化,设计了汽车状态监测系统。该系统以TMS320F2812为控制核心对长城哈弗H6汽车进行测试,应用ADC模块和EV模块采集汽车的电压、电流、转速、节气门开度以及冷却液温度等实时信号,通过SCI模块将采集信号传输给上位机,并使用Labview软件实现了数据实时显示并存储。介绍了该系统的硬件电路设计和软件编程的方法,通过试验测试,验证了该系统的可行性。试验测试结果与实际情况基本相符,为汽车的故障诊断与排除提供了数据依据,对汽车结构部件的进一步优化具有一定的参考意义。

In order to observe the various parameters of a car in different operating conditions and op- timize the structure, the monitoring system is designed. It tests HAVAL H6 based on the control core of TMS320F2812. The system uses ADC module and EV module to collect the real-time signals inclu- ding voltage, current, rotating speed, throttle percentage and coolant temperature, then transmits the signals to PC through the SCI module. It uses the Labview software to display and storage the data. This design mainly introduces the hardware circuit and software programming method. It verifies the feasibility of the system and shows that the test result is consistent with actual situation. It provides the basis for automobile fault diagnosis and eliination, and has a certain reference for the further optimiza- tion of automobile structure.
