计算机测控系统是汽车道路模拟试验台的关键部分。在研制国产化的汽车道路模拟系统过程中 ,开发了专用的计算机测控系统。分析了道路模拟试验对测控系统的特殊要求 ,构成测控系统时只采用了通用的廉价硬件插卡模块 ,而系统要求的大容量不间断采样与输出、数据输入和输出同步等特殊功能 ,采用复杂的编程用软件方法实现。这种方案构成的系统具有很高的性能价格比 ,从而为降低所研制的道路模拟系统的成本打下了很好的基础。实验证明 ,所开发的测控系统配置合理且能达到很高的精度。
Computer monitoring and control system is a key part of the automobile road simulation test bench. In the development of domestic automobile road simulation system, the development of a dedicated computer monitoring system. The special requirements of the road test system for the measurement and control system are analyzed. Only the common low-cost hardware card module is used to form the measurement and control system, while the system requires large capacity non-stop sampling and output, data input and output synchronization and other special functions, Programming using software methods. The system constituted by this kind of scheme has a high performance-price ratio, which lays a good foundation for reducing the cost of the road simulation system developed. Experiments show that the developed measurement and control system is reasonable and can achieve high precision.
