摘要
设计了一套基于虚拟仪器(LABVIEW)的车用压力传感器自动化校准系统.该系统采用模糊参数自整定PID控制器和高低温箱,分别实现系统压力和温度的自动化精确控制,上位机通过RS232接口与高低温箱的控制器进行通信.实验结果表明,校准后的传感器的输出误差在0.1%以内,系统精度较高.系统的各项技术参数均能够满足汽车工业中大批量生产压力传感器的情形.
A car pressure sensor calibration system based on LABVIEW was designed.Fuzzy adaptive PID controller and high-low temperature chamber were used.The system could realize the function of automatic and precise control of pressure and temperature.The system communicated with the controller of high-low temperature chamber through a port of RS232.The experimental results showed that the error of the calibrated pressure sensors was within 0.1%.The precision and other technical parameters of the system can meet the requirements of pressure sensor calibration in car manufacturing.
