摘要
搭建了集成嵌入式和PC机控制的多功能模块化电液比例控制实验台,可实现对电液比例变量泵和比例阀的性能测试。测控系统硬件以ARM9 S3C2440为内核的嵌入式开发板、PC机为上位机、以USB7660AD数据采集卡为下位机,通过上下位机的通信实现传感器信号的传送以及对电液比例阀和电磁阀的监控。采用Lab VIEW软件及其Touch Panel模块进行图形化编程,设计出相应的测控程序并进行试验。结果表明,该试验台性能稳定,能满足实验教学的需要。
A modular multifunction electro-hydraulic proportional control test bench is designed, which integrated embedded control and PC control. The measurement and control system hardware equipped with ARM9 S3C2440 as the kernel of the embedded development board and PC is upper machine, USB7660 AD data acquisition card for lower computer, through the communication between upper and lower machine to send and receive test bed of sensor signal and monitor the electro-hydraulic proportional valve and solenoid valve. The software of test bench used the Labview graphical programming and Touch Panel module, to design the corresponding application and conduct a test.The results show that, the experiment and measurement and control system have a stable performance, high control precision.
