基于SPI驱动的智能调节阀控制系统研究
Research on intelligent regulating valve control system based on SPI drive
摘要
Abstract
In view of the valve opening control requirement of the pneumatic regulating valve in industrial process control field,an MSP430 SCM based intelligent valve position opening control system with SPI drive display is studied. The hardware system is composed of MSP430 drive circuit,sampling circuit,back-end PWM drive,and peripheral functional chip. In the soft-ware system,the modular design idea is adopted and the CPU enters low power consumption mode by means of interruption to reduce power consumption of the system and improve work efficiency. The test results show that the system has the characteris-tics of digitalization,intelligence and fast response in comparison with the traditional valve position regulation and control device applying the force balance principle.关键词
