介绍了一种基于STM32的低功耗,高性能的喷淋阀检测系统,描述了该系统的基本框架结构和工作原理。利用STM32自带的丰富的功能模块实现喷淋阀数据的多通道数模转换与基于MODBUS协议的RS48远程通信,并利用其PWM波形的输出和高速运算能力实现鼓风机喷口温度的闭环控制。最后应用LABVIEW实现检测数据的实时传输和打印。实际运行表明,该检测系统具有实时性好、可靠性高、成本低、人机交互友好等优点。

This paper introduced a low-power-consumption and high-performance sprinkler valve detecting system based on STM32, and expatiated on its basic framework and the operational principle. STM32’s abundant function modules helped the system to realize multi-channel synchronous analogue-to-digital conversions and the RS485 remote communication base on MODBUS protocol,whose PWM output and high-performance computing contributed to realize the closed-loop control of blower nozzle temperature .Based on LABVIEW , the real-time transfer and printing of detecting date were on used. The practical operation attested for the improved real-time performance and reliability of the system which was of low cost and friendly human-computer interaction.
