|
摘要
为降低工业设备的维护成本,建立现场输入信号的云平台监测系统。为建立云平台监测系统,设计STM32的数据传输硬件和云平台系统,数据传输硬件模块包括100Mbps以太网接口和RS485通讯电路,开发云平台系统和人机交互界面,利用信号发生器和PLC控制系统验证监测系统。实验结果系统可以实现0.05s的快速读取,且电压幅值误差在5%以内。结果表明监测系统可以灵活应用到各类工业控制系统中。
In order to reduce the maintenance cost of industrial equipment, a cloud platform monitoring system for field input signals is established. In order to establish the cloud platform monitoring system, the data transmission hardware and cloud platform system of STM32 are designed. The data transmission hardware module includes the 100 Mbps Ethernet interface and the RS485 communication circuit, develops the cloud platform system and the human-computer interaction interface,and uses the signal generator and the PLC control system to verify the monitoring system. The experimental results show that the system can read 0.05 s quickly and the error of voltage amplitude is less than 5%. The results show that the monitoring system can be applied to various industrial control systems flexibly.
