Wireless remote data acquisition system based on Modbus protocol[Copy link]
Abstract: In the design of data acquisition system, the choice of communication protocol, communication mode and system architecture is very important. From the perspective of practical application and considering the scalability of the system, a data acquisition system is proposed for the situation that the data source is often scattered and far away from the control center: wireless remote data acquisition system based on Modbus protocol. The standard communication protocol: Modbus protocol, and its application in wireless remote data acquisition system are introduced, and the hardware design and software implementation method of the data acquisition system are given .
