【Abstract】 In the design of data acquisition system, communication protocol, communication way and choice of system framework are very important. Based on the view of the practical application and the expansion of the system, a kind of data acquisition system is put forward-wireless long-range data acquisition system based on Modbus Protocol which is suitable when data sources often disperse relatively and situate far from the control center in a data acquisition system. The standard communication protocol-Modbus Protocol and its application to the wireless long-range data acquisition system are introduced, and it provides the design of system hardware and the implementation method of the software are provided.更多还原
