Wireless remote terminal control system based on Zigbee technology

Abstract

The invention relates to a control system, and particularly relates to a control system of a remote terminal. The wireless remote terminal control system based on a Zigbee technology, which is provided by the invention, comprises a main controller, a power supply, an analog acquisition module and a Zigbee wireless module. The main controller is respectively electrically connected with the power supply and the analog acquisition module. The main controller and the Zigbee wireless module are connected through a serial communication interface. The wireless remote terminal control system based on the Zigbee technology, which is provided by the invention, solves the problems that the coverage of a point to point communication network is small and the network is affected by slave node adding and deleting of point to point communication.

Description

Technical field [0001] The invention relates to a control system, in particular to a remote terminal control system. Background technique [0002] At present, the commonly used wireless remote terminal control system (RTU) mostly works in a point-to-multipoint mode, namely: a central node, multiple slave nodes, and the central node communicates with the slave nodes to achieve wireless data transmission. The problem is that the coverage distance of communication is limited by the transmission power and receiving sensitivity of the central node, so the communication distance is relatively short, and it is troublesome to add and delete network nodes. Zigbee technology is currently widely used in the field of Internet of Things, but there are not too many data collection devices used in industry. Zigbee technology can realize multi-sensor networks in the field of industrial data collection with its self-organizing network and low power consumption. , Data collection function of ad h...
