Substation Wireless Data Acquisition System Based On Internet Of Things Technology

The Internet of things is another revolutionary technology after the Internet,Over the years the Internet of things technology has been applied to all walks of life,such as agricultural production, intelligent transportation, industrial production and so on,which also includes electric power network system.The network system is implemented in the substation, substation wireless data acquisition is a key part of the whole system.The wireless data acquisition system for power plant requires the use of Key-Technology in Internet of things,such as advanced wireless communication technology, remote data transmission technology and Internet technology.Through the implementation of equipment of all kinds of sensors in real-time monitoring, through wireless transmission technology to complete data upload,through the network service detection data display, intelligent alarm and remote control analysis of substation environment data query.In order to realize the monitoring and control of the temperature data of each switch cabinet, this paper focuses on the wireless sensor technology and the application of automatic control technology in wireless data acquisition system,and build the Internet data monitoring, temperature display and alarm platform.Perception layer using low power consumption on STC single chip microcomputer, wireless module and stable sensor to complete the real-time collection and transmission of the temperature of the switch cabinet.Introduction of PID control algorithm on the basis of monitoring data to control the device temperature within certain limits.The network layer uses the GPRS module for data exchange network. The application layer temperature data acquisition and storage of the corresponding database, in order to complete the form of interactive web page display and node parameters of each node temperature state configuration.
