Substation Safety Operation Monitoring System Based on Internet of Things Technology

The existing wireless technologies for substation operation safety monitoring include WiFi, RFID, ZigBee, CSS and other wireless positioning technologies, but due to poor positioning accuracy, it is difficult to meet the needs of applications. IoT technology has a variety of information sensors, powerful information collection and communication functions, and can provide advantages such as precise positioning. For a high-risk industry such as substations, it is also essential to monitor the safe operation of substations. Therefore, IoT technology is safe in substations. The application of operation monitoring has also become a research hotspot. In this paper, three positioning algorithms such as TOA, TDOA and AOA are proposed, and the positioning accuracy of TDOA is determined by the positioning accuracy measurement experiment. Therefore, TDOA can be selected for the positioning of the operator’s position by the monitoring system. The information transmission function transmits the location information of the operator to the monitoring background. When the operator exceeds the safe area, the system will alarm and remind to ensure the safety of the personnel.
