Transformer substation safety management system based on Internet of things

Abstract

The invention discloses a transformer substation safety management system based on the Internet of things. The system comprises a server, an exchanger, an internal exchanger, a front-end processor, a WSN node and a mobile terminal, wherein the server is connected and communicated with the exchanger through an internal local area network, the exchanger is connected and communicated with the internal exchanger through a power line carrier network, the internal exchanger is communicated with the front-end processor through a medium-voltage bandwidth power line carrier overhead line and an optical fiber in a mixed connected mode, and the front-end processor is communicated with the mobile terminal through the WSN node of a self-organization network of a Zigbee wireless sensor. Safety operation management, equipment monitoring and environment perception of a transformer substation are achieved, and the communication bottleneck problem of the last one kilometer of a distribution network is effectively solved through hybrid networking of low-voltage and medium-voltage communication access networks.

Description

technical field [0001] The invention relates to a substation safety management system, in particular to a substation safety management system based on the Internet of Things. Background technique [0002] Substation is a high-risk work area. If the management is not in place, accidents may occur if you don't pay attention. Under the current people-oriented call, all work in the substation puts personal safety first. However, in addition to the restrictions of rules and regulations such as operating procedures and safety treaties, there is no practical and feasible means of safety protection for active alarms. Therefore, if the operator makes mistakes, misjudgments, or laziness, arbitrariness, patrols stray into the interval, etc., it may directly or indirectly lead to the occurrence of accidents, threatening personal safety and loss of economic benefits. [0003] Smart substation is an important foundation and support for a strong smart grid. It has the characteristics of...
