Embodiment Construction

[0026] The present invention will be further described below in conjunction with the drawings.

[0027] Such as figure 1 As shown, the ZigBee-based high-voltage equipment temperature monitoring system of the present invention includes a monitoring center 4, an RS485 bus 3, no less than one RS485 gateway 1 and several ZigBee terminal nodes corresponding to each RS485 gateway 1. A ZigBee terminal node and a corresponding ZigBee coordinator form a star-shaped ZigBee network through a wireless connection. The RS485 gateway 1 includes a ZigBee coordinator and an RS485 forwarding module; the ZigBee terminal node is used to collect temperature data from high-voltage equipment monitoring points, RS485 Gateway 1 is used to forward data to the monitoring center through the RS485 bus.

[0028] figure 1 The ZigBee coordinator and several corresponding ZigBee terminal nodes form the ZigBee wireless network transmission module 2. Several ZigBee terminal nodes collect the temperature of the monit...

Abstract

The invention relates to the field of power equipment safety monitoring, in particular to a high-voltage equipment temperature monitoring system based on the ZigBee wireless sensor network technology. The high-voltage equipment temperature monitoring system comprises a monitoring center, RS 485 buses, at least one RS 485 gateway and a plurality of ZigBee terminal nodes corresponding to the RS 485 gateways respectively. Each RS 485 gateway comprises a ZigBee coordinator and an RS 485 forwarding module. The ZigBee terminal nodes are in the dormant state at ordinary times, temperature sensors in the ZigBee terminal nodes trigger interruption when the temperature of monitoring points is higher than a preset value, the interruption awakens the ZigBee terminal nodes so that the ZigBee terminal nodes can upload high temperature alarm information to the monitoring center in time, and therefore the problem that when ZigBee terminal nodes are in the dormant state, a monitoring system can not deal with sudden temperature rise of monitoring points or acquire high temperature alarm information in time is solved. The high-voltage equipment temperature monitoring system has the advantages of being low in cost and power consumption, high in real-time performance and reliability and good in usability.

Description

Technical field [0001] The invention relates to the field of power equipment safety monitoring, in particular to a high-voltage equipment temperature monitoring system based on ZigBee wireless sensor network technology. Background technique [0002] The electrical connection parts of transformers, circuit breakers, isolating switches, bus bars, cable heads, etc. in high-voltage power equipment, after long-term current passes, due to climate change and equipment aging, the parts have poor contact, decreased insulation, and increased temperature. It will cause phase-to-phase short circuit, equipment damage, power supply interruption and other accidents. The temperature monitoring of high-voltage equipment is related to the reliable and safe operation of the entire system. [0003] Traditional inspection methods require manual inspections, and temperature data cannot be obtained in real time. Some existing wireless temperature measurement devices have realized the purposes of simple...
