Abstract

The invention relates to a sulfur hexafluoride gas monitoring system based on ZigBee wireless technology. Wired transmission is adopted in current monitoring, which has wiring difficulty and high cost. The system comprises a plurality of sulfur hexafluoride monitoring nodes in a monitoring area and a data base station, wherein the sulfur hexafluoride monitoring node is based on the ZigBee wireless technology, and comprises a microprocessor module, a node ZigBee radio frequency chip, a power supply management module and a sulfur hexafluoride gas collection module; and the data base station adopts an advanced RISC machine (ARM) processor structure, and comprises a base station ZigBee radio frequency chip and a general packet radio service (GPRS) transmission module. The system can be used for collecting sulfur hexafluoride and temperature, and has the advantages of high data communication capability and wide network coverage range.

Description

technical field [0001] The invention belongs to the technical field of automatic monitoring and the field of wireless communication, and relates to a harmful gas monitoring system based on a wireless sensor network. Background technique [0002] In the power system, sulfur hexafluoride gas is used as the insulating gas of the high voltage switch. Sulfur hexafluoride is a colorless, odorless gas heavier than air. When sulfur hexafluoride is mixed with oxygen, it will produce toxic and harmful gases, which will endanger the lives of workers. In order to prevent accidents and ensure the personal safety of operators in production, it is necessary to monitor the concentration of sulfur hexafluoride in the environment online. The traditional monitoring method is laboratory measurement. This method requires manual sampling and measurement in the laboratory. It has low sensitivity, complicated operation, and long time consumption, and is not suitable for real-time online measuremen...
