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...
