Abstract

The invention discloses a cable fire prediction and monitoring system and method in a substation. The system includes: a cable trench fire detection device and a closed facility detection device; a fire monitoring system server for receiving the cable trench fire detection device and the closed facility detection device The measurement data sent out; the measurement data of the same type of sensors are fused through an adaptive weighted fusion estimation algorithm to obtain the minimum error value of each type of sensor; the fire probability is used as a verification for decision-making, and D‑S evidence theory technology is used to analyze fire The judgment is made based on the trend, and the fire alarm information is given based on the preset judgment rules. The invention can solve the technical problems existing in the prior art when a single sensor is used to monitor fire signals: poor anti-interference ability, easy to be affected by environmental interference and noise, and high probability of false alarm and false alarm.

Description

technical field [0001] The invention relates to the technical field of cable fire early warning, in particular to a cable fire prediction and monitoring system and method in a substation. Background technique [0002] Fire is a violent chemical reaction between combustibles and combustion aids, usually accompanied by physical and chemical phenomena of luminescence and heat generation, and aerosols, smoke, light, heat and combustion waves are generated during the process; the current fire detection It is to determine the fire process through the measurement and analysis of the above parameters. [0003] Human beings have experienced more than 100 years of history in the detection and research of fire. As early as 1847, the United States developed the world's first transmission device for urban fire alarms. In 1890, the United Kingdom successfully developed a temperature-sensitive fire detector. In the next half a century, the temperature-sensitive fire detector has been occu...
