Early warning method and device for early fire of cable channel, early warning monitoring platform and storage medium

Abstract

The invention relates to the technical field of cable fire prevention, in particular to an early warning method and device for early fire of a cable channel, an early warning monitoring platform and a storage medium. The method comprises the following steps that: a plurality of infrared temperature measurement areas are selected according to a cable layout map in a cable channel, a CO concentration detection device, a CO2 concentration detection device, an O2 concentration detection device and a flue gas concentration detection device are installed in the cable channel, and a plurality of temperature measurement points are arranged at A-phase, B-phase and C-phase joints of a cable; an early warning threshold and an alarm threshold (greater than the early warning threshold) of the concentration of each device are set, data of each device is acquired and whether the data reach the threshold or not is judged, and if the data reach the threshold, first early warning information is sent out; and the data is continuously monitored, if the data increases in an accelerated manner, an early warning is given to indicate that the fire hazard increases, and if the data decreases, it is indicated that the fire hazard decreases. The invention further provides an emergency treatment scheme linking fire early warning with fire extinguishing, and the effectiveness of the cable channel early fire early warning method is fully exerted.

Description

technical field [0001] The invention relates to the technical field of cable fire prevention, in particular to an early fire early warning method and device for a cable channel, an early warning monitoring platform and a storage medium. Background technique [0002] Because the cable channel is narrow and long and closed, it is difficult to find and eliminate fire hazards. When a fire occurs, it is easy to cause the loss of the section and cause a large-scale power outage. The study found that the fires caused by the current overload of the disaster source and the aging of the insulation layer that caused the fire in the cable channel accounted for a large proportion of the cable fires caused by the heating of the cable connection. In addition, after fires caused by dust, oil, flammables, welding sparks and other equipment failures, fire accidents outside the cable also occur from time to time. At this time, the cable connection is easily affected and becomes a dangerous poi...

Problems solved by technology

In the current engineering practice, there is still considerable controversy among designers in the industry regarding the selection of the type of automatic fire extinguishing system, and there is no clear implementation plan for the fire extinguishing system. In addition, fixed fire detection devices are generally installed at a certain node of the cable channel. The fire detection range is limited, and there are detection blind spots; the power cable channel has a small space, a long and narrow structure, and the environment is relatively complex, communication is inconvenient, and the early warning timeliness of the fire detection device is poor
