Fire warning system and method for underground power distribution network

Abstract

The invention provides a fire warning system and method for an underground power distribution network. The system comprises an equipment temperature sensing module, a cable fire detection module, a video fire identification module, and an upper computer. The equipment temperature sensing module is used for measuring the temperature of underground power distribution equipment. The cable fire detection module is used for carrying out fire detection on an underground power distribution cable. The video fire identification module is used for monitoring an area where a fire is likely to happen in an underground power distribution network in real time and extracting video information of a key area for intelligent identification and analysis. The upper computer is in communication connection withthe three modules, and is used for receiving information collected by the three modules for integrated analysis and sending an emergency disposal decision. Double fire detection of the power distribution equipment and the power distribution cable is realized. The key data of the key area is collected and analyzed through real-time video collection, and warning information is sent in time. Therefore, the fire warning capability of the underground power distribution network is greatly improved, and the probability of fire is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of fire detection, in particular to an underground distribution network fire early warning system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] The danger and harm of underground space fires are much greater than those of above-ground building fires. The underground space generally has few exits, the space is relatively airtight, it is difficult to determine the ignition point of the fire, and it is very difficult to rescue in the event of a fire. Once a fire breaks out, it is very easy to cause mass deaths and injuries and serious property losses. However, limited by the existing technical capabilities, there are still deficiencies in the early detection of fires in underground spaces, especially in large underground spaces. Technically, it is cu...

AI Technical Summary

Problems solved by technology

Underground space generally has few exits, the space is relatively airtight, it is difficult to determine the ignition point of the fire, and it is very difficult to rescue in the event of a fire. Once a fire breaks out, it is very easy to cause mass death and mass injury and serious property loss

However, limited by the existing technical capabilities, there are still deficiencies in the early detection of fires in underground spaces, especially in large underground spaces. Technically, it is currently impossible to realize the early positioning of fires. good time

[0004] The inventor found in the research that with the continuous development and utilization of underground space, more and more underground distribution networks have been put into use. During the high-load operation of the distribution network, a large amount of heat will be generated, which can easily cause fires, but At present, there is no fire warning method for the underground distribution network. Once a fire occurs in the underground distribution network, it will cause the distribution equipment to explode, which will easily cause a huge catastrophic accident.
