Fire-fighting early warning system for new energy automobile charging pile

Abstract

The invention relates to a fire-fighting early warning system for a new energy automobile charging pile. The fire-fighting early warning system comprises a cloud platform, mobile terminals, a fire-fighting execution module, an edge computing equipment module and a temperature detector; the temperature detector is used for collecting temperature data near the charging pile; the edge computing equipment module is used for collecting the temperature data, uploading the temperature data to the cloud platform, predicting and judging the temperature, and executing the fire-fighting execution module if a fire disaster occurs; and the cloud platform is wirelessly connected with the plurality of mobile terminals, sends real-time temperature data to the mobile terminals, and sends alarm information to the mobile terminals after receiving an alarm signal. Compared with the prior art, the system can predict the future change trend of the temperature at the millisecond level, so that fire prevention and monitoring can be carried out at an ignition initial point, the battery of a new energy automobile is prevented from being burnt and exploded, and the damage is minimized; and meanwhile, early warning information and temperature information are pushed to the mobile terminals of users through the cloud platform, and the users are informed of the information in time.

Description

technical field [0001] The invention relates to the field of fire protection technology, in particular to a fire protection early warning system for charging piles of new energy vehicles. Background technique [0002] With the development of science and technology, the market demand for new energy vehicles is getting higher and higher. However, the safety problems of new energy vehicles occur from time to time, and automobile fires pose a serious threat to the safety of people's lives and property, and feasible solutions should be actively adopted to solve them. The batteries of new energy vehicles are generally made of ternary lithium batteries, lithium iron phosphate batteries and other materials. During the use of new energy vehicles, various external factors such as battery overcharge, battery overload, arcing at the interface, wear, collision, battery cell leakage, and internal overheating of the battery will cause the battery pack to fail. In this case, the exterior ...

AI Technical Summary

Problems solved by technology

When a new energy vehicle in this situation is charged in the parking area of ​​the charging pile, there will be a great potential safety hazard

Specifically, when an accident occurs, the new energy vehicle first catches fire from the inside of the internal battery pack, and will not produce a lot of smoke and high temperature. When the smoke and high temperature are generated, the new energy vehicle has already exploded. At that time, ordinary fire extinguishers could no longer prevent the spread of the fire, which made it difficult to control the fire and expand the damage.

As a result, the traditional smoke and temperature threshold early warning methods are unable to prevent and monitor new energy vehicles in the first place.
