Description

Technical Field

[0001] The utility model relates to the technical field of fire alarm equipment, and specifically relates to a fire recognition device. Background Art

[0002] With the continuous acceleration of the urbanization process and the continuous growth of the population, the population density has increased, making the building structures complex and diverse. The traditional manual patrol inspection method seems inadequate and is likely to overlook some buildings in the corners. When a fire occurs, an effective response cannot be made in a timely manner, which will pose a huge threat to people's lives and property safety. In this situation, to improve the prevention ability and handling efficiency of fire accidents and provide timely and accurate fire warning information, it is necessary to quickly develop a fire recognition device to deal with sudden fire situations.

[0003] To achieve real-time monitoring of fires, traditional fire recognition generally involves installing an AI recognition system in the cloud. The video data collected by the camera is transmitted to the cloud for analysis and recognition. However, the cloud is only suitable for recognizing a large number of cameras at close range. When facing individual users or individual warehouses in remote areas, the practicality of the cloud will be greatly reduced. Therefore, the edge computing box, a kind of fire recognition device, has emerged in response to the demand.

[0004] In the prior art, after individual users or warehouses in remote areas install fire recognition devices, due to the small number, regular maintenance is inevitably lacking, so that a large amount of dust will accumulate on the fire recognition devices. When the dust enters the connection part of the fire recognition device, it will cause poor contact of the fire recognition device, thereby affecting the sensitivity of the fire recognition device.
