Description

Technical Field

[0001] The utility model relates to the technical field of fire monitoring, in particular to an image-type composite fire detector based on temperature, smoke and flame. Background Art

[0002] Fire is one of the most common threats to public safety. In the early stages of a fire, the flames are small and low, producing little smoke and making it difficult for people to detect. As the flames continue to spread and spread to other furniture, the fire grows, rapidly increasing the indoor temperature and producing large amounts of smoke, causing serious harm to people. Therefore, to reduce the risk of fires and protect people's lives and property, fire detectors are needed that can monitor the environment in real time and issue prompt alarms when anomalies are detected.

[0003] Currently, common fire detectors include photoelectric smoke detectors and ionization smoke detectors. Photoelectric smoke detectors generate signals through the light beam received by the photosensor on the detector for detection. When there is smoke in the ambient air, the smoke particles will scatter more light beams onto the photosensor, thereby alarming. Ionization smoke detectors alarm by detecting the ionization conditions in the air.

[0004] However, at present, this type of detector has the problem of a single detection parameter. Relying on a single data to determine a fire is prone to missed reports. When the smoke production is low in the early stage of combustion, there are fewer smoke particles in the air, so there are fewer light beams scattered to the photosensitive elements of the smoke detector, and the ionization in the air is also weak. Therefore, it is difficult to monitor the occurrence of a fire in the early stage of combustion, resulting in missing the best time to extinguish the fire. Utility Model Content
