Description

Technical Field

[0001] The utility model relates to the technical field of fire smoke identification and alarm devices, in particular to a fire smoke intelligent identification and automatic alarm device. Background Art

[0002] With the rapid development of urbanization, the density of commercial and residential areas continues to increase, and the risk of fire also increases accordingly. In order to detect the occurrence of fire and promptly report the fire, corresponding detection alarms are usually installed inside the building. Traditional fire detection alarms mainly rely on smoke detectors and temperature sensors. Smoke detectors are used to detect smoke, and temperature sensors are used for temperature detection. Once smoke is detected or a rise in temperature is detected, the alarm will be controlled to sound an alarm.

[0003] However, smoke detectors and temperature sensor-type detection alarms often have problems with false alarms or missed alarms in complex environments. Due to their low sensitivity and high false alarm rate, they cannot meet the growing fire safety needs and cannot effectively protect people’s lives and property.

[0004] In order to achieve the effect of intelligent fire protection, intelligent smoke recognition and automatic alarm devices are usually used to perform intelligent recognition and alarm operations. This type of intelligent smoke recognition and automatic alarm device generally collects smoke data through a data acquisition module, uses an intelligent recognition module to identify smoke information, uses an alarm module to sound an alarm, and uses a communication module to transmit the alarm information to the corresponding background.

[0005] However, when this type of smoke intelligent identification and automatic alarm device is used, it uses a data acquisition module for collection operations, and the data acquisition module is generally fixed in a specific position, such as on a building wall. Due to poor indoor ventilation, relying solely on indoor air flow is not conducive to timely transporting smoke to the data acquisition module for data collection, which affects the timeliness of the alarm and brings inconvenience to the user. In view of this, we propose a fire smoke intelligent identification and automatic alarm device. Utility Model Content
