Abstract:
Due to delayed alarms, lack of fire positioning, and lack of escape guidance, existing highrise fire alarm systems caused large casualties on the scene. Thus, this paper designs a fire alarm system with precise positioning, high-efficiency alarm, and intelligent escape guidance functions. It can be deployed in various areas of the building using the TXW8301-WiFi module, fire detector, and voice monolithic to form a node device, which can automatically detect the occurrence of a fire and broadcast the fire location and specific escape guidance routes on each floor as soon as possible, which can solve the problem of highrise buildings. Due to unknown and unclear escape routes, the long distance between buildings and many partitions causes the problem of missing the best time to escape. In addition to the automatic alarm guidance function, the system uses the channel monitoring video to remove smoke, add light and denoise, and perform pedestrian density detection based on deep learning algorithms. It can conduct multiple escape guidance according to the congestion of the escape channel, and finally, all the information will be displayed on the system’s main control interface to facilitate unified rescue command and minimize fire casualties.
