Indoor smoke alarm system and alarm control method thereof

Abstract

The present invention relates to an indoor smoke alarm system and an alarm control method thereof, belonging to the technical field of smoke alarm. The system comprises a plurality of indoor alarm devices, a LPWAN station and a remote alarm device, the indoor alarm devices are distributed in a floor or a room, the LPWAN station and the remote alarm device are distributed at the control center, each indoor alarm device comprises one smoke induction device, each smoke induction device comprises one smoke sensing module, one power module and one LPWAN module; the power module in each smoke induction device is connected with the smoke sensing module and the LPWAN module thereof, and the smoke sensing module is connected with the LPWAN module; and the LPWAN module in each smoke induction deviceis connected with the LPWAN station. A mode of transmission of smoke concentration data through a cable in a traditional indoor smoke alarm system is improved to a mode of transmission of the smoke concentration data through the LPWAN modules so as to improve the intelligent degree, the network degree and the module connection mode reliability, and it is avoid that the burnout of the cable causessystem faults to improve the reliability of the system.

Description

technical field [0001] The invention relates to the technical field of smoke alarms, in particular to an indoor smoke alarm system and an alarm control method thereof. Background technique [0002] With the rapid development of my country's economy, the number of high-rise buildings in cities is increasing, and the building density is also increasing. Once a fire breaks out in a high-rise building, evacuation and rescue will become very difficult. If the fire is not dealt with in time, it will inevitably cause casualties or property damage. The indoor smoke alarm system can timely alarm the fire, therefore, the indoor smoke alarm system in high-rise buildings plays a very important role. [0003] For the indoor smoke alarm system widely used at present, the network cable is used to connect the smoke sensor to the remote alarm device. The traditional indoor smoke alarm system has the disadvantages of low intelligence, low network and low reliability of component connection. ...

AI Technical Summary

Problems solved by technology

Traditional indoor smoke alarm systems have disadvantages such as low intelligence, low networking and low reliability of component connection methods.

In addition, the maximum heat-resistant temperature of the network cable of the current indoor smoke alarm system is 250°C, while the minimum temperature of the flame is 800°C. It is easy to cause system failure due to the blown network cable, resulting in the failure of the indoor smoke alarm system.
