Wireless networked type fire alarm system and method

Abstract

The invention provides a wireless networked type fire alarm system comprising an internet-of-things cloud platform, one or more controllers, one or more detectors, and one or more alarm devices. Eachcontroller is in wireless signal connection to at least one detector and / or one alarm device via an LPWAN. The detectors consist of wireless temperature detectors, wireless smoke detectors, wireless smoke-temperature composite detectors, and wireless manual alarm buttons. The alarm devices include wireless acousto-optic alarm devices. According to the invention, information including the temperature, smoke level and flammable gas concentration of the monitored area can be monitored; occurrence of a fire or explosion can be prevented timely; and a fire can be discovered timely and thus alarmingis carried out timely. On the basis of the extremely-low power consumption design, a low-power-consumption state is set in actual application and thus power consumption is reduced. The MCU module isused for realizing real-time low-power prediction and thus power is provided for the detectors and the alarm devices effectively.

Description

technical field [0001] The invention relates to the field of fire monitoring, in particular to a wireless networked fire alarm system and method. Background technique [0002] With the development of the national economy and the improvement of people's living standards, the height and breadth of modern buildings continue to expand. For independent areas, such as large warehouses, hotels, entertainment venues, collective dormitories, public rental housing, etc. Among them, building fire protection facilities have become an important part of construction engineering. In the case of family residences, rental houses, and small and micro places, where there are many buildings, densely populated, wide-ranging, and highly mobile, and most of the houses are decorated with flammable materials, and the owners have weak safety concerns and no clear management rights and responsibilities Division and other aspects lead to omissions and great hidden dangers in fire safety and supervisio...

AI Technical Summary

Problems solved by technology

[0004] Similar products currently on the market, there are two types of wired alarm methods and independent alarm methods; the traditional wired method has an alarm system composed of networked smoke detectors, temperature detectors, smoke-temperature composite detectors, etc., because the installation of the system is troublesome, The amount of construction is large, the cost of construction and maintenance is high, and maintenance is difficult. It is very difficult to promote it to the whole people, especially when it is not easy to wire or damage the building.

The traditional independent alarm method is an alarm system composed of independent smoke, temperature, and smoke-temperature composite detectors. Except for factors such as high power consumption that requires external power supply, short transmission distance, limited communication resources, and high cost, it is silent. Optical linkage function, not to mention multiple sound and light linkage alarm functions, and no special control center. When working independently, the alarm sound cannot be heard even 200m-300m away from the door, which is not suitable for promotion in the whole field
