Combined type wireless building fire alarm device

Abstract

The invention relates to a combined type wireless building fire alarm device, which comprises a main controller unit, a CO concentration monitoring unit, a smoke concentration monitoring unit, an environmental temperature monitoring unit, an acousto-optical early warning and alarm unit and a status indicating unit, wherein the CO concentration monitoring unit, the smoke concentration monitoring unit, the environmental temperature monitoring unit, the acousto-optical early warning and alarm unit and the status indicating unit are respectively connected with the main controller unit. The combined type wireless building fire alarm device combines wireless sensor network technology of internet of things and fire signal intelligent detection and processing technology, adopts a Zigbee wireless ad hoc network mode to be connected into a building fire alarm system network without manual configuration, adopts a plurality of sensing units integrating temperature sensing, smoke sensing and gas sensing, and can collect three signals of temperature, smoke concentration and CO gas concentration. After neural network modeling analysis of a sensor, the combined type wireless building fire alarm device comprehensively judges whether a fire breaks out, effectively improves promptness and reliability of fire alarms, reduces false report and missing report rate of a system, improves stability of the system, and has the advantages of being easy to install, rapid, cheap, free of wiring and strong in adaptability of function changes.

Description

technical field [0001] The invention relates to a fire alarm device, in particular to a composite wireless building fire alarm device. Background technique [0002] Fire is a disaster with high frequency, often causing huge casualties and property losses. In recent years, with the rapid development of the application of intelligent building technology, the demand for fire alarm systems in the commercial market has continued to grow. At present, the fire alarm system based on the wired intelligent bus system distributed computer system is mainly used, although it is installed in the system. On the one hand, it is much more convenient than in the past, but there are still problems such as long construction period, high investment, difficult maintenance, missed reporting, and high false alarm rate. The installation cost of the wired system accounts for about 33% to 70% of the total equipment cost. Therefore, the existing wire-based fire alarm monitoring system can no longer me...
