Wireless independent fire alarm system

Abstract

The invention relates to a wireless independent fire alarming device, which comprises a plurality of wireless inductive probes and monitors. The wireless independent fire alarming device is characterized in that: the wireless inductive probes can communicate with each other and can wirelessly send collected alarm signals to the monitors; the wireless inductive probes respectively comprise a fire detecting module, a signal conversion module, a wireless transceiver module (a), an amplifier module and a transceiver antenna; the fire detecting module has such functions as transmitting, receiving, and processing of fire alarm signals and realizing acousto-optic alarming; the monitors comprise a central controller; the central controller is connected with a clock module, a memory, a wireless transceiver module (b) and a display or keystroke module for human-computer interaction; and the wireless transceiver module (b) is connected with the amplifier module and the transceiver antenna in sequence. Through the wireless transmission function, the device not only simplifies a system circuit but also realizes the remote monitoring and the humanizing fire alarm.

Description

technical field [0001] The invention relates to the field of wireless control, in particular to a wireless independent fire alarm device. Background technique [0002] The existing fire alarm system adopts wired technology to set up fire sensor network. The disadvantages of this type of solution are long installation period, poor expansion performance, cumbersome wiring, and complicated debugging. In addition, due to the use of hard-wired connections, the lines are prone to aging or corrosion, rat bites, and wear, resulting in a high failure rate and a high rate of false alarms. The wireless fire sensor network constructed by wireless transmission can just avoid these problems. Relatively speaking, the wireless method is more flexible, avoiding the trouble of rewiring, the infrastructure of the network no longer needs to be buried in the ground or hidden in the wall, and the wireless network can adapt to the needs of movement or change. [0003] There are two main types o...

Problems solved by technology

The disadvantage is that the communication distance is short, the coverage is small, and the reliability is poor. Although the transmission distance can be increased by adding a wireless relay, once the relay fails, all communications will be interrupted.

Except for the main transceiver, other wireless transceiver nodes cannot communicate with each other, that is, they do not have network functions, so the communication quality cannot be guaranteed, and it is not suitable for fire alarm systems
