Embodiment Construction

[0038] In order to make the above objects, features and advantages of the present invention clearer and easier to understand, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] One of the core concepts of the embodiment of the present invention is that the front-end device adopts a sleep wake-up mechanism, and the communication board is in the state of "CAD-sleep-CAD-sleep" when it is not working, and uses continuous short packets to wake up the front-end when it needs to work equipment, so that the front-end equipment can handle the energy-saving and low-power consumption state, and can wake up in time when it needs to work; the time for a single short packet is 1.4 seconds, and the switching interval between sending 5 consecutive packets and packets is measured to be about 40ms; The purpose of this design is that after the gateway sends the previous two short packets, the communicati...

Abstract

The embodiment of the invention provides an implementation method of a wireless fire alarm system with a terminal wake-up function. The wireless fire alarm system comprises a gateway, front-end equipment comprising a communication board, and an alarm host connected with the gateway, the communication board realizes the following steps: enabling the communication board to monitor a network state according to a preset rule; when the wake-up packet is monitored, waking up the communication board; sending a wake-up response signal; sending alarm information; and after the communication is completed, returning to monitor the network state according to the preset rule. The front-end equipment adopts a dormancy awakening mechanism, the communication board is in a CAD-dormancy-CAD-dormancy state when the communication board does not work, and the front-end equipment is awakened by adopting continuous short packets when the communication board needs to work, so that the front-end equipment is in an energy-saving and low-power-consumption state and can be awakened in time when the communication board needs to work.

Description

technical field [0001] The invention relates to the technical field of fire terminal wake-up, in particular to a wireless fire alarm system with a terminal wake-up function and an implementation method. Background technique [0002] The automatic fire alarm system is composed of a trigger device, a fire alarm device, a linkage output device and other auxiliary function devices. The electrical signal is transmitted to the fire alarm controller, and at the same time, the entire floor is notified to evacuate in the form of sound or light. The controller records the location and time of the fire, so that people can find the fire in time and take effective measures in time to extinguish the initial fire. , minimizing the loss of life and property caused by fire, is a powerful tool for people to fight against fire. [0003] The fire alarm system has long been networked and communicated in a wired manner. In recent years, with the expiration of the fire alarm system in the early 1...
