Line fault self-diagnosis system and method suitable for fire alarm

Abstract

The invention discloses a line fault self-diagnosis system and method suitable for fire alarm, and belongs to the technical field of fire alarm systems. In order to solve the problems that various fire-fighting facilities used in a building in the prior art need to be manually inspected regularly to ensure that the fire-fighting facilities can cope with some sudden fire behaviors, but only the surface state and the aging condition of the devices can be detected in a manual inspection mode, and an internal control circuit cannot be detected, the invention provides a fire-fighting equipment inspection system. A self-checking system of fire-fighting equipment in a whole building is set by means of a fire alarm controller, the self-checking is performed every day in an ideal value state, the self-checking time period is preset to be 8: 00-9: 00 in the morning or 12: 00-1: 00 at noon as far as possible, the two time periods are not in the peak period of electricity utilization, and the number of people in the building is large under the normal condition. The situation that some emergencies emerge in the self-checking process of the system, and when the system cannot make a response in the first time, manual operation can be replaced is avoided.

Description

technical field [0001] The invention relates to the technical field of fire alarm systems, in particular to a line fault self-diagnosis system and method suitable for fire alarms. 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. , to minimize the loss of life and property caused by fire, is a powerful tool for people to fight against fire, and the fire linkage equipment is the executive component of the automatic fire alarm system, after the fire control room receives the fire alarm information, it should be able to automatica...

Problems solved by technology

[0003] However, all the fire-fighting facilities used in the existing buildings need to be manually inspected regularly to ensure that they can deal with some sudden fires, but the manual inspection method can only detect the damage of the devices The surface state and aging conditions cannot be detected for the internal control circuit; therefore, it does not meet the existing needs. For this, we propose a line fault self-diagnosis system and method suitable for fire alarms
