Failure detection instrument for intelligent inspection of fire-fighting inspection cabinet

Abstract

The invention relates to a failure detection instrument for intelligent inspection of a fire-fighting inspection cabinet. The failure detection instrument comprises a single chip microcomputer, a three-phase undervoltage / overvoltage detection module used for detecting that whether the power circuit of the fire-fighting inspection cabinet is undervoltage / overvoltage or not and for sending failure signals to the single chip microcomputer, a three-phase overcurrent / overload detection module used for detecting that whether the load is overcurrent / overload or not and for sending failure signals to the single chip microcomputer, a circuit current leakage detection module used for outputting signals to the single chip microcomputer when leaking current of a load circuit exceeds a setting valve, and an external inspection module which can stop inspection when the single chip microcomputer receives a failure signal and outputs the detected failure to an external text to record the name and the time of the failure and give an acousto-optic alarm; when a fire signal is received during inspection, the inspection process of the single chip microcomputer is stopped, and a fire extinguishing process is started to achieve the function of fire fighting priority. The failure detection instrument can accomplish variable-frequency intelligent low-velocity automatic inspection control of a fire pump and a sprinkle pump and has the functions of giving out sound and light alarms and memorizing failures.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment detection, in particular to an intelligent inspection fault detector for a fire-fighting inspection cabinet. Background technique [0002] With the rapid development of cities, various buildings are increasing day by day, and various flammable materials can be seen everywhere in the buildings, which greatly increases the possibility of fire. Although every building is equipped with a fire extinguishing system, experience and lessons have proved that the success of fire fighting depends mainly on whether the fire water supply equipment is in good condition. The fire pump is an important part of the water fire extinguishing system. It is characterized in that it is not used for a long time at ordinary times, and once it is used, it must play a 100% role. Due to the long-term idle state and the humid environment of the pump room, it is easy to break the pump shaft of the fire pump. A...

The fire pump is an important part of the water fire extinguishing system. Its characteristic is that it is not used for a long time at ordinary times. Once it is used, it will play a 100% role. Due to the long-term idle state and the humid environment of the pump room, it is easy to break the pump shaft of the fire pump. and impeller corrosion, rust phenomenon, so that when a fire occurs, the fire pump cannot operate normally, unable to extinguish the fire and protect the lives and property safety of the people
