Description

A kind of fire water box water level abnormality warning system

Technical field

The utility model relates to electronic monitoring warning system field, more relates to the reporting chain that a kind of fire equipments is monitored unusually, especially fire water box water level abnormality warning subsystem.

Background technology

The high speed development of urban economy, make the kind and the character of City Building (group) increasingly sophisticated, in building, road, uncertainty in the key elements such as water source also increases greatly, thereby the municipal public safety affairs (are comprised fire prevention, anti-bandit, medical care first aid etc.) strick precaution just more and more causes people's attention with the processing of reporting to the police, particularly need fire is carried out unit and the department such as the market of guard key at some, the restaurant, the hotel, the station, the warehouse, machine room, office, public place of entertainment etc., in case breaking out of fire and delay are reported to the police or the indefinite words of alarm condition, loss that disaster caused and baneful influence will be immeasurable.At present, most key units in domestic big or middle city and department all are equipped with automatic alarm and monitoring system at its emphasis fire prevention position, are used for the fire alarm monitoring of our unit and department.This type systematic mainly is made up of detection sensor and controlling alarm main frame, and acquisition sensor comprises detecting devicess such as cigarette sense, temperature sense and coal gas probe, and they are distributed in each condition of a fire control point.When detecting the condition of a fire, probe sends warning message to main control system, and main control system produces the warning executive routine.

But, these fire protection warning equipment are only monitored the fire-fighting dangerous situation and are reported to the police, in case after really dangerous situation taking place, still need be and be arranged on on-the-spot unit and department take place fire as market, restaurant, hotel, station, warehouse, machine room, office, public place of entertainment etc. fire fighting equipment facility and carry out the fire suppression activity of suing and labouring by fire fighter's equipment.Though these fire carry out the unit of guard key and department can regularly regularly detect and maintenance work being arranged on on-the-spot fire fighting equipment under the guidance of fire department, still can not guarantee during 2 are detected maintenance in the possibility that is not damaged of fire fighting equipment.In case these fire fighting equipments are damaged, will cause directly and seriously influence the work of putting out a fire to save life and property of the elimination of fire-fighting dangerous situation and fire.

The utility model content

Therefore, problem at above-mentioned existence, a kind of automatic inspection function that has is proposed, can be effectively, accurately to outage, fire fighting supply pond owe that water, hydraulic pressure are unusual, cable, motor abnormality, power supply facility are unusual etc., and the fire fighting equipment system failure is monitored in real time, guarantees that the unusual reporting chain of fire fighting equipment of the round-the-clock safe operation of fire fighting supply and system is very necessary.The technical scheme that the utility model proposes is a fire water box water level abnormality warning subsystem in the unusual reporting chain of this fire fighting equipment.

The utility model adopts following technical scheme:

Fire water box water level abnormality warning system of the present utility model comprises:

The power circuit of DC voltage-stabilizing is formed by power supply chip and external filter capacitor in one power circuit unit, and output electric property is connected in singlechip controller, wireless transmitting unit and detecting device port, and drive current is provided;

One singlechip controller is made up of singlechip chip and external crystal oscillating circuit and reset circuit, and the I/O port is electrically connected at wireless transmitting unit and detecting device port;

One wireless transmitting unit is made up of the antenna of radio transmitter and connection, is electrically connected at the I/O port of above-mentioned singlechip controller;

One detecting device port is formed the Signal Spacing transmission circuit by optical coupler, and output terminal is electrically connected at the I/O port of the singlechip controller of stating, and input end is electrically connected at a level sensor;

One level sensor is arranged in the fire water box, and output electric property is connected in above-mentioned detecting device port.

The technical solution adopted in the utility model, can cooperate with other subsystems that fire fighting equipment is circulated a notice of in the total system unusually, the fire equipments system failure and damage can be played precognition warning in advance, the serious consequence that the fire-fighting system fault is brought when avoiding fire-fighting to be eager to feed water, the Best Times of timely water effectively ensures national people's life, property safety in the time of guaranteeing the fire-fighting fire fighting.Fire water box water level abnormality warning system of the present utility model has automatic inspection function, can launch alerting signal to the cistern water level abnormal occurrence in real time by wireless transmitting system efficiently and accurately, guarantees the round-the-clock safe operation of waterworks for firefighting.
