On-line customer's failure alarm signal mainly comprises four kinds:
1, position failure alarm signal, on-the-spot addressed location fault in indication fire alarm subsystem;
2, the alerting signal of the system failure: the fault of main electric fault, standby electric fault, system bus fault, interlock power fail, alarm host machine machine halt trouble and user profile transmitting device self etc.;
3, assembly or fire fighting equipment failure alarm signal, by monitoring module and Sensor monitoring, the failure alarm signal sending through user profile transmitting device.As the signal valve in automatic water sprinkler systme closes valve alerting signal, cistern water level deficiency failure alarm signal;
4, the wrong report fire alarm through confirming or supervision module wrong report fault-signal.
Existing disposal route, just to receiving the alerting signal of fault, add up and sort out, and supervision control signal is defined as and monitors that alarm condition processes separately, in fact, in above-mentioned four kinds of fault-signals, 1,2, be alarm unit faults itself in 4 three kind of situation, 3 of situations, for monitoring action alerting signal, are the fault-signal of its monitored object.
According to existing failure alarm signal and check result, judge whether this fire-fighting assembly fault has really occurred, also need the running status of the inner and relevant fire-fighting subsystem of the fire-fighting subsystem at its place to carry out synthetic determination, analyze the correlativity of these failure alarm signals.Comprise two levels: on system task level, belong to the correlativity between different subsystems, as the task of a fire-fighting subsystem or assembly completes, need other subsystem that material, energy input and control signal are provided; Another level is inner a fire-fighting subsystem, and faulty components is correlativity between reliability unit inside and different fire-fighting reliability unit, and in wet alarm valve unit, water pipe stops up the supervision fault of the pressure switch causing.With this, reject the fault-signal that dereferenced produces, determine real failure message.
Take automatic sprinkling fire-extinguishing subsystem as example, and the fault alarm correlativity of its different fire-fighting subsystems is as shown in table 1:
In table 1, fire-fighting power supply subsystem provides electric power for fire fighting supply, its fault has directly caused fire fighting supply functional fault and automatic sprinkling fire-extinguishing functional fault, fire alarm system monitors and enabling signal for fire fighting supply provides, and its fault has also caused the partial fault of fire fighting supply function and automatic sprinkling fire-extinguishing function.
