Three) on-line customer's monitoring and warning
On ordinary meaning, on-line customer's alarm signal mainly refers to fire, fault and the supervision action alarm signal that its automatic fire alarm subsystem is sent. Its generation is because fire assembly action or running status change, and produces triggering signal by itself or its monitoring and controlling module, by patrolling and examining, has sent warning by the supervision such as fire alarm control unit and linkage controller alarm controller. For the fire-fighting assembly of concrete warning, its running status has uniqueness, but for the fire-fighting reliability unit by fire-fighting module composition and fire-fighting subsystem, the running status of its assembly may comprise multiple running status, as the indicator lamp that the shielding of a fire alarm control unit, fault and supervision are reported to the police is all lighted, sent again fire alarm signal, the duty of this automatic fire alarm subsystem has comprised fire alarm state (fire alarm is preferential); Monitor alarm condition, fault-alarming state and delay state (shielding). Based on GB26875-2011 standard, on-line customer's information that Surveillance center can obtain mainly contains following five parts:
1, the fire alarm information of on-line customer's fire detection alarm system;
2, building fire protection facility running state information;
3, the fire confirmation of manually reporting to the police;
4, operator on duty's information whether on duty;
5, the machine fault alarm information of user profile transmitting device.
At this, what running state information was general monitors that by automatic fire alarm subsystem control module and fire protection linkage control equipment send, and are dealt into Surveillance center by user profile transmitting device. Stateful Inspection is divided into component faults supervision and device action monitors two kinds, and supervision alarm signal has been indicated three kinds of duties of monitoring equipment or assembly: normal monitoring state, actuation of an alarm state and malfunction.

2, the alarm signal of the system failure: the fault of main electric fault, standby electric fault, system bus fault, interlock power failure, 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 alarm signal, cistern water level deficiency failure alarm signal;
4, the wrong report fire alarm through confirming or supervision module wrong report fault-signal.
Existing processing method, just add up and sort out receiving the alarm signal of fault, and by supervision control signal be defined as monitor alarm condition process 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 alarm 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 fire-fighting subsystem inner and relevant to the fire-fighting subsystem at its place to carry out synthetic determination, analyze the correlation of these failure alarm signals. Comprise two levels: on system task level, belong to the correlation between different subsystems, need other subsystem that material, energy input and control signal are provided as the task of a fire-fighting subsystem or assembly completes; Another level is a fire-fighting subsystem inside, and faulty components is correlation 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 fault message.
Taking automatic sprinkling fire-extinguishing subsystem as example, the fault alarm correlation 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 for fire fighting supply provide monitor and enabling signal, its fault has also caused the partial fault of fire fighting supply function and automatic sprinkling fire-extinguishing function.
