Multiplex circuit as shown in Figure 2, this circuit is the key point of decision multichannel detection speed, the utility model makes detection speed improve three orders of magnitude than conventional detection speed.By the sampling comparator circuit, signal after relatively differentiating, deliver to multiplex circuit, central controller is under the master routine monitoring, carry out full column scan, single scan range is 64 the tunnel, send " 1 " signal entirely by master routine to data bus, gating SMOKE1 passes through 74LS244, each row is low level behind 74LS273 and the SN75452B, does not all have fire and fault-signal as full row, then to send the signal of data bus back to also be complete " 1 " signal to the 74LS244 of gating PATROL1, by master routine relatively after as can be known, surely belong to normal operating conditions, then change another module over to and scan; When fire and fault-signal, then change branch column scan and subarea-scanning over to, and carry out multi-retrieving by full column scan, confirm as fire signal after, then output order is given printer, clock display circuit, sound light alarming circuit, LED display matrix circuit.Printer promptly writes down the time of catching fire, place, code name on duty, clock display circuit and light-emitting diode display are the dual demonstration place that catches fire, through regularly inquiry, (generalized case is 4～8 minutes from smog to Hong the combustion time) still has former fire signal at man-machine affirmation fire signal and after delaying time several minutes, then central controller promptly sends instruction, exports corresponding control contact and uses for the fire-fighting system interlock.The purpose of time-delay is in order to prevent the secondary man-made disaster, when fire after bud is eliminated, promptly manually promptly reset by central control board.After fire signal disappeared, system still can automatically return to the survey state that normally patrols, and can distinguish normal, fault, three kinds of signals of fire simultaneously to arbitrary loop.When several loops several unlike signal occurs simultaneously, microcomputer all can be discerned, and can repeat to show and record multi-region fire and failure condition, when having signal, arbitrary loop should in time confirm and get rid of, otherwise keep and time, zone and loop that tracer signal took place number, cancel message can be said the word by Central Control Room and realize always.
Multichannel output control circuit shown in Figure 2, under the supervision of master routine, if several measures such as startup automatically, delayed startup, manual emergency start and manual emergency resets, the scope of control comprise smoke control system, broadcasting and evacuate aspects such as command system, warning system, fire-fighting electric current.This circuit data bus DB and control bus CB direct and microcomputer link up with, and send corresponding control programs according to the requirement of high building fire fighting standard by master routine, and this system has following responding ability:
1) stops preventing valve and receiving its feedback signal on air conditioner, pressure fan and the pipeline with warning position domain of dependence by the subregion of ventilation and air conditioning system.
2) start with induced-draft fan (the comprising positive pressure fan) Smoke-proof hanging wall and the exhaust opening (or valve) on the pipeline of warning domain of dependence and receive its feedback signal.
3) close electronic fire-proof door, the fire resisting shutter at relevant position and receive its feedback signal.
4) cut off non-fire-fighting power supply by fire compartment and evacuation orders.
5) force elevator all descending, except that Fire lift, Lift out of use for other in bottom (comprising Fire lift, passenger lift and goods elevator) for off-position.
6) according to fire compartment and floor evacuation orders, connect fire alarm installation or accident broadcast system, open catch fire layer and relevant layers broadcasting and induce and evacuate broadcasting.
7) can keep with the communication facilities of special use in easy communications and liaison system.
8) on the central control board of Central Control Room, have the running status indication and the Presentation Function of corresponding fire extinguishing system.
The responding ability of above output interface matches with detecting feeder number and area dividing, by the scale of engineering and function and the configuration needs that required feeder number decides output interface and the control function that is reached of area dividing.Reach the purpose of monitoring as all configurable corresponding output modules of a few items in the above control program of need and establishment corresponding control programs.
Central control board also has the alternating current 220V dual power supply automatic switching device and 24V float type direct supply, can supply the working current of the fire fighting devicies such as water flow indicator of exhaust opening (valve) automatic sprinkler fire-extinguishing system.
