Description of drawings:
Fig. 1 is the utility model electrical block diagram.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, this device comprises that 4 group relaies output control, 4 groups of input signal detection, a urgent output control circuit, a RS485 interface circuit, 2 operation push-buttons, 8 status indicator lamps and 2 time-delays show charactron.
4 group relaies comprise K1, K2, K3 and K4.K1 is single fire alarm relay, and K2 is for spraying relay, and K3 is compound fire alarm relay, and K4 is compound fire alarm time-delay relay.One end of the coil of K1, K2, K3 and K4 links to each other with the 24V positive source, and the other end of coil links to each other with the output of optocoupler D3 control respectively, and this end of the coil of K4 also links to each other with the end of emergency start button TQ.When this subregion had any fire alarm, cpu chip D1 controlled 1, the 2 pin conductings of optocoupler D3 by delivery outlet P14, thereby made the K1 action; When this subregion had pyrotechnics police and warm fire alarm simultaneously, cpu chip D1 controlled 5, the 6 pin conductings of optocoupler D3 by delivery outlet P16, thereby made the K3 action; When delay time arrived, cpu chip D1 controlled 7, the 8 pin conductings of optocoupler D3 by delivery outlet P17, thereby made the K4 action; When input detected the sprinkling signal, cpu chip D1 controlled 3, the 4 pin conductings of optocoupler D3 by delivery outlet P15, thereby made the K2 action.
4 groups of input signal detection comprise that control valve broken string, sprinkling, on-the-spot startup, scene stop.The test side of control valve broken string links to each other with the anode of comparator D5 by R12, also comprises resistance R 13, R14, R15.When the connecting line with control valve broke, the anode input voltage of comparator D5 was higher than the negative terminal input voltage, and comparator D5 is output as high level, and 1,2 pin of optocoupler D4 end, and 16 pin of optocoupler D4 are output as high level, thereby detect malfunction.The test side of sprinkling, on-the-spot startup, on-the-spot stop signal links to each other with the input negative terminal of optocoupler D4 respectively, and link to each other with the input anode of D4 respectively with R11 by resistance R 9, R10, when these signals are effective, the diode current flow of optocoupler D4 input, the corresponding output end that causes optocoupler D4 is a low level, thereby detects corresponding signal condition.
The end of emergency start button TQ links to each other with the 24V power cathode, and the other end links to each other with an end of the coil of relay K 4.If be in a state of emergency, need start K4 immediately and make the gas extinguishing system action, can realize that emergency start button TQ is the self-locking type button by pressing emergency start button TQ.When this button was pressed, K4 action realized without time-delay and the function of emergency start.
The RS485 interface circuit mainly comprises a RS485 interface chip D2, the A of D2, B end links to each other with corresponding A, the B end of fire alarm control unit through resistance R 5, R6, carry out communication with controller, can receive fire alarm information and linkage status that controller is sent, also can return the various states of this device to controller.
2 operation push-buttons are start key S1, stop key S2, are non-self-locking button.One end of two buttons with link to each other, and link to each other with the negative pole of 5V power supply, the other end links to each other with defeated population P42, the P43 of cpu chip D1 respectively.When button was pressed, the corresponding input port of cpu chip D1 detected low level, carries out corresponding keypress function again.
The end that 8 status indicator lamps and 2 time-delays show charactrons with link to each other after the delivery outlet P2 of cpu chip D1 drives by triode, the other end of eight light emitting diodes and two charactrons links to each other with delivery outlet P10, P11, the P12 of cpu chip D1 respectively, carries out timesharing by D1 by software control and refreshes.8 indicator lamps are respectively pyrotechnics police, warm fire alarm, time-delay, startup, sprinkling, fault, on-the-spot start and the scene stops, and when device detects corresponding state and exists, promptly light corresponding indicator lamp; When K4 is in the time-delay state, on the charactron display delayed countdown time, when delay time arrives, the K4 action, charactron extinguishes.
