The technical scheme that realizes the utility model object is as follows: a kind of divide-shut brake alarm set of control switch cubicle far away, the input of the first photoelectrical coupler U3 is connected to the output of control closing switch YH far away by resistance R 2, the input of the second photoelectrical coupler U4 is connected to the output of control separating brake switch YT far away by resistance R 3, the output of all photoelectrical couplers is parallel-connected to the signal input part of single-chip microcomputer U1; The first signal output of single-chip microcomputer U1 is connected to the base stage of triode Q1, and secondary signal output is connected to the control end of speech chip U2; The emitter of triode Q1, by resistance R 4 ground connection, is connected to working power after the coil of collector electrode series relay JD; The first normally opened contact JD-1 of relay J D is connected in control closing circuit far away, and the second normally opened contact JD-2 is connected in control sub-gate circuit far away; The output of speech chip U2 is connected to loud speaker.
Wherein, the model of described single-chip microcomputer U1 is LPC915, and the model of described speech chip U2 is ISD1820, and the model of described the first photoelectrical coupler U3 and the second photoelectrical coupler U4 is PC817.
The beneficial effects of the utility model are, before control switch cubicle far away carries out control far away point, closing operation, can play prompting sound, staff hears prompt tone, just knows that the sound having point, close a floodgate occurs, and rings and need not divert one's attention to watch out for the play of sending when switch divides, closes, keeping tensions down mood greatly, make work more wholwe-hearted, careful, increase work efficiency, reduce security incident.
Brief description of the drawings
Fig. 1 is that the control far away of the control switch cubicle far away of prior art divides, combined floodgate circuit diagram.
Fig. 2 is that relay normally open contact of the present utility model is connected in series to that control far away divides, the schematic diagram of combined floodgate circuit.
Fig. 3 is circuit diagram of the present utility model.
Fig. 4 is schematic appearance of the present utility model.
Embodiment
As shown in Figure 1, in the control switch cubicle far away of prior art, in the time that K switch K is placed in KKSH, contact 9,10 conductings complete closing by hand, and while being placed in KKST, contact 1,2 conductings complete manual brake separating.In the time that K switch K is placed in KKYK, contact 5,6 conductings, switch cubicle is in control state far away, receives that control far away has been ordered point, closing operation.Now, as receive control combined floodgate far away order, closing switch YH conducting, makes closing coil HQ conducting drive plug-in strip DL closure to complete closing operation; As receiving control separating brake far away order, separating brake switch YT conducting, makes switching winding TQ conducting drive plug-in strip DL to disconnect sub-switching operation.Can find out, when closing operation, the voltage that A is ordered can change because closing switch YH is closed; When sub-switching operation, C point voltage can change because separating brake switch YT is closed.
Fig. 3 is the circuit diagram of alarm set, the input of the first photoelectrical coupler U3 is connected to the output terminals A of control closing switch YH far away by resistance R 2, the input of the second photoelectrical coupler U4 is connected to the output C of control separating brake switch YT far away by resistance R 3, the output of all photoelectrical couplers is parallel-connected to signal input part 8 pin of single-chip microcomputer U1; First signal output 7 pin of single-chip microcomputer U1 are connected to the base stage of triode Q1, and secondary signal output 13 pin are connected to control end 2 pin of speech chip U2; The emitter of triode Q1, by resistance R 4 ground connection, is connected to working power after the coil of collector electrode series relay JD; The first normally opened contact JD-1 of relay J D is connected on (between A, B point) in control closing circuit far away, and the second normally opened contact JD-2 is connected on (between C, D point) in control sub-gate circuit far away, as shown in Figure 2; The output of speech chip U2 is connected to loud speaker LS.
The operation principle of alarm set is: far to control closing operation as example, and when control far away is closed a floodgate order while coming, YH junction closure, A point current potential rises, and after current-limiting resistance R2 and the isolation of photoelectrical coupler U3 photoelectricity are changed, is input to input 8 pin of single-chip microcomputer U1.The second output 13 pin output triggering signals of U1, to 2 pin of speech chip U2, are sent pre-stored sound in speech chip U2 by loudspeaker, alert notification Field Force, and the play that has point, closes a floodgate rings generation, performs psychological preparation.Single-chip microcomputer U1 inside starts delay circuit simultaneously, after approximately three seconds, and 7 pin output high potentials of the first output, triode Q1 conducting, relay J D continues and closes, normal opened contact JD-1, JD-2 displacement conducting, closing coil HQ conducting is closed a floodgate.In the 7 pin output high potentials of U1, start internal clocking circuit, after time delay in 4 seconds, no matter it is successfully no to close a floodgate, the circuit state that automatically restores to the original state, prepares for dividing next time, closing a floodgate.When separating brake, principle is with closing a floodgate, and only separating brake instruction is contact YT closure.
