Present stage alternating-current switch, the air switches that use more, adopt manually of air switch controlled more, cannot accomplish that real-time Long-distance Control detects, in the time that circuit goes wrong, the air switch of must maintenance personal manually resetting, if the circuit in large region all adopts manual maintenance, be very time-consuming, therefore need a kind of also device of the switch closure of energy automatic control circuit of voltage that can automatically detect at any time in alternating circuit.
Utility model content
The purpose of this utility model is to solve existing technical matters, uses high power capacity, stronger power relay and the peripheral circuit of high withstand voltage, anti-transient voltage descent performance, realizes control and voltage detecting to high power load.Before solving, manual air switch cannot be realized the defect of remote switch control and on off state detection, has improved the reliability of system.
The technical solution adopted in the utility model: the high-power remote control AC switch module of 20A that a kind of state can be monitored, the relay of connecting in alternating current circuit, the input end of relay connects the input end of AC/DC converter A, and the output terminal of relay connects the input end of AC/DC converter B; The output terminal of described AC/DC converter A connects the positive pole of diode D3 and the collector of triode T2, the negative pole of diode D3 is to ground, the emitter of triode T2 is connected to the trigger end of relay, the grounded emitter of the triode T1 being of coupled connections with diode D3, collector is connected to MCU communication controler, and MCU communication controler is connected with the base stage of triode T2; The output terminal of described AC/DC converter B connects the two ends of diode D4, the grounded emitter of the triode T3 being of coupled connections with diode D4, and collector is connected to MCU communication controler.
In technique scheme, the output terminal of described AC/DC converter A connects positive pole and the hand switch T4 of diode D5, and the other end of hand switch T4 is connected to the trigger end of relay, and the negative pole of diode D5 is to ground.
The utility model is compared with existing product, volume is little, on the basis of existing manual air switch, increase automatic control switch, can realize the switch closure of local circuit by the Long-distance Control of host computer, the voltage condition that can also detect local circuit simultaneously, has promoted the robotization control of alternating voltage greatly.
Brief description of the drawings
Fig. 1 is circuit theory diagrams of the present utility model.
Embodiment
Now be described further by reference to the accompanying drawings.
As shown in Figure 1, the utility model comprises a powerful relay, relay is connected in the alternating current wires of 220V, at an AC/DC converter A of input end serial connection of relay, by AC/DC converter, alternating current is converted to direct current by A, the DC output end of AC/DC converter A connects the positive pole of diode D3, the negative pole of diode D3 is connected to ground, the positive pole of diode D3 connects the collector of a triode T2 again, the emitter of triode T2, the effect of triode T2 is the switch for controlling high power relay.The diode D3 triode T1 that is of coupled connections, the grounded emitter of triode T1, collector is connected to MCU communication controler, and MCU communication controler is connected with the base stage of triode T2.
Same at an AC/DC converter B of relay output end serial connection, AC/DC converter B output two-way power supply is connected to the two ends of diode D4, the diode D4 triode T3 that is of coupled connections, and the grounded emitter of triode T3, collector is connected to MCU communication controler.
When whole module is started working, MUC communication controler is by receiving the direct current signal after AC/DC converter A, AC/DC converter B conversion, can judge the voltage condition in alternating current circuit instantly, and carry out state demonstration by two diode D1, D2, when host computer is issued orders to MCU communication controler by RS485, MCU communication controler, by the base stage conducting of triode T2, provides signal conduction relay.
Being out of order for fear of automatic control switch, cause can not normal switch, connects one end of a hand control switch T4 and the positive pole of diode D5 at AC/DC converter A output terminal, and the other end of hand control switch T4 connects relay, and diode D5 negative pole is to ground.
MCU communication controler in the utility model can be monitored the voltage in alternating current circuit in real time, and feeds back to host computer, simultaneously by accepting the switch of the high power relay in the control signal control alternating current circuit of host computer.
Disclosed all features in this instructions, except mutually exclusive feature, all can combine by any way.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
