Description

Intelligence is from the motor operated switch of keeping connection status

Technical field:

The utility model relates to a kind of electrical equipment.

Background technology:

Present automatic switch can only mechanically be carried out the instruction of connection or deenergization, the residing state of electrical equipment when it can not understand and feed back the execution command front and back, so, can not cooperate to mix with existing hand switch and use.In addition, existing automatic switch power consumption with common relay is bigger, in case and control system faults such as outage take place, the state of relay can't be kept, the on off state of electrical equipment is change automatically.

Summary of the invention:

The purpose of this utility model is to provide a kind of intelligence from the motor operated switch of keeping connection status, it can be according to the instruction of control system, cooperate with the common manual ganged switch, mix and be used to complete operation, keep controlled electrical equipment state, controlled electrical equipment state is constant when controller failure or outage.

The utility model is achieved in that intelligence is from keeping the motor operated switch of connection status by main body, shell and latch-in relay are formed, main body is made up of controller, address scrambler, state detector, controller is connected with address scrambler, state detector respectively, and be connected with the order wire and the power lead of control system, the information of external and address scrambler, state detector can be accepted, be differentiated, send to controller; Address scrambler is by symbolic representation, and symbol can freely be set; After state detector detects the state of the electrical equipment present located Push And Release that this electronics automatic control switch controlled, the information of testing result is sent to controller, it is different with the instruction of receiving that controller is differentiated testing result, the position change that just instructs the pin of latch-in relay to connect, it is identical with the instruction of receiving that controller is differentiated testing result, just instructs the position of pin connection of latch-in relay not change.The latch-in relay pin is a single-pole double-throw (SPDT), two of an inlet wire pin a goes out wire pin b, c, two go out to have all the time among wire pin b, the c one to be connected with inlet wire pin a, no matter are connected that and go out on the wire pin, keep existing connection status without electric power after the connection.State detector is the state of induction apparatus on the power lead that connected of the inlet wire pin a from latch-in relay.The symbol of address scrambler is by arabic numeral or letter representation.The part of stirring of address scrambler is exposed on shell.There is tie point that lead-in wire is connected with pin a, the b of latch-in relay, c respectively on the shell.The interface of communication interface and main body power supply exposes on shell.

The utility model is used for control system, can be used with traditional hand switch, reaches manually to mix the effect of using automatically.Power consumption is little during use, and the electrical equipment state can keep.

Description of drawings:

Accompanying drawing 1 is the utility model circuit structure connection diagram.

Wherein: (1) is main body, and (2) are controllers, and (3) are communication interfaces, and (4) are the main body power interfaces, and (5) are address scramblers, and (6) are control pins.JC is a state detector, and ZJ is a latch-in relay.SK is a hand switch, and DQ is an electrical equipment.

Embodiment:

Below in conjunction with accompanying drawing foundation embodiment of the present utility model is described in detail.

With reference to accompanying drawing 1, main body power interface (4) inserts low-tension supply, keeps each several part work, and communication interface (3) is communicated with the inside and outside information interchange of controller (2).State detector JC is an induction installation around the magnet ring of insulated wire, one in the 220V power lead is passed from magnet ring, when electric current passes through, state detector JC can detect immediately, and information sent to controller (2), and address scrambler (5) can be made up of one or more symbols as required, and symbol can be arabic numeral, also can be letter, purpose be the address that gives an identification of control system.Latch-in relay ZJ respectively has two control pins (6) and three pin a, b, c, one is advanced pin a in three pins, two go out pin bc, one of them goes out pin and is connected with b, c all the time to advance pin a, the control of the controlled device of concrete link position (2), and controller (2) is controlled latch-in relay ZJ by control pin (6), and whole intelligence is finished Based Intelligent Control from the motor operated switch of keeping connection status by arranging inlet wire to be connected with different outlet.Latch-in relay among the embodiment is a magnetic latching relay.

For example: electrical equipment DQ1 is in the state of unlatching, and electrical equipment DQ2 is in closing state.Controller (2) is received instruction now, electrical equipment DQ1 to close, and controller (2) instruction latch-in relay ZJ1 changes the position of inlet wire connection, becoming a is connected with b, for a is connected with c, electrical equipment DQ1 closes smoothly, and controller (2) outwards sends the information of " instruction is finished ".This switching process of above situation is that common electronic switch is also adequate.

But,, but receive the instruction of unlatching if controller (2) is not to receive the instruction of cutting out, (this situation probably takes place, because the people of control is not necessarily at the scene of electrical equipment), if, can not finish instruction only with simply changing the position that inlet wire connects.This situation just is not that common electronic switch is adequate.

Intelligent switch processing procedure of the present utility model is such: when controller (2) when receiving any instruction, detect the residing state of electrical equipment CQ by state detector JC earlier, when the state of detected state and instruction is identical, controller (2) is not just done any instruction to latch-in relay ZJ, and outwards sends the information of " instruction is finished ".If the state of detected state and instruction is inequality, controller (2) is just done the instruction of the position of change inlet wire connection to latch-in relay ZJ, when having confirmed instruction and the state of electrical equipment is consistent, just outwards send the information of " instruction is finished ".So when running into the situation that to open the electrical equipment of having opened, do not change the position of connection with regard to commands relays.

Again for example: DQ2 is because the hand switch changing position, it now has been the state of unlatching, at this moment controller (2) is received the instruction of unlatching, can not correctly finish instruction if instruct latch-in relay ZJ to change the position that connects simply, so common electronic switch can not be used with manual ganged switch SK.And intelligent switch of the present utility model is because can detect the present state of electrical equipment DQ, so can cooperate use with manual ganged switch SK.

Without latch-in relay ZJ, with the relay of common single-pole double-throw (SPDT), also can be used, but when having a lot of relays to use together, the electricity consumption of keeping relay may be very big with manual ganged switch SK, the burden of power supply is very big.In case and main body breaks down or cut off the power supply, relay can not keep original connection status, and relay has changed connection status, and the on off state of electrical equipment DQ also will cause consequence hardly imaginable along with automatic change.
