S54: judge that hand is jumped and whether press, press if hand is jumped, turn S55, do not press if hand is jumped, turn S56;

S55: drive hand to jump relay 0.5S;

S56: judge anti-jump whether pressing, press if anti-jump, turn S57, do not press if anti-jump, turn S6;

S57: drive hand to jump hand and close relay 0.5S, turn S6.

In such scheme, described S6 comprises the steps:

S61: judge that hold mode exports;

S62: judge whether closing loop has electric current, if there is electric current to turn S63, if do not have electric current to turn S3;

S63: upset simulation circuit-breaker status after time delay dial-up setting-up time, turns S3.

Advantage of the present invention and beneficial effect are: the invention provides the mimic-disconnecting switch that a kind of volume is little, easy to use.This mimic-disconnecting switch module can realize external hand combined floodgate, external hand trips, isolating switch is anti-jump, whether trip(ping) circuit has maintenance function, and whether closing circuit has the feature keeping function.This module is made up of electronic circuit, the action logic of mimic-disconnecting switch mechanism that can be completely complete, and whether the maintenance loop detecting microcomputer device inside is targetedly normal, reduce the volume of coordinative experiments equipment greatly, greatly improve production testing efficiency, have compressed the cost of supporting checkout equipment greatly.

Embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.

As shown in Figure 1, the present invention is a kind of volume mimic-disconnecting switch little, easy to use, comprise pick-up unit 1, processor 2, display 3 and input key 4, DC power supply circuit 5, hand jumper ring circuit 6, hand conjunction coil circuit 7 and anti-jump coil circuit 8 is included in processor 2, pick-up unit 1 is connected with processor 2, and processor 2 is connected with display 3, and processor 2 is connected with input key 4, processor 2 is single-chip microcomputer, and display 3 is light-emitting diode display.
