The present invention discloses a relay interlock separation control system. The relay interlock separation control system comprises: a first relay consisting of a first contact, a second contact, a third contact, a fourth contact, a fifth contact, a sixth contact and a first instruction input node; a second relay consisting of a seventh contact, an eighth contact, a ninth contact, a tenth contact, an eleventh contact, a twelfth contact and a second instruction input node; an instruction power supply connected with the third contact and the ninth contact; a first signal input end connected with the sixth contact; a second signal input end connected with the twelfth contact; a first subsystem connected with the fourth contact of the first relay; a second subsystem connected with the eleventh contact of the first relay; and a third subsystem connected with the fifth contact and the tenth contact. The present invention also discloses a control method of a relay interlock separation control system. According to the invention, the control system is simple in structure, the control method is simple in flow, and the relay interlock separation control system and the control method thereof are easily realized in a project.
Description
technical field [0001] The invention relates to the technical field of control circuits, in particular to a relay interlocking separation control system and a control method thereof. Background technique [0002] Generally, the execution of relay instructions is in an independent state, but the simultaneous execution of multiple instructions in a specific field will cause the system to work beyond the boundary or not work normally. Therefore, it is necessary to limit the command signals of the same relay to have only one command in the working state, and the rest of the command signals are in the locked state to ensure the normal operation of the system. For example, the patent document with publication number CN201210202530 discloses an interlock circuit and an interlock system including the interlock circuit. The interlocking circuit adopts an electromagnetic relay, and realizes the interlocking function by independently controlling the triode. This method realizes the c...
