Be described in detail below in conjunction with the control procedure of accompanying drawing a kind of Zero-power-consumption standby and safe operation power control:
As shown in Figure 5, described ac power switch 2 in a kind of Zero-power-consumption standby and the safe operation power control is mechanical switch combinations of a kind of relay structure, comprise driver 201, auxiliary reclay (line bag 202, contact 203), power relay (line bag 204, contact 205);
This is a typical relay control structure of being made up of auxiliary reclay, power relay, one end of the line bag 202 of auxiliary reclay connects described controller 1 by driver 201, and the other end of auxiliary reclay line bag 202 connects the working power VDD of control device.The normally opened contact 203 of auxiliary reclay is connected across on the AC power after connecting with the line bag 204 of power relay, AC power observation circuit 3, and the normally opened contact 205 of power relay is connected in the AC power line of controlled device; When described controller 1 by driver 201 make auxiliary reclay line bag 202 electric, normally opened contact 203 closures of auxiliary reclay, the line bag 204 of power relay electric, the normally opened contact 205 closed AC power of connecting controlled devices of power relay.
Because the adhesive of auxiliary reclay has a long way to go with keeping energy consumption, described controller 1 can be by two control end R_CON1 of described driver 201, R_CON2 accurately controls the adhesive and the maintenance process of auxiliary reclay, thereby reduces the energy consumption that produces on described standby power 5 in the auxiliary reclay attracting process to greatest extent.
