（10ms）Subtract the action delay value of relay；When after Control delay value, control module transmits a signal to reception
Module control relay closes, when after action delay value, trigger module is completed to close, and forms power circuit, now entirely
Process just undergoes the civil power half period, and relay contact closure effectively can avoid relay from using on the zero crossing of civil power
When produce larger current, pulse relay contact, so can effective protective relay contact, extend relay service life；
Resistance capaciting absorpting circuit need not be increased, avoid producing leaky, securely and reliably, input cost is low.
As optimization technique measure, control chip is provided for obtaining the acquisition module that outside energization requires signal, described
Acquisition module is that button either triggers screen or triggers circuit, is easy to the break-make of control relay.
As optimization technique measure, the control chip is single-chip microcomputer either digital signal processor or field-programmable
Logical device.It is preferred that single-chip microcomputer（MCU）, disposal ability is powerful, is easily programmed, and purchase cost is low, reduces the utility model
R＆D costs.

Mouth voltage is maintained within 5.7V, avoids too high voltage from damaging single-chip microcomputer detection module.
Compared with prior art, the utility model has the advantages that：
After civil power zero crossing, that is, produce rising edge signal, civil power detection module（Circuit directly connects civil power）External interrupt
It is triggered, control module performs Control delay value in interruption, and Control delay value is equal to the civil power half period
（10ms）Subtract the action delay value of relay；When after Control delay value, control module transmits a signal to reception
Module control relay closes, when after action delay value, trigger module is completed to close, and forms power circuit, now entirely
Process just undergoes the civil power half period, and relay contact closure effectively can avoid relay from using on the zero crossing of civil power
When produce larger current, pulse relay contact, so can effective protective relay contact, extend relay service life；
Resistance capaciting absorpting circuit need not be increased, avoid producing leaky, securely and reliably, input cost is low.
