Carry out the charge of self-capacitance C5 storage.When the power supply of 220V power system restoration, diode D1 is lighted again, and the 5 feet output of photo-coupler M is low
Level, the blocking of oscillator, capacitor C5 is full of charge again to be used for the alarm that has a power failure next time, and circuit has abandoned pollution-carrying dry electricity
Pond power supply structure is powered after power failure to GPRS module by the way of capacitive energy storage, and the transmission terminal setting of GPRS is using
On the mobile phone or computer of person, once there is power blackout situation, power blackout situation can be understood whenever and wherever possible, takes counter-measure in time.
Therefore this circuit has the advantages that structure is simple, use cost is low, energy conservation and environmental protection and remote alarms.
