Junction point and resistance R12 between connects the in-phase input end of amplifier element, outfan series resistance R14 of amplifier element, two
Export to single-chip microcomputer after pole pipe D1, Schmidt trigger.Amplifier element adopts hysteresis loop comparator to prevent from exporting square wave in input
Shake is produced, it is to avoid affect the accuracy of detection and stablizing of system near signal zero crossing.The output square-wave signal of comparator
Input single-chip microcomputer through Schmidt trigger 74HC14, to increase the reliability of system.The RB0 of RB port of 16F877 single-chip microcomputer and
RB4-RB7 is complex function pin, can detect the level change on pin.If pin RB4-RB7 is set to input drawn
Foot, when control bit RBIE puts 1, RB4-RB7 level change (rising edge and trailing edge are all effective) occurs will trigger interruption, this
Plant characteristic to be especially suitable for gathering crossover point signal.Can be according to the sequential of switching manipulation, i.e. timer, at a time only will
Single one pin in RB4-RB7 is set to input pin, and other pins is set to export, so when certain pin occurs level
Change RBIF puts when 1 generation is interrupted it is possible to determine voltage, the zero crossing moment of electric current.
As shown in fig. 6, when over-voltage and over-current phenomenon occurs in system, can be controlled by switch driving circuit, break
Circuit breaker, the reverse input end input of comparator is reference signal UREF1, in-phase input end can input three-phase voltage to be believed
Number UA, or three-phase current signal（IA、IB、IC）, after both being compared by comparator it can be determined that detection three
Whether phase current signal or voltage signal exceed the reference value of setting, then will compare the signal after output with benchmark in the same manner
Signal UREF2It is compared, thus carrying out judging whether having exceeded second reference value setting, each overload signal can be by
It is defined as OVER1-4, and by logic gates, OR-circuit carries out logical judgment, as long as there being an overload signal triggering,
Then export high level signal to single-chip microcomputer, thus being reported to the police.
Power factor (PF) module operation principle is：First with transformer, voltage, current analog signal are changed and sent into
The amplifier of programmable-gain, two Δ ∑ ADC are had, two highpass filters, with system school inside CS5460A, CS5460A
