Abstract
The invention is an AC relay correcting method and device, correcting ON/OFF response time difference of the relay connected with microprocessor unit by correction program stored in the microprocessor unit. As the correction program requires the relay to make ON/FF action, the microprocessor unit outputs relay ON/OFF action signal and simultaneously obtains 50/60Hz zero-crossing ON/OFF response time difference by first detection unit connected between the microprocessor unit and relay, then calculates delay time value of the next 50/60Hz zero- crossing by the correction program, and stores relay ON/OFF action delay correction time value so as to determine the needed delay time for the next relay startup.

Thus, above-mentioned parts constitute the means for correcting that can proofread and correct relay 5, and this device at the waveform of timing as shown in Figure 2.The A waveform is represented relay 5 employed AC power (50/60HZ), and on behalf of first contact (COM) 51 of relay 5, A1 (zero cross point) switch the reaction time point that is connected to second contact (NO) 52 or disconnects from second contact (NO) 52.
The B waveform is second detecting unit 3 oscillogram of 50/60HZ basic time of feedbacking that microprocessing units 1 interpretation detects.
The C waveform is the relay 5 open/close oscillograms that microprocessing unit 1 is exported.
The D waveform represents that first detecting unit detects and 51 switchings of first contact (COM) of the relay 5 of back coupling are connected to second contact (NO) 52 or poor from the reaction time that second contact (NO) 52 disconnects.
When relay 5 produces the adhesive action, microprocessing unit 1 utilizes second detecting unit 3 (as the B waveform of Fig. 2) to obtain the time reference of zero cross point, calculate back output enabling signal (as the C waveform of Fig. 2), this enabling signal is sent to the 3rd contact 53 of relay 5 through switch 4, make electromagnet produce the suction-combining force, 5 on relay is switched by first contact (COM) 51 and is connected to second contact (NO) 52.This moment, first contact (COM) 51 with detected relay 5 switched poor the back coupling to microprocessing unit 1 (as the D waveform of Fig. 2) of the reaction time that is connected to second contact (NO) 52.After the calibrated software program of enabling signal that the poor and previous microprocessing unit 1 of reaction time that microprocessing unit 1 is feedback according to first detecting unit 2 is exported is made comparisons, obtain value time delay of (T-Δ X), therefore when starting relay 5 next time, how long just know needs to postpone.
