Background technology
At present, existing double power supply automatic transfer switch controller, general work voltage is 160V～260V, if run into the wrong line, causes operating voltage too high, causes controller to burn easily, and influences operate as normal.Because the double power supply automatic transfer switch controller generally adopts the potentiometer regulation voltage, and not only there are defectives such as precision and poor reliability in sort controller, also make troubles simultaneously simultaneously for operating personnel.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the utility model provides a kind of double power supply automatic transfer switch controller that can control in wide-voltage range.
The technical scheme that the utility model is taked is: a kind of double power supply automatic transfer switch controller, comprise power circuit, drive circuit, and also comprise with power circuit, drive circuit being connected, and the single-chip microcomputer of supervisory keyboard and digital display tube; It is characterized in that: described power circuit is to be connected piezo-resistance RA, RB, RC and RD between the phase line of power supply commonly used and stand-by power supply and N line; Between the N line of power supply commonly used and stand-by power supply, connect piezo-resistance RE; The power input of power supply commonly used and stand-by power supply is connected transformer T1, T2 input respectively, transformer T1, T2 output connect the input of silicon bridge D1, D2, transition diode V1 and capacitor C 1 are connected in parallel on the output of silicon bridge D1, D2, resistance R 1, R2 are connected on respectively on the output of silicon bridge D1, D2, and capacitor C 2 is connected in parallel between resistance R 1 and the R2; Described drive circuit is delivery outlet P1, P2, P1 ', P2 ' difference series resistance R3, R4, R5, the R6 by single-chip microcomputer, resistance R 3 links to each other with the base stage of triode N1, N2 respectively with R4, the collector electrode of triode N1, N2 links to each other, the emitter of triode N1 is succeeded electrical equipment J1, the grounded emitter of triode N2, diode D3 is connected in parallel on the two ends of relay J 1 coil; Resistance R 5 links to each other with the base stage of triode N3, N4 respectively with R6, and the emitter of triode N3, N4 links to each other, the collector connecting relay J2 of triode N3, and the grounded collector of triode N4, diode D4 is connected in parallel on the two ends of relay J 2 coils; On the delivery outlet P3 of described single-chip microcomputer, connect buzzer FM.
Operating voltage range is narrow thereby the double power supply automatic transfer switch controller of taking technique scheme has been avoided, and takes place because of the wrong line causes the accident of burning controller easily.The utility model adopts keyboard to adjust input voltage value, has replaced traditional potentiometer and has regulated, thereby avoided causing problems such as low precision and poor reliability because of potentiometer wears out.Therefore the utility model not only satisfies required precision, has improved reliability and stability simultaneously, also provides convenience for operating personnel.
In order to improve controller reliability, reach required precision, the utility model takes single-chip microcomputer to control.In order to satisfy the monitoring voltage precision, at first single-chip microcomputer is gathered each road magnitude of voltage, and the magnitude of voltage that collects is shown by digital display tube, then the magnitude of voltage that shows by the keyboard adjustment; Single-chip microcomputer is revised the keyboard input voltage signal of gathering, and more revised magnitude of voltage is sent into digital display tube and is shown and store, and reaches the required precision of controller thus.When single-chip microcomputer collect produce the signal of too high voltages because of the wrong line after, deliver to buzzer by single-chip microcomputer and report to the police.
For prevent controller power on, under dead electricity or the strong electromagnetic situation, the misoperation of output relay, the utility model by two of single-chip microcomputers independently the I/O mouth control two NPN and PNP triode respectively, drive the conducting of relay or end.
In design of transformer, adopting input service voltage is 160V～400V wide region transformer.If run into the wrong line, controller is operate as normal still.Avoid burning the generation of controller accident, thereby improved the reliability and the stability of controller.In order to reduce cost, improve antijamming capability, connect by moment at two outputs of silicon bridge and become the anti-interference resistance-capacitance network that diode, resistance, electric capacity are formed.
