Description
Affiliated technical field
The invention belongs to electric switch, but particularly relate to a kind of automatic change-over with optimization power supply.
Background technology
Along with electronics, computer technology are widely used in the low-voltage electrical apparatus field, Intelligent Type Automatic Transfer Switch is to answer the market demand and the new type auto change over switch that is born.Its defencive function intellectuality, the volume miniaturization, structural module is the inexorable trend of development.The working power of electronic circuit board all is to be provided mutually by the A phase of power supply commonly used or the A of stand-by power supply in present known automatic change-over, when the power supply A phase voltage commonly used of supplying with the work of automatic change-over electronic circuit board or stand-by power supply A phase voltage instability, automatic change-over can not guarantee operate as normal.The reliable operation that this and automatic change-over propose is contrary.
Summary of the invention
But the present invention provides a kind of automatic change-over with optimization power supply for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: it includes two nodes of a direct current relay, electronic circuit board working power, two nodes of drive motors, and it also includes I/01, I/02 port and two optocouplers of another direct current relay, single-chip microcomputer; One end of two normally opened contacts on described two direct current relays all is connected with two nodes of described electronic circuit board working power and two nodes of drive motors respectively, and the other end of two normally opened contacts on the described direct current relay is connected with N mutually with the A of power supply commonly used, and the other end of two normally opened contacts on described another direct current relay is connected with N mutually with the A of stand-by power supply; The I/01 port of described single-chip microcomputer links to each other with the input of one of them optocoupler is anodal, and the input negative pole of this optocoupler links to each other with N, the I/02 port of described single-chip microcomputer links to each other with the input of another optocoupler is anodal, and the input negative pole of this another optocoupler links to each other mutually with N; The actuation coil of described direct current relay links to each other with the direct current relay both ends of power with optocoupler output series connection back with the two ends of the normally-closed contact of another direct current relay; The actuation coil of described another direct current relay links to each other with the direct current relay both ends of power with another optocoupler output series connection back with the two ends of the normally-closed contact of described direct current relay.
Advantage and good effect that the present invention has are: owing to adopted selectable two-way power supply power supply, all there is only power supply to provide in any case on the electron plate, having strengthened the coefficient of safety of entire circuit work and the safety factor of action, is the necessary condition of the reliable smooth working of automatic change-over.

Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, I/01, I/02 are respectively two ports of PIC18F6520 single-chip microcomputer, the I/01 port of single-chip microcomputer links to each other with the input of optocoupler RS1 is anodal, the input negative pole of optocoupler RS1 links to each other with N, the I/02 port of PIC18F6520 single-chip microcomputer links to each other with the input of optocoupler RS2 is anodal, and the input negative pole of optocoupler RS2 links to each other with N; The actuation coil of direct current relay J1 links to each other with 24 volts of both ends of power with optocoupler RS1 output series connection back with the two ends of the normally-closed contact of direct current relay J2; The actuation coil of direct current relay J2 links to each other with 24 volts of both ends of power with optocoupler RS2 series connection back with the two ends of the normally-closed contact of direct current relay J1.
See also Fig. 2, J1, J2 are the voltage-controlled direct current relay of 24V.The two ends of working power link to each other with an end of two normally opened contacts of direct current relay J1 simultaneously again and to link to each other with an end of two normally opened contacts of direct current relay J2.The two ends of same drive motors while that also links to each other with an end of two normally opened contacts of direct current relay J1 links to each other with an end of two normally opened contacts of direct current relay J2 again.The other end of two normally opened contacts of direct current relay J1 then links to each other with the N line mutually with the A of power supply commonly used.And the other end of two normally opened contacts of direct current relay J2 then links to each other with N mutually mutually with the A of stand-by power supply.
Which is more suitable for usefulness as working power and drive motors to the working procedure of single-chip microcomputer in order to judge earlier commonly used and standby two-way power supply, and single-chip microcomputer is controlled its whether conducting by an optocoupler, thus control be power supply A commonly used mutually or stand-by power supply A power mutually.
As shown in Figure 3, reliable adhesive of direct current relay J1, J2 and disconnection required voltage are lower than the voltage of reliable drive motors, so as long as we can guarantee that operating voltage is higher than the voltage of reliable drive motors (180V) in program, the condition of work of direct current relay J1, J2 has also satisfied.At first the PIC18F6520 single-chip microcomputer compares the effective value and the 180V of power supply A phase commonly used, greater than using a power supply A direct power supply mutually often; Less than the time again the effective value and the 180V of stand-by power supply A phase compared, greater than the time stand-by power supply A direct power supply mutually, less than the time two-way power supply reliable drive motors all.
