Fig. 1 shows the circuit diagram of the said standby zero-power of the utility model circuit.
Embodiment
As shown in Figure 1; The standby zero-power circuit of the utility model comprises single-chip microcomputer (not shown), power supply unit 3, relay R Y1, switching tube Q1 and microswitch SW1; The live wire input end INPUT-L of this power supply unit 3 is electrically connected with the fire-wire interfaces ACL of standby zero-power circuit; The coil of relay R Y1 and switching tube are series between the positive output end OUTPUT+ and negative output terminal OUTPUT-(being generally earth terminal) of power supply unit 3, and this control end of switching tube is electrically connected with the enable port control of single-chip microcomputer; The zero line interface ACN of standby zero-power circuit is electrically connected with the first common COM1 of first normally closed switch of relay R Y1; The first normally closed contact NC1 of first normally closed switch of relay R Y1 is electrically connected with the normally opened contact of microswitch SW1; Be preferably through buffer resistance R2 (particularly wire-wound resistor) and be electrically connected with the normally opened contact of microswitch SW1; The common COM of microswitch SW1 is electrically connected with the second common COM2 of second normally closed switch of relay R Y1; Normally closed contact NC one branch road of microswitch SW1 is electrically connected with the negative output terminal OUTPUT-of power supply unit through the 4th resistance R 4, and another branch road is electrically connected with the voltage acquisition port sensor of single-chip microcomputer; First normally opened contact NO1 of first normally closed switch of relay R Y1 and the second normally closed contact NC2 of second normally closed switch all are electrically connected with the zero line input end INPUT-N of power supply unit; The second normally opened contact NO2 of second normally closed switch of relay R Y1 is electrically connected with the positive output end of power supply unit.In addition, single-chip microcomputer is by power supply unit 3 power supplies, and promptly the power input mouth of single-chip microcomputer is electrically connected with the positive output end OUTPUT+ of power supply unit 3.
This power supply unit 3 is power supplys of complete machine, and other that promptly is also responsible for electrical equipment supplied power with electric device, can be transformer voltage dropping power supply, Switching Power Supply or resistance-capacitance depressurization power supply, and, isolate or non-isolation all can.
The principle of work of the standby zero-power circuit of the utility model is: the fire-wire interfaces ACL of the standby zero-power circuit line of starting to exchange fire; Directly get into the live wire input end INPUT-L of power supply unit 3; Zero line interface ACN connects the civil power zero line; Be connected to the first common COM1 of relay R Y1; First and second normally closed switchs of relay R Y1 its coil not under the electric state (being original state), the first common COM1 and the first normally closed contact NC1 connect, zero line is received the normally opened contact NO of microswitch SW1 through second resistance R 2.At this moment, the zero line input end INPUT-N of power supply unit 3 with on zero line is connected, therefore, do not work by power supply unit.
When the user pressed microswitch SW1, its normally opened contact NO and common COM connected, the zero line input end INPUT-N that zero line is connected to power supply unit 3 through the second common COM2 and the second normally closed contact NC2 of second normally closed switch of relay; At this moment; Power supply unit 3 work, output voltage (being+5 in the present embodiment) provides power supply to single-chip microcomputer, and single-chip microcomputer is accomplished the back that resets and is made switching tube Q1 conducting through its enable port control output low level or high level; The coil of relay R Y1 is got; At this moment, the first common COM1 of first normally closed switch of relay and the first normally closed contact NC1 break off, and connect with the first normally opened contact NO1; The second common COM2 of second normally closed switch and the second normally closed contact NC2 break off, and connect with the second normally opened contact NO2; The zero line input end INPUT-N that zero line is added to power supply unit 3 through the first common COM1 and the first normally opened contact NO1 of relay R Y1, even at this moment unclamp microswitch SW1, power supply unit 3 also will work on.
The process that deenergization connects: the common COM that accomplishes the microswitch SW1 that resets after the boot action is electrically connected with normal-closed end NC, and the second common COM2 of second normally closed switch through relay and the second normally opened contact NO2 be connected to positive output end OUTPUT+ (be in the present embodiment+5V).What like this, the voltage acquisition port sensor of single-chip microcomputer read in is high level.When the user presses microswitch SW1 once more; Its normally closed contact NC and common COM end break off; The voltage acquisition port sensor of single-chip microcomputer is dragged down by the 4th resistance R 4; The voltage acquisition port sensor of single-chip microcomputer detects after this variation (after promptly detecting negative edge), and control output high level or low level are ended switching tube Q1 in its enable port; And be maintained to microswitch SW1 and reset, and then make the coil losing electricity of relay R Y1, thus of the connection of civil power zero line broken off fully to power supply unit.When single-chip microcomputer is received the remote-control closedown signal or accomplished corresponding task when carrying out the shutdown action, same control output low level or the high level of only needing in the enable port can be realized.
In the present embodiment; As shown in Figure 1; This switching tube Q1 is the positive-negative-positive triode; The coil of this relay R Y1 is electrically connected between the negative output terminal OUTPUT-of collector and power supply unit 3 of triode, and the emitter of this triode is electrically connected with the positive output end OUTPUT+ of power supply unit 3, and the ground level of this triode is electrically connected with the enable port control of single-chip microcomputer through current-limiting resistance R3 as control end.For this kind structure, enable port control output low level can make the triode conducting, and the output high level can make triode end.In addition, reversal connection has diode D1 between the negative output terminal OUTPUT-of the collector of this triode and power supply unit 3, for the coil of relay R Y1 provides the back discharge loop.
Can also be electrically connected with the parallel circuit of filter capacitor EC1 and discharge resistance R1 between the positive output end OUTPUT+ of this power supply unit 3 and the negative output terminal OUTPUT-.
Certainly; Those skilled in the art should be understood that; Can change the interface that is connected all the time with power supply unit in fire-wire interfaces and the zero line interface, such scheme be with fire-wire interfaces as the interface that connects all the time, also can the first common COM1 of relay R Y1 be connected to fire-wire interfaces ACL; And the zero line input end INPUT-N of power supply unit is electrically connected with zero line interface CAN; Simultaneously, the live wire input end INPUT-L of power supply unit is electrically connected with first normally opened contact NO1 of first normally closed switch of relay and the second normally closed contact NC2 of second normally closed switch, and the second normally opened contact NO2 of second normally closed switch is electrically connected with the negative output terminal OUTPUT-of power supply unit; And, the 4th resistance is electrically connected between the positive output end OUTPUT+ of normally closed contact NC and power supply unit of microswitch SW1.For this kind equivalent structure, the voltage acquisition port sensor of single-chip microcomputer deenergization when collecting rising edge connects.
Being merely the utility model preferred embodiment in sum, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to the technological category of the utility model.
