Description
Technical field
The present invention relates to the power supply changeover device field, be specifically related to a kind of intelligent lightning-proof electricity-saving power supply changeover device.
Background technology
But power supply changeover device mainly contains the conducting and the disconnection of the mutual control relay of monostable flipflop of monostable flipflop and the not reproducible triggering of a repeated trigger, thereby accomplishes the conducting and the disconnection of power supply changeover device.The shortcoming that exists is that the phenomenon of not conducting appears in the power supply changeover device that powers on sometimes.
Power supply changeover device itself also is an electrical equipment, and when the electrical equipment on being connected on power supply changeover device was not worked, it also can produce the loss of electric current, the waste electric energy.
Be connected to a large amount of electrical equipment on the power supply changeover device; These electrical equipment adopt integrated device mostly; When thunder and lightning produces, can around it, produce an electromagnetic field, this electromagnetic field inducing will produce a powerful electromotive force to appliance circuit; This electromotive force is scurried into electrical appliance through power circuit, is enough to damage circuit.
Summary of the invention
The technical problem that the present invention will solve provides a kind of rational in infrastructure, power supply changeover device that the triggering and conducting control ability is strong, easy to use and quick, energy-conservation.
Content of the present invention is to comprise: trigger control circuit, relay drive circuit that links to each other with trigger control circuit drive signal output and the sensor trigger circuit that links to each other with the trigger control circuit input; But said trigger control circuit comprises monostable control circuit of repeated trigger and not reproducible triggering monostable control circuit; Said not reproducible triggering monostable control circuit is provided with delay circuit.
Preferably; Said not reproducible triggering monostable control circuit is included as the NE555 integrated circuit; Said delay circuit comprises resistance and electric capacity; Said resistance is connected between NE555 ic power input and the signal triggering end, and said electric capacity is connected between NE555 integrated circuit signal trigger end and the cold end.
Preferably; Said relay drive circuit comprises transistor; Said transistor is provided with base stage, collector and emitter; Said base stage connects the drive signal output of trigger control circuit, and collector connection relay signal controlling input also is connected the power input of relay through voltage stabilizing didoe, and emitter connects electronegative potential.
Preferably, said transistor is a triode
Preferably, said triode is a NPN type triode.
Preferably; Said triggering sensor circuit comprises inductive switching circuits for triggering, infrared induction circuits for triggering or acoustic control sensor trigger circuit, and the signal output part of said inductive switching circuits for triggering, infrared induction circuits for triggering or acoustic control sensor trigger circuit links to each other with trigger control circuit induced signal input.
Preferably, the present invention includes the power circuit into trigger control circuit, relay power supply, said power circuit is two conversion electric power circuit.
Preferably, the present invention also comprises the protective circuit parallelly connected with power circuit, and said protective circuit is the thunderbolt current foldback circuit.
The invention has the beneficial effects as follows; The present invention is mainly from the current minimizing wasting of resources be convenient for people to use and life; Adopt digital device to control the mode of analogue device, have only digital circuit work and high-tension analog circuit is not worked in normality, thereby reduced the waste of power; Use sound and infrared these common triggering sources as triggering on the other hand, people should be used not only simply but also quick.
The present invention can be divided into five parts on structure; As shown in Figure 1; First mainly is made up of and finally generates the DC power supply of 5V and 24V power choke coil, polypropylene capactive, resistance and three-terminal voltage-stabilizing circuit; 24V as relay conducting whether control voltage, 5V is as the operating voltage of chip.Shown in Fig. 2-3; Second portion is made up of 74HC123 and two monostables of NE555; But the former is the monostable of repeated trigger; Its trigger end has the decision of main frame power output, after current transformer will induce the effect of a small electric current through two comparators and triode when main frame has power output, gives a low level triggering when will also not finish fully in the temporary stable state of 74HC123 again; Thereby realize that as long as the phenomenon of host work relay conducting always NE555 then becomes its trigger end of the most basic monostable circuit and is connected on the output with door CD4082.Shown in Fig. 4-6, third part is the circuits for triggering that miaow head, switch and infrared remote receiver are formed, their output be connected on four inputs with door on, be connected on monostable input of NE555 with the input of door.As shown in Figure 7, the 4th part is the switching circuit of relay, and is as shown in Figure 8, and the 5th part is a lightning prevention circuit.
The difference of the present invention and normally used power supply changeover device is to be not only to be shown in like three in figure to have increased acoustic control and infrared triggering on the function; The conducting of the relay of monostable control is arranged shown in figure two simultaneously; Thereby realized reducing the power dissipation when main frame does not have electricity, so not only reduced the loss of the energy but also made things convenient for everybody life, the input-output equipment that the while is connected with main frame when host work is also worked simultaneously; If main frame is work not; Then but monostable input of the repeated trigger among the figure two detects less than low level, and (the resistance capacitance decision that has monostable to connect) monostable arrives stable state after a while, and relay is broken off; Thereby make the input-output equipment that connects host computer accomplish outage, reduce the power consumption of input-output equipment.
