Abstract
The utility model relates to a whole closedown control circuit for remote control electric appliance, which is made up of a signal detection element, a photoelectric separation element and a drive control element. The input end is closely connected with the power switch signal of the remote control electricity appliance micro processor or the main electricity power direct current voltage input end, and the another end links the remote control electricity appliance assistance power, to control the relay often open contact point parallel connect with the remote control electricity appliance power switch. When the remote control electricity appliance boot strap, the circuit detects the boot strap signal, the relay suck and shut down, the original electricity appliance is provided with a remote control boot strap and temporary functions. This time if remote control to shut down, then cut the relay, cut down the main power, thus realize the whole closedown function.
Description
The utility model relates to a kind of control circuit that is used for complete closedown in the remote control electrical appliance machine.Specifically, be that a kind of energy passes through the detection to off signal in the remote control electrical appliance machine, realize electrical equipment is carried out the circuit of complete closedown control.
Nearly all commercially available remote control electrical appliance all can not be realized remote control complete closedown function at present, behind remote-control closedown, alternating current is still connected, and not only will consume certain energy, and long-time energising, fragile electrical equipment, cause fire, cause heavy losses, therefore, must cut off AC power, to guarantee electrical equipment and property safety.But the mode of this cut-out AC power is operated especially inconvenience for the old,weak,sick and disabled person or in the winter of cold, though there is the minority product also to have the complete closedown function, can not remote-controlled start-up behind the remote-control closedown.
The utility model overcomes the limitation of above-mentioned prior art, its objective is that providing a kind of both can carry out remote control switch, the control circuit that has remote control complete closedown function again simultaneously.
The purpose of this utility model is achieved in that generally speaking the working power of remote control electrical appliance is formed by two ones, the accessory power supply that promptly special microprocessor is used and the main power source of complete machine work.The input test side of the utility model circuit links to each other with the switching on and shutting down signal output part of remote control electrical appliance microprocessor or the dc voltage output end of main power source, and the accessory power supply of the other end and remote control electrical appliance (for microprocessor with) be connected, the control relay normally opened contact is in parallel with appliance mains switch.During the electrical equipment start, this electric circuit inspection arrives starting-up signal, the relay adhesive, and former electrical equipment can carry out remote-controlled start-up and remote control suspends.If when needing the remote control complete closedown, only need mains switch is placed off-mode, control relay is adhesive still, the electrical equipment operate as normal, at this moment only need to press the remote-control closedown button, the input of circuit detects off signal or the main power source dc voltage output end power-off signal that machine inner microprocessor sends, and control relay disconnects, turn off general supply, thereby realize the complete closedown function.
The utility model partly is made up of switching on and shutting down input, photoelectricity isolation, drive controlling etc.
Electrical schematic diagram of the present utility model is provided by following examples and accompanying drawing.
Describe circuit theory and the working condition of the utility model embodiment in detail below in conjunction with Fig. 1:
In the accompanying drawing, resistance R 1, optocoupler PC form input signal detection and optically coupled isolation circuit; Resistance R 2, R3, optocoupler PC, triode Q, diode D, relay J are formed driving and complete closedown control circuit; K is the mains switch of former electrical equipment; The output of AB circuit closer microprocessor switching on and shutting down signal or the dc voltage output end of main power source, the dc voltage output end of CD circuit closer accessory power supply (the access voltage of this circuit design is 5V).
When appliance switch K connects, for providing the accessory power supply of power supply, microprocessor starts working in the machine, microprocessor is also in running order simultaneously, main power source then is in halted state, complete closedown control circuit port CD obtains operating voltage in the remote control electrical appliance machine, input test side AB no-voltage, and optocoupler PC is in cut-off state, the base stage of the triode Q of Drive and Control Circuit is placed in high level, and relay J disconnects.When remote-controlled start-up, microprocessor is exported a starting-up signal, main power source is started working, electrical equipment is in normal operating conditions, after the AB end detected starting-up signal, the optocoupler PC of optically coupled isolation circuit was in conducting state, and the base stage of the triode Q of Drive and Control Circuit is changed to low level, relay J gets electric and adhesive, and promptly J-1, J-2 connect.When remote-control closedown, microprocessor is exported an off signal, main power source quits work, after the AB end detects off signal, optocoupler PC is in cut-off state, and the base stage of triode Q is placed in high level, relay J dead electricity and disconnecting, in the case, no matter whether the J adhesive does not all influence the remote control time-out and the remote-controlled start-up function of former electrical equipment.
When electrical equipment was in normal operating conditions, if will make electrical equipment be in the complete closedown state, as long as disconnect appliance switch K, because of relay J is in attracting state, former electrical equipment is operate as normal still.When needing complete closedown, press the shutdown button on the remote controller, complete closedown control circuit input test side AB no-voltage in the machine, optocoupler PC and triode Q end, and relay J disconnects, thereby cuts off the general supply of electrical equipment, reaches the complete closedown purpose.
The element of the utility model example figure is selected: optocoupler PC:4N25; Triode Q:2SC8550; Relay J: JZC-22FA diode D:1N4001; Resistance R 1:1.2K Ω; Resistance R 3:5.1K Ω; Resistance R 2:30K Ω; Wherein the value of resistance R 1 is the value of AB when holding detected voltage to be 4.5～5.5V, if the size of detected voltage can be adjusted R1 not in this scope, guarantees the optocoupler operate as normal.
The utility model can be realized remote control complete closedown function under the situation that former remote control electrical appliance circuit does not make any changes, also kept present general remote control time-out and remote-controlled start-up function simultaneously, and simple in structure, dependable performance makes things convenient for the user greatly.
