Abstract
The utility model relates to an infrared remote control AC starting up and off device, which belongs to the technical field of electronics, and comprises a regulated power supply circuit, a remote control signal acquisition circuit, a maintenance signal acquisition circuit, a signal shaping circuit, an executive circuit and the like. The regulated power supply circuit provides power for the wholemachine. A pulse string with encoding information sent by a remote control is inverted and filtered by the remote control signal acquisition circuit and then is sent to the shaping circuit. The maintenance signal acquisition circuit consists of a mutual inductor and a rectification filter circuit, when an electric appliance works, and the induced electromotive force generated by the mutual inductor is filtered and then sent to the shaping circuit by the maintenance signal acquisition circuit. The shaping circuit shapes the two signals and then sent the signals to the executive circuit, and controls the actuation and release of a relay so as to achieve the purpose of remote controlling the AC starting up and off. The utility model is applicable to remote control electric appliances (i.e. color TVs, air conditioners and the like), and has the advantages of safety, energy saving and prolonged service lives of the electric appliances.
Description
Technical field
The utility model relates to a kind of infra-red remote control and exchanges start and ac dump device, belongs to electronic technology field.
Background technology
A lot of remote control electrical appliances (as colour TV, air-conditioning etc.) enter family, bring convenience to the user.But most remote control electrical appliances do not have remote control ac dump function, and many users have selected remote-control closedown for convenience when shutdown, make remote control electrical appliance be in holding state for a long time.And remote control electrical appliance is still being worked at holding state lower part circuit, still consuming suitable electric energy, has both wasted electric energy, has potential safety hazard again, also influences the serviceable life of electrical equipment.Also there is the minority remote control electrical appliance that the ac dump function is arranged at present, but can not starts shooting with telepilot behind the ac dump, make troubles to the user.
Summary of the invention
The purpose of this utility model is to provide a kind of infra-red remote control to exchange start and ac dump device for overcoming above-mentioned weak point of the prior art.
The designed infra-red remote control of the utility model exchanges start and ac dump device, by voltage-stabilized power supply circuit, remote signal Acquisition Circuit, keep signal acquisition circuit, signal transformation circuit, executive circuit etc. and form.Voltage-stabilized power supply circuit provides power supply to complete machine.That the negative pulse string of the band coded message that the remote signal Acquisition Circuit is sent telepilot here carries out is anti-phase, send shaping circuit after the filtering.Keep signal acquisition circuit and be made up of mutual inductor and rectifier cell, when electrical work, this circuit send shaping circuit with the induced electromotive force that mutual inductor produces after rectification.Shaping circuit carries out above-mentioned two signals to send executive circuit after the shaping, the adhesive of pilot relay and release, thus reach the purpose that remote control exchanges start and ac dump.
The utlity model has safety, energy savings, the prolongation electrical equipment beneficial effect in serviceable life.
Description of drawings
Accompanying drawing is circuit theory diagrams of the present utility model.
Embodiment
Infra-red remote control exchange start and ac dump device by voltage-stabilized power supply circuit (1), remote signal Acquisition Circuit (3), keep signal acquisition circuit (2), signal transformation circuit (4), executive circuit (5) etc. and form.
Voltage-stabilized power supply circuit (1) provides power supply to complete machine.
Remote signal Acquisition Circuit (3) is made up of infrared receiving terminal HD, phase inverter F1, diode D2, filter capacitor C1 and resistance 1.The input end of the output terminal of infrared receiving terminal HD and phase inverter F1 joins, and the positive pole of the output terminal of phase inverter F1 and diode D2 joins, and the negative pole of diode D2 send shaping circuit after inserting filter capacitor C1 and resistance R 1 over the ground.
Keeping signal acquisition circuit (2) is made up of mutual inductor L and rectifier cell D1.One of connecting in two power leads of electrical equipment is passed mutual inductor L, the end ground connection in two lead-in wires of mutual inductor L, the other end send shaping circuit through rectifier cell D1.
Shaping circuit (4) carries out above-mentioned two signals to send executive circuit after the shaping, the adhesive of pilot relay J and release,
The normally opened contact of the relay J in the executive circuit (5) seals in the power supply of remote control electrical appliance.
When pressing any key on the telepilot facing to infrared receiving terminal HD, the output terminal of infrared receiving terminal HD is exported the negative pulse string of a string band coded message, after, filter capacitor C1 filtering anti-phase, phase inverter F2, the F3 shaping through phase inverter F1, output terminal at phase inverter F3 gets a high level, make triode V conducting, relay J adhesive, the normally opened contact closure of relay J, remote control electrical appliance gets electric, and this moment, remote control electrical appliance was in holding state.After unclamping remote controller key, because the energy storage effect of filter capacitor C1, the adhesive of relay J will be kept a period of time and (change the capacity of filter capacitor C1 or the resistance of resistance R 1, the length that scalable is held time), press the start button on the telepilot this moment again, remote control electrical appliance just can be started shooting, and has realized that so just remote control exchanges the function of start.
After remote control electrical appliance exchanged start, mutual inductor L produced induced electromotive force, after D1 send phase inverter F2, F3 shaping, got a high level, triode V conducting at the output terminal of phase inverter F 3.After this, as long as remote control electrical appliance work, triode V will keep conducting.
When the remote control electrical appliance remote-control closedown, or timing shutdown, or no signal when shutdown, electric current by electrical equipment reduces, and the induced electromotive force that mutual inductor L produces reduces phase inverter F3 output low level, triode V ends, relay J discharges, and the normally opened contact of relay J disconnects, and has so just realized the function of remote control ac dump.
Claims (2)
1, a kind of infra-red remote control exchanges start and ac dump device, by voltage-stabilized power supply circuit, the remote signal Acquisition Circuit, keep signal acquisition circuit, signal transformation circuit, executive circuit is formed, it is characterized in that described remote signal Acquisition Circuit is by infrared receiving terminal HD, phase inverter F1, diode D2, filter capacitor C1 and resistance R 1 are formed, the input end of the output terminal of infrared receiving terminal HD and phase inverter F1 joins, the positive pole of the output terminal of phase inverter F1 and diode D2 joins, and the negative pole of diode D2 send shaping circuit after inserting filter capacitor C1 and resistance R 1 over the ground.
2, exchange start and ac dump device according to the described infra-red remote control of claim 1, it is characterized in that the described signal acquisition circuit of keeping is made up of mutual inductor L, rectifier cell D1, one in two power supply lead wires of connection remote control electrical appliance is passed mutual inductor L, and the signal that mutual inductor L is produced send shaping circuit after rectification.
