The peak wavelength for the infrared ray (light) that pipe issues is able to satisfy the requirement of infrared remote control between 880nm to 950nm.It is infrared distant
The principle of control is mainly: binary digital signal is modulated into the arteries and veins of a certain frequency using pulse time modulation (PPM) mode by transmitting terminal
Sequence is rushed, drives infrared-emitting diode work to launch signal in the form of light pulse driving circuit, receiving end
The light arteries and veins received is converted into electric signal, is demodulated, is reduced to using demodulator circuit is given after the processing such as amplification, filtering
It is exported after binary digital signal, thereby realizes required control.
It is attached to Digiplex in home electronics mostly at present, general remote control circuitry uses infrared remote control
Coding chip will be remotely controlled using remote controler, transmitting tube is equipped on remote controler, drive infrared emission two by driving circuit
Pole pipe work launches signal in the form of light pulse, is equipped on the receiver of home electronics and matches with transmitting tube
The reception pipe of conjunction.However, when cell voltage is lower, the voltage of traditional remote controler driving circuit battery during use
It is easily pulled low, signaling hair is made not go out, thus the phenomenon that generating remote control failure, the work of remote controler is unreliable.

Detailed description of the invention
Fig. 1 is the circuit diagram of remote controler driving circuit described in the utility model.
Fig. 2 is the circuit diagram using the specific embodiment of remote controler driving circuit.
Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Referring to Fig. 1, a kind of remote controler driving circuit described in the utility model, resistance R7, light emitting diode D1, capacitor
E1, triode Q1, resistance R5 and resistance R6.One end of resistance R7 and the anode of capacitor E1 are connected with power vd D, resistance R7
The other end be connected with the anode of light emitting diode D1.The cathode of light emitting diode D1 is connected with the collector of triode Q1.Electricity
Cathode, the emitter of triode Q1 and the one end of resistance R6 for holding E1 are grounded.The other end and triode Q1 of resistance R6
Base stage be connected and pass through resistance R5 and be connected with remote controller chip.
The model IR333 of light emitting diode D1, triode Q1 are triode 8050.
Resistance R5 is used for control signal current limliting, and making triode Q1, reason base current is not excessive and burn out.
Resistance R6 drop-down ground connection, goes to interfere, and guarantees that triode Q1 is in off state when without effectively control signal, improves
Reliability.
Resistance R7 is used to carry out current limliting to light emitting diode D1.
Triode Q1 is key element, determines whether light emitting diode D1 works.
Light emitting diode D1, that is, infrared-emitting diode, can issue infrared light, convert the electrical signal to when thering is electric current to flow through
Optical signal.
Capacitor E1 is electrolytic capacitor, supplements the energy content of battery, by battery when being effectively ensured chip reason diode D1 not working
Voltage pull-down and make chip reset.
If one end that resistance R5 is connected with remote controller chip is the port Transmit, the port Transmit connects remote control control
Chip, control signal is by port driving triode Q1 after resistance current limliting, so that light emitting diode D1 be made to work:
When the port Transmit is high level, triode Q1 conducting, light emitting diode D1 has electric current to flow through sending infrared light；Transmit
When port is low level, triode Q1 cut-off, light emitting diode D1 does not work.The signal of the port Transmit load is a certain frequency
The pulse train of rate, therefore the working condition of triode Q1 is conducting, cut-off, is connected, ends again again, light emitting diode D1 is issued
Infrared light reformed into the light pulse sequences of corresponding frequencies.
