Background technology
Infra-red remote control has simple in structure, easy to make, of low cost, strong antijamming capability, functional reliability height etc.
Series of advantages is the preferred remote control mode of short distance remote control, particularly indoor remote control.It is generally based on NEC agreements on the market
IR remote controller radiating circuit design, the collected signal of keyboard is encoded with NEC agreements.And pass through transmission circuit
Signal is sent.Remote control transmitter special chip much forms radiating circuit with HT6221, general home-use DVD,
VCD, sound equipment all use this coding mode.After transmitter presses key pressing, that is, there is remote control mode to send out, institute's different remote controls pressed key
Coding is also different.
Infrared remote control is as a kind of unidirectional infrared communication technology, because it is stable with performance, easy to use and at low cost
The features such as honest and clean, using very extensive in national defence, industrial production, household electrical appliance, security and daily life.So
And the problems such as traditional remote-controlled chip is there are pin is more, and peripheral circuit is complicated, and power consumption is higher.To reduce infrared remote control hair
The production cost of system is penetrated, the peripheral cell of infrared remote coding chip is reduced, the market competitiveness is improved, needs one kind in the market
The design of new infrared remote control coding chip reduces outer same number of elements, reduces packaging cost to greatest extent, realizes that low-power consumption is set
Meter.
The present invention is intended to provide a kind of repeating the programmable Infrared Remote-Control Sending circuit of erasable multisystem, remote control coding software
Realize that the programming of compatible 99% or more common infrared remote control format, peripheral circuit are simple.
Invention content
Technical problems based on background technology, the present invention for background technology there are the problem of, providing one kind can weigh
Multiple erasable multisystem may be programmed Infrared Remote-Control Sending circuit, and remote control coding software realization is compatible with 99% or more common infrared remote control
The programming of format, peripheral circuit are simple.
The radiating circuit of infrared remote control is to send out the infrared waves through ovennodulation using infrared light-emitting diode；It is infrared to connect
It receives circuit to be made of infrared receiving diode, triode or silicon photocell, the infrared light that they emit infrared transmitter is converted
For corresponding electric signal, then send post amplifier.Remote control technology is also known as remote control technology, refers to realizing to controlled object
Remote control is widely used in Industry Control, aerospace, field of household appliances.Infrared remote control is a kind of wireless, non-contact control skill
Art has strong antijamming capability, and information transmission is reliable, low in energy consumption, at low cost, easily the remarkable advantages such as realization, is set by all polyelectrons
Standby especially household electrical appliance are widely used, and are more and more applied in computer system.
Spectrum is located at except red light, and wavelength is 0.76~1.5 μm, and also longer than the wavelength of red light, such light is claimed
For infrared ray.Infrared remote control is a kind of control system for using infrared ray transmit information, and infrared remote control has anti-interference, electricity
Road is simple, and encoding and decoding is easy, small power consumption, advantage at low cost, and current almost all of video and audio frequency apparatus are all supported
This control mode.
Infrared remote control system structure infrared remote control system is broadly divided into modulation, transmitting and receives three parts.
Infrared emission may be implemented there are many kinds of chip at present in emission system, and different types of volume can be sent out according to selection
Code.Since emission system generally uses battery powered, this requires the power consumption of chip is very low, chip is designed as to locate mostly
In dormant state, just work when having by key pressing, can reduce in this way the crystal oscillator used in power dissipating chip should have it is enough resistance to
Physical shock ability cannot select common quartz crystal, usually Ceramics acoustic resonator, ceramic acoustic resonator accuracy not to have
Quartz crystal is high, but a usual point tolerance can be ignored.Infrared ray is launched by infrared light-emitting diode (LED),
Infrared light-emitting diode internal material and common light emitting diode difference, when its both ends applies certain voltage, what it sent out is
Infrared ray rather than visible light.
