TV Remote Launch part
Remote control is a wireless transmitter device, through the modern digital coding technology, the key information encoding, through the infrared diode light emission, why the remote control can control the TV? Specifically by the remote control manufacturers Yakuan watches for your detailed introduction.
Light wave by the receiver of the infrared receiver will receive the infrared signal into electrical signals into the processor to decode, demodulate the corresponding instructions to control the set-top box and other equipment to complete the required operational requirements.
The passenger door remote control is the latest technology to decode the code to flash the way to control the door pump solenoid valve to achieve the purpose of switching automatic doors. For the bus (bus, CMB) remote control open, off the door, to avoid the driver every time you need to open the door to the trouble. The main components of the transmitter part of the remote control for the infrared light-emitting diodes. It is actually a special  light-emitting diode, because its internal material is different from ordinary light-emitting diodes, so at both ends of the application of a certain voltage, it will be issued  infrared rather than visible light. How to quickly determine the infrared remote control is good or bad? Infrared remote control into people's lives have been many years, because the infrared is invisible light, when the home appliances from remote control, we often can not tell in the end is the electrical problem or remote control problem. Here to teach you a best way to use.

We now use most of the phone with a camera function. This camera is open after the remote control launch tube shooting, do not point to take pictures, just through the camera to see the remote control tube. If you press the remote control of a button to see the launch tube bright white, it shows that the remote control is good, can be fired.
If there is no bright white, we must check the remote control. Most of the battery is low or no electricity. There is also a battery spring card with poor rust contact. Moreover, it is artificially fell, causing the launch tube or crystal and other electronic components open welding, we just open the shell can be carefully observed where the open welding. Found after the soldering iron can be a good!
According to years of experience, the TV receiver's circuit is almost zero probability, the majority of the remote control bad. And air conditioning on the contrary, air conditioning is the most vulnerable to the bad circuit, air conditioning remote control bad not much. I hope that the small writers can understand these, to bring you convenience! Since the infrared remote control signal is not able to penetrate the wall, it is not necessary to have different remote control frequencies or codes for each set (transmitter and receiver) as in the case of a wireless remote control for designing a home appliance, It will partition the wall control or interference with the neighbors of household appliances), so similar products infrared remote control, you can have the same remote control frequency or coding, and no remote control signal "string" situation. This is for the mass production and in the popularity of infrared on the home appliances provide a great convenience. Of course, very few users to the two brands of the same infrared receiver equipment at home with the same range, such as two next to the same type of TV (resulting in a remote control can simultaneously control two devices)
But also because of the direct characteristics of infrared, infrared communication technology is not suitable for transmission barriers more places, this occasion generally use radio communication technology or Bluetooth technology. Infrared communication technology in most cases, the transmission distance is short, the transmission rate is not high.
