Problems solved by technology
[0002] Existing remote control devices generally use infrared remote control, bluetooth remote control, radio frequency remote control and other principles to realize the transmission and reception of remote control signals, and use professional hardware platforms for remote control operations. The circuits of these hardware platforms are complex and require quite professional design and maintenance. Therefore, it is difficult to maintain in the later period, which is not conducive to popularization and use. In addition, the infrared remote control method and the Bluetooth remote control method have the problem of short transmission distance, while the Bluetooth remote control method is easy to be interfered, the signal is unstable, and the transmission distance is short. However, the radio frequency remote control has the problem that the frequency band standard is not uniform and it is easy to be interfered
