Description

technical field [0001] The invention relates to a novel remote control system. Background technique [0002] At present, the products with remote control function on the market are mainly remote control products such as model airplanes, sea models and car models, such as: remote control airplanes, remote control cars and remote control speedboats and so on. Most use simple fixed-code instructions. There are many brands of integrated circuits with simple fixed codes, the functions are basically the same, and they can be replaced with each other, that is, one-to-one wireless control cannot be realized, and there are potential safety hazards. [0003] Such as figure 1 and figure 2 Shown is a structural schematic diagram of a remote controller and a receiver in the prior art. [0004] The prior art remote controller 100 is composed of a transmitting antenna 110, a high-frequency signal generating circuit 120, a command signal modulation circuit 130, a high-frequency signal ...

AI Technical Summary

Problems solved by technology

[0006] In the prior art, because the simple fixed encoding circuit 150 and the simple fixed decoding circuit 260 are used, a large number of solidified same instructions are used, the encoding is simple, the instructions are few, and the remote control operation requirements of more functions cannot be met, and the remote control function is single and cannot be upgraded. And reuse, many remote control functions are idle, which will cause a waste of resources

When multiple remote controllers in the same frequency band work, or when other devices interfere with the same frequency, the remote control execution devices cannot work normally, and they are all out of control. Usually, the receiver will cause channel congestion, resulting in paralysis of remote control operation and loss of control.

Such a remote control system can only be applied to toys. If it is applied to automation equipment, smart home appliances or manned remote control facilities, it will endanger human life and property safety.
