Problems solved by technology

[0005] Most household appliances have different remote controls to achieve specific functions. If there are too many remote controls, you will forget which remote control controls which electrical appliance. Sometimes you search everywhere to find the remote control of a certain electrical appliance. Not only is it easy to cause a waste of resources, but it also affects people's daily life, especially sometimes when they come back from get off work and fall asleep when they are tired, they suddenly find that the lights in the living room and toilet are still on, but they don't want to get up and turn them off one by one.

Embodiment

[0019] A multi-channel radio remote controller, including a wireless transmitting system, a wireless receiving system and a power supply;

[0020] The wireless transmitting system includes a key coding and a transmitting module, the key coding includes a key part and an encoder, and the key part adopts an independent key and is composed of four independent keys, a diode and an LED working indicator light. In the whole circuit, Independent buttons, resistors, and diodes are connected in parallel to form a simple button switch system, which converts the switch information of the buttons into high and low levels to represent; the encoder uses a traditional remote control dedicated encoder -- the transmitter module described in PT2262 The 315 transmitter module is used, and the 315 transmitter module adopts an external connection mode. Its three pins are ground, power supply and data interface, and there is an antenna interface. The working voltage is 12V;

Description

technical field [0001] The invention relates to a signal transmission device, in particular to a radio remote controller. Background technique [0002] Radio technology is a technology that uses oscillators to generate radio waves to propagate signals. The main working principle of radio technology is that firstly, changes in the strength of the current in the conductor will generate radio waves. When radio waves propagate through space and reach the signal receiving end, radio waves The electromagnetic field change caused by the radio wave will generate an electromagnetic current in the conductor, and finally the original information is extracted from the current change by demodulating the electromagnetic wave, and the purpose of transmitting the radio signal is achieved. [0003] The initial development of radio from electron tube to transistor, and transition to integrated circuit, and then experienced the process from short wave to ultrashort wave, and then to microw...
