Four-way wireless remote control switch

Abstract

The invention relates to a four-way wireless remote control switch. The four-way wireless remote control switch comprises a wireless emitting system and a wireless receiving system, wherein the wireless emitting system comprises a key module, an encoding module and a wireless emitting module; the wireless receiving system comprises a wireless receiving module, a decoding module and a relay module. According to the four-way wireless remote control switch, firstly, the bit number of a required control circuit is input through a key circuit, an encoding circuit is simultaneously started to generate a coded pulse signal carrying address coding information and switch state information, and the signal is emitted out through a wireless emitting circuit; a wireless receiving circuit carries out encode address confirmation on the received coded pulse signal through a decoding circuit and confirms whether an encode address is the address of the remote control switch; if the encode address is the address of the remote control switch, the decoding circuit generates corresponding output signals to control a relay circuit and a switch circuit to work, but if the encode address is not the address of the remote control switch, the decoding circuit does not work, the relay circuit does not respond, and the switch circuit does not do any action.

Description

technical field [0001] The invention relates to the field of remote control switches, in particular to a four-way wireless remote control switch. Background technique [0002] Due to the continuous emergence of new large-scale remote control integrated circuits, the remote control technology has developed rapidly. At present, the commonly used remote control method in the field of wireless remote control is mainly infrared remote control. By transmitting infrared rays to the receiver of the electrical appliance, the control of the electrical appliance is realized, which brings convenience to people's life. However, an obvious defect of the infrared remote control is the transmitter. The distance between the receiver and the receiver is too short, and there can be no obstacles. Therefore, no matter in daily family life or industrial operations, such as the working place of mining machinery, the environment is harsh, the visibility is low, and there are many obstacles. Obviou...

At present, the commonly used remote control method in the field of wireless remote control is mainly infrared remote control. By transmitting infrared rays to the receiver of the electrical appliance, the control of the electrical appliance is realized, which brings convenience to people's life. However, an obvious defect of the infrared remote control is the transmitter. The distance between the receiver and the receiver is too short, and there can be no obstacles. Therefore, no matter in daily family life or industrial operations, such as the working place of mining machinery, the environment is harsh, the visibility is low, and there are many obstacles. Obviously, infrared remote control cannot realize the control operation of machinery, and cannot meet people's needs very well.
