Problems solved by technology

Its shortcoming is: the connection mode of the relay contact and the control electrical appliance is a single-control connection, and the controlled electrical appliance is directly controlled by the relay contact, so that only the remote control transmitter can be used to control the on-off of the electrical power supply

Abstract

The invention relates to a fixed-time wireless remote control multiway switch which comprises a transmitting circuit and a receiving circuit. In the transmitting circuit: a high electrical level is generated by an instant pulse generating circuit for triggering a fixed-time pulse generating circuit; the fixed-time pulse generating circuit transmits the high electrical level in fixed time to be taken as the input signal of a final pulse forming circuit after receiving the high electrical level; the final pulse forming circuit is responsible for triggering a transmitting module which transmits signals to the receiving circuit. In the receiving circuit, a power part provides electricity for the whole receiving circuit; a pulse receiving and electrical level transforming part is responsible for receiving the signal transmitted by the transmitting circuit and then decoding the signal after demodulating and transmitting the decoded signal to a drive circuit; the drive circuit drives a relay to work; after the relay is connected, an electricity-using apparatus works; if the relay is disconnected, the electricity-using apparatus does not work. The invention achieves the purposes of multiway real-time control, fixed-time control and wireless ratio-frequency control of the switch.

Description

technical field [0001] The invention relates to a switch device in the technical field of electronic devices, in particular to a timing wireless remote control multi-channel switch. Background technique [0002] At present, there are remote control switches and timer switches on the market, but multi-way switches with remote control and timing functions are rare. All the way to control the switch, when the user presses the button on the remote control, the oscillating circuit composed of 555 will continue to output the oscillating wave. The transmitter outputs the shock wave carrier. After the receiving head receives the signal, the output is sent to the input terminal of the LM567 universal tone decoder, and the LM567 processes the signal, separates the control signal, and then controls the relay through the triode. And this circuit has many disadvantages, such as: only one way of control can be realized, and the remote control is always emitting signals during the operat...
