Abstract
The utility model relates to an infrared remote controlled switch on a walls, which belongs to the switches on walls. The utility model is characterized in that a circuit uses capacitance dropping voltage and 7805 stabilized voltage to provide stabilized +5 DC voltage for the whole circuit; an infrared receiver is used to receive remote control signals; a single-chip computer drives a trigger circuit CF based on the received signals, and the on-off of a bidirectional thyristor is controlled to light turn on or turn off the light. The utility model has the advantages that the switch on walls has the function of remote control, and the on-off of the light can be carried out by remote control.
Description
The utility model belongs to switch on wall.
The present switch on wall that uses, when the open and close electric light, the need people directly presses button with hand before going to switch, and is very inconvenient sometimes.
The purpose of this utility model is to provide a kind of infrared remote control switch on wall, makes switch on wall have distant control function, can carry out remote control and turn on light or turn off the light.
For achieving the above object, the technical scheme that the utility model is taked is: capacitor C 1 is in parallel with resistance R 1, commutation diode D1, D2, D3, D4 is connected into bridge rectifier circuit, the two series connection, the input end 1 of its direct current output point A and regulator block 7805 joins, 7805 output terminal 3 is connected to the VCC end of single-chip microcomputer MPU, 3 ends of infrared remote receiver UR, 1 end of trigger circuit CF, the positive pole of the D of light emitting diode, the input end IN1 of single-chip microcomputer MPU links to each other with 1 end of infrared remote receiver UR, the output terminal OUT1 of single-chip microcomputer MPU links to each other with R3 with resistance R 2, the other end of R2 is connected with 2 ends of trigger circuit CF, the other end of R3 is connected with the base stage of triode G, triode G links to each other with resistance R 4, the other end of R4 is linked the negative pole of light emitting diode D, 4 ends of trigger circuit CF and the control utmost point of bidirectional triode thyristor T join, and voltage dependent resistor (VDR) MV is connected in parallel on the both positive and negative polarity of bidirectional triode thyristor T, and hand control switch key K is connected with the input end IN2 of single-chip microcomputer MPU, LAMP is the load exit, connection terminal L, N; Also can 1 or 2 element circuit U1 be can connect again, duplex or three teleswitches constituted at output terminal, the input end of single-chip microcomputer MPU.
The utility model principle of work:
1. using capacitance decompression provides+5V voltage:
C
1, R
1Constitute the capacitance decompression device, by bridge rectifier D
1-D
4Interchange is become direct current.Through C
2, C
3Filtering, 7805 voltage stabilizings provide stable+5V DC voltage.
2. distant control function
Receiver of remote-control sytem UR receives the remote control coding signal, and sends it to single-chip microcomputer, and single-chip microcomputer is controlled according to coded signal and turned on light, turns off the light and light modulation.
3. the output signal of single-chip microcomputer output terminal OUT drives trigger circuit CF, thereby realizes turning on light, turning off the light and light modulation.
The utility model has the advantages that: make switch on wall have distant control function, can carry out remote control and turn on light or turn off the light.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further details.
Fig. 1, the utility model circuit diagram,
Fig. 2, the utility model embodiment two circuit diagrams.
