Abstract

The utility model relates to an infrared remote control one-way delay switch, which belongs to the field of the manufacture of delay switches. The utility model is characterized in that the utility model comprises a single-chip computer, an infrared receiver, and a thyristor which is connected in series to a load circuit, wherein, the core of the single-chip computer is 78P152B; the power terminal of the infrared receiver is connected with a rectification filtering and voltage stabilizing circuit, the input of the infrared receiver is an infrared remote control signal, and the output terminal of the infrared receiver is connected with the terminal 4 of the single-chip computer; the thyristor is controlled by both terminals 6, 7 of the single-chip terminals. The utility model can be used for the switching control of lamps in corridors and entrance halls. The utility model can be controlled by remote control or by hands. When the power of the lamp is switched on, the lamp is extinguished after two minutes of time delay under the control of the single-chip computer, and the lamp can also be controlled by hands for instant extinguishment.

Description

Infrared remote control formula single channel delay switch

A kind of infrared remote control formula single channel delay switch belongs to the delay switch field.

At present the delay switch of use such as corridor, entrance hall is to adopt manually to control rather than remote control, can Time Delay Opening but can not manual-lock.

The purpose of this utility model is to provide the monolithic processor controlled infrared remote control formula of a kind of usefulness single channel delay switch to address this problem.

Of the present utility model being characterised in that, it contains: chip is the single-chip microcomputer IC2 of 78P152B, power supply termination rectifying and wave-filtering and voltage stabilizing circuit, be input as infrared remote-controlled signal and output meets the infrared remote receiver IC1 of 4 ends of single-chip microcomputer IC2, and be controlled by 7,6 two ends of single-chip microcomputer IC2 and be serially connected with controllable silicon BCR in the load circuit through current-limiting resistance R1.5 ends at single-chip microcomputer IC2 are connected to a hand push button K over the ground.

Evidence: it can be delayed time after the load circuit conducting and cut off in 2 minutes again, both remote-controlled also can be manual.

In order in conjunction with the embodiments the utility model to be elaborated below, show as follows employed accompanying drawing number of present specification and title brief introduction:

Fig. 1 is the circuit theory diagrams of infrared remote control formula single channel delay switch.

Embodiment:

Ask for an interview Fig. 1, circuit form and annexation as above-mentioned, controllable silicon BCR BT136, IC1 is an infrared remote receiver, its model is TSOP1838.Its input is from the infrared remote-controlled signal of remote controller, and 4 ends of output and single-chip microcomputer IC2 link to each other.220V AC power power end to infrared remote receiver IC1 after halfwave rectifier, voltage stabilizing and filtering is powered.5 ends of single-chip microcomputer IC2 are connected to a hand push button K over the ground, and LED manually controls the demonstration light-emitting diode.Controllable silicon BCR exchanges serial connection through electric light JZ2 with 220V.The control end of controllable silicon BCR is controlled by 7 ends of single-chip microcomputer IC2 after resistance R 1.6 ends of single-chip microcomputer are realized its detection effect to supply frequency through diode D3, D2, so that the angle of flow of controllable silicon BCR is controlled in real time.

Infrared remote receiver IC1 just sends the connection request of controllable silicon BCR to 4 ends of single-chip microcomputer IC2 through output behind the infrared remote-controlled signal of receiving from the outside.Single-chip microcomputer IC2 judge errorless after, just go to make controllable silicon BCR conducting through 7 ends, electric light JZ2 is connected under single-chip microcomputer IC2 control and delay time and turned off the light in 2 minutes.
