Embodiment (referring to Fig. 2)

Embodiment 1

This example adopts the BM22P02 single-chip microcomputer that is contained in the housing to make central control unit; Its 5 pin is connected with the clock circuit that Y2 forms with 6 pin, and by+the 3V DC power supply.

Also be provided with the remote signal radiating circuit in the housing, the remote signal radiating circuit is made up of triode G1 and peripheral circuit, the Y1 SAW (Surface Acoustic Wave) filter that connects in the base loop can produce the 433.92MHZ carrier frequency, its base stage is connected with single-chip microcomputer output terminal 9 pin, and being used for sending carrier wave to controlled device under the control of single-chip microcomputer is the wireless signal of 433.92MHZ.

This routine timing circuit is made up of a plurality of on ﹠ off switches: the n of a single-chip microcomputer port is connected with single-chip microcomputer first port outside this n port by n on ﹠ off switch of first group respectively, and this n port also passes through n on ﹠ off switch of second group respectively and is connected with single-chip microcomputer second port outside this n port simultaneously.

This example is provided with 8 grades of time selection circuits, is used for the timing shutdown signal of selecting to the single-chip microcomputer input.Concrete structure is: four port ones, 4,1,2,3 pin of single-chip microcomputer, four switch S 2, S3, S4, the S5 by first group respectively are connected with 12 pin of single-chip microcomputer; Simultaneously these four port ones, 4,1,2,3 pin of single-chip microcomputer also respectively four switch S 6, S7, S8, the S9 by second group be connected with 13 pin of single-chip microcomputer; Two groups of 8 switches are selected 8 grades of rotary switches for use.

The function of 8 grades of time selection circuits is the selections by 8 on ﹠ off switches, can import different timing shutdown signals to single-chip microcomputer, when single-chip microcomputer receive the instruction of opening controlled device, after controlled device has sent wireless start signal, setting by software, the timing shutdown signal that can import according to time selection circuit automatically sends shutdown signal to controlled device again behind the certain hour of being separated by, the setting of this example is:

When connecting on ﹠ off switch S3, S4, S5, S6, S7, S8, S9 respectively, the signal that controlled device can be sent by this remote control transmitter after connecting 2 minutes, 4 minutes, 6 minutes, 20 minutes, 15 minutes, 10 minutes, 8 minutes is respectively closed automatically;

And when connecting switch S 2, after controlled device is opened, just be in on-state always;

Button inputting circuits is provided with and sends learning key S1, single-chip microcomputer 8 pin are by this keyed jointing ground, generally, single-chip microcomputer 8 pin are high level, when this transmission learning key S1 of pressing in short-term on the remote control transmitter, promptly import a low level to single-chip microcomputer 10 pin, single-chip microcomputer is received the coded signal that this instruction promptly will be learnt to the controlled device emission by the remote signal radiating circuit.If long, also can send the remote signal of deleting the original coding of controlled device according to software setting by this key.

Button inputting circuits is provided with start key S1, and OFF closing key S0.

The key of wherein starting shooting adopts same key LEARN/ON key S1 to operate with the transmission learning key.

If controlled device need be learnt this remote control transmitter, can press the reception learning key of controlled device earlier, the pilot lamp of this equipment dodges slowly, expression enters learning state, in 12 seconds, presses the transmission learning key S1 of this remote control transmitter again, this remote control transmitter promptly sends learning signal to controlled device, the pilot lamp of controlled device by dodge slowly-extinguish-grow bright, the expression learning success, this controlled device can be accepted the control of this remote control transmitter later on.

During use, short start key S1 by this remote control transmitter, the remote signal radiating circuit promptly sends the wireless start signal of 433.92MHZ to controlled device, and controlled device is opened.If long, then can open controlled device by dimming mode according to software setting by this key.

After controlled device was opened, single-chip microcomputer again can be according to the signal of time selection circuit input, and emission remote closing signal is closed controlled device (comprising according to selecting to make controlled device be in normally open) automatically behind certain hour.

Except that time selection circuit, this example also can adopt the closing key S0 of button inputting circuits manually to shut down, and is used for sending to controlled device to the single-chip microcomputer input instruction of off signal; After controlled device is opened, press this key at any time, remote control transmitter all can send off signal to controlled device, and remote host is closed, and makes the existing automatic shutdown function of this remote control transmitter, and manual shutdown function is arranged again.
