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; Single-chip microcomputer 5,6 pin are connected with the clock circuit that Y2 forms.

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 controlled device under the control of single-chip microcomputer is the wireless signal of 433.92MHZ.

The structure of photosensitive sensing circuit is: single-chip microcomputer input end 8 pin are connected with one-chip machine port 7 pin with divider resistance R5 by photoresistance RDS, and the dividing point of photoresistance and divider resistance is by capacitor C 10 ground connection; During the light deepening, it is big that photoresistance RDS resistance becomes, and to single-chip microcomputer 8 pin input sample signals, single-chip microcomputer is promptly controlled the remote signal radiating circuit and sent start signal to controlled device, makes itself and power connection.

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.Be used for timing shutdown signal to single-chip microcomputer input selection.

This example is provided with 8 grades of time selection circuits, and concrete structure is: four port ones, 4,1,2,3 pin of single-chip microcomputer, four switch S 1, S2, S3, the S4 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 5, S6, S7, the S8 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 signal of photosensitive sensing circuit, after controlled device sends wireless start signal, setting by software, when reaching the shut-in time of setting, single-chip microcomputer can send shutdown signal to controlled device again automatically again, and the setting of this example is:

When connecting switch S 2, S3, S4, S5, S6, S7, S8 respectively, the shutdown signal that controlled device can be sent by single-chip microcomputer after connecting 1 hour, 2 hours, 3 hours, 7 hours, 6 hours, 5 hours, 4 hours is respectively closed automatically;

And when connecting switch S 1, after controlled device is opened, just be in on-state always;

This remote control transmitter button inputting circuits is provided with and sends learning key S3, is used for sending to the single-chip microcomputer input instruction of learning signal:

Single-chip microcomputer 3 pin are by sending learning key S3 ground connection; This key also has a function to be: when length was pressed this key, single-chip microcomputer may command remote signal radiating circuit sent erasure signal, is used to delete the original learning signal of controlled device.

This device before use, if desired, to make controlled device that this remote control transmitter is carried out sign indicating number is learnt earlier, detailed process is: the reception learning key of pressing controlled device earlier, the pilot lamp of this equipment dodges slowly, expression enters learning state, in 12 seconds, short again transmission learning key by this remote control transmitter, this remote control transmitter promptly sends the coded signal that it will be learnt 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.

This remote control transmitter can be fixed on the body of wall, during use, configures the shut-in time interval of selection earlier by the on ﹠ off switch of timing circuit; When the colour of sky grew dark, remote control transmitter automatically i.e. emission starting-up signal was connected the controlled device power supply, launched remote-control closedown signal at stop controlled device power supply when reaching selected time interval again.When the load that is connected with controlled device is electric light, promptly can open automatically at dark, close automatically again when reaching selected time.
