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 controlled device is the remote control socket with learning functionality, so housing is provided with the transmission learning key L.D.KEY that is connected with the single-chip microcomputer input end, is used for sending to the single-chip microcomputer input steering order of wireless remote control learning signal.

Single-chip microcomputer 10 pin are by this keyed jointing ground, single-chip microcomputer 10 pin also are connected with+3 volts of direct supplys, generally, + 3 volts of direct supplys are powered to single-chip microcomputer 10 pin, when this transmission learning key 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.

These routine magnetic induction switch parts are tongue tube K1, and single-chip microcomputer 7 pin are by K1 ground connection;

Also being provided with one is the magnetic induction body that divides body structure with the magnetic induction switch parts, and this routine magnetic induction body is a permanent magnetic iron block.

When magnet piece when the tongue tube K1, the closed ground connection of K1 is to the single-chip microcomputer input low level, when magnet piece during away from tongue tube K1, K1 opens, and it is the wireless start signal of 433.92MHZ that single-chip microcomputer can send carrier wave to controlled device by the remote signal radiating circuit in view of the above.

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.

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 level variable signal of magnetic induction switch parts tongue tube K1, after controlled device sends 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 switch S 3, S4, S5, S6, S7, S8, S9 respectively, the shutdown signal that controlled device can be sent by single-chip microcomputer 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;

When this device is installed, the housing that single-chip microcomputer and aforementioned circuit are housed is fixed on the doorframe, magnet piece is fixed on can be near on the pivoting door body of housing under the state of closing the door, like this when opening the door, because magnet piece leaves housing, tongue tube in the housing promptly breaks away from the effect of magnet piece, single-chip microcomputer is received the magnetic induction switch signal of this variation, promptly according to the setting of software, send the wireless start signal of 433.92MHZ by the remote signal radiating circuit to controlled device, the switch of controlled device is opened.

After controlled device was opened, remote control transmitter can be launched shutdown signal every certain hour and controlled device be closed (also can make controlled device be in normally open according to selection) automatically according to the signal of time selection circuit input again.

This routine controlled device is the remote circuit socket, so when the usefulness electric loading that is connected with this supply socket is electric light, will light automatically when opening, when reaching selected time, can close automatically again.

This device before use, to make controlled device that this remote control transmitter is carried out sign indicating number is learnt earlier, detailed process is: long earlier pressing more than the reception learning key 6S of controlled device, the pilot lamp of this controlled device dodges slowly, expression enters learning state, in 12 seconds, press the transmission learning key L.D.KEY of this remote control transmitter again, _ remote signal radiating circuit promptly sends the remote control coding signal that it will be learnt to controlled device under the control of single-chip microcomputer, 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.
