In conjunction with accompanying drawing 1-6, the utility model is done further to describe:

The main radio transmitter of the utility model, wireless receiving circuit, single-chip microcomputer and SCM peripheral driving circuit are formed; Described single-chip microcomputer adopts the pic12f629 single-chip microcomputer of PIC series; Wherein the output signal end of single-chip microcomputer links to each other with the SCM peripheral driving circuit; The wireless signal input end of single-chip microcomputer links to each other with wireless receiving module, and decoding work is accomplished by single-chip microcomputer; Described SCM peripheral driving circuit drives lighting device through bidirectional triode thyristor B1; Described radio transmitter is made up of PT2262 coding circuit and 315MHz radio transmitter, and wireless signal is through the emission of coding back; Described wireless receiving circuit is made up of Armstrong circuit and signal amplification circuit, and wireless signal is received by Armstrong circuit, is amplified by the signal amplification circuit that with LM358 is core, through the single-chip microcomputer decoding processing again.

The utility model is installed in the 3807 oil resistant rubber shell shells, and on shell, settles a plurality of lighting device control buttons.The SCM peripheral driving circuit links to each other with lighting device, and through bidirectional triode thyristor control lighting device.When pressing control knob, single-chip microcomputer can be controlled opening and turn-offing of respective illumination devices.

Concrete is: the telepilot sheathing material adopts 3807 oil-resistant rubber slabs, and this rubber hardness is higher, anti--30～100 ℃ greasy dirt, the site environment in very suitable oil recovery front.

The hardware designs of radio transmitter:

Radio transmitter is made up of PT2262 coding circuit (as shown in Figure 2) and 315MHz radio transmitter (shown in Fig. 1-a).As shown in Figure 2, when radio transmitter is worked, at first export a group coding to " OUT " end according to its encoding state by PT2262, " OUT " end links to each other with the base stage of triode Q5 among Fig. 1 (a).When " OUT " end is high level, the Q5 conducting, circuit sends the signal of 315MHz; When " OUT " end was low level, Q5 ended, and circuit does not send signal.

PT2262 is the general coding-decoding circuit of low-power consumption low price that a kind of CMOS technology of Taiwan Pu Cheng company production is made; PT2262 can have 12 (A0-A11) three-state address end pins (unsettled, connect high level, connect low level) at most; Combination in any can provide 531441 address codes; PT2262 can have 6 (D0-D5) data terminal pins at most, and the address code of setting and numeric data code are exported from 17 pin serials, can be used for the wireless remote control radiating circuit.

With reference to accompanying

drawing

3 and 4, the coded signal that coding chip PT2262 sends by: address code, numeric data code, synchronous code are formed a complete code word, if transmitting terminal presses & hold always, coding chip also can be launched continuously.When transmitter did not have button to press, PT2262 disconnected power supply, and its 17 pin is a low level; So the high frequency transmission circuit of 315MHz is not worked; When button was pressed, PT2262 got the electrician and does, and its 17th pin is exported modulated serial data signal; When 17 pin are the high frequency transmission circuit starting of oscillation of 315MHz between high period and launch the constant amplitude high-frequency signal; When the high frequency transmission circuit failure of oscillations of 17 pin for 315MHz during low flat, so high frequency transmission circuit is received the digital signal of controlling in the 17 pin output of PT2262 fully, to be equivalent to degree of modulation be 100% amplitude modulation thereby high-frequency circuit is accomplished amplitude keying (ASK modulation).

PT2262 is 18 pin; The DIP encapsulation, the PT2262 coding principle: each group code that PT2262 sent is made up of 12 AD sign indicating numbers (address code adds numeric data code, adds 4 bit data sign indicating numbers such as 8 bit address sign indicating numbers); Each the content of encoding is determined by the connection status of A0-A11 and D0-D5 pin respectively; The connection status of each pin has " 0 " respectively, " 1 ", " unsettled " three kinds.12 bit address sign indicating numbers and 8 bit data code character Chengdu represent that with the width different pulse two burst pulses are represented " 0 "; Two broad pulses are represented " 1 "; A burst pulse and a broad pulse are represented " F " " unsettled " of address code just.Three kinds of bit codes are as shown in Figure 3 respectively." a " clock period of expression among the figure.

There is synchronous code to separate between every group of character code, as shown in Figure 4.If so we when decoding with scm software, as long as program is judged synchronous code, carry out pulse width identification to the character code of back then and get final product.

(3) wireless receiving hardware designs

Wireless receiving circuit is by Armstrong circuit (as shown in Figure 5), and signal amplification circuit (as shown in Figure 6) is formed.Wireless signal is at first received by Armstrong circuit, is amplified by the signal amplification circuit that with LM358 is core again.

(4) design of single-chip microcomputer and peripheral circuit thereof

Single-chip microcomputer in the unit controls adopts the pic12f629 single-chip microcomputer of PIC series, and packing forms: PIC12F629 is the DIP16 encapsulation.

The single-chip microcomputer pin assignment: the 2nd pin is an output signal end, links to each other with the SCM peripheral driving circuit; The 6th pin is the wireless signal input end, links to each other with wireless receiving module.Decoding work is accomplished by single-chip microcomputer.

Shown in Fig. 1 (b), the SCM peripheral driving circuit drives lighting device through bidirectional triode thyristor B1.When the 2nd pin is high level, optocoupler Q ₅Conducting, under the effect of 220V civil power, R ₄, R ₅, R ₁₆And lighting device forms loop, R ₁₆On voltage drop make bidirectional triode thyristor B1 conducting, lighting device is lighted.When the 2nd pin is low level, optocoupler Q ₅Turn-off, bidirectional triode thyristor B1 turn-offs, and lighting device extinguishes.
