Five, embodiment
Circuit of the present invention can be divided into remote controlled transmitting circuit and remote-control receiving circuit; Wherein the remote controlled transmitting circuit composition diagram is as shown in Figure 1: this circuit adopts single chip computer AT MEGA16L as control unit; The PT2262 chip receives Single-chip Controlling; Receive associated control signals such as recording playback music, remote controlled travelling, conversion decorative lamp color, be modulated into the ASK signal then and give the radio-frequency transmissions circuit and go out from antenna transmission.The radio-frequency transmissions circuit adopts 315MHz sound table resonator SAW, and frequency stability is high; Display circuit adopts the LCD circuit, and model is OCM12232,122 * 32 pixels, but display operation content.
The remote controlled transmitting circuit sketch map is as shown in Figure 2.
Remote-control receiving circuit partly is made up of control, radio frequency reception, servo circuit, music recording playback, light circuit etc.Receive and adopt the 315MHz Armstrong circuit, give PT2272-M6 chip with the signal after the mixing then, the signal that demodulation is come out is given single chip computer AT MEGA16L.The music recording and playback ic is selected compositions such as ISD25120 for use, and the duty that servo circuit is regulated PWM (pulse width modulation) signal through single-chip microcomputer is recently controlled the steering wheel circuit, controls transmission mechanism with steering wheel again, the angle adjustment travel direction of rotation.PWM is produced by ATMEGA16L, and the input of pwm control signal is a broad-adjustable periodic square wave pulse signal, and the cycle of square-wave pulse is 20ms.When the pulse duration of square wave changed, the angle of steering wheel rotating shaft changed, and the angle variation is directly proportional with pulse duration, has determined the left and right directions that goes.Relation between the output shaft corner of steering wheel and the pulse duration of input signal is as shown in Figure 4:
Light circuit is made up of the LED lamp of three kinds of colors of red, green, blue, and this color lamp is according to the principle of three primary colours, forms a colour changeable unit with three kinds of primary colours of red, green, blue.Three kinds of primary colours lamps are packed in the ground glass cover,, arrange in pairs or groups mutually, can show red, blue, green, purple, blue or green, yellow, white seven kinds of colors through dichromatism in three kinds of colors through the colour mixture effect of lampshade.
ATMEGA16L controls music circuit, light circuit, servo circuit respectively according to the order that demodulation is come out.Entire circuit is external+battery of 9V, provide+5V voltage stabilizing output with 78L05, and TPS76033 provides+3.3V output.
The remote-control receiving circuit sketch map is as shown in Figure 5: Fig. 5 remote-control receiving circuit sketch map software is made up of the program of single chip computer AT MEGA16L; Program compiles generation under the operating environment of ImageCraft ICCAVR, and through EasyPro L+ programmable device the hex burning file that generates is advanced in the ATMEGA16L chip.The program circuit of remote-control transmitting (reception) circuit is like Fig. 6, shown in 7.
