Description of drawings

Accompanying drawing 1 is the structured flowchart of shuttlecock provided by the invention.

Accompanying drawing 2 is shuttlecock circuit catenation principle figure provided by the invention.

The specific embodiment

Be further described below in conjunction with accompanying

drawing

1 and 2 couples of the present invention of accompanying drawing:

As shown in Figure 1, comprise that main control chip STC12LE2052 control module, counting show play football number of times control module, acoustic luminous control module, fall on the ground detection and stop to count play football the number of times control module and the number of times input detecting circuit of playing football; Main control chip module is that STC12LE2052 piece is formed by peripheral 20 pin models, has signal storage, processing and control function; The counting display control module can totally show the number of times of playing football, and shows with miniature digitrons LED1-3W1; Acoustic luminous control module is controlled by main control chip; Falling on the ground the signal input testing circuit that detects the control and the number of times of playing football is finished by the button touch switch.

As shown in Figure 2, button touch switch S1 and S2 symmetry are installed in the shuttlecock bottom, during shuttlecock kicking, the stressed closure of switch, connect circuit, and to interrupt requests of single-chip microcomputer main control chip generation, the single-chip microcomputer main control chip is to the interrupt requests response and make respective handling, thereby promptly add up interruption times and realize tally function, according to different count value single-chip microcomputer main control chip output high-low level control light emitting diode (LED1, LED3, LED4) light on and off, opening timer simultaneously interrupts, the pulse that produces different frequency makes buzzer U(BELL) send music, consider the situation that shuttlecock falls on the ground at last, increase falls on the ground measuring ability in the software design, to reach accurate counting.

That main control chip is selected is the low-power scm STC12LE2052 of paster encapsulation, has 20 pins, and low in energy consumption, static current of lcd has only 4-7mA under the normal mode of operation, therefore uses button cell also to have long service life; Its inside has the RC oscillator, need not external crystal oscillator, can save components and parts and PCB space, and two groups of I/O mouths of P1, P3 are arranged, and mainly as data level output, its P3.2 mouth is as interrupting the input port.

Circuits for triggering adopt the P3.2 mouth to link to each other with two touching switches, and when the touching switch was under pressure, circuit was connected, and the INTO of chip is the interrupt signal of response external just.Outside triggering signal as the initial signal of whole system, makes main control chip begin to control that count value increases progressively and count value is presented on the charactron, controls the light on and off and the buzzer U(BELL of light emitting diode (LED1, LED3, LED4) simultaneously) sounding.Acoustic luminous display circuit, in light emitting diode (LED1, LED3, LED4) illuminating circuit, chip P3.0, P3.7 link to each other with LED 1, LED3, LED4 respectively with the P1.0 mouth, when count value changes, chip is exported corresponding high-low level from P3.0, P3.7 and P1.0 mouth, thereby makes the light of light emitting diode (LED1, LED3, the LED4) different colours that glitters.In charactron LED-3WE1 display circuit, adopt Trinitarian small-sized anode charactron altogether to carry out count value, chip selects as the position of charactron from P3.0, P3.5 and P3.3, and P1.1-P1.7 is as Duan Xuan, the logarithmic code pipe carries out gating, so that it shows corresponding count numbers.In buzzer generation circuit, the triode that links to each other with the P.4 pin of chip interrupts producing pulse with timer and makes buzzer send some kinds of different genres of musics as the gating switch of buzzer.

The selection of main components and parts: U adopts the small-sized buzzer of BELL in the accompanying drawing 2; S1, S2 adopt the small, light key switch, and the LR44 type button cell of 1.5V is adopted in the VCC power supply; Triode Q1-Q4 selects 9015 paster models; Resistor R 1-R4 selects 510 Ω paster models.

Though described embodiments of the present invention in conjunction with the accompanying drawings, the protection domain that those of ordinary skills do not need various distortion that creativity work just can make or modification still to belong to this patent within the scope of the appended claims.
