Problem to be solved in the utility model is that existing question-and-answer game apparatus layout comparison is loaded down with trivial details, also more single deficiency of the function realizing.

Question-and-answer game apparatus, comprise singlechip control chip, power circuit, latch cicuit, display circuit, warning circuit, timing circuit, reset circuit, race to be the first to answer a question button and backer's gauge tap, the pin of described singlechip control chip by wire with power circuit, latch cicuit, display circuit, warning circuit, timing circuit, reset circuit, race to be the first to answer a question button and be connected with backer's gauge tap.

Described singlechip control chip model is AT89C51 series.

Described reset circuit is made up of an electrochemical capacitor, resistance, 5V power supply and a button, electrochemical capacitor and button are parallel with one another, one end is linked on the p1.3 pin of singlechip control chip, the other end is connected with 5V power supply, a resistance one end is linked on the p1.3 pin of singlechip control chip, and the other end is connected with 5V power supply.

Described warning circuit amplifies rear drive loudspeaker by singlechip control chip P2.7 mouth signal out by current resistor and triode and forms.

Described display circuit is that 4 LED digital display screens coordinate driving circuit to form.

The utility model has the advantages that: this question-and-answer game apparatus integrates counting, the function such as reports to the police, races to be the first to answer a question, and cost is also lower, simple in structure, is applicable to a lot of medium and small places.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model question-and-answer game apparatus;

In figure: 1, singlechip control chip 2, power circuit 3, latch cicuit 4, display circuit 5, warning circuit 6, timing circuit 7, reset circuit 8, race to be the first to answer a question button 9, backer's gauge tap.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

Question-and-answer game apparatus, comprise singlechip control chip 1, power circuit 2, latch cicuit 3, display circuit 4, warning circuit 5, timing circuit 6, reset circuit 7, race to be the first to answer a question button 8 and backer's gauge tap 9, the pin of described singlechip control chip 1 by wire with power circuit 2, latch cicuit 3, display circuit 4, warning circuit 5, timing circuit 6, reset circuit 7, race to be the first to answer a question button 8 and be connected with backer's gauge tap 9.

Described singlechip control chip 1 model is AT89C51 series, AT89C51 single-chip microcomputer is the high performance CMOS 8-bit microprocessor of a kind of low-voltage, can provide following standard feature: 32 I/O mouth lines, 4k bytes Flash flash memory, two 16 bit timings/counters, 128 byte inner RAM, 5 vectorial two-stage interrupt structures, sheet internal oscillator and clock circuit, a full duplex serial communication port.Meanwhile, AT89C51 can be down to the static logic operation of 0Hz, and supports two kinds of optional power saving operation patterns of software.The work of idle mode: CPU stops, but Timer/Counter, RAM, interrupt system and gang up casually and still can work.Power-down mode: the content in RAM is preserved, and oscillator quits work and forbids other element work until next hardware reset simultaneously.

Described reset circuit 7 is made up of an electrochemical capacitor, resistance, 5V power supply and a button, electrochemical capacitor and button are parallel with one another, one end is linked on the p1.3 pin of singlechip control chip 1, the other end is connected with 5V power supply, a resistance one end is linked on the p1.3 pin of singlechip control chip 1, and the other end is connected with 5V power supply; Reset signal in the time that switching on power, system is provided, until system power supply stable time, is cancelled the reset signal of RST end, and the effect of Here it is reset circuit.After power supply is stable, will just can cancel through certain time delay the reset signal of RST end, while preventing power switch shake, impact resets.

Described warning circuit 5 amplifies rear drive loudspeaker by singlechip control chip 1 P2.7 mouth signal out by current resistor and triode and forms.

Described display circuit 4 is that 4 LED digital display screens coordinate driving circuit to form, and realizes digital demonstration by the programming part of single-chip microcomputer inside.

The circuit of racing to be the first to answer a question button 8 adopts matrix keyboard.Do the determinant keyboard of a 4*4 at the P1 of AT89C51 mouth, comprise " beginning ", " adding one ", " subtracting one " key etc.Make the high electricity of P1.0 to P1.3 output frequently by inside programming, at the low electricity of P1.4 to P1.7 port output frequently.Put on numbering by calculating to each button, in the time having button to press, the electricity of P0 port can change frequently, can show at display unit the person's of racing to be the first to answer a question number by the inside programming of single-chip microcomputer, backer's gauge tap 9 comprises three, race to be the first to answer a question and start button and mainly race to be the first to answer a question and start to control, " adding one " button and " subtracting one " button carry out the adjustment of countdown time.

Warning circuit 5 is mainly used in pointing out the beginning of racing to be the first to answer a question and racing to be the first to answer a question overtime two kinds of situations.Single-chip microcomputer P2.7 mouth signal out amplifies rear drive loudspeaker by current resistor and triode and occurs.Timing circuit 6 is mainly pressed and is started to race to be the first to answer a question laggard the robbing of button and answer countdown host.Latch cicuit 3 adopts priority encoding structure, mainly carries out the coding of key information; Then the key information after coding is stored.

Installation method of the present utility model: after this device energising, display circuit 4 rear two can the Displaying timer time, front two shows 0, illustrates that nobody races to be the first to answer a question, the initial setting time of countdown is 20 seconds.The time that can adjust by the time adjustment key on right side countdown, adjustable extent is 0-99.When we press after " beginning " key, the numeral of demonstration starts countdown, if when counting while making zero nobody press and race to be the first to answer a question button 8, warning circuit 5 can send prompt tone, epicycle is raced to be the first to answer a question end.If before counter makes zero, someone presses and races to be the first to answer a question button 8, and system is understood priority processing validity at first, shows the person's of racing to be the first to answer a question numbering at the front two of display circuit 4.
