Abstract

This invention relates to one time lag order gun device for sport race, which comprises dial switch unit, trigger unit connected and the sound and light units and time lag units set between dial switch unit and trigger unit, wherein, the dial switch unit output end connects the said time lag unit input end; when in use, pulling dial switch the control signals through fix time lag to trigger sound and light unit and to send sound and light signals.

Description

The time-delay starting pistol device that is used for athletic competition

Technical field

The present invention relates to the athletic competition articles for use, especially relate to a kind of electronic technology that is used for the time-delay starting pistol device of matches such as sports track and field, swimming.

Background technology

At present in athletic competition, particularly in the track and field of using starting pistol, swimming waits in the match, the sportsman robs the situation of setting out and happens occasionally, one of them major reason is to estimate inaccurate blanking time the referee is rung from " preparation " to starting pistol, and this blanking time is by the artificial control of referee, though the athletic competition rule predetermining blanking time, but because the difference of the artificial control of each referee, its difference still has a few tenths of second, even more than one second, and the difference between present athletic competition timing and each the contest ranking has been accurate to a few percent second, even in the centisecond, had influence on accurately athletic the blanking time the sound from " preparation " to starting pistol that is to say artificial control, the ranking of contest, the sportsman of the blanking time of issuing an order of being familiar with chief referee person can be taken the preemptive opportunities, and this has just influenced the fairness doctrine of athletic competition.

Summary of the invention

At the defective that exists in the above-mentioned prior art, technical problem to be solved by this invention provides a kind of time-delay starting pistol device that is used for athletic competition that can accurately control the blanking time the sound from " preparation " to starting pistol.

In order to solve the problems of the technologies described above, a kind of time-delay starting pistol device that is used for athletic competition provided by the invention, comprise: the trigger element and the sounding that is connected described trigger element, luminescence unit of trigger unit, the described trigger of connection unit, it is characterized in that, also comprise the delay unit that is connected between described trigger unit and the described trigger element, be the input that the output of described trigger unit connects described delay unit, the output of described delay unit connects the input of described trigger element; During use, press trigger, control signal could trigger sounding, luminescence unit through the time-delay of fixing (accurately), sends sound, light that contest the sets out signal of issuing an order.

Preferably, the described delay unit that can send delay pulse signal comprises monostable pierce circuit and NAND gate circuit.

The time-delay starting pistol device that is used for athletic competition provided by the invention, owing to adopted accurate (electronics) time-delay mechanism, the control of the blanking time the sound from " preparation " to starting pistol was accurate to below ten thousand/second, so that can ignore, overcome the difference of the blanking time that human factor caused, in matches such as track and field, swimming, demonstrated fully the fairness doctrine of athletic competition.

Description of drawings

Fig. 1 is the theory diagram of the time-delay starting pistol device of one embodiment of the invention;

Fig. 2 is the circuit diagram of the delay unit of one embodiment of the invention time-delay starting pistol device.

The specific embodiment

Below in conjunction with description of drawings embodiments of the invention are described in further detail, but present embodiment is not limited to the present invention, every employing analog structure of the present invention and similar variation thereof all should be listed protection scope of the present invention in.

As shown in Figure 1 and Figure 2, the time-delay starting pistol device that is used for athletic competition in the embodiment of the invention, comprise: the trigger element and the sounding that is connected described trigger element, luminescence unit of trigger unit, the described trigger of connection unit, it is characterized in that, also comprise the delay unit that is connected between described trigger unit and the described trigger element, be the input Vin that the output of described trigger unit connects described delay unit, the output end vo n of described delay unit connects the input of described trigger element; During use, press the trigger K of trigger unit, control signal is passed through the time-delay of the delay unit of being made up of monostable pierce circuit and NAND gate circuit, by the output end vo n of described delay unit triggering through described trigger element, sound, the light that makes sounding, luminescence unit send contest the to set out signal of issuing an order.

As shown in Figure 2, during use, press the trigger K of trigger unit, produce high level signal through the anti-phase of delay circuit 10 and time-delay, the rising edge that produces undersuing makes rising edge circuits for triggering 20 produce start pulse signal, by the output end vo n output of described delay unit.

In the circuit of Fig. 2 embodiment, what delay circuit 10 served as reasons that time-delay 555 time-base integrated circuit IC1 form triggers the monostable oscillator that is output as negative pulse by the pulse signal rising edge, the undersuing process T of triggering back generation finishes blanking time, and then generation rising edge signal triggering rising edge circuits for triggering 20, T=1.1RC wherein, RC is respectively timing resistor R and the timing capacitor C in the delay circuit 10; Rising edge circuits for triggering 20 are served as reasons to go up and are triggered the monostable oscillator by the triggering of pulse signal rising edge that 555 time-base integrated circuit IC2 form, because it is output as negative pulse, the above output pin that triggers 555 time-base integrated circuit IC2 3. connect the input of inverter ic 3, what exported by the output end vo n of described delay unit through inverter ic 3 anti-phase backs is positive pulse signal; In the present embodiment, C1=C3=1000P, C2=C5=0.01 μ, R1=R2=2K, R3=1M, C4=1 μ; The model of 555 time-base integrated circuit IC1, IC2 all is NE555, also can be with other 555 time-base integrated circuit; In an embodiment of the present invention, trigger element can be a relay, also can be solid-state electronic relay, bidirectional analog switch integrated circuit and IGCT; Sounding, luminescence unit can be special-purpose audio ics, also can be accumulation of energy electrion, flasher circuit etc.

Because trigger, monostable pierce circuit, trigger element and sounding, luminescence unit in the embodiments of the invention all are prior aries, those skilled in the art also can design many distortion, and this specification has not just been enumerated one by one.

Claims

1, a kind of time-delay starting pistol device that is used for athletic competition, comprise: the trigger element and the sounding that is connected described trigger element, luminescence unit of trigger unit, the described trigger of connection unit, it is characterized in that, also comprise delay unit, the output of described trigger unit connects the input of described delay unit, and the output of described delay unit connects the input of described trigger element; During use, press trigger, control signal triggers sounding, luminescence unit through time-delay, sends sound, light that contest the sets out signal of issuing an order.
