Abstract
Detection circuit by infrared transmitting circuit, receives sounding modular circuit and counts display module circuit composition in violation of rules and regulations for footrace based on 555 timers.Detection circuit can be detected effectively for foul of being lifted during footrace in violation of rules and regulations for footrace based on 555 timers, if sportsman it is double-legged and meanwhile it is liftoff foul infrared detector if can detect, unison counter counts once, and buzzer also sends auditory tone cues sportsman foul.The circuit can reduce the behavior of coach's erroneous judgement to a certain extent, and either footrace team member is still trained and all provides certain foundation.
Description
Art
The present invention relates to the footrace based on 555 timers to detect circuit in violation of rules and regulations.
Background technology
Footrace is China's one of track and field event with very strong competitiveness in the world match.Race walking is from generation and sends out
Since exhibition, the hard-working paid along with the coach, sportsman and scientific research personnel of countries in the world and study assiduously, in rule
It is rigorous, penalty it is just, technology it is reasonable, identification fine aspect, a step by a step towards more science, more smart sharp side
To vigorous growth.Commonly walk it is identical with the movement structure of footrace, be all by single pin support and both feet support alternate repetition carry out.
But footrace has its feature, Anterior and posterior ring of pelvics rotates greatly, and waist has certain twisting, and two arm swings, leg fully stretches when pin contacts to earth
Stride is big, and frequency is high, and pace is fast.Footrace has two core rules：One walker must remain at least
One pin contacts with ground；Until leg reaches vertical posture from a moment of advance pin landing, leg must keep straight line,
Knee can not be bent.
Team member has foul suspicion to be warned in hands-on, match, and foundation of without nothing reliable, sportsman is such as
Fruit meets that footrace defines, and has foul suspicion, is just alerted and is fouled off by judge, so sometimes will be unjust to some sportsmen
It is flat.
The content of the invention
To solve the above problems, the present invention devises the detection circuit in violation of rules and regulations of the footrace based on 555 timers.
The technical solution adopted for the present invention to solve the technical problems is：
Detection circuit by infrared transmitting circuit, receives sounding modular circuit and counting is shown in violation of rules and regulations for footrace based on 555 timers
Module
Circuit forms.
The infrared transmitting circuit, infrarede emitting diode in circuit, using arsenic potassium infrarede emitting diode
LD274, it belongs to optic angle light emitting diode, and optic angle refers to the transmitting cone of its die making（Parabola）Angle it is larger, angle
Degree is less than 160o.Its blanking voltage is 4V, and the dash current allowed in conducting electric current 30mA, t=10us is 2.5A, loss
210uw, loss are minimum.
The reception sounding modular circuit, infrared receiver component use a kind of inner existing frequently-used integrated infrared receiving terminal
（JST）To receive the infrared signal that infrared transmission module is launched, integrated infrared receiving terminal（JST）Should in TV remote controller
With the circuits such as preposition amplification, limited range enlargement, detection, voltage stabilizing most extensively, are built-in with, the signal of infrared circuit transmission, pass through（JST）Place
After reason, output pulse signal, then the control through R2, VD1, by the modulation of 555 time base circuits, finally by the 3 of 555 time base circuits
The pulse signal of pin output amplification exports in CP after operational amplifier VT2 amplifications and sound is sent on buzzer.
The counting display module circuit, the circuit is using display module CL002 (inside is without counter) and synchronous plus meter
Number device CC4518 compositions, CC4518 are connected into 3 Bits Serial binary-coded decimal counters, and decade counter is carried out under pulse signal CP effects.
The invention has the advantages that detection circuit can effectively be directed to footrace to the footrace based on 555 timers in violation of rules and regulations
Foul of being lifted in journey is detected, if sportsman it is double-legged and meanwhile it is liftoff foul infrared detector if can detect, together
Hour counter counts once, and buzzer also sends auditory tone cues sportsman foul.The circuit can reduce coach to a certain extent and miss
The behavior sentenced, either footrace team member is still trained certain foundation is all provided.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is infrared transmitter figure.
Fig. 2 is infrared receiver and detector circuit figure.
Fig. 3 is decade counter display circuit figure.
Embodiment
In Fig. 1, infrared ray belongs to black light, different with general luminous ray, and its electromagnetic wavelength is in 950nm
In the range of, it is widely used on remote control and transmission equipment.Infrarede emitting diode in circuit, using arsenic potassium infraluminescence
Diode LD274, it belongs to optic angle light emitting diode, and optic angle refers to the transmitting cone of its die making（Parabola）Angle compared with
Greatly, angle is less than 160o.Its blanking voltage is 4V, and the dash current allowed in conducting electric current 30mA, t=10us is 2.5A, damage
210uw is consumed, loss is minimum.Because during footrace, bipod can not be simultaneously liftoff, and what is mainly distinguished is sole, so transmitting
The shift knob of circuit is mounted in heelpiece part, and the other parts of radiating circuit are arranged on vamp, are pressed when switch DR, electricity
Container C1 and 555 time base circuits composition oscillating circuit, its peak point current is up to 1A, and the duration is up to 0.1s.This electricity
Road time delay only has 0.5ms, that is to say, that in violation of rules and regulations whether the circuit have time enough to judge team member.
In fig. 2, the infrared remote receiver of use has very high receiving sensitivity, and its receiving infrared-ray wavelength is closely
900nm, more than the pyroelectric infrared wavelength of human body.Infrared receiver component a kind of existing frequently-used integrated infrared is connect using inner
Receive head（JST）To receive the infrared signal that infrared transmission module is launched, integrated infrared receiving terminal（JST）In TV remote controller
In it is most widely used, be built-in with the circuits such as preposition amplification, limited range enlargement, detection, voltage stabilizing, the signal of infrared circuit transmission, warp
（JST）After processing, output pulse signal, then the control through R2, VD1, by the modulation of 555 time base circuits, finally by base when 555
The pulse signal of the 3 pin output amplification of circuit exports in CP after operational amplifier VT2 amplifications and sound is sent on buzzer
Sound.
In figure 3, the circuit is using display module CL002 (inside is without counter) and synchronous counter CC4518 groups
Into CC4518 is connected into 3 Bits Serial binary-coded decimal counters, and decade counter is carried out under pulse signal CP effects.
