Abstract
The invention relates to an automatic monitoring system of fouls in a heel-and-toe walking race, mainly comprising a data input module, a display module, a data acquisition module, a data processing module and a data transmission module, wherein the data input module has a function of inputting number information of sporters into the system; the display module is used for displaying the input numbers of the sporters through a digital tube; the data acquisition module is used for transmitting acquired action data of the sporters to a processor for process; and if the sporters does fouls, the data transmission module is used for transmitting the foul data and the number of the sporters. The automatic monitoring system disclosed by the invention has the advantages of simple structure, convenience for operation, accurate judgment and the like.
Description
Technical field
The present invention relates to a kind of heel-and-toe walking contest unnecessary roughness automatic monitoring system.
Background technology
Footrace is that judge's subjective factor is got involved at most in athletic competition, the most difficult track and field sports project of expecting of result.Say objectively, lean on action that referee's vision differentiates walker moment whether standard be unusual difficulty.The eyes that replace judging with electronic instrument are directions of physical culture development in science and technology, only in this way just real fair competition can be arranged.Filled up this blank based on the design of the footrace training smart judgment system of wireless transmission, it can help the referee that objective, a unified standard is provided.
Heel-and-toe walking contest has two core rules: one of which, the footrace player must remain a pin and drop on the ground.Its two, reach vertical posture from a moment that the pin that advances lands up to shank, shank must keep straight line, knee can not be crooked.
Do not accomplish that above player is regarded as foul at 2, the referee can warn, if a player will be fouled out office by three warnings.
Stipulated in 1996～1997 years and Chinese track and field association notice according to International Track and Field Association's handbook; Since 1996; The footrace definition prevents that by keeping single both feet alternately to support the prescribed specific of soaring from changing " not having visible soaring (observing with eyes) ", exist [1] of having given tacit consent to the phenomenon of soaring in the footrace into.Again according to the achievement in research of " the walking events scientific research of 1992 Olympic Games China ": in the heel-and-toe walking contest less than 42 ms for rationally soaring the time limit; 42 ms～47 ms soar the time limit for fuzzy; Soar the time limit for foul greater than 70 ms.Therefore, the key of native system research is exactly soaring the time limit of capture movement person, and judges, if greater than rationally soaring the time limit, can notify the judge.
Advantages such as that the present invention has is simple in structure, easy to operate, the judge is accurate.
Summary of the invention
The invention reside in provides a kind of heel-and-toe walking contest unnecessary roughness automatic monitoring system.
The technical scheme that adopts:
Heel-and-toe walking contest unnecessary roughness automatic monitoring system mainly comprises data input module, display module, data acquisition module, data processing module and five parts of data transmission module.Wherein, The function of data input module is to be input to athletic number information in the system; Display module then shows the player number of input through charactron; Acquisition module is delivered to the player motion data of gathering in the processor and is handled, if the player motion foul, then will break the rules data and racing number of transmitter module sends.
Systemic-function
Heel-and-toe walking contest has two core rules: one of which, the footrace player must remain a pin and drop on the ground.Its two, reach vertical posture from a moment that the pin that advances lands up to shank, shank must keep straight line, knee can not be crooked.Do not accomplish that above player is regarded as foul at 2, the referee can warn, if a player will be fouled out office by three warnings.
Stipulated in 1996～1997 years and Chinese track and field association notice according to International Track and Field Association's handbook; Since 1996; The footrace definition prevents that by keeping single both feet alternately to support the prescribed specific of soaring from changing " not having visible soaring (observing with eyes) " into, given tacit consent to the existence of the phenomenon of soaring in the footrace.Again according to the achievement in research of " the walking events scientific research of 1992 Olympic Games China ": in the heel-and-toe walking contest less than 42 ms for rationally soaring the time limit; 42 ms～47 ms soar the time limit for fuzzy; Soar the time limit for foul greater than 70 ms.Therefore, the key of native system research is exactly soaring the time limit of capture movement person, and judges, if greater than rationally soaring the time limit, can notify the judge.
Therefore, if sportsman's double float time limit greater than 70 ms promptly through two sole sensor acquisition to signal time limit difference judge then that greater than 70 ms the sportsman breaks the rules, if less than 70 ms then in normal range (NR).
Each device effect and signal type
The design is based on the footrace intelligent decision of AT89C51 single-chip microcomputer, mainly comprises: 7 parts such as data input module, display module, data acquisition module, data processing module and data transmission module, clock circuit module and system's reseting module.
Data input module: form by 4 * 4 keyboards, athletic identity number information is input in the system, to be used for information such as sportsman's identification and track record through this keyboard.
Display module: form by 2 LED charactrons, can the athletic number information by the keyboard input be shown through it.
Data acquisition module: form by acceleration vibrating sensor and analog-to-digital conversion module.The acceleration vibrating sensor that is installed in sportsman's sole is used for measuring the athletic action messages such as pin motion of lifting; Sensor is sent to the analog signal of measuring in the analog-to-digital conversion module; Is data signal by analog-to-digital conversion module with the analog signal conversion of importing, and this data signal is input in the processor handles then.Analog-to-digital conversion module is made up of a slice modulus conversion chip ADC0809, a slice 74LS373 chip, two 7474 chips, a slice 74LS02 chip, not gates.Wherein AD0809 is a data signal with analog signal conversion, and the 74LS373 chip is used for data and latchs, and D flip-flop 7474 chips that triggered by two two rising edges are used for to ADC0809 external clock signal frequency split.
Processor: constitute by a slice AT89C51 single-chip microcomputer.This module is used for Information Monitoring is handled, and judges according to image data whether duration of passage surpasses 70ms, if send above foul information is delivered to transmitter module.
Transmitter module: form by phaselocked loop 4046, resistance capacitance, triode and chip CA2810C.Phaselocked loop 4046 pins phase of input signals, makes frequency comparatively stable, and chip CA2810C is a broad band amplifier, is used for radiofrequency signal and amplifies.The signal cover that transmitter module is set is 500 meters; When sportsman's foul reaches certain number of times; Information such as sportsman's identity numbering, foul times, foul time are launched through transmitter module, and the system that in signal cover, accepts is with in timely this information storage system.
System's reseting module: this module is made up of resistance R 1, capacitor C 1, is used for system and resets.
The clock circuit module: being made up of capacitor C 2, C3 and crystal oscillator, is the dynamical system of whole system, for system provides clock signal.
The specific embodiment
At first the sportsman is input to athletic number in the system through 4 * 4 keyboards; And demonstrate athletic number through the LED charactron; Data acquisition module is gathered athletic double-legged exercise information in real time in the middle of the match; And in processor, handle, after sportsman's foul, system will pass athletic number and foul record through transmitter module.
