The utility model can automatically judge long jump pedal fouls, which has high accuracy and is not easy to misjudgment; moreover, it is more intuitive, and allows athletes to "convince" their own pedal foul behaviors through the playback and capture functions.

Description

Long jump pedal foul automatic judgment system

technical field

The invention relates to the field of sports, in particular to an automatic judging system, in particular to an automatic judging system for long jump pedal fouls.

Background technique

Long jump is one of the oldest competitive events, and there is long jump in the "pentathlon" of the Olympic Games in ancient Greece. Long jump is also called rapid long jump. It consists of actions such as run-up, take-off, vacating and landing. Athletes run up in a straight line, take off with one foot behind the front line of the springboard, go through the air stage, and then land with both feet in the bunker. During the competition, the ranking is determined by the distance of the jump. The modern long jump began at the end of the 19th century. It was listed as an official event in the first Olympic Games in 1896, and women's events were added to the fourteenth Olympic Games in 1948. The run-up is an accelerated run with a certain distance and a certain number of steps, which can enable the human body to obtain the maximum horizontal speed and prepare for take-off. Take-off is a process in which the body quickly rises into the air at an appropriate angle after the run-up.

During long jump competitions or training, it is very important to identify fouls by long jumpers stepping on the line. However, the existing technology has the following disadvantages: (1) it mainly relies on visual inspection, which has poor accuracy and strong subjectivity; (2) the switch connects the circuit and infrared rays The method of detecting pedal fouls has a complex structure and high cost, and is not suitable for popularization and application; (3) the method of detecting pedal fouls with rubber balls and plasticine display boards is prone to errors, and will increase the workload of referees; (4) ) The above-mentioned several prior art ways all can not intuitively allow the athlete to " convincingly " to the behavior of own pedal foul.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the poor accuracy, strong subjectivity, complex structure and high cost of the existing long jump pedal foul judgment system, which will increase the workload of referees and cannot intuitively allow athletes to foul their own pedals It provides a more powerful, more flexible, and more intuitive automatic judging system for long jump pedal fouls, and provides convenience for users to the greatest extent.

The technical solution adopted by the present invention to solve its technical problems is:

An automatic judging system for a long jump pedal foul, comprising a pedal and an automatic judging device, the pedal includes a foul line, the automatic judging device includes a microprocessor, a memory, a high-speed camera, an operation panel, an indicator light, a display screen and a power supply, and the micro The processor is respectively connected to the memory, the high-speed camera, the operation panel, the indicator light and the display screen, and the power supply is respectively connected to the microprocessor, the memory, the high-speed camera, the operation panel, the indicator light and the display screen.

As a further improvement, the shooting direction of the high-speed camera is aligned with the foul line on the pedal.

As a further improvement, the automatic determination device further includes a speaker connected to the microprocessor and the power supply.

As a further improvement, the automatic determination device further includes an adjustable bracket for fixing.

As a further improvement, the automatic determination device further includes a power cord for connecting to a fixed power source.

As a further improvement of the above-mentioned embodiment of the present invention, the power source includes a solar cell module.

As a further improvement, the indicator light includes a green LED light and a red LED light.

As a further improvement, the operation panel includes a foul playback button.

The beneficial effects of the present invention are:

(1) The machine automatically determines the foul on the long jump pedal, with high accuracy and no misjudgment;

(2) It is more intuitive, allowing athletes to "convince" their pedal fouls through the playback and capture functions;

(3) Adopt solar power supply method, which is more energy-saving.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

This long jump pedal foul automatic judging system comprises a pedal and an automatic judging device, the pedal includes a foul line, and the automatic judging device includes a microprocessor, a memory, a high-speed camera, an operation panel, an indicator light, a display screen and a power supply, and the microprocessor The devices are respectively connected to the memory, high-speed camera, operation panel, indicator light and display screen, and the power supply supplies power to each module.

The shooting direction of the high-speed camera is aligned with the foul line on the pedal. During the period of time when the athlete is close to the foul line, the high-speed camera shoots the athlete’s motion video, which is processed by the microprocessor to determine whether there is a foul. Further, in case of a foul, send Alarm, the alarm methods include speaker alarm and red LED light alarm, in the case of no violation, the green indicator light is on and the red light is off.

The automatic judging device also includes an adjustable bracket for fixing, the automatic judging device is fixed on the adjusting bracket, the direction can be adjusted according to needs, and the use is convenient and flexible.

There is a foul playback button on the operation panel, which is used to call up the video when the athlete touches the foul line to enhance the persuasiveness of the decision.

The device of the present invention adopts AC power supply, and the power module also includes a solar battery panel, which is switched to a solar power supply mode under sunlight.

The specific embodiments described above have further described the purpose, technical solutions and beneficial effects of the present invention in detail.
