Description

Auxiliary tester for football positioning ball passing

technical field

The invention relates to a sports equipment, in particular to an auxiliary tester for passing a football positioning ball.

Background technique

Accurate set ball passing is one of the main items in the training and evaluation of football players' special skills. At present, the training and testing grounds for football positioning ball passing technology usually draw three concentric circles with a radius of 2 meters, 3 meters and 4 meters on the football field. With a radius of 25 meters (boys) and 20 meters (girls) as the radius, draw a 5-meter-long arc from the center to any direction as the pass limit line; the evaluation method for positioning the ball is: Candidates place the ball on the limit line When passing the ball into the circle with either foot, it is valid if the ball lands in or on the circle. Each kick that hits a circle with a radius of 2 meters gets 6 points, each kick that hits a circle with a radius of 3 meters gets 4 points, each kick that hits a circle with a radius of 4 meters gets 2 points, and those who don’t hit a circle get no points. There are some deficiencies as follows when adopting the above-mentioned method of inserting small flags and drawing the field to carry out the accurate technical training and evaluation of football positioning ball passing: 1. The circle lines on the field are generally marked by sprinkling white ash on the field, and after being stepped on for many times Or the circle line will become blurred after being blown by the wind, which will affect the examiner's judgment. 2. Every time a candidate takes a test, the examiner must visually measure the score near the circle. Standing near the circle will affect the candidate's aiming, and the examiner is also very hard. 3. Candidates' grades are determined by the examiner's visual inspection, which is too subjective and easy to cheat. 4. The small flag in the center of the bull's eye will affect the landing point of the football. If the football just hits the flag, it will directly affect the test taker's score.

In view of the above problems, some solutions have been disclosed in the prior art, such as the patent number: 201420021747.0, and the patent name is: the Chinese invention patent of football positioning ball pass accurate mark circle discloses a kind of: a kind of football set ball pass accurate mark circle , the main structure of the sign circle is composed of outer wall, universal casters, upper bracket, lower bracket, central pier, sign pole, sign ball and circle net; among them, the lower end of the outer wall is connected with six upper supports and six One end of the lower bracket is fixedly connected, the other ends of the six upper brackets are respectively fixedly connected to the upper end of the central pier, the other ends of the six lower brackets are respectively fixedly connected to the lower end of the central pier, the upper end of the central pier is fixedly connected to the lower end of the sign pole, and the upper end of the sign pole It is fixedly connected with the lower end of the sign ball. The outer wall, the six upper brackets and the central pier are respectively provided with hooks, and the hooks are connected with ring nets. The ring nets are composed of inner ring nets, middle ring nets and outer ring nets of different colors The outer wall is composed of several universal casters with fixed valves at the lower end of the outer ring wall. The soccer set ball of above-mentioned structure passes the quasi-sign circle and just has solved the problem of marking line, promptly the first problem in the weak point mentioned above. But when it is still practical, there are still three deficiencies mentioned in 2, 3, and 4 in the above-mentioned problem.

To sum up, in the prior art, there is a lack of an auxiliary tester for soccer positioning ball passing that has clear boundaries, is not easy to be worn out, does not require visual inspection by examiners, and automatically inputs scores into computers.

Contents of the invention

The technical problem to be solved by the present invention is to provide an auxiliary tester for football positioning ball passing with clear boundaries that are not easy to be worn out, no need for visual inspection by examiners, automatic input of scores into computers, little influence of bullseye marks on scores, and effective prevention of cheating.

In order to solve the above-mentioned technical problems, the technical solution provided by the present invention is: an auxiliary tester for passing a football set ball, which includes a carpet with a pressure sensor array, and the pressure sensor array on the carpet covers a range of one A circle with a radius of four meters; there are also two-meter boundary marking lines, three-meter boundary marking lines and four-meter boundary marking lines on the carpet. The three marking lines are concentric circle structures, and the center of the concentric circles is Bull's-eye area, the bull's-eye mark that will not affect the landing point of the football is provided at the bull's-eye area; the area circled by the four-meter boundary line coincides with the area covered by the pressure sensor array; the pressure sensor on the carpet A wireless communication module is electrically connected; the wireless communication module is connected to a computer through a wireless signal.

Preferably, the carpet is a whole circular structure with a radius of four meters, and the pressure sensor array is arranged in the interlayer of the carpet.

As a preference, the carpet is a split circular structure with a radius of four meters spliced by multiple sub-carpets, and each sub-carpet is provided with a pressure sensor array; and all the pressure sensor arrays are connected to the computer signal .

Preferably, the bull's-eye mark includes a flag and a telescopic mechanism; the flag is installed on the telescopic mechanism; the telescopic mechanism is buried under the bull's-eye area, and the telescopic mechanism is remotely controlled by a computer or equipped with An independent remote control switch; the telescopic mechanism is used to drive the flag to extend above the bull's-eye area or retract below the bull's-eye area; the bull's-eye area is provided with a through hole for the flag to pass through.

As a further preference, said flag-inserting includes a flagpole, an inner pole and a longitudinal row of teeth; said telescopic mechanism includes a drive motor and a drive gear; said flagpole is slidably sleeved on the inner pole, and There is a longitudinal row of teeth; the drive gear meshes with the longitudinal row of teeth; the drive gear is driven by a drive motor; the drive motor is remotely controlled by a computer or equipped with an independent remote control switch.

Preferably, the bull's-eye mark includes a light source; the light source is buried under the bull's-eye area, and the light source is remotely controlled by a computer or equipped with an independent remote control switch; the bull's-eye area is a grid structure, and the bull's-eye Except for the pressure sensor array, the others are transparent structures or hollow structures; when the light source is turned on, a beam of light will be emitted vertically upward from the bullseye area.

As an improvement, it also includes a sensor for monitoring wind force and wind direction on site, and the sensor is connected with the computer signal.

As an improvement, it also includes a sensor for monitoring the temperature and light intensity on site, and the sensor is connected with the computer signal.

As an improvement, it also includes a high-speed camera for recording the candidate's kicking action and football flight trajectory, and the high-speed camera is connected with a computer signal.

After adopting the above structure, the present invention has the following beneficial effects: the range covered by the pressure sensor array on the carpet is a circle with a radius of four meters. That is to say, there are sensors in the area where the score can be generated in the test. As long as the football falls on the scoring area, the sensor can quickly and accurately detect the position of the football and send it to the computer. The examiner only needs to compare the pictures on the computer to get the candidate's score. The data is transmitted through wireless transmission. The examiner can sit in the stand to invigilate the test instead of squatting near the scoring circle for real-time observation. This innovation has brought multiple benefits: the first is to eliminate the influence of the examiner on the candidate's aiming at the target, because if the examiner stands near the target, it is easy for the candidate to be distracted and unable to concentrate on aiming at the target. Second, it is easier for the examiners themselves, because they can see the results in real time while sitting in the stands. Third, the scores recorded by sensors are more accurate, which can effectively prevent misjudgments and cheating.

The second major innovation of this patent application is that this patent application uses a bullseye mark that will not affect the landing point of the football. The bullseye mark is used to allow candidates to locate the bullseye, which is essential, otherwise they would stand at 20 It is difficult for candidates who are many meters away to aim at the bull's-eye mark, but the flaw of the traditional fixed mark is that when the football touches it, it will affect the landing point of the football, resulting in inaccurate results. Neither the retractable flag-inserting scheme nor the light column scheme adopted in this patent application will affect the landing point of the football. Taking the telescopic flag-inserting scheme as an example, when the examinee is aiming, the examiner remotely controls the telescopic mechanism through a computer or a switch The flag sticks out above the bull's-eye area. After the candidates finish kicking the ball, the examiner immediately controls the retractable mechanism through a computer or a switch to retract the flag to below the bull's-eye area. When the football falls, it will not be affected by the flag. At the same time, the sensor array on the bull's-eye area can still detect where the football falls on the bull's-eye. The beam of light scheme is more convenient. The light is shot from the bottom of the target area, even if the football hits the beam of light, it will not affect the landing point of the football. In addition, the marking line is set directly on the carpet, which can be printed or sewn in two ways, which is more wear-resistant than sprinkling ash on the ground.

In addition, as an optimization and improvement, wind force and direction sensors, temperature and light intensity sensors can also be added, and equipment such as high-speed cameras used to record candidates' kicking movements and football flight trajectories can be recorded more scientifically and objectively. The environment and the whole process of the test taker can be used for subsequent result analysis, action correction, etc. At the same time, one person can also create a file, real-time imaging and archiving of photos and scores when playing football, which can prevent others from cheating in the test .

Regarding the bull's-eye mark that will not affect the landing point of the football, there are also multiple implementations as follows. In the first one, the bull's-eye mark includes a drone and a flag. After the ball is played, the drone can fly directly away from the score recording area with the flag. In the second type, the bull’s-eye mark includes a blowing pipe and a streamer, the blowing pipe is connected with a blowing pump, the blowing pipe is a hose, and is arranged above the bull’s-eye area, and a vertical Upward soft joint, there are many ribbons connected to the flexible joint, the ribbons are blown up by blowing air for identification, and the examinee stops blowing after kicking the ball. It will affect the landing point of the football. When the football falls on the blowing pipe or streamer, it will still trigger the pressure sensor below to record data. The third type is the side-down flagpole structure, that is, a micro motor is connected under the flagpole, and the motor can rotate reciprocally within 90 degrees. When the examinee kicks the ball, the motor drives the flagpole to fall down and directly falls on the carpet. , when the football falls on the flag or the flagpole, the pressure generated can still be recorded by the pressure sensor. In addition to the above three schemes, other similar schemes can also be adopted. The above three schemes also have an advantage in that they do not need to dig holes on the football field. Can be applied to set the examination room directly on the football. And the two schemes in the embodiment one and two of the present application need to dig holes on the examination room to install the equipment, which is suitable for a special examination room. Of course, it is also possible to use it on a conventional football field, but after using it , just fill the hole.

With regard to the description of the pressure sensor array, there are many mature products in the prior art that can perform large-area pressure testing and automatically generate pressure graphics. In this patent application, it is preferable to use a flexible array pressure sensor. The flexible array pressure sensor is a mature pressure sensor, which can be pressed and bent arbitrarily like a piece of paper. The specific structure of the sensor is composed of upper and lower layers of polyester film. Several conductors are distributed in the middle of the two layers of film along the horizontal and vertical directions. The intersection point of the two conductors in different directions is equipped with a sensor unit. When the two films are combined under force, an array of pressure-sensing points will be generated, so that the size of the force-bearing area of the force-bearing place can be described. The specific sensor products include the standard Tekscan pressure sensor developed by Tekscan Company. If the Tekscan pressure sensor is used, it is equipped with analysis software, which can obtain a two-dimensional map of the football landing point in real time. Regarding the wireless connection between the wireless communication module 5 and the computer 6, there is already a very mature prior art, and no detailed description will be given here.

Further combined with Figure 5, when the football kicked by the examinee falls into the scoring area, a drop point map as shown in the figure will be generated. After obtaining this map, the examiner can manually score according to this map, or it can be scored by a computer. For further automatic scoring, the scoring rules can be carried out according to the following rules: each kick that hits a circle with a radius of 2 meters gets 6 points, including the circle line itself; every kick that hits a circle with a radius of 3 meters gets 4 points, including the circle line itself; Those who kick the circle with a radius of 4 meters will get 2 points, including the circle line itself; those who do not hit the scoring area will not get any points. Judgment about the pressure line can be judged according to the position of the center point of the landing mark; according to the following rules, the center point 12 of the ball mark 11 corresponding to the mark in Figure 5 is located inside a circle with a radius of 3 meters, so 4 points But if the center point 12 of the ball mark is located in the 4-meter circle outside the 3-meter circle, even if the ball mark 11 is pressed on the line, only 2 points will be scored. It can also be judged according to the position where the mark of the landing point is touched as a whole, and the side with the largest score is used for judgment. Similarly, the score corresponding to the mark in Figure 5 is 4 points.

Regarding the description of the software part involved in this patent application, since the computer is used in this patent application, it will inevitably involve the software part that ensures the operation of the computer, but the focus of this patent application is not on the software, the software part is the hardware that comes with it. Yes, for some recording and analysis functions involved in this patent application, even if there are no ready-made programs available, technical personnel in the industry can also write corresponding processing programs, but these are all existing technologies, and ordinary software programmers can use them according to It is hereby explained that there is no need to pay creative labor to compile the corresponding processing procedures according to the requirements of the product.

The present invention and its implementations have been described above, and the description is not limiting. What is shown in the drawings is only one of the implementations of the present invention, and the actual structure is not limited thereto. All in all, if a person of ordinary skill in the art is inspired by it, and without departing from the inventive concept of the present invention, without creatively designing a structure and an embodiment similar to the technical solution, it shall fall within the scope of protection of the present invention.
