Abstract

The invention provides a pressure sensing tug-of-war river channel, which belongs to the technical field of sports equipment and comprises a river channel; set up the sensing region in the river course, sensing region inside is provided with pressure sensor, still set up temperature sensor on the sensing region. According to the method, the pressure sensor and the temperature sensor are used for performing auxiliary monitoring on the tug-of-war competition, so that manual judgment is replaced, and the accuracy and the fairness of the tug-of-war are improved.

Description

Pressure sensing tug-of-war river channel

Technical Field

The invention relates to sports equipment, in particular to a pressure sensing tug-of-war river channel.

Background

The field requirement of the tug-of-war is very simple, and the tug-of-war activity can be carried out only by a flat land with the width of more than 5 meters and the length of about 20 meters. The modern general tug-of-war method is: two parallel straight lines are drawn on the ground to form a river boundary, two teams with the same number of people respectively hold one end of each rope on two sides of the river boundary, and after smelling the instructions, the ropes are pulled forcefully to pull the opposite side out of the river boundary to win the instructions.

In the existing tug-of-war competition, the actions of team members of both sides are judged by the naked eye observation of a judge, however, the artificial judgment has great limitation, and the accurate judgment can not be carried out on whether the body part of the team member with the foot removing accident contacts the ground or not, so that the victory or defeat of the tug-of-war competition is influenced, and the fairness of the tug-of-war competition is influenced.

Disclosure of Invention

Aiming at the defects of the prior art, the invention aims to provide a pressure sensing tug-of-war river channel which can intuitively reflect whether a team member makes an infraction or not.

In order to solve the technical problems, the invention provides the following technical scheme:

a pressure sensing tug-of-war river channel comprises a river channel; a sensing area is arranged in the river channel; a pressure sensor is arranged in the sensing area.

As a further improvement of the invention: the sensing area is also provided with a temperature sensor.

As a still further improvement of the invention: the temperature sensors and the pressure sensors are linearly and alternately distributed in the sensing area.

Compared with the prior art, the invention has the beneficial effects that:

according to the method, the pressure sensor and the temperature sensor are used for performing auxiliary monitoring on the tug-of-war competition, so that manual judgment is replaced, and the accuracy and the fairness of the tug-of-war are improved.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Reference will now be made in detail to embodiments of the present patent, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present patent and are not to be construed as limiting the present patent.

In the description of this patent, it is to be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for the convenience of describing the patent and for the simplicity of description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the patent.

In the description of this patent, it is noted that unless otherwise specifically stated or limited, the terms "mounted," "connected," and "disposed" are to be construed broadly and can include, for example, fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meaning of the above terms in this patent may be understood by those of ordinary skill in the art as appropriate.

Referring to fig. 1, the present embodiment provides a pressure sensing tug-of-war river channel, including a channel 1; a sensing area 2 is arranged in the river channel 1; the pressure sensor 3 is arranged in the sensing area 2, the pressure area above the river channel 1 is detected through the pressure sensor 3, when the pressure area is detected to be larger than the foot area of a human body, the foul is considered, because when the pressure sensor 3 detects that the pressure area is larger than the foot area, the human body is proved to have other parts to touch the ground; the temperature sensor 4 is further arranged on the sensing area 2 and used for detecting the temperature of a human body, and when the pressure sensor 3 is not triggered due to slight contact with the ground at other parts during tug-of-war, judgment errors are caused, the temperature sensor 4 can assist in carrying out foul detection on the athlete, and when the limb of the human body except the foot contacts the ground, the temperature of the human body is detected through the temperature sensor 4 and is used for judging whether the athlete breaks down; the temperature sensor 4 and the pressure sensor 3 are linearly distributed in a staggered manner in the sensing area 2.

The working principle of the invention is as follows: when people perform a tug-of-war competition, the pressure sensor 3 is used for detecting the pressure area above the river channel 1, and when the pressure area is detected to be larger than the foot area of a human body, the pressure sensor 3 is regarded as a foul, because when the pressure area is detected to be larger than the foot area by the pressure sensor 3, the human body is proved to have other parts touching the ground; however, when the pressure sensor 3 cannot be triggered by slight contact with the ground at other parts during tug-of-war, judgment errors occur, the temperature sensor 4 can assist in carrying out foul detection on the athlete, and when the limb of the human body except the foot contacts the ground, the temperature sensor 4 is used for detecting the body temperature of the human body and judging whether the athlete breaks down.

According to the method, the pressure sensor 3 and the temperature sensor 4 are used for performing auxiliary monitoring on the tug-of-war competition, manual judgment is replaced, and the accuracy and the fairness of the tug-of-war competition are improved.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
