Description

  The present invention relates to land sprint running time measurement.

  A system for measuring the passage time using a phototube as shown in FIG. 12 has been devised as a passage time measurement for sprinting on land.

  When trying to automatically measure the passing time of land sprints, carry the phototube transmitter, phototube receiver and related measuring equipment for the number of passtime measurements to the land track, and then connect the phototube transmitter and phototube receiver to a tripod etc. It is necessary to install them on the left and right sides of the track and connect related measuring instruments between each device. Since the volume and weight of the entire apparatus are bulky and time is required for the preparation work, it is difficult to automatically measure the passing time when practicing with a small number of people of 1 to 2 people.

  Also, in the conventional system, when a tripod with a phototube is installed on the side of the runway, the runway with the tripod cannot be used for practice, or a sprinting runner accidentally touches the tripod with the phototube attached. If you do, there is a risk of injury.

  Therefore, the present invention can be easily carried, installed and operated by one person, has a measurement accuracy that can be used to evaluate time during practice, and is a short-distance run for practice that does not interfere with other practitioners. It is an object to provide a transit time measurement system.

In order to achieve the above object, the invention of claim 1 of the present invention is a transit time measuring system for a short distance on land composed of a detection device and a control device.

The detection device is used by being placed on a line that divides the short-distance track on the right and left just before the practice, just like the marker used during the practice on the ground. It consists of a cover, a condensing lens, a pyroelectric sensor, a wireless transmitter / receiver, and a controller. The cover is made of resin and has high portability, safety, and a mark function similar to those of markers used during land practice. It has a shape limited to within 30 cm. In addition, there is a timing start means by a command from the control device, means for detecting that the runner running on the right and left lanes of the line has passed, measuring and storing the passing time, and means for transmitting the time to the control device .

  The control device includes start sound generation means for the runner, instruction means for starting timing to the detection device, passage time acquisition means from the detection device, and time display means.

  In the invention of claim 2, the cover of claim 1 has a shape similar to that of a marker cone generally used as a distance marker for athletics, and is formed by cutting a cone or the top of the cone parallel to the bottom surface. The material is a resin.

  Or as invention of Claim 3, the cover of Claim 1 is the shape of the range of width 5-30cm seeing from a starting point direction, depth 5-30cm, height 3-30cm, and a material is resin. .

  According to a fourth aspect of the present invention, the control device according to the first, second, or third aspect comprises a wireless transmission / reception unit, a control unit, a sound generation unit, and a display unit.

And a start sound generation means for the runner and a command means for starting timing to the detection device, and the display operation control device includes a wireless transmission / reception unit, a control unit, and a display unit. Passage time obtaining means and time display means.

  The effect of claim 1 of the present invention is that a pyroelectric sensor and a condensing lens are arranged at two positions on the left and right sides of a resin cover, and a detection device equipped with a wireless transceiver and a control unit is placed on the line between the runways. By using it, it becomes a lightweight and compact measuring system that does not use a tripod or the like, and is easy to carry and easy to install.

  Moreover, since the pyroelectric sensor and the condensing lens are attached to the cover in two directions on the left and right sides so as to detect the runner's body, the runner 2 that passes the right side of the detection device and the runner 2 that passes the left side of the detection device. It can measure a person's time at once, and can practice a dash practice in a competitive format that is closer to the game.

  Furthermore, since the control device has a start sound generation means for the runner and a command means for starting timing to the detection device, by operating the control device, guidance processing until the start is performed by voice. You can focus your mind on the start dash. Moreover, the time data stored in the plurality of detection devices can be displayed at a time by having the passage time acquisition means and the time display means.

  The effect of claim 2 is that the detection device can be installed on the line that divides the runway, and the height at the time of installation can be kept low by using a resin marker cone-shaped cover that is used as a distance indicator for athletics. Therefore, it does not get in the way of other practitioners, and the resin cover itself has the effect of calling attention to other practitioners. The cover made of metal can be crushed, preventing injury to other trainees.

  The effect of claim 3 is that it is possible to optimize the shape of the detection device so as to have a mark function, a detection function, and a function that does not interfere with other practitioners, without being limited by the conventional marker cone shape.

  The effect of claim 4 is that the control device is composed of a wireless transmission / reception unit, a control unit, a sound generation unit, and a display unit, so that the runner himself can perform a start operation and check time. It is.

  The effect of claim 5 is that the control device is composed of a start operation control device and a display operation control device, the start operation is performed by the runner himself, and the time is confirmed by a runner at a measurement location away from the start location. Is to be able to perform another record clerk.

  The time measurement error is mainly caused by detecting a limb located in front of the chest of the runner. For example, a runner with a speed of 8 m / s per second passes with a forward swing width of 0.4 m of the hand or foot. The error in this case is at most about 0.4 / 8 = 0.05 s, and has sufficient accuracy for time evaluation during practice.
