Description

Novel automatic range finding score of javelin target device

Technical Field

The invention relates to a novel automatic ranging and scoring device for a javelin target, mainly relates to a device adopting a novel portable javelin target and automatic ranging and scoring, and belongs to the field of automatic machinery.

Background

In the modern society, the sports industry gradually becomes a global industry through events such as sports, olympic games and sub-sports games, and in the sports events, a plurality of referees and various instruments are always arranged for the sake of fairness.

The invention relates to an automatic ranging and scoring device for a javelin target, which transmits data to a display through the cooperation of a telescopic target disc and a central laser range finder, saves manpower and material resources, and ensures the accuracy of scores and the fairness of competitions.

Disclosure of Invention

The invention aims to provide an automatic ranging and scoring device for a javelin target, which can automatically range and score.

The invention aims to solve the problems that the existing javelin match is inconvenient in distance measurement and scoring, and wastes time and labor.

In order to realize the purpose of the invention, the technical scheme adopted by the invention is as follows:

novel automatic range finding of javelin target score device, including target dish, central distancer, elevating platform, laser range finder, flexible top cap, display, camera, control chip, remote controller and starting point laser searchlighting appearance, the target dish lays on the field, and central distancer passes through the buckle and fixes with the dish center, and screw connection control chip is on central distancer, and the elevating platform passes through the transfer line to be fixed in central distancer top, and laser range finder places on the elevating platform post through the draw-in groove, and the flexible top cap of distancer top welding, display pass through bolted connection fixed with the target dish edge, camera record measurement process, remote controller control elevating platform, whether starting point laser searchlighting appearance searchlighting is broken rule more.

The invention has the advantages that: in the javelin motion, novel javelin target automatic ranging scoring device judges automatically foul judge, automatic range finding, automatic total mark, system processes such as automatic record, has improved javelin judge's accuracy and efficiency greatly, in the modern that sports was paid attention to increasingly, has wide market space.

Detailed Description

The invention is further explained below with reference to the drawings and examples.

As shown in the figure, novel javelin target automatic ranging scoring device includes target disc 1, central distancer 2, elevating platform 3, laser range finder 4, flexible top cap 5, display 6, camera 7, control chip 8, remote controller 9 and starting point laser searchlighting appearance 10, characterized by: when the javelin is inserted into the target disc 1, the target disc 1 is made of flexible foam and can be repaired and used for multiple times, the control chip 8 controls the central distance meter 2 through the remote controller 9, a signal pulse sends out an instruction, the remote controller 9 has three functions of ascending, descending and resetting, the ascending, descending and home position recovery of the lifting platform 3 are controlled, the lifting platform 3 adopts hydraulic pressure to ascend and descend, the power is stable, the annular laser distance meter 4 arranged on a lifting column is opened during measurement, the laser distance meter 4 emits scanning distance covering radius within 10 meters, the whole target disc is scanned during annular distance measurement, distance measurement is carried out after the positioning is successful, the calculation mode is that the vertical distance from a landing point to a starting point is measured, the vertical distance is displayed on the display 6 after the measurement and calculation is finished, the display 6 is a waterproof panel and a toughened display screen, after the measurement and calculation is finished once, the lifting platform 3 descends until the flexible top cover 5 is parallel to, the flexible top cover 5 is made of anti-smashing materials, an internal system is protected, the camera 7 records the whole measuring process, the competition fairness is guaranteed, the starting point laser detector 10 is prevented from throwing at a point, and if an offline foul is found, an alarm is given and fed back to the display to display the result invalid.

The using method of the device comprises the following steps: the power switch is turned on, the target plate 1 is tiled for use, when a javelin is inserted into the target plate 1, a judge can remotely control to carry out distance measurement and scoring, the control chip 8 controls the central distance meter 2 to control the lifting platform 3 to ascend to a specified height through the remote controller 9, the annular laser distance meter 4 is immediately turned on to release laser to measure and score the distance between the javelin and a take-off line, if the javelin is thrown out in a specified range, the javelin cannot be scanned, no score exists, the javelin is judged to be a foul, the distance is displayed on the display 6 after measurement and calculation is finished, the camera 7 records the whole measuring process, the judge can record, after one measurement and calculation is finished, the lifting platform 3 is controlled to descend to the position where the flexible top cover 5 is parallel to the target plate 1 through a pulse remote controller signal of the judge, the next measurement and the laser detector 10 sends an alarm when the rule is crossed.
