Automatic timing sports stopwatch

Abstract

The invention discloses an automatic timing sports stopwatch. Thesports stopwatch comprises a plurality of identity identification cards and an identification recording device matched with the identity identification cards, the identification recording device comprises a base box, a timing control panel and a sealing cavity are arranged in the base box, and the side end of the sealing cavity is connected with a control window in a penetrating manner; a winding motor is fixedly connected to the bottom wall of the inner cavity of the sealing cavity, a winding roller is rotatably connected to thewinding motor, treading cloth matched with the control window is wound around the winding roller, a plurality of recognition sensors matched with the identity recognition cards are evenly arranged inthe treading cloth, and a fixed anchor roller is fixedly connected to the movable end of the treading cloth; and the rear side end of the base box is rotationally connected with a pressing roller assembly matched with the treading cloth, and the timing control panel is connected with the display screen and all the recognition sensors. The whole automatic timing device is simple in structure and can be rapidly unfolded or folded, the laying convenience of the whole device can be greatly improved, and application and popularization of the whole device are facilitated.

Description

technical field [0001] The invention relates to the technical field of sports stopwatches, in particular to a sports stopwatch with automatic timing. Background technique [0002] A stopwatch is a commonly used time measuring instrument. It can also be called "mechanical stop watch". It consists of a pause button, a mainspring handle, a minute hand, etc. It is timed by using the isochronism of the pendulum to control the rotation of the pointer. There are two main categories of stopwatches: mechanical and electronic, and electronic watches can be divided into two categories: three-button and four-button. The electronic stopwatch is a more advanced electronic timer. The domestic electronic seconds generally use the oscillation frequency of the quartz oscillator as the time reference, and use 6-digit liquid crystal numbers to display the time. It has the advantages of intuitive display, convenient reading, and multiple functions. . [0003] In the field of sports, a stopw...

Problems solved by technology

The traditional stopwatch is manual timing. This kind of stopwatch is simple and easy to carry, but it is difficult to record. The accuracy depends on the referee, which relies heavily on people, and is not suitable for games with a large number of people; Automatic timing stopwatch, although the recording accuracy has been greatly improved, and can meet the competition needs of a large number of people, but it needs a variety of equipment to assist, the laying is difficult, and it requires a long preparation work, and the application is very inconvenient
