A kind of track timing system based on far-infrared pair tube and using method thereof

Abstract

The invention provides a racing track timing system based on a far-infrared tube pair. The racing track timing system based on the far-infrared tube pair comprises an order issuing device, a race starting detection device, a plurality of timing devices based on the tube pair, a synchronous timing device, a hand-held terminal and a power source module, wherein the order issuing device is used for issuing a starting order, the race starting detection device is used for detecting race starting reaction time and recording race starting time of athletes, the timing devices based on the tube pair are used for recording time that the athletes pass the timing devices, the synchronous timing device is used for resetting initial time of the above devices, and the hand-held terminal is used for receiving the race starting time, the reaction time and the time that the athletes pass the timing devices based on the tube pair and displaying movement data. The racing track timing system based on the far-infrared tube pair has the advantages that rapid alignment of the far infrared tube pair on two sides of a racing track can be achieved by an adjusting method of a five-degree-of-freedom rapid alignment platform, and through coordination of a pressure sensor module and a sound sensor module, the reaction time of the athletes can be measured accurately and rapidly; whether the athletes pass timing points or not is judged by the far-infrared tube pair, and wide racing track time, high precision in timing and good real-time performance can be achieved.

Description

technical field [0001] The invention mainly relates to the technical field of competitive sports statistics, in particular to a track timing system based on far-infrared paired tubes and a method for using the same. Background technique [0002] Timing is an important link in track and field training. The error of timing data directly affects the judgment of athletes' usual running ability and the prediction of competition results. In sprinting, accurate timing is even more important. In normal training, most coaches use two kinds of signals: light signal and sound signal. Due to the instability of the scale of the signal and the inconsistency of the signal source, the timing error is large or small, which interferes with the judgment of the athletes at that time. How to reduce the timing error in sprint training in normal training and master the best timing method is a problem worthy of discussion by track and field coaches. [0003] With the rapid development of electro...

Problems solved by technology

After searching the existing technical documents, it is found that the utility model patent with the Chinese patent publication number CN203397401U discloses a track timing system, which includes a starting point starting device, a finishing point device, and a plurality of student identification devices. The beeping of the buzzer indicates that the running information is initiated, and the identification reading module of the terminal equipment reads the identification information in the student identification equipment through the radio frequency card reader, and establishes the corresponding relationship between the identification information and the timing time. The utility model It can simply measure the running information of multiple athletes, but the use of the buzzer as the starting signal may cause the athletes to not hear the starting signal clearly, and only the running time can be measured, but the starting time, acceleration time and other sports information cannot be measured , it is inconvenient for coaches to learn more about athletes' running information
