Segmented timing velocity measuring system based on wireless local area network

Abstract

The invention relates to a segmented timing velocity measuring system based on a wireless local area network and belongs to the technical field of sports equipment. An exercise training segmented timing system consists of at least two groups of timers, each timer consists of an infrared emission device and an infrared receiving device which are arranged on a support respectively, the infrared emission devices and the infrared receiving devices are located on the same horizontal plane, emission surfaces of the infrared emission devices and receiving surfaces of the infrared receiving devices are arranged oppositely, the infrared receiving devices are provided with infrared receiving sensors, single-chip microcomputer modules and wireless modules, signal lines of the infrared emission sensors are connected with IO (input / output) ports of the single-chip microcomputer modules, and the wireless modules are connected with IO ports of the single-chip microcomputer modules. Each timer performs communication through the wireless modules, and measured time and velocity data are sent to terminal equipment through the wireless modules. The segmented timing velocity measuring system is reasonable in design, simple in structure, accurate in timing and convenient to use.

Description

technical field [0001] The invention relates to a segmented timing speed measurement system based on a wireless local area network, and belongs to the technical field of sports equipment. Background technique [0002] Split timing refers to the time it takes to complete a specific distance in a sports track, and it is a concept corresponding to finish timing. Any final result can be regarded as the accumulation of its countless sub-segments. Under the condition that other states remain unchanged, the improvement of any sub-score will inevitably lead to the improvement of the final result. Therefore, in modern sports training, coaches from all over the world attach great importance to the study of segmented timing performance. [0003] In order to solve the above-mentioned problems, the Chinese Patent Publication No. CN2116925U Published Date 19920923 The invention name is "photoelectric segmented timer", which can measure the total time of a movement distance, and cannot re...

Problems solved by technology

[0003] In order to solve the above problems, Chinese Patent Publication No. CN2116925U publication date 19920923 invention name is "photoelectric subsection timer", which can measure the total time of a section of motion distance, but cannot realize the functions of subsection timing and wireless transmission of data

[0004] Chinese Patent Publication No. CN1071267A Publication Date 19930421 The name of the invention is "wireless remote control segmentation timing speed measurement system for track athlete training". And the circuit of the transmitter and receiver is complicated, the wireless transmitting device and the receiving device are not combined into one circuit module, and the mainstream wifi module or zigbee module on the market is not used, which affects the distance of wireless transmission and the stability of the equipment. This utility model Only ten segment distances can be set at most, which cannot meet the needs of long-distance sports such as speed skating that need to monitor the entire movement process of athletes

[0005] Chinese Patent Publication No. CN201532660U Publication Date 20100721 ​​The title of the invention is "Segment Timing System for Track Race Based on Linear Array CCD" which is composed of cameras, video recorders, monitors, etc. This type of equipment is huge, expensive, and complicated to use, and is suitable for large-scale competitions. However, it cannot be widely used in athlete training and teaching
