Description
Technical field
The present invention relates to the Split Time velocity-measuring system based on WLAN (wireless local area network), belong to technical field of sports apparatus.
Background technology
Split Time refers to and in physical culture track, completes one period that specific distance is used, and it is the concept corresponding with terminal timing.Any terminal achievement can be regarded the cumulative of its numerous spilt times as, and in the situation that other states remain unchanged, the raising of any spilt times will cause the raising of terminal achievement.Therefore,, in Modern Exercise Training, various countries trainer attaches great importance to the research of Split Time achievement.
In order to address the above problem, China Patent Publication No. CN2116925U publication dates 19920923 denomination of invention be " photoelectricity Split Time device ", the T.T. that can measure one section of motion distance, can not realize the function of Split Time and wirelessly transmitting data.
China Patent Publication No. CN1071267A publication dates 19930421, denomination of invention was " wireless telecontrol velocity measuring system for training athlete by segmental timekeepings ", although can realize Split Time function, but its wireless device is made up of transmitting unit and two parts of reception unit, and transmitter and receiver circuit complexity, wireless launcher and receiving trap are not combined into a circuit module, do not adopt wifi module or the zigbee module of main flow on market, the distance of wireless transmission and the stability of equipment are affected, this utility model at most also can only arrange ten points of segment distances, can not meet as the isometric demand of the omnidistance motion process of sportsman being monitored apart from sports events needs of speed skating.
China Patent Publication No. CN201532660U publication dates 20100721, denomination of invention was that " the track Split Time system based on line array CCD " is by compositions such as video camera, video recorder, monitors, this kind equipment is huge, expensive, use is complicated, be suitable for big event, but cannot popularization and application in training athlete and teaching.
Summary of the invention
For the problem of above-mentioned existence, the object of the present invention is to provide a kind of stable, accurate timing, convenience, economy and there is the Split Time velocity-measuring system of wirelessly transmitting data function.
To achieve these goals, its technical solution is:
Split Time velocity-measuring system based on WLAN (wireless local area network), radio segment timing velocity-measuring system is made up of timer more than two, timer is made up of the infrared launcher and the infrared receiving device that are separately positioned on support, infrared launcher and infrared receiving device are in same level, and the surface of emission of infrared launcher is relative with the receiving plane of infrared receiver to be arranged, infrared receiver is provided with infrared receiver sensor, one-chip computer module, wireless module, the signal wire of infrared receiver sensor is connected with the IO port of one-chip computer module, wireless module is connected with one-chip computer module IO port.
Infrared emitting sensor in described infrared launcher and infrared receiver and infrared receiving sensor are infrared emission photoelectric sensor, and wireless module is wifi module or zigbee module.
The spacing of the two adjacent groups timer of the described Split Time velocity-measuring system based on WLAN (wireless local area network) is 1m ~ 100m.
Owing to adopting above technical scheme, Split Time system of the present invention has realized the timer that pulse signal that one-chip computer module gathers the output of infrared emission photoelectric sensor triggers one-chip computer module and has started timing, the function of wireless module passing time data.When tester passes through first group of timer, the infrared ray of infrared launcher transmitting is blocked, can there is the variation of a low and high level in the output signal of the infrared receiver sensor in infrared receiving device, the IO port in one-chip computer module with interrupt function captures the variation of infrared receiver sensor output level, and wireless module sends first zone bit to terminal device by LAN (Local Area Network) simultaneously.Terminal device starts timing after receiving first zone bit.In the time that tester passes through second group of timer, single-chip microcomputer IO port captures the pulse signal of infrared receiver sensor output, the wireless module of second group of timer sends second zone bit to terminal device by LAN (Local Area Network), the mistiming that terminal device receives two zone bits is tester by the time of first segmentation, same method, can collect tester by the time data of other segmentations, if measure again the distance of each segmentation, can also calculate the average velocity of segmentation.
The present invention is reasonable in design, simple in structure, accurate timing, easy to use, can be in track and field, speed skating project, monitoring moving person, in time, the velocity variations rule of segmentation, can also test athletic turning back run ability in the court games such as football, basketball, rugby.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See accompanying drawing
A Split Time velocity-measuring system based on WLAN (wireless local area network), Split Time velocity-measuring system is made up of timer more than two.Timer is made up of the infrared launcher 1 and the infrared receiving device 2 that are separately positioned on support 3, infrared launcher 1 and infrared receiving device 2 are in same level, and relative arrangement of receiving plane of the surface of emission of infrared launcher 1 and infrared receiver 2.Infrared receiver comprises infrared receiver sensor 4, one-chip computer module 5, and wireless module 6, the output signal line of infrared receiver sensor 4 is connected with the IO port of one-chip computer module 5, and wireless module 6 is connected with the IO port of one-chip computer module 5.
