Abstract
The utility model discloses a tennis ball over-net speed meter which comprises an infrared transmitter, an infrared receiver, a data acquirer and a data processor. The infrared transmitter transmits infrared rays through an infrared transmission terminal; the infrared receiver receives the infrared rays transmitted from the infrared transmission terminal correspondingly through an infrared receiving terminal; the infrared rays positioned on the same vertical plane form at least two pieces of infrared net which are parallel to a partition net; the data acquirer acquires information of breakpoint position and time received by the infrared receiver and then transmits the acquired information to the data processor; and the data processor calculates and analyzes the received information so as to acquire information of tennis ball speed. The tennis ball over-net speed meter can realize monitoring parameters such as tennis ball over-net speed and tennis ball moving track in real time, and is a wide-spread effective scientific aid designed for confrontation games utilizing partition nets.
Description
Technical field
The utility model relates to a kind of sport category auxiliary detection device, relates in particular to a kind of tennis overpass speed analyzer.
Background technology
In filter class antagonism project, the net spee of crossing of ball has directly reacted athletic ball-hitting quality and batting level, by understanding crossing net spee and can providing direct basis to the correction of training athlete method of ball, and at present not to the device that net spee carried out directly crossing indirect detection of crossing of ball.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of tennis overpass speed analyzer, and overpass speed is carried out determination and analysis, makes things convenient for the coach that athletic training method is revised.
Technical scheme: for achieving the above object, the technical solution adopted in the utility model is:
A kind of tennis overpass speed analyzer comprises infrared launcher, infrared receiving device, data acquisition unit and data processing equipment: described infrared launcher is by infrared emission end emission infrared ray; Described infrared receiving device receives the infrared ray of corresponding infrared emission end emission by infrared receiving terminal; The infrared ray that is positioned at same vertical plane consists of infrared wire side, and the number of described infrared wire side is more than the two sides, and all is parallel to filter; Described data acquisition unit gathers breakpoint location information and the breakpoint temporal information that infrared receiving device receives, and sends Information Monitoring to data processing equipment; Described data processing equipment carries out computational analysis to the information that receives, and obtains the velocity information of overpass.
After using said apparatus, overpass will inevitably be passed all infrared wire sides, when overpass and infrared wire side intersect, make the infrared emission end produce breakpoint to the infrared ray of infrared receiving terminal emission, because the number of infrared wire side is more than the two sides, just just can simulate the net state information of crossing of overpass by analyzing breakpoint location information and breakpoint temporal information, comprise the velocity information of overpass.The simulation accuracy of crossing net state information is depended on the factors such as infrared ray arrangement mode, infrared ray density (comprising infrared ray number and spacing and arrangement mode on the number of infrared wire side and spacing, the every flushing outer wire side), data acquiring frequency.
Preferably, the infrared emission end of described infrared launcher becomes array arrangement, such as orthogonal array, rhombus array, circular array etc., but require its formed infrared wire side to want enough large, the assurance overpass can both be passed all infrared wire sides in large as far as possible probable range; The infrared ray direction that described infrared emission end is launched can the position level form one group of parallel lines of mutually noninterfere, also can be staggered to form wire side, certainly the design of infrared receiving device will adapt to the design of infrared launcher, generally design corresponding infrared receiving terminal at ultrared end, and without processes such as mirror-reflection or data processing.
Preferably, the infrared emission end of described infrared launcher becomes 5 rows, 3 row formula rectangular arrays to arrange, and the line space between the infrared emission end and column pitch be 5cm, and the infrared ray diameter that the infrared emission end is launched is 1cm; Certainly this is a kind of optimal way of our design, also can design the more rectangular array arrangement mode of multiple row of more rows, and the spacing between the infrared emission end and the infrared ray diameter of launching also can adopt preferred scheme.
Preferably, also comprise data memory module, described data memory module is stored the data that data harvester and data processing equipment obtain, produce.
Preferably, also comprise overpass Actual Simulation module, described overpass Actual Simulation module is simulated the network process of crossing of overpass according to the result of data processing equipment computational analysis, and shows by display unit.
Preferably, also comprise support, described infrared launcher and infrared receiving device all are fixed on the support.
Beneficial effect: tennis overpass that the utility model provides speed analyzer, can the Real-Time Monitoring ball crossing speed when netting and the parameters such as movement locus of ball; Can also relevant parameter be shown in the mode of chart and numeral that simultaneously reflect ball at the state of crossing when netting, to the grasp of ball speed, convenient coach made more reasonable, perfect drill program in the training and competition process for convenient coach and referee comprehensively; Be a kind of for all kinds of filter classes antagonism projects design extensively, effectively, the servicing unit of science.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Be a kind of tennis overpass speed analyzer as described in Figure 1, comprise infrared launcher, infrared receiving device, data acquisition unit and data processing equipment, described infrared launcher and infrared receiving device all are fixed on the support, and the below is specifically described with regard to various piece.
Described infrared launcher is by infrared emission end emission infrared ray, described infrared emission end becomes 5 rows, 3 row formula rectangular arrays to arrange, and line space and column pitch between the infrared emission end are 5cm, and the infrared ray diameter that the infrared emission end is launched is 1cm, infrared ray direction position level.
Described infrared receiving device receives the infrared ray of corresponding infrared emission end emission by infrared receiving terminal, described infrared receiving terminal arrange suitable with the infrared emission end.
The infrared ray that is positioned at same vertical plane consists of infrared wire side, and the number of the infrared wire side in this case is three, and all is parallel to filter.
Described data acquisition unit gathers breakpoint location information and the breakpoint temporal information that infrared receiving device receives, and sends Information Monitoring to data processing equipment; Described data processing equipment carries out computational analysis to the information that receives, and obtains the velocity information of overpass.
Software section in this case also comprises data memory module, overpass Actual Simulation module, name input module etc.Described data memory module is stored the data that data harvester and data processing equipment obtain, produce.Described overpass Actual Simulation module is simulated the network process of crossing of overpass according to the result of data processing equipment computational analysis, and shows by display unit.Described name input module is used for the right sportsman of data that difference gathers, and preferably related data can be distinguished with name, is convenient to the later stage use.
