Abstract
The invention relates to the technical field of infant test, and discloses a method for testing the far throw of tennis balls of an infant, wherein during test, a testee stands on an induction plate 2 about far throw after throwing a line, holds an induction tennis ball 5 by hand, and the induction tennis ball 5 emits light; after throwing, when the sensing tennis ball 5 leaves the hand, the sensing tennis ball 5 does not emit light, and when the sensing tennis ball 5 falls into the rectangular strip-shaped sensing blanket, the sensing tennis ball 5 emits light; meanwhile, the far-throw induction plate 2 and the induction blanket transmit potential signals to the distance measurement display device 4 through cables, and the distance measurement display device 4 performs timing, speed measurement and distance measurement; the invention can intelligently test the far-throw tennis of the infant, has simple structure and high accuracy and can lighten the labor intensity of a tester. The tennis racket also can give fun for children to play and prompt the far distance for tennis ball throwing through voice.
Description
Technical Field
The invention relates to the technical field of infant testing, in particular to a method for testing the tennis throw distance of an infant.
Background
Currently, the method for testing the far throw of tennis balls of children is to use tennis balls and a measuring tape for testing. If the landing point of the test ball is between every two transverse lines and every 0.5 m, recording the numerical value marked by the transverse line close to the throwing line; if the accuracy of the test is lost, the tester needs to see and put forward when stepping on or crossing a throwing line, and the tester is hard and labor-intensive.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides a method for testing the tennis throw distance of a child.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for testing the far throw of tennis balls of children comprises the following steps:
when in test, a subject child stands on the induction plate 2 about far away after throwing the line, holds the induction tennis ball 5 by hand, and the induction tennis ball 5 emits light; after throwing, when the sensing tennis ball 5 leaves the hand, the sensing tennis ball 5 does not emit light, and when the sensing tennis ball 5 falls into the rectangular strip-shaped sensing blanket, the sensing tennis ball 5 emits light; meanwhile, the far-throw induction plate 2 and the induction blanket transmit potential signals to the distance measurement display device 4 through cables, and the distance measurement display device 4 performs timing, speed measurement and distance measurement;
when the infant steps on or crosses the throwing line 1, the infrared transmitting and receiving device gives out sound-light alarm, and simultaneously transmits an alarm signal to the distance measurement display device 4 for voice alarm.
Due to the adoption of the technical scheme, the invention has the following advantages:
a method for testing the far throw of the tennis ball of a child can intelligently test the far throw of the tennis ball of the child, has simple structure and high accuracy, and can reduce the labor intensity of a tester. The tennis racket also can give fun for children to play and prompt the far distance for tennis ball throwing through voice.
Drawings
FIG. 1 is a schematic structural diagram of a device for testing the far-throw of tennis balls for infants;
fig. 2 is a schematic top view of the structure of fig. 1.
Detailed Description
The following is a detailed description of specific embodiments with reference to the accompanying drawings.
As shown in fig. 1 and 2, a device for testing the tennis throw distance of a baby comprises: the tennis ball throwing device comprises a far-throwing induction plate 2, an induction blanket 3 and an induction tennis ball 5, wherein a throwing line 1 is arranged at the joint of the far-throwing induction plate 2 and the induction blanket, the induction blanket 3 is a rectangular strip-shaped induction blanket, and scales are arranged on two sides of the rectangle; the far-throwing induction plate 2 and the induction blanket 3 are respectively connected with a distance measurement display device 4 through cables.
The throwing line 1 is an infrared transmitting and receiving device; the timing display device is formed by electrically connecting an input circuit, a timer, a processor, a voice device and a display, and the far-throw induction plate 2 and the induction blanket 3 are induction switches.
