The invention relates to the field of electronic measuring instruments, in particular to a height-feeling device for measuring the height of a human body's jumping height during sports training.

Background technique

The measurement of touch height is an indispensable test in sports training. It is a test of basic physical fitness and ability. It is widely used in school sports, athlete training grounds, etc., especially the measurement of jump touch height in professional training of athletes. Therefore, the data of the test height is required to be accurate.

Using a traditional ruler for manual measurement, due to its error and inconvenient use, has been replaced by a large number of measuring instruments for height measurement. After searching for new patents, patent No. CN94213908.8 discloses an electronic height measurement device, which consists of a sensor circuit. , signal processing controller circuit, numerical display circuit, power supply circuit and instrument shell, the sensor circuit uses a grid-type measuring head, and the two grid bars are turned on by touching to output the measurement signal. It is controlled by a single-chip computer with a measurement control program, processes the measurement signal and outputs the measurement value, and directly displays the measurement height value by the numerical display circuit. It is a measuring instrument with an instrument shell, which can be made portable, easy to use, and has accurate measurement values. Its power supply can be dry batteries or commercial power.

Patent No. CN200610098134.7 discloses an electronic touch height automatic measurement and analysis device and its working method. The device includes a sensing component, a data processing component and an output component that are electrically connected in sequence. The sensing part is a mechanical touch switch or a capacitive sensing switch or an optical path blocking switch, which is used to obtain touch height data and is fixedly connected with the shell; the data processing part is an embedded module, which is composed of an interface part and a single-chip microcomputer for Receive the touch height data, process and analyze it; the output part contains a display, voice prompter and data transmission interface, which is used for digital display and voice prompt touch height value, and sends the digital signal processed by the data processing part to the upper position computer. The working method includes receiving and processing the switch signal of the sensor component, setting the working state of the device, generating a data processing mode, processing the received touch height or clear height data and forming a database, and judging the physical fitness of the measured person based on this Or for athletes to select materials and guide scientific training.

Thus, by hand touching the grid-type measuring head or touch switch, capacitive induction switch, or optical path blocking switch, conduction and output touch height measurement value signals are generated, and the measurement output signals are processed to display values or voice prompt values.

For example, Patent No. CN200820093816.3 discloses a jumping touch height device. A touch switch is provided at a position corresponding to the height value of the height touch plate marked with a height value. An indicator light is arranged in the touch switch. connect. It also belongs to this type of touch switch.

The above-mentioned patents show that neatly arranged grid strips or strip-shaped mechanical touch switches, capacitive sensing switches, and optical path blocking switches are used as sensing components. Most similar products on the existing market use this type of technology and hang Wall type touch height.

However, the touchpad is fixed along the wall, and the touchpad is on the hard surface of the wall. When the tester jumps and touches the height, especially when the run-up touches the height, the arm is easy to be injured due to the forward impact; Obstacles, don't want to hit the wall and get hurt. Since this touch panel is fixed along the wall, only the standing take-off method can be selected when touching the height, which is very different from the approaching take-off method.

At the same time, touch switches and other methods cannot retain touch traces, and the test results can only be displayed on the display screen, or the indicator light on the touch switch is on. If there is a machine failure, or when the tester doubts the test results, retesting cannot be performed. , the data display is "too small" or "not bright", and it is also easy to cause difficulties in recording results.

For this reason, in view of the problems and defects existing in the existing mogao device, the technical structure and manufacturing method of the mogao device are improved, which can not only measure the height accurately, but also record and display the data, which can be reviewed.
