Intelligent standing long jump board based on flexible array pressure sensor and working method of intelligent standing long jump board

Abstract

The invention provides an intelligent standing long jump board based on a flexible array pressure senor. The intelligent standing long jump board comprises a sensing element, a central processing module, a long jump board body, a take-off board and a handheld device, wherein the sensing element is the flexible array pressure sensor and laid on the surface of the long jump board body, a test area is formed, and the sensing element is used for detecting sensing signals produced in the stepping and pressing position when the test area is stepped and pressed and sending the sensing signals to the central processing module; the central processing module collects the sensing signals and calculates and outputs long jump performance, a transmission module transmits the long jump performance to the handheld device for display and voice broadcast; the take-off board is used for determining the take-off position; the handheld device is used for storing, managing, displaying and broadcasting the long jump performance. According to the intelligent standing long jump board based on the flexible array pressure senor, the flexible array pressure senor is adopted as the sensing element, the detection precision, the reliability and the stability are higher, the long jump test range can be set, and the intelligent standing long jump board is convenient to carry and use and supports wireless transmission and download of data.

Description

technical field [0001] The invention relates to the technical field of sports electronic measurement, in particular to an intelligent standing long jump board based on a flexible array pressure sensor. Background technique [0002] The measurement of long jump distance is an indispensable test in sports training. Long jump can test the explosive power of human legs. It is a test of basic physical fitness and ability. It is widely used in students' physical fitness test, physical exercise, professional training of athletes and soldiers In many fields, such as talent selection, competitive sports scientific research, etc., especially in the long jump measurement in professional training of athletes, the measurement of long jump distance is required to have high accuracy. [0003] The traditional long jump test is mainly to draw a jump line on the ground, place a ruler next to it, and measure the long jump performance by naked eye readings. This method has large errors, and da...

AI Technical Summary

Problems solved by technology

[0007] 1. This kind of long jump board using the light sensor group as the sensing element judges the foot position by means of infrared blocking, but the accuracy of this method is still low (as stated in the patent document, the sensor installation distance in the light curtain is 1cm );

[0008] 2. This kind of long jump board that uses the light sensor group as the sensing element has a large detection angle range of the infrared sensor, and the infrared rays have a certain penetration, which further reduces the accuracy of the measurement

[0009] 3. This kind of long jump board using the light sensor group as the sensing element has a large number of sensors and troublesome installation. The standing long jump test pad and the host are large in size and inconvenient to carry

[0012] 1. This kind of traditional long jump distance measurement display instrument uses a mechanical touch switch as the sensing element for the detection of long jump distance. Long-term use will lead to failures such as fragile switches, variable insensitivity, etc., resulting in reduced measurement accuracy. Anomalies such as low measurement stability;

[0013] 2. This traditional long jump distance measurement display device still has problems such as bonding failure, poor contact and false alarms;

[0014] 3. This kind of traditional long jump distance measurement display instrument can not store the user's training data, let alone support networking. In today's intelligent society, it cannot meet the needs of users.
