Sit-up intelligent testing device

Abstract

The invention discloses a sit-up intelligent testing device which comprises a sit-up plate and an extension plate which are connected. A knee joint abutting support is arranged on the sit-up plate, and a foot fixing support is arranged on the extension plate; a plurality of pairs of infrared correlation sensors are arranged at the left and right sides of the sit-up plate at intervals in the arrangement mode with the high front part and the low back part, an induction device is arranged at the rear end, away from the knee joint abutting support, of the sit-up plate, the infrared correlation sensors and the induction device are connected with a master control device, the master control device can preset that the multiple pairs of infrared correlation sensors are in the working state, and therefore an infrared stroke induction region matched with the sit-up testing process of a testee can be formed among the multiple pairs of infrared correlation sensors in the working state. The device has the advantages that whether the sit-up motions are standard or not can be judged, and meanwhile the number of sit-ups can be accurately measured.

Description

technical field [0001] The invention relates to a sports testing device, in particular to an intelligent testing device for sit-ups. Background technique [0002] The sit-ups test is a routine item in physical examinations, and usually requires the subject to complete a specified number of sit-ups within a specified time to be considered qualified. Commonly used sit-up testing equipment now includes: sit-up board, low-position sensor and high-position sensor, the front end of the sit-up board is provided with a foot fixing bracket, and the rear end side near the sit-up board is sequentially provided with a low-position sensor The high position sensor, the low position sensor and the high position sensor are respectively connected with the main control device, and the main control device has a counting unit and a timing unit. When in use, the subject lies on the sit-up board, hooks his feet on the foot fixing bracket, and then starts the main control device, the main control...

AI Technical Summary

Problems solved by technology

But when using the above-mentioned sit-up test equipment to test, because when the testee holds his head with both hands, his elbow part is easy to stretch out forward and is positioned at the position in front of the upper body, so there will be elbow first in the process of raising his head. When the upper body triggers the high position sensor, that is: the subject’s upper body has not yet lifted up to the position, but his elbow has already caused the high position sensor to generate a false signal 2. After receiving the false signal 2, the main control device will cooperate with the signal Once a false effective signal is formed, the counting unit will count the false effective signal as a real effective signal, which will make the test results inaccurate
