Intelligent sit-up assessment system

Abstract

The invention provides an intelligent sit-up assessment system which comprises a gasket for sit-up, the gasket is provided with an intelligent detection assembly, and the intelligent detection assembly comprises a PLC control module, a pressure sensing control module, a laser detection module, a light detection module and a wireless transmission module which are electrically connected. The main technical problem to be solved by the invention is to control the PLC control module to be started by utilizing a pressure sensor on a cushion; whether human body actions are in place or not is judged by utilizing the laser detection module a photoresistor combination mode; in addition, the system integrates a face recognition system, the manual examination of examinee information is replaced, measurement data is uploaded to a cloud platform server through the wireless transmission module, information is organized and sent to an APP client of an examination mobile phone terminal, the whole process does not need the participation of invigilators, and the examination efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of physical fitness testing, in particular to a physical fitness testing device, specifically an intelligent sit-up assessment system. Background technique [0002] Lie on your back on the floor, bend your knees to about 90 degrees, and place your feet flat on the ground. Do not fix your feet on flat ground (for example, your partner presses your ankles with your hands), otherwise the thigh and hip flexors will join in the work, thereby reducing the workload of the abdominal muscles. The assessment and grading standard of student performance is an important part of physical education teaching and one of the key points of the physical education assessment system. [0003] At present, in the assessment of students' physical fitness, in places with poor conditions, one person presses the feet, the other person lies on the mat, and the teacher next to him counts.

Problems solved by technology

[0003] At present, in the assessment of students' physical fitness, in places with poor conditions, one person presses the feet, the other person lies on the mat, and the teacher next to him counts. The standard level of each movement is judged by the naked eye of the monitoring teacher. For some better places, more advanced sit-up testers are gradually adopted, some use photoelectric switches, and some use infrared testers. On the one hand, the position of the movement is judged to determine whether the movement is standard. Although counting has certain simplicity, there are still disadvantages. For example, on-site verification of invigilated exams is required, the exam results cannot be fed back in time, the degree of manual participation is large, the product structure is complex, and the debugging time before the exam is long.
