[0051] Specific implementation mode two: combination Figure 17 Note that the control circuit 3 in this embodiment includes three signal conditioning circuits, an A / D conversion circuit and a controller 4; the control module is embedded in the controller 4, and the signal input terminals of the three signal conditioning circuits are respectively It is the reference distance signal input end, the front end distance signal input end and the left end distance signal input end of the controller 4; the signal output ends of the three signal conditioning circuits are respectively connected to three analog signal input ends A1, A2 and A3, the digital signal output end of the A / D conversion circuit is connected to the signal acquisition input end of the controller 4, and the A / D conversion control signal output end of the controller 4 is connected to the conversion control signal of the A / D conversion circuit Input end, the signal output end of the pressure sensor 26 is connected to t...

specific Embodiment approach 3

[0054] Specific implementation mode three: combination Figure 17 Note that the control circuit 3 in this embodiment also includes three zero-adjustment circuits, and the three zero-adjustment circuits correspond to three signal conditioning circuits respectively, and the signal output end of each zero-adjustment circuit is connected to a signal conditioning circuit. Zero adjustment signal input terminal.

[0055] This embodiment adds a zeroing circuit. Before actual use, first place the balance training device with information feedback function described in this embodiment on a flat ground, and then keep the pedal 1 in a stable state. At this time, pass The zero-adjusting circuit adjusts the display value of the voltage-driven display to be zero. After the foregoing work is performed, the training is started again, so as to ensure that the measured inclination of the pedal is more accurate.

[0056] In this embodiment, a communication drive circuit 7 can be added, and the s...

Abstract

The information relates to a laser type discus core strength training and motion information feedback monitoring device and solves the problem that the existing discus special technology is short of laser type core strength training methods and motion information feedback monitoring methods. The laser type discus core strength training and motion information feedback monitoring device comprises a discus exerting device and a balance training device with an information feedback function. The discus exerting device comprises an annular rail, a slide telescopic rod, a slide body, as crankshaft connecting rod mechanism, a pressure sensor, two laser speed measurers, a plurality of lifters and a plurality of elastic fixing frames as many as the lifters. The balance training device with the information feedback function is disposed below the annular rail. The balance training device comprises a pedal, a balance base, a control circuit and three distance measuring sensors. The laser type discus core strength training and motion information feedback monitoring device is applicable laser speed measuring discus core strength training and motion information feedback monitoring.

Description

technical field [0001] The invention relates to a discus core strength training and motion information feedback monitoring device, which belongs to the technical field of sports. Background technique [0002] From an anatomical point of view, the core of the human body is the spine, hip joints and pelvis, which are located at the junction of the upper and lower limbs and serve as a connecting hub. Core strength includes core stability strength and core dynamic strength. Core stability strength It refers to the force ability of the core to resist displacement or rotation generated by the intramuscular contraction of the fixed muscles or some fixed muscles that are both fixed muscles and prime movers. Core dynamic strength refers to the force that the contraction of skeletal muscles causes the body to displace or rotate. Core strength is not only the main driving force for the stability of the human core, but also can actively exert force during the flow. Core strength traini...
