Embodiment Construction
[0023] Such as figure 1 As shown, the micro-marker point ⑴ is pasted on the selected measuring point on the pedal ⑻. The small three-axis resistance strain rosette ⑵ and the miniature vibration sensor ⑶ (including displacement sensor, speed sensor, acceleration sensor) are pasted and installed on the selected measuring point under the pedal ⑻.
[0024] The response signals of small three-axis resistance strain rosettes (2) and miniature vibration sensors (including displacement sensors, speed sensors, and acceleration sensors) (3) are transmitted to strain gauges (5) and vibrometers (6) through wires, respectively, and then transmitted to the control system after conversion and amplification. The virtual signal analyzer (7) performs analysis and processing according to different needs, and finally obtains the required data, curves, charts and animation displays.
[0025] The calibration and calibration of the entire static and dynamic strain test system and vibration test sys...

The invention discloses an on-line detecting system for pedal response. The on-line detecting system for the pedal response applies the modern measuring technique based on machine vision , combines the modern measuring technique with resistance strain measurement and vibration measurement, uses virtual signal analyzing software and hardware technique, conducts on-line and real-time detections for static-dynamic strain, vibration response and mechanical dynamic characteristic parameters on selected spots, and provides measured data for athlete trainings and development of novel jump pedal. The concrete implementation is that a strain rosette and a vibration sensor are attached on a testing spot under the pedal, relevant signals are transmitted to a strain meter and a vibration meter in a wired or wireless mode, and the signals are transmitted to a signal analyzer after being transformed and amplified. A volume label spot is attached to a testing spot on the pedal to obtain dynamic coordinate value change, a digit camera or a video camera is used to record the dynamic coordinate value change, and the signals are transmitted to the signal analyzer for analysis and process. The detecting system has no influence on the use of the pedal and normal exercises of an athlete. The detecting system can not only be used for the athlete trainings and the on-line detection for wear-force of the pedal and the pedal response, but also is an effective auxiliary means for a novel pedal developer.
Description
technical field [0001] The patent of the present invention adopts miniature marking points, small three-axis resistance strain rosettes, miniature vibration sensors (including displacement sensors, speed sensors, acceleration sensors), digital cameras or digital video cameras, strain gauges, vibrometers and virtual controls. The signal analyzer and other components constitute the pedal response online detection system. [0002] Paste small three-axis resistance strain rosettes and miniature vibration sensors (including displacement sensors, speed sensors, acceleration sensors) on the selected measuring points under the pedal, and use thin leads to transmit the response signals of strain and acceleration to the strain gauge and vibrometer, After conversion and amplification, it is transmitted to a control-based virtual signal analyzer for real-time analysis and processing to obtain corresponding data, curves, charts, and animation displays. [0003] Paste the miniature marking...
