Problems solved by technology

There are many types of treadmill controls. The current treadmills on the market have very simple functions. Most of them use relays to control the start and stop, and cannot continuously adjust the speed.
Because the running device is relatively expensive, and the processing methods and conditions required by the existing technology are relatively harsh, the existing technology cannot be well adopted, and the identification method for safety is lacking, and the detection system is not perfect, which may lead to misjudgment etc., can not better achieve the purpose of anti-falling

Embodiment 1

[0052] Example 1, such as figure 2 As shown, the ultrasonic ranging probe is used to detect the position and inclination angle of the upper body of the moving human body. Ultrasonic sensors use the echo time to precisely calculate the distance between the sensor and reflective objects. By continuously monitoring distance changes, the speed of movement can also be calculated. The distance detected by multiple position sensors can comprehensively calculate the inclination angle of the object reflecting the sound wave.

[0053] Using the distance information, the driving motor can be controlled to continuously adjust the rotational speed, so that the moving body can be kept in the middle section of the running device. When the moving body runs faster and the upper body approaches the detector, the motor of the treadmill rotates faster; when the running speed of the moving body decreases and gradually moves away from the detector, the machine can slow down. If the movement of ...

Embodiment 2

[0060] Example 2, such as image 3 , Figure 4 As shown, on the basis of Embodiment 1, pedal signal detection can be added. The time difference of the signals between multiple vibration detection probes can be calculated by using the vibration sensor signals, so as to determine the approximate position of the foothold on the pedal. If the two adjacent footholds evenly fall in the safe interval, it indicates that the moving body is in a stable state. If there is a sudden confusion in the stride length or the step interval, it is likely that a motion imbalance has occurred and the control system needs to slow down or stop as soon as possible.

[0061] The calculation of the time difference of the vibration signal is completed by the CPU (single chip microcomputer) of the intelligent control system. After the vibration waveform signal is collected by the AD port, it is obtained through mathematical calculations such as correlation operations.

Abstract

The invention discloses a detection-identification and falling-prevention electronic control device for a running apparatus and a method. The detection-identification and falling-prevention electronic control device comprises a controller, a motor control unit and a detection unit, wherein the controller receives a detection signal of the detection unit by an input end and controls the motor control unit by an output end. The detection unit comprises a distance detection system consisting of at least two distance sensors. The distance sensor is an ultrasonic sensor. The detection unit also comprises a pedal-signal detection system which comprises a vibration sensor; the vibration sensor comprises a plurality of vibration detection probes. The detection unit also comprises a sound detection system. The detection-identification and falling-prevention electronic control device for the running apparatus and the method, disclosed by the invention, have the advantages that the structure is simple, the motion state of a user when the user uses the running apparatus can be accurately judged, the motion speed of the motor can be adjusted in real time, and the intelligent control for the running apparatus can be achieved.

Description

technical field [0001] The invention belongs to the field of running equipment, and relates to an anti-drop electronic control device, in particular to a detection identification and anti-fall electronic control device for running equipment. Background technique [0002] Running is currently an aerobic fitness exercise that is popular internationally and highly appraised by the medical and sports circles. It is one of the most effective ways to maintain physical and mental health, and it is becoming more and more popular. In order to exercise without being affected by external environments such as weather, running equipment has become an essential exercise equipment for many families. [0003] The technology adopted by running exercise equipment is relatively simple at present, and intelligent control device is seldom used. At present, the treadmill has become the most popular indoor fitness equipment in the world. But then more and more people are injured by running. Whe...
