As shown in fig. 1, 2, 3 and 4
The electric treadmill is also called as an electric walking machine, and the electric treadmill and the electric walking machine are generally called as the electric treadmill in the industry. The electric treadmill generally comprises a running board, wherein the running board comprises a running board body, a running belt 4, a running board supporting structure, a frame edge 1 at the front end and frame edges 3 at the side edges of the running board at two sides, wherein the running belt 4 is covered outside the running board body, is driven by a motor and is tensioned and driven by a front roller and a rear roller. The running board can be a folding running machine, for example, a running machine adopting loose-leaf folding front and back running boards in the prior art, or a running machine adopting a prior art that a front running board and a rear running board are connected and folded in a sliding way through an arc-shaped track, or a folding running machine adopting the folding mechanism for the running board of the running machine and the folding running machine in the prior invention patent application of the folding mechanism for the running board of the running machine with the patent name of 201811441466.X in the applicant of the invention. In addition, athletes are also referred to within the industry as runners or walkers.
The invention relates to a speed control method of an electric treadmill, which comprises the following steps:
the electric treadmill is provided with a controller and an ultrasonic sensor for detecting the foot area of a sporter positioned above the running board during the exercise;
ultrasonic sensor launches the ultrasonic wave to running board top, and the echo signal is received, the ultrasonic wave meets sporter's foot and can take place the reflection, received by ultrasonic sensor, the controller is through analysis echo signal, judge the distance between sporter's foot and ultrasonic sensor, because sporter's motion is gone on one by one step on the running board, consequently the distance between sporter's foot that detects and the ultrasonic sensor possesses the periodicity, in every cycle, when the farthest distance of sporter foot and ultrasonic sensor detected, this position is the focus position of sporter this moment, do following control to the treadmill according to sporter's focus position:
the gravity center position of the sporter is positioned in a preset acceleration area, and the controller controls the motor to accelerate;
the gravity center position of the sporter is positioned in a preset constant speed area, and the speed of the motor is controlled to be constant by the controller;
the center of gravity position of the sporter is positioned in a preset deceleration zone, and the controller controls the motor to decelerate.
The ultrasonic sensor sends sampling pulses and detects echo signals, the controller calculates the distance between the feet of the sporter and the ultrasonic sensor according to the time of sampling and detecting the echo signals to form a waveform diagram with the ordinate as the distance and the abscissa as the time, each peak point in the waveform diagram indicates that the feet of the sporter are farthest away from the ultrasonic sensor at the moment in the period, namely the distance value is the gravity center position of the sporter at the moment.
If the ultrasonic sensor 2 continuously detects and outputs the detection result pulse to the MCU, the MCU detects and outputs the preset times per second in each period, the MCU calculates the real-time distance between the feet of the runner such as the tiptoes and the ultrasonic sensor 2 according to the pulse width and forms a waveform diagram, the last peak point in the first second is the actual gravity center position of the runner, then a peak point is taken in each step, the peak point is also the gravity center position of the runner, the peak points are the peak point in the first second and the peak point taken in each step are positioned in the preset acceleration area 5, and the MCU controls the motor speed regulator to accelerate the motor. The peak point is positioned in a preset constant speed area 6, and the MCU controls the motor speed regulator to enable the motor speed to be unchanged. The peak point is positioned in a preset deceleration area 7, and the MCU controls the motor speed regulator to decelerate the motor. In practice, as mentioned above, the peak point is the gravity center position of the runner, and it can be understood that the feet are parallel and at the same time the distance between the feet and the ultrasonic sensor 2 is equal. Also, as can be seen from fig. 1, the peak is farthest from the ultrasonic sensor 2, and the trough, i.e., the bottom, is closest to the ultrasonic sensor 2.
And then, the MCU can be preferably an MCU of which the model is STM8S 005. The ultrasonic sensor 2 also has various starts for detecting and outputting detection result pulses, for example, the MCU can output pulses every 20 microseconds, namely 20us width at the triger pin to trigger the ultrasonic sensor 2, after the ultrasonic sensor finishes detecting, the MCU can output a detection result pulse through the echo pin, the pulse width is in proportional relation with the detection distance, and the MCU calculates the real-time distance between the feet of the runner, such as the toe, and the ultrasonic sensor according to the pulse width.
The acceleration zone 5 is 3/11 segment of the running belt 4 located on the upper plane and close to the ultrasonic sensor, which can also be called front 3/11 segment, such as 0-30 cm from the ultrasonic sensor 2. The constant speed area 6 is 2/11 section of the running belt 4 located on the upper plane and close to the acceleration area 5, which can also be called a middle section, for example, 0-20 cm away from the acceleration area 5. The deceleration zone 7 is 2/11 segments of the running belt 4 which is positioned on the upper plane and is close to the constant speed zone 6, and can also be called as middle two segments, for example, 0-20 cm away from the constant speed zone 6. It may also comprise an activation zone, said activation zone preferably coinciding with the acceleration zone 5 described above, i.e. the activation zone is preferably the same area as the acceleration zone. And an emergency stop zone 8 can be further included, wherein the emergency stop zone 8 is 4/11 section of the running belt 4 positioned on the upper plane and close to the deceleration zone 7, which can also be called rear 4/11 section, such as 0-40 cm from the deceleration zone 7.
The upper paragraph can do this understanding; although the running belt 4 rotates around the running board body during operation, the running belt located on the upper plane is a definite concept, namely, the running belt is divided into a front section 2/11, a middle section 2/1 and a rear section 4/11 in the front 3/11 according to the length direction as long as the running belt is located on the upper plane of the running board body. It is of course also understood that the tread band in the upper plane is located opposite the front 3/11 of the frame 3 of the side of the treadmill in one section 2/11 and in two sections 2/1 and in the rear 4/11. In other words, the running belt 4 is divided into an acceleration area 5, a uniform speed area 6, a deceleration area 7 and an emergency stop area 8 in the length direction relative to the frame 3 on the running board side, and the running belt 4 is further divided into a starting area in the length direction relative to the frame 3 on the running board side, but the starting area preferably coincides with the acceleration area 5.
The transverse lines marked on the frame edges 3 of the two side edges in the length direction of the running board in fig. 2 can be understood as folding lines of the front running board and the rear running board, which are not precise, but the drawings are only schematic. The first short transverse line at the front end of the folding line on the frame edge 3 on the right side edge is the boundary line between the display front 3/11 and the middle section 2/11, and distinguishes the acceleration area 5 from the constant speed area 6; the second short transverse line at the front end of the folding line on the frame edge 3 on the right side edge is a boundary line between the middle section 2/11 and the middle section 2/11, and is used for distinguishing the constant speed area 6 from the deceleration area 7; a short transverse line at the rear end of the fold line in the right side frame 3 is the boundary between the middle section 1/3 and the rear section 4/11 of the display, which distinguishes the deceleration zone 7 from the scram zone 8.
When the electric treadmill is powered on but still in a stopped state, the ultrasonic sensor 2 detects that the center of gravity position of the exerciser is in the start area, and the controller controls the motor to start. If the electric treadmill is powered on but still in a stopped state, the last peak point in the first second detected and outputted by the ultrasonic sensor is in the start area, and the motor is started.
When the electric treadmill is operated, the motor stops operating while the motor is decelerated for a predetermined time, such as 3 seconds, 4 seconds, 5 seconds, 6 seconds, etc. Or decelerating to a predetermined speed, such as 1 km/h or 1.1 km/h or 1.2 km/h or 1.3 km/h or 1.4 km/h, and the like, and stopping the operation of the motor.
The electric treadmill starts, accelerates, decelerates, or stops, and the change of adjacent programs is smooth transition. I.e. in general not very abruptly starting, accelerating, evening, decelerating or stopping.
The preset number of times of detection and output per cycle, such as per second, is preferably 50 times. In other words, the preset number of times of detection and output for 2 seconds is preferably 100 times. Of course, the preset millisecond of each time of the ultrasonic sensor may also be used to acquire information once in 21 millisecond, or 22 millisecond, or 23 millisecond, or 24 millisecond, or 25 millisecond, or 26 millisecond, and each time is used for acquiring a waveform at several points acquired in a predetermined time period, such as acquiring a waveform at 50 points within 1 second time period, such as acquiring a waveform at 100 points within 2 second time period, such as acquiring a waveform at 150 points within 3 second time period … …. It is understood that the detection, i.e. grabbing is continuously performed, when the value rises, the maximum value, i.e. the peak point, is grabbed, the inflection point is found, and if 5 grabbing points continuously fall all the time, the maximum value is determined to be effective; on the contrary, when the value is decreased, the minimum value, namely the valley point, namely the wave bottom is grabbed, the inflection point is found, and if 5 grabbed points are continuously increased, the minimum value is determined to be effective.
When the electric treadmill is operated, the ultrasonic waveform is not detected for a predetermined time such as 1 second, 2 seconds, 3 seconds, etc., and the motor stops operating. When the motor-driven treadmill is operated, a stationary object is detected for a predetermined time, for example, 1 second, 2 seconds, or 3 seconds, and the motor is stopped. After the steps are adopted, the speed control method of the running machine has good error correction control, and even if the running machine runs, the running of the motor is stopped as long as the ultrasonic wave is not detected in the preset time, for example, a runner leaves the running machine. Or, when the running machine runs, the preset time is detected to be that a static object such as a person suddenly folds the running machine to block the ultrasonic signal, or other static objects suddenly fall on the running machine by mistake, and the running of the motor can also be stopped. The safety of the equipment is well ensured.
The peak point is in the sudden stop area and the speed is reduced to 0 within a preset time, for example, the speed is reduced from 3 km/h to 0 km/h within 3 seconds, and the motor stops running.
The ultrasonic sensor 2 is arranged on the frame edge 1 at the front end of the running board and is positioned in the middle of the width direction of the running belt 4, and the ultrasonic wave is transmitted and received towards the toe direction of a runner.
The axis extension line of the ultrasonic sensor is inclined upwards, and the inclined angle is 2-10 degrees between the axis extension line of the ultrasonic sensor and the horizontal plane. For example, it may be preferred to have 2 ° or 3 ° or 4 ° or 6 ° or 7 ° or 8 ° or 9 ° or 10 °, most preferably 5 °.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
