Similarly, this method does not really extract the acceleration characteristics of the runner. The runner may just step on it accidentally. This is because if the acceleration or deceleration is accelerated or decelerated, the runner will be in danger of falling, which is not safe or smart enough.

Embodiment Construction

[0019] Such as figure 1 As shown, the flexible array pressure sensor 1 is fixed on the upper side of the running board 7, and a protective layer is pasted on the flexible array pressure sensor 1, and a wear-resistant layer is fixed on the protective layer, which is used to isolate the running of the treadmill during running. Friction with 6, protecting the flexible array pressure sensor 1.

[0020] Such as figure 2 As shown, a computer control module is installed in the tablet computer 2, which receives in real time the runner's stride frequency, step length, time of support, time of vacating, and back pedaling force transmitted by the data acquisition transmission module 3;

[0021] The machine learning is as follows: in a static state, the runner stands on the treadmill, collects the body weight m, and then the runner runs at the two speed values ​​(8km / h, 10km / h) that have been set for 3 minutes, and at the same time flexibly The array pressure sensor will collect parame...

Abstract

The invention discloses a self-adaptive speed regulation system of running device based on a flexible array pressure transducer, comprising the flexible array pressure transducer, a data collection transmission module, a tablet computer, a computer control program, and a motor drive module, wherein the motor drive module is connected with a motor for driving the motor to rotate, and the motor drives the running belt of the running device to rotate. In the invention, stride frequency, stride length, ground-touching time, air time, rearward thrust and other parameters of a runner when in running can be obtained by installing the flexible array pressure transducer on the upper side of the running plate of the running device; acceleration can be calculated by an established relational model of difference of acceleration and the step length between two adjacent steps, the step frequency, the component force of the rearward thrust along the moving directing of the running belt, time for completing two steps (the ground-touching time + the air time), and the weight of the runner; a control command is sent to the motor drive module according to the obtained acceleration; and the motor rotation speed is adjusted; therefore, the speed self-adaption of the running device is realized.

Description

technical field [0001] The invention relates to the field of fitness equipment, in particular to an adaptive speed regulation system of a treadmill based on a flexible array pressure sensor. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, people pay more and more attention to their own health, and the fitness craze is one wave after another, gradually transitioning from exercising in public gyms to building home gyms. Because of its simple form of exercise, the treadmill is often used as the first choice for families. It not only shields the limitations of the venue and environment, but also eliminates many obstacles to exercise. After years of development, a variety of running scene modes and intensity control programs have been accumulated and enriched, and digital functions such as entertainment and Internet calls have been gradually loaded, making it an important carrier for current runn...
