Runner identity identification and step counting method based on running machine

Abstract

The invention provides a runner identity identification and step counting method based on a running machine. The runner identity identification and step counting method comprises the steps of: 1, collecting current values of the running machine at different speeds separately; 2, transmitting the current values to a database of a cloud server separately by means of the running machine; 3, extracting features of the current values by means of the cloud server separately, and carrying out normalization processing on the features; 4, training the cloud server based on the normalized features to obtain classification parameters; 5, and transmitting the parameters to a controller of the running machine by means of the cloud server, identifying the identity of a runner according to the classification parameters by means of the controller, and counting a number of steps by means of the controller. The runner identity identification and step counting method improves the precision of runner identity identification and step counting, enhances the function of the running machine, and is economical and practical.

Description

technical field [0001] The present invention relates to a treadmill-based runner identity recognition and step counting method, more specifically, by processing the signal of the motor working current of the treadmill, using machine learning technology to intelligently identify the identity of the runner, and A method for realizing running step counting belongs to the technical field of fitness equipment. Background technique [0002] Regarding the pedometer technology of electric treadmills, the traditional methods mainly include the following: (1) install a pair of infrared transceivers in a facing manner on both sides of the running channel, and count the steps by the number of times the signal is blocked; (2) A pressure sensor is added to the treadmill, and according to the pressure change of the foot on the treadmill when the person is running on the treadmill, the number of walking and running can be calculated. This method requires special sensors to be installed, th...

Problems solved by technology

However, due to the different speeds and weights of runners, even the tightness of the treadmill belt has a great influence on the peak value of the current; secondly, in the complete walking and running, the change of the current is not a standard sine wave, and may appear Two different peak values, so simply use a fixed current threshold to calculate the number of steps. Obviously, it is impossible to get accurate step counting in practical applications; again, if the treadmill is not a person, but an object, then this method It is impossible to distinguish whether it is a person or not, and it will misjudge the heavy object as a person running on it; finally, the current acquisition accuracy of the closed-loop Hall current sensor is low, and this solution cannot achieve accurate step counting

Moreover, the price of the closed-loop Hall current sensor is relatively high, which increases the production cost of the treadmill.

[0003] There is no similar technology and application for identifying the identity of the runner by running on the treadmill. However, with the development of the Internet of Things, Internet of Things treadmills are becoming more and more common. If the identity of the runner can be automatically identified, it will automatically provide Targeted exercise guidance, which will make the treadmill more intelligent and practical, so the current method and technology of electric treadmill pedometers still need to be improved and perfected.
