Background technique
For the step counting technology of electric treadmill, traditional approach mainly include the following types: (1) running channel two sides with just
A pair of of far infrared transceiver is installed to mode, number is blocked with signal and carrys out step counting；(2) increase pressure sensing on treadmill
Device, when being run on a treadmill according to people, foot solves to the pressure change of treadmill and walks number of running.Although these method step countings are quasi-
True rate is higher, but since it is desired that installing special sensor, the complexity for being bound to cause running machine structure design increases, together
Shi Zaocheng production cost increases.Patent No. CN201420085472.7 " is used for the intelligent step counting system of electric treadmill ", lead to
Current of electric when crossing closed-loop Hall current sensor acquisition treadmill work, comparison electric current is compared with setting value, if adopted
Collect numerical value and be more than or equal to setting value, step number adds 1；Less than setting value, step number is constant.This scheme seems to can be realized electricity from principle
Dynamic treadmill step counting, but since people in electric treadmill when moving, speed difference, bodyweight difference, to the peak value shadow of electric current
Sound is very big, and in addition in completely walking, running, the variation of electric current is also not the sine wave of a standard, in fact it could happen that two are not
Same peak value, so simple go to calculate step number by a fixed current threshold, error is larger；In addition closed loop Hall current passes
Sensor price is higher, increases the production cost of treadmill.
Therefore existing electric treadmill step counting scheme needs to improve.
