Sensor outfan is electrically connected with mcu controller.
Further, also include external program memory, described external program memory is electrically connected with mcu controller.
Further, also include display lamp, described display lamp is electrically connected with mcu controller.
A kind of method measuring the treadmill gradient based on six axle acceleration sensors, comprises the following steps:
The first step, measures acceleration of gravity and the angular velocity of three coordinate directions of x, y, z using six axle acceleration sensors；
Second step, the acceleration of gravity of three coordinate directions of x, y, z and angular velocity is passed through six axle acceleration sensors built-in
Dmp is converted to quaternary number (q0, q1, q2, q3)；
3rd step, this quaternary number (q0, q1, q2, q3) is calculated angle of pitch pitch, pitch=through muc controller
asin(-2*q1*q3+2*q0*q2)*57.3.
By adopting preceding solution, the invention has the beneficial effects as follows: the present invention is a kind of to be based on six axle acceleration sensors
The device and method of the measurement treadmill gradient, is accelerated using the gravity that six axle acceleration sensors detect three coordinate directions of x, y, z
Degree and angular velocity, the acceleration of gravity of three coordinate directions of x, y, z and angular velocity pass through the built-in dmp of six axle acceleration sensors simultaneously
Pass to mcu controller after conversion, the angle of pitch is calculated by muc controller.Further, mcu controller electrical connection journey
Sequence memorizer, extends muc controller memory capacity；Further, the working condition of this device is observed by display lamp.The present invention
There is easy for installation, with low cost, intelligent measure value of slope.
