Abstract

The invention relates to a measuring technology, in particular to a method for detecting tumblingof an object and a measuring device for implementing the method. The method for detecting the tumbling of the object by the adoption of an accelerometer and a gyroscope which are fixed on an object to be detected includes the following steps: according to an accelerated velocity obtained through the measurement of the accelerometer, determining whether or not a side tumbling degree of the object to be detected is out of a normal range; if the side tumbling degree of the object to be detected is out of the normal range, determining whether or not the object to be detected tumbles according to an angular velocity obtained through the measurement of the gyroscope; if it is determined that the object to be detected tumbles, outputting a signal for indicating that the object to be detected tumbles.

Description

technical field [0001] The invention relates to measurement technology, in particular to a method for detecting object rollover and a measurement device for realizing the method. Background technique [0002] In many aspects, such as the inertial measurement system of the space vehicle, the tilt measurement of the vehicle and ship, the balance attitude detection of the robot and the determination of the extension of the mechanical arm, it is necessary to measure the attitude parameters such as the tilt and direction of the object. [0003] With the development of Micro-Electro-Mechanical Systems (MEMS) technology, the conditions for applying MEMS sensors to attitude detection systems are becoming more and more mature. Acceleration sensors and gyroscopes based on MEMS technology have the advantages of strong impact resistance, high reliability, long life and low cost, and are suitable inertial sensors for building attitude detection systems. The measurement system composed o...
