Abstract

The invention relates to measurement technology, in particular to a method for detecting object rollover and a measurement device for realizing the method. According to an embodiment of the present invention, the method for detecting rollover of an object by using an accelerometer and a gyroscope fixed on the object to be measured includes the following steps: determining whether the rollover degree of the object to be measured exceeds a normal range according to the acceleration measured by the accelerometer; If it exceeds the normal range, it is determined whether the object under test rolls over according to the angular velocity measured by the gyroscope; and if it is determined that the object rolls over, a signal indicating that the object under test rolls over is output.

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...
