Problems solved by technology

At present, there are two main types of pipeline attitude detection systems. One is to use a three-axis gyroscope and a three-axis accelerometer to form an inertial measurement system to measure the attitude information of the pipeline detector. However, this system is large in size and high in power consumption, which is not conducive to the pipeline detector. task requirements; one system is an attitude detection system composed of three-axis gravity sensors, which uses three-axis gravity information to calculate the attitude, but this attitude detection system fails when the detector is close to the vertical angle, which cannot meet the pipeline detection task need

Abstract

The invention provides a gesture detection system of a pipeline detector. The gesture detection system comprises a gyroscope, an inclined angle sensor set, a signal processor and an installation structure, wherein the gyroscope, the inclined angle sensor set and the signal processor are mounted on the installation structure; the gyroscope is used for measuring an angular velocity of the detector and transmitting the angular velocity to the signal processor; the inclined angle sensor set is used for measuring a gravity acceleration of the detector and transmitting the gravity acceleration to the signal processor; and the signal processor comprises a detector gesture detection device and comprises a gesture preparation combination resolving module and a detector operation combination resolving module. According to the gesture detection system of the pipeline detector, gyro information and three axial gravity information are fused so as to resolve the gesture information of the pipeline detector; the system is small in volume and low in power consumption, and is suitable for various track requirements of the pipeline detector; and the detection method does not need to be combined with other devices to use and can guarantee the gesture precision in a long-time detection task.

Description

technical field [0001] The invention relates to a posture detection system of a pipeline detector, which belongs to the technical field of pipeline detection. Background technique [0002] The attitude detection device of the pipeline detector provides the angular position information of the pipeline defect for the detector, which is indispensable detection information for pipeline defect detection. At present, there are two main types of pipeline attitude detection systems. One is to use a three-axis gyroscope and a three-axis accelerometer to form an inertial measurement system to measure the attitude information of the pipeline detector. However, this system is large in size and high in power consumption, which is not conducive to the pipeline detector. task requirements; one system is an attitude detection system composed of three-axis gravity sensors, which uses three-axis gravity information to calculate the attitude, but this attitude detection system fails when the d...
