Full-automatic inertial sensing pavement evenness detection system and detection method

Abstract

A full-automatic inertial sensing pavement evenness detection system comprises a sensing unit, which comprises an accelerometer, a gyroscope and a temperature sensor; the accelerometer is an inertial sensor; a three-axis angular rate sensor of the inertial sensor is used for measuring and outputting the angular rates of motion in two directions to a peripheral processing circuit; and the processing circuit receives the measuring results outputted by a three-axis acceleration sensor and the three-axis angular rate sensor, and acquires the pavement evenness information of each measured point by way of operation as a probe passes through a measured pavement. By adopting the miniature solid-state vibratory gyroscope and the MEMS (Micro-electromechanical System) accelerometer as core measuring devices, the invention effectively reduces the size of the measuring system, and the system can resist shock vibration, can be adapted to various pavement evenness measurement environments, can carry out full-automatic detection, and cannot be affected by outside electric and magnetic fields.

Description

technical field [0001] The invention relates to a road surface smoothness measurement technology, in particular to a fully automatic inertial sensing device for detecting road surface smoothness and a detection method thereof. Background technique [0002] As a country with a large population, China is also a country with a large transportation network. By the end of 2010, the total mileage of national highways was close to 4 million kilometers. With the increase of highway mileage, how to effectively detect the huge highway network has become a focus of social attention. As we all know, damaged municipal roads have obvious damage to vehicles, which will not only reduce the service life of vehicles and increase maintenance costs; moreover, uneven municipal roads also bring safety hazards to citizens' travel and drivers' driving. See the attached table for the criteria for judging the smoothness of the road surface. Therefore, how to adopt a road detection method to effecti...
