Remote pavement construction diagnosis system and method based on infrared thermal image of third-generation (3G) network

Abstract

The invention discloses a remote pavement construction diagnosis system and method based on an infrared thermal image of a third-generation (3G) network. The system comprises an infrared thermal image acquisition system and an infrared thermal image quality inspection center which are in communication connection with each other through a 3G wireless communication network, wherein the infrared thermal image acquisition system comprises an advanced reduced instruction set computer (RISC) machine (ARM) embedded system, an infrared thermal imager which is connected to the ARM embedded system, a distance measuring device and a 3G wireless communication module; the infrared thermal image quality inspection center comprises a 3G wireless network card and a data processor; the infrared thermal image acquisition system and the infrared thermal image quality inspection center are in communication connection with each other through the 3G wireless communication module and the 3G wireless network card. Through an advanced 3G network transmission technology, the remote wireless communication of a control signal and the real-time transmission, recording and analysis of an infrared image and temperature data between the infrared thermal image acquisition system and the infrared thermal image quality inspection center are easily realized.

Description

technical field [0001] The invention relates to the technology in the field of automatic control, in particular to a remote road construction diagnosis system and method based on 3G network infrared thermal images. Background technique [0002] With the substantial increase in the mileage of high-grade highways and expressways and the increase in traffic volume year by year, accurate and rapid detection of road damage without disturbing traffic has become an urgent need for road maintenance management. The main damage of asphalt pavement can be divided into surface damage and deformation. The scope and degree of these two types of damage are usually the basis for asphalt pavement maintenance. The pavement testing equipment that has come out or is in the research stage also mainly detects these two types of damage . Among them, non-destructive testing based on image processing technology is an important direction of research in this field, but the current technical level is ...

Problems solved by technology

In contrast, laser rotating mirror detection is rarely used in practice due to its complex structure and high cost; optical interference detection is not suitable for detection in dynamic environments because it is extremely sensitive to vibration; the presence of laser structured light can only be detected at night or The problem of low detection accuracy due to vibration

[0004] In view of the above reasons, although a variety of automatic pavement detection equipment based on image processing has come out, its application in actual production practice is still very limited, and there is still a lot of room for research in this field.
