GER-DV ground penetrating radar engineering inspection vehicle use the automobile as platform, use the 3D array ground penetrating radar technology as core, merged the 3D super wide array ground penetrating radar, high resolution scanning camera, high definition camera, multiply function laser road tester, high precision GPS fix position and multiply data synchronization and other advance technologies. Realize the detection of road surface, interior and underground defects, and also be able to real time record the up ground routine facilities situation, has advantages at high speed collecting and real time fix position.

Form

● Sub system of 3D array ground penetrating radar or multiply channels ground penetrating radar

The ground penetrating radar sub system formed by 3D array ground penetrating radar system or multiply channels ground penetrating radar system, configured according to actual requirements, include the ground penetrating radar system status, hook structure or antenna drag wheelbarrow, storage and process unit, display unit, distance sensor, fix position system, collecting system and after-processing software. Among, the 3D array ground penetrating radar sub system adopt the super wide band array radar technology to process unified integration design, can process carpet type and completely cover inspection at road structure, harm and damage under road. Can process cut and 3D real time imaging at the data during inspection, can visually display the underground abnormal position, form and damage degree. Can customer made 4~12 channels according to requirements when adopt multiply channels ground penetrating radar sub system, process different frequency antenna assembly according to use requirements, flexible and convenient use.

● High definition wire scan camera sub system

High definition wire scan camera sub system formed by one industry high speed scanning camera and signal collect card. High definition wire scan camera sub system can continuously inspect the cracks above 1mm on the road surface and other harms and get the road damage status. It has the advantages at high definition and quickly collect
speed.

● Multiply functions laser road tester sub system

Multiply functions laser road tester sub system formed with one multiply functions laser road tester, can collect and evaluate the technical index data like the road rut, levelness and road structure depth of each grade road and city road. Can output the parameters like international levelness index IRI, rut depth RUT and road structure depth SMTD which are in accordance with the industry standard, it has the characteristics at automatic, high efficiency and high precision

● High definition camera sub system

High definition camera sub system formed by two high definition cameras, able to real time video and image collect the road surface situation at front and side of road, road administration and road property facilities and road scene, assist back stage fix position.

● High definition GPS sub system

High definition GPS system can realize centimeter level fix position precision under the difference status, can provide the absolute position information for each sub system to realize the precision fix position and search at target and harms.

● Multiply data synchronization sub system

Multiply data synchronization sub system formed with high precision photoelectricity distance measure coder and installation parts, the coder provide working trigger signal to each collect equipment in system, guarantee the synchronization of each data collecting. The system merged the information like high precision GPS position information, radar data channel number, camera shooting serial number, video frame number, laser tester data serial number, the saved various types data at the same inspection position can process accurate synchronization check and processing at the after stage, and repeat the inspection process.

● Collect control sub system

Collect control sub system formed by 2 sets industry control computer, display screen and video compound unit. No.1 industry control computer realized the control data storage of 3D array ground penetrating radar sub system, can real time display the radar image. No.2 industry control computer realized the control and data storage of high definition wire scanning camera sub system, multiply function laser road tester image and high definition camera sub system, can real time display industry camera image, two way high definition video image, laser road tester image. GPS data connect into No.2 industry control computer, this computer can real time display the vehicle driving locus and other geographical information data. 2 sets industry control computer output images information merged to be one complete image through video compound unit and display on the display screen.
