Wireless ground penetrating radar system

Abstract

The invention relates to a wireless ground penetrating radar system, comprising a wireless data collection sub-system and a ground penetrating radar front end sub-system, wherein the wireless data collection sub-system comprises a collection and storage and display unit; the ground penetrating radar front end sub-system comprises a battery, a power supply manostat, an Ethernet controller, an ARM controller, a digital signal processor, an A / D converter, a digital controller, a sequential system, a transmitter, a transmitting antenna, a receiving antenna and a receiver; and the collection and storage and display unit and the Ethernet controller can be connected in a wireless / wired manner. The system is free of restriction of weight and volume as well as limitation of devices in the process of grounding scanning and ground distribution confirmation, and has less power consumption. No movement of the wireless data collection sub-system is needed.

Description

Technical field [0001] The invention relates to a ground penetrating radar (GPR) system with wireless data acquisition and automatic standby functions. Background technique [0002] Ground Penetrating Radar (GPR) system is a kind of geophysical exploration system, mainly used for shallow detection. It is currently a good instrument for underground non-destructive testing including highway structure testing. The areas include cavity inspection, road pavement or underground damage inspection, bridge deck layer positioning, underground pipeline inspection, bridge erosion detection near the river bed caused by bridge erosion, and other areas such as geophysical detection of geological sediments and geological structures, determination of bedrock And the depth of the groundwater level, the structure used to locate underground cultural relics (to prevent accidental damage) before excavation during archaeology, life detection and mine detection, etc. [0003] Traditional ground penetrati...

AI Technical Summary

Problems solved by technology

[0007] However, each part of the above-mentioned traditional GPR system (GPR antenna box 100, GPR control box 120 and data processing unit 130) must move together to complete the scanning of the measured area and then realize the road surface distribution of the measured area

[0008] In addition, the connections between the ground penetrating radar antenna box 100 and the ground penetrating radar control box 120, and between the ground penetrating radar control box 120 and the data processing unit 130 are all wired connections. This wired connection limits the use of the ground penetrating radar system. Convenience and operability, and the wired connection increases the unreliability of the instrument due to frequent plugging and unplugging

[0009] In addition, the ground-penetrating radar control box 120 and the data processing unit 130 are heavy and bulky, so it is difficult to move, which makes it more difficult for the ground-penetrating radar system to complete the scanning operation

[0010] Furthermore, the ground penetrating radar control box 120 and the data processing unit 130 consume a lot of power, and the battery 127 can only provide energy for less than 4 hours, so the ground penetrating radar system will not work properly after 4 hours, and the battery needs to be replaced

[0011] Finally, the components of the ground penetrating radar control box 120 and the data processing unit 130 generally can only use fixed devices, resulting in limitations in use
