Description
?
Technical field
The present invention relates to quality detecting device field, ground, particularly, relate to the loosening pick-up unit of a kind of geology based on geological radar.
Background technology
Geology is loosening is ubiquitous actual physics mechanical state in underground works, larger to the stability influence of underground works.Geology is loosening is also the omen of disaster simultaneously, for example: landslide, landslide etc., are also the judgment criteria of underground construction safety coefficient.When the loosening situation of geology is detected, when disaster being predicted or the security of underground construction is passed judgment on, the general boring method that adopts, in different geographic position, arrange some groups of borings, every group of two borings, and the degree of depth in hole is greater than the degree of depth of relaxation zone, also need to injected water in hole.There are a lot of problems in it, water pipe need to be provided in operating process, and workload is large, and adopt water as the coupling medium of sonic probe and hole wall, and the pressure of water, flow etc. are all had to higher requirement, practical operation difficulty.
Summary of the invention
Technical matters to be solved by this invention is to provide the loosening pick-up unit of a kind of geology based on geological radar, and it is simple in structure, and simple to operate, and accuracy of detection is high.
The present invention addresses the above problem adopted technical scheme:
The loosening pick-up unit of geology based on geological radar, comprise antenna and master controller, described antenna is connected with geological radar work schedule control circuit by signal receiving circuit, described geological radar work schedule control circuit is connected with antenna by signal transmission circuit, described geological radar work schedule control circuit is connected on master controller, described signal receiving circuit and geological radar work schedule control circuit are all connected on prime amplifier able to programme, and described prime amplifier able to programme is connected on master controller by AD converter.In the present invention, adopt geological radar to survey the loosening situation of geology, its resolution is high, accurate positioning, quick and real-time, does not need to add the assistants such as water, convenient operation.In use, master controller is as control core, control signal transmission antennas transmit electromagnetic wave, electromagnetic wave is propagated in stratum, run into and there is medium electrical, physical difference, just can form reflecting interface and reflect, reflection of electromagnetic wave is gone back to ground and through signal receiving circuit, prime amplifier able to programme and AD converter, is returned to master controller by antenna reception, master controller according to electromagnetic wave propagation time, waveform character to determine position, geometrical body of stratum medium etc.Center of antenna frequency is multi-frequency.
As preferably, on described master controller, be connected with display device, external memorizer and touch-screen input equipment.Utilize display device to show the structure on stratum, data, be convenient to personnel's direct observation.
Further, described display device is liquid crystal display.
As preferably, described master controller is LPC2013, and it is the ARM microcontroller of 32, and its processing speed is fast, can improve whole performance.
To sum up, the invention has the beneficial effects as follows:
1, of the present invention simple in structure, do not need to add in use water, it is simple to operate.
2, the present invention utilizes geological radar to survey the loosening layer of geology, and its accuracy of detection is high.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present invention.
