Problems solved by technology

[0006] 1) The coupling noise between the geophone and the ground is large during motion, which will affect the quality of data collection;
[0007] 2) In addition, due to the short ground coupling time of the geophone, the data recording time is rushed, which will affect the seismic exploration effect
Although this method of manually or mechanically controlling the vibrator vehicle is stable and reliable, it is very inconvenient to operate; especially when the detection mileage is long, this periodic operation is easy to make the operator tired, and the stroke position of the positioning and detection system It is also difficult to accurately determine

Embodiment 1

[0093] In this embodiment, the vehicle body of the probe vehicle is an electric vehicle with its own electric driving power. Such as Figure 1-Figure 5 Shown:

[0094] The detection car used for roadbed hidden danger detection in the present embodiment comprises: car body 1, control system 2, seismograph 3, seismic source, seismic sensor 6 and travel acquisition device 7, and described seismic source comprises impact device 4 and seismic source motor 5 and A trigger sensing device 8 attached to the impact device 4, wherein:

[0095] Described control system 2, seismograph 3 and percussion device 4 and seismic source motor 5 are located in the car body 1, and described control system 2 is connected with seismograph 3 and percussion device 4 of seismic source and seismic source motor 5 and this trigger induction respectively by line. The device 8 is connected; the trigger sensing device 8 is connected with the seismograph 3 through a signal transmission line;

Embodiment 2

[0118] The difference between this embodiment and embodiment 1 is:

[0119] The magnetoelectric sensor of the trigger induction device 8 arranged on the seismic source is omitted;

[0120] In step S3, the seismograph is activated by the signal given when the impact device hits the ground, starts to collect data from the seismic sensor, and at the same time sends a signal to the control system to use this as a time reference point, and measures the seismograph to start collecting data. The length of time t, after the time t is completed, the seismograph stops collecting data, the output port of the control system outputs the electronic brake off signal and the driving switch start signal, and the car body moves.

Embodiment 3

[0122] The difference between this embodiment and embodiment 1 is:

[0123] 1) As shown in Figure 6, the car body 1 of the probe car in this embodiment is a towed car body with other electric vehicles as the tractor, and a four-wheeled electric scooter for the elderly with a traction power of 1000 watts is specifically selected as the tractor , by traction lock 10 between the tractor and the car body without walking power, carrying the seismic source and the seismograph, the rigidity is dragged and hung on the bumper behind the tractor.

[0124] 2) In this embodiment, the probe vehicle control system 2 adopts a notebook combined with an FPGA with multi-channel digital I / O ports as the control system hardware, keeps the original control system on the tractor vehicle, and incorporates the probe vehicle control system 2 into the traction vehicle. The vehicle body walking power control system 9 of the car.

[0125] 3) The detection car in embodiment 1 only has a state of subgrade...

Abstract

The invention relates to a probe vehicle for hidden roadbed danger detection and a detection method thereof. The probe vehicle is composed of a vehicle body, a control system, a seismometer, a seismic focus, a seismic sensor, and a stroke collection device. The control system consists of a CPU, an input port, and an output port, wherein the input port and the output port are connected with the CPU; the input port is connected with the stroke collection device; and the output port is connected with the seismometer, a seismic focus, and a brake system of the vehicle body. The seismic focus includes an impact device and a focus motor. According to the invention, travelling-stopping-travelling-stopping cyclic work can be completed automatically; and instability and inaccuracy due to a manual or mechanical way for controlling a vibrator vehicle for working can be avoided. Two processes of travelling and stopping for waiting can be completed within one travelling-stopping working period, the travelling-stopping motion and seismic data collection motion of the probe vehicle can be carried out simultaneously, and the seismic focus power storage can be completed simultaneously, so that the working efficiency of the probe vehicle can be improved. In addition, the invention also provides a detection method of the probe vehicle.

Description

technical field [0001] The invention relates to a detection vehicle for detecting roadbed hidden dangers and a detection method thereof, and belongs to the technical field of continuous seismic exploration data acquisition of roads, railways or foundations. Background technique [0002] The hidden danger detection of highways, high-speed railway foundations and building foundations, especially the detection and early warning of hidden dangers in highways and urban roads, is related to the safety of people's lives and property and even social stability. In the non-destructive hidden danger detection method, the seismic exploration depth is relatively large, and it can provide elastic wave parameters and geotechnical engineering mechanical parameters. Therefore, compared with other detection methods, it has obvious advantages in judging the existence of hidden dangers and the reliability of positioning and qualitative. [0003] In seismic exploration, seismic waves are excited...
