Problems solved by technology

[0007] In the process of using vehicle-mounted radar to detect underground road diseases, it is necessary to mark the points found in the detection for re-examination, disposal and maintenance. However, the vehicle-mounted inspection speed is fast, and the current abnormal point marking mainly relies on GNSS to mark coordinates, but the vehicle During the movement, the GNSS signal is often unstable, which leads to large positioning deviation of coordinate points, which causes great inconvenience to the review and disposal of diseased points

Embodiment 1

[0040] refer to Figure 1-4 , a device for automatically marking abnormal points in the vehicle-mounted radar detection process, comprising a tractor 1, the front end of the tractor 1 is provided with a physical point marking device 3, and the physical point marking device 3 communicates with the device through an I / O card 5 The monitoring terminal 4 inside the tractor 1 is connected, the rear end of the tractor 1 is provided with a radar support 2, and the lower end of the radar support 2 is provided with a radar 9, and the radar 9 is connected with the monitoring terminal 4 for real-time detection by the radar 9 For road disease conditions, the monitoring terminal 4 monitors the road information acquired by the radar 9 in real time, and makes spraying instructions for abnormal data.

[0041]Further, in this embodiment, a power supply 6 is also included, and the power supply 6 is respectively connected to the physical point marking device 3 , the monitoring terminal 4 , the I...

Embodiment 2

[0058] Other structures are with embodiment 1, and the difference with embodiment 1 is:

[0059] In this embodiment, the physical point marking device 3 includes an electric telescopic device 12 and a painting device 11, the electric telescopic device 12 is connected with the painting device 11 through a spring 13, and rubber clamp pads are arranged around the painting device 11 14. It can prevent the physical point marking device 3 from rotating and loosening, so as to ensure the spraying effect. When the physical point marking device 3 is energized, the electric telescopic device 12 can be extended, and the paint spraying device 11 is pressed to spray to form a physical mark; when the physical point marking device 3 is powered off, the spring 13 can make the electric telescopic device 12 reset quickly, so that it can be retracted freely , Avoid overspraying. The paint spraying device 11 can be equipped with two or more sets of spray paints of different colors, which can rea...

Abstract

The invention discloses an abnormal point location automatic marking device and method in a vehicle-mounted radar detection process, the device comprises a tractor (1), the front end of the tractor (1) is provided with a physical point marking device (3), the physical point marking device (3) is connected with a monitoring terminal (4) arranged in the tractor (1) through an I / O card (5), the rear end of the tractor (1) is provided with a radar support (2), and a radar (9) is arranged at the lower end of the radar support (2) and connected with the monitoring terminal (4). Automatic marking can be achieved, and normal work of technicians is not affected; and the marking precision is high; and a spring (13) is arranged in the physical point marking device (3), so that the electric telescopic device (12) can be helped to quickly reset, free folding and unfolding are realized, and excessive spraying is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle radar, in particular to an automatic marking device and method for abnormal points in the detection process of vehicle radar. Background technique [0002] In the daily maintenance and management of roads after they are put into use, problems such as damage, sags, cracks, and leveling on the road surface can usually be found in time, but the hidden disasters existing in the road, such as holes, water accumulation, and detachment under the road surface Empty, loose foundation, etc., but there is no effective detection method. [0003] With seasonal rainfall, winter ice melting in summer, thermal expansion and cold contraction, construction damage and accumulated stamping, it is often easy to cause major traffic accidents. In recent years, with the rapid expansion of urban scale, a large amount of underground space has been developed, the construction and operation of subways, viaducts, tunnels, an...
