Problems solved by technology

At present, the detection of road markings on the market is usually carried out manually. When a large wear of the markings is detected, it is repaired by setting up roadblocks. On the one hand, this method is more labor-intensive, and on the other hand, it is easy to increase the probability of accidents on expressways.

Embodiment 1

[0030] refer to Figure 1-4 , a high-speed marking detection device for intelligent traffic detection, including a car body 1, a plurality of road wheels 4 are arranged at the bottom of the car body 1, and a first drive for driving the road wheels 4 is installed on the car body 1 Institution 2.

[0031] As shown in the figure, the first driving mechanism 2 is composed of a servo motor and a belt transmission mechanism. The servo motor transmits power to the road wheels 4 through the belt transmission mechanism to drive the vehicle body 1 to walk.

[0032] In this embodiment, the car body 1 is provided with a connecting frame 11, and the connecting frame 11 is provided with a hook 12. The setting of the hook 12 plays a role in facilitating the connection with the vehicle, so that marking detection can be realized by hanging on other vehicles and fix.

[0033] The vehicle body 1 is provided with at least one tank body 9 , and when the number of the tank bodies 9 is more than t...

Embodiment 2

[0042] refer to Figure 1-4 , the present embodiment is further provided with an adjustment assembly for driving the horizontal displacement of the marking detection and repair assembly 6 on the car body 1, specifically as follows:

[0043] The adjustment assembly includes a second drive mechanism 3, a light rod 7 and a lead screw 8. The car body 1 is provided with a slot 5 for providing a displacement space for the marking line detection and repair assembly 6. The light rod 7 and the lead screw 8 are all horizontally arranged on the In the slot 5 , the second drive mechanism 3 is in transmission connection with the lead screw 8 , the light rod 7 is slidably connected with the support 61 , and the lead screw 8 is threaded with the support 61 .

[0044]The second driving mechanism 3 is composed of a servo motor and a belt transmission mechanism, and the servo motor transmits power to the lead screw 8 .

[0045] The function of the adjustment assembly is as follows: the second ...

Abstract

The invention discloses a high-speed marking detection device for intelligent traffic detection, and relates to the technical field of municipal traffic detection. The high-speed marking detection device comprises a vehicle body, a plurality of walking wheels are arranged at the bottom end of the vehicle body, and a first driving mechanism used for driving the walking wheels to walk is installed on the vehicle body; at least one tank body is arranged on the vehicle body; and the tank body is connected with a marking detection and repair assembly through a hose. According to the invention, the marking detection assembly is arranged, the laser emitter emits modulated laser, the laser is converted into parallel light rays through the convex lens and irradiates the half-reflecting mirror, and the half-reflecting mirror and the total reflection mirror reflect the light rays to the highway ground for marking detection; and the reflected light is reflected by the total reflection mirror and refracted to the laser receiver by the half reflection mirror, and the high-speed marking line has an obvious reflection coefficient higher than that of a high-speed asphalt or concrete pavement, so that whether the currently detected area is the marking line or the pavement can be accurately judged by detecting the reflection coefficient of the light.

Description

technical field [0001] The invention relates to the technical field of municipal traffic detection, in particular to a high-speed marking detection device for smart traffic detection. Background technique [0002] At present, with the development of smart transportation, research on unmanned vehicles is increasing. However, limited by the development of technology, it will take some time for machines to completely replace humans to complete vehicle driving. Today's smart vehicles often use assisted driving systems to ensure the safety of drivers. For example, the automatic parking assist system, brake assist system, reversing assist system, driving assist system, lane keeping assist system, etc. that can already be seen in high-end models. Among them, the key technology of the lane keeping assist system is the detection of road markings, through which the positional relationship between the vehicle and the road markings can be calculated, and then the driver can be reminded...
