Description

Highway vehicle overrun detecting system

Technical Field

The utility model relates to a system for checking whether each index of a passing vehicle exceeds the road management regulation or not at an expressway entrance.

Background

With the continuous rising of the reserved quantity of vehicles, the number, types and increasing quantity of vehicles running on the highway are increased, and in order to ensure the running safety, prolong the service life of the highway and accurately collect the toll of the highway according to the regulations, an over-limit detection system for vehicles on the highway is urgently needed, the overall dimension of the passing vehicles is accurately detected in real time, and the vehicles with ultrahigh and over-overall dimensions are timely found and required to run away from the highway; meanwhile, the system also can accurately identify the information such as the vehicle type, the axle type, the number of axles, the weight and the like of the passing vehicle so as to accurately calculate the highway toll.

At present, an overrun rod is installed at an entrance of a highway, the passing of an ultrahigh truck is prevented in a mechanical mode, once the overrun rod is damaged by collision, maintenance is needed, and the maintenance cost is high. A land scale is arranged at the entrance of the highway truck to weigh the weight of the truck, and a toll collector visually identifies the truck type and calculates the cost. The disadvantages of this charging approach are: some truck owners modify the truck privately in order to increase the load capacity, and toll collectors cannot accurately identify the truck type, the axle type and the axle number, so that the condition of manual misjudgment exists, and the charging is inaccurate. At present, some domestic expressways are provided with vehicle overall dimension identification systems, which can identify the overall dimension of vehicles, but cannot identify the types, axle types and axle numbers of the vehicles.

FIG. 1 is a schematic diagram of the system for detecting vehicle overrun on a highway.

Detailed Description

The structure and features of the present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that various modifications can be made to the embodiments disclosed herein, and therefore, the embodiments disclosed in the specification should not be construed as limiting the present invention, but merely as exemplifications of embodiments thereof, which are intended to make the features of the present invention obvious.

As shown in FIG. 1, the highway vehicle overrun detection system disclosed by the utility model is arranged at an entrance of a highway and is arranged along the driving direction of a vehicle. The system comprises three laser scanners, a dynamic motor scale and a control cabinet.

The first laser scanner 1 is installed at a position of about 25 meters in front of the tollbooth 2, left or right of the lane, and 0.8 meters from the ground. The method is mainly used for collecting the axle information of the passing vehicle, such as the axle type and the axle number of the vehicle, so as to judge whether the passing vehicle is a passenger car or a truck.

A second laser scanner 4 is fixed on the other side of the lane at a position 6 m high, flush with the fixed first laser scanner 1, the second laser scanner 4 and the first laser scanner 1 being located on the same vertical plane. The second laser scanner 4 is matched with the first laser scanner 1 to collect the height and the width of the passing vehicle; on one hand, whether the passing vehicle is ultrahigh is judged through the collected information, and on the other hand, the type of the passing vehicle, namely a passenger car or a truck, is further judged through the collected overall dimension of the passing vehicle.

Since the second laser scanner is mounted in a high position, looking down the entire passing vehicle, it has the further function of signaling the start and end of weighing.

Flush with first laser scanner 1, along the vehicle advancing direction, on the subaerial in lane, lay a dynamic truck scale 5, dynamic truck scale 5's upper surface and ground smooth joint, below the dynamic truck scale, four corners respectively install a weighing sensor for gather weight signal. The dynamic truck scale 5 is used for weighing the passing vehicle and collecting the weight information of the passing vehicle.

An L-shaped mounting frame 6 having a height of 6 m is mounted and fixed to the left or right side of the lane at a distance of 25 m from the first laser scanner 1 in the advancing direction, extends to the center of the lane, and a third laser scanner 7 is fixed above the center of the lane. The third laser scanner 7 collects length information of the passing vehicle in cooperation with the second laser scanner 4,

the utility model also comprises a control cabinet 8 which comprises a power switch, a computer and a display screen, wherein the data information acquired by the first, second and third laser scanners and the dynamic motor scale is transmitted to the computer in a wired or wireless transmission mode, and the computer uploads all the acquired information of passing vehicles, including information such as vehicle types, axle numbers, overall dimensions and total weight of the vehicles, to the upper computer.

In the present embodiment, a vertical pole 1 m high is erected on the left or right side of the lane, the first laser scanner 1 is fixed at a position 0.8 m from the ground, a vertical pole 6 m high is erected on the other side of the lane, and the second laser scanner 4 is fixed at a position 6 m from the ground. Alternatively, a 6-meter high portal frame 3 is erected on both sides of the lane, the first laser scanner 1 is fixed at a position of a column on one side of the portal frame, which is 0.8 meter away from the ground, and the second laser scanner 4 is fixed at a position of a column on the other side of the portal frame, which is 6 meters away from the ground.

When a running vehicle enters the entrance of the expressway, since the first laser scanner 1 is fixedly installed at a position 0.8 m away from the ground and facing the wheel area of the vehicle, the first laser scanner 1 collects axle information of the passing vehicle such as the axle type, the number of axles, the inter-axle distance, the axle length, and the side information of the side of the vehicle, thereby judging the type of the vehicle, i.e., the passenger and cargo information and the axle type and number information of the passing vehicle. At the same time, the second laser scanner 4 starts scanning information of the top of the vehicle and the side of the other side of the vehicle, and measures information of the height and width of the vehicle in cooperation with the first laser scanner 1.

Since the second laser scanner is installed at a higher position, the whole vehicle can be viewed from above, and therefore, when the front and rear wheels of the passing vehicle are completely rolled on the dynamic automobile scale 5, the second laser scanner 4 sends a weighing instruction; when the front wheel of the vehicle drives away from the dynamic truck scale, the second laser scanner sends a weighing stopping instruction. As the vehicle passes the dynamic vehicle scale 5, the load cell beneath it transmits a measured weight signal to the computer 8.

After the vehicle leaves the scanning area of the second laser scanner, the third laser scanner 3 obtains the length information of the vehicle according to the relative position information of the vehicle head, and further verifies the vehicle type of the passing vehicle.

All information and data collected by the laser scanners and the dynamic motor scale are uploaded to a computer in the control cabinet in a wired or wireless transmission mode, and the computer sends a complete data packet to an upper computer.

Finally, it should be noted that: the above-mentioned embodiments are only used for illustrating the technical solution of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
