Embodiment 1

[0028] The automatic monitoring system of the high-speed moving vehicle of the present invention uses the laser sensor and the radar speedometer to collect basic data synchronously, and transmits the data to the data processor, and then uses the data processor to describe the shape of the vehicle by constructing a mathematical model and designing an algorithm feature, determine its lane position, and perform vehicle speed feedback and data statistics.

Embodiment 2

[0030] The automatic monitoring system of the high-speed moving vehicle of the present invention, as figure 1 As shown, the laser sensor is installed on the roadside of the road to be tested to scan the position of each point on the vehicle, and its installation height is h(h≥0) , the probe faces the road surface, the installation position of the probe is parallel to the cross-section of the road, and the scanning angle of the laser sensor is , install a radar speedometer on each lane, each radar speedometer is perpendicular to the intersection line between the laser sensor scanning surface and the road surface, and the installation height of each radar speedometer is the same, each radar speedometer to the laser sensor scanning surface and the road surface The distances of the intersecting lines are equal, the irradiation direction of the radar speedometer must face the laser sensor, and the installation angle of each radar speedometer is the same.

Embodiment 3

[0032] The hardware configuration of the automatic monitoring system of the high-speed moving vehicle of the present invention:

[0033] like figure 1 As shown, the gantry IGH and the gantry JFE are parallel to each other, perpendicular to the lane separation line, and are located on both sides of the expressway. The three points of J are installed at the nearest edge of the nearest lane and keep a certain distance, and the four points of E, F, G, and H are respectively installed with a radar measuring instrument. The radar speed measuring instrument is installed on the front of the front of the vehicle. Adjust the up, down, left, and right angles of the radar speedometer F, so that the most effective road speed measurement area is F S , adjust the other three radar speedometers in the same way, so that the most effective speed measurement areas of the three radar speedometers are G S、 h S、 E. S Four elliptical areas G S、 h S、 E. S、 f S The front, rear, left, and righ...

Abstract

The invention discloses an automatic monitoring system of a vehicle with high-speed movement, and relates to a vehicle monitoring system. According to the automatic monitoring system of the vehicle, basic data is acquired in a synchronous manner by employing a laser sensor and a radar speed detector, the data is transmitted to a data processor, a mathematical model is established, an algorithm is designed, appearance characteristics of the vehicle are described by employing the data processor, the position of a lane at which the vehicle is located is determined, and speed feedback and data statistics of the vehicle are performed. According to the automatic monitoring system of the vehicle with high-speed movement, the mathematical model is established and the algorithm is designed by employing the data synchronously obtained by the laser sensor and the radar speed detector to restore the appearance of the vehicle, and the lane at which the moving vehicle is located and speed information can be fed back; and by employing matched hardware facilities, the road condition of the highway can be truly restored, the operation condition of the vehicle can be monitored, and the geometric characteristic and the corresponding speed of each vehicle in movement can be extracted.

Description

technical field [0001] The invention relates to a vehicle monitoring system, in particular to an automatic monitoring system for a high-speed moving vehicle. Background technique [0002] Since the reform and opening up, my country's expressway construction has developed by leaps and bounds. By the end of 2015, the total mileage of my country's expressway has reached 120,000 kilometers, which plays an increasingly important role in my country's economic development. However, on expressways or ordinary roads, the monitoring system for high-speed vehicles is extremely lacking. On most highways, "radar speedometers" are only installed to feed back and monitor the speed of high-speed vehicles, but other information about the vehicle, such as the geometric characteristics of the vehicle, cannot be known. [0003] At present, there are mainly two types of methods for extracting geometric feature parameters of vehicles: one is to extract geometric parameters of vehicles based on ...
