Problems solved by technology

The advantage of this method is that the model classification accuracy is high, the response is fast, and it is less affected by the weather and the environment; It is easy to miss detection when driving away from the middle of the lane. For example, multiple laser range finders are used at the front and rear of each lane. Although the problem of vehicle missed detection can be solved, the cost is too high
Moreover, this method, like the ultrasonic detection method, also needs to be installed on the "gantry frame", which has high auxiliary costs and affects the beauty of the road environment, and is not suitable for the situation where the equipment layout density is high
Therefore, this laser traffic information collection device has many defects, which are limited in practical popularization and application.

Embodiment 1

[0024] Embodiment 1 (see figure 1 , 2 ):

[0025] figure 1 In order to be applied to the situation of a single lane, the present embodiment includes a support positioned at the side of the road, the first and second infrared laser sensors 1, 2, a controller 8, and corresponding to the first and second infrared laser sensors on the road surface. Two parallel first and second reflective tapes 3 and 4 perpendicular to the lane direction; the first and second infrared laser sensors 1 and 2 are fixed on the crossbar 7 on the bracket, and the first and second The distance d between the two infrared laser sensors 1 and 2 is equal to the distance D between the first and second reflective tapes 3 and 4, and the first and second infrared laser sensors 1 and 2 are connected to the controller 8 by cables 9 ;

[0026] The first and second infrared laser sensors 1 and 2 respectively include two or more infrared laser transmitter receivers that are controlled by a controller to emit and ...

Embodiment 2

[0032] Embodiment 2 (see image 3 ):

[0033] image 3 In order to be applied to the situation of two-way two motor vehicle lanes, the difference between embodiment 2 and embodiment 1 is that a pair of first and second infrared laser sensors 1, 2 and their corresponding first and second infrared laser sensors on the other lane are added. , The second reflective tape 3,4.

Embodiment 3

[0034] Embodiment 3 (see Fig. 4):

[0035] Fig. 4 is the situation that is applied to the two-way four-motorway lane that does not have isolation zone in the middle, and implementation 3 is different from embodiment 2 in that a support and two pairs of first and second infrared laser sensors positioned on the support are added, and its installation method is double Side mounted.

Abstract

The invention relates to an infrared laser traffic information collector which comprises a support positioned beside a road, a first infrared laser sensor, a second infrared laser sensor, a controller, a first reflective tape and a second reflective tape; wherein the first infrared laser sensor and the second infrared laser sensor are fixed on a cross bar positioned on the support, and are connected with the controller through cables; The infrared laser traffic information collector has the advantages that the installation is simple, and no portal frame is required to be arranged on the road; the overall cost is low; the influence on the aesthetic measure of the environment is greatly reduced; the collector can be suitable for being distributed in a high density detection station; and the scanning is performed through the light beam of the infrared laser sensors along the width of the traffic lane, so that miss of vehicle detection can not happen.

Description

technical field [0001] The invention relates to an infrared laser traffic information collector, which is suitable for an intelligent traffic system (ITS). It belongs to the technical field of laser technology application. Background technique [0002] With the rapid increase in traffic demand driven by social and economic development, the dense road network cannot meet the needs of traffic growth. In addition to improving roads and expanding the scale of the road network to meet the growing traffic demand, we will use advanced electronics, communications, computers and other high-tech to develop my country's Intelligent Transportation System (ITS), strengthen the management of existing road transportation, and improve the road network. The traffic capacity and the quality of traffic service are very important. [0003] The technologically advanced and practical traffic information collection device is an important part of the Intelligent Transportation System (ITS). At pre...
