Road surface integrated sensor for networked traffic management

Abstract

The invention relates to the technical field of passage traffic equipment, and further discloses a road surface integrated sensor for networked traffic management. The sensor comprises two sets of embedded shells arranged on a road, the two sets of embedded shells are located on the two sides of the middle line of the road, connecting rod structures for converting vertical force into transverse force in an equal proportion mode are movably installed in the embedded shells, and each connecting rod structure is at least composed of 10-16 connecting rod pieces. In the road surface integrated sensor for networked traffic management, under the action of the translation roller and the connecting lever, on one hand, the pressure at any position is converted into transverse force in the same form,data errors caused by deformation of the metal plate are eliminated, and on the other hand, the pressure of the wheels is reduced to a measurable change interval, continuous current changes in the passing process of the automobile are measured, continuous change characteristics are obtained, the four wheels are detected respectively, or four sets of data characteristics are obtained, and more automobile information can be obtained by analyzing the four sets of wheel data.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to a road surface integrated sensor for networking traffic management. Background technique [0002] Such as Figure 6 As shown, it is a common traffic detection sensor, the upper and lower copper poles, hard metal plate and pressure-sensitive sheet in the middle, when the wheel rolls on the hard metal plate, the resistance of the pressure-sensitive sheet changes, and it is installed on the road On the other hand, the lane occupancy rate, vehicle speed and axle distance can be monitored more accurately. [0003] This type of sensor collects vehicle information when the wheel runs over the sensor. In order to ensure that the wheel can be rolled over the sensor when the vehicle passes by, and at the same time reduce damage to the road surface during installation, it is usually designed as a long strip, and the vehicle is rolled over when passing The position can not be uniform, ...

Problems solved by technology

[0003] This type of sensor collects vehicle information when the wheel runs over the sensor. In order to ensure that the wheel can be rolled over the sensor when the vehicle passes by, and at the same time reduce damage to the road surface during installation, it is usually designed as a long strip, and the vehicle is rolled over when passing The position can not be uniform, the force position of the hard metal plate, the small deformation caused by the force will also have obvious differences, and finally, the pressure transmitted to the pole piece will also change, therefore, restricting the accuracy of this type of sensor improve

[0004] Furthermore, because the position of the wheel running over the sensor is different, it will interfere with the detection results, and the reference value of the obtained data is low. In fact, this type of device is mostly used to detect the passing of vehicles, trigger speed radar, and take pictures of running red lights. Other detection equipment, its function Sex still has a lot of room for improvement
