Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a structure of a vehicle,

The present invention relates to a structure and a structure positioning system for a vehicle detector capable of adjusting a detection position, and more particularly, to a vehicle detector capable of adjusting a detection position of a vehicle detector attached to a structure, Structure and structure positioning system.

Traffic survey for traffic data collection is necessary for planning, designing, construction and maintenance of traffic facilities. In recent years, such traffic surveys have been carried out in the form of manpower. However, in recent years, due to the expansion of the Intelligent Transportation Systems (ITS) business, a vehicle detector (see FIG. 1) installed on the road and collecting traffic information in real time .

Vehicle detectors are largely classified into buried type and non buried type. A buried type vehicle detector is a method of detecting a vehicle running on a road by embedding a vehicle detection sensor (a piezo sensor, a loop center, etc.) A buried vehicle detector uses a non-contact type sensor such as a video or a laser.

Among them, the non-buried vehicle detector is largely composed of an information collecting unit, a control unit, and a structure in which a camera is mounted. First, the information collection unit is a collection of traffic information, which consists of cameras and peripheral devices. And takes a picture of the vehicle traveling by using the camera and transmits it to the control unit. Such an information collecting unit is positioned in the air of a height of several meters in height because it needs to shoot and recognize the vehicle to be driven as accurately as possible. Second, the control unit processes the image information transmitted from the collecting unit (camera) to calculate the traffic parameters such as traffic volume, speed, and occupancy rate, and transmits the calculated traffic parameters to the traffic center and the like. The information collecting unit is generally configured such that an information processing apparatus, a power supply apparatus, a heat treatment apparatus, and the like are placed in a steel-made enclosure. Third, the structure is composed of a pole (pole) and an arm (arm), which is necessary for structurally supporting the information collector as it is located in the air. A typical vehicle detector, such as an image detector, an AVI, a CCTV, a VMS, a traffic signal, etc., includes an information collecting unit, a control unit, and a structure unit.

The shape of the structure of the vehicle detector is determined by considering the traffic characteristics (traffic volume, lane number, lane width, road geometry, surrounding environment, etc.) . The construction of the structure digs the ground several meters deep, and after the structure is buried, the concrete is fixed by the concrete. The installation direction of the information collecting part and the arm length determined according to the shape of the structure determine the detection position, which has a decisive influence on the accuracy of the collected traffic information.

Once the structure has been determined and installed, it is virtually impossible to change it. However, when the vehicle detector is operated, the direction of the vehicle detector changes due to abnormal weather (strong wind, typhoon, heavy rain, heavy snow, etc.), and accuracy of collected traffic information is greatly degraded if it is not corrected. In addition, when the road is expanded or the geometry is changed, it is necessary to adjust the length or direction of the structure arm so that accurate traffic information can be collected by accurately adjusting the detection position. Nevertheless, the existing structure is immobilized so that the length or direction of the arm can not be adjusted. Therefore, when the detection position is changed due to an abnormal climate, a road extension, or a geometry change, there is a problem that the structure itself must be installed to correct the detection position. In this case, the structure should be removed using a heavy equipment such as a forkläne, and then moved to a proper position to install the structure again. This process has a problem that demolition and re-installation costs of the structure are largely involved.

The length of the structure arm used for the vehicle detector is 3m, 5m, 7m according to the distance from the side of the road to the center of the vehicle. Therefore, there is a problem in that it is difficult to set the accurate detection position when the distance from the road side installation position to the center of the vehicle is 4m, 6m, 8m, and the like.

The lower pole 110 is fixed and installed at a predetermined height.

The upper pole 120 is located on the upper side of the lower pole 110, and a cross bar 130 to which the vehicle detector 140 is fixed is coupled.

The crossbar 130 may include an outer arm 130a having a hollow and an inner arm 130b coupled to the inside of the outer arm 130a and coupled to allow linear reciprocating motion.

The rotating device 150 is supported on the lower pole 110 and is coupled to the upper pole 120 to rotate the upper pole 120 at a certain angle.

The rotating device 150 includes a driving motor 151 fixed to the lower pole 110 as shown in FIG. 3, a driving motor 151 fixed to the first motor shaft 152 of the driving motor 151, And a second motor shaft 155 coupled to the upper pole 120 to rotate the upper pole 120 in accordance with rotation of the driving gear.

A method of adjusting the detection position of the structure of the vehicle detector constructed as described above will be described below.

(Manual change of crossbar position - change of direction)

First, the rotating device 150 is provided at the lower end of the upper pole 120. When the rotating device 150 is rotated, the entire upper pole 120 rotates little by little. At this time, the rotary device 150 has a structural characteristic that it can rotate the upper pole 120 360 degrees. The upper pole 120 is rotated by a desired position and then fixed to the upper pole 120 and the other pole is fixed to the lower pole 110 as shown in FIG. (120) and the lower pole (110). The fixing device 180 is installed in four directions so that the cross bar 130 can be firmly fixed, and is not shaken by strong winds or the like.

(Manual bar length change)

2 and 4, when the handle 172 provided in the cross bar length adjuster 170 is rotated in a clockwise direction, the inner arm 130b of the cross bar 130 advances to move the cross bar 130 ) Becomes longer. That is, since the handle 172 is connected to the center axis of the length adjusting unit 171, if the handle 172 is rotated clockwise, the length adjusting unit 171 also rotates clockwise. At this time, since the one end of the length adjuster 171 and the inner arm 130b are toothed, the inner arm 130b moves forward as the length adjuster 171 is rotated in the clockwise direction.

On the other hand, when the length adjusting unit 171 is rotated counterclockwise, the inner arm 130b moves backward, and the length of the crossbar 130 is shortened.

When the above-described rotating device 150 and the cross bar length adjusting device 170 are implemented by a motor, the length of the cross bar 130 can be adjusted by rotating the upper pole 120 semi-automatically.

3, first, an angle to be rotated is set by using a rotation angle setting button provided on the input unit 161 of the traffic situation information collecting apparatus 160. In other words, when the rotating apparatus 150 is implemented as a driving motor as shown in FIG. The first control unit 163 of the traffic situation information collecting apparatus 160 controls the drive motor 151 to rotate by a predetermined rotation angle through the motor driving unit 165. When the driving motor 151 rotates in this manner, the driving gear 154 fixed to the first motor shaft 152 rotates, and the second motor shaft 155 rotates. Accordingly, the second motor shaft 155 rotates, The upper pole 120 coupled to the upper pole 120 is also rotated.
