Description

Apparatus for installing multi lane radar type counter for measuring traffic volume}

The present invention relates to a radar-type traffic volume measuring apparatus and an installation apparatus therefor, and more particularly, a multi-lane detecting radar type traffic volume measuring apparatus capable of recognizing and integrating the quantity of traffic passing through multiple lanes of the road at once and the outside of the road. The present invention relates to an installation device configured to be easily attached to or detached from an existing facility in the form of a column.

Collecting and arranging various road traffic information is necessary for smooth road operation and accident prevention in the short term, and it is a key factor in establishing road traffic policy in the long term, and the system for collecting and arranging such traffic information is recognized variously. It is being advanced and integrated with the development of technology and computer communication technology.

The most basic and important information in road traffic is the quantity and speed of vehicles passing through a particular road point or section at any point in time. Two methods are used.

The first method is a method where a person directly counts through a manual counter in the field, and since it requires a lot of manpower and time, the usage is gradually reduced. The second method is to measure the amount of traffic passing through the road using mobile traffic checking equipment. In addition, it is possible to use a geomagnetic sensor and a radar detector as a device for automatically measuring traffic volume.

The geomagnetic sensor equipment measures the traffic through the vehicle by detecting the magnetic field generated by the vehicle. The equipment using the radar detector uses radar that emits radio waves of a specific frequency, such as the ISM band of 24.125 GHz. Measure the traffic volume.

This measurement of road traffic information can be carried out continuously for a long period of time by fixedly installing equipment on important traffic points, but new equipment or new equipment on new roads or other points of existing roads may be installed depending on road conditions and road conditions. It is necessary to collect traffic information as you move from point to point as needed. In this case, it is necessary to collect the information collecting device such as the traffic volume from the existing installation location and install the new location.

However, the geomagnetic sensor installed directly on the road has problems in about three aspects.

First of all, inconvenience and danger of the installation method, since the geomagnetic sensor is attached to the center of the road by the person who wants to measure directly by using a fixed mat, the risk of traffic accident by the passing vehicle is very high. The driver can be a big threat. Of course, this same risk exists when returning equipment.

Secondly, due to the adverse effects of road installation, the geomagnetic sensor has a high risk of damage to geomagnetic sensors caused by large vehicles because it is attached directly to the road. It may cause malfunction.

The third is the limitation of use by the weather, and there are many restrictions on the operation of the equipment due to the influence of the weather. In other words, it is almost impossible to attach the geomagnetic sensor to the road using rain mats in rainy weather. When the weather falls below zero in early winter weather or the temperature drops below zero, the adhesion of the earth to the fastening mat becomes weak, which increases the risk of equipment loss or damage. Installation will be impossible.

In addition, there is a problem that it is difficult to make a mobile equipment to move and use many places because there is a lot of inconvenience in the mobile installation equipment using the radar detector. For example, when the existing radar detector is installed on the upper part of the road, there is a hassle and risk of detachment such as a geomagnetic sensor method, and it is often installed at a height of 5m or more to secure an appropriate detection range by using an off-road structure column. In this case, a separate power supply box and a controller enclosure are additionally supplied and operated, and it is very inconvenient to install such equipment at a high point of the column, and it is time-consuming and expensive, and also increases the risk of worker safety.

Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic conceptual view showing the overall configuration of a traffic measurement system including a multi-lane detection radar type traffic measurement device of the present invention, Figure 2 is a radar module, a signal processing module and a battery (power module) is a housing ( An embodiment of an integrated multi-lane sensing radar type traffic volume measuring device integrally coupled and installed in a case) is shown.

Referring to the system configuration shown in FIG. 1, the traffic volume measuring device 100 is installed in a pillar installed along the road, and the antenna of the radar module is installed to direct a predetermined section of all lanes of the road ahead. That is, the radio wave emission solid-angle range and the effective sensing distance range of the antenna surface of the radar module cover a predetermined section of all lanes of the measurement target road.

On the other hand, the radar antenna installation direction and cover area setting is important in the device of the present invention, the vehicle and other vehicles can pass adjacent at any time, in this case, the large vehicle or the front vehicle shields the radar radio wave for the small vehicle or the rear vehicle Thus, a small vehicle or a vehicle behind it enters a radio wave shade band, thereby limiting the accurate detection of the presence of a small vehicle and the number of vehicles. This problem is even more important when a single radar-type traffic measurement device is used to detect vehicles passing through multiple lanes together. It is necessary to use a method of minimizing a vehicle that is temporarily caught by a radio shading band to be installed at a relatively low column position so that accurate traffic measurement can be performed.

In this case, the present invention can improve traffic accuracy by setting a multi-loop zone as an additional function, dividing the lane sections into a plurality, and measuring a traffic value (vehicle number) of each section to select a maximum value. have.

For example, a plurality of virtual loops may be set in a section of 30 to 100 m in front of the measuring device to detect multiple vehicles to be measured, and at least one of them may be detected as a plurality of separate vehicles or a plurality of distinctly overlapping vehicles instead of a single vehicle. If so, the traffic volume is calculated by selecting a case where it is detected as multiple vehicles.

Traffic information (traffic volume information) obtained by the traffic volume measuring apparatus 100 of the present invention is transmitted to a nearby AP or a hub 210 through short-range wireless communication, and the hub is connected to a communication network such as the Internet to which the hub is connected. It is transmitted to the control server 220, etc. of the traffic center through, and the information can be retrieved from the required connection terminal 230 or used to monitor the situation.

Existing geomagnetic sensor is a very high risk of a traffic accident in a way that the person directly installed in the center of the road, but the device of the present embodiment is outside the road as shown, and does not install a separate booth, road signs or street lights It is installed in the dragon pillar. In this installation location, the operator does not have to enter the road directly for installation.

Therefore, by using the present embodiment, the worker can be safely protected by the traffic vehicle during the installation and removal work from the risk of traffic accident, and can not be damaged or lost by the traffic vehicle because there is no contact with the traffic vehicle.

Referring to FIG. 2, the radar module 10, the signal processing module 20, the power supply module 30, and the like are integrated into one housing 41 (box, case) of the housing and the mounting module 40 of the traffic measurement device. Are combined and installed. Enclosure 41 including each module can achieve a waterproof state by installing a packing (not shown) in close contact with each other when the enclosure is assembled in preparation for rainy weather, and also prevents the ingress of external dust, such as water However, problems such as short circuits and short circuits caused by stacking can be prevented.

The enclosure 41 is connected to the mounting bracket 43, and is installed on the side wall of the pillar A on the road. To this end, the bracket 43 has a band 431 installed to surround a part of the side wall of the pillar and a fastening means 433 such as a bolt nut at a portion of the band, through which the bracket is reduced or widened so that the bracket is connected to the pillar. Allow to be removed.

FIG. 3 shows an embodiment of a traffic measuring apparatus different from FIG. 2. In this embodiment, the case 141 of the main body in which the signal processing module 120 is embedded in the form of a motherboard is formed with insertion grooves 141a and 141b serving as guide grooves, and the radar module 110 and the battery 130 are provided. Inserted into the insertion groove in the form of a cartridge, it is configured to be removable in one-touch manner.

For the functional coupling between them after insertion, the bottom of the insertion groove of the site where they are detached or the cartridge contact surface corresponding to the bottom are installed such that necessary power and signal lines can be connected in the form of pins and sockets of the connector.

At the inlet of the insertion grooves 141a and 141b, packings 141c and 141d made of an elastic soft material are installed to prevent external rainwater or dust from entering. When the cartridge-shaped modules are inserted to be completely connected to the main body case 141, the cartridge is fixed to the main body case 141 while the cartridge corresponding portion 113 is pressed against the packings 141c and 141d.

Although not shown here, when inserting the cartridge for detachable one-touch type, when the elastic body such as a spring interposed between the cartridge and the main body is compressed and completely connected, the fixing device such as the latch and the groove installed in the cartridge and the main body case If the cartridge is fixed, and the cartridge is pushed a little further into the insertion groove to release the cartridge, the latch that secures the cartridge is released from the groove, and the cartridge is partially ejected from the insertion groove by the restoring force of the compressed elastic body. The ridge and the main body case can be formed.

 The radar module 110 basically includes a radar antenna that emits radar radio waves in an external constant angle range and receives reflected waves reflected from an external object, and receives an oscillation device that generates radio waves of a predetermined frequency and receives an electric signal. It is provided with a converter for switching to. The antenna component of the radar module is exposed to the outside even when inserted into the main body case and made to face the road surface to be monitored.

The configuration of the radar module 110 is common to the existing traffic detection radar technology in terms of basic configuration, and the reflected wave processing for the radio emission range and its range for multi-lane detection is a hardware control and software for the existing radar It can be implemented through, which is already known in the art, so the detailed description thereof will be omitted here.

The signal processing module 120 can be thought of as a kind of computer device. The radar module 110 processes the electrical signal converted and received by the reflected wave through the processor by means of a built-in processing program, and temporarily stores the result in a predetermined format, accumulates the result over a predetermined period or performs other secondary processing. You can get the information you want.

For example, by using the hardware and software constituting the signal processing module 120, the number of vehicles passing through the area at a certain time to identify something as a valid vehicle through a signal detected for each lane and each section so as not to be missed or duplicated. Such traffic information may be stored through its own storage location and removable auxiliary memory, and may be transmitted wirelessly through a communication module to a central control station (transport center, etc.) through an access point or hub of a neighboring transmission network. Therefore, by using the auxiliary memory detachment or wireless information communication can easily retrieve the traffic information at any time.

The battery 130 preferably forms a power supply module so that maintenance can be performed with a small number of people. Therefore, it is preferable to use a secondary battery having a charging capacity capable of operating for about 72 hours without replacement. In addition, it is preferable to employ a lithium ion battery or a lithium polymer battery that can increase the amount of charge per unit mass to favor the detachment and movement of the system.

By using the communication module, by modifying, updating, and resetting the processing program or operating conditions of the processing device module in an external controller or a controller for a remote controller that can be easily installed in a nearby hub while leaving the device of the present invention in an existing installation place, It can be used and can monitor the malfunction. Even if a malfunction occurs, the module can be initialized or error corrected.
