Description

Monitoring method for entrance or exit of vehicle and system

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to incoming and outgoing vehicle monitoring, and more particularly, to a method and system for monitoring vehicles and loads entering and leaving a specific purpose area such as a waste disposal plant.

There are parking lots for parking of vehicles in buildings, areas, etc., where a large number of vehicles enter and exit, such as apartments and large shopping malls, and access management using a vehicle number is performed by a few administrators. However, it was difficult for a few managers to manage all the vehicles entering and leaving.

In order to solve the problems as described above, a parking management system for automatically managing vehicles entering and exiting any area has recently been used. The automated parking management system automatically recognizes the vehicle number of the entering and exiting vehicle and determines whether to permit access according to the vehicle. Vehicle number recognition may be classified into a method using a radio frequency (RF) tag, a high pass, a loop sensor, and a camera. The method of using the RF tag has a disadvantage in that the driver has to approach the card to the RF reader, and thus, it is not possible to quickly enter and exit the vehicle, and cause inconvenience to the user. In addition, the high-pass method requires the high-pass equipment to be installed in the vehicle, which incurs an additional installation cost for the user's vehicle, and also makes it impossible for the visitor to manage because there is no high-pass. In addition, the roof sensor method requires a loop sensor to be buried in the ground, so the construction cost of the system is greatly increased, and when an error occurs in the system and the repair is required, the access road or the exit path of the parking lot must be controlled. There is a disadvantage that the entry of the vehicle for parking is impossible. Of course, in order to solve the above problems, recently, a technology of photographing a license plate of a vehicle with a camera and recognizing a vehicle number using a character recognition technology is also used.

However, the conventional parking management system is used only to recognize vehicle identification information that can identify a vehicle such as a vehicle number, but general apartments, shopping malls, etc. only need to identify vehicles that are entering and leaving, but a waste disposal plant, a garbage dump, etc. Must manage the goods loaded on and off the vehicle. In general, when a waste treatment plant uses a cargo vehicle to import and export cargo such as waste, the weight of the cargo is added, and the cost or transportation cost according to the weight of the cargo is calculated and managed accordingly. Therefore, it is necessary to manage the type (characteristic) and the amount of cargo loaded on the vehicle entering or leaving.

Conventionally, a method of measuring the weight of a vehicle using a weighing device and determining whether to enter or exit by directly checking the type of cargo loaded in the vehicle together with the measured weight is used.

That is, according to the conventional weighing management, the manager must check the property information according to the loaded cargo one by one with the vehicle number of the vehicle to be loaded and unloaded. Accordingly, statistical management is difficult and there is a problem that the manager always waits at the doorway. Moreover, if managers incorrectly check the characteristics of loaded cargo, or manage the inbound and outbound vehicles with the wrong intention, there is a serious problem.

Accordingly, the present invention has been made to solve the above-described problems, and to provide a loading and exit monitoring method and system for determining whether or not to enter and exit by checking the appearance of the cargo loaded on the vehicle to be loaded or unloaded.

1 is a block diagram schematically illustrating a waste treatment plant loading / unloading vehicle monitoring system for managing load characteristics of a loading / unloading vehicle according to an embodiment of the present invention.

Referring to FIG. 1, an entry / exit vehicle monitoring system according to the present embodiment includes one or more entry / exit processing units 10-1, 10-2,. 30-2, ..., 30-n, hereafter referred to as 30), and the central management unit 50.

The entrance and exit processing unit 10 is provided at the inlet and / or exit of the waste treatment plant, and interlocks with the entrance and exit management unit 30 so as to identify a vehicle to be entered or discharged (hereinafter referred to as "entry and exit") to determine whether or not to enter or exit. Function. For example, the entrance / exit processing unit 10 may include a breaker to control the entry / exit vehicle only for a vehicle in which the entry / exit permission is authenticated.

In addition, the entry / exit processing unit 10 according to the present embodiment is provided with a camera such as CCTV to take a picture of the vehicle entering and leaving. The captured image is used to read the characteristics of the cargo loaded on the vehicle. According to an embodiment, the appearance of the cargo may be read by the entry / exit management unit 30 that receives the image photographed by the entry / exit processing unit 10. Of course, the entry / exit processing unit 10 may directly read the properties of the cargo loaded in the vehicle for faster property reading and control of the entry / exit vehicle, but in the following description, when the entry / exit management unit 30 reads the properties of the cargo. This will be described as an example. That is, the entry / exit processing unit 10 functions to acquire vehicle identification information (vehicle number, vehicle model, etc.) and information (reading image, etc.) for reading the appearance information of the vehicle entering and leaving the vehicle, and the authentication process accordingly is performed by the entry / exit management unit ( 30).

In addition, the entry / exit processing unit 10 is provided with a weighing means for automatically or manually weighing the vehicle in and out, and the weight of the vehicle in and out may be measured.

The entrance / exit management unit 30 receives image information photographing the load together with the vehicle identification information received from the entry / exit processing unit 10, and verifies whether the entry / exit vehicle is permitted and verifies the vehicle identification information and the appearance information of the entry / exit vehicle information. Function to save. In addition, when the input / output vehicle weight information is received from the entry / exit processing unit 10 as described above, the data server may record the corresponding weight information together as the entry / exit vehicle information.

The central management unit 50 performs a function of receiving and integrating and managing vehicle information from one or more entry and exit management units 30. Accordingly, the manager of the central management unit 50 can monitor the status of all vehicles entering and exiting a waste treatment plant. It is possible to control and monitor the amount of traffic in the waste treatment plant.

In general, a plurality of vehicle entrances and exits are often provided in one waste treatment plant, and thus, a plurality of entry and exit processing units 10 and entry and exit management units 30 may be provided. Accordingly, the central management unit 50 collects and manages incoming and outgoing vehicle information from all the entry and exit management units 30, thereby monitoring the status of all vehicles entering and leaving the waste disposal plant.

Of course, the central management unit 50 may not only monitor the incoming and outgoing vehicle of one waste treatment plant as described above, but may also integrate and manage a plurality of waste treatment plants. For example, unique identification information is set in advance for each waste treatment plant, and when the inlet / out vehicle information is collected from the entry / exit management unit 30 provided in each waste treatment plant, the waste treatment plant may be integratedly managed to correspond to the corresponding waste treatment plant. For example, when the central management unit 50 receives the entry / exit vehicle information from the entry / exit management unit 30 of the waste disposal plant A, the central management unit 50 may manage the entry / exit vehicle information as integrated entry / exit vehicle information according to the waste disposal plant A. In other words, one central management unit 50 integrates and manages incoming and outgoing vehicle information of a plurality of waste treatment plants. Hereinafter, for convenience of description, the central management unit 50 will be described taking an example of managing one waste treatment plant.

Hereinafter, the detailed configuration of each component of the entry and exit monitoring system according to the present embodiment will be described.

2 is a block diagram showing a detailed configuration of each configuration of the input and output monitoring system according to an embodiment of the present invention, Figure 3 is a configuration of the entry and exit processing unit of the input and output monitoring system according to an embodiment of the present invention. This is an example.

First, referring to FIG. 2, the entrance / exit processing unit 10 includes a vehicle recognition unit 12, a weighting unit 14, and a camera unit 16. The vehicle recognizing unit 12 functions to recognize vehicle identification information such as a vehicle number, a vehicle model, etc. of a vehicle entering or leaving a vehicle within a predetermined distance, for example, using an RF (Radio Frequency) tag as described above. Any one or more of a method, a method using a high pass, a method using a loop sensor, and a method using a camera may be used. Hereinafter, for convenience of description, a method of photographing a license plate of a vehicle using a camera and recognizing a vehicle number from an image photographed using a character recognition technology will be described as an example. That is, the vehicle recognition unit 12 may include a next identification camera.

The weighing unit 14 functions to weigh the weight of the vehicle in or out of the vehicle. The weighing unit 14 may be implemented so that an administrator can weigh the vehicle manually entering and leaving the vehicle. More preferably, the weighing unit 14 may be provided with automatic detection means for automatically detecting the weight of the vehicle on the shipping detection plate (not shown). have.

The camera unit 16 functions to photograph a vehicle entering and leaving, and the image captured as described above is used by the entry and exit management unit 30 to read the characteristics of the cargo loaded on the vehicle. Here, the camera unit 16 is more preferably implemented in a position that can photograph any one or more of the rear, side, top of the vehicle in order to more accurately photograph the load of the vehicle entered within a certain distance. Here, when photographing the load, it is natural that the load may be photographed itself. Of course, in the case of a vehicle equipped with a separate stack, only the stack may be photographed. Accordingly, even in the case of the loading box, since the upper surface is mostly opened, more preferably, the upper surface of the vehicle is photographed so that a load provided in the loading box can be photographed even in a vehicle equipped with the loading box. However, hereinafter, for convenience of explanation, it is assumed that the freight vehicle is not provided with a separate compartment, and accordingly, a case of photographing the side of the vehicle, that is, the side of the load will be described as an example.

Although not shown in FIG. 2, the entry / exit processing unit 10 may include a sensor unit (for example, a roof coil 350 installed on the floor shown in FIG. 3) for recognizing a vehicle entering within a predetermined distance and entering the vehicle. It may further include a blocking portion (eg, blocking rod 330 shown in FIG. 3, etc.) for passing or blocking. For example, when the sensor unit recognizes that a certain vehicle enters within a predetermined distance, the vehicle recognition unit 12 and the camera unit 16 perform the above operation. This will be apparent to those skilled in the art, so a detailed description thereof will be omitted.

Referring to FIG. 3, which illustrates the structure of the entry / exit processing unit 10 for convenience of understanding, when the freight vehicle enters and passes the loop coil 350, the vehicle identification camera 320 moves the vehicle to include the license plate of the vehicle. The vehicle identification number including the vehicle number (and the vehicle model) is recognized by imaging. The recognized vehicle number may be displayed on the vehicle indicator 360 to allow the vehicle driver to confirm. In addition, the weight of the vehicle is measured by the shipping detection plate 340, and the vehicle is photographed so that the feature reading camera 310 for reading the feature of the load 302 includes the load 302. Therefore, the vehicle identification information, the weighing information of the entry and exit vehicle, and the constellation information (that is, the captured image) of the load 302 are acquired by the entry and exit processing unit 10.

Referring again to FIG. 2, the entry / exit management unit 30 includes a vehicle information storage unit 32, a weighing information storage unit 34, an image information storage unit 36, and a main control unit 38.

The vehicle information storage unit 32 stores vehicle identification information such as a vehicle number and a vehicle model as vehicle information on vehicles that are permitted to enter and exit (hereinafter referred to as "registered vehicles"). Accordingly, when the vehicle number of the vehicle entering and leaving the vehicle is received from the entry / exit processing unit 10, the entry / exit management unit 30 searches the vehicle identification information of the vehicle information storage unit 32 to determine whether the vehicle is a vehicle that is permitted entry / exit vehicle. can do.

The weighing information storage unit 34 stores weight information, that is, weighing information of the incoming and outgoing vehicles, weighed by the entry and exit processing unit 10 and received. Here, the weight information stored in the weight information storage unit 34 may be stored as the weight information received from the entry and exit processing unit 10, according to another embodiment of the vehicle that is not loaded on the basis of the vehicle model information of the vehicle The remaining weight information minus the original weight may be stored in the weighing information storage unit 34. For convenience of understanding, for example, the entry and exit vehicle is 1 ton truck A cargo, the weight information of the vehicle received from the entry and exit processing unit 10 is 3 tons, the information that the weight of the A model is 1.5 tons Assuming that the state is stored in the vehicle information storage unit 32 of the management unit 30, 1.5 tons minus 1.5 tons from 3 tons can be stored in the vehicle information storage unit 34 as weight information. To this end, as described above, the vehicle information storage unit 32 stores vehicle weight information as vehicle type information together with the vehicle number of the registered vehicle.

The image information storage unit 36 stores the captured image received from the entry / exit processing unit 10. The photographed image is used to determine the appearance of the load on the entry / exit vehicle.

Although not shown in the drawing, the image information storage unit 36 stores a captured image storage space for storing the captured image received from the entry / exit processing unit 10 and a basic image according to various loads serving as basic information for determining the appearance. It may include a basic image storage space, which can be logically or physically divided. Here, for example, the basic image may be an image corresponding to each waste such as steel, cement, and the day after tomorrow.

The main controller 38 determines the appearance of the load according to the captured image by using the base image stored in the image information storage unit 36. In the photographed image, the load is detected by using a contour detection technique, and the base image most similar to the color, brightness, and contour of the detected load is searched. Image comparison technology for determining whether or not to compare the two images by comparing the brightness, color comparison, contour comparison, etc. is a well-known technique, and since a variety of image comparison techniques are being developed, a detailed description thereof will be omitted. The reason why the contours of the load image and the base image detected in the captured image are compared is that the shape loaded on the vehicle may be different for each load. For example, if the load is a moire, the upper contour will be curved (see Figure 6), whereas if the load is steel, the upper contour may be uneven, and if the load is paper, the middle of the steel and the moire. It will have a contour with a curve that is evenly rounded. In other words, the contour feature of the load image is compared with the base image. Therefore, by comparing the contour of the upper portion of the load image with the base image, it is possible to perform more accurate load property determination.

In addition, in order to more accurately determine the property, according to another exemplary embodiment, the main controller 38 may provide a user interface screen to be output to the outside through a display screen having the determined property information of the load to be checked and corrected by an administrator. It may be. That is, the manager may check whether the image information of the entry / exit vehicle is properly determined by checking the captured image and the determined image information displayed on the output screen.

According to another embodiment, the main control unit 38 may use the weighting information of the entry / exit vehicle to determine the properties of the load more accurately. That is, the main controller 38 may determine a more accurate image using the weighting information and the captured image of the load. For example, in the case of a load of the same volume, since the weight of steel and moire may be different, the properties of the load can be determined using the size and weight of the load extracted from the captured image. A process of determining the load property of the in / vehicle vehicle by the main controller 38 will be described later in detail with reference to the related drawings (FIG. 2).

Referring back to FIG. 2, the central management unit 50 includes an entry / exit vehicle information DB 52, a monitoring unit 54, and a user interface unit 56.

In-and-out vehicle information DB 52 stores and stores in-vehicle vehicle information including vehicle identification information, weighting information and property information received from one or more entry / exit management units 30 in a database. This can be used as basic data for the integrated management of all incoming and outgoing vehicles in the waste treatment plant.

The monitoring unit 54 is for enabling the user to monitor the entry / exit vehicle information, which will be apparent to those skilled in the art, and thus a detailed description thereof will be omitted.

As shown in the figure, the central management unit 50 may include a user interface unit 56 for allowing an administrator to set an update of a registered vehicle, an allowable weight of a load, a kind of load that is allowed in and out of a vehicle, and the like. That is, the administrator can update the registered vehicle information stored in the entry / exit control unit through the user interface unit 56 of the central management unit 50, and also set the type of load characteristics allowed for entry / exit vehicles, the limit of the weight of the load relative to the freight vehicle, and the like. This may be used later to determine whether the entry / exit management unit 30 is a vehicle that attempts to enter and exit a vehicle that is allowed to enter and exit the vehicle, and carries a load of allowed properties and weights.

Therefore, the central management unit 50 may transmit the information input from the administrator through the user interface 56 to the entry and exit management unit 30 so that the information is updated.

Hereinafter, the entry / exit processing unit 10 and the entry / exit management unit 30 will describe the authentication process of the entry / exit vehicle and the acquisition process of the entry / exit vehicle information.

In general, in the case of a waste disposal plant, a vehicle in which a vehicle is normally loaded is loaded with a mixture of non-recyclable and possible materials, and a vehicle that is discharged may be classified as a vehicle having only incineration waste or only recycled materials. Can be. Therefore, the entering vehicle only needs to authenticate the vehicle as to whether the entering vehicle is permitted, but the leaving vehicle needs to perform authentication according to the loaded load.

Therefore, in the following embodiment, a vehicle entering is used to determine whether to allow admission using only a vehicle number, and a vehicle going out is determined using an example of determining whether to allow exit using the property information and the time ration information.

4 is a flowchart illustrating an authentication procedure and a vehicle information acquisition process of a parking vehicle according to an embodiment of the present invention, and FIG. 5 is a process of acquiring the authentication procedure and the parking amount information of a parking vehicle according to an embodiment of the present invention. FIG. 6 is a flowchart illustrating a process, and FIG. 6 is an exemplary diagram of extracting a load image from a vehicle-captured image for determining a load property according to an embodiment of the present invention.

Before describing with reference to the drawings, the subject performing the process according to Figs. 4 and 5 is the entry and exit processing unit 10 and the entry and exit management unit 30, since the details are described above, duplicate descriptions will be omitted below. .

First, referring to FIG. 4, the entrance / exit processing unit 10 recognizes when the vehicle enters the roof coil within a predetermined distance or as described above (S410), and acquires the vehicle number of the vehicle (S420).

The determination of whether the acquired vehicle number is a registered vehicle is performed by the entrance / exit management unit 30 (s430), and as a result, an error message may be output if the vehicle number is not a registered vehicle (445). The error message may display a warning sound or a warning message for the vehicle driver to recognize, and also notify that the vehicle that is not registered with the central management unit 50 attempts to enter so that the administrator of the central management unit 50 can recognize the error message. It may be. The vehicle that is not registered may enter only after being registered as a registered vehicle in the entry / exit management unit 30 by performing a vehicle registration procedure.

On the contrary, if it is determined that the vehicle which attempted to enter is a registered vehicle, the breaker is opened to allow the vehicle to enter (s440), and the photographing of the fag and load of the entry / exit vehicle is performed (s450).

The vehicle number (which may also include vehicle model information as described above), the weighting information and the load photographing image of the entered vehicle are transmitted to the central management unit 50 as the received vehicle information (S460).

Here, in the present embodiment, the process of reading the properties of the photographed load is omitted, but according to another embodiment, the loading property information including the load property information is performed to the central management unit 50 after the load property reading process is performed after s450. May be sent.

Therefore, the central management unit 50 can manage the load weight and property information for every vehicle entered into a database.

Referring to FIG. 5 illustrating a processing process according to the amount of leaving, the entry and exit processing unit 10 recognizes when the vehicle enters the roof coil within a predetermined distance or as described above (5410), and recognizes the vehicle (s520). ). Here, the vehicle recognition may acquire the vehicle number of the vehicle, and may recognize the vehicle weight information of the vehicle according to the vehicle type and the vehicle. The weight information of the vehicle is used to measure the weight of the load, which has been described above, and thus redundant description will be omitted.

The entered vehicle is weighed and an image is taken to include a load (S530). The weight of the load is calculated by subtracting the weight of the vehicle from the measured weight. Of course, the weight of the driver is included, but the weight of the load may be calculated by disregarding the weight of the driver or considering a certain weight (about 70 kg) as the weight of the driver.

Then, the appearance of the load is read (s540). As described above, the determination of the load property is performed by comparing the photographed image with the basic image according to the expected load, and the weight information of the load may be used to determine the property.

Referring to FIG. 6 illustrating a constellation determination method, after capturing the side of the vehicle and acquiring the captured image 610, the captured image 610 detects the outline of the vehicle or the outline of the load to detect the load image 630. ). Here, once again, as described above, the photographed image according to the top or rear surface of the load may be used by photographing the top or rear surface of the vehicle.

The extracted load image 630 is compared with each of the pre-stored base images to search for a base image having the most similar color, luminance, outline, and the like to determine the appearance of the load.

Here, as described above, the manager may be inquired as to whether the properties of the read-outs are correct. In other words, the manager may display the captured image and the read feature information to the administrator for confirmation. For example, after the captured image and the image information are transmitted to the central manager and confirmed by the manager, the next step may be performed.

In addition, when the image is not read out due to the uneven quality of the captured image or the image being taken at the wrong angle, the load may not be easily seen, an error message may be output to inform the administrator.

It is determined whether the vehicle attempts to leave the vehicle with the loads of the allowed properties and weights (s550), and when the vehicle is dismissed without the allowed load, an error message is output (s555). As in the case of entering the vehicle, the error message processing may display a warning sound or a warning message so that the vehicle driver can recognize the vehicle, and the vehicle that does not like the wrong load to the central management unit 50 can be recognized by the administrator of the central management unit 50. You may be notified that you are attempting to leave.

If it is determined in S550 that it is determined that the vehicle has attempted to leave with the allowed load, the breaker is opened (s560), and the vehicle identification information, the load weight information, and the load property information are transmitted to the central management unit 50 as the discharge quantity information. (s570). Therefore, the central management unit 50 can manage the load property and weight for each vehicle to be discharged by database.

The method of the present invention as described above may be implemented in a program and stored in a computer-readable recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.).

The present invention is not limited to the above embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.
