Description

Edge computing device and corresponding parking control method for parking and parking status control in metropolitan parking lots {edge computing device and method for parking control}

The present invention relates to parking management technology. More specifically, in a metropolitan parking lot with a very wide parking area, parking lot users who do not park normally in parking spaces are instructed to park normally, so that unmanned management can be efficiently performed even in metropolitan parking lots. This relates to an edge computing device for parking and parking status control in a metropolitan parking lot and a parking control method accordingly.

This invention is the result of a local innovation project based on local government-university cooperation conducted in 2022 with the support of the National Research Foundation of Korea with funds from the Ministry of Education (2022RIS-006).

In large parking lots such as department stores, apartments, and paid parking lots, loop coils are embedded in the road surface within the parking lot to manage the entry and exit of vehicles, and vehicle alarm devices that detect passing vehicles and activate warning lights are installed.

However, burying loop coils in the road takes a lot of time and money, and even after they are buried, there is a problem that they often fail to function properly due to short circuits and disconnections.

In addition, the method using a loop coil can only detect whether a vehicle is passing through a given location, so there was a problem in that two loop coils had to be buried side by side in order to detect the vehicle's direction of travel.

Accordingly, in order to reduce labor costs due to the use of manpower to manage vehicles, cameras were installed at the entrance and exit sides of the parking lot, and the license plate of the entering vehicle was photographed and recognized as letters and numbers to identify the vehicle. is being developed. This system also has a loop coil buried in the vehicle entrance and a camera is installed in front of the entrance. When the entry of a vehicle is detected by the loop coil in the entrance, the camera photographs the vehicle's license plate and records the license plate. A method was used to extract the number of the vehicle entering the driveway from the video.

This technology includes patent number 10-0281675 registered with the Korean Intellectual Property Office. At the entrance, the local controller uses a vehicle detector to recognize entering vehicles and informs them of the situation through warning lights and an entrance situation board. At multiple exits, vehicle detectors, loop coils, and license plate recognition devices are installed to recognize the presence and type of vehicles leaving the vehicle. The vehicle body recognition device installed at each junction of the parking lot measures the height of the vehicle, and the local controller installed at each parking floor recognizes the parked vehicle through a vehicle detector, determines the presence or absence of the vehicle, the type of vehicle, and the vehicle. The master controller, which receives information according to the number, monitors the communication status and controls internal operations in case of emergency, and the main computer, which transmits and receives communications through the master controller, controls the overall internal operation while controlling the overall internal operation. We have launched a technology that allows vehicles to accurately and quickly navigate to a parking space within a parking lot by guiding them to the parking space at the shortest distance.

And Patent No. 10-1662224, registered at the Korean Intellectual Property Office, includes a plurality of cameras installed on the entrance and exit roads of each floor of the parking lot to capture surrounding images and vehicles within the shooting area; A plurality of warning lights installed on the entrance and exit roads of each floor of the parking lot to output warning sounds and warning lights; a vehicle management server that receives images captured from the plurality of cameras, stores them in a database, analyzes the images, and generates a warning light control signal corresponding to the driving direction of the vehicle; And controlling the operation of the warning light provided at the corresponding location according to the warning light control signal, and controlling the operating time of the warning light according to the length of the parking lot lamp at the location where the warning light is provided, so that the warning light is operated during the operating time. A parking lot management system using a camera including a warning light control device is being launched.

As mentioned above, various parking management technologies have been proposed and commercialized in the past, such as installing multiple cameras and warning lights in the parking area and having the vehicle management server perform parking management based on image information captured through the multiple cameras. .

However, in the past, as the overall management of the parking lot adopted a centralized control method, it was difficult to apply it to a metropolitan parking lot with a very large parking area.

To explain further, the conventional method of installing cameras or warning lights in all parking areas and connecting them to the service server by wire requires complicated installation work over a very long distance when applied to a metropolitan parking lot with a very large parking area. Of course, as the size of the parking lot grew, the number of cameras and warning lights increased exponentially, leading to the problem of overload on the management server responsible for centralized control.

Accordingly, there has been an urgent need to develop technology that can be easily installed even in metropolitan parking lots with very large parking areas and provide guidance information to parking lot users to intuitively understand the parking status.

In addition, there is an urgent need for the development of technology that can guide parking lot users who do not normally park in parking spaces to park normally in metropolitan parking lots where unmanned management has been difficult in the past.

To implement the parking status control mode and vehicle entry/exit control mode, the parking control edge computing devices operate independently or two or more are operated in combination.

Figure 2 illustrates the configuration of a parking control system formed by combining the above parking control edge computing devices.

Referring to FIG. 2, some of the parking control edge computing devices (1001~100N, 2001~200M, P001~P00L) provided in the parking control system are directly connected to the POE hub 200 and receive driving power. The rest are connected to other parking control edge computing devices and are driven by receiving power from the connected parking control edge computing devices.

In addition, some of the parking control edge computing devices (1001~100N, 2001~200M, P001~P00L), that is, parking control edge computing devices that independently control entry and exit into the control area, which is a small parking area, are located in the control area. By detecting vehicles entering or exiting the control area, the number of parked vehicles in the control area is subtracted from the predetermined number of full vehicles to detect the number of vehicles available for parking, as well as information on entering or exiting the vehicle and the number of vehicles available for parking. In addition to recording the information in the parking status information, lights in colors corresponding to the number of vehicles available for parking are output to guide parking lot users. In this way, the parking control edge computing device that independently performs entry and exit control for the control area, which is a small parking area, may be installed at the entrance and exit area for the control area, as illustrated in FIG. 5.

Some of the above parking control edge computing devices (1001~100N, 2001~200M, P001~P00L), that is, parking control that is combined with other parking control edge computing devices to perform entry and exit control for the parking control area, which is a small parking area. Edge computing devices detect vehicles entering or exiting the parking control area and subtract the number of parked vehicles in the control area from the predetermined number of full vehicles to detect the number of vehicles available for parking, as well as checking the number of vehicles entering or leaving the parking control area. Alternatively, information on exit information and the number of vehicles available for parking is recorded in the parking status information, and the parking status information is shared with other associated parking control edge computing devices through the POE hub 200, and the parking status information is shared with other parking control edge computing devices. The shared parking control edge computing device outputs lighting in a color corresponding to the shared parking status information. As shown in FIG. 6, two or more of these parking control edge computing devices are installed for one parking control area.

In addition, some of the parking control edge computing devices (1001~100N, 2001~200M, P001~P00L), that is, a parking relationship edge that controls the parking status of a predetermined number of parking spaces within the parking control area, which is a small parking area. Computing devices detect parking conditions for a predetermined number of parking spaces, and when parking conditions are abnormal, output colored lights and audio to warn of abnormal parking to guide parking lot users so that they can park normally. As shown in FIG. 7, these parking control edge computing devices are installed in a predetermined number of parking spaces.

In addition, the service server 300 and the database 302 are connected to the POE hub 200, and the service server 300 receives parking status information provided through the POE hub 200 and stores it in the database 302. Save.

The POE hub 200 supplies driving power to the parking control edge computing devices (1001 to 100N, 2001 to 200M, and P001 to P00L) and forms a communication path.

In addition, the parking control edge computing devices (1001~100N, 2001~200M, P001~P00L) are connected in series to form a supply path for driving power, so that even if the parking control edge computing device is not directly connected to the POE hub (200), other parking By allowing driving power to be provided from the control edge computing device, there is no need to connect and install too many wires to control entry/exit and parking status in a metropolitan parking lot with a large parking area, thereby forming a system for parking control. Make it easy to implement.

<Processing procedures of parking control edge computing devices>

Now, the processing procedures of the parking control edge computing device configured as described above will be described in detail with reference to FIGS. 3 and 4.

The control device 102 of the parking control edge computing device performs imaging through the camera unit 110 (step 500), receives imaging information according to the imaging, and moves based on the change between the previous frame and the current frame. Detect (step 502).

When movement is detected, the control device 102 of the parking control edge computing device checks whether the operation mode is set to the vehicle entry/exit control mode or the parking status control mode (step 504).

If the operation mode is set to the vehicle entry/exit control mode, the control device 102 recognizes the vehicle (license plate) from the image information (step 506). When the license plate is recognized from the image information (step 508), the forward movement of the vehicle, i.e., entering the vehicle, or the backward movement of the vehicle, i.e., leaving the vehicle, is detected based on the license plate recognition information (step 509).

The method of detecting entry or exit of a vehicle based on the vehicle license plate may be a method of detecting based on the change in size of the vehicle license plate of the previous frame and the next frame.

Another method is to detect the outline of the vehicle centered on the license plate, detect the front or rear features of the vehicle using the image information corresponding to the outline of the vehicle as an area of interest, and detect the front of the vehicle, that is, the vehicle's entrance or exit. A method of detecting the rear of the vehicle, that is, the vehicle leaving the vehicle, may be adopted. These features may include the presence or absence of side mirrors or driver's face recognition.

Another method is to detect the outline of the vehicle centered on the license plate, detect the change in size of the area corresponding to the outline of the vehicle from the previous frame and the next frame, and move the vehicle forward or backward according to the change in size. A method for detecting can be adopted.

As described above, after recognizing the vehicle license plate from the image capture information and detecting the forward or backward movement of the vehicle, the control device 102 determines whether the vehicle whose license plate has been recognized is a vehicle entering the parking control area. (Step 510).

If the vehicle is a vehicle entering the parking control area, the control device 102 checks whether a single parking control edge computing device is set to independently control the vehicle (step 512).

If the control device 102 is a parking control edge computing device that controls independently, the control device 102 increases the number of parked vehicles in the parking control area and detects the number of available parking vehicles by subtracting the number of parked vehicles from the predetermined number of full vehicles. In addition, entry information consisting of license plate recognition information and entry detection visual information for entering vehicles is generated and recorded in the parking status information (step 514), and the entry information is stored in the parking space belonging to the parking control area. It is transmitted to one or more parking control edge computing devices in charge of parking status control for the parking status (step 516). Thereafter, the control device 102 outputs lighting of a color corresponding to the number of parking vehicles through the LED lighting 112 to guide parking lot users (step 518). In this way, the parking control edge computing device that independently performs entry and exit control for the parking control area, which is a small parking area, may be installed at the entrance and exit area of the parking control area.

Unlike the above, if the control device 102 is a parking control edge computing device that controls a parking control area in conjunction with another parking control edge computing device, it increases the number of parked vehicles in the parking control area and also increases the number of vehicles parked in the parking control area. In addition to detecting the number of vehicles available for parking by subtracting the number of parked vehicles from the predetermined number of full vehicles, entering information consisting of license plate recognition information for entering vehicles, visual information of entering the vehicle, etc. is generated and recorded in the parking status information. (Step 520), the parking status information is combined with one or more parking control edge computing devices responsible for parking status control for parking spaces belonging to the parking control area, and another control device set as a joint control device to control the parking control area. It is transmitted to parking control edge computing devices (step 522). Thereafter, the control device 102 outputs lighting of a color corresponding to the number of parking vehicles through the LED lighting 112 to guide parking lot users (step 524).

Unlike the above, it is checked whether the vehicle is an entering vehicle or an exiting vehicle from the parking control area, and if the vehicle is an exiting vehicle (step 530), the control device 102 is independent of one parking control edge computing device. Check whether it is set to control (step 532).

If the control device 102 is a parking control edge computing device that it independently controls, it reduces the number of parked vehicles in the parking control area and detects the number of available parking vehicles by subtracting the number of parked vehicles from the predetermined number of full vehicles. In addition, vehicle exit information consisting of vehicle license plate recognition information and vehicle exit detection visual information for exiting vehicles is generated and recorded in the parking status information (step 534), and the parking status information is stored in the parking control area. It is transmitted to one or more parking control edge computing devices in charge of parking status control for the spaces (step 536). Thereafter, the control device 102 outputs lighting of a color corresponding to the number of parking vehicles through the LED lighting 112 to guide parking lot users (step 538).

Unlike the above, if the control device 102 is a parking control edge computing device that controls a parking control area in conjunction with another parking control edge computing device, it reduces the number of parked vehicles in the parking control area and also reduces the number of vehicles parked in the parking control area. In addition to detecting the number of vehicles available for parking by subtracting the number of parked vehicles from the predetermined number of full vehicles, exit information consisting of license plate recognition information for exiting vehicles, time of exit detection, etc. is generated and recorded in the parking status information. (Step 540), the parking status information is combined with one or more parking control edge computing devices responsible for parking status control for parking spaces belonging to the parking control area, and another control device set as a joint control device to control the parking control area. It is transmitted to parking control edge computing devices (step 542). Thereafter, the control device 102 outputs lighting of a color corresponding to the number of parking vehicles through the LED lighting 112 to guide parking lot users (step 544).

Unlike the above, when the control device 102 controls a parking area in association with another parking control edge computing device, the control device 102 provides parking status information from the other parking control edge computing device. It can be. When parking status information is provided from another parking control edge computing device (step 550), the control device 100 matches the identification information of the transmission side of the received parking status information to the identification information of the parking control edge computing device that it jointly controls. When matched, the parking status information for the parking control area is updated with the received parking status information, and lighting in a color corresponding to the number of vehicles available for parking in the updated parking status information is output through the LED lighting unit 112 (step 552). ).

In step 504, if the control device 102 is a parking control edge computing device for parking status control for one or more parking spaces, it waits until the movement ends (step 600), and then the control device 102 When the parking control edge computing device in charge of controlling entry and exit from the parking control area containing one or more parking spaces, which is in charge of (102), receives entry information, the control device 102 determines whether there is a change from the previous image information. In addition to determining, the vehicle (license plate) is detected (step 604).

When a new vehicle (license plate) is recognized from the image capture information, the control device 102 checks whether the license plate recognition area is located in a predetermined normal parking space area (step 606). Thereafter, the control device 102 provides parking information (parking space + license plate information + parking time information) for the parking space identification information corresponding to the normal parking space area in which the vehicle number plate was recognized to the entry information of the newly recognized license plate. The recorded parking space status information is created and stored (step 610).

Thereafter, the control device 102 transmits the parking space status information to the parking control edge computing device in charge of parking control for the parking management area containing the parking space, and also transmits the parking space status information to the parking space status information. Illumination is output through LED lighting 112 (steps 612 and 614).

After the movement ends, if the license plate on which the vehicle entry information was received is not recognized and a change from the previous image information in which no movement was detected is detected, the control device 102 displays colored lights for the abnormal parking warning and Audio is output (step 616) to guide parking lot users so that they can park normally. Figure 8 is a diagram illustrating an abnormal parking state in which a vehicle license plate is not located in the normal parking space area and an abnormal parking state in which a parking space is blocked and double parking occurs.

In step 504, if the control device 102 is a parking control edge computing device for parking status control for one or more parking spaces, it waits until the movement ends (step 600), and then the control device 102 When the parking control edge computing device in charge of controlling the entry and exit of the parking control area containing one or more parking spaces, which is in charge of (102), receives the exit information, the control device 102 determines whether there is a change from the previous image information. Determine (step 622).

The control device 102 determines whether there is a change between the previous imaging information in which no movement was detected and the current imaging information, and when a change in the imaging information is detected, it provides parking space identification information corresponding to the imaging information change area. Parking space status information recording vacancy information is created and stored (step 626).

Thereafter, the control device 102 transmits the parking space status information to the parking control edge computing device in charge of parking control for the parking management area including the corresponding parking space (step 628). Thereafter, the control device 102 outputs lighting of a color corresponding to the parking space status information through the LED lighting 112 (step 630).
