Description

Roadside parking management system

This creation is about a kind of parking management, and especially about a parking space and license plate number detection device and system for roadside parking management.

By the way, the conventional parking space charging system is still in the traditional manual charging stage. In addition, most of the on-street parking grid fees still use the method of patrol toll collectors arriving at the scene regularly to issue bills. Therefore, the conventional method not only wastes manpower and material resources, but is also very inefficient. In addition, most of the current parking fees and payment methods are still to place the payment slip on the vehicle in the parking compartment. When the owner of the vehicle leaves the vehicle, the payment slip is removed and taken to a specific location toll agency for payment. , This move is not only inconvenient, but also increases the time cost. Moreover, the current parking space query is mostly limited to large department stores, stores, or large parking lots, and the management system is still only able to inform the number of parking spaces; therefore, for car owners who want to park on the road In other words, he/she does not know in advance where there are vacant parking spaces, so it takes a lot of time to detour to search for vacant parking spaces, which is quite inefficient in use.

This creation provides a parking space and license plate number detection device and system for roadside parking management, which can improve the convenience, timeliness and accuracy of roadside parking management.

This creation provides a parking space and license plate number detection device for roadside parking management The system can improve the convenience, timeliness and accuracy of on-street parking management.

The license plate number detection device used for roadside parking management in this creation is used to sense the parking time and the time of departure of the vehicle in the parking space, and set the parking space information, such as the latitude and longitude of the location, and the parking space number.

This creative roadside parking management system includes a parking space and license plate number detection device. The parking space and license plate number detection device has an imaging module and an identification module. The imaging module is used to obtain parking spaces. Information, the license plate number of the vehicle located on the parking grid. The recognition module is used to recognize the image and convert it into the corresponding license plate information, combined with the vehicle grid information; the on-street parking management system also includes a server, It has a database for managing parking information, and is connected with the parking space and the license plate number detection device. The server can accept the vehicle compartment information and the license plate sent from the parking space and the license plate number detection device Information, and update the parking information in the database accordingly, so that the user can query the parking information through a remote device to connect to the server.

Based on the above, this creation uses the parking space and license plate number detection device to obtain the roadside parking grid and the license plate number and position of the vehicle inside, and sends this set of information back to the server for calculation, storage and management, and It can be updated within a predetermined time. In this way, for parking operators, the convenience, timeliness and accuracy of their operations will be greatly improved. For car owners, they can remotely check parking information, including but not limited to parking space usage status, parking time, parking fees, etc. Furthermore, because of the camera device, it can provide more real-time parking information, especially the usage status of parking spaces, so that car owners can query the latest parking information in real time. Based on this, compared with learning skills, this creative department can improve the convenience, timeliness and accuracy of on-street parking management.

Figure 1 is a schematic diagram of a roadside parking management system 100 according to an embodiment of the present creation. In this embodiment, the roadside parking management system 100 includes a parking space and license plate number detection device 20B, 20C, and a server 30. At regular intervals, the parking space and license plate number detection device 20B, 20C is built-in. Bud module, and 14 modules for long-distance communication with Internet access, such as WIFI, LPWAN, 3G/4G/5G, etc., so you can upload parking spaces and license plate number detection device information to server 30, and receive server downloads Message. Because these parking spaces and license plate number detection devices are installed at the junction of the two car compartments, they will not be blocked from the sun by the vehicle, so they can be effectively charged by solar energy.

As shown in Figures 2, 3, and 4, the parking space and license plate number detection device 20 or 20B or 20C of this embodiment includes an upper cover 200 and a base 210, covering a 3C module 22, containing Bluetooth modules, and long-distance communication modules that can access the Internet, such as WIFI, LPWAN, 3G/4G/5G, etc., a battery 26, a solar panel 28; the solar panel 28 charges the battery 26, and the battery 26 provides a 3C module 22 power supply, a support frame is used to support the 3C module 22 and the solar panel 28, and to fix the left camera 50A and the right camera 50B. The left camera 50A of the parking space and license plate number detection device 20C faces the right, the right camera 50B faces the left, the left camera 50A is used to detect the front license plate 6 of the vehicle 9 on the second parking lot, and the right camera is used to detect the first The rear license plate 4 of the vehicle 2 on the parking bay, and the left camera 50C of the parking space and license plate number detection device 20B are used to detect the front license plate 8 of the vehicle 2 on the first parking bay. This embodiment has the advantages of the left and right camera shooting directions reversed and installed. Even if the vehicle is very close to the grid line of the parking grid, there is more distance to shoot the license plate. For example, the camera is 5-10cm away from the grid line, which can increase the capture to the front. The field of view of the license plate and the field of view of the rear license plate. Note that the angle of the camera for shooting the front license plate is about 40-50 degrees (the angle with the horizontal). The angle of the camera for shooting the rear license plate is about 55-65 degrees (the angle with the horizontal). The front license plates 6 and 8 are generally installed at a relatively stable height and relatively close to the ground, while the rear license plate 4 is generally installed at a relatively variable height and relatively far from the ground.

In addition, because it is installed on the ground, it is susceptible to being crushed by tires to affect the transparency of the shell, which in turn affects the clarity of the camera's shooting, so it is necessary to clean the shell regularly. As in the embodiment in Figure 2, a recess 202 is provided on the housing in the direction of view in front of the lens to ensure that the captured image will not be distorted or deformed. Secondly, it can prevent the shoes and tires from being directly pressed or rubbed, resulting in The field of view is blurred. However, because the dent may allow dust to accumulate easily, as long as the image obtained from the cloud is not clear, it means that the upper cover of the housing needs to be cleaned. Another embodiment is to use a protective sticker attached to the field of view in front of the lens, which needs to be replaced regularly, and the protective sticker is maintained The surface is smooth and bright; and a high-convex ring cloth protective sticker is set around to prevent the shoes and tires from directly pressing or rubbing the protective sticker.

Generally speaking, the parking space and license plate number detection device 20, taking a camera as an example, if installed on the sidewalk, it will take up space and also need to obtain the consent of the community. Thirdly, the camera is at least 2 meters away from the license plate, and the angle of shooting the license plate is too inclined, which may not be easy to recognize. If the license plate number detection device 20, taking a camera as an example, is installed on the ground, referring to Figure 4, the circular hole excavated in the road surface is first placed in an embedded box, and then the license plate number detection device 20 is embedded The top of the box is flush with the ground. It does not take up space and does not require the consent of the community. When shooting, the camera is basically in the center of the front or back of the vehicle. The shooting distance usually falls between 0.3 meters and 1.5 meters. On the other hand, because the license plate is rectangular, the font deformation is limited from top to bottom. However, if the camera is installed next to the sidewalk and the shooting angle is from right to left, the leftmost font will be very different from the rightmost font. The perspective distortion is serious, and the identification of the license plate number will increase many difficulties.

As shown in Figure 4, the parking space and license plate number detection device 20C needs to capture the images of the vehicle license plates of the first and second compartments at the same time. Therefore, two cameras 50A and 50B are required, one facing the first compartment , The other facing the second frame, the lens can generally be a standard lens, the angle of view is between 55 degrees-45 degrees, or a wide-angle lens, the angle of view is between 76 degrees-64 degrees; or the ultra-wide angle lens, the angle of view is 110 degrees- Between 84 degrees. Since the fisheye lens is close to or even greater than the angle of 180 degrees, in some embodiments, a single lens may be used to simultaneously obtain the images of the vehicle license plate of the first vehicle frame and the vehicle license plate of the second vehicle frame.

If the housing 200 of the parking space and the license plate number detection device 20 uses an arc-shaped curved surface as the upper cover, it is two centimeters above the ground, so that the lens elevation angle is about 35 degrees, and the lens center is 1.0 centimeters above the ground or parallel to the ground. If a wide-angle lens is selected, its viewing angle Is 70 degrees. If the license plate is X cm away from the camera, it can Xtan(70 deg)=2.747 X above the ground can be taken, so if X=30cm-100cm, the height limit of the license plate is from the ground to 81cm-274cm, and all images can be obtained. If you use a standard lens, the angle of view is 50 degrees, and the elevation angle of the lens is about 45 degrees. If the license plate is X cm away from the camera, the observation range is Xtan(20 deg)=0.363 X to Xtan(70 deg)=2.74 X. Similarly, if X=30cm-100cm, the height limit range of the license plate is from 11cm to 81cm-36cm Images up to 274cm are available.

Refer to Figure 5, Figure 6, and Figure 7, the parking space and license plate number detection device of this creation can also be changed in configuration as shown in Figure 5 and Figure 6, so that it can be installed between the two car compartments. On the roadside pile 45, the appearance is the same as the general roadside pile, as shown in Figure 5. Or, as shown in Figure 6, the roadside piles are not replaced, and the roadside piles are directly fixed from the inverted L-shaped part. The way the device created by this invention is installed on the roadside parking grid is shown in Figure 7, and its location is the roadside pile 45 corresponding to the boundary line of the two car grids, such as 40B and 40C. This device has 2 sets of cameras 50B and 50C which can take pictures of the front and rear car compartment and license plate at the same time. This device uses the solar battery 28 as the main power source and the internal charging and discharging battery. The camera lens angle of the license plate number before the camera can be adjusted according to the on-site installation, basically 10-30 degrees from the horizontal line, and the camera lens angle of the license plate number after the filming is 15-45 degrees from the horizontal line.

Whether the parking space and license plate number detection device 20 can be activated or not can be remotely controlled. In a preferred embodiment, the parking space and license plate number detection device 20 is activated every fixed time, such as 3-5 minutes, to perform the parking space and license plate number. Detection. Refer to Figure 4, when the vehicle 2 is parked, within 3-5 minutes, the parking space and license plate number detection devices 20B and 20C will be activated to detect the parking space and license plate number. If the camera is taken as an example, it will be the parking space and license plate number. The camera 50C of the detection device 20B is activated to capture the license plate 8 of the vehicle 2; and the camera 50A of the parking space and license plate number detection device 20C is activated to capture the license plate 4 of the vehicle 2. At the same time, the purpose of taking pictures of the front and rear license plates of the parking grid is to avoid that the parking position of the vehicle may be offset Forward or backward, the angle of view of the camera installed on the ground is insufficient, and the license plate image cannot be obtained.

The left and right cameras can stagger the shooting time so that the difference between the time of stopping and leaving and the actual time is within 1.5-2.5 minutes. Two cameras that take pictures of the same parking space only need one camera to recognize the license plate number, and then compare the color and the model to confirm the parked vehicle and the license plate number, and determine the earliest time that the vehicle parked or left. Therefore, the hourly charging, purely taking photos as the perspective of storage and inspection, will not be disputed. For the parking fee, the fee is only 1.5-2.5 minutes less, and the parking lot is also a bit cheaper, and it will not cause disputes.

Basically, if the car owner reports on their own, they don’t need to take pictures. If they don’t report on their own, they can take pictures. This can achieve a high degree of power saving. The camera equipment only needs Bluetooth to be on standby. The above-mentioned self-registration of the car owner is confirmed by using the owner to execute an APP. The owner's APP allows: When parked in the parking space, the owner’s mobile phone Bluetooth can connect to the parking space on the ground and the license plate number detection device Bluetooth or Broadcast, obtain the parking space code or upload the latitude and longitude height of the parking space to the cloud, or connect to the Internet to report, so that the cloud can obtain the license plate number of the vehicle parked in the parking space. In addition, the parking space and license plate number detection device can also obtain the vehicle license plate number by connecting with the owner's mobile phone, and then upload it to the cloud to 100% determine the parking position of the vehicle with the license plate number. The self-check-in confirmation is that the two parking spaces on the left and right of each parking space and the license plate number detection devices 20B and 20C, or 40B and 40C have received the bluetooth signal of the owner's mobile phone, so that the parking space where the owner parked can be accurately located.

In fact, the car owner APP created by this author can provide the following advantages:

1. As long as the car owner presses the button of [self-report] on the APP, the payment will be deducted directly, and the bill will be paid in points, discounts are paid, and there is no need to go to the supermarket to pay, and there is no need to get off the car to pay at the POS machine.

2. It is easy to find the car in the reverse direction. As long as you open the owner's APP, you can use GPS and mobile phone to locate yourself, and at the same time display the map of the parking lot and the location of the car. In addition to GPS, plus the latitude and longitude broadcast messages sent by each parking space and license plate number detection device via Bluetooth, the owner's APP can clearly indicate the location of the car.

The 3C module 22 of the parking space and license plate number detection device 20 includes a processor CPU, at least one image capturing module 222, an identification module 224, a memory module 226, and a communication module 228. Among them, the processor CPU is electrically connected to the above-mentioned modules 222, 224, 226, 228 for controlling each module, arithmetic processing, and transmitting data. The structure and function of each module are described as follows: The image module 222 can be a conventional camera or a photographing module, so its detailed structure will not be repeated here. The image capturing module 222 is used to obtain an image of the license plate number of the vehicle located on the parking compartment 1.

The recognition module 224 can be a known image recognition module or an edge computing AI chip, for example, it can perform image pre-processing, target position detection and capture, target area component cutting, target area The identification process such as component feature extraction, but this creation is not limited to this; further, it may include shadow processing, color conversion, and homogenization processing, etc., to further improve the identification rate. Furthermore, it can also include image recognition (such as SVM, Adaboost, Neural Network, PCA, Deep learning and other object classifiers or OCR recognition algorithms) to directly recognize the license plate number, but the above recognition methods are already learned skills , I won’t go into details here.

After the recognition is completed, the above-mentioned image can be converted into corresponding license plate information and vehicle frame information, and then transmitted to the processor CPU, and the license plate information and vehicle frame information can be directly or indirectly transmitted to the memory module 226 through the processor CPU for storage. The car compartment information here refers to the position of the car compartment where the parking sensor is located, such as latitude and longitude, or latitude and longitude. It can be set directly on the map when it is installed in the car compartment, and the number of the car compartment can also be added .

In other embodiments, the identification module 224 can also be integrated into the processor CPU. In other words, the processor itself has a built-in recognition function module.

In other derivative embodiments, the identification module 224 can also be omitted, and instead an identification module (not shown) is provided in the server 30, or an image with a built-in identification module is additionally provided. The processing server (not shown in the figure) can be identified by the server 30 itself or the image processing server will send the identified information back to the server 30, so that there is no need to modify the existing camera devices on the street or re A new camera device with a built-in identification module is additionally installed.

In other embodiments, considering that it is installed on the ground and may be affected by rain or a little bit of dust, the license plate number detection device 20 uses an arc-shaped curved surface as the upper cover with a height of two centimeters to reduce the influence of water or dust. At the same time, if the image is not clear enough, the recognition module can only perform image pre-processing, crop the image of the license plate part, and upload it directly to the server for manual recognition.

In other embodiments, considering installation on the ground, the license plate number detection device 20 uses batteries instead of mains wiring for power supply. Therefore, in order to reduce power consumption, the recognition module only performs image pre-processing, crops the image of the license plate part, and uploads it directly The server uses manual identification. For example, the image of the license plate may fall on 100 x 50 pixels. If grayscale processing is used, after compression, the data volume will only be 500 bytes. Therefore, low-power wide area communication (LPWA), such as NB-IOT, is used. CAT-M1, etc., can upload to the cloud with low power consumption.

This creation does not use additional parking sensors such as geomagnetism, infrared, ultrasonic, microwave, radar wave and other sensors, and only allows the camera to take pictures at regular intervals, for example, every five minutes, take a picture and upload it Go to the cloud for manual identification or AI automatic identification. In this way, there are two situations. In the first situation, the camera itself is a parking sensor. Even if the housing is affected by dust and cannot clearly identify the license plate, it can still effectively identify whether a car is parked, and its color and shape are still acceptable. Effective recognition, so with this creation, no additional parking sensor is needed. There may be a delay of up to five minutes in judging that the vehicle has parked, but it will not cause a complaint. If the image cannot identify the license plate, you need to send someone to take the license plate. At the same time, you can also clean the housing of the license plate number detector. The second situation is that the license plate is clearly identifiable, so the registration and deduction are directly carried out. The advantage of using a camera to shoot can reduce the possibility of theft, because it is shot every five minutes, and if there is a thief, it may also be in the lens. The built-in bluetooth communication device provides the vehicle owner with self-reporting. If the self-reporting is used, the captured image is only for archiving for future reference. The shooting time can also be resumed after half an hour to shoot once every five minutes.

In other embodiments, the camera of the parking space and license plate number detection device 20 can also be changed to an RFID reader, and the existing ETC data tags (such as RFID tags) on the vehicle are used to detect the parking space usage status. To obtain vehicle information, including but not limited to license plate numbers.

The communication module 228 can be any wireless transmission method such as WiFi, LPWAN, Zigbee, Bluetooth, 3G, 4G, 5G, etc., used to process (for example: encrypted) data processed by the processor CPU, including but not limited to license plate information , Vehicle information, date, time, etc., are sent to the server 30; in addition, in other embodiments, the communication module 228 may include a first communication module and a second communication module, respectively used to wirelessly connect to the server The device 30, or the parking space and the license plate number detecting device 20 communicate with each other. The following continues to describe the system with the server 30.

The server 30 can be installed near the parking space 1, for example, one server can be installed on one or several road sections, or it can be installed in a specific place far away. The server 30 has a database 32 for managing parking information, which includes but is not limited to parking space usage status, parking time, parking sections, parking fees, and so on.

If only the vehicle compartment information is returned, and the license plate information is indistinguishable or a specific code, it means that the vehicle on this parking compartment 1 has left and is now a vacant space. At this time, the server 30 is The parking fee of the vehicle that has left can be calculated, and the parking space usage status of the parking compartment 1 in the database 32 can be updated. Specifically, if the server 30 has received the corresponding data of the two adjacent parking spaces or the front and rear parking spaces of the specific parking space 1, but has not received the data of the specific parking space, it means the The specific parking space is now vacant, and the parking fee can be settled based on this at this time.

It can be seen from the above that the database 32 is dynamically adjusted in real time; by this, users (including but not limited to car owners) can connect to the server 30 through a remote device (computer or mobile phone) to query parking information, including But it is not limited to parking space usage status, parking time, parking fee, etc.

Similarly, the server can also output information including but not limited to license plate information, vehicle profile information, parking date, parking time, and parking section to the owner's mobile device for the owner's reference and payment.

Furthermore, in another derivative embodiment, the solution may be, for example:

1. The car owner can connect to the server 30 through App, mobile wallet, third-party payment or an existing payment site to obtain parking information, and make online or physical payment after confirming that it is correct.

2. The server 30 actively informs the owner of the car; in detail, the server 30 can learn the contact information of the owner through the parking information comparison database 32 or an external database, and then notify the owner via SMS, email, APP, etc. , The car owner can use this information to pay at the relevant site or go to a specific place to pay with the barcode in the APP; alternatively, the server 30 can notify the third-party payment operator, and the operator can confirm to the car owner or get authorization from the car owner in advance. Online payment. In addition, this action also has the effect of preventing theft; in detail, when the car owner receives the server 30 to inform his vehicle of the parking fee after the settlement of the vehicle, it means that the parking management system 100 determines that the owner's vehicle has left. If the owner does not actually leave the vehicle, it means that the vehicle may have been stolen or towed by mistake.

In addition, the server 30 in this embodiment is an existing transportation agency server, or an independent server connected to the transportation agency server, but the creation is not limited to this. In other embodiments, the server 30 can be further connected with other information servers (not shown) for data sharing; in this way, the server 30 can not only provide parking information query and notification services, but also Provide inquiries and notifications of other additional information; among them, traffic information includes but not limited to ticket information, regular vehicle inspection information, vehicle tax payment information, ETC information, etc.; other additional information includes, but is not limited to, the license plate belongs to the vehicle and the owner's name All other information.

Of course, the server 30 can also actively or passively share relevant information with other agencies, such as stolen cars, stolen cars, abnormal license plates (for example, multiple vehicles with the same license plate are registered at the same time) and other information.

In summary, this creation uses a roadside parking management system, including: a parking space and license plate number detection device, set on the ground at the junction of a first parking grid and a second parking grid, and a built-in camera for detecting the first license plate number Measure the license plate number of the vehicle on the first parking grid or whether there is a car parked, the second license plate number camera detects the license plate number of the vehicle on the second parking grid or whether there is a car parked; the camera will place the corresponding parking grid at regular intervals Vehicle license plate number detection, and upload the shooting time and shooting images; and a cloud server or block server to receive parking spaces uploaded by the first license plate number detection device and the second license plate number detection device at regular intervals Image, using manual or artificial intelligence to automatically determine whether there is a car parked, if so, determine the license plate number of the parking space, and use continuous images to record the parking time and departure time for vehicles with the same license plate number. The parking fee rate calculates the parking fee of the parking lot license plate number, and transmits the parking fee to the mobile device of the car owner via network communication, so that the mobile device of the car owner can collect the payment. For the management industry, it can reduce or even eliminate the need for patrol toll collectors, greatly reduce personnel costs, and manage each parking space accurately and effectively in real time. Can provide reservation parking service. For car owners, they can remotely check parking information, including but not limited to parking space usage status, parking time, parking fees, etc., can report and pay online independently, and can reserve parking spaces, navigation, and reverse through APP Find a car. For related agencies (such as traffic management units), this information can also be used for statistics, inspections and management. Based on this, compared to learning skills, this creative department can improve the convenience, timeliness and accuracy of on-street parking management.
