Description

Technical Field

[0001] The present invention relates to the technical field of vehicle guidance, and in particular to an information collection and interaction device for smart city parking management. Background Art

[0002] In the context of the booming development of smart cities today, the intelligent upgrade of urban traffic management has become a key link in improving urban operation efficiency and residents' living quality. Among them, smart city parking management, as an important part of the urban traffic system, is gradually realizing the transformation from traditional management to intelligent and refined management with the help of advanced information technology means. However, in the existing technical solutions, there are still some problems and deficiencies that need to be solved urgently. For example, a "smart city parking management information collection and interaction device" (patent number: CN202222780694.8) that has obtained national patent authorization has promoted the intelligent process of parking management to a certain extent, but there are still limitations in the comprehensiveness and accuracy of information collection.

[0003] Specifically, the core function of the parking management information collection device described in this patent focuses on detecting whether there is a vehicle parked in the parking space, that is, mainly realizing the monitoring of the occupancy status of the parking space. This function is of great significance for initially grasping the use of the parking lot and optimizing the parking space allocation strategy. However, at a deeper level of vehicle information collection, the device does not achieve the automatic recognition and collection of the license plate numbers of the vehicles in the parking space. This means that when facing vehicles parked continuously for a long time, if the parking lot management personnel need to contact the vehicle owners through license plate information for vehicle parking management (such as notifying to move the vehicle, dealing with illegal parking, etc.), they still need to rely on the traditional manual on-site confirmation method. This process not only takes time and effort, increases the management cost, but also may lead to inaccurate or missing information collection due to human factors, thus affecting the overall efficiency and effect of urban vehicle parking management. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide an information collection and interaction device for smart city parking management that can collect license plate information during the collection of parking space information.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An information collection and interaction device for smart city parking management includes an information collection module and an information interaction module. The information collection module is signal-connected to the information interaction module through wireless transmission in the cloud. The information collection module includes a vehicle detection component arranged on the parking space and a license plate information collection component arranged on one side of the parking space.

[0007] The license plate information acquisition component includes a support rod disposed on one side of the parking space. A photographing unit is provided on the support rod. The photographing unit is used to capture image data of the front or rear section of the vehicle in the parking space. The image data obtained by the photographing unit is compressed by a picture compression unit to obtain compressed data. The compressed data is wirelessly transmitted to the information interaction module through a first wireless transmission unit;

[0008] When the vehicle detection component detects that there is a vehicle in the parking space, it triggers the sequential operation of the photographing unit, the compression unit, and the first wireless transmission unit.

[0009] Preferably, the vehicle detection component includes a protection box buried in the middle of the parking space. A geomagnetic sensor and an infrared sensor are provided in the protection box.

[0010] Preferably, the vehicle detection component includes a timing unit. The timing unit is used to record the parking time of the vehicle in the parking space. When the parking time exceeds the preset parking time, the timing unit transmits the overtime data to the information interaction module through the first wireless transmission unit; The timing unit automatically resets after the vehicle drives away.

[0011] Preferably, the information interaction module includes a second wireless transmission unit, a vehicle image storage unit, a permission verification unit, a decompression unit, and an interaction unit;

[0012] The first wireless transmission unit is used to receive the compressed data transmitted by the first wireless data transmission unit. The vehicle image storage unit is used to store the compressed data received by the second wireless transmission unit. The permission verification unit is used to verify the permission of the user querying the vehicle image and activate the decompression unit after passing the verification. The decompression unit is used to decompress the compressed data and convert it into image data. The interaction unit is used to interact with the user and display the decompressed image data.

[0013] Preferably, the information interaction module further includes an alarm unit; when the second wireless transmission unit receives the overtime data, the alarm unit displays an overtime reminder on the interaction unit.

[0014] Preferably, the verification methods of the permission verification unit include passwords and dynamic passwords. The dynamic passwords are generated in real time by the mobile terminal bound to the permission verification unit.

[0015] Preferably, a supplementary lighting unit is provided at the top of the support rod. The supplementary lighting unit is provided as annularly distributed LED lamp beads. The triggering of the LED lamp beads is linked to the triggering of the vehicle detection component.

[0016] The present invention has the following beneficial effects:

[0017] 1. Precise collection of license plate information to improve information integrity: This intelligent city parking management information collection and interaction device has significant advantages in collecting parking space information. It can precisely collect license plate information, greatly improving information integrity. The information collection module in the device includes a license plate information collection component set on one side of the parking space. On the support rod of the license plate information collection component, there is a photographing unit specifically used to capture the image data of the front or rear section of the vehicle in the parking space. When the vehicle detection component detects a vehicle in the parking space, it will trigger the photographing unit to work, thereby obtaining the license plate image data of the vehicle. This design ensures that the license plate information can be timely and accurately captured at the moment the vehicle parks in the parking space, avoiding information loss caused by untimely collection or inaccurate collection range, and providing complete and reliable basic data for subsequent parking management.

[0018] 2. Efficient compression and transmission of license plate information to ensure information timeliness: After collecting the license plate image data, the device ensures the timeliness of the license plate information through an efficient compression and transmission mechanism. The image data obtained by the photographing unit will first be compressed by the picture compression unit to obtain compressed data. This compression process effectively reduces the data volume and the requirement for transmission bandwidth, enabling the data to be transmitted more quickly. Subsequently, the compressed data is wirelessly transmitted to the information interaction module through the first wireless transmission unit. The second wireless transmission unit in the information interaction module receives the compressed data transmitted by the first wireless data transmission unit and stores it in the vehicle image storage unit. This efficient compression and transmission method ensure that the license plate information can be timely transmitted from the collection end to the management end, enabling the management personnel to quickly obtain the latest parking space and vehicle information and make corresponding management decisions in a timely manner.

[0019] 3. Complete storage and convenient query of license plate information to enhance information usability: The device not only realizes the collection and transmission of license plate information but also has complete storage and convenient query functions, further enhancing the usability of the information. The vehicle image storage unit in the information interaction module is specifically used to store the received compressed data, providing a reliable storage space for the license plate information. At the same time, the permission verification unit strictly verifies the permissions of users querying vehicle images through various verification methods such as passwords and dynamic passwords. The dynamic password is generated in real time by the mobile terminal bound to the permission verification unit, increasing the security and reliability of the verification. When the user passes the permission verification, the decompression unit will decompress the compressed data and convert it into image data, and the interaction unit is used to interact with the user and display the decompressed image data. This design enables the management personnel to query the license plate information of specific vehicles at any time according to needs, providing strong support for parking management, vehicle tracking, etc.

[0020] IV. Auxiliary functions facilitate license plate information collection and improve overall performance: Some auxiliary functions in the device also provide strong support for license plate information collection, improving the overall performance. For example, a supplementary lighting unit is provided at the top of the support rod. The supplementary lighting unit is set as LED lamp beads distributed in a ring, and its triggering is linked to the triggering of the vehicle detection component. When the vehicle detection component detects a vehicle, the supplementary lighting unit will automatically light up, providing sufficient light for the photographing unit to ensure that clear license plate images can be captured under various lighting conditions, improving the accuracy and stability of license plate information collection. In addition, the timing unit in the vehicle detection component can record the parking time of the vehicle in the parking space. When the parking time exceeds the preset parking time, the overtime data will be transmitted to the information interaction module and an overtime reminder will be displayed on the interaction unit. Although this function is not directly aimed at license plate information collection, it is combined with license plate information collection to provide more comprehensive information for parking management, helping the management personnel better grasp the usage of the parking space and further improving the overall performance of the device.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] As Figures 1 to 2As shown in the figure, a smart city parking management information collection and interaction device includes an information collection module and an information interaction module. The information collection module is signal-connected to the information interaction module through wireless transmission in the cloud. The information collection module includes a vehicle detection component set on the parking space and a license plate information collection component set on one side of the parking space. The license plate information collection component includes a support rod 1 set on one side of the parking space. A photographing unit 2 is arranged on the support rod 1. The photographing unit 2 is used to capture image data of the front or rear section of the vehicle on the parking space. The image data obtained by the photographing unit 2 is compressed by a picture compression unit to obtain compressed data. The compressed data is wirelessly transmitted to the information interaction module through a first wireless transmission unit. When the vehicle detection component detects that there is a vehicle on the parking space, it triggers the sequential operation of the photographing unit 2, the compression unit, and the first wireless transmission unit.

[0027] As Figures 1 to 2 shown in the figure, the smart city parking management information collection and interaction device is composed of an information collection module and an information interaction module, and the two are signal-connected through wireless transmission in the cloud. This architecture enables the information collection module to obtain real-time data on the parking space site and transmit the data to the information interaction module wirelessly, realizing remote transmission and centralized processing of the data, providing a basis for subsequent parking management functions. As an important part of the information collection module, the vehicle detection component is set on the parking space. Its function is to monitor in real time whether there is a vehicle parked on the parking space. Once it detects that a vehicle has entered the parking space, the vehicle detection component will trigger a series of subsequent actions, playing a key role in starting the information collection process.

[0028] As Figure 1 shown in the figure, the support rod 1 provides an installation position for devices such as the photographing unit 2, ensuring that the devices can be stably set beside the parking space and work properly. It starts working after being triggered by the vehicle detection component, takes pictures of the front or rear section of the vehicle on the parking space, and obtains image data containing license plate information. The position and shooting angle of the photographing unit 2 are carefully designed to ensure that the license plate information can be clearly and accurately captured. The image data captured by the photographing unit 2 is compressed. Since the original image data is usually large, direct transmission will occupy a large amount of bandwidth and the transmission speed is slow. Through the compression process of the picture compression unit, the image data is converted into compressed data, greatly reducing the data volume and improving the data transmission efficiency. The first wireless transmission unit is responsible for wirelessly transmitting the compressed data to the information interaction module. It uses wireless communication technology to realize data interaction between the information collection module and the information interaction module, ensuring that the captured license plate information can be transmitted to the management end in a timely and accurate manner.

[0029] As Figures 1 to 2As shown in the figure, the vehicle detection component includes a protection box 3 buried in the middle of the parking space. The protection box has a transparent light-transmitting plate. A geomagnetic sensor and an infrared sensor are arranged in the protection box 3. The vehicle detection component includes a protection box 3 buried in the middle of the parking space, and a geomagnetic sensor and an infrared sensor are installed in the protection box 3. The geomagnetic sensor works based on the principle of geomagnetic field change. When a vehicle drives into the parking space, the metal body of the vehicle will change the distribution of the surrounding geomagnetic field. The geomagnetic sensor senses this change and outputs a corresponding signal. The infrared sensor uses the infrared reflection characteristic. After the vehicle enters the parking space, it will reflect the infrared rays emitted by the infrared sensor. After the sensor receives the reflected signal, it will also generate an output signal. By integrating the signals of the two sensors, it is possible to more accurately determine whether there is a vehicle in the parking space.

[0030] As Figure 2 shown in the figure, the vehicle detection component includes a timing unit. The timing unit is used to record the parking time of the vehicle in the parking space. When the parking time exceeds the preset parking time, the timing unit transmits the timeout data to the information interaction module through the first wireless transmission unit. The timing unit automatically resets after the vehicle drives away. The timing unit in the vehicle detection component works in coordination with the vehicle presence detection function. When it detects that a vehicle enters the parking space, the timing unit starts to record the parking time of the vehicle. Once the parking time exceeds the preset duration, the timing unit will transmit the timeout data to the information interaction module through the first wireless transmission unit. When the vehicle drives out of the parking space, the timing unit automatically resets to prepare for the next timing.

[0031] As Figure 2 shown in the figure, the information interaction module includes a second wireless transmission unit, a vehicle image storage unit, a permission verification unit, a decompression unit, and an interaction unit. The first wireless transmission unit is used to receive the compressed data transmitted by the first wireless data transmission unit. The vehicle image storage unit is used to store the compressed data received by the second wireless transmission unit. The permission verification unit is used to verify the permission of the user querying the vehicle image and activate the decompression unit after passing the verification. The decompression unit is used to decompress the compressed data and convert it into image data. The interaction unit is used to interact with the user and display the decompressed image data.

[0032] As Figure 2 shown in the figure, the second wireless transmission unit in the information interaction module is responsible for receiving the compressed data transmitted by the first wireless transmission unit in the information collection module. The received compressed data is stored in the vehicle image storage unit for subsequent query and management. The permission verification unit verifies the permission of the user querying the vehicle image. The verification methods include password verification and dynamic password verification. The dynamic password is generated in real time by a mobile terminal bound to the permission verification unit, which increases the security and reliability of the verification. Only users who pass the permission verification can activate the decompression unit. The decompression unit decompresses the compressed data stored in the vehicle image storage unit and converts it into image data.

[0033] As Figure 2 shown, the information interaction module further includes an alarm unit; when the second wireless transmission unit receives timeout data, the alarm unit displays a timeout reminder on the interaction unit. The interaction unit provides an interface for the user to interact with the system. The user can query the vehicle image information through the interaction unit, and the decompressed image data will be displayed on the interaction unit. At the same time, when the second wireless transmission unit receives the timeout data transmitted by the vehicle detection component, the alarm unit will be triggered to display a timeout reminder on the interaction unit, reminding the management personnel to handle the timeout parking situation in a timely manner.

[0034] As Figures 1 to 2 shown, a light supplement unit 4 is provided at the top of the support rod 1. The light supplement unit 4 is provided with LED lamp beads distributed in a ring shape, and the triggering of the LED lamp beads is linked with the triggering of the vehicle detection component. The top of the support rod 1 is provided with LED lamp beads distributed in a ring shape as the light supplement unit 4, and its triggering is linked with the triggering of the vehicle detection component. When the vehicle detection component detects that a vehicle enters the parking space, it will simultaneously trigger the light supplement unit 4, and the LED lamp beads will light up to provide sufficient light for the photographing unit 2 in the license plate information collection component. Under good lighting conditions, the photographing unit 2 can capture a clearer and more accurate license plate image, improving the quality and accuracy of license plate information collection. When the vehicle drives out of the parking space, the vehicle detection component stops triggering, and the LED lamp beads of the light supplement unit 4 go out, saving energy.

[0035] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
