Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0019] The charging parking space assistance system provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0020] This application provides a charging parking space assistance system. Figure 1 and Figure 2 A structural block diagram of a charging parking space assistance system according to an embodiment of this application is shown. Figure 3 A schematic diagram illustrating the workflow of a charging parking space assistance system according to an embodiment of this application is shown. The charging parking space assistance system includes: At least one license plate recognition device and ground lock linkage auxiliary device are installed in the charging parking space. The auxiliary device includes a license plate recognition device 101 and a ground lock 102 that is communicatively connected to the license plate recognition device 101. The ground lock 102 is installed in the charging parking space. The license plate recognition device 101 is used to identify the vehicle license plate type and control the ground lock 102 to perform corresponding opening and closing actions, and report the parking space occupancy status of the charging parking space to the management terminal. The auxiliary device also includes a sound wave emitting unit. When the license plate recognition device 101 detects a small animal within its field of view, the sound wave emitting unit is triggered to release sound waves of a set frequency to drive away the small animal. The management terminal is used to record the occupancy status and occupancy time data of the charging spaces. The management terminal is equipped with an information interaction adapter interface, which interacts with the charging pile management system to compare and analyze the occupancy time data of the charging spaces with the actual effective usage time of the charging piles to obtain the utilization efficiency of the charging spaces.

[0021] In this embodiment, the charging parking space auxiliary system includes: at least one license plate recognition device and ground lock linkage auxiliary device installed in the charging parking space, and a management terminal. The auxiliary device includes a license plate recognition device 101 and a ground lock 102 communicatively connected to the license plate recognition device 101. The license plate recognition device 101 includes a surveillance camera and an image processing device. A "one device, two parking spaces" configuration is implemented, meaning one auxiliary device corresponds to two charging parking spaces. The management terminal communicates wirelessly with the auxiliary device.

[0022] In one embodiment, the parking lock 102 is installed on the side closest to the charging pile 103, and the length of the cable 105 is minimized at one-third of the parking space. The parking lock 102 and the cable 105 are centrally located, and the cable 105 passes around the wheel well 104. The cable 105 is waterproof and corrosion-resistant, and can be buried or not.

[0023] The license plate recognition device 101 identifies the vehicle's license plate type and controls the opening and closing of the parking lock 102, while also reporting the parking space occupancy status to the management terminal. Specifically, when a vehicle enters the charging parking area, the license plate recognition device 101 immediately starts working, quickly capturing and recognizing the vehicle's license plate. If the license plate is identified as belonging to a new energy vehicle, an unlocking command is immediately sent to the parking lock 102. Upon receiving the command, the parking lock 102 quickly lowers, allowing the new energy vehicle to smoothly enter the charging parking space. If the license plate is confirmed to be belonging to a fuel-powered vehicle, the parking lock 102 remains closed. The entire process is seamless and requires no manual intervention, greatly improving the efficiency of vehicle entry.

[0024] Integrating vehicle recognition and parking lock control functions into a single unit ensures clear internal logic and complete functionality. The parking lock control technology works in conjunction with the license plate recognition system, facilitating autonomous and automated parking space management for the license plate recognition node. Furthermore, it solves the problem of parking locks blocking new energy vehicles that need charging; any new energy vehicle can smoothly enter a charging space, providing users with a more convenient and seamless charging service and enhancing user satisfaction with charging facilities.

[0025] The auxiliary device also includes a sound wave emitting unit for emitting sound waves. The charging parking space assistance system has a small animal deterrent function. When the license plate recognition device 101 detects a small animal within its field of view, the sound wave emitting unit releases special sound waves to stimulate the animal's auditory nerves, causing it to leave the parking space and the vehicle, thus preventing potential damage to the vehicle or charging equipment. In parking lots of some older residential areas, stray cats, stray dogs, and other small animals often roam; the small animal deterrent function of this system plays an important role in ensuring the safety of charging equipment and vehicles.

[0026] The management terminal has an adaptable information interaction interface, which can exchange and compare information with the charging pile management system, so that the occupancy of charging spaces can be compared with the effective usage time of charging piles, which helps to evaluate and improve the overall utilization efficiency of charging piles.

[0027] This application provides an auxiliary system capable of independent operation and on-site control of charging parking space locks. The system comprises a management terminal and a license plate recognition device-lock linkage auxiliary device. This system can identify the license plate type of new energy vehicles, unlock the parking space lock, allow new energy vehicles to enter the charging space, and simultaneously prohibit fuel vehicles from entering. The management terminal can be adapted through an information interface to exchange and compare information with the charging pile management system, comparing the occupancy time data of each charging space with the actual effective usage time of the charging pile, which helps to evaluate and improve the utilization efficiency of the charging pile. Furthermore, the auxiliary device has a sound wave emission function that can repel small animals.

[0028] The embodiments of this application are applicable to a wide range of scenarios, not only residential communities and industrial parks, but also various places such as enterprises, institutions, hospitals and schools.

[0029] In one embodiment of this application, the management terminal is further configured to record the dwell time of the vehicle after charging is completed, and when it is determined that the dwell time exceeds a preset threshold, trigger an alert mechanism, send a departure alert, and give points rewards to vehicles that leave in a timely manner.

[0030] In this embodiment, the vehicle's dwell time after charging is completed is recorded in real time. The dwell time is calculated from the moment the charging pile stops supplying power (charging complete) until the moment the vehicle leaves the charging space. When the recorded dwell time exceeds a preset threshold, such as more than 15 minutes, an automatic reminder mechanism will be triggered, issuing light and sound reminders, or sending a departure reminder notification to the user's terminal. If the vehicle owner moves the vehicle away from the charging space within the specified time after receiving the reminder, they will receive corresponding points as a reward. These points can be used to offset charging fees, thereby incentivizing vehicle owners to move their vehicles promptly, reducing the ineffective occupation of charging spaces, and improving the utilization efficiency of charging piles.

[0031] In one embodiment of this application, the management terminal is further configured to record the cumulative number of times a vehicle stays in a charging parking space for more than a preset threshold, and when it is determined that the cumulative number exceeds the preset number, the parking space reservation priority of the vehicle is reduced.

[0032] In this embodiment, the cumulative number of times a vehicle stays in a charging space for more than a preset threshold is recorded. When the cumulative number reaches or exceeds a preset standard (such as 3 times), the priority of the vehicle in subsequent charging space reservations will be automatically reduced. This will constrain the vehicle to avoid repeatedly occupying the charging space ineffectively, improve the turnover efficiency of the parking space, and ensure the fair and efficient use of charging space resources.

[0033] In one embodiment of this application, the management terminal is further configured to receive a parking space reservation request from a user terminal, reserve a charging parking space for a target vehicle associated with the user terminal, not unlock the ground lock 102 after other vehicles arrive at the reserved charging parking space, unlock the ground lock 102 after the target vehicle arrives at the reserved charging parking space, and trigger a reminder mechanism to send a departure reminder when there is a vehicle that has finished charging but has not left the reserved charging parking space.

[0034] In this embodiment, after receiving a charging space reservation request from a user terminal, a charging space reservation procedure is processed for the target vehicle associated with that user terminal. When other unreserved vehicles arrive at the reserved charging space, the parking space lock 102 remains closed, preventing them from occupying it; when the reserved target vehicle arrives at the reserved charging space, the parking space lock 102 automatically opens, allowing the target vehicle to enter and park, thereby ensuring the reserved vehicle's exclusive right to use the charging space.

[0035] By allowing the 102 parking lock to be opened only for the target vehicle, the reserved parking space can be prevented from being occupied by other vehicles. This allows the reserved vehicle to park and charge directly upon arrival at the store, without wasting time searching for a parking space or waiting for the occupied vehicle to move, thus indirectly achieving "charging as soon as possible".

[0036] Furthermore, when a reserved charging space is occupied by a vehicle that has finished charging but has not yet left, an automatic reminder mechanism is triggered to send a notification to the owner of the lingering vehicle, informing them that the space needs to be vacated as soon as possible to ensure the availability of subsequent reserved vehicles. This effectively reduces the situation where reserved parking spaces are occupied for extended periods by vehicles that have finished charging, avoiding the problem of subsequent reserved vehicles being unable to use the space and being forced to wait. It protects the rights of those who made reservations while improving parking space turnover efficiency, allowing charging space resources to be more quickly available to the next user in need, indirectly increasing the probability that all vehicles waiting to be charged can "charge as soon as possible," making the charging service more orderly and efficient.

[0037] In addition, if a person fails to arrive at the reserved charging space within the preset time after making a reservation, the reservation will be cancelled. Failure to arrive within the reserved time will result in the charging space being "occupied". Cancelling the reservation can release the parking space in time so that other vehicles with charging needs can use it, thereby improving the turnover efficiency of parking spaces and avoiding idle resources.

[0038] In one embodiment of this application, the management terminal is further configured to record the timeout duration of a vehicle exceeding the reservation time, and when it is determined that the timeout duration exceeds a preset duration, the parking space reservation priority of the vehicle is reduced.

[0039] In this embodiment, the system records the time elapsed if a vehicle fails to arrive at a reserved charging space beyond the scheduled time. When the elapsed time reaches or exceeds a preset time threshold, such as exceeding the scheduled time by 15 minutes, the vehicle's priority for subsequent charging space reservations will be automatically lowered. Furthermore, users can be alerted, and points may even be deducted.

[0040] This effectively constrains vehicles that fail to arrive on time after making a reservation, avoiding the waste of resources caused by vehicles occupying reservation slots without being able to use them; at the same time, by adjusting priorities, vehicles that fulfill their reservations on time and arrive promptly will have better reservation opportunities, ensuring the fairness of the reservation mechanism and further improving the operational efficiency and resource utilization of the charging space reservation system.

[0041] In one embodiment of this application, the management terminal is further configured to calculate multiple efficiency indicators based on data obtained through information interaction with the charging pile management system, determine the utilization efficiency of the charging parking space based on the multiple efficiency indicators and the comparative analysis of the occupancy time data of the charging parking space and the actual effective usage time of the charging pile, and generate a dynamic efficiency label for the charging parking space; wherein, the efficiency indicators include charging start delay time, dwell time after charging is completed, and single charging amount / duration ratio.

[0042] In this embodiment, relevant data is obtained through information interaction with the charging pile management system. This data is used to calculate multiple efficiency indicators, such as charging start delay time, dwell time after charging completion, and single charging amount / duration ratio. Simultaneously, by comparing and analyzing the occupancy time data of charging spaces with the actual effective usage time of the charging piles, the utilization efficiency of each charging space is comprehensively determined, and a dynamically updatable dynamic efficiency label is generated for it. These dynamic efficiency labels include "high-efficiency parking space," "inefficient lingering parking space," and "peak-hour congestion parking space."

[0043] Dynamic efficiency labels visually present the utilization efficiency level of each charging parking space, allowing managers to quickly identify inefficient spaces, such as those with long dwell times or delayed charging start times, and develop targeted optimization measures, such as strengthening dwell reminders and troubleshooting charging pile malfunctions. It also provides users with a reference, guiding them to prioritize efficient parking spaces, reducing waiting times and unnecessary occupancy, thereby improving the overall utilization efficiency of charging parking space resources and the charging service experience.

[0044] In one embodiment of this application, the management terminal is also used to locate the cause of inefficiency based on time period data and dynamic efficiency tags of charging spaces.

[0045] In this embodiment, by combining charging-related data from different time periods, such as morning peak, evening peak, off-peak, and nighttime, as well as the dynamic efficiency tags generated for each charging parking space, the common characteristics of inefficient parking spaces under different time periods are analyzed. For example, inefficient parking spaces in a certain time period often have problems such as long lingering after charging is completed or long delay in starting charging. The specific reasons for the low utilization efficiency of charging parking spaces are accurately located.

[0046] In this way, the correlation between efficiency issues and time periods and specific indicators can be found, thereby developing more targeted optimization solutions. For example, increasing the frequency of reminders for nighttime overstays and optimizing parking space guidance for long morning peak hours can avoid blind rectification and quickly improve the overall utilization efficiency and service quality of charging parking spaces.

[0047] Multiple management systems, including access control systems (garage access control systems or parking lot access control systems) and charging pile management systems, often result in asynchronous authorization across different systems due to changes in the whitelist of one system. Different systems have different criteria for determining vehicle access permissions to charging spaces, and their whitelists are inconsistent, leading to a lack of unified and accurate criteria for determining whether a vehicle can enter a charging space. This causes problems such as: the access control system may have authorized new energy vehicles to enter, but the charging pile management system has not, causing the parking lock 102 to not lower, preventing the new energy vehicle from entering the charging space, significantly reducing user experience and charging service quality. Therefore, in one embodiment of this application, the vehicle whitelist of the charging space auxiliary system is independent of the vehicle whitelist of the access control system and the vehicle whitelist of the charging pile management system.

[0048] Changes to the access control system's whitelist do not affect the operation of the auxiliary device. The management terminal does not directly control the parking lock 102 of the charging space; instead, the auxiliary device operates autonomously, only recognizing the type of new energy vehicle license plate and controlling the opening and closing of the parking lock 102. It is completely independent of the license plate whitelists of the access control system and the charging pile management system, avoiding duplicate authorizations from multiple systems. The charging space auxiliary system does not rely on the whitelist authorization information of the access control system and the charging pile management system for vehicle access judgment, avoiding conflicts caused by inconsistent authorizations between systems. Each system is relatively independent; changes or malfunctions in other systems will not directly affect the normal operation of the charging space auxiliary system, improving its stability and maintainability.

[0049] No longer relying on the complex authorization mechanisms of access control systems and charging pile management systems, the charging parking space assistance system independently determines vehicle access, reducing the interaction and coordination between systems and making management simpler and more efficient. Because it does not depend on authorization information from other systems, the charging parking space assistance system can better adapt to different scenarios and needs, and flexibly and reliably integrate with access control systems and charging pile management systems.

[0050] In one embodiment of this application, the auxiliary device maintains a list of prohibited locks; The auxiliary device will feed back the information of vehicles that belong to the prohibited list of the parking lock to the parking lock 102 to prevent the vehicle from using the charging parking space.

[0051] In this embodiment, a new "blacklist linkage" mechanism is added, which includes vehicles that maliciously occupy parking spaces or repeatedly charge illegally in the parking lock prohibition list.

[0052] In one embodiment of this application, the ground lock prohibition list can receive a blacklist from the access control system for synchronous updates.

[0053] In this embodiment, the access control system's blacklist is synchronized unidirectionally, with only the access control system synchronizing with the parking lock blacklist, without reverse association. The core idea is to ensure that vehicles "included in the parking lock prohibition list due to malicious occupation of parking spaces or repeated unauthorized charging" are identified and prohibited from entering the access control area by the access control system. This accurately intercepts such illegal vehicles from entering the area and occupying charging spaces, while avoiding interference between the access control system's original blacklist (such as vehicles with other security violations or outstanding fees) and the parking lock prohibition list, thus ensuring the independence and targeted control of the two blacklists.

[0054] In this embodiment, an emergency manual control module is also added, allowing managers to directly operate the ground lock 102 to open and close via a mobile app or on-site control panel to deal with emergencies such as camera malfunctions and extreme weather.

[0055] In this embodiment of the application, a real-time feedback mechanism for the status of the ground lock 102 is also established. When the ground lock 102 is abnormal in opening or closing (such as jamming or not fully closed), the use of the parking space is automatically suspended and a maintenance notification is pushed.

[0056] In this embodiment of the application, a license plate blur / obstruction determination mechanism is added. When a damaged or obstructed license plate is encountered, an on-site voice prompt is automatically triggered, and a warning message is pushed to the management personnel.

[0057] This application provides a loosely coupled, highly cohesive distributed charging pile auxiliary system with a master-slave wireless communication management architecture. It includes a management terminal and multiple auxiliary devices, allowing for flexible addition or reduction of the number of auxiliary devices. The operation of these auxiliary devices is completely independent of the access control system's command and control, decoupling the systems. Each license plate recognition device can autonomously recognize new energy vehicle license plates and control the charging parking space locks, reporting to the management terminal. The management terminal records parking space occupancy. In application scenarios requiring information on available parking spaces, the management terminal reports available spaces to the access control system via an information interaction adapter interface. In composite billing parking scenarios, it reports charging parking space occupancy to the billing system. Changes and adjustments to the charging pile management system and access control system architecture do not affect the operation of the charging pile auxiliary devices.
