Description

Technical Field

[0001] This invention belongs to the field of prompt control technology, specifically relating to a battery full charge prompt control method for heavy truck charging stations. Background Technology

[0002] Current heavy-duty truck charging stations generally adopt a single-path charging completion reminder mechanism, with two main implementation methods. One is a local audio-visual prompt from the charging pile itself, where the charging pile emits a fixed-frequency audio-visual signal based solely on its indicator light and buzzer after the vehicle has reached a set SOC threshold. The other is a simple SMS push notification, where the charging pile sends a full-charge notification to the driver's registered mobile phone in one go. The entire notification chain is completed independently by the charging pile itself, with no unified management platform for overall scheduling, no multi-terminal hierarchical alarm logic, and no closed-loop management process for driver confirmation receipts.

[0003] The existing hardware architecture of heavy-duty truck charging stations only includes charging piles, local alarm devices for charging piles, and simple SMS gateways. It lacks a parking management platform, rest area screens, guard booth screens, patrol personnel handheld terminals, independent parking space display boards, and card reader linkage modules. Data interaction is limited to one-way output of reminder information from the charging piles; the backend cannot collect driver confirmation status in real time, nor can it dynamically adjust alarm intensity. All reminder signal frequencies and display styles remain fixed throughout the entire process.

[0004] Specifically, the shortcomings of existing technologies include: a single notification channel; the dispersed activity range of heavy-duty truck drivers, making it easy to miss notifications; heavy-duty truck charging time is generally 2-6 hours, during which drivers often go to the rest area for meals and rest, rarely staying near the charging space for extended periods; relying solely on local sound and light reminders from the charging piles, which are easily masked by vehicle idling and equipment operation at the depot; and text messages being easily blocked by silent phones or message folding, resulting in many vehicles occupying spaces for extended periods after full charging; the lack of a tiered alarm mechanism, meaning the notification intensity cannot dynamically upgrade according to the duration of occupancy; the current notification signal has a uniform intensity from triggering to vehicle removal, with no differentiated notifications for vehicles exceeding 3 minutes or 5 minutes of full charging, making it impossible for depot managers to intuitively distinguish the urgency of vehicles to be moved, and patrols lack priority guidance; and the lack of closed-loop management for driver confirmation, meaning the platform cannot determine whether the driver has received the notification. Existing technology only pushes information one-way, lacking driver ID card swiping confirmation and handheld terminal feedback processes, making it impossible for the management backend to verify the validity of the notification, leaving it only able to passively wait for drivers to move their vehicles voluntarily, resulting in a lack of effective means to control occupancy. The utilization rate of charging pile resources is low, the operating cost of the charging station is high, the construction cost and power distribution cost of heavy truck charging spaces are much higher than those of passenger car charging spaces, and the full charging of the space will directly block subsequent heavy truck charging orders. During peak hours, the station is congested with queues, the idle loss of charging equipment is aggravated, and the station's revenue and turnover efficiency are greatly reduced.

[0005] The aforementioned defects are all shortcomings of the existing single-channel, non-hierarchical, and non-closed-loop reminder architecture, which cannot adapt to the large-scale operation and management needs of large heavy-duty truck charging parking lots. A new multi-terminal hierarchical linkage and full-charge reminder control solution with confirmation receipt is urgently needed to solve these problems. Summary of the Invention

[0006] This invention aims to overcome the technical shortcomings of existing heavy-duty truck charging stations, such as a single channel for full-charge reminders, fixed alarm intensity, lack of confirmation loops, and low turnover rate of charging piles. It provides a battery full-charge reminder control method for heavy-duty truck charging stations. By building a unified parking management platform, linking various hardware terminals including independent parking space display panels, rest room central control screens, guard booth display screens, driver handheld terminals, patrol personnel handheld terminals, and card readers, a three-level differentiated alarm logic is designed, along with a closed-loop process for driver card confirmation and handheld terminal feedback. The reminder intensity and display style of each terminal are dynamically adjusted based on the vehicle's full-charge idle time, enabling multi-dimensional synchronous push of full-charge notifications. The platform verifies the driver's reception status in real time and lowers the alarm level accordingly, guiding drivers to move their vehicles promptly, reducing ineffective charging pile occupation, and improving the equipment turnover efficiency and operational revenue of large heavy-duty truck charging stations.

[0007] The present invention employs the following technical solution.

[0008] A method for controlling a fully charged battery indicator at a heavy-duty truck charging station includes: Step 1: Perform the initialization preset configuration process for the battery full charge indication control system for heavy truck charging stations; Step 2: After initializing the preset configuration process, execute the process of the parking management platform to collect charging pile operation data in real time; Step 3: After executing the process of real-time collection of charging pile operation data by the parking management platform, perform the process of determining the full charge threshold and automatically generating alarm levels; Step 4: After performing the full charge threshold determination and alarm level automatic generation process, execute the multi-terminal hierarchical synchronous push full charge reminder execution process; Step 5: After executing the multi-terminal hierarchical synchronous push full charge reminder process, a closed-loop management process for driver information receipt confirmation is carried out; Step 6: After completing the closed-loop management process for driver information reception confirmation, execute the process of dynamically downgrading the alarm level and reducing the reminder intensity.

[0009] Furthermore, the battery full charge reminder control method for heavy-duty truck charging stations operates on a battery full charge reminder control system for heavy-duty truck charging stations. The hardware architecture of the battery full charge reminder control system for heavy-duty truck charging stations includes a parking management platform, several charging piles, independent parking space display boards, a central control display screen in the rest hall, a large display screen in the guard booth, driver handheld terminals, patrol personnel handheld terminals, and driver ID card readers. The parking management platform, several charging piles, independent parking space display boards, central control display screen in the rest hall, large display screen in the guard booth, driver handheld terminals, patrol personnel handheld terminals, and driver ID card readers achieve bidirectional data interaction through the 5G or Ethernet network of the heavy-duty truck charging station.

[0010] Furthermore, step 1 specifically includes: Step 1-1: The station maintenance personnel of the heavy truck charging station log in to the parking management platform backend, complete the basic parameter preset storage, and the basic parameters are permanently stored in the database built into the parking management platform; Steps 1-2: The parking management platform completes the device binding and mapping, establishing a one-to-one association mapping relationship between each charging pile, the corresponding charging space number, the independent display board of the parking space, the camera card reader, the vehicle license plate number, the unique device ID of the driver's handheld terminal, and the handheld terminal ID of the patrol personnel, and storing it in the device association database to realize the data interconnection and binding between vehicles, parking spaces, charging piles, and various terminals. In step 1-1, the basic parameters include three categories of key configuration parameters: The first category of key configuration parameters is the charging SOC threshold parameter, which includes the custom SOC threshold for triggering a full charge warning for heavy truck batteries. The second category of key configuration parameters is the three-level alarm duration threshold parameter; The third category of key configuration parameters is the hierarchical terminal linkage parameter; In step 1-1, the three-level alarm duration threshold parameters specifically include: a primary alarm duration threshold of 3 minutes and a secondary alarm duration threshold of 5 minutes. That is, a primary alarm is triggered when the vehicle's SOC reaches the preset value for 0-3 minutes, a secondary alarm is triggered for 3-5 minutes, and a high-level alarm is triggered for more than 5 minutes. In step 1-1, the hierarchical terminal linkage parameters specifically include: For the three alarm levels—primary, intermediate, and advanced—the following parameters are preset: the flashing frequency of the parking space display board lights, the sounding frequency of the buzzer; the vibration and voice broadcasting frequency of the driver's and patrol personnel's handheld terminals; and the font color of the text on the rest room screen and the guard booth screen. All parameters are bound to the corresponding alarm level.

[0011] Furthermore, step 2 specifically includes: Step 2-1: The parking management platform sends status collection instructions to all charging piles in the station according to the preset polling cycle; Step 2-2: Each charging station collects its own operating data in real time; Steps 2-3: The charging piles will transmit all the collected data back to the parking management platform via Ethernet. The parking management platform will verify all the data, remove invalid data with garbled characters or missing fields, and store the remaining valid charging pile operation data in the real-time operation data table for continuous updating. Steps 2-4: The parking management platform monitors each vehicle charging data in the data table in real time, continuously compares the battery SOC value with the preset warning SOC threshold, and executes the full charge determination logic. In step 2-2, the collected machine operation data includes: charging pile equipment number, current charging heavy truck license plate number, corresponding parking space number, real-time SOC remaining power of the vehicle battery, charging start time, current charging status, and charging end indicator.

[0012] Furthermore, step 3 specifically includes: Step 3-1: For a single charging vehicle, if the parking management platform identifies that the on-board battery SOC is greater than or equal to the preset warning SOC threshold, it will immediately trigger a full charge reminder signal and record the current system time as the full charge trigger reference time. Step 3-2: The parking management platform calculates the time difference between the current system time and the full-charge trigger reference time in real time, and automatically classifies the alarm level based on the time difference; Step 3-3: The parking management platform generates a complete alarm data packet that binds the current parking space, vehicle, and alarm level. The data packet carries the parking space number, license plate number, current alarm level, and the audio-visual and display parameters of each terminal under the corresponding level, and is simultaneously sent to all linked terminals.

[0013] Furthermore, in step 3-2, the method for automatically classifying alarm levels based on time differences specifically includes: Time difference ∈ (0, 3 minutes): classified as a primary alarm level; Time difference ∈ (3 minutes, 5 minutes): classified as medium alarm level; Time difference > 5 minutes: classified as high alarm level.

[0014] Furthermore, step 4 specifically includes: Based on the hierarchical parameters bound in the alarm data packet, the parking management platform synchronously sends differentiated reminder instructions to the linked terminals. Each terminal executes the corresponding reminder action and performs the corresponding hierarchical control logic according to its level.

[0015] Furthermore, in step 4, the method for each terminal to execute the corresponding reminder action and the corresponding hierarchical control logic in a tiered manner specifically includes: When the alarm level is at the primary alarm level, the indicator light flashes at a frequency of 0.3Hz, the buzzer sounds intermittently at 0.3Hz, the terminal vibrates periodically at 0.3Hz, and the voice message is broadcast repeatedly: "The heavy truck in parking space XX has reached the required power level. Please move the vehicle in time." The screen's dedicated fully charged section displays the corresponding parking space number and the vehicle's complete license plate number in green font. When the alarm level is medium, the indicator light flashes at a frequency of 1Hz, the buzzer sounds intermittently at 1Hz, the terminal vibrates periodically at 1Hz, and the voice reminder to move the car when fully charged is repeatedly broadcast. The screen is fully charged and the yellow text of the partition switches to display the parking space and license plate information. When the alarm level is high, the indicator light flashes at a high frequency of 2Hz, the buzzer sounds continuously and rapidly at 2Hz, the terminal vibrates at a high frequency of 2Hz, and the voice broadcast is repeated in a loop. Pop-up notifications are continuously pushed. The screen is full of partition switching, and the parking space and license plate are displayed in red bold text and displayed at the top of the screen.

[0016] Furthermore, step 5 specifically includes: With dual confirmation channels set up, once the driver completes either confirmation action, the platform determines that the driver has received the full charge notification and automatically downgrades the alarm level. Channel 1 involves a card swipe confirmation process in the lobby, which specifically includes: Step 5-1: Install driver ID card readers at the entrance and exit of the rest hall and at the guard booth passage. The card readers are equipped with cameras to collect facial data for verification. Step 5-2: After seeing the full charge reminder on the large screen, the driver goes to the card reader to swipe his / her own driver ID card. The card reader reads the driver's identity ID and the corresponding vehicle license plate number bound to the card. Step 5-3: The card reader uploads the card reading data to the parking management platform in real time. The platform matches the vehicle alarm records in the database, identifies the full charge alarm entry corresponding to the vehicle, generates a confirmed receipt mark and stores it in the database. Channel Two involves an online confirmation process via a driver's handheld device, which specifically includes: Steps 5-11: After the driver's handheld terminal receives the graded voice and vibration reminders, a confirmation interaction button pops up on the terminal screen; Steps 5-12: The driver clicks the confirmation button on the terminal to move the car as soon as possible after receiving the message. The terminal then sends the confirmation instruction and the vehicle's bound ID back to the parking management platform. Steps 5-13: The platform receives terminal receipt information, matches the corresponding vehicle alarm data, and synchronously adds a receipt confirmation mark.

[0017] Furthermore, step 6 specifically includes: Step 6-1: After the platform detects that a vehicle alarm entry has generated a confirmed receipt flag, it immediately generates an alarm downgrade command; Step 6-2: The platform simultaneously sends downgrade control signals to the parking space display board, the two types of handheld terminals, and the two large screens. All terminals stop the current level of high-frequency reminder actions and switch to the lowest intensity static reminder mode: the indicator light on the parking space display board is always on and the buzzer stops sounding; the handheld terminals stop vibrating and broadcasting voice messages; the vehicle information on the large screens switches to a light gray static small text display and is no longer displayed at the top or flashing. Step 6-3: The platform continuously monitors the status of the vehicle charging space. If it detects that the charging pile has identified the vehicle as leaving or the charging circuit has been disconnected, the alarm record will be cleared directly, and all terminals will simultaneously delete the vehicle reminder information, thus ending the entire prompting process. If the driver does not move the vehicle for a long time after confirmation, the platform will only maintain a low-intensity static prompt and will not upgrade the audible and visual alarms, balancing the intensity of the station's reminders with the driver's experience.

[0018] The beneficial effects of the present invention are as follows, compared with the prior art: After multi-terminal synchronous reminders, the average occupancy time of charging stations is reduced, significantly shortening the waiting time for vacant charging piles. This invention progressively increases the frequency of light flashing, buzzer, and terminal vibration according to the duration of full-charge idling. The large-screen font changes from green to yellow and then to bold red, providing light reminders for minor occupancy and strong reminders for long-term occupancy. The primary alarm uses low-frequency, gentle sound and light to avoid noise interference to nearby drivers and station staff during short periods of full charge. The advanced alarm uses high-frequency, rapid sound and light, along with prominent red text, to enhance the warning effect of vehicles occupying charging piles for extended periods. Maintenance personnel can quickly identify vehicles requiring manual intervention via the large screen and handheld terminals, optimizing patrol procedures and improving the efficiency of manual management at the station. This invention provides two confirmation methods: card swiping and terminal receipt. After the driver completes confirmation, the platform immediately switches all terminals to low-intensity static prompts, turns off the buzzer, and stops high-frequency vibration and flashing lights. From an environmental perspective: the duration of sustained high-decibel noise at the charging station during peak charging periods is reduced, optimizing the station's operating environment. From a management perspective: the platform database retains every vehicle reminder confirmation record, and the station operator can export the parking space occupancy and confirmation data from the backend for optimizing station scheduling rules and driver management assessments, providing digital operational data support capabilities. The independent parking space display panel of this invention is an independent hardware unit, connected to the parking management platform via a separate communication line, and physically isolated from the charging pile control loop. Even if the charging pile's local program crashes or communication is interrupted, as long as the platform collects vehicle SOC compliance data, it can still independently drive the parking space display panel to output tiered audio-visual reminders, significantly improving the reminder system's fault tolerance and preventing operational losses due to fully charged vehicles being left unreminded and occupying spaces for extended periods caused by charging pile malfunctions. The rest hall and guard booth screens of this invention are independently divided into vehicle zones, with high-urgency vehicles highlighted in red. Management personnel can intuitively grasp the distribution and urgency levels of all occupied vehicles from the guard booth, and patrol personnel can automatically sort high-alarm vehicles using handheld terminals, eliminating the need for a full-site, space-by-space inspection. From a labor cost perspective: For heavy-duty truck charging stations of the same size, adopting this invention can reduce the number of dedicated inspection personnel, thus lowering long-term operating costs. Regarding dispatch efficiency, maintenance personnel can prioritize vehicles with high-level red alerts, specifically targeting stranded drivers, improving the efficiency of manual vehicle relocation and dispatching. After adopting this invention's multi-channel tiered reminder and confirmation closed-loop solution, the average vehicle occupancy time is significantly shortened, increasing the number of vehicles that can be charged per charging pile per day. This leads to a corresponding increase in daily charging revenue for stations of the same equipment scale, increased equipment output per unit time, and a shortened payback period for fixed investments, resulting in significant commercial operational gains.

[0019] Figure 1 This is a schematic diagram of the overall technical roadmap for the battery full charge indication control method for heavy-duty truck charging stations according to the present invention. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. The embodiments described in this application are merely some embodiments of this invention, and not all embodiments. Based on the spirit of this invention, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this invention.

[0021] like Figure 1 As shown, this invention proposes a battery full charge indication control method for heavy-duty truck charging stations, comprising the following steps: In a preferred but non-limiting embodiment of the present invention, the battery full charge reminder control method for heavy-duty truck charging stations operates on a battery full charge reminder control system for heavy-duty truck charging stations. The hardware architecture of the battery full charge reminder control system includes a parking management platform, several charging piles, independent parking space display panels, a central control display screen in the rest hall, a large display screen in the guard booth, driver handheld terminals, patrol personnel handheld terminals, and driver ID card readers. The parking management platform, charging piles, independent parking space display panels, central control display screen in the rest hall, large display screen in the guard booth, driver handheld terminals, patrol personnel handheld terminals, and driver ID card readers achieve bidirectional data interaction via the 5G or Ethernet network of the heavy-duty truck charging station. The battery full charge reminder control method for heavy-duty truck charging stations uses the parking management platform as the key execution entity. The complete control steps are divided into six processes: a preset configuration stage, a real-time charging pile data acquisition stage, a full charge threshold determination and alarm level generation stage, a multi-terminal hierarchical synchronous push reminder stage, a driver reception and confirmation closed-loop management stage, and a dynamic alarm level reduction stage. The parking management platform can be a server or a computer. The detailed implementation logic of each process is as follows: Step 1: Perform the initialization preset configuration process for the battery full charge indication control system for heavy truck charging stations; In a preferred but non-limiting embodiment of the present invention, step 1 specifically includes: Step 1-1: The station maintenance personnel of the heavy truck charging station log in to the parking management platform backend, complete the basic parameter preset storage, and the basic parameters are permanently stored in the database built into the parking management platform; In a preferred but non-limiting embodiment of the present invention, in step 1-1, the basic parameters include three types of key configuration parameters: The first category of key configuration parameters is the charging SOC threshold parameter, which includes the custom SOC threshold for triggering a full charge warning for heavy truck batteries. The station can set it to 80%, 90%, or 100% according to the operation rules. This solution prefers 80% SOC as the warning trigger benchmark value. The second category of key configuration parameters is the three-level alarm duration threshold parameter; In a preferred but non-limiting embodiment of the present invention, in step 1-1, the three-level alarm duration threshold parameters specifically include: a primary alarm duration threshold of 3 minutes and a secondary alarm duration threshold of 5 minutes. That is, a primary alarm is triggered when the vehicle's SOC reaches a preset value within 0-3 minutes, a secondary alarm is triggered within 3-5 minutes, and a high-level alarm is triggered if the SOC exceeds 5 minutes.

[0022] The third category of key configuration parameters is the hierarchical terminal linkage parameters.

[0023] In a preferred but non-limiting embodiment of the present invention, in step 1-1, the hierarchical terminal linkage parameters specifically include: For the three alarm levels—primary, intermediate, and advanced—the following parameters are preset: the flashing frequency of the parking space display board lights, the sounding frequency of the buzzer; the vibration and voice broadcasting frequency of the driver's and patrol personnel's handheld terminals; and the font color of the text on the rest room screen and the guard booth screen. All parameters are bound to the corresponding alarm level.

[0024] Steps 1-2: The parking management platform completes the device binding and mapping, establishing a one-to-one association mapping relationship between each charging pile, the corresponding charging space number, the independent display board of the parking space, the camera card reader, the vehicle license plate number, the unique device ID of the driver's handheld terminal, and the handheld terminal ID of the patrol personnel, and storing it in the device association database to realize the data interconnection and binding of vehicles, parking spaces, charging piles, and various terminals.

[0025] Step 2: After initializing the preset configuration process, execute the process of the parking management platform to collect charging pile operation data in real time; In a preferred but non-limiting embodiment of the present invention, step 2 specifically includes: Step 2-1: The parking management platform sends status collection instructions to all charging piles in the station according to the preset polling cycle (preferably once every 10 seconds); Step 2-2: Each charging station collects its own operating data in real time; In a preferred but non-limiting embodiment of the present invention, the collected machine operation data in step 2-2 includes: charging pile equipment number, current charging heavy truck license plate number, corresponding parking space number, real-time SOC remaining power of the vehicle battery, charging start time, current charging status, and charging end indicator.

[0026] Steps 2-3: The charging piles will transmit all the collected data back to the parking management platform via Ethernet. The parking management platform will verify all the data, remove invalid data with garbled characters or missing fields, and store the remaining valid charging pile operation data in the real-time operation data table for continuous updating. Steps 2-4: The parking management platform monitors each vehicle charging data in the data table in real time, continuously compares the battery SOC value with the preset warning SOC threshold, and executes the full charge determination logic.

[0027] Step 3: After executing the process of real-time collection of charging pile operation data by the parking management platform, perform the process of determining the full charge threshold and automatically generating alarm levels; In a preferred but non-limiting embodiment of the present invention, step 3 specifically includes: Step 3-1: For a single charging vehicle, if the parking management platform identifies that the on-board battery SOC is greater than or equal to the preset warning SOC threshold, it will immediately trigger a full charge reminder signal and record the current system time as the full charge trigger reference time. Step 3-2: The parking management platform calculates the time difference between the current system time and the full-charge trigger reference time in real time, and automatically classifies the alarm level based on the time difference; In a preferred but non-limiting embodiment of the present invention, the method for automatically classifying alarm levels based on time differences in step 3-2 specifically includes: Time difference ∈ (0, 3 minutes): classified as a primary alarm level; Time difference ∈ (3 minutes, 5 minutes): classified as medium alarm level; Time difference > 5 minutes: classified as high alarm level.

[0028] Step 3-3: The parking management platform generates a complete alarm data packet that binds the current parking space, vehicle, and alarm level. The data packet carries the parking space number, license plate number, current alarm level, and the audio-visual and display parameters of each terminal under the corresponding level, and is simultaneously sent to all linked terminals.

[0029] Step 4: After performing the full charge threshold determination and alarm level automatic generation process, execute the multi-terminal hierarchical synchronous push full charge reminder execution process; In a preferred but non-limiting embodiment of the present invention, step 4 specifically includes: Based on the hierarchical parameters bound in the alarm data packet, the parking management platform synchronously sends differentiated reminder instructions to the linked terminals. Each terminal executes the corresponding reminder action and performs the corresponding hierarchical control logic according to its level.

[0030] In a preferred but non-limiting embodiment of the present invention, the method for each terminal to execute a corresponding reminder action and to execute corresponding hierarchical control logic in step 4 specifically includes: When the alarm level is at the primary alarm level, the indicator light flashes at a frequency of 0.3Hz, the buzzer sounds intermittently at 0.3Hz, the terminal vibrates periodically at 0.3Hz, and the voice message is broadcast repeatedly: "The heavy truck in parking space XX has reached the required power level. Please move the vehicle in time." The screen's dedicated fully charged section displays the corresponding parking space number and the vehicle's complete license plate number in green font. When the alarm level is medium, the indicator light flashes at a frequency of 1Hz, the buzzer sounds intermittently at 1Hz, the terminal vibrates periodically at 1Hz, and the voice reminder to move the car when fully charged is repeatedly broadcast. The screen is fully charged and the yellow text of the partition switches to display the parking space and license plate information. When the alarm level is high, the indicator light flashes at a high frequency of 2Hz, the buzzer sounds continuously and rapidly at 2Hz, the terminal vibrates at a high frequency of 2Hz, and the voice broadcast is repeated in a loop. Pop-up notifications are continuously pushed. The screen is full of partition switching, and the parking space and license plate are displayed in red bold text and displayed at the top of the screen.

[0031] It should be noted that the linked terminals include: The parking space has an independent display panel, which is installed at the front of each heavy truck charging parking space. It is equipped with an independent LED indicator and an active buzzer. It is not controlled by the alarm device of the charging pile itself. It receives frequency instructions from the platform and outputs sound and light reminders independently, which is different from the alarm built into the charging pile. It reminds people passing by the station at close range. The driver handheld terminal is equipped with a dedicated handheld terminal for each heavy truck driver, which is bound to the driver's identity ID and frequently used vehicle. The platform only pushes exclusive reminders to the corresponding vehicle's bound terminal to avoid irrelevant messages from interfering with other drivers. Patrol personnel are equipped with handheld terminals, which are uniformly provided to the station's operation and maintenance patrol personnel. All information on high-alarm vehicles is pushed out simultaneously, making it easier for patrol personnel to prioritize the location of high-priority occupied vehicles and find the drivers. The central control screen in the rest hall and the display screen in the guard booth are divided into fixed zones. Only the information of vehicles that have reached the SOC warning threshold is displayed. Vehicles that have not reached the SOC threshold do not occupy the screen display resources. The font color changes with the alarm level to intuitively distinguish the urgency of the occupation. Drivers and guards in the rest hall and guard booth can quickly identify vehicles that need to be moved.

[0032] Step 5: After executing the multi-terminal hierarchical synchronous push full charge reminder process, a closed-loop management process for driver information receipt confirmation is carried out; In a preferred but non-limiting embodiment of the present invention, step 5 specifically includes: This invention establishes a dual confirmation channel. Once the driver completes either confirmation operation, the platform determines that the driver has received the full charge notification and automatically lowers the alarm level. The dual confirmation channels operate in parallel without conflict. Channel 1 involves a card swipe confirmation process in the lobby, which specifically includes: Step 5-1: Install driver ID card readers at the entrance and exit of the rest hall and at the guard booth passage. The card readers are equipped with cameras to collect facial data for verification. Step 5-2: After seeing the full charge reminder on the large screen, the driver goes to the card reader to swipe his / her own driver ID card. The card reader reads the driver's identity ID and the corresponding vehicle license plate number bound to the card. Step 5-3: The card reader uploads the card reading data to the parking management platform in real time. The platform matches the vehicle alarm records in the database, identifies the full charge alarm entry corresponding to the vehicle, generates a confirmed receipt mark and stores it in the database. Channel Two involves an online confirmation process via a driver's handheld device, which specifically includes: Steps 5-11: After the driver's handheld terminal receives the graded voice and vibration reminders, a confirmation interaction button pops up on the terminal screen; Steps 5-12: The driver clicks the confirmation button on the terminal to move the car as soon as possible after receiving the message. The terminal then sends the confirmation instruction and the vehicle's bound ID back to the parking management platform. Steps 5-13: The platform receives terminal receipt information, matches the corresponding vehicle alarm data, and synchronously adds a receipt confirmation mark.

[0033] Step 6: After completing the closed-loop management process for driver information reception confirmation, execute the process of dynamically downgrading the alarm level and reducing the reminder intensity.

[0034] In a preferred but non-limiting embodiment of the present invention, step 6 specifically includes: Step 6-1: After the platform detects that a vehicle alarm entry has generated a confirmed receipt flag, it immediately generates an alarm downgrade command; Step 6-2: The platform simultaneously sends downgrade control signals to the parking space display board, the two types of handheld terminals, and the two large screens. All terminals stop the current level of high-frequency reminder actions and switch to the lowest intensity static reminder mode: the indicator light on the parking space display board is always on and the buzzer stops sounding; the handheld terminals stop vibrating and broadcasting voice messages; the vehicle information on the large screens switches to a light gray static small text display and is no longer displayed at the top or flashing. Step 6-3: The platform continuously monitors the status of the vehicle charging space. If it detects that the charging pile has identified the vehicle as leaving or the charging circuit has been disconnected, the alarm record will be cleared directly, and all terminals will simultaneously delete the vehicle reminder information, thus ending the entire prompting process. If the driver does not move the vehicle for a long time after confirmation, the platform will only maintain a low-intensity static prompt and will not upgrade the audible and visual alarms, balancing the intensity of the station's reminders with the driver's experience.

[0035] It should be noted that the specifications for the site's hardware layout are as follows: Each parking space has an independent display panel installed 1.5m high on the pillar directly in front of each heavy-duty truck charging space, with no visual obstruction, and the flashing lights can be clearly observed from the station aisles and patrol routes. The central control display screen in the rest hall is installed on the wall opposite the entrance and exit of the hall reception desk, so that all resting drivers can look up and see it. The display screen in the guard booth is installed directly in front of the guard booth's operating position, allowing the on-duty personnel to monitor vehicles occupying parking spaces in real time. Driver ID card readers are placed in the entrance and exit of the rest hall and at the entrance of the main guard booth of the station, and are equipped with high-definition cameras to complete secondary identity verification to prevent unauthorized card swiping. The handheld terminal for patrol personnel supports full signal coverage of the station and simultaneously receives alarm data of all levels. Vehicles with high alarms are automatically placed at the top of the terminal list, making it convenient for maintenance personnel to manually intervene and find the drivers.

[0036] This invention can replace the trigger threshold of 80% with 90%, 95%, and 100% full charge states, adjusting only the judgment criteria. The core logic of three-level classification, multi-terminal linkage, and closed-loop confirmation remains unchanged. The primary and intermediate alarm boundaries of 3 minutes and 5 minutes can be adjusted to 2 minutes / 4 minutes and 5 minutes / 10 minutes according to the station traffic flow, while the hierarchical control architecture remains unchanged. The 0.3Hz, 1Hz, and 2Hz sound and light vibration frequencies can be amplified or reduced synchronously, and the hierarchical differentiated reminder mechanism remains the core innovation of this invention.

[0037] This invention uses a parking management platform as its core, linking multiple terminals—independent display panels for parking spaces, large screens in rest areas, large screens in guard booths, driver handheld terminals, and patrol handheld terminals—to simultaneously issue differentiated full-charge reminders. This breaks through the limitations of existing technologies that only provide reminders from a single charging station device, covering all driver activity scenarios through multiple channels. Based on the duration a heavy truck remains stationary after being fully charged, it categorizes alarm levels into primary, intermediate, and advanced levels. Different levels correspond to different sound and light frequencies and screen font color display logic for each terminal, enabling the reminder intensity to dynamically upgrade with the duration of occupancy. The system allows the parking lot to intuitively distinguish the urgent priority of moving vehicles. It also features dual functionality: offline confirmation via driver ID card swiping and online receipt via handheld terminal. The platform confirms a closed-loop mechanism, automatically reducing the alarm intensity of all terminals after receiving a confirmation signal from the driver, thus addressing the shortcomings of existing technologies that lack feedback and control mechanisms. Each parking space is equipped with an independent audio-visual display board, separate from the charging pile's alarm device. This board independently receives hierarchical control commands from the platform, is not limited by the charging pile's own program, and provides tiered audio-visual alerts at close range, compensating for the problem of charging pile alarms being masked by noise. Dedicated large screens in rest areas and guard booths display fully charged vehicles, switching font colors according to alarm levels and highlighting high-urgency vehicles at the top, allowing resting drivers and station management personnel to quickly identify vehicles awaiting relocation and assisting in accurate dispatching during manual patrols.

Pop-up notifications are continuously pushed. The screen is full of partition switching, and the parking space and license plate are displayed in red bold text and displayed at the top of the screen.

9. The battery full charge indication control method for heavy-duty truck charging stations according to claim 8, characterized in that, Step 5 specifically includes: With dual confirmation channels set up, once the driver completes either confirmation action, the platform determines that the driver has received the full charge notification and automatically downgrades the alarm level. Channel 1 involves a card swipe confirmation process in the lobby, which specifically includes: Step 5-1: Install driver ID card readers at the entrance and exit of the rest hall and at the guard booth passage. The card readers are equipped with cameras to collect facial data for verification. Step 5-2: After seeing the full charge reminder on the large screen, the driver goes to the card reader to swipe his / her own driver ID card. The card reader reads the driver's identity ID and the corresponding vehicle license plate number bound to the card. Step 5-3: The card reader uploads the card reading data to the parking management platform in real time. The platform matches the vehicle alarm records in the database, identifies the full charge alarm entry corresponding to the vehicle, generates a confirmed receipt mark and stores it in the database. Channel Two involves an online confirmation process via a driver's handheld device, which specifically includes: Steps 5-11: After the driver's handheld terminal receives the graded voice and vibration reminders, a confirmation interaction button pops up on the terminal screen; Steps 5-12: The driver clicks the confirmation button on the terminal to move the car as soon as possible after receiving the message. The terminal then sends the confirmation instruction and the vehicle's bound ID back to the parking management platform. Steps 5-13: The platform receives terminal receipt information, matches the corresponding vehicle alarm data, and synchronously adds a receipt confirmation mark.

10. The battery full charge indication control method for heavy-duty truck charging stations according to claim 9, characterized in that, Step 6 specifically includes: Step 6-1: After the platform detects that a vehicle alarm entry has generated a confirmed receipt flag, it immediately generates an alarm downgrade command; Step 6-2: The platform simultaneously sends downgrade control signals to the parking space display board, the two types of handheld terminals, and the two large screens. All terminals stop the current level of high-frequency reminder actions and switch to the lowest intensity static reminder mode: the indicator light on the parking space display board is always on and the buzzer stops sounding; the handheld terminals stop vibrating and broadcasting voice messages; the vehicle information on the large screens switches to a light gray static small text display and is no longer displayed at the top or flashing. Step 6-3: The platform continuously monitors the status of the vehicle charging space. If it detects that the charging pile has identified the vehicle as leaving or the charging circuit has been disconnected, the alarm record will be cleared directly, and all terminals will simultaneously delete the vehicle reminder information, thus ending the entire prompting process. If the driver does not move the vehicle for a long time after confirmation, the platform will only maintain a low-intensity static prompt and will not upgrade the audible and visual alarms, balancing the intensity of the station's reminders with the driver's experience.
