Description

[0001] Technical Field This application relates to the field of electronic digital data technology, specifically to a method for controlling the display of drone delivery information based on a low-power e-ink screen. Background Technology

[0002] With the rapid development of drone logistics technology, drone delivery boxes, as key components for cargo carrying and transportation, have been widely used in scenarios such as instant retail, medical emergency, and same-city delivery. Currently, drone delivery boxes on the market mainly focus on structural protection performance, such as drop resistance, waterproofing and lightweight design. Some high-end products integrate GPS positioning or Bluetooth communication modules to achieve real-time location tracking of the delivery box. Existing drone delivery boxes still have significant shortcomings in terms of information interaction, energy consumption control, and environmental adaptability. Specifically, they lack information interaction capabilities, lack visual information display functions, and recipients cannot directly obtain key information such as order number, goods type, and estimated delivery time, and must rely on mobile apps to query them. When the mobile phone signal is weak or the battery is low, it can easily lead to problems such as anxiety while waiting to receive the package and misdelivery of goods; the additional display module consumes too much power. If the delivery box integrates a traditional LCD or OLED display, it will continuously consume the drone's battery power; although there are drone scheduling and energy consumption optimization solutions in the existing technology, such as PID control based on PSO algorithm and variable step size frequency scanning, none of them involve low power information display and adaptive status update of the delivery box itself. Therefore, there is an urgent need for a drone delivery control method that can achieve visualized delivery information, strong environmental adaptability, and support real-time linkage while ensuring battery life.

[0003] Summary of the Invention In order to solve the problems existing in the prior art, the purpose of this application is to provide a method for controlling the display of drone delivery information based on a low-power e-ink screen.

[0004] The method for controlling the display of drone delivery information based on a low-power e-ink screen as described in this application includes the following steps: S101. Receive order information via wireless communication module, including order number, goods type and estimated delivery time; S102, The main control module controls the low-power e-ink display module to perform a full-screen refresh to display the order information; S103. During delivery, the drone flight control system receives real-time status information via the wireless communication module, and the main control module controls the e-ink screen to perform partial refresh to update the estimated delivery time. S104. The loading or unloading status of the goods is detected by the gravity sensor. When the goods are removed, a status update signal is triggered. S105. The main control module controls the e-ink screen to update the delivery status and sends delivery completion information to the dispatch center via the wireless communication module. S106. In the empty state, the main control module controls the e-ink screen to enter sleep mode, displaying static text and reducing power consumption.

[0005] Furthermore, in step S101, wireless communication technology acquires order data including order number, goods category and arrival time, forms a structured record, performs uniqueness verification on the order number, marks duplicate numbers and generates an anomaly list, backtracks the original log to correct the data, classifies the goods according to preset rules and determines the processing priority based on the corrected information, generates a time sorting list by combining arrival time prediction, optimizes the delivery sequence to meet time limit requirements, generates delivery task allocation instructions, forms an execution plan, and synchronously updates the equipment status.

[0006] Furthermore, in step S102, the main control module extracts order information from the storage unit, forms a complete information set, drives the display module to parse and determine the display layout according to the preset format, and sends a full-screen update command to the e-ink screen to complete the initial presentation of the information. If a display abnormality is detected, the abnormal area is located and it is determined whether to perform a partial refresh. The display module reloads the abnormal area to correct the screen and obtain a complete display effect. The main control module records the screen status and updates the presentation log to confirm that the display operation is complete.

[0007] Furthermore, in step S103, the wireless communication module monitors the drone's status, obtains real-time data from the flight control system to determine the flight progress, and the main control module calculates the latest estimated delivery time based on preset rules. It then generates a display command to drive the e-ink screen to partially refresh the time area. If there is a deviation in the display after the refresh, the position of the deviation is detected and it is determined whether a second refresh is needed. A targeted command is then generated to perform a second update until the display is accurate. The screen status is recorded and the display log is updated to ensure that the delivery information is consistent with the real-time data, thus forming a complete business closed loop.

[0008] Furthermore, in step S104, the gravity sensor continuously monitors changes in the weight of the goods. When the weight drops below a preset threshold, it is determined that the goods have been unloaded and a status change signal is generated. The signal is sent to the central processing unit via the transmission module. After receiving confirmation, the internal clock records the timestamp and generates a complete log entry by combining it with historical data. If data anomalies are found, a backup verification mechanism is activated to compare the data to confirm the accuracy of the status. The confirmed status is updated to the delivery management platform through data synchronization to ensure consistency of system status information.

[0009] Furthermore, in step S105, the main control module acquires and categorizes the latest delivery data, drives the e-ink screen to update to the corresponding state, generates complete delivery completion confirmation information, packages it and sends it to the dispatch center. After successful transmission feedback, the interaction time point is recorded and combined with historical records to form a complete status change log. The data synchronization mechanism successfully uploads the log to the dispatch center storage unit, completing the entire process.

[0010] Furthermore, in step S106, when the device is in an empty state, the main control module determines that it meets the conditions and generates a sleep command, drives the e-ink screen to switch the displayed content to fixed text, monitors the screen power consumption, and adjusts the parameters to reduce it to the target range if it exceeds the threshold. The status change and time point are recorded as a complete log, and the synchronization mechanism transmits it to the background storage. Based on the confirmation of saving, a status monitoring report is generated, and combined with historical data, a complete status information of the device operation is formed.

[0011] The drone delivery information display control method based on low-power e-ink screen described in this application has the advantages of achieving extremely low power consumption operation, significantly extending the drone's battery life, using e-ink screen as the display module, the power consumption is close to zero when displaying statically, the power consumption of a single partial refresh is only 0.05mAh, the average daily total power consumption does not exceed 2mAh, accounting for less than 1% of the drone's total power consumption; Compared to traditional LCD displays, it can increase the drone's single-charge range by 8-12 kilometers, fundamentally solving the technical problem of "high power consumption of the display leading to shortened flight time"; With strong environmental adaptability and improved outdoor information visibility, the e-ink screen has a viewing angle of ≥178° and a strong light contrast ratio of ≥12:1. The information recognition rate is over 95% in outdoor sunny conditions, effectively overcoming the problems of reflection and poor visibility of LCD / OLED screens under strong light. To build an information linkage mechanism and improve delivery efficiency and user experience, the delivery box is synchronized with the drone flight control system and dispatch center in real time by integrating Bluetooth 5.0 and LoRa dual-mode communication, with an update delay of no more than 10 seconds. It supports intelligent sleep and status feedback, has a high degree of system automation, automatically enters sleep mode when the box is empty, and the standby power consumption of the whole machine is less than 3μA / h, supporting more than 30 days of long-term standby. Meanwhile, the system can automatically report the delivery completion status through the wireless communication module, realizing closed-loop management and further improving the system's intelligence and reliability.

Figure 1 ; Figure 2 This application describes a method for controlling the display of drone delivery information based on a low-power e-ink screen. Figure 2 . Detailed Implementation

[0013] like Figures 1-2 As shown, the method for controlling the display of drone delivery information based on a low-power e-ink screen according to this application includes: like Figures 1-2 As shown, S101, receive order information via wireless communication module, including order number, goods type and estimated delivery time.

[0014] Furthermore, in step S101, order-related data, including order number, goods category and arrival time, is obtained from the module device through wireless communication technology to complete the preliminary information collection and obtain a structured order record; Based on the structured order records, a data parsing tool is used to verify the uniqueness of the order numbers. If duplicate numbers are found, an anomaly flag is triggered, and a list of abnormal orders is determined. For abnormal order lists, the receiving process is traced back through the transmission method to obtain the original data log, determine whether there is data loss or error, and obtain the corrected order information; Extract the goods categories from the revised order information, group the goods according to the preset classification rules, and determine the processing priority of each group of goods; Based on the processing priority of each group of goods and combined with the arrival time prediction, a time sorting list is generated to determine whether the delivery time limit requirement is met, and an optimized delivery sequence is obtained. By optimizing the delivery sequence and combining it with the order management mechanism, delivery task allocation instructions are generated, and the final delivery execution plan is determined. For the delivery execution plan, the status records in the information content update module device are used to complete the real-time synchronization of order data and obtain the latest business status feedback.

[0015] Specifically, in step S101, during the process of receiving order information through the wireless communication module, the system first establishes a connection with the remote server using the wireless communication protocol (4G or 5G network) and receives an encrypted data packet containing the order number, goods type and estimated delivery time. Assuming the received data packet is 2.5KB in size, the system will decrypt the data using the AES-128 encryption algorithm. The decryption process involves dividing the data packet into 128-bit data blocks and performing 16 rounds of iterative calculations using a preset key to ensure data integrity. The decrypted data will display the order number as "ORD20231001", the goods type as "electronic products", and the estimated delivery time as "October 2, 2023, 14:00". The system will verify the integrity of the data using the built-in check algorithm (CRC32), calculate the check value and compare it with the check code at the end of the data packet. If the check value matches, it is confirmed that the data has not been tampered with. Otherwise, the system will automatically send a retransmission request to the server. The maximum number of retransmissions is set to 3. If it still fails, the system will log and trigger an alarm mechanism. The system will store the parsed order information in the local database and insert data using SQL statements, such as "INSERTINTOorders(orderid,goodstype,eta)VALUES('ORD20231001','electronics','2023-10-02,14:00')". It will also compare and analyze the difference between the estimated delivery time and the current system time by timestamp. Assuming the current time is "October 1, 2023, 10:00", the remaining time is calculated to be 28 hours. The system will automatically adjust the priority of subsequent logistics scheduling based on this time difference. If the remaining time is less than 24 hours, the priority will be raised to "urgent". The system will also link order information with the inventory management system and query inventory status through the API interface. Assuming that the inventory of electronic products is 50 units, the system will automatically determine whether it meets the order demand. If the inventory is insufficient, the replenishment process will be triggered. The replenishment quantity calculation formula is: replenishment quantity = demand - current inventory + safety stock. The safety stock is set to 10 units to ensure a smooth supply chain. Through a series of automated processes, order information forms a complete closed loop from receipt and analysis to business linkage, ensuring efficiency and accuracy.

[0016] In one embodiment, after receiving the order information via the wireless communication module in step S101, the system calculates the remaining time to determine the delivery priority, using the following formula:

[0017] Where ΔT: Remaining time (unit: hours), representing the time difference from the current time to the estimated delivery time; T eta Estimated delivery time (in hours), obtained from order information; T current Current system time (unit: hours); Priority decision: if ΔT <T threshold (e.g., T) threshold If the delivery time is 24 hours, the delivery priority is set to "urgent"; otherwise, it is set to "normal".

[0018] like Figures 1-2 As shown in Figure S102, the main control module controls the low-power e-ink display module to perform a full-screen refresh to display the order information.

[0019] Furthermore, in step S102, the order information content to be displayed is obtained through the main control module, and relevant fields are extracted from the storage unit using a preset data reading mechanism to obtain a complete set of order information; Based on the complete set of order information, the driver display module performs data parsing and processing, arranges the information content according to the preset display format, and determines the final display layout style; For the final display layout style, the main control module sends a full-screen update command to the e-ink screen to trigger the screen refresh operation and obtain the initial display result of the information content; If there are display abnormalities in the initial results, the main control module will detect the refresh status of the ink screen, obtain the location information of the abnormal area, and determine whether the partial refresh operation needs to be re-executed. Based on the judgment result of the partial refresh operation, the information content of the abnormal area is reloaded through the display module to complete the screen refresh correction process and obtain the complete display effect. To ensure a complete display effect, the main control module records the current state of the e-ink screen, and a data synchronization mechanism is used to update the log records of information presentation to determine the final completion status of the display operation.

[0020] Specifically, in step S102, the entire process of the main control module controlling the low-power e-ink display module to perform a full-screen refresh to display order information is achieved through a series of automated information technologies; After receiving the order data, the main control module will automatically parse the information content, extract key fields such as the order number "ORD20231005", the goods category "household appliances" and the estimated delivery time "October 3, 2023, 16:00", and convert this data into the format required for e-ink display. Assuming the converted data packet size is 1.2KB, the system will calculate the display layout based on the e-ink resolution of 1920x1080, ensuring that the font size is 16 pixels and the line spacing is 20 pixels to optimize the visual presentation. The system determines the full-screen refresh frequency through a built-in refresh algorithm. Assuming the minimum power refresh cycle supported by the e-ink screen is 5 seconds, the algorithm will dynamically adjust the refresh power consumption based on the current battery status (assuming the remaining battery is 75%). The calculation formula is: power adjustment value = base power consumption 0.5W x (1 - battery percentage 0.75), resulting in an adjusted power consumption of 0.125W, ensuring energy saving. The main control module sends a refresh command to the e-ink screen. The command includes data rendering parameters. The system will analyze the rendering time. Assuming the rendering time is 3.2 seconds, if it exceeds the preset threshold of 3 seconds, the system will automatically optimize the data compression rate, increasing it from the initial 50% to 60% to reduce the transmission burden. After the e-ink screen completes the refresh, the system will automatically detect the display integrity and compare the matching degree between the original data and the displayed data through a pixel verification algorithm. If the matching degree is 98.5%, which is higher than the threshold of 95%, the display is confirmed to be correct; otherwise, a local redraw mechanism is triggered. To form a closed business loop, the system will also associate the display status with the order tracking system and upload display logs through an internal interface. Assuming the log size is 0.8KB, if the upload fails, it will be cached locally and retried after the network recovers to ensure information synchronization. Through automated processes, from data parsing to display refresh and status feedback, a tight logical chain is formed to ensure the accurate presentation of order information.

[0021] In one embodiment, in step S102, the main control module controls the low-power e-ink display module to perform a full-screen refresh. During the full-screen refresh, the system dynamically adjusts power consumption based on battery level to optimize energy consumption. The calculation formula is as follows:

[0022] P adj Adjusted power consumption (unit: watts), used for actual refresh operations; P base Base power consumption (unit: watts), for example, the typical power consumption of full-screen refresh (0.5W); B: Battery charge percentage (dimensionless), ranging from 0 to 1 (0.75 represents 75% charge).

[0023] like Figures 1-2 As shown in S103, during delivery, the real-time status information of the drone flight control system is received through the wireless communication module, and the main control module controls the e-ink screen to perform partial refresh and update the estimated delivery time.

[0024] Furthermore, in step S103, the drone's status during the delivery process is continuously monitored through the wireless communication module, real-time status data is obtained from the flight control system, and the current flight progress information is determined. Based on the acquired flight progress information, the main control module processes the status data and, in conjunction with preset time estimation rules, calculates the latest estimated time to obtain the updated delivery information. In response to the updated delivery information, the main control module generates corresponding display content instructions, drives the e-ink screen to perform a partial refresh operation for the expected time area, and determines the update result of the display interface; If the display update of the e-ink screen is off after the partial refresh operation is completed, the main control module will detect the refresh status of the display area, obtain the specific location of the deviation, and determine whether the refresh mechanism needs to be triggered again. If it is determined that the refresh mechanism needs to be triggered again, the main control module generates a targeted refresh command based on the deviation position, and performs a secondary update on the specified area through the e-ink screen to obtain the corrected display content; After obtaining the corrected display content, the main control module records the current state of the ink screen, updates the display log during the delivery process using a data synchronization mechanism, and determines the final display operation record. By following the steps above, we can ensure that the delivery information during the delivery process is consistent with the real-time status data, thus forming a complete business processing flow.

[0025] Specifically, in step S103, during the delivery process, the real-time status information of the UAV flight control system is received through the wireless communication module, and the main control module controls the e-ink screen to perform partial refresh to update the estimated delivery time. The entire process is achieved through automation technology. The system acquires real-time flight data from the UAV flight control system via a wireless communication module at a data acquisition frequency of once per minute. For example, the current flight speed is 15.5 m / s, the remaining flight distance is 3.2 km, and the ambient wind speed is 2.8 m / s. The system automatically calculates the estimated delivery time using the formula: Estimated time = Remaining distance / Flight speed + Wind speed drag correction value of 0.1 minutes, resulting in an estimated delivery time of 13.3 minutes. The main control module packages the updated time data into a small data packet of 0.5KB and adjusts the layout of the local refresh area of ​​the e-ink screen. Assuming that the local refresh area is 200x100 pixels at the top of the screen, the system automatically selects the minimum refresh range to reduce power consumption. The analysis shows that the refresh area accounts for only 9.3% of the total screen area, which meets the requirement of energy saving threshold below 10%. The system determines the update frequency through a partial refresh algorithm. Assuming the minimum refresh interval is 2 seconds and considering the current network latency of 0.3 seconds, the system dynamically adjusts the refresh command sending interval to 2.2 seconds to ensure data transmission stability. After the refresh is complete, the system automatically verifies the accuracy of the update of the local display area and calculates the consistency ratio of the data before and after the update through the data verification mechanism. If the consistency is 97.8%, which is higher than the preset threshold of 96%, the update is confirmed to be successful; otherwise, the retransmission mechanism is triggered. To ensure a closed-loop business process, the system will update the status and connect with the delivery monitoring platform to generate a status report data packet of 0.4KB in size. This packet will be uploaded to the cloud via an encrypted channel. If the network is interrupted, the data will be automatically stored in the local cache and re-uploaded after the signal is restored, ensuring that the delivery information is synchronized in real time. Through the above process, from receiving the status to partial refreshing and then to status feedback, a tight logical chain is formed to ensure the timely updating of delivery information.

[0026] In one embodiment, during delivery in step S103, the main control module controls the e-ink screen to perform a partial refresh to update the estimated delivery time. The system calculates the new estimated delivery time based on the drone's real-time status (remaining distance, flight speed, wind speed), using the following formula:

[0027] T eta_new New estimated delivery time (in minutes) is used for partial display refresh; D remaining Remaining distance (unit: kilometers), obtained from the UAV flight control system; V: Drone flight speed (unit: km / min), obtained from real-time status information; ΔT wind Wind speed drag correction time (unit: minutes), calculated based on ambient wind speed (0.1 minutes in the example).

[0028] like Figures 1-2 As shown, in step S104, the loading or unloading status of the cargo is detected by the gravity sensor, and a status update signal is triggered when the cargo is removed.

[0029] Furthermore, in step S104, the gravity sensor continuously collects data on the status of the cargo, records weight change information during loading or unloading, and obtains preliminary status monitoring results. Based on the preliminary status monitoring results, the trend of weight change is analyzed. If the weight is detected to decrease to below the preset threshold, it is determined that the cargo has been unloaded, and a corresponding status change signal is generated. For the generated status change signals, the data transmission module sends the signal content to the central processing unit to confirm that the signal has been received and recorded; The system obtains confirmation information of signal reception from the central processing unit, records the specific time point of the state change through the internal clock system, and obtains a timestamp mark. Based on the timestamp markers and combined with historical data on cargo status, log entries for status changes are generated to ensure the completeness of log records. If data is missing or abnormal, the backup data verification mechanism is triggered by analyzing the integrity of the log records. Data from backup sensors is then compared to determine whether the final status change is accurate. After obtaining the final status change judgment result, the result is updated to the delivery management platform using a data synchronization mechanism to confirm that the status information in the delivery process has been synchronized.

[0030] Specifically, in step S104, during the delivery process, the system monitors the loading or unloading status of the goods in real time through gravity sensors and automatically triggers status update signals to achieve fully automated management of the entire process. The system has a built-in gravity sensor that collects cargo weight data 5 times per second. Assuming the initial loading weight is 2.8 kg, when the detected weight change exceeds the threshold of 0.2 kg, for example, when the current weight drops to 0.1 kg, the system automatically determines that the cargo has been unloaded. The system calculates the weight change rate using a built-in algorithm. The formula is: Change rate = (Initial weight - Current weight) / Initial weight. The change rate is 96.4%, which is higher than the preset unloading threshold of 90%, thus confirming that the unloading behavior is successful. The system generates a status update signal with a data packet size of 0.3KB, which is transmitted to the central processing unit through the internal communication module. The transmission delay is controlled within 0.1 seconds to ensure real-time performance. The central processing unit analyzes the signal integrity. If the verification result shows that the data integrity is 98.5%, which is higher than the minimum requirement of 95%, the signal is confirmed as valid. Otherwise, the system will automatically retransmit the signal to ensure reliability. To form a closed business loop, the system compares the unloading status information with the delivery task database to confirm the task completion rate. For example, if the current task progress is updated to 100%, a 0.2KB status log is generated and uploaded to the cloud for backup via a security protocol. If the network is unstable, it is cached to local storage and automatically synchronized after the connection is restored to ensure that the information is not lost. Through the above process, from weight detection to status update and information synchronization, a tight logical chain is formed to ensure accurate recording of delivery status.

[0031] In one embodiment, in step S104, the loading or unloading status of the goods is detected by a gravity sensor, and the system determines whether the goods have been unloaded based on the rate of change of weight, calculated using the following formula:

[0032] Where: R: weight change rate (dimensionless), representing the relative change in the weight of the goods; W initial Initial weight (unit: kilograms): The weight of the cargo when it is loaded. W current Current weight (unit: kilograms), the weight monitored in real time; Uninstallation determination: If R > R threshold (e.g. R) threshold If the value is 0.9, a status update signal is triggered, indicating that the goods have been unloaded.

[0033] like Figures 1-2As shown in Figure S105, the main control module controls the e-ink screen to update the delivery status and sends delivery completion information to the dispatch center via the wireless communication module.

[0034] Furthermore, in step S105, the latest delivery status data is obtained through the main control module, and the status information is classified to obtain the classified status identifier. Based on the categorized status indicators, the e-ink screen is driven to perform an update operation on the displayed content to determine that the e-ink screen has been refreshed to the corresponding status; When the e-ink screen refreshes to the corresponding state, the main control module generates a confirmation message for delivery completion, checks whether the message is complete, and if the message is complete, proceeds to the next transmission process. The generated confirmation information is packaged using a wireless communication module to obtain a data packet to be transmitted. The data packet to be transmitted is sent to the dispatch center through the wireless communication module, and a successful transmission feedback signal is obtained to confirm that the data has arrived. Based on the successful delivery feedback signal, record the time point of information interaction, and combine it with the historical delivery status to obtain a complete status change log; For the complete state change log, a data synchronization mechanism is used to upload it to the storage unit of the scheduling center. The upload is then checked to determine if it was successful. If successful, the entire process is complete.

[0035] Specifically, in step S105, after the delivery task is completed, the main control module controls the e-ink screen to update the delivery status through a series of automated processes, and sends the delivery completion information to the dispatch center through the wireless communication module, forming a complete business closed loop. After receiving the data signal that the delivery task is completed, the main control module automatically triggers the e-ink screen display update command. Assuming that the resolution of the e-ink screen is 800x600 pixels and the refresh rate is set to once per minute, the system switches the task status from in progress to delivered. The displayed content occupies 0.5KB of storage space to ensure low power consumption operation. The system's built-in algorithm optimizes the displayed content and calculates the proportion of the display area occupied by the formula: Occupancy ratio = Display content pixels / Total pixels. The result is 12.5%, which is lower than the preset display optimization threshold of 20%. Therefore, the system automatically adjusts the font size to 14 to improve visibility. The main control module generates a delivery completion feedback data packet, which is 0.8KB in size. It is transmitted to the dispatch center via a 4G network through the wireless communication module. The transmission rate is controlled at 2Mbps and the delay is no more than 0.2 seconds. If the signal strength is detected to be lower than -85dBm, the system automatically switches to the backup 3G network to ensure stable data transmission. After receiving the data, the dispatch center verifies it. If the data integrity analysis result is 97.3%, which is higher than the minimum standard of 96%, the feedback is confirmed to be valid, and the task status is marked as completed in the database. At the same time, a 0.4KB confirmation receipt is generated and returned to the main control module through an encrypted channel. If the verification fails, the retransmission mechanism is automatically triggered. To ensure business integrity, the system compares the completed information with the delivery logs and calculates the task completion time deviation using the formula: Deviation = Actual completion time - Expected completion time. Assuming the result is -3 minutes, which is less than the allowable deviation of 5 minutes, the task is considered to meet expectations. The log data is then compressed to 0.3KB and stored locally for backup, waiting to be automatically uploaded to the cloud during off-peak hours at night, forming a tight logical chain from status display to information feedback to data archiving.

[0036] In one embodiment, in step S105, the main control module controls the e-ink screen to update the delivery status and sends delivery completion information to the dispatch center via the wireless communication module. The system calculates the occupancy ratio of the displayed content to optimize visibility and ensure low-power operation. The calculation formula is as follows:

[0037] Where: O: Display occupancy ratio (dimensionless), representing the proportion of the displayed content to the total number of pixels on the screen; P content : The number of pixels to display content (unit: pixels), such as the pixels occupied by the delivery status text; P total Total number of pixels on the screen (unit: pixels), for example, e-ink screen resolution (800×600 pixels); Optimize decision: If O> Othreshold (O) threshold If the value is 0.2, adjust the font size or layout to reduce the percentage of space occupied.

[0038] like Figures 1-2 As shown in step S106, in the empty state, the main control module controls the e-ink screen to enter sleep mode, displaying static text and reducing power consumption.

[0039] Furthermore, in step S106, for the empty box state, the current equipment operation information is obtained through the main control module to determine whether the conditions for entering the sleep mode are met. If the conditions are met, a mode switching command is generated to confirm that the equipment state has been adjusted. According to the mode switching command, the e-ink screen is driven to perform the sleep mode operation, the displayed content is adjusted to fixed text, and a signal is received that the displayed content has been updated; In response to signals that the displayed content has been updated, the main control module monitors the power consumption data of the e-ink screen. If the power consumption data is higher than the preset threshold, the device parameters are adjusted to ensure that the power consumption has been reduced to the target range. Based on the information that the power consumption has been reduced to the target range, obtain the device control log, record the time points of state triggering and mode switching, and obtain a complete device state change record; For complete equipment status change records, a data synchronization mechanism is used to transmit them to the background storage unit, and it is determined whether the transmission is complete and whether the data has been saved. Based on the confirmed information that has been saved, the main control module generates a status monitoring report, which, combined with historical data on the empty container status, yields complete status information of the equipment operation.

[0040] Specifically, in step S106, in the empty box state, the main control module controls the e-ink screen to enter sleep mode through an automated process to reduce power consumption and display static text. The specific implementation method is as follows: the system first detects the empty box state through the built-in sensor and triggers the main control module to send a sleep command to the e-ink screen. Assuming the e-ink screen size is 400x300 pixels, the refresh rate is reduced to once per hour in sleep mode, and the static text content is "Empty box on standby", occupying only 0.2KB of storage space. The system calculates the current power consumption percentage using a power optimization algorithm. The formula is: Power consumption percentage = Current power consumption value / Maximum power consumption value. Assuming the current power consumption value is 0.1mW and the maximum power consumption value is 1.0mW, the calculation result is 10%, which is lower than the preset threshold of 15%. Therefore, the system confirms that the sleep mode is effective. The main control module analyzes the static text display effect and calculates the text coverage rate. The formula is: Coverage rate = text pixels / total pixels. Assuming that the text pixels are 6,000 and the total pixels are 120,000, the coverage rate is 5%, which meets the low visual interference standard and does not require adjustment of display parameters. The system generates a 0.1KB status report from the empty box status data and transmits it to the local monitoring terminal via a low-power Bluetooth module. The transmission rate is set to 0.5Mbps and the latency is controlled within 0.3 seconds. If the connection fails, it will automatically switch to the backup infrared transmission mode. To ensure a closed-loop business process, the system associates the empty enclosure status with the equipment maintenance log and calculates the empty enclosure duration using the formula: Duration = Current Time - Time Entering Empty Enclosure. Assuming the result is 2.5 hours, which is lower than the maintenance trigger threshold of 3 hours, it is determined that no maintenance intervention is required. The log is then compressed to 0.05KB and stored locally. When the equipment is connected to the network, it is automatically synchronized to the management platform, forming a complete logical chain from status detection to sleep control and data recording.

[0041] In one embodiment, in step S106, when the device is empty, the main control module controls the e-ink screen to enter sleep mode. The system calculates the power consumption percentage to confirm the effectiveness of the sleep mode and ensures that the power consumption is reduced to the target range. The calculation formula is as follows:

[0042] Where: R p Power consumption percentage (dimensionless), representing the ratio of current power consumption to maximum power consumption; P current Current power consumption (unit: milliwatts), actual power consumption in sleep mode; P max Maximum power consumption (unit: milliwatt), the maximum power consumption in normal display mode; Hibernation confirmation: If R p <R threshold (R) threshold If the value is 0.15, then the hibernation mode is effective; otherwise, adjust the parameters.
