Description

Technical Field

[0001] This invention relates to the field of logistics information technology, and in particular to a portable method, apparatus, device, and storage medium for printing waybills. Background Technology

[0002] In the current daily operations of the express delivery industry, when printing waybills, couriers typically need to manually access the printer connection interface, search for available nearby devices, and complete the connection configuration one by one before they can begin the printing process. This operation involves numerous and repetitive steps, which significantly increases unnecessary time consumption, especially in scenarios where couriers print frequently, thus affecting overall work efficiency.

[0003] It's worth noting that the printing equipment used by delivery drivers in their daily work is mostly fixed and specialized terminals. The printer models and users are relatively stable, and frequent changes to printing equipment are rare in actual operations. In this case, requiring delivery drivers to repeatedly perform manual search and connection operations every time they perform a printing task is not only redundant and cumbersome, but also a waste of working time and energy.

Detailed Implementation

[0033] This invention provides a portable waybill printing method, apparatus, device, and storage medium. The method is used to establish dynamic customer profiles and manage customers based on these dynamic customer profiles.

[0034] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" or "having" and any variations thereof are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 The first embodiment of a portable waybill printing method according to the present invention includes: S101. Initialize the feature database. The mobile terminal creates a feature database for storing multi-dimensional feature data of the printer and initializes the feature database. S102. When the automatic connection condition is triggered, the mobile terminal calls the priority sorting algorithm to score the priority of the printers in the database and determine the connection priority of the printer. S103. Based on the connection priority of the printers, determine the target printer from the printers and initiate automatic connection; S104. If automatic connection fails, enable manual connection mode. If manual connection fails, perform anomaly diagnosis and output the diagnosis results and solutions. S105. After completing the connection and interaction with the printer, update the multi-dimensional feature data of the corresponding device in the printer feature database.

[0036] This invention, through setting connection priorities, improves the success rate of automatic device connections, greatly simplifies connection operations, and lowers the technical threshold. The duration of each connection is reduced, saving couriers' daily connection time and significantly improving overall order processing efficiency. Furthermore, by predicting the connection success rate of high-priority devices, it effectively filters out devices with high historical scores but poor current status, thus focusing automatic connection on devices with good historical performance and good current status, greatly improving the efficiency and first-time success rate of automatic connections. This invention also reduces operational interruptions caused by connection problems, improving the overall operational efficiency of logistics, warehousing, and other industries, and has significant commercial value.

[0037] Please see Figure 2 In a second embodiment of the portable label printing method of the present invention, the initialization of the feature database involves the mobile terminal creating a feature database for storing multi-dimensional feature data of the printer and initializing the feature database, including: S201. When the mobile terminal starts the application, it automatically creates a feature database to store multi-dimensional feature data of the printer. In some embodiments, when an application on a mobile terminal is launched, the system automatically creates a feature database locally to store multidimensional feature data of the printer. As a preferred implementation, this database is implemented using the lightweight SQLite database to meet the mobile terminal's requirements for efficient read / write operations and low resource consumption.

[0038] S202, The mobile terminal initializes the feature database; In some embodiments, the mobile terminal initializes the feature database by defining and creating a data table structure for storing multidimensional features of each printer. The core fields of this data table are carefully designed to comprehensively characterize the printer's connectivity features, including: Unique Device Identifier: Preferably, the printer's Bluetooth MAC address is used as a globally unique identifier to ensure that different printer devices can be accurately distinguished and to avoid confusion with other Bluetooth devices.

[0039] Successful historical connection count: This field records the total number of times a Bluetooth connection has been successfully established with this printer. This data is a core indicator for evaluating device connection reliability.

[0040] Last Connection Time: This field records the timestamp of the last successful connection to this printer, accurate to the second. This data is used to determine the device's recent activity and usage frequency.

[0041] Average connection duration: This field is used to quantify the connection efficiency with the device by calculating the average of the time (in seconds) of all historical successful connection processes.

[0042] Historical connection failure rate: This field is calculated using the formula (number of failed connections / total number of connection attempts) × 100%, and is presented as a percentage to visually demonstrate the device's connection stability.

[0043] Historical Average Signal Strength: This field summarizes the average Bluetooth signal strength over historical connection periods. As a specific implementation, signal strength can be quantified as a value from 1 to 5, corresponding to 1 to 5 signal bars on the icon. This average reflects the basic signal conditions when connecting to the device.

[0044] S203. Encrypt the multidimensional feature data of the printer in the feature database.

[0045] This invention ensures that the feature data of each connection interaction can be reliably saved and will not be lost when the application is switched to the background or temporarily exited; it greatly improves the security of user privacy and business data and can prevent the leakage of sensitive information; the data involving label printing is encrypted, which can meet the compliance requirements of data security and privacy protection and enhance users' trust in the product.

[0046] Please see Figure 3 A third embodiment of a portable label printing method according to the present invention, wherein when an automatic connection condition is triggered, the mobile terminal calls a priority sorting algorithm to score the priority of printers in the database and determine the connection priority of the printer, including: S301. In response to the automatic connection condition being triggered, the mobile terminal calls the priority sorting algorithm to score the priority of the printers in the feature database. S302. Determine the connection priority of the printer based on the priority score.

[0047] The calculation formula for the priority sorting algorithm is as follows: ; Where A represents the number of successful historical connections, B represents the weight value of the most recent connection time, C represents the average connection duration, D represents the average historical signal strength, and E represents the historical connection failure rate; α, β, γ, δ, and ε are the weighting coefficients corresponding to A, B, C, D, and E, respectively. .

[0048] The priority scoring formula in this invention is a multi-factor weighted comprehensive evaluation model that can accurately identify devices with stable historical performance, recent activity, fast connection and good signal quality as priority connection targets. This fundamentally avoids the problem of selecting printing devices due to misleading single indicators, and greatly improves the success rate and quality of automatic connection.

[0049] Please see Figure 4 A fourth embodiment of a portable label printing method according to the present invention includes determining a target printer from the printers based on the printer's connection priority and initiating an automatic connection, comprising: S401. Based on the printer's connection priority, call the printer connection success rate prediction model and output the predicted success rate. S402. Compare the predicted success rate with the preset printer connection success threshold. S403. Determine printers whose predicted success rate is greater than or equal to the connection success threshold as target printers; S404: Initiate an automatic connection to the target printer.

[0050] In this embodiment of the invention, a connection success rate prediction model is invoked, and real-time variables such as the current signal strength, the success rate of the last three connections, and the number of Bluetooth devices in the environment are input for prediction. This mechanism can sensitively perceive the current state of the device and instantaneous changes in the environment.

[0051] In some embodiments, a printer with the highest historical score may be filtered out if the current signal is weak, as the model determines its predicted success rate to be low. This ensures that the system ultimately initiates a connection not only with the best historical score but also with the highest probability of a successful connection at present, fundamentally improving the success rate of automatic connections.

[0052] Please see Figure 5 The fifth embodiment of a portable label printing method in this invention includes the following steps: if automatic connection fails, a manual connection mode is activated; if manual connection fails, anomaly diagnosis is performed, and diagnostic results and solutions are output, including: S501. In response to automatic connection failure, enable manual connection mode; S502. In the manual connection mode, a printer list is generated and displayed, and the devices in the printer list are sorted according to a preset intelligent sorting algorithm. S503. In response to the connection failure after the user selects the target printer in the list, the intelligent anomaly diagnosis algorithm is invoked. S504. Based on the connection failure phenomenon, device characteristic data, and current environment data, locate the root cause of the failure and generate corresponding solution prompts.

[0053] The embodiments of this invention utilize multi-dimensional correlation analysis to achieve highly accurate and reliable diagnostic results. In some embodiments, it can clearly distinguish whether the timeout is due to weak signal, excessive interference, or the printer not being powered on, thereby transforming ambiguous fault phenomena into clear and locatable root causes, providing a scientific basis for subsequent solutions.

[0054] Please see Figure 6 The sixth embodiment of a portable label printing method according to the present invention includes updating the multi-dimensional feature data of the corresponding device in the printer feature database after completing the connection and interaction with the printer, including: S601. After completing the connection interaction with the target printer, obtain the interaction result of this connection, including connection success or connection failure. S602. In response to the interaction result, update the multi-dimensional feature data corresponding to the target printer stored in the printer feature database of the mobile terminal; The multidimensional feature data includes: the number of successful historical connections, the time of the most recent connection, the average connection duration, the historical connection failure rate, and the average historical signal strength.

[0055] When the interaction result is a connection failure, updating the multidimensional feature data includes: Update the total number of connection attempts and the historical number of failed attempts; Based on the updated number of failures and the total number of attempts, the historical connection failure rate is recalculated and updated; the reason for this connection failure is recorded in the database.

[0056] The embodiments of the present invention ensure that the result of each connection practice, whether successful or not, is fed back to the database in real time and accurately; and ensure that the system's connection strategy can adaptively adjust with changes in device status, always striving to select the most reliable device at the moment.

[0057] In some embodiments, multidimensional feature data such as the number of successful historical connections and average connection duration must be calculated based on complete historical records to be of reference value. This embodiment mandates updates after each interaction, ensuring that these statistical indicators can fully reflect all historical situations from the first connection to the present, avoiding decision-making biases caused by missing or lagging data, and providing a solid and reliable data foundation for all upstream algorithms.
