[0054] The present application is further described in detail below with reference to the accompanying drawings.

[0055] In an embodiment, as shown in the figure, Figures 1-6 The present application discloses an intelligent digital display torque wrench control method, applied to an intelligent digital display torque wrench, which comprises the following steps:

[0056] S10, a management work order is created, and the work order content in the management work order at least includes a work order number, a torque standard value, a tolerance range, a torque detection field for recording an actual detection torque value, and a detection state field for recording a work execution state result; the management work order is a data unit for guiding and recording the whole process of torque work, and is a basic carrier for system control and execution, and the core content thereof has the characteristics of structuring and parameterization. The work order number is a unique identifier of each work order, is generally automatically generated by the system, ensures that the corresponding task object can be accurately distinguished and positioned in multiple work orders, and has non-repeatability and traceability. The torque standard value is a reference parameter for guiding the intelligent torque wrench to perform a torque operation, represents a target torque size required to be reached in the assembly process, and is usually in units of newton meters or pound feet, and is a direct basis for evaluating whether the work meets the standard. The tolerance range is used to define the allowable error interval, that is, the upper and lower limit range of the actual detection torque value when deviating from the standard value, and the range determines whether the tightening operation is qualified, and is a boundary condition for judging the work quality. The torque detection field is a record item set in the management work order, and is used to store the actual torque value collected by the intelligent torque wrench after each operation, so as to perform subsequent comparison, analysis and tracing. The detection state field is another field for indicating whether the current work meets the quality requirement, and the value thereof is generally set according to the comparison result of the actual torque value and the tolerance range, and includes qualified, unqualified, undetected and the like, and is a core basis for judging whether the task is completed in the control process. The establishment of the whole field system makes the work process have the characteristics of configurability, judgeability and traceability, and supports closed-loop processing and automatic execution of data.

[0057] S20, according to the management work order, a two-dimensional code label for being attached to a product to be operated is generated, and when the intelligent digital display torque wrench scans the two-dimensional code label, the corresponding work order content is obtained; the above content is structured and packaged into two-dimensional code data according to a preset coding rule, is sent to a two-dimensional code generation terminal through an encryption channel, and is printed into a physical label, and then the label is attached to the corresponding product to be operated; as Figure 2As shown, when the code scanning module 1 in the intelligent digital display torque wrench scans the two-dimensional code label, the bound work order content can be parsed in real time and automatically loaded into the device, so that the standardized and task-based operation parameters can be obtained before each torque operation, the human input error is avoided, the rapid configuration of torque setting and the automatic docking of operation process are realized, and the accuracy and efficiency of production operation are improved.

[0058] S30, real-time receiving operation record parameters sent by the intelligent digital display torque wrench, wherein the operation record parameters are various parameters automatically recorded by the intelligent digital display torque wrench in the process of performing corresponding code scanning operation and torque operation based on the work order content; the operation record parameters refer to a set of data closely related to operation behavior automatically collected and generated by the intelligent digital display torque wrench during the operation process, which usually includes but is not limited to two-dimensional code scanning time, scanning position coordinates, actual torque value, operation response timestamp, operator identity and completion status of each operation action, etc., for reflecting the actual situation of each operation step during the execution process; the code scanning operation is an information reading behavior of the product to be operated by the built-in two-dimensional code recognition module during the execution process, for loading the work order parameters corresponding to the product, ensuring the correctness and consistency of the operation; the torque operation refers to the process of tightening operation according to the target torque parameter loaded, and the intelligent digital display torque wrench performs actual force action and real-time monitoring of torque application during the process, for judging whether the operation meets the work order setting requirements.

[0059] S40, updating operation of the work order content according to the operation record parameters, the updating operation at least including torque detection field updating operation for updating actual detection torque value corresponding to the torque detection field, and state updating operation for updating operation execution state result corresponding to the detection state field; by receiving the operation record parameters uploaded by the intelligent digital display torque wrench in real time, the updating logic of the work order content is automatically triggered, the actual detected torque value is first written into the corresponding torque detection field, and the quantitative record of the actual operation result is completed; then, the system compares the detection value with the standard torque value and the tolerance range preset in the work order, automatically judges whether the current operation meets the standard requirements, and writes the judgment result into the detection state field. The control logic realizes real-time archiving and state determination of each torque operation data, ensures that the work order content and the on-site operation are updated synchronously, improves the automation degree of data recording and the accuracy of operation state determination, and provides reliable support for subsequent quality traceability and process control;

[0060] Specifically, as Figure 2As shown, the intelligent digital display torque wrench is running in the work order mode, the system first scans the product two-dimensional code, automatically parses and loads the work order parameters associated with the product, including the target torque value and the allowable error range, saves the manual setting step, ensures the standardization and accuracy of the operation parameters. After loading, the wrench will collect the current applied torque value in the actual operation process, and compare it with the target value set in the work order, calculate the deviation percentage between the two, and the deviation result will be displayed on the display module 2 of the intelligent digital display torque wrench, so that the operator can monitor the operation state in real time. At the same time, the system has a hierarchical sound and light alarm mechanism, which automatically triggers different levels of prompts when the current torque value approaches or exceeds the threshold. For example, when the current value reaches 90% of the target value, the system starts a first level warning, prompting the operator that the upper limit of tightening is approaching through low frequency buzzing; When it reaches 100%, the system enters the second warning state, and at the same time, high frequency buzzing and yellow light are turned on to remind that the critical value is about to be reached; If it continues to exceed 105%, the system judges that the torque is out of tolerance, and immediately triggers a third level alarm, the red light is always on and accompanied by an emergency stop prompt, so as to effectively prevent the damage of threads or connection failure caused by over tightening. This process not only realizes the automatic guidance and dynamic warning of torque control, but also strengthens the over-limit protection capability, and improves the safety, accuracy and controllability of the whole operation process;

[0061] After step S40 is completed, i.e. after the operation record parameters are completed according to the operation record parameters, the system enters the data tracing and storage stage, at this time, all operation record parameters generated in this operation process are archived and the synchronization mechanism is triggered. Each operation record parameter corresponds to the currently bound management work order, and is associated with the update field in the management work order, including work order number, operation timestamp, actual torque peak value and operator identity. Among them, the work order number is used to identify the management work order corresponding to the current record, the operation timestamp accurately identifies the operation time in UTC format, the actual torque peak value is automatically collected by the intelligent digital display torque wrench when performing the corresponding torque operation, and is used to further compare the torque standard value and the tolerance range, and as the core basis for updating the torque detection field and the detection state field. The operator identity is derived from the operator ID information automatically recognized by the device during the operation process, which is synchronized with the previous scan record or manual mode operation, and is used for subsequent permission confirmation and responsibility tracing.

[0062] After the operation record parameters are generated, the system preferentially uploads them to the cloud database through wireless communication, and the work order management system stores them centrally, which is used to support subsequent task queue backtracking, job process visualization, report statistics and quality audit. If network connection anomalies are detected during the operation process, the system will automatically switch to a local data buffering mode and write the operation record parameters into a flash module configured locally in the intelligent digital display torque wrench. The module supports buffering up to 5000 job data, each of which contains complete management work order information, task queue execution order and the matching identifier of each target object, so that even in the absence of network or network fluctuations, all key data can be recorded completely and sequentially, without affecting the update and subsequent tracing of work order content. When the network is restored, the system automatically triggers the differential synchronization logic to retrieve the record data that has not been uploaded in the local flash, compares and removes it based on the timestamp and work order number, and sequentially supplements it to the cloud database according to the generation order, finally realizing the consistency synchronization of work order information and operation record parameters between the local and the cloud, and building a safe, stable, traceable and anti-interference whole-process data tracing mechanism.

[0063] In an embodiment, in the step S10, i.e. the step of creating a management work order, the following steps are included:

[0064] S101, acquiring current timestamp information and identification information of the work order creation terminal, and generating a corresponding work order number based on the timestamp information and the identification information;

[0065] S102, receiving input parameters input by the user into the work order creation terminal in real time, the input parameters at least including a product model, a torque standard value and a tolerance range;

[0066] S103, retrieving a set of preset work order configuration parameters corresponding to the product model, and filling the set of work order configuration parameters according to the association relationship established by the work order number and the input parameters to generate a corresponding management work order, wherein the set of preset work order configuration parameters includes a torque detection field and a detection state field.

[0067] In the embodiment, the timestamp information refers to high-precision time data generated by the system at the current moment of creating the work order, usually including year, month, day, hour, minute and second, and even can be accurate to millisecond level, for ensuring that each work order has time uniqueness basis; the identification information of the work order creation terminal refers to a unique number or identification code corresponding to the terminal device for initiating the work order creation operation, which can be generated according to the device serial number, network address or preset identity configuration, for identifying the creation source of the work order; the work order creation terminal refers to a software and hardware carrier with the ability to create, input and submit work orders, which can be an operation panel with touch input function, or an upper computer software system deployed in the terminal device; the input parameter refers to the structured parameter data actively input by the user when creating the work order, for describing the basic work demand of the current product, wherein the product model is a specific model identification of the operated target, for matching the corresponding process requirements in the database, the standard torque value is a standard reference value for guiding the tightening force setting in the work process, usually in N·m, and the tolerance range is a permitted fluctuation interval set around the standard torque value, for judging whether the work result is qualified; the preset work order configuration parameter set is a set of parameter templates defined in advance by the system for different product models, including process control fields related to the product model, for quickly filling the work order content.

[0068] Specifically, after the work order is created, the system automatically generates a unique work order ID, for example, 2105856510855, which is generated based on the current timestamp information and the identification information of the work order creation terminal, to ensure uniqueness in the entire production process; then, the system structurally associates the work order ID with the product model (for example, ABCD), the standard torque value (for example, 20.0 N·m) and the tolerance range (for example, ±2%) and other key parameters input by the user, and transmits the structured parameter data to the two-dimensional code generation terminal through an encrypted communication channel, and completes the two-dimensional code encoding and label output operation in the two-dimensional code generation terminal; wherein the two-dimensional code encoding content includes 12-digit encoding of the work order ID, 4-letter code of the product model, standard torque value with 0.1 N·m precision, and error value field representing tolerance range.

[0069] In an embodiment, in step S20, i.e. according to the management work order, generating a two-dimensional code label for pasting on the product to be operated, includes:

[0070] S201, structurally encoding the work order number and the input parameter based on the determined preset encoding rule, to generate corresponding two-dimensional code data content;

[0071] S202, transmitting the two-dimensional code data content to the two-dimensional code generation terminal through an encrypted communication channel, and generating a corresponding two-dimensional code label in the two-dimensional code generation terminal.

[0072] In this embodiment, after the system completes the creation of the management work order, it enters the two-dimensional code label generation phase, at which time the system will call the built-in encoding module to perform structured processing on the core information in the work order according to the pre-set encoding rules, including: work order number, product model, standard torque value, tolerance range and other key parameters. The encoding rule will assign a fixed encoding length and field identification bit to each type of field, so that the final generated encoding content has uniformity and parsability in format, for example, the work order number is placed as a 12-digit field at the beginning of the encoding, followed by the 4-letter code corresponding to the product model, and then the torque value field and error percentage field are arranged in turn in the form of floating-point numbers, forming a clear data carrier. After encoding is completed, the system sends the generated two-dimensional code raw data content to the connected two-dimensional code generation terminal through the established secure encryption channel. The terminal is deployed in the production line label printing module. After receiving the encrypted data, it first performs parsing and verification to confirm that the data structure is complete and has not been tampered with, and then triggers the local two-dimensional code rendering and printing logic, finally outputs a two-dimensional code graphic label with unique identification function, which is attached to the specified area of the product to be operated, for subsequent smart digital display torque wrench to scan and identify and load work order parameters.

[0073] In an embodiment, after step S20, i.e., after the step of generating a two-dimensional code label for attaching to the product to be operated according to the management work order, it further comprises:

[0074] S21, asynchronously receive the manual mode request sent by the smart digital display torque wrench, the manual mode request at least including the operator ID; the manual mode request refers to a work mode switching instruction initiated by the operator under special operation requirements, which is used to request to temporarily cancel the restriction of loading work order parameters by scanning code, and instead manually input or modify torque value, tolerance range and other key control parameters by the operator. The request needs to carry the unique identity of the operator when initiated; the operator ID is a number or certificate used to identify the identity of the current requester, usually corresponding to the enterprise personnel management system, which can take the form of employee number, card number, fingerprint code or device login certificate, etc., used to confirm whether the current operator has authorized qualifications.

[0075] S22. Call the local authorization ID database to determine whether matching data corresponding to the operator ID is found in the local authorization ID database. If no matching data is found, the manual mode request is rejected. The local authorization ID database is a data set deployed locally on the system, which records the identity information and permission levels of all operators with modification permissions. Upon receiving a manual mode request, the system calls this database for comparison to confirm whether a matching legitimate authorization record exists. Matching data refers to the complete permission information record corresponding to the operator ID retrieved from the authorization ID database, typically including the operator's identity, role, permitted operation parameters, and operation restrictions.

[0076] S23. Based on the matching data, the corresponding recording range is determined, and the corresponding confirmation instruction is generated based on the recording range. When the confirmation instruction is sent to the intelligent digital torque wrench, the corresponding manual operation parameters are automatically recorded. The manual operation parameters include at least the operator ID, the reason for the parameter modification, and the manual operation timestamp. The recording range refers to the parameter modification authority boundary determined based on the matching data, such as whether the operator can modify the standard torque value, the error range, or whether a specific work order field can be repeatedly modified, etc., which serves as an important constraint condition for the subsequent system to generate confirmation instructions. The confirmation instruction is a logical response instruction generated by the system after completing the authorization verification and authority boundary judgment. It is used to notify the wrench whether the current manual mode operation is allowed to be executed and to start the recording mechanism for the operation process. The manual operation parameters refer to the operation data content automatically recorded by the wrench during the user input or modification of key parameters after the manual mode is allowed, including the operator's identity, the reason for each parameter change, and the timestamp information of the completed operation, which is used for subsequent auditing and responsibility confirmation.

[0077] Specifically, in a body assembly production line, when the torque value needs to be temporarily adjusted due to special working conditions, the operator wrench sends a manual mode request. The system receives the request and identifies its operator ID as EMP119. It then calls the local authorized ID database for matching and finds that EMP119 is a technician with the authority to modify the torque value. The record range is limited to adjustment authority between 20N·m and 60N·m. The system generates a confirmation instruction allowing execution and transmits it back to the wrench. After the wrench enters manual mode, it is allowed to modify the parameters and automatically records a complete manual operation log with the operator ID as EMP119, the reason for modification as "change of assembly part model", and the time as May 7, 2025 14:32:10.

[0078] In one embodiment, if Figures 5-6 As shown, in step S40, i.e., the step of updating the job execution status result corresponding to the detection status field, the following steps are included:

[0079] S401, calculate a detection difference value between the actual detection torque value and the torque standard value;

[0080] S402, update the job execution state result corresponding to the detection state field according to the comparison result of the detection difference value and the tolerance range.

[0081] In this embodiment, the detection difference value refers to the result obtained by subtracting the actual detection torque value from the preset torque standard value during the execution of the torque operation, which is used to quantify the deviation between the current operation result and the target requirement. The difference value can be positive or negative, with a positive value indicating that the torque is over-standard and a negative value indicating that the torque is insufficient. The torque standard value is a target torque control parameter set in the management work order in advance, representing the ideal torque reference value that should be achieved during operation, usually in units of N·m, serving as a reference basis for determining whether the operation meets the standard. The tolerance range is the floating interval allowed by the system for the actual detection torque value to deviate from the torque standard value, with the upper and lower limits being symmetrically or asymmetrically set, for example, set to ±5% or +5% / -3%, serving as a boundary condition for determining whether the current difference value is within the allowed range. The detection state field is a structured data item in the work order for recording the current operation result determination state. After the system completes the comparison of the detection difference value and the tolerance range, the content of the field is automatically updated according to the result to identify whether the result of this torque operation is qualified, with common states including qualified, over-standard, and undetected. The job execution state result is the final determination result of the system after completing the current task operation, used to express the level state of the operation quality. This result is not only recorded in the detection state field, but can also be used as a key evaluation basis for subsequent quality control, report analysis, or responsibility tracing.

[0082] For example, in a motor shell assembly station, the torque standard value of a certain operation task is set to 30.0 N·m, the tolerance range is ±6%, and the actual torque value detected in a certain operation is 31.8 N·m. The system calculates the detection difference value as +1.8 N·m, and the corresponding deviation percentage is 6.0%, which is equal to the maximum tolerance value. At this time, the system determines the operation result as a qualified boundary value state, and automatically writes qualified into the detection state field of the work order corresponding to the task.

[0083] In an embodiment, in step S30, i.e., the step of receiving the operation record parameters sent by the intelligent digital display torque wrench in real time, the operation record parameters include scan code response timestamp record parameters, scan code response position parameters, torque adjustment response timestamp record parameters, and torque adjustment record parameters. The step further includes:

[0084] S301, if multiple consecutive scan code response timestamp record parameters are received in real time, the target object corresponding to the scan code response timestamp record parameters is retrieved in the management work order;

[0085] S302, sequentially add each target object to the newly created task queue, and receive the scan code response position parameter at the same time as the scan code response timestamp record parameter as the matching identifier of the corresponding target object;

[0086] S303, if the torque adjustment response timestamp record parameter is received, the current position parameter of the intelligent digital display torque wrench is acquired in real time;

[0087] S304, according to the current position parameter, the corresponding matching identifier is determined, and the torque adjustment record parameter is associated with the matching identifier corresponding to the target object, so as to execute the update operation of the corresponding target object on the work order content.

[0088] In this embodiment, the scan code response timestamp record parameter refers to the time information generated by the system to mark the scan code time after the intelligent digital display torque wrench successfully identifies the two-dimensional code label each time, which is usually recorded in high precision format for accurately identifying the occurrence sequence and corresponding time of each scan code action. The scan code response position parameter refers to the space position data of the wrench recorded by the system synchronously when each scan code action occurs, which can be derived from the positioning base station, work station number identification signal or built-in inertial positioning device arranged in the workshop, and the purpose is to bind the scan code event corresponding to a two-dimensional code with the actual work position, so as to realize accurate correspondence in the presence of multiple products to be worked on. The torque adjustment response timestamp record parameter refers to the information recorded by the system at the time when the torque action is completed, which is used for subsequent matching with the scan code sequence to ensure the effective association between the tightening operation and the scan code task. The torque adjustment record parameter refers to the work data automatically collected by the system after each torque tightening operation, including the actual detected torque value, tightening duration, peak fluctuation characteristics, etc., which is an important basis for work quality evaluation and work order field update. The target object refers to the specific data structure entity bound in the system with a product, component or task item represented by a certain scan code event and corresponding two-dimensional code, representing the object unit acted on by this operation behavior. The task queue refers to a group of to-be-executed operation lists constructed by the system according to the scan code sequence, each of which corresponds to a target object and its to-be-executed work content, and the task queue supports arrangement according to the scan code time sequence and can be used for sequentially scheduling the execution of work tasks. The matching identifier is a logical marker generated by the system for the target object, which is used to one-to-one bind the subsequent tightening operation with the corresponding scan code event, and its generation logic can be determined based on the scan code position parameter, timestamp, work station number or equipment number, etc.

[0089] For example, on an automobile chassis assembly line, an operator scans the two-dimensional codes of the front left, front right, rear left and rear right tires in turn, the system records four sets of scan code response timestamps, and identifies the corresponding four tire mounting positions through the workstation positioning system, generates four matching identifiers and sequentially adds them to the task queue. Subsequently, the operator uses the same wrench to tighten the four tires in turn, and the system collects the current actual torque value and operation time after each tightening is completed, and identifies which target object in the previous scan code record it matches according to the current position of the wrench, and then binds the current tightening data to the corresponding work order task, realizing data closed-loop pairing between continuous scanning and continuous operation.

[0090] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
