Description

Technical Field

[0001] The present invention relates to the technical field of intelligent pile diagnosis, and in particular to a maintenance data storage method and system based on a QR code. Background Art

[0002] With the rapid development of smart devices and IoT technology, the use of smart piles (such as power piles, charging piles, monitoring piles, etc.) has gradually become popular. These devices are usually equipped with sensors and wireless communication modules to collect, transmit and store dynamic data information of the devices. However, in actual applications, the operation and maintenance management of smart piles still faces many challenges.

[0003] Currently, the operation and maintenance of smart piles mostly rely on manual inspections and on-site maintenance. Workers need to go to the equipment site to manually collect data and diagnose faults. Since the equipment is usually scattered and restricted by the intranet environment, workers cannot access the dynamic data information of the equipment in real time and can only wait for regularly uploaded data to make fault judgments and handle them. In this process, problems such as response delays, untimely data, and difficulty in quickly troubleshooting often occur.

[0004] Although the existing equipment monitoring system can view the real-time status of smart piles on the background platform, it often requires a lot of manual intervention due to the lack of effective on-site fault diagnosis means and real-time control functions. Therefore, how to efficiently combine equipment data with maintenance processes, improve equipment fault handling efficiency, and ensure data security and authority management at the same time is an urgent problem to be solved in the operation and maintenance management of smart piles. Summary of the invention

[0005] In view of this, the present invention proposes a maintenance data storage method and system based on QR code, aiming to solve the problem that the current technology cannot perform effective on-site fault diagnosis means and real-time control functions.

[0006] The present invention proposes a maintenance data storage method based on a two-dimensional code, comprising: Obtaining basic information and dynamic data information of a smart pile, wherein the basic information of the smart pile includes unique identification information of the smart pile, encoding the basic information of the smart pile to obtain encoding information of the smart pile, and generating a two-dimensional code information of the smart pile according to the encoding information of the smart pile; The dynamic data information is uploaded to the data storage platform via wireless communication. The data storage platform generates a device status link according to the dynamic data information. There is a mapping relationship between the device status link and the QR code information of the smart pile. The dynamic data information is transmitted using an encryption algorithm; Adding an instruction set for docking with a device control interface to the QR code information of the smart pile, and associating the instruction set with the device status link; The mobile terminal can enter the device control interface and obtain dynamic data information by scanning the QR code information of the smart pile. The fault status of the smart pile can be checked through the dynamic data information. When the smart pile has a fault, the smart pile can be repaired. After the repair is completed, the collection frequency and upload frequency of the dynamic data information of the smart pile can be modified through the device control interface to confirm in real time whether the fault has been eliminated, and the maintenance data can be uploaded to the data storage platform for storage.

[0007] Furthermore, the specific content of obtaining the basic information and dynamic data information of the smart pile is: obtaining the basic information of the smart pile and obtaining the dynamic data information according to the built-in sensor of the smart pile; The unique identification information of the smart pile includes a unique identification device ID, a device model and device parameters; The dynamic data information includes the potential parameters of the smart pile, the collection frequency of the smart pile, the upload frequency of the smart pile, the fault status of the smart pile, and the historical maintenance records and fault records of the smart pile.

[0008] Furthermore, the basic information of the smart pile is encoded to obtain the encoding information of the smart pile, and the two-dimensional code information of the smart pile is generated according to the encoding information of the smart pile. The specific content is: the basic information of the smart pile is converted into a character string through the Base64 encoding method to obtain the encoding information of the smart pile, and then the encoding information of the smart pile is converted into a two-dimensional code pattern through the ZXing library.

[0009] Furthermore, the dynamic data information is uploaded to a data storage platform via wireless communication, the data storage platform generates a device status link based on the dynamic data information, the device status link is mapped to the QR code information of the smart pile, and an encryption algorithm is used for transmission during the dynamic data information transmission process. The specific content is: the dynamic data information is converted into a standardized format through Base64 encoding, and encrypted using a symmetric encryption algorithm to obtain the encrypted dynamic data information and generate an encryption key, the encrypted dynamic data information is uploaded to the data storage platform via wireless communication, the data storage platform extracts the encryption key and decrypts the encrypted dynamic data information to obtain the dynamic data information, and then associates the dynamic data information with the basic information of the smart pile to obtain the device status link.

[0010] Further, the instruction set for docking with the device control interface is added to the two-dimensional code information of the smart pile, and the instruction set is associated with the device status link. The specific content is: the instruction set is converted into a string through Base64 encoding and embedded into the two-dimensional code information of the smart pile, and the instruction set is associated with the device status link; The instruction set connected to the device control interface includes device status query instructions, device configuration instructions, and fault alarm instructions.

[0011] Furthermore, the mobile terminal also includes identity authentication, and different levels of identity authentication are performed according to the account level of the mobile terminal logged in, and different levels of authority correspond to different levels of identity authentication after entering the device control interface.

[0012] Furthermore, the account level includes a primary account level and a secondary account level, which correspond to the primary identity authentication and the secondary identity authentication in the identity authentication respectively; The different permission levels include primary permission and secondary permission, the primary identity authentication corresponds to the primary permission, and the secondary identity authentication corresponds to the secondary permission.

[0013] Furthermore, the first-level authority includes modifying the dynamic data information in the device control interface and handling the smart pile failure, and the second-level authority includes querying the dynamic data information and historical data in the device control interface.

[0014] Furthermore, the modification of the frequency of collecting and uploading dynamic data information of the smart pile through the device control interface also includes that the device control interface will conduct a second confirmation of the modification according to the power of the smart pile.

[0015] Compared with the prior art, the beneficial effect of the present invention is that: the maintenance data storage method based on QR code of the present invention collects the dynamic data information (such as potential parameters, fault status, etc.) of the equipment in real time through the built-in sensor of the smart pile, and encrypts these data and uploads them to the data storage platform through the wireless communication module. This not only ensures the real-time nature of the data, but also effectively solves the problem of data delay in the traditional method, and enhances the timeliness and accuracy of equipment status monitoring; the smart pile QR code contains the basic information of the equipment, dynamic data information and the instruction set for docking with the equipment control interface, and the operation and maintenance personnel can quickly obtain the equipment information and perform control operations by scanning the QR code. This integrated QR code technology simplifies the traditional equipment management process. On-site staff do not need to access a complex background platform or manual measurement, but can quickly locate faults and handle them with the help of a mobile terminal; based on the account level identity authentication mechanism, identity authentication is performed according to the authority level of different user accounts, and different operation permissions are granted. For example, the first-level account (administrator) has complete equipment management and control authority, and can perform equipment configuration and fault handling; while the second-level account (ordinary operation and maintenance personnel) can only query the equipment status and historical data, and cannot change the equipment configuration. In this way, the system can achieve fine-grained permission control, effectively avoiding misoperation and malicious control; when a device fails, the staff can quickly view the current fault status and historical maintenance records of the device by scanning the QR code. Maintenance personnel can quickly diagnose and repair equipment failures based on the dynamic data information, fault records and equipment control instructions provided by the interface. After the maintenance is completed, the acquisition frequency and upload frequency of the smart pile can be modified through the equipment control interface to confirm in real time whether the fault has been eliminated. This function reduces the equipment downtime and improves the reliability of the equipment; the instruction set embedded in the QR code supports multiple operations such as equipment status query, configuration adjustment, and fault alarm. The operation and maintenance personnel can directly enter the equipment control interface according to the scanned QR code to perform remote configuration and fault handling. Through this integrated method, the operation is more flexible and efficient, and manual on-site operation is no longer required, which improves the automation level of equipment management; when modifying key parameters such as the acquisition frequency and upload frequency of the equipment, the present invention performs secondary confirmation based on the battery power and equipment status of the smart pile through the equipment control interface. This measure effectively prevents misoperation caused by insufficient battery power or other reasons, and enhances the safety and stability of equipment operation.

[0016] On the other hand, the present invention also proposes a maintenance data storage system based on a QR code, the system comprising: Smart pile terminal, data storage platform and mobile terminal; The intelligent pile end comprises: A QR code generation module is configured to generate the QR code information of the smart pile according to the basic information of the smart pile, and add an instruction set for docking with the device control interface; A data collection module is configured to collect dynamic data information in the smart pile; The data encryption module is configured to encrypt the dynamic data information in the smart pile to obtain the encrypted dynamic data information of the smart pile; A data transmission module, configured to transmit the encrypted smart pile dynamic data information to the data storage platform; The data storage platform comprises: The data decryption module is configured to decrypt the encrypted dynamic data information of the smart pile, obtain the dynamic data information, and transmit it to the database module; A database module is configured to store dynamic data information; A data association module is configured to associate the dynamic data information with the QR code module to obtain a device status link; The mobile terminal comprises: an authentication module, configured to authenticate the account level; A scanning module is configured to scan the QR code information of the smart pile; The display module is configured to display the dynamic data information of the smart pile and the basic information of the smart pile.

[0017] It is understandable that the above-mentioned maintenance data storage system based on QR code has the same beneficial effects, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] See also Figure 1 As shown, an embodiment of the present invention provides a maintenance data storage method based on a QR code, comprising: S1: Obtain basic information and dynamic data information of the smart pile, the basic information of the smart pile includes unique identification information of the smart pile, encode the basic information of the smart pile to obtain encoding information of the smart pile, and generate QR code information of the smart pile according to the encoding information of the smart pile; S2: Upload the dynamic data information to the data storage platform through wireless communication. The data storage platform generates a device status link based on the dynamic data information. There is a mapping relationship between the device status link and the QR code information of the smart pile. The dynamic data information is transmitted using an encryption algorithm; S3: Add an instruction set for docking with the device control interface to the QR code information of the smart pile, and associate the instruction set with the device status link; S4: The mobile terminal can enter the device control interface and obtain dynamic data information by scanning the QR code information of the smart pile. The fault status of the smart pile can be checked through the dynamic data information. When the smart pile has a fault, the smart pile is repaired. After the repair is completed, the collection frequency and upload frequency of the dynamic data information of the smart pile can be modified through the device control interface to confirm in real time whether the fault has been eliminated, and the maintenance data is uploaded to the data storage platform for storage.

[0021] Furthermore, the specific contents of obtaining the basic information and dynamic data information of the smart pile include: obtaining the basic information of the smart pile and obtaining the dynamic data information according to the built-in sensor of the smart pile; The unique identification information of the smart pile includes the unique identification device ID, device model and device parameters; The dynamic data information includes the potential parameters of the smart pile, the collection frequency of the smart pile, the upload frequency of the smart pile, the fault status of the smart pile, and the historical maintenance records and fault records of the smart pile.

[0022] Specifically, each smart pile has a unique device ID, which is used to uniquely identify the device. The device ID is the basis for distinguishing and managing the device from other devices, ensuring that the basic information of each smart pile can be accurately recorded and queried in the platform. The device ID is not only the identifier of the device in the entire system, but also facilitates the remote monitoring platform to manage each device. The device model indicates the type, specification and application scenario of the smart pile. Usually, different models of smart piles will differ in hardware design, performance indicators, and functional modules. The device model can help operation and maintenance personnel quickly understand the specific configuration of the equipment and provide targeted maintenance solutions when problems arise. The device parameters cover the working environment conditions, design specifications, communication protocols and other technical parameters of the smart pile, which is the basis for ensuring that the equipment can operate stably in a specific environment. The device parameter record can help operation and maintenance personnel understand the performance range and operating conditions of the equipment, and provide a scientific and reasonable basis for operation and maintenance.

[0023] Potential parameters: Potential parameters are one of the important indicators to describe the working status of smart piles, usually including the voltage, current, power and cathode protection potential of the equipment. Through real-time monitoring of potential parameters, it is possible to find out whether the power transmission of the equipment is stable, whether there are abnormal currents, overloads or voltage fluctuations, which is crucial for the normal operation of the equipment.

[0024] Collection frequency: The collection frequency refers to the frequency setting of the device to collect data. The adjustment of the collection frequency can be optimized according to the usage requirements of the device to improve data collection efficiency or reduce energy consumption. A reasonable collection frequency helps the device reduce power consumption without affecting normal operation and ensures timely feedback of necessary data.

[0025] Upload frequency: Upload frequency refers to the frequency at which the smart pile uploads the collected dynamic data information to the platform. The setting of this frequency directly affects the response speed of the device real-time monitoring system. High-frequency uploads can ensure real-time synchronization of data and timely reflect the health status of the device; while low-frequency uploads help save network bandwidth and device battery resources. By adjusting the upload frequency, the system can balance energy consumption and performance while ensuring the transmission of critical data.

[0026] Fault status: Fault status records various abnormal conditions that occur during the operation of smart piles, usually including electrical faults, mechanical faults, sensor faults, etc. These fault status data are of great reference value for troubleshooting and maintenance decisions. By analyzing historical fault status, operation and maintenance personnel can identify potential failure modes of equipment and make early warnings.

[0027] Historical maintenance records and fault records: Historical maintenance records and fault records contain all maintenance and fault information of the equipment since it was put into use. These records help track the long-term operation of the equipment, identify frequently occurring fault types, and provide a reference for future maintenance. The accumulation of historical records also helps optimize the maintenance cycle of the equipment and reduce the equipment failure rate.

[0028] It should be noted that by acquiring and recording the basic information and dynamic data information of the smart pile, the system can accurately manage and monitor each device. The unique identification information of the device ensures the uniqueness and traceability of the device in the system, while the dynamic data information provides feedback on the real-time operating status of the device, ensuring that managers can understand the health status of the equipment in a timely manner. Based on the real-time data collection and upload of the built-in sensors of the smart pile, the system can automatically generate a device status link to provide real-time data support for subsequent fault diagnosis and maintenance. Through automated data upload and fault handling, equipment management becomes more intelligent, reducing human intervention and improving management efficiency.

[0029] Furthermore, the basic information of the smart pile is encoded to obtain the encoding information of the smart pile, and the QR code information of the smart pile is generated according to the encoding information of the smart pile. The specific content is: the basic information of the smart pile is converted into a character string through the Base64 encoding method to obtain the encoding information of the smart pile, and then the encoding information of the smart pile is converted into a QR code pattern through the ZXing library.

[0030] Specifically, Base64 encoding is an encoding method that converts binary data into printable characters. It is usually used to convert non-text data (such as pictures, audio, device data, etc.) into plain text format for easy transmission through text protocols (such as HTTP). By encoding the basic information of the smart pile in Base64, various device information (such as device ID, model, parameters, etc.) can be converted into a unified encoded string to ensure lossless transmission of information between different platforms and devices; first, the basic information of the smart pile is converted into a string through Base64 encoding. Base64 encoding can compress device information into text format to ensure the simplicity of information and efficient transmission.

[0031] Secondly, the ZXing library is used to generate a QR code pattern from the Base64-encoded string. The QR code has high data storage density and readability, and can store a large amount of device information in a limited pattern space.

[0032] Finally, the generated QR code can be directly attached to the smart pile, allowing operation and maintenance personnel to obtain detailed information about the device by scanning the device QR code.

[0033] It should be noted that converting the basic information of the smart pile into a QR code can significantly simplify the equipment management process. The operation and maintenance personnel only need to scan the QR code through the mobile terminal to quickly obtain the basic information, status parameters, etc. of the equipment. There is no need for cumbersome manual recording and query processes, which improves the efficiency and accuracy of equipment information acquisition. The equipment information is converted into a string through Base64 encoding, which further improves the efficiency of information transmission. The string format after Base64 encoding is convenient for efficient and secure transmission through network protocols (such as HTTP, MQTT, etc.). As a carrier of data, the QR code can conveniently display and transmit equipment information, realize the instant transmission and storage of equipment information, and the QR code of the smart pile embeds the unique identification information and other key parameters of the equipment. When the equipment fails, the operation and maintenance personnel can quickly locate the specific information and working status of the equipment by scanning the QR code. This makes troubleshooting and maintenance operations more efficient, and the operation and maintenance personnel can understand the equipment's fault history, maintenance records, current status and other information in the shortest time, and optimize the maintenance plan; the present invention integrates equipment information with the control instruction set through QR code technology, making the equipment operation and maintenance process more intelligent. Staff can scan the QR code to obtain information such as the equipment status, fault alarm, and historical records, and can directly control and maintain the equipment through the mobile terminal. This intelligent operation and maintenance method greatly improves the management efficiency and automation level of the equipment.

[0034] Furthermore, the dynamic data information is uploaded to the data storage platform via wireless communication. The data storage platform generates a device status link based on the dynamic data information. There is a mapping relationship between the device status link and the QR code information of the smart pile. The encryption algorithm is used for transmission during the dynamic data information transmission. The specific content is: the dynamic data information is converted into a standardized format through Base64 encoding, and encrypted using a symmetric encryption algorithm to obtain the encrypted dynamic data information and generate an encryption key. The encrypted dynamic data information is uploaded to the data storage platform via wireless communication. After the data storage platform extracts the encryption key, it decrypts the encrypted dynamic data information to obtain the dynamic data information, and then associates the dynamic data information with the basic information of the smart pile to obtain the device status link.

[0035] Specifically, dynamic data information usually includes real-time operation data of smart piles (such as voltage, current, temperature, cathode protection potential, fault status, etc.), which may be in binary format or other complex data structures. In order to facilitate transmission, storage and cross-platform data parsing, these dynamic data information are first converted into a standardized text format through Base64 encoding. Base64 encoding converts the original data into a printable character set to ensure that the data can be reliably transmitted in network protocols (such as HTTP, MQTT, etc.) and will not be affected by character encoding problems. In order to protect the sensitive information of the device and user privacy, and prevent the data from being maliciously intercepted and tampered during transmission, the dynamic data information must be encrypted. Here, a symmetric encryption algorithm (such as AES, DES, etc.) is used to encrypt the Base64-encoded dynamic data information. This embodiment adopts the AES algorithm, and the symmetric encryption algorithm encrypts and decrypts data with the same key to ensure that the information is fully protected during wireless transmission. Even if the encrypted data is intercepted, it cannot be directly understood, which increases the security of the data. In order to ensure the security of the encryption algorithm, a unique encryption key needs to be generated. The key is the core of data encryption and decryption, which ensures that the data can be encrypted and decrypted in a predetermined manner. The key generation should be highly random to ensure the unpredictability and uniqueness of the key. The key can be a pre-shared key between the mobile terminal and the data storage platform, or a temporary key generated based on factors such as device ID and timestamp. Key management and protection are key to ensuring system security. The encrypted dynamic data information is uploaded to the data storage platform through wireless communication (such as Wi-Fi, Zigbee, 5G, etc.). Wireless communication is efficient, flexible, and has a wide coverage, which is suitable for data collection and transmission of remote devices. When the encrypted data is uploaded through wireless communication, it can avoid security issues caused by communication interruption or interference, and ensure that the data can be transmitted to the platform reliably and in real time. When the data storage platform receives the encrypted dynamic data information, the platform needs to extract the encryption key and use the same key to decrypt it. The decrypted data will be restored to the original dynamic data information for further analysis and processing by the platform. The decryption operation is completed by the storage platform. The platform obtains the encryption key through a secure channel and decrypts it according to the symmetric encryption algorithm to ensure the accuracy and integrity of the data. After successfully decrypting and restoring the dynamic data information, the platform associates the dynamic data with the basic information of the smart pile (such as device ID, model, parameters, etc.) to generate a device status link. The device status link is a structured data that contains basic information and dynamic data information of the smart pile, which can provide complete information support for subsequent fault diagnosis, status monitoring, data query, etc.

[0036] It should be noted that the present invention first converts dynamic data into a standardized format through Base64 encoding, and then encrypts the data through a symmetric encryption algorithm to ensure the security of the data in wireless communication. After receiving the encrypted data, the data storage platform uses the same key to decrypt it, restore it to the original dynamic data information, and associate it with the basic information of the smart pile to generate a device status link. Through this complete security encryption and data processing process, the system can provide efficient, secure, and real-time equipment monitoring and management services to ensure the confidentiality, integrity, and reliability of the data.

[0037] Furthermore, an instruction set for docking with the device control interface is added to the QR code information of the smart pile, and the instruction set is associated with the device status link. Specifically, the instruction set is converted into a string through Base64 encoding and embedded into the QR code information of the smart pile, and the instruction set is associated with the device status link; The command set connected to the device control interface includes device status query commands, device configuration commands, and fault alarm commands.

[0038] Specifically, when generating a QR code, the instruction set is associated with the device status link to ensure that the device control instructions can be executed based on the current device status. The device status link contains the real-time status information of the smart pile (such as potential parameters, upload frequency, fault status, etc.), which is a comprehensive reflection of the actual working status of the device. When the user scans the QR code, the system not only displays the status information of the device, but also executes corresponding instructions according to the current status of the device, such as querying the status when the device is operating normally, and alarming or adjusting the configuration in the event of a fault. This association ensures that the instruction set can be executed in the appropriate context, avoiding unnecessary operations or wrong configurations; the device control interface is a bridge for the device to interact with the external system. It communicates with the device through a specific protocol, receives and executes control instructions. The instruction set includes device status query instructions, device configuration instructions, and fault alarm instructions, which correspond to different functional modules of the device control interface. For example, the device status query instruction can obtain the operating status of the smart pile, collect data, etc.; the device configuration instruction can modify the working parameters of the device, such as the collection frequency and upload frequency; the fault alarm instruction can be used to trigger an alarm when an abnormality occurs in the device, and notify the operation and maintenance personnel to handle it.

[0039] It should be noted that by associating the instruction set with the device status link, the execution of the instruction set will be more intelligent and contextualized, reducing the risk of misoperation and improving the accuracy and pertinence of the operation. For example, if the device is in a faulty state, the control interface after scanning the QR code can automatically provide troubleshooting instructions, and when the device is operating normally, it can provide status query or configuration instructions. In this way, the entire system can dynamically adjust the control instructions according to the actual situation of the device, improving the flexibility and responsiveness of device management; through the instruction set connected to the device control interface, the system can manage and control the device in an all-round way. The diversification of the instruction set allows users to flexibly choose different operation modes and respond immediately to different situations (such as equipment failure, operating status, and maintenance needs). The addition of fault alarm instructions can realize automatic monitoring and alarm of equipment, greatly improve the efficiency of operation and maintenance, and timely warn of equipment failures, thereby reducing equipment downtime and maintenance costs.

[0040] Furthermore, the mobile terminal also includes identity authentication, which performs different levels of identity authentication according to the account level of the mobile terminal, and corresponding different permission levels after entering the device control interface according to different levels of identity authentication.

[0041] Furthermore, the account level includes a primary account level and a secondary account level, which correspond to the primary identity authentication and the secondary identity authentication in the identity authentication respectively; Different permission levels include primary permission and secondary permission. Primary identity verification corresponds to primary permission, and secondary identity verification corresponds to secondary permission.

[0042] Furthermore, the first-level authority includes modifying the dynamic data information in the device control interface and handling smart pile failures, and the second-level authority includes querying the dynamic data information and historical data in the device control interface.

[0043] Specifically, identity authentication is a security mechanism that ensures that only authorized users can access the device control interface and perform corresponding operations. In the operation and management process of smart piles, operations such as device configuration, fault handling, and data query are involved. These operations are crucial to the normal operation of the equipment, so the identity of the operator needs to be verified to prevent unauthorized personnel from making modifications or troubleshooting. By managing the account level, the system can grant different permissions to users of different levels to ensure the security of the system and the accuracy of operations; through the division of account levels, the system can dynamically adjust the user's access rights according to the user's identity and responsibilities. This permission control mechanism can assign different permissions based on the user's role, work tasks or work experience. The division of the first-level account level and the second-level account level can be configured based on the user's job responsibilities, access requirements or operation permissions. The first-level account usually has higher permissions and can perform more complex operations, while the second-level account is limited to lower-permission operations such as query and viewing; identity authentication is to distinguish users of different levels to ensure that users can only access content within their authority. The first-level account is usually held by core personnel such as equipment management personnel, operation and maintenance engineers or administrators, and has full-authority operation functions and can perform all equipment control operations, including equipment configuration, fault repair, data modification, etc. Level 2 accounts are usually held by ordinary operation and maintenance personnel, inspection personnel, etc., with lower permissions. They can only query and view the status of the equipment, but cannot configure or modify it. The refinement of permission control is to ensure that different users can perform appropriate operations according to their roles and responsibilities during the equipment management and control process. Level 1 permissions usually include more complex and sensitive operations, such as equipment configuration modification, adjustment of collection frequency, and fault handling. These operations have a greater impact on the operating status of the equipment and require higher permissions and management experience. Level 2 permissions are mainly for equipment query operations, including dynamic data viewing and historical data analysis, which usually have little impact on the normal operation of the equipment. Level 1 permissions include modification and fault handling of dynamic data information in the equipment control interface, which is the most critical permission in the system. Users with level 1 permissions can modify parameters such as the collection frequency and upload frequency of smart piles and adjust the working status of the equipment. At the same time, users with level 1 permissions can also handle equipment failures, such as restarting the equipment, restoring factory settings, replacing parts, etc., which are operations that directly affect the normal operation of the equipment; Level 2 permissions mainly include operations such as querying dynamic data information and historical data in the equipment control interface, which are non-sensitive, read-only operations. Second-level users can view the potential parameters, acquisition frequency, fault history, maintenance records and other information of the smart pile, but cannot make any modification operations. Through this permission control, ordinary operation and maintenance personnel can timely understand the operating status of the equipment and conduct daily inspections and maintenance, but it will not directly affect the operation and configuration of the equipment.

[0044] Furthermore, modifying the frequency of collecting and uploading dynamic data information of the smart pile through the device control interface also includes that the device control interface will conduct a second confirmation of the modification based on the power level of the smart pile.

[0045] Specifically, during the operation of the smart pile, the frequency of collecting and uploading dynamic data information directly affects the battery consumption of the device. Generally, higher collection and upload frequencies will increase the battery consumption of the device, which may cause the device to be too low in power and unable to continue to work normally. Therefore, when modifying the collection and upload frequency, the power status of the device must be considered. By introducing a power monitoring and secondary confirmation mechanism, it is ensured that the device does not perform operations that may cause excessive power consumption when the power is insufficient, so as to avoid the device from being unable to perform effective monitoring and fault repair due to insufficient power. Through the secondary confirmation mechanism, the system can judge the health of the current power of the device and remind the user whether to continue to modify it, so as to avoid excessive consumption of the device battery caused by high-frequency data collection and upload operations, thereby ensuring that the device can still perform necessary data upload and monitoring tasks normally when the power is insufficient, and maintain the continuous working ability of the device. The power secondary confirmation mechanism can avoid the negligence of the operation and maintenance personnel when adjusting the frequency of the device, reduce the misoperation caused by insufficient power of the device, ensure that the balance of the device battery will not be destroyed when the frequency modification is performed, and enhance the operation and maintenance reliability of the device. The combination of power and operation frequency makes the smart pile system more intelligent, which can automatically evaluate the power status and make corresponding prompts and reminders according to the specific situation. Such an automated management mode not only reduces the burden of manual intervention, but also improves the self-protection capabilities of the equipment and avoids potential operational errors.
