Description

Technical Field

[0001] The present invention belongs to the technical field of equipment inspection, and in particular relates to a PDA mobile terminal inspection management system, method, storage medium and computer program product. Background Art

[0002] With the continuous advancement of industrial automation, the expansion of automated production lines, the growth of production equipment, and the continuous reduction of on-site management and operation personnel. These equipment need to be efficiently, accurately and timely maintained, inspected and managed in daily operations to ensure their stable operation and maximize their effectiveness.

[0003] The traditional inspection work mode mainly relies on paper forms and manual records. Inspectors need to carry a large number of paper inspection forms and check the equipment one by one according to the preset inspection routes and items. This method has many significant defects.

[0004] First, paper forms are prone to damage and loss, resulting in incomplete and unreliable inspection data. Moreover, after the data is recorded on paper, the subsequent sorting, statistics and analysis work is extremely cumbersome, consuming a lot of manpower and time, and prone to human errors and omissions. For example, the manual processing of massive amounts of equipment inspection data often lags behind actual production needs, and potential equipment failures cannot be discovered in time, which may cause equipment failure and downtime, seriously affecting production progress and efficiency, and causing huge economic losses.

[0005] Second, the traditional inspection method lacks an effective real-time data transmission and sharing mechanism. After the inspection personnel find equipment abnormalities on site, they usually need to return to the office or use other communication methods to feedback the information to the relevant departments or personnel. This process has obvious time delays, which is not conducive to taking timely response measures. For example: if the equipment is found to be leaking oil during the equipment inspection, the operator needs to record the inspection situation on a paper document, and cannot promptly notify the manager and the maintenance personnel to quickly respond to the maintenance, which increases the equipment downtime and affects production efficiency.

[0006] Third, with the continuous development of technology, the complexity of equipment is increasing. Traditional manual inspection data is difficult to conduct comprehensive data trend analysis, and there are deficiencies in fault prediction and prevention. Traditional inspection methods are difficult to meet the maintenance requirements of such high-precision equipment.

[0007] Although there are some digital inspection systems on the market in recent years, the existing solutions still have limitations. For example:

[0008] The inspection process and data association are out of touch with the GK (suggested) management standards, and personalized needs are difficult to meet, such as: the authenticity of inspection data, timely notification of abnormal inspection data, inspection data and the company's spare parts management system, production management system data connection, etc., which cannot meet the daily management needs of the enterprise. Summary of the invention

[0009] In order to make PDA inspection more portable and efficient and to improve data processing capabilities, so as to overcome the many deficiencies of existing inspection methods and equipment, the present invention proposes a PDA mobile terminal inspection management system, method, storage medium and computer program product.

[0010] A PDA mobile terminal inspection management system that realizes one of the purposes of the present invention comprises:

[0011] Equipment basic ledger management module: used to import equipment ledgers through the system front end;

[0015] Inspection record module: used to record the inspection results of all inspection benchmark items and TPM items after the PDA mobile end inspection is completed.

[0016] The TPM items are used to refer to items that require the equipment to be shut down before they can be inspected, and their inspection cycles are usually longer, such as 1 month, 3 months, half a year, etc.; the inspection benchmark items are used to refer to items that need to be inspected and confirmed on a daily basis, and their inspection cycles are usually shorter, such as daily tire pressure checks on cars.

[0017] Further, the TPM management module includes: a project adding unit, a project binding unit and an expired project management unit;

[0018] The item adding unit is used to add TPM items, including: TPM item name, operation instructions, maintenance cycle settings and maintenance standards; after the TPM item is added, the corresponding maintenance item is added, including: maintenance part, maintenance standard, maintenance content, and maintenance method;

[0019] The item binding unit is used to bind the maintenance item in the TPM item to the device after the TPM item is added and set the most recent maintenance time of the maintenance item; the same device can be bound to multiple TPM items;

[0020] The expired project management unit is used to display all expired TPM projects according to the last project expiration time in the project binding module and the maintenance cycle of the TPM project itself; it is also used to query TPM projects that will expire at a certain time in the future, such as projects that will expire in the next month, three months, six months, etc.

[0021] The technical effects of the above technical solution include: refining the functions of the TPM management module, including adding daily TPM items, binding equipment and items, managing expired items, etc. This helps to ensure that equipment is maintained in a timely and effective manner, and improves the standardization and traceability of equipment maintenance.

[0028] The technical effects of the above technical solution include: enhancing the code scanning function of the PDA mobile terminal inspection module, supporting multiple code scanning methods, and improving the flexibility and convenience of code scanning. At the same time, through server-side decryption and database retrieval, the accuracy and security of the scanned code information are ensured.

[0029] Furthermore, when the inspection result is numerical, it automatically determines whether the value exceeds the set range. If it exceeds the range, the inspection item is marked as an inspection item that has been inspected abnormally but not processed. At the same time, it automatically detects missed inspection equipment, calls the message push mechanism, and regularly pushes the missed inspection equipment and the inspection items that have been inspected abnormally but not processed to relevant personnel to remind them to deal with them in time.

[0030] The technical effects of the above technical solution include: introducing automatic judgment and message push mechanism, real-time monitoring and early warning of numerical inspection results, timely detection and handling of abnormal situations. At the same time, by detecting missed equipment and pushing unprocessed items, the integrity and timeliness of the inspection work are ensured.

[0062] 5. Task approval module is used to complete TPM project approval management. It currently supports three levels of approval (such as team leader, department head, and section chief) and supports rejection of re-reporting operations. With the approval module, managers can review the on-site operation status after the equipment TPM or inspection is completed. Managers can review the maintenance or inspection process description and operation pictures submitted on-site.

[0063] 6. Fault maintenance module, used to manage fault maintenance records, including:

[0064] The legacy problem unit is used to record the legacy problems of the equipment found during the production and maintenance process. It can realize automatic reminders for legacy tasks to avoid forgetting legacy problems and form a closed-loop management of the entire process.

[0065] Fault analysis unit, used to analyze the causes of daily equipment failures and equipment maintenance principle and structure analysis. Equipment failure analysis articles can be uploaded in various forms such as files, pictures, videos, etc., and support temporary storage and publishing;

It can share articles and materials with all employees and conduct online learning, thus improving the overall equipment maintenance capabilities;

[0067] The shutdown fault management unit is used to record the detailed content of the shutdown fault in the equipment fault (name of the shutdown equipment, shutdown time, fault location, fault cause, and treatment countermeasures) and the equipment shutdown processing process. The fault processing process includes: temporary countermeasures or temporary countermeasures and permanent countermeasures, forming a full closed-loop management of the fault processing process.

[0068] 7. Equipment inspection management module, used to inspect equipment, including:

[0069] The benchmark book and benchmark item adding unit is used to establish an inspection benchmark book at the initial stage of equipment inspection, and establish inspection benchmark items in the benchmark book, including: inspection location, inspection content, inspection method, inspection type, inspection benchmark, numerical judgment benchmark (greater than or equal to, less than or equal to), inspection importance, inspection cycle, responsible person (on-site, maintenance), benchmark item status (enabled, disabled); the inspection type includes judgment type and numerical type, and the numerical type requires filling in the standard numerical range of the inspection item.

[0070] A reference book management unit is used to push the reference book to the account corresponding to the superior management after the reference book is written, and to review and confirm the reference book. The superior management can view the corresponding inspection content of the reference and the confirmation and rejection operations;

[0071] Benchmark book binding unit: used to establish a binding relationship between the device and the inspection benchmark book. The device can be bound to multiple benchmark books, and certain inspection items in the benchmark book can be specified for binding. It supports one-click binding and unbinding.

[0072] Inspection record unit is used to check all inspection contents after the inspection is completed on the mobile PDA. It can be done on the PC. If any inspection abnormality occurs, it needs to be confirmed and processed online to form a closed-loop management.

[0073] 8. PDA mobile endpoint inspection module, including:

[0074] The login module is used to enter the inspection homepage after scanning the personal login code with a PDA. After scanning the equipment QR code, the equipment inspection items will automatically pop up. The operator will confirm the inspection items in turn. There are two ways to scan the QR code: 1. Scan with a PDA scanner, 2. Scan with a camera. The personal login code is encrypted using the AES algorithm, and the login is quick without entering the QR code information. The device information is encrypted using the AES algorithm to generate the QR code information, which is pasted onto the device. The device code can be scanned with a PDA to perform equipment inspection. Abnormal inspection results are directly pushed to relevant staff to quickly convey abnormal inspection information, and the inspection results can be queried online.

[0075] PDA is a portable electronic device with barcode and QR code scanning functions, RFID reader and POS machine. In order to use PDA for equipment inspection more efficiently, the inspection personnel information and equipment inspection information are obtained by scanning QR codes. The inspection personnel information is encrypted and generated by the AES algorithm based on the personnel ID plus the key. The equipment inspection information is encrypted and generated by the AES algorithm using the device ID information, device number information and the key. The generated encrypted character information is converted into QR code information as the QR code of the equipment information and the inspection personnel information. At the same time, the http request protocol is added to the inspection personnel information, so that after scanning the inspection personnel information on the PDA, the PDA will automatically communicate with the server, and the server will automatically decrypt the inspection personnel information. Only after the verification is qualified can the equipment inspection authority be obtained.

[0076] The page adaptation development is carried out on the PDA mobile terminal, supporting at least two scanning methods, including: 1. Using the built-in barcode scanner of the PDA device for scanning inspection; 2. Using the Zxing library to develop and call the built-in camera of the device for scanning inspection; adding the https certificate to solve the problem that the camera cannot be called, so that the Android or iPhone mobile phone camera can be used to scan the code, which greatly improves the system compatibility. Scan the code using any of the two scanning methods mentioned above through a PDA or a mobile phone to obtain the scanned code information, send the scanned code information to the server for decryption, and obtain the plain text information of the device. The system retrieves the inspection benchmark items of the device and the TPM items that are due for maintenance from the database based on the plain text information of the device (verification fields: department, system, work calendar, personnel authority, etc., inspection item expiration calculation formula = last inspection time + inspection cycle >= current time), and the verification field is used to verify the ownership relationship between personnel and equipment based on personnel attributes and equipment attributes. For example: people in team A can only inspect the equipment of team A, people in team B can only inspect the equipment of team B, and equipment of team A cannot be inspected by people in team B; the inspection items are sent to the mobile terminal, and the inspection personnel at the mobile terminal check each item for inspection; after automatic verification by this system, there will be no missed inspection or re-inspection. There are two types of inspection items, one is judgment type (for example: whether the equipment has water or oil leakage), and the other is numerical type (for example: hydraulic station pressure 0.4-0.6mpa). When there is an abnormality in the judgment type inspection item, the reason for the abnormality must be filled in, and the numerical inspection item needs to fill in the actual data. After the results of the numerical inspection items are submitted, the system will automatically determine whether the value exceeds the set range. If there is an inspection abnormality or the value exceeds the tolerance, the background system will call the message push mechanism to send the abnormal information to the work group to achieve rapid transmission of abnormal information. The system will automatically detect missed inspection equipment and items that have been inspected and unprocessed. It will regularly push information about missed inspection equipment and unprocessed abnormalities, so that on-site personnel can respond to and deal with existing problems in a timely manner. The closed-loop management of the entire process is more efficient and accurate, and informationization makes data more transparent, greatly improving production energy efficiency.

[0077] 9. System setting module, used to set up the system, including:

[0078] The system registration unit is used to authenticate user information, such as: the requirement is that the company's personnel can register and perform double authentication of the work number and user, and the registration can be completed after passing; the registration information is submitted to the backend server for data verification through the system front-end interface. After registration, there is no usage permission by default, and it can only be used after the administrator's authorization; fill in the registered work number and password on the login interface, and the login can be completed after passing the server verification, and then enter the system homepage.

[0079] System login unit, used for system usage authorization authentication. The functions available after login are based on the authorized permissions.

[0080] System permission management unit is used to manage the use permissions of the entire system. It can set the system use permissions for each person; and the permissions can be dynamically configured;

[0081] The system message push unit is used to automatically push equipment inspection benchmark items, TPM items, exceptions to legacy issues, missed inspections, and expected unprocessed messages. The message push module also supports Cron expressions, and you can customize the message push time and frequency.

[0082] System organization maintenance unit, used to perform autonomous maintenance on team classification; add team classification information;

[0083] The work calendar unit is used to set the attendance calendar of the on-site team. The system calculates the TPM items and inspection benchmark item lists that need to be maintained for the equipment based on the attendance calendar.

[0084] The overall structure of the system adopted in the present invention is a front-end and back-end separation architecture, which forms a standardized process from SQL Server database → server → PC → PDA mobile terminal. The front and back interaction processes use Jwttoken algorithm signature verification to ensure the legitimacy of the request. The PC terminal can operate the system function module, and the PDA mobile terminal is used for equipment inspection. It also supports camera scanning and barcode scanning gun scanning, and uses https to make requests. The entire system is developed according to the standardized process, and all data is stored in the database, which can efficiently complete data interaction.

[0085] The front-end is developed using the latest VUE technology framework to develop the entire system UI interface and multiple sub-module functions. The UI interface interacts with the server interface to complete data operations and interactions. All data provided to the back-end needs to be validated to ensure data accuracy and avoid abnormal null values ​​and other problems;

[0086] The server adopts Java Springboot technology framework for development and SQL server data storage, develops corresponding communication interfaces to enable it to complete the interaction, and stores the final data in SQL Server database. The database provides data reading, writing, statistics and calculation for the back-end service program. The back-end will also check and verify the received data to ensure data security and accuracy. At the same time, JWT algorithm is added for signature authentication. In addition, multi-threaded TaskScheduler task framework is used for message task reminders, so that each user unit can customize the message reminder time and frequency. The server supports file upload and download technology.

[0087] The PDA mobile terminal uses a quick login code to log in. Users do not need to use an account password to log in. After logging in, you can use a PDA barcode scanner to scan the code. It also supports scanning with a camera and supports offline decoding of QR codes. This solution is compatible with Android and iPhone phones for online use. The PDA mobile terminal also uses the VUE framework to develop a mobile interactive interface.

[0088] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
