Description

Technical Field

[0001] This invention belongs to the field of archives management technology, and in particular relates to an information management system for thermal power plant archives with high availability. Background Technology

[0002] With the advancement of modern technology, archival construction has gradually shifted from paper-based to electronic, and archival management has fully entered the information age. Similarly, the construction of digital archives for coal-fired power plants is also progressing steadily, with a significant increase in the rate of electronic archives. Documentary archives, scientific and technological archives, accounting archives, physical archives, audio-visual archives, and other special archives have basically achieved full-text digitization. Archival management has evolved from simply receiving, managing, and storing to a one-stop service encompassing receiving, managing, storing, and using. Improving the archival management system to achieve document integration and the integration and sharing of archival information resources has become the dominant direction of current archival digitization construction.

[0003] Thermal power plant archives work adapts to the trend of the information age, transforming various archives generated during production and operation into digital archives information. By leveraging an information platform to form an archives information database, it achieves the sharing and management of all information resources, improves the efficiency of archives management, reduces business operating costs, enhances the level of intelligent management services for enterprises, improves the quality and efficiency of enterprise work, provides enterprises with comprehensive and multi-level archives informatization and decision support, and provides strong support for the sustainable and healthy development of enterprises.

[0004] Current archival systems typically focus only on the collection, management, and storage of archival information, resulting in numerous inconveniences in the use of this information. For example, users can only access archives through searches or catalog lookups, often encountering useless information. There are no other more convenient methods, and the accuracy of searches is questionable. Furthermore, user training is often neglected. Users typically have high demands for archival information, but current training materials are usually fixed and fail to connect with real-world applications. This disconnect between training and reality often leads to limited training effectiveness. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems by providing a highly available information management system for thermal power plant archives. This system utilizes QR code scanning technology, replacing the scanning object with KKS codes, to achieve rapid association between on-site equipment and archive information. Each device has a code, which can be associated with a file; scanning the code allows access to the file content. Using KKS codes avoids the problems of frequent use and difficulty in distinguishing on-site QR codes, as well as maintenance issues caused by QR code damage, addition, or replacement.

[0006] To achieve the above objectives, the present invention adopts the following technical solutions:

[0007] A highly available thermal power plant archive information management system includes a system server and an APP installed on a mobile terminal. The system server is connected to a database for storing thermal power plant archives. The thermal power plant archives include equipment archive information. The archive information of each equipment is associated with the corresponding KKS code in the database. When a user scans the KKS code of a field equipment using the APP, the APP uploads the scanned KKS code to the system server. The system server retrieves the corresponding equipment archive information from the database based on the received KKS code and sends it to the APP.

[0008] In the aforementioned high-availability thermal power plant archive information management system, this system interfaces with the ERP system and synchronizes the equipment KKS codes from the ERP system.

[0009] In the aforementioned thermal power plant archive information management system with high availability of archives, each APP user has a corresponding account authenticated by the identity authentication platform. The system server records the account ID and job responsibilities of each APP user, and provides archive access permissions for relevant devices to the corresponding account IDs according to their job responsibilities.

[0010] When the system server receives the KKS code uploaded by the APP user, it identifies the account ID of the APP user and determines whether the current APP user has access rights to the device corresponding to the current KKS code. If so, the device file information is sent to the APP user; otherwise, the sending is rejected.

[0011] In the aforementioned high-availability thermal power plant archive information management system, this system interfaces with the training system. This system provides a training interface for training system users to request equipment training, including the following steps:

[0012] A1. Obtain the training users who participated in the training in the training system;

[0013] A2. Obtain the training content for each training user;

[0014] A3. Match each training user to their account ID in this system;

[0015] A4. Determine the on-site equipment corresponding to each training content;

[0016] A5. Determine whether the APP user with the account ID mentioned in A3 has permission to access the field device mentioned in A4;

[0017] If not, then grant the on-site equipment permission to access the training file information of the account ID, and then execute A6; otherwise, execute A6 directly.

[0018] A6. Record the relationship between the relevant training users and the on-site equipment;

[0019] A7. When a training user requests equipment training in the training system, send them the corresponding file information of the field equipment associated with them;

[0020] When the APP user with the account ID mentioned in A3 scans the KKS code of the field device mentioned in A4, the corresponding file information of the field device is sent to the APP user.

[0021] In the aforementioned high-availability thermal power plant archive information management system, this system also interfaces with the ERP system and is used to execute the following steps:

[0022] B1. Identify equipment status based on the ERP system;

[0023] B2. When equipment is identified as being under maintenance, query the training users associated with it;

[0024] B3. Send the equipment maintenance file information to the training system as described in B2 for the training users to borrow or browse online.

[0025] In the aforementioned thermal power plant archive information management system with high availability of archives, the APP provides a borrowing portal, and the mobile terminal provides APP storage space. This APP storage space is controlled by the APP and is used to store the archive information downloaded after the user requests to borrow it. When the user requests to return the archive, the corresponding archive information in the APP storage space is deleted. When the APP is uninstalled, the corresponding APP storage space is released.

[0026] In the aforementioned thermal power plant archive information management system with high availability, the system encrypts the archive information borrowed by the APP by associating it with the corresponding account ID and the APP, and then sends it to the corresponding mobile terminal for download, so that the archive information in the APP's storage space can only be opened by the APP and the corresponding account ID.

[0027] In the aforementioned high-availability thermal power plant archive information management system, this system also includes a safety helmet equipped with sensors. The sensors detect the location of the safety helmet and execute the following steps:

[0028] C1. Extract, process, and package the file information of field equipment within the range of the location to make it ready for transmission;

[0029] When the C2.APP user scans the KKS code of the field device described in C1, the corresponding file information to be sent is sent to the APP user; the scope refers to the positioning location, that is, an area centered on the positioning location that extends outward from the positioning location by several diameters.

[0030] C3. When it is detected that the field equipment with the file information in the pending sending state has left the area covered by the safety helmet positioning position, the pending sending state of the relevant file information shall be released.

[0031] In the aforementioned thermal power plant archive information management system with high availability, step C1 is preceded by: the system server binding each safety helmet to the corresponding user's account ID;

[0032] And step C1 specifically is as follows:

[0033] C11. When the location information of the safety helmet is obtained, determine whether there are any field devices within the scope of the location location that are within the permission range of the account ID bound to the safety helmet;

[0034] C12. If it exists, extract, process, and package the file information of the device within the account ID permission range corresponding to the safety helmet, and put it in a ready-to-send state;

[0035] C2 specifically refers to: when the APP user with the account ID mentioned in C12 scans the KKS code of the corresponding field device, the corresponding file information to be sent will be sent to the APP user.

[0036] In the aforementioned thermal power plant archive information management system with high availability, step C1 is preceded by: the system server binding each safety helmet to the corresponding user's account ID;

[0037] Steps C1-C3 are replaced with:

[0038] When the location information of the safety helmet is obtained, it is determined whether there are any field devices within the permission range of the account ID bound to the safety helmet within the range of the location;

[0039] If present, the file information of the field devices within the scope of the account ID's permissions, located within the area of ​​the location, will be sent to the APP user of the account ID.

[0040] The advantages of this invention are:

[0041] 1. The management system uses KKS codes to associate the file information of the corresponding equipment. Users can accurately obtain the file information of the relevant equipment by scanning the KKS code of the equipment on site. It has the advantages of convenience, speed and accurate positioning.

[0042] 2. Integrate this system with the ERP system, and take advantage of the fact that the ERP system automatically carries KKS codes during the process, which can avoid the problem of errors that are easy to occur during code entry.

[0043] 3. Integrate this system with the training system and provide a training interface for the training system. Users can directly request relevant file information in the training system, helping them to quickly query and learn, and helping trainees quickly master various knowledge related to the equipment in conjunction with the on-site equipment, thereby assisting the training system and improving training effectiveness;

[0044] 4. Based on the integration of this system with the ERP and training systems, the system utilizes the equipment status information in the ERP system to proactively send maintenance equipment file information to the training users of the corresponding training system when the equipment is under maintenance. The disassembly of maintenance components and equipment exposes the internal structure, which is more conducive to employee learning. The combination of on-site physical knowledge and written knowledge helps employees understand and master the knowledge, thereby improving the training effect.

[0045] 5. The system APP not only has browsing function, but also borrowing function. Users can not only browse online, but also borrow documents for convenient and quick viewing at any time. It also provides independent APP storage space. Only the APP and the account requesting the borrowing can open the downloaded file information, which can provide convenience to users while meeting the document confidentiality requirements.

[0046] 6. Given that employees must wear safety helmets on site, and that most safety helmets are now equipped with sensors for location tracking, adding smart safety helmets to this system will allow for the preparation of relevant equipment file information by acquiring the helmets' location information. This will improve the efficiency of sending file information requests to on-site equipment. Attached Figure Description

[0056] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0057] This embodiment proposes a highly available information management system for thermal power plant archives, including a system server, an app installed on mobile terminals, and an application installed on a PC. The focus of this solution is on the mobile application; therefore, the PC version is not discussed in detail. The mobile application enables mobile access to archive information services via wireless networks and mobile terminals such as smartphones, extending archive retrieval from PCs to mobile devices and providing a new method for archive searching. Mobile searching is more flexible and convenient than PC searching, allowing for archive access anytime, anywhere at the work site. It's like everyone carries a treasure trove of equipment archive data, readily accessible and usable whenever needed.

[0058] The proposed thermal power plant information management system optimizes the use of archival information from the perspective of data usage. Considering the unique characteristics of thermal power plant archives, it enhances the ease of use of archival information from multiple angles, extending beyond collection, management, and storage to application. For on-site staff, they can quickly obtain archival information about field equipment by scanning the KKS code, without needing to perform targeted searches, know the equipment name or other information, or go to the warehouse. They can also accurately obtain the required archival information. For training staff, by integrating with the archival management system, they can directly obtain archival information about equipment related to their training. Furthermore, regardless of whether training staff have permissions for the relevant equipment, by integrating with the training system, as long as an employee's training involves a particular piece of equipment, they can obtain the archival information for that equipment by scanning the on-site equipment. Furthermore, this system incorporates the positioning function of safety helmets. At thermal power plants, employees are typically on-site for equipment maintenance, training, and inspection, frequently requiring access to equipment documentation. This solution, by integrating with safety helmets, can pre-retrieve relevant documentation from the server and send it directly to the user upon request, eliminating processing steps and significantly reducing request time and improving resource acquisition efficiency. Alternatively, the system can directly send the relevant documentation; the user simply receives the file, further enhancing the ease and intelligence of using equipment documentation.

[0059] Specifically, such as Figure 1 As shown, the system server is connected to a database for storing thermal power plant archives. These archives include equipment information, with each piece of equipment's information linked to its corresponding KKS (Knowledge, Skill, and Document) code in the database. When a user scans the KKS code of on-site equipment using an app, the app uploads the scanned KKS code to the system server. The system server then retrieves the corresponding equipment's archive information from the database based on the received KKS code and sends it to the app. The archive information that can be sent to the app can be all information related to the relevant equipment, such as certificates, test reports, manuals, maintenance documents, drawings, etc., directly related to equipment installation, use, maintenance, repair, and replacement. Alternatively, it can be partial information about the relevant equipment, specifically configured by administrators in the backend based on confidentiality requirements and other practical considerations.

[0060] Traditional archival systems typically require users to input keywords such as file number, title, year, responsible person, equipment name, and equipment model to browse or download archival information. However, regardless of the keyword used, incorrect information is prone to errors due to input mistakes, and the accuracy is insufficient. To address this, this solution proposes linking archival information to the equipment's KKS code. Users can then scan the KKS code on-site via an app to access the corresponding equipment's information, enabling a new model of proactively extending, advancing, and delivering archival utilization to the field. Furthermore, directly linking equipment KKS to archival information eliminates the need for manually pasting QR codes, avoiding the problem of excessive QR code usage and difficulty in finding the correct code. It also avoids maintenance issues arising from damage, additions, or replacements later on.

[0061] Furthermore, this solution integrates this system with the ERP system and synchronizes the device KKS codes from the ERP system. Leveraging the feature of the ERP system automatically carrying KKS codes during process flows, these KKS codes can be entered into this system, avoiding errors that are common during code entry.

[0062] Specifically, since the power plant's file system has confidentiality requirements, each employee needs to register an account. Each APP user who needs to use this system has a corresponding account that has been authenticated by the identity authentication platform. The system server records the account ID and job responsibilities of each APP user, and provides file access permissions for relevant equipment to the corresponding account ID according to the job responsibilities.

[0063] like Figure 2 As shown, when the system server receives the KKS code uploaded by the APP user, it identifies the APP user's account ID and determines whether the current APP user has access rights to the device corresponding to the current KKS code based on the account ID. If so, the device file information is sent to the APP user; otherwise, the sending is refused.

[0064] Furthermore, this solution preferably includes an electronic document browsing interface in the mobile app, allowing users to browse archive information via a URL.

[0065] Furthermore, such as Figure 3 As shown, this system interfaces with the training system. This system provides a training interface for training system users to request equipment training, including the following steps:

[0066] A1. Obtain the training users who participated in the training in the training system;

[0067] A2. Obtain the training content for each training user;

[0068] A3. Match each training user to users within this system, that is, match the training user with the account ID of users within this system. This can be done based on the user's registered identity information from both systems.

[0069] A4. Determine the corresponding field equipment for each training content; if the training system directly provides the corresponding field equipment, obtain it from the training system; if the training system does not directly provide the corresponding field equipment, determine the corresponding field equipment by analyzing the training content.

[0070] A5. Determine whether the APP user with the account ID mentioned in A3 has permission to access the field device mentioned in A4;

[0071] If not, grant the on-site equipment access permissions to the account ID regarding training records, then execute A6; otherwise, execute A6 directly. The on-site equipment records regarding training can be a portion of the equipment's organized records, or... Figure 1 , Figure 2 The file information that this system can send to authorized users, as described herein, may also be a part of it. Figure 1 , Figure 2 The system can send all the file information to authorized users.

[0072] A6. Record the relationship between the relevant training users and the on-site equipment;

[0073] A7. When a training user requests equipment training in the training system, send the corresponding file information of the field equipment associated with them, that is, send the file information related to the training;

[0074] When the APP user with the account ID mentioned in A3 scans the KKS code of the field device in A4, the APP user receives the corresponding file information of the field device, that is, the file information related to training.

[0075] When the training session ends, the association between the training user and the on-site equipment is terminated. At the same time, if the account ID associated with the training user does not have permissions for the on-site equipment, the user's permissions for the corresponding file information are revoked.

[0076] In this solution, even if an APP user does not have access to a device, as long as the device is in training mode within the training system, the APP user will have access to the device's file information for training purposes. The user can request device training through the training system's APP, or access the corresponding device's file information by scanning a QR code within the APP of this system. This enables training users to quickly grasp various relevant knowledge about the device by utilizing the file system in conjunction with the on-site equipment, thus assisting the training system and improving training effectiveness.

[0077] Furthermore, such as Figure 4 As shown, this system also interfaces with the ERP system and is used to perform the following steps:

[0078] B1. Identify equipment status based on the ERP system;

[0079] B2. When equipment is identified as being under maintenance, query the training users associated with it;

[0080] B3. Send the equipment maintenance file information to the training system for the training users associated with the maintenance equipment found in step B2, so that they can borrow or browse it online.

[0081] The app provides a borrowing portal, and the mobile device provides its own app storage space, controlled by the app, to store downloaded file information after a user requests to borrow a file. When a user requests to return a file, the corresponding file information is deleted from the app's storage space, and the system records information such as the download and return times. When the app is uninstalled, the corresponding app storage space is released, and the downloaded files are automatically returned. The system sends the file information borrowed through the app to the corresponding mobile device for download after encrypting it with the corresponding account ID and the app itself, ensuring that the file information in the app's storage space can only be opened by the app and the corresponding account ID.

[0082] Furthermore, such as Figure 5 and Figure 6 As shown, this system also includes a safety helmet with sensors. The sensors detect the positioning of the safety helmet and perform the following steps:

[0083] This system also includes a safety helmet equipped with sensors, which detect the helmet's location and execute the following steps:

[0084] C1. Extract, process, and package the file information of field equipment within the coverage area of ​​the positioning location, placing it in a ready-to-send state. The coverage area refers to a region centered on the positioning location, extending outwards by several diameters from the positioning location. The size of the coverage area is determined by those skilled in the art as needed. Currently, for employee safety and other factors, power plant employees must wear safety helmets when going to the site, and these helmets are already equipped with sensors capable of positioning. This solution utilizes the current intelligence of safety helmets. This system can directly connect to the safety helmet or interface with the management system where the safety helmet is located, obtaining the safety helmet's positioning information in real time from the management system. Positioning the safety helmet can be achieved through active positioning methods such as GPS, or passive positioning methods based on the installation location of the signal transceiver.

[0085] When the C2.APP user scans the KKS code of the field device described in C1, the corresponding file information to be sent will be sent to the APP user;

[0086] C3. When it is detected that the field equipment with the file information in the pending sending state has left the area covered by the safety helmet positioning position, the pending sending state of the relevant file information shall be released.

[0087] If a user wearing a safety helmet enters the site, the system will detect that the safety helmet has entered the site. If there are 5 devices within the scope of the user's visit, the server system will retrieve the file information of these 5 devices from the database in advance and put them in a ready-to-send state. In this way, when the user scans the KKS code of any of these 5 devices, the server can immediately send the file out without the need for extensive retrieval, extraction and data processing before sending.

[0088] In a preferred embodiment, a device can be installed at each site to activate the system's helmet positioning function. The system will only locate the helmet within the designated area. For example, a wireless receiver can be installed at each site. The receiver will detect the helmet when it enters its signal range and upload the detection result to the system server. The system server then determines the helmet's location based on the location of the wireless receiver. Alternatively, a signal transmitter can be installed at each site to activate the helmet positioning module, ensuring it only performs active positioning and uploads the data to the system server within that specific area.

[0089] In another embodiment, such as Figure 7 and Figure 8 As shown, before step C1, the system server binds each helmet to the corresponding user's account ID; that is, each user will have their own helmet, and the helmet is bound to the user's account ID through the helmet's tag. Whether the location is actively or passively located, the system will receive the tag information of the helmet being located, so it can determine its owner, that is, determine the corresponding account ID.

[0090] In this embodiment, step C1 specifically involves:

[0091] C11. When the location information of the safety helmet is obtained, determine whether there are any field devices within the scope of the location location that are within the permission range of the account ID bound to the safety helmet;

[0092] C12. If it exists, extract, process, and package the file information of the device within the account ID permission range corresponding to the safety helmet, and put it in a ready-to-send state;

[0093] C2 specifically refers to: when the APP user with the account ID mentioned in C12 scans the KKS code of the corresponding field device, the corresponding file information to be sent will be sent to the APP user.

[0094] If user X wears a safety helmet to a site, the system locates the helmet at that location. It then queries the area within which N devices are located, indicating they are within user X's authorized permissions (or, the permissions of user X's account ID). The system then retrieves the file information for these N devices from the database and places them in a pending-send state. If user X scans the KSS code of any of these N devices, the server can immediately send the file without extensive searching, extraction, or pre-send data processing.

[0095] In another embodiment, step C1 is preceded by the following: the system server binds each safety helmet to the account ID of the corresponding user;

[0096] like Figure 9 As shown, in this embodiment, steps C1-C3 are replaced with:

[0097] When the location information of the safety helmet is obtained, it is determined whether there are any field devices within the permission range of the account ID bound to the safety helmet within the range of the location;

[0098] If present, the file information of the field devices within the scope of the account ID's permissions, located within the area of ​​the location, will be sent to the APP user of the account ID. The user can simply receive the information, or it can be set to receive automatically.

[0099] If user X goes to the site wearing a safety helmet, the system locates the safety helmet at the site, and then queries the area within which the safety helmet is located. There are N devices within user X's permission range, or in other words, within the permission range of user X's account ID. The system then retrieves the file information of these N devices from the database and sends it to user X. At this time, the user only needs to receive it, or it can be set to receive it automatically.

[0100] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
