Abstract
Description
Technical Field
[0001] This invention relates to the field of factory equipment operation and maintenance management technology, specifically to a cigarette factory equipment operation and maintenance management system and a paperless management method. Background Technology
[0002] Equipment is the core carrier for ensuring production continuity and product quality, and its operation and maintenance management efficiency directly affects the production efficiency of enterprises. Currently, manufacturing enterprises have shifted from traditional models to systematic information management of equipment operation and maintenance, but two major shortcomings still exist: The management modules are fragmented: core maintenance tasks such as technical standard query, point inspection, equipment anomaly reporting, maintenance management, maintenance call, parts management, and maintenance and lubrication management are carried out through different methods such as paper records, verbal communication, and separate software, forming "information silos." Employees need to switch between multiple channels to operate, which is cumbersome and results in delayed information transmission, leading to low management efficiency.
[0003] Paperless implementation is lacking: Although most manufacturing enterprises adopt information management systems (such as the equipment management module of an MES system), key processes such as equipment inspection, parts requisition, and maintenance records still rely on paper records. Paper records are prone to loss, damage, and alteration, and require manual compilation, resulting in long cycles and significant errors.
[0004] In view of the above, in order to overcome the above technical problems, the present invention designs a cigarette factory equipment operation and maintenance management system and a paperless management method, which solves the above technical problems. Summary of the Invention
[0005] The technical objective of this invention is to provide a cigarette factory equipment operation and maintenance management system and a paperless management method to solve the problems of delayed response and inconsistent standards caused by the dispersed modules and reliance on paper in traditional operation and maintenance management.
[0006] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution: This invention provides a cigarette factory equipment operation and maintenance management system, including on-site operation terminals, back-end servers, maintenance team integrated dashboard terminals, office computers for each team, and switches; The on-site operation terminal is an industrial-grade touch screen computer, deployed on the production site, including a technical standard query module, a point inspection execution module, a maintenance record query module, and a maintenance call module; The technical standard query module is used to query various repair standards and maintenance manuals. The point inspection execution module receives the point inspection task list pushed by the system, which is used to guide the operator to carry out inspection work; the point inspection execution module initiates a maintenance request for non-conforming items based on the real-time entered inspection results, and the maintenance request is associated with the corresponding equipment location number and defect description. The maintenance call module is used to initiate maintenance calls and synchronize information to the maintenance team's integrated dashboard terminal in real time. The backend server includes a data storage unit, a data analysis unit, an information push unit, and a permission management unit; The data storage unit uses a relational database to store operation and maintenance data. The data analysis unit is used for statistical analysis of the maintenance data in the operation and maintenance data; The information push unit is used to automatically push each process plan to the corresponding personnel's office computers or on-site operation terminals. The permission management unit is used to assign corresponding operation permissions to different operators of the office computers, maintenance team integrated dashboard terminals and on-site operation terminals of each work group. The maintenance team's integrated dashboard terminal is deployed in the maintenance team's office area to visually display maintenance call information; The office computers in each work group are configured with different operating permissions according to the job positions. The switch is used to connect each terminal to the backend server.
[0007] Furthermore, the field operation terminal also includes a maintenance record query module and a lubrication record query module. The maintenance record query module queries detailed maintenance information by equipment location number, maintenance cycle, and maintenance type; the lubrication record query module is used to query the lubrication history of equipment components.
[0008] Preferably, the various maintenance standards and manuals include equipment technical parameters, maintenance procedures, troubleshooting manuals, and equipment improvement documents; the technical standard query module supports keyword search and category browsing, and has an offline caching function.
[0009] Preferably, the task list includes project name, execution method, execution standard, execution cycle, and execution workstation; the operation and maintenance data includes point inspection data, fault records, repair records, maintenance records, parts requisition records, user information, and permission configuration; The point inspection data includes qualified point inspection data and unqualified point inspection data; the parts requisition record includes parts consumption record and parts remaining record; the data storage unit supports scheduled automatic backup and manual backup, and the maintenance data retention period can be customized.
[0010] More preferably, the maintenance data includes maintenance records, fault records, parts consumption records, and non-conforming inspection data; the data analysis unit automatically generates periodic reports divided into daily, weekly, and monthly categories by statistically analyzing the maintenance data, and the core indicators of the periodic reports include fault type distribution, parts consumption trend, and equipment health status score; the information push unit pushes information via pop-up windows, SMS, and in-system messages.
[0011] Preferably, the operators include maintenance personnel, technicians, equipment specialists, and managers; in the access control unit, the permissions of maintenance personnel include entering maintenance records and submitting parts requests; the permissions of technicians include issuing maintenance plans, accepting maintenance and repairs, and drafting preliminary standards; the permissions of equipment specialists include revising technical standards, configuring system parameters, statistical analysis, and data backup; and the permissions of managers include querying records, viewing reports, approving parts requests, and approving maintenance plans.
[0012] The present invention also provides a paperless management method, based on the above-mentioned management system, comprising the following steps: Equipment codes are uniquely assigned to each piece of equipment according to the "production line-serial number" rule; equipment structures are decomposed according to the "model-subsystem-location-component-part" hierarchy; point inspection standards are compiled according to the "project name-execution method-execution standard-execution cycle-execution station"; lubrication standards are compiled according to the "lubrication location-oil type-method-cycle-execution station"; maintenance and repair standards are compiled by part according to the "project-standard-cycle-execution station"; thus, basic data consisting of equipment codes, structural decomposition, and various standards is obtained. Import basic data into the backend server through batch import or manual entry, and configure user accounts, role permissions and system parameters on the backend server; The entire process, including point inspection, maintenance management, spare parts application, planned maintenance, abnormal maintenance, maintenance call, and lubrication management, is executed. The entire process is carried out through automatic work order push by the system, personnel execution and data entry, and multi-level acceptance and archiving. The backend server connected to the switch stores the data of the entire process in real time and automatically generates statistical reports.
[0013] Furthermore, the point inspection process includes: The system pushes the inspection task list to the on-site operation terminal according to the preset cycle. The personnel enter the inspection results, qualified items are automatically archived, and unqualified items trigger abnormal reporting and automatically generate maintenance request forms. The maintenance request forms include equipment location number, inspection items, defect description, defect level, discovery time and suggested measures. At the same time, the system pushes the information to maintenance personnel, technicians and team leaders to achieve three-level information synchronization.
[0014] Furthermore, the maintenance call process includes: Operators can initiate a call with one click by selecting the faulty equipment and fault type through the on-site operation terminal. Fault types include equipment shutdown, abnormal equipment noise, equipment oil leakage, abnormal temperature, abnormal pressure, and electrical fault. When the maintenance team's integrated control panel receives a call, it triggers an audible and visual alarm, and the team leader assigns a maintenance worker to the task. The system automatically calculates the response time after the repairman arrives and confirms the situation. If a fault cannot be resolved on the spot, it will automatically be transferred to the planned maintenance process; if it can be resolved on the spot, the fault will be archived directly.
[0015] Meanwhile, the planned maintenance process includes: Technicians issue maintenance work orders based on maintenance standards and equipment data, specifying the equipment to be repaired, the items to be repaired, the maintenance cycle, and the responsible person. After performing the repair, the repairman enters the repair record, including fault cause analysis, repair solution selection, repair step description, repair process photos, replacement parts information, and test result data; During acceptance testing, technicians verify the achievement of maintenance objectives, compliance of equipment parameters, compliance of maintenance quality, and completeness of records. Monthly maintenance performance analysis reports are generated, including completion rate, average time, quality pass rate, recurring failure rate, cost statistics, and improvement suggestions.
[0016] The beneficial effects of this invention are as follows: 1. This invention enables real-time fault reporting and automatic work order generation through the point inspection execution module and maintenance call module of the on-site operation terminal. The back-end server stores and analyzes data based on a relational database and automatically pushes tasks, so that the information collection, task assignment and result archiving on the production site form an automatic cycle, which significantly reduces the error of manual transmission and the problem of information lag, improves the equipment maintenance response speed and the integrity of operation and maintenance data, thereby effectively improving the stability of cigarette factory equipment operation and management efficiency.
[0017] 2. This invention achieves traceable management of equipment lubrication and maintenance data by setting up maintenance record query modules and lubrication record query modules, and binding them to equipment location numbers and maintenance cycles. The system can automatically retrieve relevant historical records during point inspections, maintenance, and repair processes, forming a time-axis-based equipment maintenance archive. This allows for accurate identification of frequently failing equipment and weak points in maintenance during data analysis. It enables dynamic optimization of equipment maintenance plans, thereby improving the scientific nature of equipment management and the level of predictive maintenance.
[0018] 3. This invention achieves automated work order delivery and multi-level acceptance archiving mechanism throughout the entire process, centered on equipment coding, structural decomposition, and a standard system, through a paperless management approach. The system can automatically generate maintenance request forms based on inspection results, and fault types are synchronized to the maintenance team's integrated dashboard terminal, realizing full-process digital linkage from fault detection, task assignment, maintenance execution, to acceptance confirmation. This achieves a management transformation from "reactive maintenance" to "prevention," improving the intelligence and precision of equipment operation and maintenance in cigarette factories. Attached Figure Description
[0019] To more clearly illustrate the specific embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the specific embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.
[0020] The above and other aspects of the invention will now be described by way of example only, with reference to the accompanying drawings, in which: Figure 1 This is a schematic diagram of the module connections of the management system according to an embodiment of the present invention. Detailed Implementation
[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods. Example
[0022] like Figure 1 As shown in this embodiment, a centralized equipment operation and maintenance management system is applied in the tobacco processing workshop of a large cigarette factory. The system consists of on-site operation terminals, a back-end server, a comprehensive dashboard terminal for maintenance teams, office computers for each team, and an industrial-grade switch. The five components are connected to a local area network via an industrial Ethernet network to achieve real-time data interaction, ensuring stable and reliable communication.
[0023] The on-site operation terminal is deployed in key process stages such as blade manufacturing, leaf filament manufacturing, and fragrance application. It utilizes an industrial-grade touchscreen computer and is waterproof, dustproof, interference-resistant, and resistant to high and low temperatures. It can operate stably within an ambient temperature range of 0–45℃, supporting all-weather operation. The on-site operation terminal includes built-in modules for technical standard query, point inspection execution, maintenance record query, maintenance call, maintenance record query, and lubrication record query.
[0024] The technical standards query module integrates equipment technical parameters, maintenance procedures, troubleshooting manuals, and equipment improvement documents. It supports keyword search and categorized browsing, and has an offline caching function, allowing users to view cached documents even when offline. The inspection execution module receives inspection task lists pushed by the system, including items, methods, standards, cycles, and execution workstations. Operators, mechanical repairmen, and electricians execute tasks according to their roles and record inspection results in real time. For non-conforming items, repair requests can be initiated directly, and the system automatically associates the equipment location number with the defect description.
[0025] The maintenance record query module supports multi-condition queries, including searching daily maintenance, planned maintenance, and periodic maintenance records by equipment location number, maintenance time, and maintenance type, and displays the maintenance content, handler, and acceptance results. The maintenance call module allows users to initiate equipment fault calls with a single click via the on-site operation terminal, with information synchronized in real-time to the maintenance team's integrated dashboard terminal. The maintenance record query module allows users to search historical maintenance information by equipment location number, maintenance cycle, and maintenance type, displaying maintenance items, performers, and acceptance results. The lubrication record query module is used to query the lubrication history of various equipment components, including lubricant type, operation time, and method.
[0026] Each work team's office computer is configured with permissions according to their position. Maintenance personnel have the authority to enter maintenance records and submit spare parts requests. Technicians can issue maintenance plans and conduct maintenance and acceptance tests. Equipment specialists have the authority to revise technical standards, configure system parameters, and back up data. Management personnel can query records, view reports, and approve related applications.
[0027] The backend server is deployed in the enterprise's data center. The data storage unit uses a relational database to store inspection data, anomaly information, maintenance records, repair records, parts requisition records, and user information. It supports scheduled automatic backups and manual backups, and the data retention period can be customized. The data analysis unit performs statistical analysis on maintenance records, fault records, parts consumption records, and non-conforming inspection data, automatically generating daily, weekly, and monthly reports, including fault type distribution, parts consumption trends, and equipment health status scores.
[0028] The information push unit automatically pushes inspection tasks, maintenance request forms, maintenance plans, lubrication plans, and approval notices to the corresponding personnel's on-site operation terminals or office computers according to preset rules. The access control unit adopts a role-permission mapping mechanism, dividing roles according to job positions, supporting preset basic permission templates and custom configurations to prevent accidental operation and information leakage. The maintenance team's integrated dashboard terminal is deployed in the maintenance team's office, visually displaying maintenance call information and processing progress, and providing audible and visual alarm reminders to ensure timely maintenance response.
[0029] Industrial-grade switches connect all terminals to the backend server, ensuring the stability of local area network communication and the ability for multiple terminals to access concurrently. This system enables end-to-end information management of point inspection, maintenance, upkeep, and lubrication processes, eliminating paper records, improving data integrity and traceability efficiency, significantly shortening maintenance response time, reducing equipment downtime, and ensuring production continuity.
[0030] Example 2: Based on Embodiment 1, this embodiment provides a paperless management method for equipment operation and maintenance based on the above-mentioned management system, which is used to standardize the basic data of equipment.
[0031] All equipment is uniquely coded according to the "production line-serial number" rule, which serves as the equipment location number to ensure accurate identification. The equipment structure is decomposed according to the "model-subsystem-part-component-part" hierarchy. Taking the shredder of the leaf filament production line as an example, it is decomposed into "shredder-transmission subsystem-main shaft part-main shaft component-bearing parts".
[0032] The inspection standards are compiled according to the format of "item-method-standard-cycle-execution station". For example, the inspection standard for bearing temperature is "item: bearing temperature; method: infrared thermometry; standard: ≤60℃; cycle: once every 2 hours; execution station: maintenance worker".
[0033] The lubrication standard is formulated based on the five principles of lubrication, which clearly define the lubrication points, oil types, lubrication methods and execution cycles. For example, the gearbox uses No. 46 anti-wear hydraulic oil for oil bath lubrication once a month, which is performed by the maintenance worker.
[0034] The maintenance standards are based on parts, clearly defining maintenance items, standards, cycles, and work stations. For example, gear replacement requires a meshing clearance of ≤0.2mm, to be done once every 12 months, and to be performed by a mechanical maintenance worker.
[0035] The maintenance standards are compiled on a part-by-part basis, clearly defining the maintenance items and standards. For example, the filter element cleaning requirements are that the filter element is not clogged and its surface is clean, and it should be done once a week by the operator.
[0036] Basic data can be imported into the backend server in batches via office computers. It supports Excel format and manual entry. After import, batch modifications and individual adjustments can be made.
[0037] Configure user accounts, role permissions, and system parameters on the backend server, including data backup cycles and information push methods (pop-ups, SMS, in-site messages), to ensure that the system can operate flexibly according to enterprise management needs and achieve full-process data traceability.
[0038] Example 3: Based on Example 2, the operation process of each module is described in the following examples.
[0039] In the point inspection process, the system pushes inspection tasks to the on-site operation terminal according to a preset cycle. The operator completes the inspection and enters the results. Qualified items are automatically archived, and unqualified items trigger an abnormality report. The system automatically generates a maintenance request form and pushes it to maintenance personnel and management personnel to achieve three-level information synchronization.
[0040] In the equipment maintenance management process, the system automatically generates maintenance work orders. The personnel perform the maintenance operations and enter the details. The workshop technician or maintenance team leader then accepts the work orders. Unqualified work orders are returned for rectification and the reasons are recorded, thus realizing closed-loop maintenance management.
[0041] In the spare parts application management process, maintenance workers submit spare parts application forms, which are then reviewed by technicians and approved by workshop leaders to generate spare parts plans. The system records the requisition information, and the back-end server automatically updates the inventory and requisition records, making spare parts information transparent.
[0042] In the planned maintenance management process, the technician issues a planned maintenance work order, the maintenance team leader assigns tasks, the maintenance worker executes the work, enters maintenance records and uploads photos of the maintenance process and test data, and the technician conducts acceptance and archives the work.
[0043] The routine abnormal maintenance process and maintenance call process enable one-click reporting of fault information, audible and visual alerts, task allocation and response time recording. Faults that cannot be resolved on the spot are automatically transferred to the planned maintenance process.
[0044] The lubrication management process automatically generates lubrication work orders according to a preset cycle. These work orders are executed by designated personnel who then input the operation details. Once the work is accepted, the work orders are archived. Through this process, the system achieves paperless management of the entire equipment operation and maintenance process, ensuring data integrity, traceability feasibility, and operational monitorability. Maintenance response time is reduced by more than 40%, equipment downtime rate is reduced to below 0.13%, and data accuracy reaches 99.5%, significantly improving production continuity and management efficiency.
