Core Features:
- Maintenance Plan Management: Support periodic maintenance plan formulation by time/operating hours
- Maintenance Task Assignment: Automatically or manually generate maintenance tasks and assign responsible persons
- Maintenance Execution Records: Record maintenance processes, results, and related data
- Equipment Maintenance Item Management: Define maintenance items and operation standards for different equipment
- Maintenance Reminders and Warnings: Automatically remind about upcoming or overdue tasks according to plans
- Maintenance History Traceability: Support query and analysis of equipment lifecycle maintenance records
2. Term Definitions
2.1 Equipment Maintenance Related Terms
| Term | Definition | Description |
|---|---|---|
| Equipment Maintenance | Regular maintenance and inspection activities performed on equipment | Including cleaning, lubrication, tightening, adjustment, etc. |
| Maintenance Cycle | Time or usage frequency interval for maintenance execution | Such as daily, weekly, every 100 operating hours |
| Maintenance Plan | Predefined maintenance arrangements in the system | Basis for automatic generation of maintenance tasks |
| Maintenance Task | A specific maintenance job to be executed | Triggered by plan or manually created |
| Maintenance Standard | Maintenance content specifications for each type of equipment | Includes steps, requirements, and judgment criteria |
| Maintenance History | Collection of historical maintenance records for equipment | Used to analyze equipment status and reliability |
3. Maintenance Management
3.1 Maintenance Plan Management
Maintenance plans define periodic maintenance rules for equipment and serve as the basis for generating maintenance tasks.
Plan Types:
| Type | Description | Example |
|---|---|---|
| Time Cycle | Execute at fixed time intervals | Daily/Weekly/Monthly |
| Operating Hours | Execute based on accumulated equipment operating time | Every 100 operating hours |
| Custom Cycle | Flexibly set execution rules | Every 3 days or every 500 units produced |
Field Description:
| Field | Description | Required |
|---|---|---|
| Plan Number | Unique identifier for maintenance plan | - |
| Equipment Number | Equipment requiring maintenance | Yes |
| Maintenance Type | Daily/Weekly/Monthly/Annual maintenance | Yes |
| Maintenance Cycle | Execution cycle rule | Yes |
| Maintenance Items | Corresponding maintenance content list | Yes |
| Responsible Person | Personnel or position responsible for execution | Yes |
| Enabled Status | Whether the plan is enabled | Yes |
3.2 Maintenance Task Generation
The system automatically generates maintenance tasks based on maintenance plans and also supports manual creation of temporary maintenance tasks.
Task Sources:
- Auto-generated: System triggers automatically by cycle
- Manually created: Created by administrator or equipment manager
- Exception triggered: Special maintenance triggered after equipment abnormality
Task Status:
| Status | Description |
|---|---|
| Pending | Generated but not started |
| In Progress | Maintenance is underway |
| Completed | Maintenance completed and recorded |
| Overdue | Not executed beyond planned time |
3.3 Maintenance Standard Management
Maintenance standards are used to standardize maintenance content and execution requirements for different equipment.
Maintenance Content Examples:
| Item | Content | Standard Requirements |
|---|---|---|
| Cleaning | Clean equipment surface dust | No obvious dust accumulation |
| Lubrication | Add lubricating oil to moving parts | Moderate oil level, no dry friction |
| Tightening | Check for loose screws | No looseness |
| Inspection | Check electrical/mechanical status | No abnormalities |
[Important] Maintenance standards should be uniformly developed by equipment engineering or process personnel to ensure consistency.
4. Maintenance Execution Operations
4.1 Maintenance Task Execution
Operation Steps:
- Navigate to [Equipment Management] → [Equipment Maintenance] → [Maintenance Tasks]
- Select the maintenance task to execute from the task list
- Click [Start Execution] button
- Complete maintenance content item by item according to maintenance standards
- Fill in maintenance results and remark information
- Click [Complete Maintenance] button to submit the record
Field Description:
| Field | Description | Required |
|---|---|---|
| Task Number | Unique number for maintenance task | - |
| Executor | Personnel actually performing maintenance | Yes |
| Execution Time | Start/end time of maintenance | Yes |
| Maintenance Result | Normal/Abnormal | Yes |
| Abnormality Description | If abnormal, fill in specific situation | No |
| Handling Measures | Abnormality handling method | No |
[Note] If abnormalities are found during maintenance, they should be recorded and reported immediately.
4.2 Maintenance Result Recording
After maintenance is completed, the system records detailed execution data for subsequent analysis.
Recording Content:
- Maintenance item execution status
- Abnormal points and handling results
- Actual execution time
- Executor information
[Tip] It is recommended to perform on-site recording on mobile terminals (PDA) to improve data real-time performance.
5. Maintenance History Query
5.1 Query Condition Settings
Query Conditions:
| Query Condition | Description |
|---|---|
| Equipment Number | Query specified equipment |
| Maintenance Type | Daily/Weekly/Monthly maintenance |
| Time Range | Maintenance execution time range |
| Executor | Specified personnel |
| Maintenance Result | Normal/Abnormal |
5.2 Query Result Display
Maintenance History Example:
| Date | Equipment | Maintenance Type | Executor | Result | Status |
|---|---|---|---|---|---|
| 2026-04-10 | Equipment A | Daily | Zhang San | Normal | Completed |
| 2026-04-12 | Equipment A | Weekly | Li Si | Abnormal | Processed |
[Tip] Click the record to view detailed maintenance content and abnormality handling process.
6. Maintenance Reminders and Warnings
6.1 Reminder Mechanism
The system automatically reminds relevant personnel according to maintenance plans:
- Upcoming reminder (advance notification)
- Same-day maintenance reminder
- Overdue non-execution reminder
6.2 Warning Rules
| Warning Type | Trigger Condition | Handling Suggestion |
|---|---|---|
| Overdue Warning | Not executed beyond planned time | Arrange execution immediately |
| Frequent Abnormalities | Multiple abnormalities during maintenance | Conduct equipment inspection |
| Long-term No Maintenance | No maintenance records | Check plan configuration |
[Important] Long-term non-execution of maintenance may significantly increase equipment failure risk.
7. Data Management Standards
7.1 Data Integrity Requirements
- All equipment must have maintenance plans configured
- All maintenance tasks must record execution results
- Abnormal situations must include handling measures
- Maintenance records must be associated with equipment numbers
7.2 Maintenance Management Rules
| Rule | Description |
|---|---|
| Plan Uniqueness | Only one maintenance plan of the same type for the same equipment |
| Execution Timeliness | Maintenance tasks should be completed on time |
| Data Authenticity | Maintenance records must be true and valid |
| Closed-loop Management | Abnormalities must have handling results |
[Note] Maintenance data is an important basis for equipment reliability analysis and must ensure accuracy.
8. Common Issues and Handling
8.1 Maintenance Abnormality Handling
| Issue Phenomenon | Possible Cause | Handling Method |
|---|---|---|
| Maintenance not executed | Personnel oversight | Supplement execution and strengthen reminders |
| Missing maintenance records | Not filled in timely | Supplement data entry |
| Abnormality not handled | Not reported | Handle immediately and close the loop |
| Frequent abnormalities | Equipment aging | Arrange inspection or replacement |
8.2 Maintenance Optimization Suggestions
- Establish standardized maintenance templates
- Use scanning/PDA for maintenance execution
- Regularly analyze maintenance data
- Link maintenance with equipment status
[Tip] It is recommended to combine with equipment status management to achieve predictive maintenance (PM).
