# Thiết Kế HMI Hiệu Quả - Best Practices Và Tips Human Machine Interface (HMI) là giao diện quan trọng giữa operator và máy móc. ## Nguyên Tắc Thiết Kế ### 1. Simplicity - **Ít** là **nhiều** - **Tránh** clutter - **Focus** vào thông tin quan trọng ### 2. Consistency - **Unified** color scheme - **Standard** button sizes - **Consistent** navigation ### 3. Visibility - **High contrast** colors - **Readable** fonts (min 12pt) - **Clear** status indicators ## Layout Best Practices ### Screen Organization: ``` Header: Title, Time, Alarms Main Area: Process graphics Footer: Navigation, Status ``` ### Color Coding: - **Red**: Alarms, Emergency stop - **Yellow**: Warnings, Attention - **Green**: Normal operation, OK - **Blue**: Information, Manual mode - **Gray**: Inactive, Disabled ## Navigation Design ### Menu Structure: ``` Main Menu ├── Production │ ├── Auto Mode │ ├── Manual Mode │ └── Recipe Management ├── Maintenance │ ├── Diagnostics │ ├── Calibration │ └── Service Menu └── Settings ├── User Management ├── Network Config └── Backup/Restore ``` ### Button Design: - **Minimum** 40x40 pixels - **Clear** labels - **Visual** feedback on press - **Disabled** state visible ## Alarm Management ### Alarm Priorities: 1. **Critical**: Process shutdown 2. **High**: Immediate attention 3. **Medium**: Action required 4. **Low**: Information only ### Alarm Display: ``` [TIMESTAMP] [PRIORITY] [MESSAGE] [ACK] 12:34:56 CRITICAL Motor 1 Fault [ACK] 12:35:12 HIGH Temp High [ACK] ``` ## Data Visualization ### Trends: - **Real-time** data plots - **Historical** data access - **Zoom** and **pan** capabilities - **Export** functionality ### Gauges: - **Analog** for continuous values - **Digital** for precise readings - **Color bands** for ranges - **Min/Max** indicators Ai đã thiết kế HMI chưa?
