System Overview
Process Vision is a process monitoring and video recording system designed for laboratory process management.
Key Features
- Process Monitoring: Real-time display of temperature and pressure controller PV (process value), SV (set value), and output percentage
- Recipe Management: Create, edit, and manage process recipes, then download them to controllers
- Video Recording: Automatic or manual video recording during processes for later review
- Historical Data Query: Query and export historical process data with chart visualization
- Automatic Data Logging: Automatically records temperature, pressure, and other data to CSV files during processes
Main Window Layout
Left Navigation Panel
The navigation panel is organized into four sections:
| Section | Menu Items |
|---|---|
| Process | Process Monitor |
| Recipe | Recipe Editor |
| Data | History Query |
| Settings | Device Configuration, About |
Center Dashboard
- Process Status Card: Shows the current process state (Idle / Running / Paused / Completed / Error), session code, and progress percentage
- Temperature Card: Displays temperature PV, SV, and Output values
- Pressure Card: Displays pressure PV, SV, and Output values
- Quick Actions: Start/Stop process buttons
- Chart Area: Real-time data trend chart
Status Bar
Displays the system time, current operation messages, and process state.
Core Concepts
Recipe
A recipe defines the execution steps for a process, including target temperature, target pressure, duration, and output limits for each step. Each recipe supports up to 8 steps.
Recipes have three states:
- Draft: Editable but cannot be used for processes
- Active: Can be selected for process execution
- Archived: No longer in use
Process
A process is a single execution of a recipe. When a process starts, a session is created to track the operator, recipe, start time, and other details.
Process State
| State | Description |
|---|---|
| Idle | Waiting to start |
| Running | In progress |
| Paused | Temporarily paused |
| Completed | Finished successfully |
| Error | An error occurred |
Controller
The system connects to TAIE FC series PID controllers via the Modbus protocol:
- Temperature Controller (Slave Address 1): Controls heating/cooling
- Pressure Controller (Slave Address 2): Controls pressure
Language Switching
The language selector in the upper-right corner of the main window supports Traditional Chinese and English. The interface updates immediately upon switching.
