Heating Control System

A Streamlit-based application for controlling and monitoring industrial heating systems with OPC UA integration.

Features

• User Authentication: Secure login system using Streamlit Authenticator
• Dual Control Modes:
  • Simple Mode: Control heating with basic power and time parameters
  • Advanced Mode: Fine-tune with voltage, current, and frequency settings
• Real-time Monitoring: View system parameters including temperature, current consumption, and cooling metrics
• Configuration Management: Save, load, and delete heating configurations
• OPC UA Integration: Connect to industrial control systems via OPC UA protocol
• SQLite Database: Store configurations persistently

Installation

1. Clone this repository:

   git clone git clone https://github.com/destrohr/HMI_Pannel
   cd HMI_Pannel

2. Install required packages:

   pip install -r requirements.txt

3. Set up your access.yaml file for authentication:(optional)

   credentials:
     usernames:
       username1:
         email: user1@example.com
         name: User One
         password: hashedpassword1
       username2:
         email: user2@example.com
         name: User Two
         password: hashedpassword2
   cookie:
     name: heating_system_auth
     key: your_signature_key
     expiry_days: 30

4. Configure your OPC UA server settings:

   • Edit the OpcServerUrl variable in the code to point to your OPC server
   • Verify the node IDs match your OPC UA server structure

Usage

1. Run the application:

   streamlit run Web.py

2. Log in using credentials from your access.yaml file

3. Select operation mode (Simple/Advanced)

4. Configure heating parameters and toggle system state

5. Start/Stop heating process and monitor parameters

6. Save configurations for future use

System Requirements

• OPC UA Server running and accessible
• Python 3.7+
• Modern web browser

Development

The application structure follows a modular approach with separate functions for:

• Database management
• OPC UA communication
• UI rendering
• Configuration handling

If extending the application, follow the established pattern for new features.
