About

This repository contains a Python-based system for controlling a punch machine (or a simulated punch process). It is structured to separate core logic, services, utilities, and configuration, and includes example entry scripts (main.py and simple-main.py). The project is designed to be extended with AI capabilities (vision-based monitoring, anomaly detection, predictive maintenance) and hardware communication (serial/USB/ethernet interfaces to PLCs, microcontrollers, or industrial controllers).

Key features

  • Modular architecture with clear separation between core logic, services, and utilities.
  • Example entry points:
    • simple-main.py — lightweight/demo entrypoint to get started quickly.
    • main.py — intended for full system startup and orchestration.
  • Support for environment configuration via .env and config/ directory.
  • Static assets directory for web UIs or dashboards (static/).
  • Extensibility points for AI models (vision, anomaly detection), hardware drivers, and web or API integration.
  • Requirements list for reproducible environments (requirements.txt).

Technologies & libraries

(Use depending on which modules you enable; typical stack)

  • Language: Python 3.8+
  • Web/API: Flask or FastAPI (if web interface is implemented)
  • Computer Vision: OpenCV, scikit-image
  • Machine Learning: TensorFlow or PyTorch, scikit-learn
  • Data & Persistence: SQLite / PostgreSQL, pandas
  • Hardware: pyserial for serial communication, RPi.GPIO for Raspberry Pi, minimal OPC-UA/Modbus libraries for PLC integration
  • Dev & Packaging: pip, virtualenv / venv, Docker (optional)

Skills & expertise demonstrated

  • Python application architecture and modular design
  • Real-time system integration (hardware-software interfaces)
  • Basic AI/Computer Vision pipeline design for monitoring and detection
  • Configuration and environment management (.env, config)
  • Logging, error handling, and safe shutdown for hardware control loops
  • Packaging and dependency management (requirements.txt)

Architecture overview

  • main.py — full orchestrator that initializes services and runs the control loop.
  • simple-main.py — simplified example for local testing and quick demos.
  • core/ — contains core business logic and controllers that implement the punch system behavior.
  • services/ — drivers and services (hardware interface, model inference, data persistence).
  • utils/ — helper functions, common utilities, and shared modules.
  • config/ — configuration templates and sample configs.
  • static/ — static web assets for dashboards or UIs.

Installation (local, Linux/macOS/Windows)

  1. Clone the repository git clone https://github.com/TariqMehmood1004/System-Controlling-Punch-System-Python-AI.git
  2. Create a virtual environment and activate it python -m venv venv source venv/bin/activate (Linux/macOS) venv\Scripts\activate (Windows)
  3. Install dependencies pip install -r requirements.txt
  4. Set up configuration
    • Copy .env.example (or create .env) and set keys as needed (see Configuration below).
    • Populate config/ files with correct hardware addresses, model paths, and DB settings.

Configuration (.env and config/)

  • The repo contains a .env file. Keep secrets and sensitive configuration out of version control (use .env locally and CI secrets in deployment).
  • Typical environment variables:
    • APP_ENV=development|production
    • LOG_LEVEL=INFO|DEBUG
    • MODEL_PATH=/path/to/model
    • SERIAL_PORT=/dev/ttyUSB0 or COM3
    • DB_URL=sqlite:///punch_logs.db
  • Example config/ sub-files:
    • hardware.yaml — pinout, communication settings
    • model.yaml — model type, input size, thresholds
    • dashboard.yaml — UI settings and refresh intervals

Running

  • Quick demo (simple) python simple-main.py This runs a simplified control loop (safe for demo mode / simulation).
  • Full run (production) python main.py Ensure .env and config are populated and hardware drivers are available. main.py should start services, load AI models, initialize communication, and begin monitoring/controlling the punch system.

Example usage scenarios

  • Start the system in simulation mode to validate control algorithms without connecting hardware.
  • Enable vision module to inspect each punch cycle and detect misfeeds or misalignment.
  • Log cycle metrics (force, speed, position) to a database for later analysis.
  • Use anomaly detection model to predict faults and trigger maintenance alerts.

How it works (high level)

  • Initialization: main.py boots the application, reads configuration, initializes logging and services.
  • Hardware driver: a service connects to the punch machine controller (via serial, Modbus, or a microcontroller bridge).
  • Decision loop: core controller reads sensors, runs safety checks, uses AI models (if enabled) to detect anomalies, and sends actuation commands.
  • Monitoring & logging: status, errors, and telemetry are persisted and optionally displayed via a local dashboard.

Common problems and how to overcome them

  • Problem: Hardware connection fails (serial/COM)
    • Check the device path/COM port and permissions. On Linux, add your user to groups like dialout or use sudo for debugging.
    • Confirm baud rate and serial parameters match the device.
  • Problem: Model file missing or incompatible
    • Verify MODEL_PATH in .env and that the model matches the expected framework (TensorFlow/PyTorch).
    • Provide a small fallback or simulation model for testing.
  • Problem: Unexpected machine behavior during testing
    • Always run first in simulation or with safety interlocks enabled.
    • Implement and test emergency stop and watchdog timers to prevent damage.
  • Problem: Permissions and environment differences across machines
    • Provide Dockerfile or development container to standardize the environment.
    • Use requirements.txt pinning and CI to test reproducibility.
  • Problem: High latency in real-time control
    • Move heavy inference to a separate thread/process or dedicated edge device (e.g., Jetson/NVIDIA device) and keep the control loop lightweight.

Real-world applications

  • Small-to-medium manufacturing lines using punch presses, stamping machines, or forming machines.
  • Education and R&D: safe simulation and testing environment for control and AI research.
  • Retrofitting older machines with modern monitoring and predictive maintenance capabilities.
  • Remote monitoring and logging for process traceability and QA.

Extending the project

  • Add a web UI (Flask/FastAPI + a React/Vue/JS dashboard in static/) to visualize status and control manually.
  • Implement or integrate ML models for:
    • Visual defect detection using camera frames.
    • Vibration analysis for early fault detection.
    • Cycle-time prediction and throughput optimization.
  • Add communication adapters for common industrial protocols:
    • Modbus TCP/RTU, OPC-UA, MQTT.
  • Add robust testing: unit tests, hardware-in-the-loop tests, and CI pipelines.

Testing recommendations

  • Unit-test core logic without hardware by mocking services.
  • Use an integration test suite with hardware simulators or recorded logs.
  • Introduce a gated deployment process for pushing changes to production machines.

Security & safety

  • Sensitive credentials and keys must not be committed. Use .env and secret management solutions.
  • Always validate incoming data from hardware and network interfaces.
  • Implement machine-level safety systems and fail-safe mechanisms (e.g., E-stop, watchdog).
  • Follow the SECURITY.md guidelines included in this repo.

Contribution & roadmap

  • Add clear contribution guide and issue templates.
  • Roadmap ideas:
    • Dockerization for easier deployment
    • Microservice split (separate inference service)
    • ML model training pipeline and dataset examples
    • Example hardware drivers (Raspberry Pi + Arduino examples)
