Overview

This lecture introduces Human Machine Interface (HMI), explaining its functions, industrial uses, and the key benefits of implementation.

What is HMI?

  • HMI stands for Human Machine Interface and refers to a dashboard or screen for machinery control.
  • Information on HMIs is displayed graphically using icons, sounds, pictures, and colors.
  • HMIs provide real-time status updates and operating conditions of machinery.

Industrial Applications of HMI

  • HMI is used in manufacturing, energy, oil and gas, power, recycling, food and beverage, water and wastewater, transportation, pharmaceutical, and biotech sectors.
  • In transportation, HMIs serve as passenger access systems with illuminated buttons, indicators, and signaling devices.

Benefits of HMI Implementation

  • Increased Visibility: Centralizes data on equipment or machine performance in one place.
  • Enhanced Efficiency: Employees use real-time data to monitor and adjust production processes.
  • Decreased Downtime: Centralized dashboards show alerts and issue details, speeding up response.
  • Improved Usability: HMIs simplify monitoring and control tasks for facility staff.
  • Cost Reduction: HMI software helps reduce operating expenses by optimizing processes.

Key Terms & Definitions

  • HMI (Human Machine Interface) — A graphical dashboard or screen used for controlling and monitoring machinery.
  • Centralized Dashboard — A single interface that collects and displays data from across a system or facility.

Action Items / Next Steps

  • Review examples of HMI in your daily life or industry.
  • Be prepared to discuss or reflect on personal experiences with HMI systems.
