The HMI (Human-Machine Interface) refers to the medium or interface through which humans interact and exchange information with machines or systems. It is typically a visual interface that allows users to interact with machines or systems through graphics, text, sound, etc. The HMI aims to provide intuitive, easy-to-use, and efficient operation methods, enabling users to conveniently monitor, control, and manage the operation status and parameters of machines or systems.
An HMI typically consists of the following main components:
Display: HMIs typically use touchscreens or LCD displays as the interface for displaying the operation status, parameters, alarm information, and other content of machines or systems. The display can be monochrome, color, or high-resolution to provide a clear visual presentation.
Input Devices: HMI (Human Machine Interface) provides input devices such as touchscreens, buttons, switches, keyboards, etc., for receiving users' operation instructions. Users can input commands by touching buttons, sliders, switches and other controls on the screen or by pressing physical buttons, switches, etc., thereby controlling the operation of machines or systems.
Navigation and Menus: HMIs typically feature clear navigation and menu structures, enabling users to easily browse and operate different functional areas. Elements such as a navigation bar, menu bar, and toolbar can guide users quickly to the desired functions and settings.
Graphics and Charts: HMIs use graphics and charts to display the operation status and data of machines or systems. These graphics and charts can intuitively show the trend of changes in parameters such as temperature, pressure, flow rate, speed, etc., helping users quickly understand the overall operation of the system.
Alarm and Notification: The HMI (Human Machine Interface) provides alarm and notification functions to offer timely feedback when users need attention or action. When the system encounters abnormal conditions or reaches predefined thresholds, the HMI can display alarm messages, pop up dialog boxes, or generate audio notifications to attract users' attention.
Programming and Configuration: Some advanced HMIs also support programming and configuration features, allowing users to customize the interface layout, control functions, data display methods, etc. according to their needs. This enables users to tailor the HMI interface based on their operation habits and monitoring requirements, improving operational efficiency and convenience.
In summary, the HMI (Human-Machine Interface) serves as a medium for interaction between humans and machines or systems. Through intuitive, user-friendly, and efficient interface design, users can conveniently monitor, control, and manage the operation status and parameters of machines or systems.
