In recent years, an increasing number of industrial and consumer products have been produced with internet connectivity capabilities. These products are operated using software called Human Machine Interface (HMI) programming. An HMI describes any type of software or device that allows humans to interact with machines. There are simple and complex forms of HMIs, such as a single touch display, a multi-touch control panel, or mobile technology.
HMIs facilitate efficient manufacturing operations by providing real-time information on machinery’s operating conditions. They allow for close monitoring of production and provide improved system diagnostics. HMIs can also use trending or historical data to illustrate areas where system improvements can be made. With the Internet of Things (IoT) technology connecting an increasing number of devices, HMI solutions are becoming increasingly popular.
Types of Human-Machine Interfaces (HMIs)
So, what is an HMI and what does it look like? There are three basic types of HMIs:
- The data handler: This type features a display screen large enough to show visual data representations, such as graphs. It is used in applications that require constant monitoring and include large-capacity memories.
- The pushbutton replacer: This HMI replaces mechanical buttons and switches with a centralized control panel that represents multiple devices on an LCD screen. It streamlines manufacturing processes by controlling any mechanical device from one location.
- The overseer: Overseer HMIs monitor and control large systems that operate in large areas. They are typically run using Windows operating systems and process control software – i.e. Emerson, Wonderware – and provide diagnostic and trending data as well as management information.
While these three types of HMI systems differ in purpose and operating technique, they are comprised of three basic components. In all HMI systems, a control panel is used to operate IoT-connected devices and a display visually represents buttons and switches or illustrates data points. An optional component included in many but not all HMI systems is a human-machine interface touchscreen that facilitates IoT device control.
Advantages of Human-Machine Interfaces (HMIs)
HMI technology provides many benefits to manufacturing and industrial applications. Some of the most significant advantages include:
-
- Ease of use: HMIs are developed to simplify operating conditions by implementing intuitive functionality such as drag-and-drop tools, templates, and the ability to tailor the system to your liking.
- Highly efficient: HMIs significantly increase system efficiency by connecting systems of machines, people, and data, typically resulting in reduced production costs.
- Remote monitoring: HMIs provide the ability to monitor machines in real-time and remotely, reducing labor costs by eliminating the need for onsite monitoring after hours.
- Detailed insights: These systems provide insights allowing users to respond quickly to conditions, reducing downtime.
- Improve processes and profitability: All of the previously mentioned benefits ultimately allow operators to quickly identify issues and make improvements, increasing productivity and profitability.
Applications of Human-Machine Interfaces (HMIs)
HMIs increase the efficiency and reliability of machinery used throughout diverse industries and have an extensive number of applications. Some of the most common applications for HMIs include visual data display and tracking production time. Some of the industries where HMIs are especially prevalent include:
- Automotive: Used for in-car touchscreens to control infotainment and satellite navigation systems.
- Aerospace: HMIs play a vital role in safety-critical aerospace applications, connect crew to the aircraft and passengers, and provide data that supports mission activities.
- Pharmaceutical: Used in patient monitoring systems, infusion pumps, dialysis machines, and many more applications, such as in pharmaceutical manufacturing plants and inventory management applications.
- Manufacturing: HMIs connect, monitor, and control manufacturing technology from a single access point, providing real-time status updates.
- Military and defense: HMIs increase the reliability of military monitoring equipment and are used in navigation, vehicle control, and vessel automation applications.
- Oil and gas: Used in petrochemical refining plants to monitor and control processing equipment. HMIs are also used for measurement while drilling in energy exploration.
- Food and beverage: HMIs provide data analysis and facilitate the control of diverse equipment for the food and beverage industry. They also promote safety and hygiene in food packaging and processing.
- Control rooms: HMIs provide a simplified control room system that enables greater monitoring and ease of use.
