Design Ideas and Principles of Industrial HMI

The human-machine interface is the product of the combination of computer science and cognitive psychology. It also absorbs the research results of linguistics, ergonomics, and sociology. After more than 40 years of development, it has become one of the mainstream disciplines characterized by the study of users and their relationship with computers. In the field of industrial automation, factories have special requirements and design guidelines for man-machine interfaces.

Industrial man-machine interface design mainly includes three aspects:

(1) Design the interface between software components

(2) Design module and other non-human information producer and consumer interface

(3) Interface between designer (such as user) and computer

Industrial man-machine interface design ideas

Computers act according to the characteristics of machines, and people think and act in their own way. It is necessary to transform people's thinking and behavior into a way that machines can accept, and transform the way of machine behavior into ways that adults can accept. This transformation is the human-machine interface. To make the computer adapt to the human's thinking and action characteristics on the human-machine interface, this is the "people-oriented" man-machine interface design idea.

A friendly and beautiful interface will bring comfortable visual enjoyment to people, shorten the distance between people and the computer, and create selling points for businesses. The interface design is not a pure art painting, it needs to locate the user, use environment, use method and design for the end user. It is a pure scientific art design. The standard for testing an interface is neither the opinion of a project development team leader nor the result of voting by project members, but the feelings of the end user. Therefore, interface design must be closely integrated with user research, which is a process of continuously designing satisfactory visual effects for end users.

Principles of Industrial Human-Machine Interface Design

And release some control information to guide the operation of the field system. Therefore, they have higher requirements for the intuitiveness and friendliness of the human-machine interface, and the following principles should be considered in the design of the man-machine interface.

1. User-centric basic design principles

In the design process of the system, the designer must grasp the user's characteristics and discover the user's needs. In the whole development process of the system, users' opinions should be continuously sought and consulted. The system design decision must be combined with the user's work and application environment, and the user's requirements for the system must be understood. The best way is to involve real users in the development, so that developers can correctly understand the needs and goals of users, and the system will be more successful.

2. Order principle

That is, in accordance with the sequence of processing events, the order of access and viewing (such as from the whole to the single item, from the upper to the lower, from the upper to the lower, etc.) and the control process, the main interface for monitoring management and man-machine dialogue and its secondary interface are designed .

3. Functional principle

That is, according to the specific functional requirements of the target application environment and occasions, various subsystem control types, the same interface parallel processing requirements of different management objects, and the simultaneity requirements of multiple dialogue interactions, the design is divided into functions to distinguish multi-level menus and hierarchical prompts. The human-computer interaction interface such as the window with information and multiple dialog boxes simultaneously makes it easy for users to distinguish and master the rules and characteristics of the interaction interface, and improve its friendliness and ease of operation.

4. The principle of consistency

Including the consistency of colors, the same operating area, and the same text. That is, on the one hand, the color, shape, and font of the interface are consistent with national, international or industry common standards. On the other hand, the interface colors, shapes, and fonts are self-contained, and the colors of different devices and the same design state should be consistent. The consistency of the graphic design of the interface details makes the operator feel comfortable when looking at the interface, so as not to distract him. For new operators, or operators dealing with problems in an emergency, consistency can also reduce their operational errors.

5. Frequency principle

That is to design the hierarchical sequence of the man-machine interface and the display position of the dialogue window according to the dialogue interaction frequency of the management object, so as to increase the frequency of monitoring and access dialogue.

6. Materiality Principle

That is, in accordance with the importance and overall level of the management object in the control system, design the position and prominence of the main and sub-menus and dialog windows of the man-machine interface, so as to help managers grasp the priority of the control system and implement the control The sequence of decision-making to achieve optimal scheduling and management.

7. Object-oriented principles

That is, according to the operator's identity characteristics and work nature, design a suitable and friendly man-machine interface. According to its work needs, prompts, guidance and help information should be displayed in pop-up windows to improve the level and efficiency of user interaction.

The human-machine interaction interface, whether it is for on-site controllers or for upper-level monitoring and management, there is a close internal connection between the two. The objects they monitor and manage on-site are the same, so many on-site equipment parameters are shared between them And passed on to each other. Various industrial control configuration software and programming tools provide powerful support means for making exquisite human-computer interaction interfaces. The larger and more complex the system, the more it can reflect its superiority.
Hello ..
That's a nice article...
You have picked up on a very key point can have the high-quality written software on the PLC and superb hardware but if the user interface is not ok, then the conclusion is the system is not OK.
Carl you are 100% true.
The user interface is what the customer sees. So when that is ALSO perfect.............
That's why I develop many temperature control systems using Japanese Pro-face touchpanels programmed with GP Pro EX in combination with Japanese high quality RKC Instrument temperature controllers.
Such a system won't let you down.
