The industrial touch screen is an intelligent interface that connects people and machines through a touch-type industrial display. It is an intelligent operation display terminal that replaces traditional control buttons and indicators. It can be used to set parameters, display data, monitor device status, and depict automated control processes in the form of curves/animations. Compared with the general touch screen, the industrial touch screen has the advantages of fireproof, waterproof, anti-static, anti-pollution, anti-grease, anti-scratch, anti-flicker and high transmittance. The design of industrial touch screens should follow the following seven basic principles:

1. User-centered basic design principles

In the design process of the system, the designer must grasp the characteristics of the user and discover the needs of the user. In the entire development process of the system, we must constantly seek the opinions of users and consult with users. The design decisions of the system 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 to do this is to involve real users in development so that developers can understand the user’s needs and goals correctly and the system will be more successful.

2, the principle of order

That is, according to the sequence of processing events, access viewing order (such as from the whole to the single item, from large to small, from the upper layer to the lower layer, etc.) and the control process flow, etc., the design monitoring management and man-machine dialogue main interface and its secondary interface are designed.

3, the principle of function

That is, according to the specific application requirements of the target application environment and occasions, various subsystem control types, parallel processing requirements of the same interface of different management objects, and simultaneous requirements of multiple dialogue interactions, etc., design sub-functions to distinguish multi-level menus, hierarchical prompts The human-computer interaction interface such as the information and the multiple dialog columns, so that the user can easily distinguish and grasp the usage rules and characteristics of the interactive interface, and improve the friendliness and ease of operation.

4, the principle of consistency

Consistent color consistency, consistent operating area, and consistent text. That is, on the one hand, the interface color, shape, and font are consistent with national, international, or industry common standards. On the other hand, the interface color, shape, and font are self-contained, and the colors of different devices and their identical design states should be consistent. The consistency of the interface details and the aesthetic design makes the operator feel comfortable when looking at the interface, thus not distracting him. For new operators, or operators who deal with problems in an emergency, consistency can also reduce their operational errors.

5, frequency principle

That is to say, according to the frequency of the interactive interaction frequency of the management object, the hierarchical order of the human-machine interface and the display position of the dialog window, and the display position of the dialog window are improved, and the frequency of monitoring and accessing the dialogue is improved.

6, the principle of importance

That is, according to the importance and global level of the management object in the control system, the position and the highlight of the main menu and the dialogue window of the man-machine interface are designed, thereby helping the management personnel to grasp the master and the control system and implement the control. The order of decisions to achieve optimal scheduling and management.

7, object-oriented principles

That is, according to the identity characteristics of the operators and the nature of the work, design a human-machine interface that is compatible and friendly. According to the needs of its work, it is advisable to display prompts, guidance and help information in a pop-up window to improve the level of user interaction and efficiency.

Industrial touch screens, whether for field controllers or for upper-level monitoring and management, are closely related to each other. The objects they monitor and manage are the same, so many field device parameters are shared and mutual between them. Passed. The standardized design of the touch screen should be the future development direction, because it does reflect the easy-to-follow, simple and practical basic principles, and fully expresses the people-oriented design concept. Various industrial control configuration software and programming tools provide powerful support for the beautiful touch interface. The larger the system, the more complex it is.
