The industrial touch screen is an intelligent interface that connects people and machines through touch industrial displays. It is an intelligent operation display terminal that replaces the traditional control buttons and indicator lights. It can be used to set parameters, visualize data, monitor equipment conditions, and depict automation processes in the form of curves/animations. Compared with the general touch screen, the industrial touch screen has the advantages of fire prevention, waterproof, anti-static, anti-pollution, anti-grease, anti-scratch, anti-flicker, and high light transmittance. The planning of industrial touch screens should follow the following 7 fundamental guidelines:
1. User-centered fundamental planning criteria
In the planning process of the system, planners should grasp the characteristics of users and discover the needs of users. In the entire development process of the system, it is necessary to continuously solicit the opinions of users and consult with them. The planning and decision-making of the system should be combined with the user's working and operating environment, and it is necessary to understand the user's requirements for the system. The best way to do this is to involve real users in the development, so that the developers can correctly understand the needs and goals of the users, and the system will be more successful.
2. Sequence criteria
That is, in accordance with the order of processing events, the order of visit and inspection (such as from the whole to the single item, from large to small, from the upper level to the grassroots, etc.) and the control process and other planning, monitoring and man-machine dialogue main interface and its secondary interface.
3. Functional criteria
That is, according to the target application environment and the occasion of the detailed use of functional requirements, various subsystem control types, the same interface parallel processing requirements of different handling objectives and the same requirements of multiple dialogue interactions, etc., plan the human-computer interaction interface such as multi-level menus, hierarchical prompt information and multiple dialogue bars with equal emphasis on the window, and then the user is easy to distinguish and master the application rules and characteristics of the interactive interface, and improve its friendship and ease of operation.
4. Commonality criteria
Including the common color, the common operation area, and the common text. That is, on the one hand, the interface color, shape, and font are common to national, world, or professional standards. On the other hand, the interface color, shape, and font are self-contained, and the colors of different devices and their same planning conditions should be kept common. The commonality of interface detail art planning makes it comfortable for the operator to look at the interface and then not distract him. For new operators, or those dealing with problems in an emergency, commonality also reduces operator errors.
5. Frequency criterion
That is, according to the frequency of dialogue interaction of the management target, the hierarchical order of the human-machine interface and the display position of the dialogue window are planned, and the frequency of monitoring and visiting dialogue is improved.
6. Materiality criterion
That is, according to the importance and overall level of the management objective in the control system, plan the position and prominence of the primary and secondary menus and dialogue windows of the man-machine interface, and then help the handling personnel to grasp the priority of the control system, implement the order of control decision-making, and realize the optimal scheduling and handling.
7. Goal-oriented criteria
That is, according to the identity characteristics and work nature of the operator, the man-machine interface that is suitable and friendly is planned. According to the needs of their work, it is advisable to use pop-up windows to display prompts, guidance and help information, and then improve the user's interaction level and efficiency.
Industrial touch screen, whether it is for the field controller or for the upper level of monitoring and handling, the two are close to the internal connection, and the goals of their monitoring and handling of the field are the same, so many field equipment parameters are shared and transmitted to each other between them. The standardized planning of the touch screen should be the future development direction, because it does show the easy-to-dream, simple, practical foundation principle, fully express the people-oriented planning concept. A variety of industrial control configuration software and programming things provide a strong support for the production of exquisite touch interfaces, and the larger and more chaotic the system, the more it can show its superiority.
