1. The basic design principle of user-centered
In the design process of the system, the designer should grasp the characteristics of the user and discover the user's needs. In the whole development process of the system, it is necessary to continuously solicit the opinions of users and consult with users. The design decision of the system should 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 the development, so that the developers can correctly understand the needs and goals of the users, and the system will be more successful.
2. The principle of order
That is, according to the order of processing events, the order of access and viewing (such as from the whole to the single item, from large to small, from the upper to the lower, etc.) and the control process flow and other design monitoring management and man-machine dialogue main interface and its secondary interface.
3. Functional principle
That is, according to the specific use function requirements of the object application environment and the occasion, various subsystem control types, the same interface parallel processing requirements of different management objects and the simultaneity requirements of multiple dialogue interactions, etc., the human-computer interaction interface such as the window that distinguishes multi-level menus, hierarchical prompt information and multiple dialogue bars simultaneously is designed by sub-functions, so that users can easily distinguish and grasp the use law and characteristics of the interactive interface, and improve its friendliness and ease of operation.
4. The principle of consistency
Including the consistency of color, the consistency of the operation area, and the consistency of the text. That is, on the one hand, the interface color, shape, and font are consistent with national, international, or industry standards. On the other hand, the interface color, shape, and font are self-contained, and the colors of different devices and their same design state should be consistent. The consistency of the interface detail art design makes the operator feel comfortable looking at the interface without distracting him. For new operators, or those dealing with problems in an emergency, consistency also reduces operator errors.
5. Frequency principle
That is, according to the frequency of dialogue interaction of the management object, the hierarchical order of the human-machine interface and the display position of the dialog window are designed to improve the frequency of monitoring and accessing dialogue.
6. The principle of materiality
That is, according to the importance and global level of management object in the control system, the position and prominence of the primary and secondary menus and dialogue windows of the man-machine interface are designed, so as to help the management personnel grasp the priority of the control system, implement the sequence of control decisions, and realize the optimal scheduling and management.
7. Object-oriented principle
That is, according to the identity characteristics of the operator and the nature of the work, the human-machine interface that is suitable and friendly is designed. According to the needs of their work, it is advisable to display prompts, guidance and help information in pop-up windows, so as to improve the user's interaction level and efficiency.
Human-computer interaction interface, whether it is for the field controller or for the upper monitoring and management, the two are closely intrinsically related, and the field equipment objects of their monitoring and management are the same, so many field device parameters are shared and passed to each other between them. The standardized design of human-machine interface should be the future development direction, because it does embody the principle of easy vision, simplicity and practicality, and fully expresses the human-oriented design concept. A variety of industrial control configuration software and programming tools provide a powerful means of support for the production of exquisite human-computer interaction interface, and the larger and more complex the system, the more it can reflect its superiority.

Buke servo motor - AC servo motor vibration fault analysis
Mechanical
1. Bearing
The bearing clearance on the lead screw housing is too large after wear, or the bearing roller elements and cages are severely worn due to the lack of grease in the bearing, resulting in excessive loads. After bearing wear, the clearance is too large, which will cause the coaxiality error between the center of the motor rotor and the center of the lead screw.
