7 Guidelines for Designing Industrial Touch Screens

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 indicator lights. It can be used to set parameters, display data, monitor the status of equipment, and describe the automated control process in the form of curves/animations. Compared with general touch screens, industrial touch screens have the advantages of fireproof, waterproof, anti-static, anti-pollution, anti-grease, anti-scratch, anti-flicker, and high light transmittance. 

 

The design of industrial touch screens should follow the following 7 basic principles:

 

1. The Basic Principle of User-centered

 

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 solicited continuously. 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. Sequence Principle

 

The designer should clarify the sequence of event processing, the sequence of visits and viewing (such as from the whole to the single item, from large to small, from upper to lower, etc.) and the control of the process flow. On this basis, design the main interface of monitoring management and human-machine dialogue and its secondary interface.

 

3. Functional Principle


That is to design according to the specific use function requirements of the target application environment and occasions, various subsystem control types, etc. The designed human-computer interaction interface should include multi-level menus, hierarchical prompt messages and multiple dialog boxes simultaneously, so that users can easily distinguish and grasp the rules and characteristics of the interactive interface. The friendliness and ease of operation of the equipment will therefore be improved.

 

4. The Principle of Consistency

 

Consistency principles include the same color, the same operating area, and the same text. On the one hand, interface colors, shapes, and fonts 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 who deal with problems in emergency situations, consistency can also reduce their operational errors.

 

5. The Principle of Frequency

 

That is to design the hierarchical sequence of the human-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. The Principle of Importance


The location and prominence of the interface's primary and secondary menus and dialog windows help managers to grasp the primary and secondary control systems, implement the control decision sequence, and achieve optimal scheduling and management.

 

7. Object-oriented Principle

 

The designer designs a suitable and friendly human-machine interface according to the operator's identity characteristics and work nature. According to their work needs, prompts, guidance and help information should be displayed in pop-up windows to improve the level and efficiency of user interaction.

 

Industrial touch screens are closely related to each other, whether it is for on-site controllers or for upper-level monitoring and management. The standardized design of the touch screen should be the future development direction, because it really embodies the basic principles of easy-to-understand, simple and practical, and fully expresses the people-oriented design concept. Various industrial control configuration software and programming tools provide powerful support means for making exquisite touch interface. The larger and more complex the system, the more it can reflect its superiority.

Identify Different Types of Transformer Cores, Based on Materials

  Hi guys, this is JRPanel ! In previous  blog s, we have introduced several points about High Frequency Transformer, like  bobbins  and  Flat Spiral Coil . In this blog, JRPanel would like to introduce the commonly used magnetic cores in transformers ,  based on materials.   Generally speaking, the material of the core determines the environment in which the transformer is used. A transformer that uses a core of a different material will have its performance affected, may even be non-functional.   By material, magnetic cores are generally divided into the  several  categories . JRPanel will introduce them one by one to help you understand more fully.   1. Manganese Zinc Ferrite Core Mn-Zn core is a soft magnetic core with high initial permeability (2000~15000). The higher the initial permeability, the lower the surface resistance, so it is generally used in circuits below 1 MHz. Mn-Zn core has a high saturation flux density and causes lower losses, making it one of the most desirable

The Relationship Between Plastic Nameplates and Membrane Switches

Before the 1970s, most nameplates   were made of metal materials. Today, plastic  nameplates   have been widely used in household appliances, instruments, meters, office equipment and other fields, and have become an indispensable part of electromechanical products. It not only plays the role of trademark identification, specification model, function indication, etc., but also becomes an element that reflects the appearance of the product.   With the continuous use of new materials and new processes, the surface of plastic  nameplates   is constantly improving, and it has become the crystallization of three major technologies: comprehensive surface treatment, processing and molding, and screen printing.   Plastic  nameplates   can be divided into 2 types according to their material processing methods and objects of use:   1. The injection-type plastic  nameplate   is made of ABS, PC and other engineering injection molding, and then undergoes secondary surface decoration processing such

The Main Use and Classification Methods of Transformer Bobbins

  Hi guys, this blog is still about   high frequency transformers .   JRPanel   would like to introduce you the main use of transformer bobbins and how we classify them.   In the pictures are the transformer bobbins.        Following are the main uses of that JRPanel has summarized for you:   1. The bobbins provide space for winding copper wires in transformers.   2. Wire channel in the bobbins provides path for transformer winding.   3. The bobbins help to fix the core in the transformers.   4. The metal pins in the bobbins are connected to the  PCB  after soldering, which play an important role in conducting electricity when the transformer is working.   5. The baffle at the bottom of the bobbins isolates the core from the tin stack to avoid poor volta ge resistance.       From this it can be seen that the importance of bobbins in transformer is extraordinary.   After understanding the main uses of transformer bobbins,  JRPanel  is to introduce its common classification methods.   Fi
