Excellent hmi touch screen supplier
Human machine interface manufacturer and supplier 2023: Create the external model of the system function design model is mainly to consider the data structure, overall structure and process description of the software, interface design is generally only as an accessory, only the user’s situation (including age, gender, psychological situation, literacy, personality, ethnic background, etc.) have an understanding of the user to design an effective user interface; according to the end user’s hypothesis of the future system (referred to as the system hypothesis) The user model is designed to match the system image (external characteristics of the system) obtained after the system is implemented, so that the user can be satisfied with the system and can use it effectively; the information given by the system hypothesis should be fully considered when building the user model, and the system image must accurately reflect the syntactic and semantic information of the system. In short, only by understanding the user and the task can a good human-machine interface be designed. See additional info on hmi touch screen panel.
System Reliability Requirements: The reliability of the general system PLC can be met. For systems with high reliability requirements, consider whether to use redundant systems or hot standby systems. PLC should be unified possible. Mainly consider the following three aspects: The model is unified, and its modules can be used as backup for each other, which is convenient for the procurement and management of spare parts. The model is unified and its function and use method are similar, which is conducive to the training of technical forces and the improvement of technical level. The model is unified, its external equipment is universal, resources can be shared, easy to network communication, and it is easy to form a multi-level distributed control system after being equipped with a computer.
Interaction is a description of the relationship/status of human-machine-environment interaction. The interface is a concrete expression of the interaction between human and machine – environment. Interaction is the contextual portrayal to achieve information communication, and interface is the means to achieve interaction. In the interaction design subsystem, interaction is the content/soul, and interface is the form/body; however, in the larger product design system, both interaction and interface are only a means to solve the human-machine relationship, not the ultimate purpose, which is to solve and satisfy human needs.
It is good to choose a brand according to the needing of the customers or the market. But it is not for selecting a brand to decide, or more about to focus on its performance parameters, and to be used the functions achieved. Actually there is an attractive story behind the famous brand. So to choose a brand, try to achieve high practicality, to avoide waste one’s talent on a petty job. For example, Siemens, Mitsubishi, Proface, Panasonic brand…etc with a good performance, but before decision to select them, should consider, how many performance of HMI panel will be used for the project? Whether the cost paid matches the performance used on the project? Read additional details on mochuan-drives.com.
How To Solve Communication Failure Between HMI Operator Interface And PLC? When communication fails, some customers guess that it may be a problem with the touch screen all-in-one machine or the interface. Online simulation is to bypass the touch screen, use the PLC to connect directly to the computer, use our configuration software, connect the PLC’s own communication cable to the computer, conduct online simulation and see if the project can communicate.
Multi-touch capacitive hmi panel is new design and very popular with the market. Why? It is similar the Apple iPone in our life. Becuase its flexible multi touch, very high transmittance, Glass+Glass, anti-scratching, no drifting, IPS full view TFT lcd, high resolution, brightness, high speed and easy flow, supporting animation formats. The color of multitouch HMI is rich and the picture displayed is more delicate. Why many people follows iPhone, just becuase it can bring the users different and beyond imagination experience. Same reasons, why this type panel hmi is very popular in European and American market, just becuase it can bring the project, equipment different experience then to obtain more high value market and to be easily competitive the competitors. Maybe a little try, but to bring a large value, so why not try.
The regular China lcd human machine interface HMI touch screen is only to support 0°C to 50°C working envornment. HMI panel can not meet the application, the environment require the high or low temperature. It have to find the solution, such as to add one resistance or move the equipment in door or outdoor to make the temperature is suitabe its work needing. But face one question, it is not stable and very inconvenience. To solve this problem, to develop and design new type HMI touch panel, it is metal shell wide-temperature resistive HMI, supporting -20°C to 70°C. This type wide-temperature screen is very popular in Canada, Russia, United States…etc.
The Fourth Step: Communication Mode Preference is given to the HMI Panel itself with lower computer drive touch screen. Firstly, this is will be more convenient and simple in the definition of the subsequent project address and conversion, becuase if you choose Modbus compatible devices, it is necessary to convert the HMI touch screen monitoring address according to the rules of the definition of different lower computer(PLC) manufacturer, which not only greatly increase the workload of engineers and also easy to covert the wrong. Secondly, needing to draw up in advance, a communication program for the entire project. Do it need the ethernet to communicate with the upper computer, or need two rs485 to be maste or slave station communication, or through one rs485 and one rs232 communication to achieve.
Choosing the right industrial hmi touch screen panel and plc can not only adapt to the electrical room’s multi-interference operation environment, but also enable each cabinet to achieve intelligent operation management, intelligent maintenance safety, intelligent new energy generation, etc., in order to achieve the goal of enhancing the electrical room’s core competitive advantage and promoting the sustainable development of electricity.
The human-machine interface is the central link in the human-machine system, mainly by the safety engineering sub-discipline safety ergonomics to study and propose solutions based on the safety engineering equipment engineering, safety management engineering and safety systems engineering to study specific solutions and measures safety ergonomics. It realizes the conversion between the internal form of information and the acceptable form for human beings.
