Human-computer interface (also known as user interface or user interface) is the medium of interaction and information exchange between the system and the user, which realizes the transformation between the internal form of information and the form acceptable to humans. Human-machine interfaces exist in all areas involved in the exchange of information between humans and machines.
The human-machine interface product is composed of two parts: hardware and software, the hardware part includes the processor, the display unit, the input unit, the communication interface, the data storage unit, etc., in which the performance of the processor determines the performance of the HMI product, which is the core unit of HMI. Depending on the product level of the HMI, the processor can be 8-bit, 16-bit, and 32-bit processors. HMI software is generally divided into two parts, namely the system software running in the HMI hardware and the screen configuration software running under the PC Windows operating system (such as JB - HMI screen configuration software). Users must first use the HMI's screen configuration software to create "engineering files", and then download the compiled "engineering files" to the HMI's processor through the serial communication port between the PC and the HMI product.
The basic functions of the human-machine interface product and the basic functions of the selection index: Display of the working status of the equipment, such as indicator lights, buttons, text, graphics, curves, etc. Data and text input operation, printout Production recipe storage, equipment production data recording Simple logical and numerical operations Can be connected to a variety of industrial control equipment networking Selection Indicators: Display size, color, resolution Processor speed performance of HMI Input method: touch screen or membrane keypad screen storage capacity, Pay attention to whether the capacity unit indicated by the manufacturer is byte or bit, the type and number of communication ports, and whether the printing function is supported.
Human-machine interface product classification The HMI with membrane key input has a display size of less than 5.7', and the screen configuration software is free, which is a primary product. Such as POP - HMI small human-machine interface touch screen input HMI, the display size is 5.7'-12.1', the screen configuration software is free, it is an intermediate product Based on the tablet PC computer, a variety of communication ports, high-performance HMI, the display size is greater than 10.4', the screen configuration software is charged, it is an excellent product.
How to use the HMI Clarify the requirements of the monitoring task and select the appropriate HMI product Editing the "Project File" with the Screen Configuration Software on the PC Test and save the edited "Project File" The PC is connected to the HMI hardware and the "Project File" is downloaded to the HMI Connect the HMI to the industrial controller (such as PLC, instrument, etc.) to achieve human-computer interaction.
