Connect industrial control devices such as programmable logic controller (PLC), inverter, DC governor, instrument, etc., use the display screen to display working parameters or input operation commands through input units (such as touch screen, keyboard, mouse, etc.). A digital device that realizes the interaction between human and machine information, consisting of hardware and software. HMI is the abbreviation of English Human-Machine Interface.

A digital device that realizes the interaction between human and machine information, consisting of hardware and software. HMI is the abbreviation of English Human-Machine Interface.
Product composition and working principle
The human-machine interface product consists of hardware and software. The hardware part includes the processor, display unit, input unit, communication interface, data storage unit, etc. The performance of the processor determines the performance of the HMI product and is the core of the HMI. unit. Depending on the product class of the HMI, the processor can use 8-bit, 16-bit, 32-bit processors, respectively. The HMI software is generally divided into two parts, namely, the system software running in the HMI hardware and the screen configuration software (such as the JB-HMI screen configuration software) running under the Windows operating system of the PC. Users must first use HMI's screen configuration software to create "project files", and then download the compiled "project files" to the HMI processor through the serial communication port of the PC and HMI products.
Basic functions and selection indicators
basic skills:
Device working status display, such as indicators, buttons, text, graphics, curves, etc.;
Data, text input operation, printout;
Production recipe storage, equipment production data record;
Simple logic and numerical operations;
Can be connected to a variety of industrial control equipment networking.
Selection indicator:
Display size and color, resolution;
HMI processor speed performance;
Input method: touch screen or membrane keyboard;
Screen storage capacity, note that the unit of capacity indicated by the manufacturer is byte (byte) or bit (bit);
Whether the type and number of communication ports support printing.
Product classification Thin film key input HMI, display size is less than 5.7 ËŠ, screen configuration software is free, is a primary product. Such as POP-HMI small human machine interface;
The HMI of the touch screen input, the display size is 5.7ËŠ~12.1ËŠ, the screen configuration software is free, and it is a mid-level product;
Based on the tablet PC computer, a variety of communication ports, high-performance HMI, display size is greater than 10.4 ËŠ, screen configuration software charges, is a high-end product.
2. After the projector is connected to the mobile phone through the Bluetooth function, the projector acts as a speaker and can play music from the mobile phone.
