Beijing DWIN Technology is a world-leading high-tech industrial automation enterprise which is dedicated to the research, development and manufacture of Human Machine Interfaces (HMI).
DWIN plays a major role in the market of Industrial UART display modules in the market of the construction machinery, healthcare instruments and electronic equipment with focus on high reliability. UART interface and simplified MCU and graphical programming make the applications easy.
HMI Modules with Touch
Many applications still using monochrom character or graphic display need to be upgraded to a color TFT display with a touch screen. However TFT display asks always for an efficient CPU platform supporting RGB or LVDS interface what usual low cost single chip microcontrollers can not offer. This means in many cases complete redesign of internal hardware and software. Next to more expensive microcontroller must be used, there is lot of development costs also, delay with product launching and all the potential risc with new product development.
However there is other much more simple solution available. Dwin's intelligent HMI modules with TFT display and touch screen can be connected by RS232/ RS485 or USB seriál interface to any application and easy to use GUI allows to finish the application in some few hours. Big advantage is that customers don't need to change main hardware or software of a current product and with a small time and cost investment can launch new product to the market really fast. The DWIN HMI modules are available as OEM version without housing or as a complete device with plastic or metal cover.
Special DGUS software (DWIN Graphical Utility Software) is a new GUI software which was developed in the way of configuration software via exchanging data between internal memory and reduce coding and programming for HMI development. Developing magnificient GUI with DGUS save 90% work of programing. With DGUS various functions, variable data input, popup window, slider, incremental adjustment, bit icons, timer display and others can be simply accomplish with touch screen.
The developing process is under way of a few steps. First step is planning of variables and definition of a read/ write area with available values. Second step is designing of graphic user interface like icons, pictures, fonts etc , for example in Adobe Photoshop. In third step using the DWIN software customer can setup all functions inclusive touchscreen functions. In next step configuration files and graphic design are uploaded via RS232/USB interface into the DWIN module and user can test, degug and revise complete application. In last step config files and images can be stored in SD card for filling and mass production.
DWIN OS runs on basis of DGUS firmware. It is a programming internal software in which database operations and user-defined algorithms are integrated for industrial automation. The software runs automatically at the background. DWIN modul can act as host in a RS485 network and manage other Modbus devices directly.
