Research and application of key technologies for B/S man-machine interface

摘要

A B/S (browser/server) human-machine interface architecture of separate front-end and back-end is proposed. The micro-services architecture is used to develop the services in the service layer. The standardized service publishing/discovery mechanism, uniform format for message data encapsulation and message subscription theme are implemented to support multiple applications. A new CIM/G graphics conversion method is illustrated which can convert CIM/G graphics to SVG graphics and provide more information for better graphics display. The real-time data push method based on WebSocket is designed to realize pushing multiple graphics data with single WebSocket connection. The B/S human-machine interface has been running stably for more than half a year, compared with the traditional human-machine interface, it can display graphics data in a faster and more efficient way to fulfil requirements of application data display.
