-some LED driver modules send video data to pairing LED control card.
Embodiment two
The software general frame is to adopt B/S (browser/server) pattern.The computer programming that uses has: Java language (J2EE, STRUTS2 framework), html language, JavaScript language (ExtJS framework).
The mode of graphical interaction is adopted at the interface, foreground, and through click, drag-and-drop operation, the process that in software, gives operating personnel's a kind of " What You See Is What You Get " is experienced, and accomplishes the work of LED screen design conveniently, efficiently.The graphics context that software can design has: static text, dynamic text, picture file, simulated clock simulation clock, time on date, self-defined form, totally six kinds of objects.Can edit, manage a plurality of templates simultaneously.
The backstage service is to form through defining following three functional modules, solves the problem of data communication and LED coupling:
Definition LED screen control interface and realization class are responsible for LED hardware controls and Data Control; Definition LED parameterized template DTD and XML file, the data dictionary information that definition MES provides; Definition LED design document DTD and XML file, definition LED content element information;
The present invention can let a user-defined template, is applicable to multiple, polylith LED screen.
Thinking and process that User Interface is realized are following:
Foreground UI program is on Hypon MES software platform, to develop, and uses the JSP page program and realizes based on " the ExtJS framework " of JavaScript language.With sophisticated functions JavaScript program in the past different be; This software is realized the layering that interface content has carried out the MVC formula; Come elements such as package component, business, incident with OO thought; Use the notion of " closure " in the JavaScript technology in a large number, make that the whole software program structure is compact, interface is unified, code reusability is high.
The file of foreground UI program is formed structure:
The folder structure of UI part:
JS loads explanation: ()
User's operation example explanation of foreground UI program:
