Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail：
As shown in figure 1, the structural representation of the subway multimedia education system provided for the present invention, including teacher computer andMember's machine；Wherein, the teacher computer and student's machine are mounted on aided education module, equipment simulating module, examination test mouldBlock and system setup module；The teacher computer is also equipped with student's machine management module.Each functional module is discussed in detail below：
(1) aided education module
Aided education module, for being imparted knowledge to students in the form of playing curriculum video；The content of instructional video covers urban railIntroduction, power supply mode introduction, primary equipment introduction, second protection introduction etc..
Specifically, curriculums table is shown using tree-like hierarchical form, when some video text in the curriculums table of the bottomWhen part is clicked, that is, play corresponding video；Also, set in broadcast window and play console, the broadcasting console includes：Playing progress bar, start button, pause button, fast backward button, fast forward button, volume knob.
(2) equipment simulating module
Equipment simulating module, for the exercise of PSCADA simulated operations, by this part of study, exercise, can allowMember has the understanding of a complete display to the operating with of power transformation PSCADA systems, fault treating procedure.
For the main interface of equipment simulating module, point top, left side, right side, the region of bottom four can be to aforementioned four areasDomain carries out arranged below：
(a) top include current location, cabinet selection (3 voltage class), the selection of online mode and exercise mode,Event information view, real-time curve, navigate this several.
(b) left side for simulation figure selecting, i.e., station selection.It can hide, the navigation after hiding at the top of click can be shownOut.
(c) right side homepage, is first entered into as welcome page, have selected left side station after for the station view.
(d) bottom is main menu.For showing main functional modules corresponding with role.
Equipment simulating module core functional module includes：Isochronous controller, main wiring diagram simulated operation unit and emulation cabinetBody simulated operation unit；And/or also include cabinet simulated operation unit in kind；
If configured with cabinet simulated operation unit in kind, then：Main wiring diagram simulated operation unit, cabinet simulation behaviour in kindThe state for making unit and emulation cabinet simulated operation unit synchronizes change；
