Description
Technical field
The present invention relates to the implementation method that multi-screen interactive represents, especially relate to the implementation method that a kind of multi-screen interactive of XML-based file represents.
Background technology
In today of informationization rapid growth, the demand of information visualization enlarges rapidly, high-end visual realization difficulty is also more and more higher, the information that the separate unit display device can show can not be met the need of market far away, the needs of the important places such as some Surveillance center, command centre, control centre particularly, double screen interaction or multi-screen interactive have become the indispensable core technology of information visualization.The method that solves at present double screen or multi-screen interactive mainly concentrates on hardware devices such as using multihead display card or split screen card, the multihead display card can make many display screens of a computer supported, show different separately pictures at different screens, several display screens can form the large picture of a width of cloth again jointly, mouse can be roamed arbitrarily between a plurality of screens, also can be with any application, extend to and take two even more screen by taking a screen; The split screen card then cuts into the identical content blocks of size dimension with the displaying contents of computer export, is presented at respectively on the corresponding display device.But no matter be by multihead display card or split screen card, all be difficult to set up the mutual control relation between the application program, reach the operation interaction effect between the application program, also be difficult to realize on the display screen of any amount, arbitrarily representing.
Summary of the invention
Technical problem to be solved by this invention, the implementation method that represents with regard to the multi-screen interactive that provides a kind of XML-based file, the application of adopting the Flex technology to set up, access at different display devices respectively by the Internet, co-operate XML file set up control relation, use Asynchronous Invoke Technology to reach page part and refresh, and then realize multi-screen interactive.
The technical solution adopted for the present invention to solve the technical problems is as follows:
The implementation method that a kind of multi-screen interactive of XML-based file represents may further comprise the steps:
S1 sets up internet environment and software runtime environment, comprises a station server S, two client M1, M2:
S2 sets up an XML file X in server S, X file record control flag bit, and content is 0 or 1, and it is 0 that the initial marking position is set, and detailed content is as follows:
S3 configures Java Runtime Environment in server S;
S4 uses Java technological development java applet, comprises two functions: write function write () and read function read (), function is read operation and the write operation to control flag bit among the XML file X; After the debugging test is correct, java applet is compiled as Class file C;
S5 is at server S deploy Class file C;
S6 uses the BlazeDS technology, sets up the java application and the communication port that operates in the Flex application program on the browser on backstage;
S7 sets up rich client by the Flex technology and uses A1, and A1 realizes pressing the XML file function on the fixed interval cyclic access server;
S8 uses A1 with rich client and is deployed in the server S;
S9 is on display device M1, and by inputting URL(uniform resource locator) to server request A1 application service at browser, server acknowledge also provides service, and the content of pages of the upper displaying of M1 A1 is the column tendency chart;
S10 uses A1 and carries out the XML file function of pressing on the fixed interval cyclic access server, and judges state of a control;
S11 sets up rich client by the Flex technology and uses A2, the A2 interface comprises two button B1 and B2, the clicking operation of B1 and B2 can be called by the trigger event of Flex the write () function of Class file C, realize respectively the write operation to control flag bit among the XML file X, be that B1 will control flag bit and be written as 0, B2 and will control flag bit and be written as 1;
S12 uses A2 with rich client and is deployed in the server S;
S13 is on display device M2, and by inputting URL(uniform resource locator) to server request A2 application service at browser, server acknowledge also provides service, and the content of pages of the upper displaying of M2 A2 is two control buttons;
S14 clicks button B2 on the A2 interface, and execution in step S11 namely calls the write () function of Class file C, will control flag and be written as 1, and the content of file X is:
S15 is according to the function setting of A1 in step S7, and server returns control signal new among the XML to A1, and within 1 second time, the local content at A1 interface is changed to pie accounting figure by the column tendency chart;
S16 is according to step S7 and step S11, in like manner, can set up the function by A1 control A2, reaches A1 and A2 controls mutually, realizes that double screen is interactive, effect is refreshed in the part.
Described step S1 comprises:
The S1-1 server S is installed web server software, and Web service is provided;
S1-2 client M1, M2 install browser software and Flash Player plug-in unit;
The S1-3 server and client side is by the Http protocol communication, and client is obtained Web service by URL(uniform resource locator) access S;
The S1-4 client can be the polytype display devices such as LCDs, touch screen and mobile device; Described step S7 comprises:
S7-1 triggers the read () function that the Flex event is called Class file C, realizes the read operation to control flag bit among the XML file X.When the control flag that reads is 0, column tendency chart of the showing interface of A1, when the control flag that reads was 1, a pie accounting of the showing interface figure of A1 realized that the part of the page is refreshed;
S7-2 calls the Time assembly of Flex, starts timing function, every N time second (now being set as 1 second), execution in step S7-1;
S7-3 repeats above process, and the content of A1 showing interface and the control flag bit in the XML file are consistent.
Beneficial effect: the present invention can realize the interactive operation control of a plurality of display screens, has the following advantages and good effect:
1. XML-based file storage control signal does not rely on the hardware devices such as multihead display card or split screen card, and realization is simple, and it is convenient to dispose, and is quick on the draw, and it is strong that interaction is felt, but the relation of the control between the Set arbitrarily display device;
2. can realize that based on the Asynchronous Invoke Technology of Flex the part of the page refreshes, promote the user and experience;
3. be easy to expand to the polytype display devices such as LCDs, touch screen, movable screen.
