Abstract
The utility model relates to a device for dynamically displaying comparatively large external data at web pages without refurbishing. The device comprises a GPS vehicle terminal, a data base, a data extract and transformation server, a WEB server and a user terminal. The GPS vehicle terminal is communicated and connected with the data base by satellites, basic public communication networks and corresponding gateway technology; the data extract and transformation server is respectively connected with the data base and the WEB server; the WEB server is connected with the user terminal. Compared with the prior art, the utility model is characterized by being capable of dynamically displaying comparatively large data at web pages without refurbishing, high speed and high reliability, etc.
Description
Technical field
The utility model relates to Computer Applied Technology exploitation and communication technique field, and relating in particular to webpage does not dynamically have the device that refreshes the big external data of demonstration.
Background technology
Webpage shows that dynamically big external data is a WEB exploitation difficult point, and at present, the web data dynamic display device mainly is the attribute that utilizes HTML to carry, or directly utilizes the WEBSERVICES technology, and there is tangible drawback in these two kinds of devices.
Dynamically during video data the page refresh the page at set intervals, the page needs heavy duty.
2. when the page data amount is big, may cause the page to show.
3. can give the WEB server more for a long time when while accessed web page number and bring bigger pressure.
4. work as while accessed web page number and can bring bigger pressure to database more for a long time.
5. poor reliability goes wrong easily.
The utility model content
The purpose of this utility model is exactly to provide a kind of web displaying and travelling speed is fast, reliability is high webpage dynamically not to have to refresh the device that shows big external data in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
Webpage does not dynamically have the device that refreshes the big external data of demonstration, it is characterized in that, this device comprises GPS car-mounted terminal, database, data extract and change server, WEB server, user terminal, described GPS car-mounted terminal via satellite, basic public communication network and corresponding gateway technique be connected with database communication, described data extract and change server are connected with database, WEB server respectively, and described WEB server is connected with user terminal.
Described data extract and change server are with the data extract of the GPS terminal collection in the database and convert the corresponding uniform data source to.
Described uniform data source is XML (Extensible Markup Language, an extend markup language).
Described WEB server uses AJAX (Asynchronous JavaScript+XML) technology access uniform data source.
Compared with prior art, the utlity model has following characteristics:
1.WEB it is irrelevant that page or leaf shows with the employed database of system;
2. system can use various data sources;
3. solve the user concurrent problem and promptly can allow many users visit this webpage simultaneously, can not cause the pressure of WEB server to become big;
4. do not have when making the data of WEB page display data sources and refresh, can make the webpage travelling speed very fast relatively simultaneously;
5. the page is with respect to conventional apparatus, and dynamically the data presented quantitative change gets bigger.
Description of drawings
Fig. 1 is a system architecture synoptic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of webpage " does not dynamically have and refreshes " device that shows big external data, this device is used to solve the real time data demonstration problem that GPS terminal reports, it mainly comprises GPS terminal, the employed database of current system, data extract and change server, WEB server and user terminal, show problem in order to solve the real time data that GPS terminal reports, system also needs other system and technology (as satellite communication, public communication) to accept GPS terminal to gather vehicle-mounted current data and store in the database.The major technique of present embodiment is characterised in that: 1.WEB visits employed data source through being converted into the uniform data source; 2.WEB the page access data source has been used the AJAX technology; 3. convertible any one data source of data extract and change server; 4. database loads is less; 5.WEB server load is less.
The present embodiment device makes the WEB server directly not link up with database, has alleviated the pressure of database greatly, simultaneously, because adopted the AJAX technology, has so also alleviated the pressure of WEB server.
Claims (4)
1. webpage does not dynamically have the device that refreshes the big external data of demonstration, it is characterized in that, this device comprises GPS car-mounted terminal, database, data extract and change server, WEB server, user terminal, described GPS car-mounted terminal via satellite, basic public communication network and corresponding gateway technique be connected with database communication, described data extract and change server are connected with database, WEB server respectively, and described WEB server is connected with user terminal.
2. webpage according to claim 1 does not dynamically have and refreshes the device that shows big external data, it is characterized in that, described data extract and change server are with the data extract of the GPS terminal collection in the database and convert the corresponding uniform data source to.
3. webpage according to claim 2 does not dynamically have the device that refreshes the big external data of demonstration, it is characterized in that described uniform data source is XML (Extensible Markup Language, an extend markup language).
4. dynamically do not have the device that refreshes the big external data of demonstration according to claim 2 or 3 described webpages, it is characterized in that, described WEB server uses AJAX (Asynchronous JavaScript+XML) technology access uniform data source.
