Under this kind of demand, China moves the GPRS service to throw the person operation promptly, the wireless data communication's application is getting more and more widespread. Relatively original GSM digit dialing way's circuit switching data transfer way ... -
Realizes based on the GPRS J2ME movement platform under embedded Linux_linux, GPRS, KVM, J2ME
Tuesday, December 1st, 2009 at 16:21 | No commentsCategories: Embedded systemShort Content: Along with the mobile termination equipment's vigorous development, in the market presented all kinds of hardware equipment and the software platform. How to cause the service the designer is independent from the network operator in order to design may step the platform application procedure, puts in the service provider it (or equipment producer) in the network, thus may supply each kind of mobile termination user downloading and the installment, at present this pattern has become one kind of ... -
Based on the STC monolithic integrated circuit and GPRS chart article LED screen
Tuesday, May 26th, 2009 at 18:39 | No commentsCategories: SCMShort Content: 1 preface GPRS (General Packet Radio Service, general grouping wireless service) the appearance has used the existing GSM network fully, is not only suitable for interrupted, burst characteristics or frequent, the few data transmission, is also suitable for the occasional great data quantity transmission. It causes the mobile communication and the data net combines, it uses "the packet switching" (Packet Switch) the concept develops a set of wireless transmission mode, but uses the existing radio-frequency spectrum highly effective, is the ... -
Uses the monolithic integrated circuit to realize GPRS to correspond the small system’s research
Friday, December 5th, 2008 at 12:09 | No commentsCategories: Communication NetworksShort Content: 0 introductions GPRS (groups wireless activity is a use package of exchange concept development set of wireless transmission mode general). The GPRS network is (whole world mobile communication system) the network realizes based on existing GSM. Needs to increase some nodes in the existing GSM network, like GGSN (GPRS gateway support node) and SGSN (GPRS service support node). The SGSN leading role is records the mobile termination the current positional information, and completes the migration integrated data between the ... -
Based on GPRS mailing address street light monitor’s design
Wednesday, November 19th, 2008 at 00:45 | No commentsCategories: Communication NetworksShort Content: Abstract: This article described one kind based on the GPRS mailing address street light monitor design. Key word: GPRS; Street light monitoring IntroductionLive the enhancement which along with the urban night scene illumination facility's rapid development and the people savors, set a higher request regarding the urban light facility construction. The road lighting street light, decorated the colored lantern, the light eruptive fountain, the colored lantern lawn, the building spotlight and so on various characteristic light to constitute the beautiful ... -

Transmits the terminal design based on AT91R40008 embedded GPRS
Thursday, October 30th, 2008 at 12:57 | No commentsCategories: Communication NetworksShort Content: Abstract: This article gave one kind to connect Internet in view of the industry main line's embedded system the wireless surfer plan, discussed has realized the subject matter which in this plan must solve. Designed and has realized transmits the terminal based on at91R40008 microprocessor and G18 GSM module embedded GPRS, used the hierarchical structure and the standard interface, has realized based on real-time operating system µ C/OS-ⅡThe embedded TCP/IP agreement stack, has carried on the analysis to software system's ... -
Based on GPRS SOCKET correspondence applied research
Friday, October 17th, 2008 at 17:47 | No commentsCategories: Communication NetworksShort Content: Abstract: The SOCKET correspondence is one of present commonly used mailing addresss. In the article takes the micro controller by 8 monolithic integrated circuit AT89C52, it uses bringing the asynchronous serial port and level switch chip MAX232 and the GPRS module connection, uses at order to carry on the control for GPRS module LT8030, thus realizes the SOCKET correspondence. Introduces at order which in detail in the SOCKET correspondence must use, and gives realizes the SOCKET correspondence complete routine. Key ... -
Based on a LPC2124 remote system software promotion plan
Friday, September 26th, 2008 at 14:56 | No commentsCategories: SCMShort Content: The abstract in view of intelligent terminal's system software long-distance promotion and the maintenance difficult question, proposed that one kind the design proposal which promotes based on the LPC2124 remote system software. Introduced that LPC2124 the main performance and the characteristic, on the piece the Flash constitution and ISP, IAP and JTAG and so on many kinds of programming method's principle of work, and elaborated systematically long-distance IAP in uses electricity in the scene monitor terminal application. Finally discussion to ... -
Lives at the controller design based on the ARM intelligence with to realize - en.51rd.net
Tuesday, September 23rd, 2008 at 00:37 | No commentsCategories: SCMShort Content: Abstract: How family in a relatively independent device attachment system, thus facilitates carries on this locality and the remote control? This article through uses the ARM constitution intelligence to live at the controller to achieve this goal. The intelligence lives at the controller to use parts and so on S3C2410, SIM100-E to compose the hardware platform, transplants again the Linux system to the hardware platform, then designs the good corresponding driver and the application procedure, finally downloads the software to the ...
