Embedded network intelligent control system’s research
Monday, December 8th, 2008 at 22:22 | No commentsCategories: Communication NetworksShort Content: Abstract: The embedded equipment and the Internet union will be representing the embedded technical true future. In the article the embedded network intelligent control system unifies the embedded operating system and the Internet network, first has given based on the Web server's embedded network intelligent control system's architecture; Then, has designed the software system, and has given between the embedded network intelligent control terminal and the Web server the exchange of information message format, proposed dispatches server's parameter computational method ... -
Realizes - 51rd based on the AVR ATmega128 industry gateway the Chinese electronic net
Monday, November 24th, 2008 at 17:39 | No commentsCategories: SCMShort Content: Abstract: Introduces one kind of bridge joint different field bus network the solution. This plan uses high performance AVR ATmega128 is its control core. AVR ATmega128 uses the ModBus/RTU agreement and the computer correspondence, controls the equipment correspondence through the multi-processor correspondence pattern with other minutes. This plan passes through moves in reality, proved that its design is feasible. Key word: AVR ATmega128, Modbus/RTU, AVR multi-processor correspondence pattern, CRC16 1 introduction Now, the electronic technology development is ... -
Based on network multichannel ultra width video frequency system’s research
Wednesday, November 19th, 2008 at 22:59 | No commentsCategories: Communication NetworksShort Content: Introduction In recent years along with the digital compression technology, the computer and the networking was unceasingly mature and the development, the people had more demands to the video frequency and the network. Present's digital video demonstration picture is too generally small, is unable to suit the numerous audience's onlookings, but the multichannel ultra width video frequency system is one kind from the real-time cutting output, the network synchronization broadcast demonstration the synchronization broadcasts the multimedia documents during different PC ... -
How to use the new differentiator processing separate time domain signal
Tuesday, November 18th, 2008 at 15:52 | No commentsCategories: Communication NetworksTags: differentiator, networkShort Content: This article introduced uses in calculating the separate time domain (digit) the sequence derivative highly effective computing network. This article described one simply in view of the recursion derivative network, and may guarantee that linear phase the minute meets the delay line (limited impact on respond, or calls FIR) the differentiator. In the continuous signal domain, the differential definition is clear, but is not true in the separate territory. However, is good in us may the ... -
Based on DVB/MPEG-2 satellite Internet technical
Monday, November 17th, 2008 at 04:19 | No commentsCategories: Communication NetworksShort Content: The Internet application's rapid promotion, caused him to fall into the difficult position which one overcame with difficulty. This is because Internet is one "between the net the net", he is by many IP autonomous territory system through the interconnection constitution compound network system. The transmission band width increases, the exchange rate enhancement as well as the traffic engineering introduction, fundamentally in the change transmit message process has not jumped, the memory repeater and the point-to-point transmission working pattern, ... -
Based on telephone line system long-distance promotion plan
Tuesday, October 21st, 2008 at 22:12 | No commentsCategories: Communication NetworksShort Content: Along with internal FLASH ROM in the MCU domain's widespread application, ISP (In-system programmable) the component development is widespread, but profits from this technology, the massive monolithic integrated circuit system under the normal work voltage, can realize the software update procedure storage space, thus carries on the promotion function to the system. The intelligent measuring appliance should amount used increase as well as the technical progress, causes the people to seek for the operators not to be able unceasingly ... -
Based on DSP optical fiber data acquisition network development
Wednesday, September 24th, 2008 at 00:03 | No commentsCategories: DSPShort Content: 1. Introduction The neutrality ties pours into the acceleration power source is a set of high-pressured high efficiency pulse power source which extremely fusion test installation (EAST) develops for national greatly scientific project superconductivity Tocker the Mark. This power source uses Pulse Step the Modulation[1] technology, becomes (Figure with 80 same 1100v/100A output's power source module series 1), its specified output is: 80kv/80A, maximum pulse width 1000s. Because this power source puts in high-pressured, under the strong electromagnetic interference ...
