This plan through used ARM DSP main from the structure, embedded LINUX systematic and the reasonable task allocation strategy has guaranteed system's timely request, and network data transfer rate demand control in feasible scope. Discussed Ethernet to apply in the industry test diagnosis system's related key technologies question. Along with the computer ... -
Based on TMS320F2812 fast ethernet communications system platform
Monday, August 31st, 2009 at 23:50 | No commentsCategories: DSPShort Content: Introduction Along with Internet application day-by-day popularization, information sharing degree unceasing enhancement. The embedded equipment's digitization and the network already became the inevitable trend, at present in the market mainstream embedded operating system has contained the TCP/IP network protocol stack. These commercialization's TCP/IP agreement stack movement is reliable, the performance is also good, but the price is high, reduced the market competitiveness. Therefore, the development proprietary intellectual property rights's TCP/IP agreement stack's request changes is day by day urgent and ... -
Has the ethernet connection accumulator cell to turn into supervisory system’s design
Tuesday, May 26th, 2009 at 16:52 | No commentsCategories: SCMShort Content: 1 introduction The battery plate comes of age the skill is in the accumulator cell production process important link. So-called turns into has referred to the pole plate charging and discharging process, namely using the electrochemistry responded that causes the electrical energy to transform the chemical energy to store up. The accumulator cell turns into the charging and discharging process is under the external voltage the complex chemical reaction process, needs the supervisory system antipode plate current voltage value to ... -
High power ethernet power supply no longer difficult
Tuesday, May 5th, 2009 at 20:07 | No commentsCategories: Power SupplyShort Content: The high power ethernet power supply (HPOE) the standard still has not determined until now. The most people expected the standard is: The power line voltage increases to 53VDC, each line available electric current to achieve 750mA, the electric cable total impedance not to surpass 12.5 ohms. If some people expected that designs 46VDC (nominal 48V) the voltage, the 720mA electric current, the electric cable impedance is 12.5 ohms, perhaps that will be the worst situation. Because in 720mA time, ... -
Power source management chip in ethernet power supply application
Saturday, May 2nd, 2009 at 07:07 | No commentsCategories: Power SupplyShort Content: What is the ethernet power supply?The terminology "the ethernet" is refers to IEEE802.3 standard covering each kind of local area network (LAN) system. The ethernet agreement is in the operational site, through the high speed data electric cable the agreement which connects table model PC and the central file server. Any connects the ethernet port's equipment, like the data terminal, the wireless junction point, the network camera (web cam) either the network telephone and so on, needs through the battery ... -
With realizes - en.51rd.net based on the TPS2384 PSE design
Tuesday, February 24th, 2009 at 13:54 | No commentsCategories: Power SupplyShort Content: Introduction Ethernet Chinese Journal of Power Sources standard IEEE 802.3af to network equipments and so on router, switchboard and concentrator through the ethernet electric cable to equipment and so on IP telephone, safety system as well as WLAN junction point provided power source's way to carry on the stipulation. The Texas Instruments company has promoted power source management chip TPS2383 and TPS2384 successively, their compatible 802.3af standard, may provide the direct-current power supply through a standard ether mesh ... -
Based on SEP3203 embedded ethernet mouth design
Thursday, December 11th, 2008 at 19:16 | No commentsCategories: Communication NetworksShort Content: The abstract in the automated control and other civil equipment, domains and so on industrial control like power equipment system, the numerous equipment's foreign communication connections was still the low speed serial port. But the low speed serial port has its inherent shortcoming: Is unable to concentrate, comprehensive, accurate and real-time monitors the data. This article introduced that based on the microprocessor SEP3203 serial port ethernet switch's ethernet connection's software and hardware design method, it may change traditional the serial ... -
Gains the more electric power from the ethernet power supply
Wednesday, December 10th, 2008 at 23:16 | No commentsCategories: Communication NetworksShort Content: Introduction< ?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> The ethernet supplied power (PoE) already to become a very popular concept, and in many products was obtaining the widespread use, for example: The network telephone, monitors the camera as well as the sale point terminal safely. The ethernet power supply is allocates and dispatches the electric power through an ethernet connection. In provides the ethernet power supply in the network, the electric power is provides by power equipment (PSE), ... -
In the CAN main line interconnection gateway’s design with realizes - en.51rd.net
Wednesday, December 10th, 2008 at 03:16 | No commentsCategories: Communication NetworksShort Content: Abstract: This article has studied the CAN main line and the ethernet interconnection technical point systematically, first analyzes the interconnection technique to realize the difficulty - - protocol conversion which in the process meets. Then proposed one kind of CAN main line and the ethernet system interconnection design proposal, and elaborated in detail its system's software and hardware realizes the method. In order to enhance system's performance, uses high speed micro controller SX52 to design the embedded transparent gateway, introduced ... -
