With realizes - en.51rd.net based on the LIN main line’s headlight online diagnosis system design
Wednesday, May 27th, 2009 at 03:59 | No commentsCategories: SCMShort Content: 1 introduction The automobile bussing technique is one of field bus's applications, the initial field bus only uses in the industrial control. The so-called field bus is the application in the production lowest level one kind always the linear analysis situs network. The automobile body directed net needs to solve at present the question is establishes a unification, the low cost low end communication network standard, LIN exists as the CAN auxiliary main line, realizes the automobile body directed net ... -
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 ... -
Profibus-DP scene rest line correspondence master station design

In the numerous field bus product, open style field bus Profibus which was ... -
Based on RS-485 field bus’s network air-conditioning system - 51RD Chinese electronic net
Tuesday, October 28th, 2008 at 18:43 | No commentsCategories: Communication NetworksShort Content: 1st, introduction Since the 1990s, along with information technology's rapidly expand, specially interconnecting network technology's making great strides, the information more and more universal penetration in our daily life, it quietly has been changing our life style, the information electrical appliances also from this arises at the historic moment. As the traditional electrical appliances' air-conditioner to intellectualized, digitized, the network direction evolution, realizes the comprehensive digitization, is precisely ultimately. With the aid of the interconnecting network, the telephone network ... -
Based on AT89C51CC01 monolithic integrated circuit’s CAN-LIN gateway design
Wednesday, October 22nd, 2008 at 00:25 | No commentsCategories: Communication NetworksShort Content: Introduction Field bus technology already widespread application in industrial control, particularly CAN (Controler Area Nerwork) main line, because has the reliability to be high, the cost low, easy to realize and so on merits, held the big share in field bus's actual project application. Follows the bussing technique development, LIN (Local Interconnect Network) the main line is taking one kind of low cost the serial communication network, its goal is provides the auxiliary function for the existing field bus ...
