Embedded technology of embedded Internet is another milestone in the history of the development. It is based on the development of Internet technology, embedded technology. Embedded Internet technology is a combination of embedded technology and Internet technology, with embedded Internet technology to enable access to the Internet embedded device with remote monitoring, diagnosis, and management functions. Embedded system, in particular the most widely used8-bit,16bit,32-bit microprocessors for embedded systems access to the Internet has become the representative of the current hot research.Dissolved oxygen content is an important indicator of water quality monitoring. At present, there had been initially achieved in dissolved oxygen monitoring dissolved oxygen detection equipment to inject real-time detection in water, but most of the dissolved oxygen monitoring systems subject to regional restrictions still remain in a small, even on a single point, static monitoring mode. Large area such as the Yangtze River, the waters of Chaohu Lake, and dissolved oxygen concentration detection with dispersion, dynamic characteristics, the use of traditional methods of testing cannot be comprehensive, effective detection.This article is based on embedded Internet technology to study by distribution in large-area content of dissolved oxygen in waters of more than one monitoring device access to the Internet so as to build a large-area water points, dynamic monitoring system for dissolved oxygen content.The main content of research and achievement in this paper can be abstract as followings:1.Research on intelligent embedded Ethernet conversion module (MCU module built-in TCP/IP Protocol) with a corresponding external conversion circuit and associated network configuration, thereby directly embedded dissolved oxygen monitoring devices access to the Internet.2.Research on more than one control network of PC machine and monitoring network of multiple monitoring devices for network topology framework. By analyzing more dissolved oxygen detection equipment, wireless sensor devices and characteristics of distribution and connection of multiple PC machines, reasonable structure of the whole monitoring network topology.3. Research, development and completion ports based on multithreading technology of dissolved oxygen in waters of large-area monitoring system software. In Visual C++ platform environment, using multithread technology and complete port technology to develop a dissolved oxygen monitoring system software based on c/s mode, dissolved oxygen detection point applies to the large number of occasions, and you may still be able to maintain higher communication system stability.This research achievements in this paper for further upgrade dissolved oxygen detection level especially large area waters of dissolved oxygen detection level, and development new of water pollution monitoring technology lay solid of theory Foundation and Technology Foundation, is modern information technology in dissolved oxygen monitoring research area once mechanism sexual and Foundation sexual of exploration, has important of theory and practice significance, and for "property networking" of construction laid theory and application Foundation. |
