The Research And The Realization Of Networked Instrument Based On Embedded System

The networked instrument is a new trend of measuring technology and instrument development. It is the application in the field of observation and control technology and instrument and apparatus. With the technology, such as computer, microelectronics, sensor, communication, network, etc. It breaks through traditional communication the space-time restriction and region obstacles of ways, it is for instrument long-range to operate and network experiment platform, realizing that offered the ground floor to support.However, these new-type instruments also have a lot of questions, embodied in: The traditional structure of instrument can't already satisfy the function in control accurately, task realizing, communication protocol, networked, etc; The developer has consumed a large amount of time in order to be familiar with the embedded systematic structure, which has lengthened construction cycle; The portability of the software is bad, the utilization ratio of secondary development is low.To these questions, this text analyses in depth the characteristic of the embedded system, has combine the characteristic of the measuring instrument, and put forward a kind of standard structure based on networked instrument of the embedded system. Research work is the realization and launching around the networked instrument. First of all, this text has described that measures evolution of technology and instrument and its wide application, the networked instrument is its present development trend. Secondly, after the characteristic of the instrument, the text has put forward four layers of structure of the networked instrument, and deeply introduced each layer of construct and character. In addition, it has set up a software and hardware platform according to four layers of structure of the networked instrument, and realizes networked SF6 gas detector, providing the programming instance and the performance of analysis. Finally, it reviews and summarizes to go on to work what the text do, looks forward to networked development trend of instrument.
