The Development Situation And The Virtualization Countermeasure Of Environment Supervision Instruments

Environment supervision is an important meaSure on managemem of environment,the core instrument,viz.environment supervision instrument plays an important role in thewholeprocess. The VI(virtual instrument)is a new type of testing instrument developed in the twenty eighty'S,which is based on the microelectronics technology,computer technology,soRware technology and electron measure technology.It has powerful function and is also easy to operate and expand.VI soon becomes the trend of testing instrument.In this paper,an environment supervision instrument combining with VI technology researched.This kind of environment instrument represents the development trend ofthe environment instrument. In this paper,the basic conception and development situation are introduced firstly, which leads to the necessity trend of virtualization of environment supervision instrument.Secondly,the conception,the features,the produce and situation,the constitution and the bmlding process of a virtual instrument are introduced.After analyzing the principal and the structure of all kinds of environment supervision instrument,this paper gives a detailed description on the development situation,and also gives the virtualization countermeasure.Namely,develop domestic analysis software that has OUr own knowledge property;develop virtual physics supervision instrument,this section begun from vibration,noise,electromagnetism radiation,then investigate the virtual instrument.According to the sound analysis,an assumption of a virtual sound intensity analyzer is put forward and its control panel is also given; develop domestic network virtual instrument in the field of automatic environment supervision.In the same time,the paper expounds the virtue of virtual environment supervision instrument,indicating that the virtual environment supervision instrument represents the development direction of the environment supervision field.it has excellent quality,multi-function,and integration,automation,sytemafism, intelligentize.It satisfied the demand offuture environment supervision instrument.
