This paper presents the development of an intelligent grain moisture content measuring system based on SCM 8031. By adopting technologies of artificial neural network (ANN), virtual instrument (VI) and others, the system achieves digitization of the total moisture content measuring process (distributed measuring and centralized data processing) with characteristics of high precision and stability,...
Base on analysis of influence factor about strip's convexity degree and transverse thickness, established online monitoring system of cold rolling strip's thickness and convexity degree, to emulate by application of LabVIEW software, and compare with the practical situation, as result of it could mainly meet requirement of online virtual monitoring.
In the food processing industry, getting rid of cracked eggs is an important process. At present in China, the method of detecting damaged eggs is mainly by hand, by which detection workers observe eggs under the light or turning eggs to bump into each other so as to listen to the voice of the eggshell. Thus, the method is labour intensity, but also the low efficiency and poor precision. In this paper,...
As an emerging family entertainment centre, DVD recorder is able to play home videos and record TV shows into built-in hard disk or RAM disc. Its quality plays an essential role in its market share around the world for manufacturers. Consequently, as the most important part of the DVD recorder, the motherboard is needed to be checked and measured thoroughly in the manufacturing process of DVD recorders...
H2S is a kind of poisonous gas that exist in oil, chemical production process. The detection of H2S plays an important role in mine, oil and gas exploration, production of chemical product, control of atmosphere environment. The monitoring system for The H2S gas volume fraction has been designed in the application of virtual instrument technique and special H2S sensor of gas sensitive thin film invented...
This paper discusses the researching process of simulating dynamic weighting signal in the aspect of signal on MATLAB, based on the conception and researching method of virtual instrument. The signal simulation includes parts of the production line, the mechanism of balance (a Second-Order Underdamped System), response of object, response of the mechanism and power frequency noise. This paper analyzes...
