| Along with the progress and extendedness of technology, theintegration degree of the whole production system in many enterpriseshas become higher and higher, more and more digitization informationprocessing is requested. At present the national isotope level,especially used in chemical, cement and electric power domain, hassame common mistakes, mostly complex electric circuit, troubledebugging, low measuring accuracy, low sensitivity, low intelligence,simple functions and unable operation in LAN control network.This text has designed a kind of level which can be used inindustry LAN environment, and carried out a collective scheme onhardware and software about it. Aimed at the requirement ofdistributed detect-control, it analyzed and designed informationexchange and its integration, adopted distributing objectprogramming in data transmit and data transact, used .Net Remotingtechnology between detect port and inspect system to realizeeffective call remote object, used XML format to exchange data. Allthese made the instrument more opening and more integrative.Adopting the visual instrument technology in network environment,the article has come true the online detect-control isotope levelsystem based on the industry computer. This research result can beused to detect and control on online in most important fields, inparticular especially hot, high-pressured, causticity and poisonousenvironment or equipments. It may help the enterprise to realize theproduction information integration, the long-distance control andthe production automation. |
