現場總線(Field bus)是90年帶所興起的一種先進工業控制技術,它將當今網路通信與管理的觀念引入了工業控制領域。本質上,它是一種具有數位通訊協定,連接智能現場設備與自動化系統的數位式、全分散、雙向傳輸、多分支結構的通訊網路。 現場總線的代表是為美國Echelon公司所開發出的LonWorks技術,這種網路技術平台可達到『即插即用』以及『遠端監控』等理想,之外,LonWorks技術也具有互聯網的功能,讓不同規格的電氣設備也可以相互連結。 因此,本研究以LonWorks技術來開發智慧型遠端監控系統,發展出區域性校安聯防體系的基礎架構,結合其他研究想法來達成網路校際實驗室的監視系統、安全通報以及網路工安衛資料庫建置、更新以及即時監控。
The field bus (Field bus) is one advanced industry control technology which 90 years belt emerges, it now the network correspondence and the management idea has introduced the industry control domain. Essentially, it is one kind has several communications to reach an agreement, connection intelligence scene equipment and automated system several types, entire disperser, two-way transmission, multi- branched structure communication networks. The field bus representative is the LonWorks technology which develops for American Echelon Corporation, this kind of network technology platform may achieve "namely inserts namely uses" as well as "the far-end monitoring" and so on the ideal, beside, the LonWorks technology also has the Internet the function, enables the different specification the electrical equipment also to be allowed mutually to link. Therefore, this research develops the wisdom far-end supervisory system by the LonWorks technology, develops the regional school peaceful joint defense system foundation overhead construction, unifies other research ideas to achieve the network interscholastic laboratory the supervisory system, the safety message as well as the net road work peaceful health information bank establishes, the renewal as well as the immediate monitoring.
