无线局域网在EMS中的应用探讨

A STUDY OF WLAN IN EMS

本文论述了ＬＡＮ应用于ＥＭＳ时存在的一般性问题，探讨了无线局域网应用到ＥＭＳ中的一种途径，并讨论了在实时性和可靠性要求上无线局域网具有的一些优势。

High requests are needed in EMS(Energy Management Systems).Such as real-time ability,high reliability,etc. And this system should be extended or maintained easily.If Using special line to communicate, such abilities as high speed connection, low transferring delay and large capacity can be aquired. But the great deal of investments,maintaince can’t be accepted. EMS based on LAN(Local Area Networks)has been established in China ,but it is not perfect for EMS. This paper suggests an approach that applying WLAN(Wirless Local Area Networks)in EMS,the protocol is also modified.
