Emerson installs wireless system at Milford Power
 
艾默生為Milford電廠安裝無線系統

AUSTIN, TEXAS - September 26, 2007 - Emerson Process Management successfully applied its wireless self-organizing field network to monitor remote system and equipment buildings operated by Milford Power, a 500 MW gas-fired turbine facility in Milford, Connecticut. Emerson's Smart Wireless Solution enabled the power company to avoid as much as $75,000 in capital and installation costs while advancing the protection of water pumping and circulation equipment against freeze damage that could cost as much as $20,000 to repair or replace.

奧斯汀9月26日消息——艾默生過程管理成功地應用其無線自組織現場網絡監測Milford電廠運營的遠程系統和設備建筑。Milford電廠是位于康涅狄格Milford市的一個500兆瓦的燃氣渦輪機電廠。艾默生的智能無線解決方案使得這家電力公司節省了多達7萬5千美元的資金和安裝成本，同時改善保護水泵和循環設備免受冰凍損害，節省可多達2萬美元的維修或者更換成本。

Although the remote stations are heated during cold weather, executives of Milford Power wanted a way to continuously inform plant operators of severe temperature drops in case of a heater failure so that fast corrective action could be taken. Since installing direct wiring between remote monitoring devices and the control room would have been very expensive, officials at Milford Power began looking for a reliable wireless system to satisfy their needs at a reasonable cost.

盡管遠程基站在寒冷天氣期間還是熱的，但Milford電廠的管理層希望有一種方法可以不斷地告知電廠的操作人員在一旦嚴重降溫的情況下加熱器發生故障，可以采取快速糾正行動。由于直接安裝配線之間的遠程監控設備和監控室已經十分昂貴，所以Milford電廠的官員開始尋找一個可靠的無線通信系統，以一個合理的成本滿足他們的需求。

"We looked at various technologies and selected the Emerson wireless solutions with Rosemount wireless temperature transmitters because we liked the communications approach, plus battery life, and cost," commented Cliff Esmiol, maintenance supervisor for Milford Power. "Especially important was the easy, flexible self-organizing network that could be installed and operational in a very short time."

Milford電廠維護主管Cliff Esmiol這樣評論：“我們考察了許多技術，并選擇了艾默生無線解決方案和Rosemount無線溫度變送器，因為我們喜歡這樣的通信方式，以及電池壽命和成本。尤其重要的是這個易用、靈活的自組織網絡可以在很短的時間里安裝和使用。”

The Emerson wireless solution was commissioned by placing twelve devices at pump locations around the power plant. The mesh network was communicating in only two hours. The signals were easily transmitted around buildings and other obstructions, proving the capability and reliability of this concept at Milford Power.

艾默生無線解決方案通過放置在全電廠內的十二個水泵的設備來調試。這個網狀網絡僅需兩個小時就可以通信。信號很容易在建筑物和其他障礙物周圍發送，在Milford電廠提供了這樣概念的能力和可靠性。

After the initial evaluation was completed, another building was constructed that completely blocked one transmitter from others on the network. It didn't make any difference; the wireless network signals were unaffected.

經過初步評審之后，興建了另一座大樓，完全封住了一個變送器免受網絡上其他變送器的影響。這沒有任何區別，無線網絡的信號沒有受到影響。

Data from the remote devices passes through a 1420 gateway connected to an existing PC in the control room, where the existing Internet browser is used to display measurements and sound an alarm in case of a significant temperature drop.

來自遠程設備的數據通過一個1420網關連接到控制室的一個現有PC里，而控制室里現有的互聯網瀏覽器用來顯示測量和在一旦顯著降溫的情況下發出報警。

Emerson's Smart Wireless solution is an extension of the PlantWeb digital plant architecture, combining highly reliable, smart monitoring devices with wireless transmitters and a Time Synchronized Mesh Protocol (TSMP) communications technology. This innovative self-organizing mesh network, which automatically adapts as device points are added or removed, has been extensively tested in real-world environments.

艾默生的智能無線解決方案是PlantWeb數字工廠架構的一個擴展，結合了高度可靠的智能監測設備和無線變送器，以及一項時間同步網狀協議（TSMP) 通信技術。這一創新的自組織網狀網絡，可以隨著設備點的添加和移除而自動適應，已經在現實環境里經過了廣泛的測試。

According to maintenance supervisor Cliff Esmiol, "Without question, this is an excellent wireless solution that works well, is easy to install, and very easy to expand if necessary."

維護主管Cliff Esmiol表示：“毫無疑問，這是一個很好的無線解決方案，行之有效，易于安裝，很容易根據需要進行擴展。”
