Emerson installs wireless system at Milford Power
 
艾默生为Milford电厂安装无线系统

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.

奥斯汀9月26日消息——艾默生过程管理成功地应用其无线自组织现场网络监测Milford电厂运营的远程系统和设备建筑。Milford电厂是位于康涅狄格Milford市的一个500兆瓦的燃气涡轮机电厂。艾默生的智能无线解决方案使得这家电力公司节省了多达7万5千美元的资金和安装成本，同时改善保护水泵和循环设备免受冰冻损害，节省可多达2万美元的维修或者更换成本。

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.

尽管远程基站在寒冷天气期间还是热的，但Milford电厂的管理层希望有一种方法可以不断地告知电厂的操作人员在一旦严重降温的情况下加热器发生故障，可以采取快速纠正行动。由于直接安装配线之间的远程监控设备和监控室已经十分昂贵，所以Milford电厂的官员开始寻找一个可靠的无线通信系统，以一个合理的成本满足他们的需求。

"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电厂维护主管Cliff Esmiol这样评论：“我们考察了许多技术，并选择了艾默生无线解决方案和Rosemount无线温度变送器，因为我们喜欢这样的通信方式，以及电池寿命和成本。尤其重要的是这个易用、灵活的自组织网络可以在很短的时间里安装和使用。”

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.

艾默生无线解决方案通过放置在全电厂内的十二个水泵的设备来调试。这个网状网络仅需两个小时就可以通信。信号很容易在建筑物和其他障碍物周围发送，在Milford电厂提供了这样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.

经过初步评审之后，兴建了另一座大楼，完全封住了一个变送器免受网络上其他变送器的影响。这没有任何区别，无线网络的信号没有受到影响。

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.

来自远程设备的数据通过一个1420网关连接到控制室的一个现有PC里，而控制室里现有的互联网浏览器用来显示测量和在一旦显著降温的情况下发出报警。

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.

艾默生的智能无线解决方案是PlantWeb数字工厂架构的一个扩展，结合了高度可靠的智能监测设备和无线变送器，以及一项时间同步网状协议（TSMP) 通信技术。这一创新的自组织网状网络，可以随着设备点的添加和移除而自动适应，已经在现实环境里经过了广泛的测试。

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."

维护主管Cliff Esmiol表示：“毫无疑问，这是一个很好的无线解决方案，行之有效，易于安装，很容易根据需要进行扩展。”
