针对公用事业的发展和数据可访问性的要求涉及大量的系统升级费用。一家位于德克萨斯州Austin的公用事业公司选用了无线以太网调制解调器,以扩展其原来的系统,消除数据采集的间隔。公用SCADA(监控和数据采集)系统的升级存在相当多的挑战。许多因素都会影响决策,尤其是费用。不仅仅包括更换的开支,而且还包括今后可伸缩性及将来会影响结果的不可预测的费用。Lakeway市政公用事业区坐落于Austin的西部,Travis湖上。它创建于1972年,管理社区10,000人的用水、废水和再用水。SCADA系统建立于1995年,包括一个本地操作员工作站和一个远程可编程
Requirements for the development of utilities and data accessibility involve a significant amount of system upgrade costs. A Austin, Texas-based utility company selected a wireless Ethernet modem to expand its legacy system to eliminate data collection intervals. There are considerable challenges in upgrading a common SCADA (monitoring and data acquisition) system. Many factors affect decision making, especially costs. It includes not only the costs of replacement, but also unpredictable costs of future scalability and future consequences. Lakeway Municipal Utilities is located west of Austin, on Lake Travis. Founded in 1972, it manages 10,000 people of water, wastewater and reuse water in the community. Founded in 1995, the SCADA system includes a local operator workstation and a remote programmable
