传感器自适应遥测终端在中小型水库中的应用

Application of Auto-adaptive RTU at Medium and Small Scale Reservoirs

目前市场上,大多数水情遥测终端机只能适应专用的传感器和通讯机,本文设计的传感器自适应遥测终端有效地解决了该问题。简要分析遥测站设备具有自适应调解功能的必要性,详细描述终端机如何对水情传感器的波特率、传输协议等参数进行自动判断和识别,从而使得遥测设备具有简单的,无须人工干预的智能化调解的功能。该设备通过948项目应用证明其安全、方便、可靠。

Presently, most remote terminal units（RTU） can only connect to special sensors and communicationcontroller. An auto-adaptive RTU is developed to resolve the problem. The article makes a concise analysis on necessities that remote station equipment should possess function of auto-adaptive, elaborates the RTU how to make automatic estimation and identification to parameters of baud rate and transmission protocols of water regime sensors, thus the RTU has convenient and smart regulation function without manual intervention. The RTU has already been applied in 948 items, and its application proves the security, convenience and reliability of the unit.
