本技术涉及工业自动化采集控制设备,尤其是组成工业监测控制系统(SCADA系统)的主要设备—远程测控终端RTU。远程测控终端RTU在工业监测控制系统SCADA中起者重要的作用,采集、控制、通讯功能是它的基本功能。由于远程测控终端RTU经常工作在野外,因此用户对它的性能有很高的要求。目前,国内国外厂商生产的远程测控终端RTU主要分为两大类组合型和固定型。组合型远程测控终端RTU是通过模块组合集成而成的,模块种类一般有主控模块、I/O信号输入输出模块、电源模块、通讯模块等。这种类型的远程测控终端RTU没有固定的形式,一般是用户提出功能要求,由系统集成商选择模块、选择结构形式集成而成。模块可以是自产的,也可以从专业的模块生产厂家购买。这种类型的远程测控终端RTU具有灵活多变的特点,可以根据用户不同的要求进行不同的组合。但也正因为如此,它很难形成固定的模式,很难具有固定的产品型号,为用户的选型、应用带来了麻烦。另外这类远程测控终端RTU的应用涉及到多方面的因素,如用户的因素、系统集成商的因素、模块生产厂家的因素,所以产品质量不易控制。固定型远程测控终端RTU是使用固定电路封装而成的,电路一般包括主控电路、I/O信号输入输出接口电路、通讯接口电路等。目前市场上大多这类远程测控终端RTU产品不具备电源电路和通讯电路。此类型的远程测控终端RTU产品具有固定的I/O信号输入输出接口数量,具有固定的产品型号,体积小、重量轻,使用起来比较方便。但由于它们的I/O信号输入输出接口固定,因此适应面比较窄,应用领域有限,一般应用于专用场合。另外此类产品由于缺少电源和通讯部分,因 ...
