金飞鷃(Kingfisher)遥测遥控遥信系统(以下简称遥测系统),是美国爱克新公司的CIM-PAC2000分布式控制系统中一个子系统。对分布式控制系统而言,通信始终是系统中的一个重要组成部分,国内外绝大多数分布式控制系统(含分散型控制系统)都采用局域网(LAN)进行通信,该种方式可靠性高,通信速率快,缺点是通信距离有限,一般在几百米到几千米之间,通过中继放大虽然可以扩展通信距离,但对于那种地域分布广阔(超过几十公里),测量控制点很多的对象,仅用LAN实现通信联系就显得相当复杂且价格昂贵。CIM-PMC2000分布式控制系统的通信则除了传统的局域网外,还增加了金飞鷃遥测系统,可以通过专用线、公共电话线或无线电进行通信,并且正在开发一种小型微波发送、接收组件,完成后可以实
Kingfisher telemetry remote telecontrol system (hereinafter referred to telemetry system) is a subsystem of CIM-PAC2000 distributed control system of American Agape. For distributed control systems, communication is always an important part of the system. Most distributed control systems (including decentralized control systems) at home and abroad adopt the local area network (LAN) for communication. This method has the advantages of high reliability , Communication speed, the shortcoming is the communication distance is limited, generally between a few hundred meters to several kilometers, though the relay amplification can extend the communication distance, but for that kind of geographical distribution (more than tens of kilometers), measurement control point A lot of objects, only the LAN to achieve communication links can become quite complex and expensive. In addition to the traditional LAN, the CIM-PMC2000 Distributed Control System also adds a Gold Telemetry telemetry system that can communicate via dedicated lines, public telephone lines or radios and is developing a small microwave transmitting and receiving assembly, After the fact can be done
