介绍两种典型的有线电视网不间断电源（UPS）的远程监控系统的实现方案，设计实现了一种基于单向CATV网络UPS的远程监控通信系统，这种监控系统利用公用电话网（PSTN）传输UPS信息，这样通过监控中心计算机可实现对整个CATV网络中UPS的网络化管理，从而提高网络供电质量，确保CATV信号传输的可靠性。
This paper introduces the realization of two typical remote monitoring systems of uninterruptible power supply (UPS) in cable television network, and designs and implements a remote monitoring and control communication system based on unidirectional CATV network UPS. This monitoring system utilizes public telephone network (PSTN) Transmission UPS information, so through the monitoring center of the computer network can be achieved throughout the CATV network UPS management, thereby enhancing the power quality of the network to ensure the reliability of CATV signal transmission.
