摘　　要：利用HFC网络实现区域监警的功能:在一个小区内利用HFC网进行双向数据传输,设置报警中心,在用户端安装报警终端,并给出了系统的组成、工作原理、硬件结构及软件实现。当发生警情时,报警终端机可将用户安装地址信息、警情、运行状态上传至接警控制中心主机,也可执行接警控制中心主机发出的指令(如布防、撤防、状态查询等)。A regional alarm and monitor system is realized through CATV-network. Two-way data transmission is performed through the network and an alarm center is set up within a small region, and an alarm terminal is installed at the subscriber end. The system composition, operating principle, software and hardware are given. When alarm-case occurs, the alarm terminal transmits a signal to the alarm center, which includes address information, alarm situation, operating status of the alarm terminal and so on. Likewise, the alarm terminal can execute commands received from the alarm center, such as set-up alarm, shut-up alarm and status polling.
