摘要
为了解决有线电视入户收费难的问题,采用可寻址集线器为核心器件,构成了有线电视可寻址收费控制管理系统,达到了有线电视收费现代化管理的目的,单片机是集线器的关键控制器件,实现了对用户信号端口的远动开关功能,并得到了广泛的推广应用,对集线器结构和软硬件设计方案进行了介绍,可为设计类似系统提供参考和借鉴。
Because it is difficult to collect CATV toll, so the pay TV management control system is made. The addressable hub controlled by a single chip computer is the key part in the system, It has the function of switching the TV signal on/off, and it has been used widely in many cities, The structure and soft-hard ware design scheme in the addressable hub is introduced, which is a reference for design in future,
