摘要
在地铁数字电视发展过程中,对其信号覆盖网络系统进行监测是地铁现代化、信息化的一个重要组成部分。为及时准确地监测和定位系统内的设备,提出了两种解决方案:基于GPRS网络小区的定位和基于2.4 GHz无线数据传输技术的定位。介绍了上海地铁数字电视信号覆盖系统,讨论了方案的系统总体框架、硬件设计和软件架构,并对这两种方案进行了比较。
During the development of metro DTV, the monitoring for its coverage is an important part of modern metro informational system. Two effective methods for monitoring and locating the abnormal system equipment accurately are presented in this paper, which is separately based on GPRS cell location and 2.4 GHz wireless data transceiver technique. After the simple introduction of DTV system in Shanghai Metro, the system structure, hardware design and software architecture are discussed mainly,and the two kinds of strategies are compared.
