为增加网管控制中心 14对屏蔽系统的控制, 可以在初级网管, 以及各 级网管中设立子数据库服务器 141、 142、 143 14η, 151、 152、 15η、 16η, 这些数据库服务器用于存储低一级分布式网管中心的数据,初级网管中心数 据库服务器存储各集中控制器 13连接的各个屏蔽器 111的运行数据。 在数 据库服务器中还可以设置数据恢复控制器,该数据恢复控制器用于在屏蔽器 重启时将存储的屏蔽器 111的最新状态数据通过集中控制器 13传送至屏蔽 器 111 , 以应付系统遭遇不正常电力中断时, 能够迅速将屏蔽系统调节至既 定的最佳工作状态。
图 5为本发明应用在监狱的网络化屏蔽管理的实施例。例如,全国有 900 座监狱, 这些监狱通过初级屏蔽控制单元与市、 省级网管中心通讯, 地市级 网络中心分别受省级和全国屏蔽网络中心控制, 而分布在不同地理位置的多 级屏蔽控制单元通过互联网承载, 实现全国的通讯、管理、状态报告与报表。 在该实施例中各级网管按照权限分级管理, 网管控制中心可以对下辖的各级 网管及屏蔽器进行监控, 并随时根据需要对屏蔽器的工作状态进行灵活调 整, 不仅做到大面积区域的无缝屏蔽, 而且可以实现不同地理位置的分级管 理。
图 7是本发明本发明另一种无缝屏蔽系统实施方式的示意图,表示一种 移动构建方式的无缝屏蔽系统。 如长途运输车辆, 为了防止司机在驾驶车辆 时使用移动手机通话酿成车祸灾难。 其具体技术方案如下:
将屏蔽器 111安装到车辆驾驶员座位下侧, 屏蔽器 111的屏蔽范围只限 于驾驶员的区域。 同时屏蔽器的信号接收端包含有一个为车载 GPS 无线接 收发送模块 16, 屏蔽器 111通过 GPS信号传输与远程端运输公司设立的集 中控制交换器 13和网管控制中心 14进行通信。 屏蔽器 111的工作状态, 参 数等通过 GPS无线接收发送模块 16将数据发送到网管控制中心 14, 网管控 制中心 14的指令,屏蔽器 111参数的设置等也是通过集中控制器 15的 GPS 无线接收发送模块 17传输到屏蔽器端, 从而对屏蔽器 111进行监控, 网管 控制中心 14与车载的屏蔽器 111的数据通过远程无线通道透明传输。 屏蔽 器所有的工作状态网管中心都可以进行监控和调节, 以便于最及时了解车辆 安全状况。
本发明再一种无缝屏蔽系统实施方式, 为临时组建构建方式的无缝屏蔽 系统。
在很多场所需要临时建立屏蔽系统,针对屏蔽区域中的无线通信信号进 行屏蔽, 例如考场, 临时会议室等。 首先按照屏蔽区域按照无缝屏蔽合理的 布置屏蔽器的安装位置。根据屏蔽区域内的数据传输网络资源选择最合适的 数据传输网络, 如以太网, 光纤网络, 无线传输网络, 电力线等。 将屏蔽器 接入到屏蔽区内的网络后同时接通电源。 屏蔽器开机初始化以后, 根据连接 的网络资源, 请求将屏蔽器链接到初级网管控制系统中。 集中控制器连入到 与屏蔽器相连的网络中, 同时链接到初级网管控制中心, 初级网管控制中心 通过运行相应的软件程序,根据检测到的屏蔽器请求编号接入到监控系统中 建立连接,此时初级网管控制系统即可对临时屏蔽系统中的所有屏蔽器进行 监控, 管理和维护。

本发明能够针对目前无线通信领域内的 CDMA、 PCS, DCS, PCS, PHS、 GSM、 SCDMA, TD-SCDMA、 WIMAX和 WCDMA等无线通信信号 进行屏蔽, 屏蔽信号的频率范围包括 800 MHz ~ 900 MHz、 1800 MHz ~ 1900 MHz以及 3G、 4G通讯制式, 同时用户可以根据实际需要通过集中控制器方 便地选择需要屏蔽的无线通信信号频段, 以及屏蔽运营系统升级。
