Description

一种基于航拍的小区动态巡逻的通讯中继系统 技术领域
本发明涉及安防领域，尤其是基于航拍的小区动态巡逻的通讯中继系统。
背景技术
为了防止盗窃等不良事件的发生，各小区物业公司均聘请保安对小区进行巡逻，夏天太阳下太热、冬天夜间太冷，都可能发生保安并未真正按时巡逻的现象。这时可使用基于航拍的小区动态巡逻系统，并利用WIFI实现实时通讯。但当小区规模较大时，目前的小区动态巡逻系统无法实现全方位的通讯，如何实现有效通讯将成为亟需解决的问题。
发明内容
本发明所要解决的技术问题是提供一种基于航拍的小区动态巡逻的通讯中继系统，监控方位更广，而且能够有效通讯。
为解决上述技术问题，本发明的技术方案是：基于航拍的小区动态巡逻的通讯中继系统，其特征在于：包括巡逻无人机、监控中心、多个一级通讯中继和多好二级通讯中继，每一个一级通讯中继与一个以上的二级通讯中继连接，所述巡逻无人机通过wifi与一级通讯中继和二级通讯中继通讯；一级通讯中继与监控中心连接；所述巡逻问人机包括无人机自动导航模块、GPS定位模块、处理器及其接口控制电路、广角低照度摄像头、夜视补光灯和WIFI发送/接收模块；
一级通讯中继或二级通讯中继都将定时往监控中心发送心跳报文，以证实通讯顺畅，其中二级中继需通过一级中继转发至监控中心；
巡逻无人机采用广播发送WIFI数据，凡是能接收到巡逻无人机 发送出来的图像数据的通讯中继都向监控中心报告，并提供信号强度；
监控中心根据各通讯中继发送的报告数据及各通讯中继收到的信号强弱作出是否需要从一个通讯中继切换至另一通讯中继来收取图像数据；在切换的前后小段时间内，如果是前后两个通讯中继没有公用的通讯通道，则收取这两个通讯中继的数据，然后由监控中心来选择查看哪一路数据；如果是两个通讯中继存在公用的通道，为了不增加通道通信量，由监控中心向发送停止某个通讯中继然后开启另一个通讯中继传送图像数据的命令。
本发明与现有技术相比所带来的有益效果是：
本发明通过采用分层实现基于航拍的小区动态巡逻的通讯中继系统，在保证通讯通道传输的数据量不超标的情况下最大限度地接收巡逻无人机传输回来的图像数据。
附图说明
图1为本发明系统框图。
图2为巡逻无人机结构框图。
具体实施方式
下面结合说明书附图对本发明作进一步说明。
如图1所示，基于航拍的小区动态巡逻的通讯中继系统，包括巡逻无人机、监控中心1、多个一级通讯中继2、3和多好二级通讯中继4、5、6。每一个一级通讯中继与一个以上的二级通讯中继连接，所述巡逻无人机通过wifi与一级通讯中继和二级通讯中继通讯，一级通讯中继与监控中心1连接。如图2所示，所述巡逻问人机包括无人机自动导航模块、GPS定位模块、处理器及其接口控制电路、广角低照度摄像头、夜视补光灯和WIFI发送/接收模块。
本发明的通讯中继系统分层次实现，包括监控中心1、一级通讯中继 和二级通讯中继。各个通信通讯中继按WIFI辐射的有效距离，均匀安排在小区的相关位置，尽量处于无遮挡位置。一级通讯中继或二级通讯中继都将定时往监控中心1发送心跳报文，以证实通讯顺畅，其中二级中继需通过一级中继转发至监控中心1。巡逻无人机采用广播发送WIFI数据，凡是能接收到巡逻无人机发送出来的图像数据的通讯中继都向监控中心1报告，并提供信号强度。监控中心1根据各通讯中继发送的报告数据及各中继收到的信号强弱作出是否需要从一个通讯中继切换至另一通讯中继来收取图像数据。在切换的前后小段时间内，如果是前后两个通讯中继没有公用的通讯通道，如一级通讯中继2和一级通讯中继3，则收取这两个通讯中继的数据，然后由监控中心1来选择查看哪一路数据；如果是两个通讯中继存在公用的通道，如一级通讯中继2和二级通讯中继4或者二级通讯中继4和二级通讯中继5，此时为了不增加通道通信量，由监控中心1向发送停止某个中继然后开启另一个中继传送图像数据的命令。如当巡逻无人机7从一级通讯中继2飞向一级通讯中继3时，则收取这两个通讯中继的数据，然后由监控中心1来选择查看哪一路数据；当巡逻无人机7从二级通讯中继4飞向二级通讯中继5时，此时为了不增加通道通信量，由监控中心1向发送向二级通讯中继4发送停止其传输图像数据功能，然后向二级通讯中继5发送开启传输图像数据功能。
