一种输电线路的图像监测装置及方法 技术领域
本发明涉及输电线路在线监测领域,特别涉及一种输电线路监测方法及监测设备。
发明背景
为了能够进行电力的传输，在传输两端需要架设输电线路，输电线路分为架空输电线路和电缆电路等。为了保证电力的安全传输，就需要保证输电线路的安全性，所以需要实时监测输电线路是否处于正常的工作状态。采用输电线路的实时图像监测，就可以解决这个问题。
目前，对输电线路进行实时图像监测时采用输电线路图像监测装置，通常，该输电线路图像监测装置采用摄像机+无线通信模块的方式实现，具体可以采用摄像机+网络视频服务器(DVS，digital video server)实现，其中，摄像机与DVS之间通过Q9或BNC接口连接，用于实时对输电线路进行摄像，得到输电线路的实时图像，传输给DVS；DVS具有图像编码及无线传输作用，用于接收输电线路的实时图像并进行处理，如果通过该实时图像监测到输电线路存在异常，则通过网络发送报警信号。
但是，采用上述装置对输电线路进行图像监测存在以下缺点：
1)所述装置功耗比较大且体积重量较大，成本较高。所述装置中的DVS功耗一般在6瓦左右，而且无法进行休眠而降低功耗，所述装置中的摄像机功耗一般在10瓦左右，也没有低功耗，因此所述设备正常工作对供电电源的功率要求比较高，为了满足30天工作时间要求，在为所述装置供电时，多采用体积容量较大的铅酸电池或胶体电池，为电池 供电的太阳能板需求的功率也相应较大，导致了所述装置的成本比较高。
2)所述装置安装麻烦，费事费力。所述设备体积大且重量大，一般整套设备的重量可以达到40公斤以上，要安装到较高的输电线路上，输电线路一般架设在输电线路铁塔上，至少需要3ˉ4人配合完成且要借助轮滑等工具，尤其在一些偏远的山区劣势更为突出。
3)所述装置集成度差，为了实现监测的各个功能，所述装置需要多个不同的功能模块组合在一起，设计成本高。所述装置从功能上一般包括：带有编解码的数字信号处理(DSP)或ARM芯片、通信传输模块、存储芯片、模拟摄像机及电源***等几个部分，属于模块式组合，所述装置的各个功能模块之间相互独立，设计成本高且集成度低。
因此，如何能够在对输电线路进行图像监测时，提供低功耗和低成本、易于安装且集成度高的输电线路监测装置成为了一个亟待解决的问题。

有鉴于此，本发明实施例提供一种输电线路的图像监测装置，该装置能够在对输电线路进行图像监测时，降低功耗和成本，易于安装且集成度高。

以下举一个具体例子说明。
在该具体例子中，所述SoC可以采用高通公司的型号为MSM8916的芯片实现，在SoC中配置客户识别模块(SIM)卡。所述SoC运行安卓***，在SoC集成了USB模块、WiFi模块、图像采集与编码单元和4G通信模块，支持LTE制式，同时支持GPS定位，集成具有MIPI接口的摄像头为800万像素。
图3为本发明实施例提供的输电线路的图像监测方法具体例子流程图，其具体步骤为：
步骤301～303、输电线路的图像监测装置启动进行初始化，其中的SoC启动无线通信网络，所述装置自动进行通信网络校对时，获取当前通信网络的时钟，同时与当前通信网络的文件传输协议(FTP)服务器进行信息交互，获取服务器端设备的各种参数；
各种参数包括服务器端设备开关时间、拍照次数、图片像素等配置参数，按照参数设定的工作方式进行定时拍照及传输。
在该步骤中，拍照图片存储为JPEG格式，根据不同的客户需求设定不同的图片大小及分辨率等；
在该步骤中，SoC的内部存储空间可以设定，比如为1G，并且可以扩展大容量TF卡，最大128G空间；
步骤304、SoC配置完成后，就进入休眠模式，最大程度节省电能；
步骤305～307、SoC接收到通信网络发送的远程指令时，被唤醒，根据指令触发拍照或触发定时拍照；
步骤308、SoC启动摄像头拍照；
在该步骤中，监测装置在安装时根据不同的场景调整拍照角度，SoC的WiFi接口与现场调试工具进行连接，可以实时获取到拍摄图片并显示到手持调试工具屏幕上，使得现场安装更加便捷；
步骤309～310、SoC将所获取的输电线路图像进行编码后，通过无线方式输出并判断是否传输完成，如果否，继续传输，如果是，则返回步骤304。
采用本发明实施例的监测装置功耗低，因此配置的储能模块为10AH磷酸铁锂电池，体积重量较采用背景技术的监测装置使用的铅酸或胶体电池大幅度减小，工作时间却可以达到30天以上。
可以看出，采用本发明实施例提供的监测装置，大大降低了设计成本；同时集成芯片的设计也进一步缩小了监测装置体积和***电源的容量，使得监测装置做到一体化设计。在监测装置中集成了AP+BP，使得监测装置资源更丰富，图像处理更方便。
本发明实施例中的SoC是一个的集成了信号处理功能、射频、基带及图像采集功能和休眠控制等功能的片上***，而不是采用已有可以直 接使用的已经集成了功能的片上***，其中，信号处理功能采用基带单元及射频单元完成，图像采集功能由图像采集与编码模块完成。本发明实施例提供的SoC还进一步设置集成了无线通信功能及休眠功能，从而使得使用更加方便。本发明不仅限于采用太阳能充电的供电方式，其它如感应取电、交直流取电等供电方式均应包含在本发明的保护范围之内。
以上所述的具体实施例，对本发明的目的、技术方案和有益效果进行了进一步详细说明，所应理解的是，以上所述仅为本发明的具体实施例而已，并不用于限制本发明，凡在本发明的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
