3.基于物联网智能感知技术的电力通信移动运维方法
电力通信移动运维是电力通信运维的重要组成，基于电力网通信运维管理系统软件框架平台，使用电力网统一资源数据模型，综合了数据存储、数据采集、数据比对、数据展示、结果回发等功能，并与设备台账、工单管理系统实时交互。具体的步骤如下：
第一步：数据存储
电力通信移动运维是一类通信网运维的总称，所以在本运维方法中选择的初始化存储应该具有通信网运维的普遍适用性，运维工单、作业指导书、设备台账等数据资源是电力通信移动运维普遍存在且数据存储、采集、比对较为容易资源，本运维方法将采用运维工单、作业指导书、设备台账作为初始化存储资源进行电力通信移动运维管理基础数据，其他数据则采用手工配置的方法进行设置和采集。
用户登录系统按照设定好的移动运维任务，系统将按照设置任务情况进行运维工单、作业指导书、设备台账数据的展示。运维任务中的运维工单、作业指导书、设备台账数据展示是否合理决定了运维工作是否规范准确，所以在展示数据时将会按照实际运维任务进行工单、作业指导书、设备台账数据的关联。
由于手持终端是通过公共网络进行通信的，考虑到数据安全性，手持终端1采用外置的外存储器4进行数据存储，因此电路设计扩展了4M SRAM和16M Flash，存储电路如图4所示。为了方便程序调用和代码固化应用，我们使用了bank0和bank1的地址空间，可以通过JP701跳线将CS0和CS1分别分配给SRAM和Flash。在程序调用时分配SRAM为bank0地址，因为bank0可以进行中断向量重新映射操作。当代码固化到Flash时，分配Flash为bank0地址，SRAM为bank1地址，因为bank0可以用来引导程序的运行。若使用bank0引导程序运 行，可将JP700短接到outside端，使系统复位时boot1和boot0为1。
存储器连接使用了16位总线方式，数据总线使用了D0-D15，地址总线使用了A1-A20，对于16位的SRAM，BLS0和BLS1信号用于控制低字节和高字节的写作。
第二步：数据采集
数据采集主要是进行运维场地、运维设备、运维线路的确认，确保运维工作准确、规范开展的重要先决条件。具体定位功能如下：
报警设备、线路的位置信息初始化存储，所有移动运维任务在初始化阶段均提供完成的地理位置、设备台账信息；
采用GPS定位和RFID、二维码识别技术、iODF智能光纤配线架、图像识别技术实现对于移动运维人员位置读取，设备信息读取。
该系统采集的是运维设备的实时数据，主要包括:设备台账、报警信息、工单信息等数据。在每台电力通信设备上安装数据采集终端(二维码、RFID卡等)，利用无线、有线方式完成内部管理系统与手持终端采集系统的通信，实现双向实时的设备信息交互。
第三步：数据交互
数据采集终端通过蓝牙实现与手持终端的数据交互和数据采集指令传输，同时根据手持终端自带的数据传输接口也可定制开发手持终端与数据采集终端一体式终端设备。由于蓝牙具有适用性广、抗干扰能力强、传输数据格式多样、能耗低等特点，所以本部分只对蓝牙连接的分体式数据采集终端与手持终端对接过程中数据采集终端的蓝牙模块进行说明。
基于蓝牙无线传输的数据采集系统是实现数据采集终端与手持终端之间数 据交互的基础手段，整个装置由前端数据采集、传送部分以及末端的数据接受部分组成。前端数据采集部分由位于现场的传感器、信号放大电路、A/D转换器、单片机、存储器、串口通信等构成,传送部分主要利用自带微带天线的蓝牙模块进行数据的无线传输；末端通过蓝牙模块、串口通信传输将数据送到上位的智能手机进一步处理。
AT89C51单片机作为下位的数据采集终端5的主控制器，传感器获得的信号经过放大后送入12位A/D转换器AD574A进行A/D转换，然后将转换后的数据存储到RAM芯片6264中。下位机可以主动地或者在接收上位机通过蓝牙模块发送的传送数据指令后，将6264中存储的数据按照HCI-RS232传输协议进行数据定义，通过MAX3232进行电平转换后送至蓝牙模块，由篮牙模块将数据传送到空间，同时上位机的蓝牙模块对此数据进行接收,再通过MAX3232电平转换后传送至智能手机，从而完成蓝牙无线数据的交换。
信号放大电路主要采用高共模抑制比放大电路，它由三个集成运算放大器组成，本设计中选用的集成运算放大器TL082具有高精度、低漂移的特性。
AT89C51与A/D转换器AD574A及外扩数据存储器6264的接口示意图如图5所示。AT89C51通过地址译码器74LS138、地址锁存器74LS373，对A/D转换器、数据存储器进行地址选择。
蓝牙模块与AT89C51串口之间采用蓝牙模块提供的RS232传输层接口实现通信，需要外接电路实现电平转换，由于蓝牙模块需3.3V供电，因此这里选用MAX3232芯片作电平转换芯片。另外，为了将5V输入电压转换为3.3V电压，选用电源稳压芯片7301为蓝牙模块供电。AT89C51通过MAX3232与蓝牙模块的接口示意图如图6所示。
在软件实现上本设计的软件主要包括两部分：数据采集和蓝牙通信，采用汇编语言和C51混合编程。为了保证数据采集的实时性，数据采集部分采用汇编语言编程，单片机采用定时采样，具体选择定时方式2，定时为100微秒，定时结束后，进行A/D转换，单片机采用查询的方式读取AD574A的转换结果，然后将转换后的数据存至外扩存储器6264中。另外，串行口工作在方式1，波特率为9600bps。蓝牙通信部分采用C51编程，主要实现利用主机控制器接口HCI层建立点对点的蓝牙异步无链接数据传输通道，当两个蓝牙模块链路建立成功后，就可以按照蓝牙规范规定的HCI数据分组格式收发数据。
两个蓝牙设备间进行数据通信是通过HCI分组实现的，HCI作为蓝牙软件协议堆栈中软硬件之间的接口，为上层提供了访问和控制蓝牙硬件的统一接口。HCI是通过分组(Packet)的方式来进行信息交换的。HCI分组有三种类型:指令分组(Command Packet)、事件分组(Event Packet)和数据分组(Data Packet)。
智能手机与数据采集终端的蓝牙模块用指令--应答方式进行通信，先发送指令分组；数据采集终端执行某一指令后，大多数情况下会返回给主机一个指令完成事件分组(Command Complete Event Packet)，该分组携带有指令完成的信息。有些分组不会返回指令完成事件，而返回指令状态事件分组(Command Status Event Packet)用以说明智能手机发出的指令己经被接收并开始处理。如果指令分组的参数有误，返回的指令状态事件分组就会给出相应的错误代码；数据分组分为异步无连接(Asynchronous Connectionless,ACL)数据分组和同步面向连接(Synchronization Connection Oriented,SCO)数据分组两种。在本发明中，仅涉及到数据通信，而没有涉及到语音通信，因此建立的是ACL链路。
单片机与蓝牙模块的软件接口，就是指单片机如何通过软件实现向蓝牙模块发送HCI指令，蓝牙模块又如何通过软件向单片机返回HCI事件以及两者之间如何实现数据传输。单片机和蓝牙模块间通信的过程是通过键入HCI指令，观察收到的HCI事件。当两个蓝牙模块建立链路成功后，就可以按照蓝牙规范规定的HCI数据包格式收发数据。
在通过蓝牙模块进行数据通信时，首先要进行蓝牙模块的初始化和HCI层流控设置。典型的蓝牙模块间的ACL数据通信流程有6个步骤:蓝牙模块自身初始化Init Bluetooth()、HCI流量控制设置Flow Set()、查询Inquiry()、建立连接Great Connection()、进行数据通信Data_Transmit(Data Length,HCI_Number)和断开连接Disconnect()。
初始化程序主要是单片机对蓝牙发送一系列命令分组。单片机每向蓝牙发送一个HCI命令分组就要接收蓝牙返回的事件分组，判断命令执行的情况。若返回事件分组不正确就要重新初始化蓝牙，直到完全正确。蓝牙设备在初始化完成之后，通过Set_Host_Controller_To_Host_Flow_Control指令打开流量控制，并通过Host Buffer Size指令来对流量控制进行配置，包括数据分组的长度等。此后，主设备查询周围的蓝牙设备，找到之后即可向其发出建立连接指令，建立ACL连接。成功建立连接之后就可以进行数据通信。通信完成后，主设备和从设备都可以发出断开连接的命令Disconnect。在上述过程中，查询过程不一定存在，所以这只是一般的流程模型。如果在任何一条指令分组发出后，返回错误的事件分组，则指令需重发直到正确为止。
第四步：数据比对
设备台账、工单等数据均采用标准化ID进行标示，所以数据比对主要是对 采集到的数据ID和系统初始化数据ID进行比对，确认运维的相关信息(如运维设备、运维线路和运维工作完成情况)。
本部分需要参与的模块有：采集数据读取模块、初始化数据读取模块、数据比对处理模块和比对结果存储展现模块。如图7所示：
(1)初始化数据读取服务
服务名：pm_readmodel；
初始化数据模型的读取、转发方式，类似于目前较为成熟的设备台账数据模型的读取方式，因为需要读取的数据模型不止初始化数据，所以将其作为一类独立的模型读取。
(2)采集数据读取服务
服务名：pm_monitor；
此服务和初始化数据模型的读取、转发方式类似，因为需要读取的数据需要和初始化数据进行比对，所以将其作为一类独立的模型读取。
(3)数据比对服务
服务名：pm_data comparison
数据比对服务负责将读取的数据按照初始化设置进行比对，并输出比对结果，(不同设备、线路在比对数据上可能出现不同，所以前期需要为不同设备、线路进行个性化初始化比对数据设置)
(4)数据比对结果存储展示
服务名：pm_data comparison results storage
负责对比对结果进行回传存储和展示，如果比对结果符合要求将进行有效数据展示(比对数据分为运维设备、线路定位比对和运维工作结果比对两个部 分；设备、线路定位比对符合要求后系统将直接调用对应的作业指导书进行展示，运维工作结果比对符合要求后系统将直接存储比对结果数据，并提示运维人员运维工作已经按照要求完成)，若比对结果不符合要求将直接提示不符合要求。
第五步：结果回发
在完成整个运维工作，并进行运维工作结果比对后，手持终端首先会对比对结果进行本地化存储，比对结果数据在本地化存储的存储将会以电力通信运维系统的工单数据模型和设备台账数据模型为基础进行数据存储；完成存储之后手持终端将利用3G、4G无线传输技术进行数据回传(回传数据主要是回传至后台服务器，后台服务器可以将数据和相应的电力通信运维系统进行数据交互；后期在完成数据对接的情况，回传数据可以直接回传至相关的电力通信运维系统，从而实现全网电力通信运维的无缝化管理。)。如果现场无法提供相关无线连接，可以在运维人员返回后进行数据无线回传和直连回传。
除上述实施例外，本发明还可以有其他实施方式，凡采用等同替换或等效变换形成的技术方案，均落在本发明要求的保护范围内。
