具体实施方式
本发明提供的这种针对电能表软件的模块化设计方法，包括电能表软件分层设计、电能表软件模块定义、模块交互定义、软件模块配置管理和电能表软件最小系统；电能表软件分层设计用于将电能表软件进行分层设计，并定义各层级的内容和调用规则；电能表软件模块定义用于建立统一的软件功能模块模型；模块交互定义用于定义各个软件模块之间的数据交互规则；软件模块配置管理用于对各个软件模块进行功能配置选项的宏定义；电能表软件最小系统用于定义电能表软件的最小配置方案。
其中，电能表软件分层设计(如图1所示)用于将电能表软件分为MCU驱动层、设备驱动层、虚拟设备层、系统层和应用层；MCU驱动层用于MCU驱动开发，根据电能表设计需求对MCU驱动进行抽象并形成标准的驱动接口供上层调用；设备驱动层用于电能表外设驱动开发并形成标准的设备驱动接口供上层调用；虚拟设备层用于共用外设的抽象化设计；系统层用于电能表软件任务调度、文件存储管理和模块之间消息传递；应用层用于应用功能模块的实现。整个电能表软件由5层组成，从下至上分别为MCU驱动层、外设驱动层、虚拟设备层、系统层、应用层。下层为上层提供标准化的驱动接口，层间调用是单向调用关系，即只能上层访问下层的接口，禁止下层访问上层接口。硬件平台移植过程中，一般只影响MCU驱动层和外设驱动层，虚拟设备层、系统层、应用层基本不受影响。这种分层设计方法能够加快平台切换时的软件开发效率。
电能表软件模块定义用于建立统一的软件功能模块模型，将各软件功能模块的对外接口统一进行定义；比如，各功能模块对外接口统一为XX_GET(数据读访问)、XX_SET(数据写访问)，XX_ACTION(方法访问)，XX_INIT(模块初始化)，XX_TASK(模块主任务)，从而方便模块之间的调用和数据交互等。
模块交互定义包括数据交互、方法交互和内部对象标识定义；数据交互为通过数据对象标识进行访问，访问结果为数据内容及数据格式属性信息；方法交互为通过方法对象标识及输入数据信息进行方法访问，返回方法执行结果及输出数据信息；内部对象标识为对数据、方法对象标识进行统一标准化命名。
软件模块配置管理用于对各功能模块进行功能配置选项宏定义，每个功能模块都提供一个标准的功能配置头文件(比如每个功能模块都提供一个XX_Config.h功能配置头文件)，对功能模块进行功能配置，同时电表整体定义一个标准的表型配置头文件(比如电表整体定义一个MeterConfig.h表型配置头文件)，对表型功能进行配置管理。
所述的电能表软件最小系统包括MCU驱动层、设备驱动层、虚拟设备层、系统层、法定计量功能模块、显示功能模块和通信协议模块；其中MCU驱动层包括针对具体硬件平台MCU的驱动程序；其中设备驱动层包括针对具体硬件平台外设的驱动程序；其中虚拟设备层包括液晶、报警LED灯等共用外设的设备抽象程序；其中系统层包括任务调度、文件存储管理、模块之间消息传递程序；其中法定计量功能模块包括电能量计量、系统时钟程序；其中显示功能模块包括按键响应、数据显示程序；其中通信协议模块包括数据通信交互协议的处理程序，通信协议可配置选择为DL/T645-2007、DL/T698.45、IEC62056。
如图2所示为本发明方法的应用层功能模块统一模型的示意图：应用 层功能模块采用了标准化模型定义，一个功能模块由以下几部分内容组成：子功能模块实现、模块数据对象列表、模块方法对象列表、模块对外接口函数、模块功能配置文件。其中模块对外接口标准化为5个接口函数，分别是：模块初始化接口(XX_Init)、模块主任务接口函数(XX_Task)、模块数据读访问接口函数(XX_Get)、模块数据写访问接口函数(XX_Set)、模块方法访问接口函数(XX_Action)。
如图3所示为本发明方法的模块之间数据交互的示意图：从图3可以看出，应用层功能模块之间交互统一通过对象标识进行访问，数据访问通过数据对象标识，方法访问通过方法对象标识，模块之间交互访问时通过一个公共的交互路由中心进行对象标识解析路由，通过交互路由中心，能够大大简化模块之间的交互接口。图中过程标号①②③④为XX模块访问YY模块的访问流程。①为XX模块发起对象访问请求；②为交互路由中心对访问请求进行解析路由，调用YY模块的对象访问接口；③YY模块进行对象访问操作处理；④对象访问操作结果返回到交互路由中心，最后返回到交互访问发起者XX模块。图中过程标号⑤⑥⑦⑧为YY模块访问XX模块的访问流程，其处理流程同①②③④。
如图4所示为本发明方法的软件模块配置管理的示意图：从图4可以看出，各产品表型电能表软件由最小系统和扩展功能模块进行灵活组合配置。定义电能表软件整体配置文件Meter_Config.h，用于电表功能模块选配；各功能模块分别定义配置文件XX_Config.h，用于各功能模块功能定义选配。最小系统由底层驱动层、系统层、法定计量模块、通信协议处理模块、显示模块组成，定义最小系统配置文件System_Config.h，用于最小系统相关配置，如硬件平台、计量方案、通信协议等。
