本申请的目的在于提供一种采用新型的NB-IoT通讯模组的智能燃气表。智能燃气表所采用的NB-IoT通讯模组燃气表专用模组，是一种将NB-IoT调制解调器内部的多个MCU中的一个MCU定义为智能燃气表MCU,将计量计费模块、阶梯气价计费单元、定时器、液晶显示屏、输入模块、红外传感器等全部嵌入NB-IoT通讯模组芯片内、智能燃气表的全部功能由NB-IoT的MCU芯片内的资源实现；在物联网智能燃气表看来就像一个独立的智能燃气表MCU一样，能够以OpenCPU的形式来进行业务处理，实现智能燃气表全部功能，并且能够完成NB-IoT通讯功能，智能燃气表专用NB-IoT通讯模组无需在NB-IoT通讯模组外附其他MCU，本发明解决了现在MCU智能控制板与NB-IoT通讯模组构成的物联网智能燃气表，其成本低、结构简单、功耗小，同时通过计量表增加了计量的准确性。
请参阅图1，图1为本申请提供的NB-IoT通讯模组内嵌程序的燃气表结构 框图。如图1所示，所述NB-IoT通讯模组内嵌程序的燃气表100包括NB-IoT通讯模组9、红外传感器1、电源模块2、阀门驱动模块3、计量计费模块4、输入模块5、定时器6、存储模块7以及液晶显示屏8。所述红外传感器1、电源模块2、阀门驱动模块3、计量计费模块4、输入模块5、定时器6、存储模块7以及液晶显示屏8均连接NB-IoT通讯模组9。该NB-IoT通讯模组9内配置有MCU芯片，以使得所述NB-IoT通讯模组被唤醒时切换至正常工作状态，并通过所述MCU芯片实现各项燃气业务功能。
具体地，所述NB-IoT通讯模组9的工作模式分为正常工作状态和低功耗状态。所述正常工作状态指的是一种以模块作为主处理器的应用方式，以OpenCPU的形式来进行业务处理，实现智能燃气表全部功能。这种方式可以简化用户对通信终端的开发流程，精简硬件结构设计，从而满足客户对成本、功耗、安全性等方面的需求。该正常工作状态无需外部处理器如MCU，存储器及离散和相关的设计费用，能够减小终端产品的实际尺寸,改善产品的市场性价比，提升产品竞争力，并且降低产品功耗，也能实现远程空中无线升级。其与传统外接MCU不同的是在使用过程中直接调用相关API接口函数即可，不需要通过串口如I/O输入输出端口转换对应指令以调用API接口。本申请中的API接口函数包括常用驱动接口(GPIO、UART、I2C、SPI、ADC、DAC)、KV接口(芯片内部flash接口)、DNS解析接口、数据下行接口回调接口、事件状态查询接口、常用传感器库接口等。
所述低功耗状态即PSM(Power Saving Mode，省电模式)是NB-IoT通讯模组9的一种低功耗模式，在低功耗状态下，待机功耗只有微安级别，能大大提升电池的使用年限。PSM模式指的是终端非业务期间深度休眠，不接收下行数据，只有终端主动发送上行数据(MO Data)时可接收IoT平台缓存的下行数据，适合对下行数据无时延要求的业务；终端设备功耗低，采取电池供电方式，如抄表业务。
红外传感器1用于感应生命体，如人使用燃气时产生燃气使用信号，所述NB-IoT通讯模组9内的MCU芯片检测到该燃气使用信号时控制计量计费模块4启动开始计量，若所述红外传感器1在感应人关闭燃气时产生燃气关闭信号，所述NB-IoT通讯模组9内的MCU芯片检测到该燃气关闭信号时控制计量计费模块4关闭，并通过计量计费模块计算从燃气使用信号产生到燃气关闭信号产生时 对应的燃气使用量、费用以及累计量。在本实施例中，所述红外传感器为通用型红外传感器，节省成本，也便于推广。
所述电源模块2用于为智能燃气表100供电，以减少智能燃气表100功耗。在本实施例中，所述电源模块2为锂电池。
所述阀门驱动模块3是用于辅助所述NB-IoT通讯模组9实现相关事件的控制功能，所述阀门驱动模块3包括阀门驱动器。
所述计量计费模块4还与所述红外传感器1连接，所述计量计费模块4用于计算从接收到燃气使用信号到燃气关闭信号时的燃气使用量以及用于计算所述燃气关闭信号对应的时刻的燃气累积使用量。在实际应用中，所述计量计费模块4配置有计费计量程序，所述计量计费模块4包括阶梯气价计费单元和机械脉冲计数燃气表；所述阶梯气价计费单元用于阶梯计量收费、用于确定若干组阶梯价格方案以及用于确定用户燃气使用的阶梯状态，其中，所述阶梯状态包括正阶梯和负阶梯中一种或多种。在本实施例中，所述阶梯气价计费单元为计费表和计量表组合，不仅集成多种功能，还降低成本。
所述输入模块5用于接收用户的输入信息以显示在所述液晶显示屏，所述输入模块5包括键盘、鼠标、虚拟按键以及拾音器中一种或多种。也就是说，所述输入模块5可实现用户手动输入，也可以实现语音输入。通过所述输入模块5的输入，以显示在所述液晶显示屏8。
所述液晶显示屏8包括LED液晶显示屏和OLED液晶显示屏中一种或多种，用于显示各项业务数据。
所述定时器6被配置超时时间，所述定时器6用于计时时长到达超时时间时唤醒所述NB-IoT通讯模组9切换至正常工作状态。
在本实施例中，所述存储模块7为flash存储器，用于缓存各种数据，也便于查找和调用。
基于上述NB-IoT通讯模组内嵌程序的燃气表从而实现数据处理方法。为了更进一步理解本申请的技术方案，用一具体实施例加以说明。
请参阅图2，图2为NB-IoT通讯模组内嵌程序的燃气表的数据处理方法。应该说明的是，本发明实施方式的NB-IoT通讯模组内嵌程序的燃气表的数据处理方法并不限于图2所示的流程图中的步骤及顺序，根据不同的需求，流程图中的步骤可以增加、移除或者改变顺序。如图2所示，所述NB-IoT通讯模组内嵌 程序的燃气表的数据处理方法包括：
S10、启动定时器开始计时，当计时时间达到超时时间时，所述定时器唤醒处于低功耗状态下的所述燃气表中的NB-IoT通讯模组。
在本实施例中，NB-IoT通讯模组处于低功耗状态，节省电量。触发所述NB-IoT通讯模组9工作，即由低功耗状态切换为正常工作状态具有两种方式，一种是外部中断以唤醒所述NB-IoT通讯模组9切换至正常工作状态，另一种是定时器6超时中断(定时器6的计时时长达到预定时刻如超时时间时)以唤醒所述NB-IoT通讯模组9切换至正常工作状态，如图3所示。当所述NB-IoT通讯模组9被唤醒时开始对各项任务进行处理，以实现各种功能。
定时器超时中断唤醒NB-IoT通讯模组9，具体为：
智能燃气表上电后，模块首先将内嵌智能燃气表功能的NB-IoT通讯模组9中的NB调制解调器、智能燃气表RAM、存储模块7等相关模块及接口进行赋能初始化，初始化后各模块进入休眠状态，当使用光电直读燃气表时，设置定时器6中断时间，定时器6中断后，表头直读接口程序对机械直读器中的数据进行取，定时器6中断时间可通过无线设置，也可通过程序初始化进行设置。当程序发生定时器6中断时，会根据一定时间间隔来执行相关功能，比较中断时刻的时间是否与预设功能时间相同，如果相同则设置相关功能的事件标志位，跳出中断后主函数会根据标志位完成对应事件功能。
S20、所述NB-IoT通讯模组切换为正常工作状态，以IIC通信方式获取存储在存储模块中的燃气消费信息，并将所述燃气消费信息发送至物联网平台。
在本实施例中，当时间达到预设的上传时间时，所述NB-IoT通讯模组切换为正常工作状态，NB-IoT通讯模组9被唤醒即上电，并执行初始化程序，MCU芯片会接着通讯协议通过对应的调制解调器上传一条数据给物联网平台。例如：以IIC通信方式获取存储在存储模块中的燃气消费信息，并将所述燃气消费信息发送至物联网平台。
如果程序检测出欠压、逆流等异常现象时，程序会进行报警并通过NB-IoT通讯模组9上传一条数据提醒使用者。在每次接收后台信息时，接受的信息中含有日历时间信息，会对智能燃气表的内部时钟自动进行校验，从而保证智能燃气表日历时钟的准确性。同时在定时器6中断中每隔一段时间系统会进行一次系统内部状态诊断，判断各个功能单元是否正常启动，各个拓展口是否被应用。如果 有某些功能单元出现异常，MCU芯片会接着通讯协议上传一条数据给云端后台通知相关人员进行维修操作。
S30、所述NB-IoT通讯模组接收所述物联网平台反馈的结果，并将该结果存储后切换为低功耗状态，以等待下一次被唤醒。
在本实施例中，所述NB-IoT通讯模组接收所述物联网平台反馈的结果，并将数据存储在flash存储器，用作参考依据，也便于调用和计算。当检测到任务完成时，则所述NB-IoT通讯模组自动切换为低功耗状态，以等待下一次被唤醒，这样不仅智能节省电量，还降低耗损，提高数据处理效率。
外部中断唤醒所述NB-IoT通讯模组，具体为：当检测到用户用气以产生中断信号时，所述NB-IoT通讯模组被唤醒以切换为正常工作状态；所述NB-IoT通讯模组获取并执行待执行任务，以实现计量计价的功能，并将计量计价后的相关数据存储在存储模块中；当所述NB-IoT通讯模组完成所述待执行任务时切换为低功耗状态，以等待下一次被唤醒。
也就是说，当使用脉冲计数燃气表时，程序会启动外部中断检测方式，当接收到脉冲信号时，程序会发生中断，通过中断的状态计算流量。得到流量后，把流量信息定时上传至物联网平台，同时数据存储程序可以将用量信息存储在数据存储模块中，该信息可以保存一个月，当智能模组完成数据采集及储存后，NB调试解调器初始化程序开始执行，同时利用NB-IoT网络将采集到的用量信息上传至物联网平台，如云平台。
例如：检测到用户用气时产生中断信号，根据中断信号唤醒所述NB-IoT通讯模组，使得NB-IoT通讯模组进行计量计价的功能，并将累计量和当前实际流量等数据存储在存储模块中。
进一步地，程序还可以根据需求设置事件，所述事件可配置为对数据上传、欠压报警、窃用报警、超小流报警、逆流报警等，当出现定时中断或外部中断如用气中断时运行程序会对上述事件进行检测。例如，定时中断发生后，程序会开始去检测有没有欠压，有没有到达数据上传的时间等。不管是定时中断，还是外部中断均会对事件标志位进行更改，更改之后跳出中断根据标志位进行相关的事件操作。NB-IoT通讯模组9被中断唤醒时首先判断中断类型，如果是外部中断再通过判断具体哪个端口引发中断，来设置相关功能的事件标志位，跳出中断后主函数会根据标志位完成对应事件功能。通过外部中断触发的功能主要有电源模 块2的电池电量检测功能、机械脉冲计数燃气表的燃气表功能，脉冲计数功能。如果各功能单元正常启动则模块进入休眠状态低功耗状态并开启定时器6，当NB-IoT通讯模组9侦听到发送来的消息或者程序设定的唤醒时间到达时NB-IoT通讯模组9会被唤醒，当NB-IoT通讯模组9被唤醒后，即处于正常工作状态，各个工作单元开始工作，其中通过上位机或物联网平台将数据传送给智能燃气表进行阀门控制，智能燃气表提取需要计算的数据传输给数据接口，将数据通过数据线经过调制、滤波等发送给上位机进行解析。
综上，本申请公开了NB-IoT通讯模组内嵌程序的燃气表及数据处理方法，本申请利用了内嵌了智能燃气表全部功能的NB-IoT通讯模组。该NB-IoT通讯模组是一种将燃气表机械脉冲计数燃气表、直读程序、脉冲计数模块及程序、可拓展接口及程序、阀门驱动模块、阶梯气价计费单元、定时器、液晶显示屏、输入模块等与NB-IoT通讯功能集成到一个MCU芯片一体的燃气表专用NB-IoT通讯模组，节省了一个外部MCU，显著的节约了成本，使得产品在市场竞争中更具竞争力，并且NB-IoT通讯模组内嵌燃气表程序主要以OpenCPU形式实现各业务对应的功能，可视为一个简单的操作系统进行项目开发，可以显著降低开发难度和工作量；本申请具有使用方便，功耗低，体积小，可靠性较高等优点，对于智能燃气表领域都具有较强的实用意义，通过红外传感器和计量表增加了流量计量的准确性。
当然，本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程，是可以通过计算机程序来指令相关硬件(如处理器，控制器等)来完成，所述的程序可存储于一计算机可读取的存储介质中，该程序在执行时可包括如上述各方法实施例的流程。其中所述的存储介质可为存储器、磁碟、光盘等。
