附图说明
为了更清楚地说明本申请或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
天然气的计量方式一般有体积计量、质量计量、能量计量三种。其中，质量计量一般用于压缩天然气的计量。美洲、欧洲、中东和亚洲的大多数国家都是采用能量计量的方式，国内目前还是以体积计量为主。但是，考虑到国际天然气贸易对外接轨的需要，同时也为实现交易公平，体积计量向能量计量的转化也逐步在国内推进。首先提出变更的是上游的批发环节，批发环节的计价方式变更，必定会将计价的不公平推到用户端。
而要实现用户端燃气计价方式的变更也面临着很多困难，其中燃气热值的精准测量就是一大难点。而要将燃气热值测量功能加入在用户端实现则更为困难，故当前终端用户使用的燃气表仍是通过计量燃气体积量进行计价的。即使可以实现能量计量的表具被研发出来，大批量的表具生产和更换也需要很长的周期。在这期间，终端用户的结算方式也需要得到改进。
因此，本申请提出一种适用于天然气的能量计量方法、装置、设备和存储介质。依旧沿用现有的表具，正常采集和上报用户端的体积使用量。而将能量计量的过程设置在服务器侧，根据每个用户对应的气源供应结构，计算其使用的天然气的热值，再结合燃气表上报的体积使用量，最终确定能量使用量，以实现能量计量。
图1为本申请提供的一种应用场景的示意图。如图1所示，在某个区域中，仅有一个气源(图1中的气源1)直接向该区域内的用户提供天然气。连接在气源侧的气源热值检测装置检测气源输出的天然气的热值，并按上传规则上传至服务器；连接在用户侧燃气管道上的终端燃气计量器具检测用户的天然气体积使用量，并按上传规则上传至服务器。气源侧的天然气热值即为用户侧的天然气热值，因而，服务器可以根据气源侧的天然气热值和用户的天然气体积使用量计算出用户的天然气能领使用量。作为示例，图1的场景仅体现了其中一种供气方式，更多的实现方式将在下文中进行说明。
本申请的具体实现方式可以参考以下各实施例。
图2为本申请一实施例提供的一种能量计量方法的流程图。本实施例的方法的执行主体可以为服务器等终端设备。如图2所示，本实施例的方法可以包括：
S201、获取用户在计量周期内的天然气的体积使用量。
在本申请中，“计量周期”指的是对用户使用的天然气进行能量使用量计算的周期，可以为一天、一周、一个月等。周期的长度、起止的具体时刻可以根据实际场景来决定，也可以根据实际情况进行调整。
本实施例的方法的执行主体服务器所获取的体积使用量数据可以是由用户侧的燃气体积量采集装置采集，并直接或间接发送的。服务器获取相关数据后可以对数据进行解析和保存。
用户侧的燃气体积量采集装置，可以为民用燃气表、工商业燃气表、工 商业流量计等。民用表可以为普通皮膜表、IC卡表、微功率无线表、物联网表、NB-IoT表等燃气表；工商业燃气表可以为G6至G40的工商业燃气表；工商业流量计可以为DN25至DN200的工商业流量计。
燃气体积量采集装置基于自身的原理计量所对应的用户的燃气使用量，并上传至服务器，上传的信息中可以包含装置对应的设备号、上传周期内的天然气体积使用量或累积的天然气体积使用量等数据。
具备通信功能的表具一般可以自动上传数据，有固定或可调的上传周期；不具备通信功能的燃气表一般没有自动上传的功能，需要人工辅助上传，也有人工辅助上传的周期。因此，这里引入“上传周期”这一概念。与上述的“计量周期”相似的，周期的长度可以为一天、一周、一个月等，起止的具体时刻可以根据实际场景来决定，也可以根据实际情况进行调整。
图3为本申请一实施例提供的服务器侧从用户侧获取天然气体积使用量相关数据的流程示意图。
对于具备通信功能的表具，服务器按照表具的数据上传周期接收无线远程上传的数据，解析出其中的有效数据，并进行存储。
对于基表、IC卡表等不具备通信功能的燃气表，可以采用人工拍照上传的方式，定期向服务器传输体积使用量数据。具体的，可以使用摄像机、智能手机等具有图像采集功能的设备对表具进行拍照、录像等图像采集操作，通过可与服务器通信的终端设备向服务器发送采集的图像或视频数据，以便使服务器对图像或视频数据进行图像处理，以获取其中包含的用户信息(表具信息)天然气体积使用量信息。例如，通过智能手机的终端应用、小程序等将图像数据上传至服务器。服务器从指定接口接收小程序或者终端应用上传的燃气表正面照片，并解析照片中的燃气表号和体积使用量等相关数据，并进行存储。
对于物联网表、NB-Iot表、集中抄读的微功率无线表具等，可以通过专用的集中抄表设备采集天然气体积使用量数据后导入服务器。服务器从指定的数据导入接口导入手持抄表设备的抄表数据，解析出其中的有效数据并进行存储。
需要说明的是，计量周期与上传周期可能是一样的，也可能是不一样的。可以对所有表具采用统一的计量周期，也可以根据上传周期确定计量周期。
例如，对于基表、IC卡表及手持设备集中抄表的表具，可以将上传周期确定为计量周期，设定为一个季度或者2个月等。
又例如，物联网表、NB-Iot表等的计量周期可以设置为一天或多天。
S202、确定计量周期内每个发布周期发布的各类气源的热值。
本实施例的方法的执行主体服务器所获取的气源热值数据可以是由气源侧的气源热值检测装置采集并发送的。服务器获取相关数据后可以对数据进行保存。
具体的，气源热值检测装置可以为官方的监管中心的检测装置，对气源热值数据进行检测和定期的发布。一般，发布的热值数值为发布周期内的平均热值，或者发布周期内的多次检测得到的多个热值数据。
在本申请中，“发布周期”指的是对气源的天然气热值进行发布的周期，可以是一小时或者一天等。发布周期的长度、起止的具体时刻可以根据实际场景来决定。
另外，不同气源的发布周期也可能不同。
S203、根据用户对应的气源供应结构、每个发布周期发布的各类气源的热值，确定用户所使用的天然气的热值。
其中，气源供应结构用于指示用户所使用的天然气的气源的种类、数量，以及供气方式。例如，某个用户由哪几个气源供应天然气；若多个气源供气，供气方式是合并供应还是单独间隔供应等。
可以理解的是，气源不同，其组成成分不同，对应的热值也就不同。不同气源、同样气源的不同供气方式都会影响到用户使用的天然气的成分，故其对应热值也会不同。
确定了用户对应的气源供应结构，即可大致确定用户使用的天然气的成分或各气源成分的配比，再结合各类气源的热值，即可确定用户使用的天然气的热值。
用户所使用的天然气的热值的更新周期可以与气源热值的发布周期一致，即在每个发布周期结束后，获取到气源热值时即执行一次本步骤，确定用户使用的天然气的热值；也可以与发布周期不一致，例如在多个发布周期后才计算一次用户使用的天然气的热值。
S204、根据用户在计量周期内的天然气的体积使用量、用户所使用的天 然气的热值，确定用户在计量周期内的天然气能量使用量。
天然气的能量与体积、热值有稳定的对应关系，可以用公式表示如下：
E＝H×Q     (1)
式(1)中，E表示能量，H表示热值，Q表示体积。本申请中其它公式中也将采用此表示方式来指示相应的量，同时采用上标或下标来表示对应量的计量条件。如上述的，计量周期、更新周期、上传周期等分别对应于上述三个量，即每个量都带有计量的时间条件(式(1)中没有体现时间，实际默认是同样时间范围内的量)。
发布周期、更新周期、计量周期、上传周期可能一致也可能不一致，对应的实际算法公式需要考虑时间因素。
本实施例提供的能量计量方法包括：获取用户在计量周期内的天然气的体积使用量；确定计量周期内每个发布周期发布的各类气源的热值；根据用户对应的气源供应结构、每个发布周期发布的各类气源的热值，确定用户所使用的天然气的热值；气源供应结构用于指示用户所使用的天然气的气源的种类、数量，以及供气方式；根据用户在计量周期内的天然气的体积使用量、用户所使用的天然气的热值，确定用户在计量周期内的天然气能量使用量。根据用户对应的气源供应结构，可以确定用户使用的天然气对应的气源的构成方式，进而可以根据各气源的热值确定用户使用的天然气的热值，再根据用户的天然气体积使用量，即可得到能量使用量。如此，即可实现用户端使用的天然气的能量计量。实现上下游计费方式的统一，可以减少天然气输差。
根据上述的分析可以确定，对应相同气源供应结构的用户，使用的天然气的热值相同。基于这一特性，可以将用户按照气源供应结构进行分类，将气源供应结构相同的用户分入同一类，形成抽象的计费区。每次针对每个计费区统一计算使用的天然气的热值并存储，以便对计费区内的用户进行能量计量时使用。这样可以简化服务器中的计算量，提高处理效率。
具体的，可以根据目标区域中各用户对应的气源供应结构，将目标区域中的用户划分为多个计费区。其中，每个计费区中的气源供应结构相同。
相应的，上述的步骤S203根据用户对应的气源供应结构、每个发布周期发布的各类气源的热值，确定用户所使用的天然气的热值，具体可以包括：针对每个计费区，根据计费区对应的气源供应结构、每个发布周期发布的各 类气源的热值，确定计费区对应的天然气热值；根据用户对应的气源供应结构，确定用户所属的计费区；根据用户所属的计费区的天然气热值，确定用户所使用的天然气的热值。
本申请中所说的“目标区域”指的可以是服务器所管理的用户所在的区域。具体可以是地理上的分区，例如某市；或者某个燃气公司所管辖区域；或者某个气源所供应的区域等。
为了便于管理，可以在划分计费区后，针对每个计费区内的用户侧的体积量采集设备增加其所在计费区的标识。例如为每个计费区设定编号，将此编号与用户侧的采集设备的身份标识进行关联存储。
当需要对某个用户进行能量计量时，根据其身份标识关联的编号即可确定其所属计费区。直接获取该计费区的热值数据，即可用于对该用户的能量计量。
根据气源供应结构不同，每个用户使用的天然气的热值或每个计费区的热值的计算方式也有所不同。
可以理解的是，某个或某几个小区的气源供应结构可能是相同的，也就是说计费区也可能体现为地理上的聚集区域。
在另一种实现方式中，上述的步骤S203、S204还可以以另一种方式实现用户在计量周期内的天然气的能量使用量，具体可以包括：根据目标区域中各用户对应的气源供应结构，将目标区域中的用户划分为多个计费区；针对每个计费区，获取该计费区在计量周期内的总天然气体积使用量；根据用户对应的气源供应结构，确定用户所属的计费区；根据用户所属的计费区在计量周期内的总天然气体积使用量、气源热值、计费区内各用户在计量周期内的天然气的体积使用量、用户在计量周期内的天然气的体积使用量，确定用户在计量周期内的天然气的能量使用量。
即，不单独计算计费区内的天然气热值，而根据用户所属的计费区在计量周期内的总天然气体积使用量、气源热值，计算计费区在计量周期内的总天然气能量使用量，利用用户在计费区内的天然气体积使用量的占比作为用户在计费区内的天然气的能量使用量的占比，确定用户在计量周期内的天然气的能量使用量。
具体的，可以通过在计费区的燃气入口处设置流量计量装置，对计费区 的总天然气体积使用量进行计量。
在一些实施例中，上述的针对每个计费区，根据计费区对应的气源供应结构、每个发布周期发布的各类气源的热值，确定计费区对应的天然气热值，可以包括：针对每个计费区，若计费区内有唯一气源向各用户直接供应天然气，则根据每个发布周期发布的唯一气源的热值，确定计费区对应的天然气热值。
图4为本申请一实施例提供的一种气源供应结构的示意图。如图4所示的，供气气源为一个，气源固定，热值稳定，且直接持续向用户侧供气。这种气源供应结构下，气源侧的气体成分与用户侧的气体成分始终一致。因而，气源的热值即为用户侧使用的天然气热值。采用与此相同的气源供应结构的用户即可划入同一计费区。假设在更新周期内有n个发布周期，即更新周期为发布周期长度的n倍，则该计费区对应的天然气热值的计算公式如下：
Figure PCTCN2021128230-appb-000001
式(2)中，H s表示一个更新周期更新的计费区对应的天然气热值，H si表示在更新周期内第i个发布周期发布的气源热值。
针对每个计费区，根据计费区对应的气源供应结构、每个发布周期发布的各类气源的热值，确定计费区对应的天然气热值，可以包括：针对每个计费区，若计费区内有至少两个气源交替向各用户直接供应天然气，则根据至少两个气源各自的供气时间、每个发布周期发布的至少两个气源的热值，确定计费区对应的天然气热值。
图5为本申请一实施例提供的另一种气源供应结构的示意图。如图5所示的，供气气源为两个，气体流向相同，在不同的时间段分别使用某一气源单独向用户侧供气，在不同时段之间对各气源进行切换。这种气源供应结构下，在每个时间段内，气源侧供气的气源的气体成分与用户侧的气体成分始终一致。因而，用户侧使用的天然气热值与气源侧各气源的热值和供气时间相关。采用与此相同的气源供应结构的用户即可划入同一计费区。假设在更新周期内有n个气源1的发布周期、m个气源2的发布周期，即更新周期为气源1发布周期长度的n倍、气源2发布周期长度的m倍，则该计费区对应的天然气热值的计算公式如下：
Figure PCTCN2021128230-appb-000002
式(3)中，m、n均为大于1的数，H s表示一个更新周期更新的计费区对应的天然气热值，H 1si表示在更新周期内第i个发布周期发布的气源1的热值，H 2sj表示在更新周期内第j个发布周期发布的气源2的热值。
若m、n均为小于1的数，则更新周期小于发布周期，则可以根据具体的周期长度，判断更新周期落入哪个气源的供气时间段内。若某个更新周期落入气源1的供气时间段内，则该更新周期内计费区对应的天然气热值为气源1在此时间段内的热值。
或者，当上传周期较短，或可以上传用户天然气使用时间时，则可以根据使用天然气的时间、各气源的供应时间，更为精准的截取使用燃气时对应的热值。
在另一些实施例中，上述的针对每个计费区，根据计费区对应的气源供应结构、每个发布周期发布的各类气源的热值，确定计费区对应的天然气热值，可以包括：针对每个计费区，若计费区内有至少两个气源的一部分气体共同向各用户供应天然气，且至少两个气源的另一部分气体各自单独供应其它计费区，则获取至少两个气源的另一部分气体供应的其它各计费区的体积使用量；根据至少两个气源的另一部分气体供应的其它各计费区的体积使用量、每个发布周期发布的至少两个气源的热值，确定计费区对应的天然气热值。
图6为本申请一实施例提供的另一种气源供应结构的示意图。如图6所示的，供气气源为2个(分别为1和2)，不同数量和质量的气体传输至各计费区(4、5、6、7)，在计费区6的入口汇聚，共同向计费区6供气。计费区4、5、7的气源结构与图3类似。计费区6相当于2个气源同时向用户侧供气，但供气量不一定相同，假设在更新周期内有n个气源1的发布周期、m个气源2的发布周期，即更新周期为气源1发布周期长度的n倍、气源2发布周期长度的m倍，则计费区6对应的天然气热值的计算公式如下：
H s＝E/Q 6     (4)
Figure PCTCN2021128230-appb-000003
Q 61＝Q 1-Q 4-Q 5   (6)
Q 62＝Q 2-Q 7   (7)
式(4)-(7)中，m、n均为大于1的数，H s表示一个更新周期更新的计费区对应的天然气热值，E表示一个更新周期流经计费区6的天然气能量，Q 6表示一个更新周期流经计费区6的燃气体积量，Q 61表示气源1输入至计费区6的气体体积量，Q 62表示气源2输入至计费区6的气体体积量，Q 1表示一个更新周期内气源1输出的气体体积量，Q 2表示一个更新周期内气源2输出的气体体积量，Q 4表示气源1输入至计费区4的气体体积量，Q 5表示气源1输入至计费区5的气体体积量，Q 7表示气源2输入至计费区7的气体体积量，H 1si表示在更新周期内第i个发布周期发布的气源1的热值，H 2sj表示在更新周期内第j个发布周期发布的气源2的热值。
其中，Q 4、Q 5、Q 7可以通过设置在各计费区入口处的流量计获取。实际上，Q 6也可以通过设置在计费区6的入口处的流量计获取。但是，这样只能获取到总流量，不能确定气源1和气源2的气体的占比，计算得到的热值误差较大。利用上述的方法分别对气源1和气源2的能量进行单独计算再确定总能量，可以使天然气热值更精确。
在另一些实施例中，上述的针对每个计费区，根据计费区对应的气源供应结构、每个发布周期发布的各类气源的热值，确定计费区对应的天然气热值，可以包括：针对每个计费区，若计费区内有至少两个气源共同向各用户供应天然气，则获取计量周期内至少两个气源的输送体积；根据计量周期内至少两个气源的输送体积、每个发布周期发布的至少两个气源的热值，确定计费区对应的天然气热值。
气源的输送体积可以通过设置在气源侧的气源体积量采集模块进行计量，并将体积数据按照体积上传周期上传至服务器。体积上传周期可以是1小时、1天等。
具体的，可以基于中、高压流量计计量的工况体积、温度检测装置采集到的输气管道内的温度、压力检测装置采集到的输气管道内的压力，确定气源的标况体积。
图7为本申请一实施例提供的另一种气源供应结构的示意图。如图7所示的，供气气源为两个，气体流向相同，共同向用户侧供气。这种气源供应结构下，气源侧供气的两气源的混合气体成分与用户侧的气体成分始终一致。采用与此相同的气源供应结构的用户即可划入同一计费区。假设在体积上传 周期内有n个气源1的发布周期、m个气源2的发布周期，即体积上传周期为气源1发布周期长度的n倍、气源2发布周期长度的m倍，则该计费区对应的天然气热值的计算公式如下：
H s＝E/(Q 1+Q 2)      (8)
Figure PCTCN2021128230-appb-000004
式(8)-(9)中，m、n均为大于1的数，H s表示一个更新周期更新的计费区对应的天然气热值，E表示一个更新周期流经计费区的天然气能量，H 1si表示在更新周期内第i个发布周期发布的气源1的热值，H 2sj表示在更新周期内第j个发布周期发布的气源2的热值，Q 1表示一个更新周期内气源1输出的气体体积量，Q 2表示一个更新周期内气源2输出的气体体积量。
假设气源1的体积上传周期与发布周期相同，且气源2的体积上传周期与发布周期相同，且长度均小于计量周期的长度，则该计费区对应的天然气热值的计算公式如下：
H s＝E/(Q 1+Q 2)     (10)
Figure PCTCN2021128230-appb-000005
由于气体的特性，其密度较小，流动性强。因而，不同气源的天然气混合后供应到各用户的天然气不一定完全均匀。对于普通家庭用户来说，因为天然气用量较小，直接采用上述的方法，以计费区的平均热值作为用户使用的天然气热值，误差较小。然而，某些计费区内可能会有大型的工业用户(例如电厂、钢铁厂等)。这些大型工业用户的天然气用量较大，可能对整个计费区的平均热值影响较大，因此可以单独处理。
对应的在确定计费区对应的天然气热值之前，上述的方法还包括：确定计费区内是否存在工业用户；若计费区内存在工业用户，则获取工业用户在计量周期内的天然气能量使用量；针对每个计费区，根据该计费区对应的气源供应结构、每个发布周期发布的各类气源的热值，确定该计费区对应的天然气热值，包括：针对每个计费区，若计费区内存在工业用户，则根据工业用户在计量周期内的天然气能量使用量、每个发布周期发布的各类气源的热值，确定计费区的天然气的热值。
一般，工业用户会使用热值采集设备对使用的天然气的热值、体积使用 量等进行分析检测。与普通用户的表具类似的，检测的热值和体积使用量可以上传到服务器。服务器则可以根据工业用户在计量周期内的天然气日均体积使用量、天然气热值，确定工业用户在计量周期内的天然气能量使用量，进而确定计费区内其它普通用户在计量周期内的天然气能量使用量、计费区的天然气的热值。在这里，计费区的天然气热值指的是工业用户以外的普通用户使用的天然气的平均热值。
具体的，对于图6对应的实施例，如果计费区6内存在工业用户，且安装了热值采集设备，则计费区6内其他普通用户的热值计算公式如下：

Figure PCTCN2021128230-appb-000009
式(14)-(15)中，Q k表示工业用户k的日累积用气量，H k表示工业用户k的日平均热值。
具体的，上述的获取工业用户在计量周期内的天然气能量使用量，可以包括：获取工业用户在计量周期内的天然气日均体积使用量、天然气热值；根据计量周期内的天然气日均体积使用量、天然气热值，确定工业用户在计量周期内的天然气能量使用量。
工业用户安装的热值采集设备，可以采集到工业用户的日平均热值和用气量，用以计算工业用户的能量消耗，对于使用混气的计费区，可以更精准计费区内其他表具的赋值热值。其中，对于大型钢铁厂、发电厂等工业用户，安装的热值采集设备可以为在线气相色谱分析仪(TGC)等。
