图 2A为本发明一实施例提供的数据传输方法的流程图。 如图 2A所示, 本实施例的方法包括:
步骤 201、 电力网关接收多个终端设备分别发送的第一数据帧。
其中, 本实施例的第一数据帧的源地址为发送第一数据帧的终端设备的 地址, 即终端设备地址, 目的地址为主站的地址, 每个第一数据帧的数据部 分包含一个终端设备的上报数据。
步骤 202、 电力网关解析每个第一数据帧, 获取并存储每个第一数据帧 中的上报数据。
其中, 所述上报数据可以是终端设备执行主站通过电力网关发送的操作 指令而返回的操作响应数据, 也可以是终端设备主动上报的数据。 其中, 终 端设备主动上报的数据可以是事件告警数据、 终端设备状态信息等。
其中, 电力网关可以将获取的上报数据存储在随机存储器 (Random Access Memory, RAM )或闪存(FLASH ) 中, 但不限于此。
步骤 203、 电力网关根据所存储的上报数据, 生成第二数据帧, 然后将 第二数据帧发送给主站。 其中, 本实施例的第二数据帧的源地址为电力网关的地址, 目的地址为 主站的地址, 所述第二数据帧的数据部分包含多个上报数据, 这些上报数据 来自于步骤 202中存储的第一数据帧的上报数据。 具体地, 当某个第二数据 帧中包含的上报数据来自于不同的终端设备时, 在第二数据帧的数据部分还 机能够对第二数据帧进行解析, 并区分和识别相应的上报数据来自于哪个终 端设备。
在本实施例中, 电力网关接收多个终端设备发送的第一数据帧, 并对每 个第一数据帧进行解析, 获取并存储第一数据帧中的上报数据, 然后根据所 存储的多个终端设备的上报数据生成第二数据帧, 将第二数据帧发送给主 站, 实现将终端设备的上报数据发送给主站的目的。 电力网关根据所存储的 多个终端设备的上报数据生成第二数据帧主要是指将所存储的多个终端设备 的上报数据封装在第二数据帧中的过程。
在本实施例中, 电力网关具有解析终端设备发送的第一数据帧并存储获 取的上报数据的功能, 电力网关不用再像现有技术那样每接收一个终端设备 的一个第一数据帧就要与主站建立连接并通过建立的连接转发给主站, 而是 可以存储多个终端设备的上报数据, 然后在与主站的一次连接过程中发送给 主站, 减少了与主站之间建立连接的次数, 进而减少了无线网络的通信流 量, 减少了无线网络通信资源的浪费。
进一步, 在本实施例中, 第二数据帧可以是一个也可以是多个。 第二数 据帧的个数可视电力网关需要上报给主站的上报数据的总数据量以及第二数 据帧的长度而定。 在本实施例中, 一个第二数据帧可以同时包括多个终端设 据帧上报给主站的技术方案相比, 可以减少电力网关向主站上报终端设备的 上报数据所使用的数据帧 (即第二数据帧) 的数量, 有利于减少主站和电力 网关之间的通信次数, 进一步可以降低无线网络通信资源的浪费。
其中, 电力网关和终端设备之间可以使用 DLMS协议进行通信, 但不限 进行通信。 同理, 电力网关和主站之间也可以使用 DLMS协议进行通信, 但 不限于此。 例如, 电力网关和主站之间还可以使用 Q / GDW 376.1-2009协议
8 进行通信。
其中, 如果电力网关和终端设备之间以及电力网关和主站之间使用
DLMS协议进行通信, 则第一数据帧可以是第一 DLMS帧, 第二数据帧可以 是第二 DLMS帧。
在本发明各实施例中, DLMS 帧的结构如图 2B 所示, 主要包括: 帧 头、 目的地址、 源地址、 控制域、 数据域、 校验、 帧结束。 其中 DLMS帧的 数据部分主要指数据域。
进一步, 电力网关可以确定上报数据是否均为非实时上报数据; 如果确 定结果为上报数据均为非实时上报数据, 则电力网关执行存储上报数据的操 作。 具体的, 电力网关可以根据上报数据的功能或者上报数据类型标识, 来 确定上报数据是否为非实时上报数据。 上报数据类型标识可以在数据帧的控 制域或数据域中携带, 用于指示该数据帧中的上报数据是实时上报数据或非 实时上报数据。 所述非实时上报数据包括告警等级小于预设门限的事件告警 数据或终端设备状态数据
进一步, 如果确定结果为多个上报数据中存在实时上报数据, 即不是每 个第一数据帧中的上报数据均为非实时上报数据, 则电力网关可以不存储实 时上报数据, 直接根据实时上报数据, 生成第二数据帧, 然后将第二数据帧 发送给主站, 但不限于此。 例如, 在不是每个第一数据帧中的上报数据均为 非实时上报数据的情况下, 电力网关还可以将接收到的实时上报数据和该实 时上报数据之前的非实时上报数据一起封装成第二数据帧发送给主站。
进一步, 电力网关将第二数据帧发送给主站之前, 主站和电力网关之间 的连接可以是断开的, 也可以是已经处于连接状态。 如果主站和电力网关之 间的连接是断开的, 则电力网关将第二数据帧发送给主站的过程包括: 电力 网关先建立到主站的连接, 然后通过所建立的连接将第二数据帧发送给主 站。
进一步, 电力网关可以预先设定接收周期, 然后在接收周期结束后根据 所存储的上报数据, 生成第二数据帧, 然后将第二数据帧发送给主站。 在该 实施方式中, 在每个接收周期结束之前, 电力网关接收终端设备发送的第一 数据帧, 从第一数据帧中解析出上报数据并存储上报数据, 而在每个接收周 期结束后, 电力网关将该接收周期内存储的上报数据封装在第二数据帧中发 送给主站。 在该实施方式中, 电力网关周期性的主动向主站发送在接收周期 内所存储的多个终端设备的上报数据, 同样可以减少主站与电力网关之间的 建立通信连接的次数以及通信次数, 有利于减少无线网络的通信流量, 有利 于减少无线网络通信资源的浪费。 另外, 该实施方式不需要主站的控制, 有 利于减轻主站的处理负担。
进一步, 电力网关根据所存储的上报数据, 生成第二数据帧, 然后将第 二数据帧发送给主站的过程还可以是: 电力网关接收主站发送的第五数据 帧, 所述第五数据帧的源地址为主站的地址, 目的地址为电力网关的地址。 然后, 电力网关对第五数据帧进行解析, 获取第五数据帧中的获取指令。 所 述获取指令用于指示电力网关将主站需要的上报数据发送给所述主站。 电力 网关在获取到主站的获取指令后, 根据获取指令和存储的上报数据, 生成第 二数据帧, 然后将第二数据帧发送给主站。 在该实施方式中, 电力网关根据 主站的发送的获取指令, 向主站上报接收到的终端设备的上报数据, 允许主 站在需要的时候才与电力网关建立连接, 并通过所建立的连接一次获取多个 终端设备的上报数据, 并且第二数据帧可以包括多个终端设备的上报数据, 而不再像现有技术那样一个数据帧只能包括一个终端设备的一次上报数据, 减少了电力网关与主站之间建立连接的次数以及电力网关与主站之间的通信 次数, 有利于减少无线网络的通信流量, 节约无线网络的通信资源。
其中, 如果电力网关和主站之间使用 DLMS协议进行通信, 则第五数据 帧可以是第五 DLMS帧。
其中, 较为常见的上报数据可以是终端设备根据主站的数据采集指令采 集到的终端设备数据, 例如终端设备采集到的日冻结数据、 月冻结数据等。 上报数据还可以是终端设备主动上报的各种数据, 例如事件告警数据和终端 设备状态数据等。 在本实施例中, 不同事件告警数据的告警等级不同。 事件 告警数据的告警等级可以预先定义, 并且电力网关根据事件告警数据可以获 知事件告警数据的告警等级。 其中, 告警等级越高, 对实时性的要求也就越 高。 在本实施例中, 将告警等级大于或等于预设门限的事件告警数据视为实 时上报数据, 而将告警等级小于预设门限的事件告警数据视为非实时上报数 据。 另外, 其他上报数据, 例如终端设备状态数据, 也属于非实时上报数 据。
10 图 3为本发明另一实施例提供的数据传输方法的流程图。 如图 3所示, 本实施例的方法包括:
步骤 301、 电力网关接收多个终端设备发送的第一 DLMS帧, 每个第一 DLMS帧的源地址为对应的终端设备地址, 目的地址为主站的地址, 每个第 —数据帧的数据部分包含一个终端设备的上报数据。
步骤 302、 电力网关对每个第一 DLMS 帧进行解析, 获取每个第一 DLMS帧中的上报数据。
步骤 303、 电力网关确定每个第一 DLMS帧中的上报数据是否均为非实 时上报数据; 如果确定结果为是, 执行步骤 304; 反之, 执行步骤 306。
步骤 304、 电力网关存储获取的每个第一 DLMS帧中的上报数据。
步骤 305、 电力网关根据所存储的每个第一 DLMS帧中的上报数据, 生 成第二 DLMS帧, 所述第二数据帧的数据部分包含多个上报数据, 并执行步 骤 307。
可选的, 电力网关可以周期性的主动根据每个周期内所存储的上报数 据, 生成第二 DLMS帧, 然后发送给主站。
可选的, 电力网关可以在接收到主站的获取指令后, 根据主站的获取指 令, 根据在获取到获取指令之前所存储的上报数据, 生成第二 DLMS帧, 然 后发送给主站。
具体的, 电力网关可以将所存储的上报数据封装在第二 DLMS帧中的数 据域中, 然后在第二 DLMS帧的源地址中填充电力网关的地址, 目的地址中 填写主站的地址, 从而生成第二 DLMS帧。
步骤 306、 电力网关直接根据获取的实时上报数据, 生成第二 DLMS 帧, 并执行步骤 307。
当电力网关接收到实时上报数据, 例如存在告警等级大于或等于预设门 限的事件告警数据时, 电力网关不存储该实时上报数据, 而是将该实时上报 数据封装在第二 DLMS帧的数据域中, 通过第二 DLMS帧将该实时上报数据 发送给主站。
对于其他非实时上报数据, 电力网关会进行存储, 然后可以在周期到达 时或者接收到主站的获取指令时将所存储的非实时上报数据封装在第二 DLMS帧中发送给主站。
1 1 步骤 307、 电力网关将第二 DLMS帧发送给主站。
如果电力网关与主站之间的连接是断开的, 电力网关可以先与主站建立 连接, 然后通过所建立的连接将第二 DLMS帧发送给主站。
在本实施例中, 电力网关与主站以及终端设备之间使用 DLMS协议进行 通信。 电力网关接收终端设备发送的 DLMS帧, 对终端设备发送的 DLMS帧 进行解析, 从 DLMS帧的数据域中获取终端设备发送的上报数据, 并基于上 报数据的功能确定上报数据是否均为非实时上报数据, 而在接收到实时上报 数据时直接将其封装成 DLMS帧发送给主站, 在接收到实时上报数据时能够 保证实时上报数据的及时上报, 而对于多个非实时上报数据可以通过一次连 接上报给主站, 有利于减少主站与电力网关之间的通信次数和建立通信连接 的次数, 有利于减少无线网络的通信流量, 减少无线网络资源的浪费。
图 4为本发明又一实施例提供的数据传输方法的流程图。 如图 4所示, 本实施例的方法包括:
步骤 401、 电力网关接收主站发送的第三数据帧。
在本实施例中, 第三数据帧的源地址为主站的地址, 目的地址为电力网 关的地址, 所述第三数据帧的数据部分包含多个操作指令。
步骤 402、 电力网关对第三数据帧进行解析, 获取第三数据帧中的多个 操作指令, 并获取每个操作指令对应的终端设备地址。
步骤 403、 电力网关根据每个终端设备地址对应的操作指令, 生成每个 终端设备地址对应的第四数据帧。
在本实施例中, 每个所述第四数据帧对应一个终端设备地址, 每个第四 数据帧的数据部分包含所述终端设备地址所对应的操作指令, 第四数据帧的 源地址为主站的地址, 目的地址为对应的终端设备地址。
步骤 404、 电力网关将每个终端设备地址对应的第四数据帧发送给每个 终端设备地址对应的终端设备。
在本实施例中, 主站可以在一个第三数据帧中同时携带多个操作指令发 送给电力网关。 电力网关对第三数据帧进行解析, 获取第三数据帧中的多个 操作指令, 然后获取每个操作指令对应的终端设备地址, 然后将每个终端设 备地址对应的多个操作指令重新封装成第四数据帧, 并将第四数据帧发送给 相应的终端设备, 从而控制终端设备进行相应操作。 其中, 终端设备接收到
12 第四数据帧后, 会对第四数据帧进行解析, 从中获取多个操作指令, 并会根 据获取的操作指令执行相应操作。
其中, 操作指令用于标识主站对终端设备进行的操作, 例如要求终端设 备进行数据采集、 对终端设备进行参数配置等。
其中, 不同终端设备的终端设备地址不同, 故终端设备地址可以唯一标 识一个终端设备, 故一个终端设备地址对应的操作指令也就是一个终端设备 对应的操作指令。 即电力网关在从第三数据帧中获取多个操作指令, 并获取 每个操作指令对应的终端设备地址之后, 再获取每个终端设备对应的所有操 作指令, 然后将每个终端设备对应的所有对操作指令一起进行封装并发送给 对应的终端设备。
具体地, 当某个第三数据帧中包含的上报数据来自于不同的终端设备 地址或终端设备标识, 以使得电力网关能够对第三数据帧进行解析, 并区分 和识别相应的上报数据来自于哪个终端设备。
在此说明, 每个终端设备地址(或终端设备)对应的第四数据帧可以是 一个, 也可以是多个, 具体视该终端设备地址对应的操作指令的总数据量以 及第四数据帧的长度而定。 如果该终端设备地址对应的所有操作指令的数据 量较小, 可以被封装在一个第四数据帧中, 则该终端设备地址对应的第四数 据帧即为一个, 反之, 则为多个。
可选的, 电力网关可以将解析得到的多个操作指令和获取到的每个操作 指令对应的终端设备地址存储在 RAM或 FLASH中, 但不限于此。
在本实施例中, 电力网关对主站发送的数据帧进行解析, 获取主站对终 端设备进行操作时的多个操作指令, 并获取每个操作指令对应的终端设备地 址, 然后根据获取的多个操作指令和每个操作指令对应的终端设备地址, 将 每个终端设备地址对应的操作指令重新封装成每个终端设备地址对应的数据 帧后, 发送给每个终端设备地址对应的终端设备, 从而实现控制相应终端设 备进行相应操作的目的。 在本实施例中, 由于电力网关具有解析和重新封装 成数据帧的功能, 使得主站可以一次向电力网关发送多个操作指令, 主站不 用在对每个终端设备的每次操作都通过电力网关向终端设备发送操作指令就 可以实现对多个终端设备进行多种操作, 减少了主站与电力网关之间的通信
13 次数, 进而减少了无线网络的通信流量, 降低了对无线网络资源的浪费。 进一步, 主站可以与电力网关预先约定: 如果第三数据帧中不包括操作 指令对应的终端设备地址, 则电力网关获取该电力网关所连接的所有终端设 备的终端设备地址作为该操作指令对应的终端设备地址; 如果第三数据帧中 包括操作指令对应的终端设备地址, 则电力网关可以直接从第三数据帧中获 取该操作指令对应的终端设备地址。
例如, 对于一些主站需要对所有终端设备进行的操作, 主站可以仅在第 三数据帧中携带这些操作对应的操作指令, 而不用携带该些操作指令对应的 终端设备地址, 这有利于提高第三数据帧的利用率。 对于这些操作指令, 电 力网关通过对第三数据帧进行解析, 从中获取这些操作指令; 而对于这些操 作指令对应的终端设备地址, 电力网关可以获取自己所连接的所有终端设备 的地址作为这些操作指令对应的终端设备地址。 其中, 电力网关可以获知其 所有连接的终端设备的信息。
例如, 对于一些主站需要对部分终端设备进行的操作, 为了明确这些操 作是对哪些终端设备进行的, 主站需要在第三数据帧中同时携带这些操作对 应的操作指令和这些操作指令对应的终端设备地址。 对于这些操作指令及对 应的终端设备地址, 电力网关通过对第三数据帧进行解析, 从中获取这些操 作指令和各操作指令对应的终端设备地址。
在终端设备监测系统中, 所处理的数据为非实时数据, 因此, 主站控制 终端设备进行操作的操作指令也多为非实时操作指令, 但不限于此。 即主站 控制终端设备进行操作的操作指令还可能是实时操作指令。 其中, 较为常见 的非实时操作指令包括数据采集指令和参数配置指令。 其中, 数据采集指令 用于控制终端设备进行非实时数据的采集, 例如采集日冻结数据、 月冻结数 据等。 参数配置指令主要用于控制终端设备进行参数配置。 其中, 操作指令 是实时操作指令还是非实时操作指令, 可以根据操作指令的功能预先配置。
较为优选的, 本实施例仅对非实时操作指令进行处理, 即本实施例的操 作指令优选为非实时操作指令, 但不限于此。
基于上述, 电力网关在获取第三数据帧中的多个操作指令并获取每个操 作指令对应的终端设备地址之后, 可以根据每个操作指令的功能, 确定每个 操作指令是否均为非实时操作指令。 如果确定结果为每个操作指令均为非实 时操作指令, 则电力网关可以存储每个操作指令和每个操作指令对应的终端 设备地址。 如果确定结果为多个操作指令中存在实时操作指令, 即不是所有 解析获取到的操作指令都是非实时操作指令, 则对于解析到的实时操作指 令, 电力网关可以不存储而直接将该实时指令封装在第四数据帧中, 发送给 对应的终端设备, 以保证对该终端设备的实时操作; 对于非实时操作指令及 对应的终端设备地址, 电力网关可以进行存储。 电力网关通过判断解析获取 到的操作指令是否均为非实时操作指令, 在有实时操作指令存在时直接将实 时操作指令封装成数据帧转发给终端设备, 有利于保证实时操作指令被及时 发送给终端设备, 保证对终端设备操作的实时性。
进一步, 电力网关接收到第三数据帧之后, 可以断开与主站之间的连 接。 在本实施例中, 电力网关在获取并存储主站发送的多个操作指令后, 会 的操作指令生成新的数据帧, 将新生成的数据帧发送给对应的终端设备去控 故电力网关可以断开与主站之间的连接, 节约主站与电力网关之间保持连接 产生的无线网络通信流量, 进一步减少无线网络通信资源的浪费。
其中, 如果主站和电力网关以及电力网关和终端设备之间采用 DLMS协 议进行通信, 则第三数据帧为第三 DLMS帧, 第四数据帧为第四 DLMS帧。 主站和电力网关以及电力网关和终端设备之间采用的通信协议并不限于 DLMS协议。
其中, 第三 DLMS帧或第四 DLMS帧的结构也如图 2B所示, 主要包 括: 帧头、 目的地址、 源地址、 控制域、 数据域、 校验、 帧结束。
其中, 第三 DLMS帧的源地址为主站的地址, 目的地址为电力网关的地 址。 电力网关根据第三 DLMS帧中的目的地址确定出第三 DLMS帧是发送给 自己的, 进而对第三 DLMS帧进行解析, 获取第三 DLMS帧中的多个操作指 令, 或者获取第三 DLMS帧中的多个操作指令和每个操作指令对应的终端设 备地址。 其中, 多个操作指令或操作指令和其对应的终端设备地址封装在第 三 DLMS帧的数据域中。
其中, 第四 DLMS帧的源地址为主站的地址, 目的地址为相应的终端设 备地址。 由于电力网关对各个终端设备来说是透明的, 故电力网关在重新将
15 操作指令封装成 DLMS帧时, 通过封装成源地址为主站、 目的地址为相应终 端设备地址的 DLMS帧, 这样可以不用对终端设备进行改动, 有利于实现对 现有终端设备的兼容。
下面将以主站和电力网关以及电力网关和终端设备之间采用 DLMS协议 进行通信为例, 详细说明本发明提供的数据传输方法的流程。
图 5为本发明又一实施例提供的数据传输方法的流程图。 如图 5所示, 本实施例的方法包括:
步骤 501、 电力网关接收主站发送的第三 DLMS帧。
其中, 所述第三 DLMS帧的数据部分包含多个操作指令, 第三 DLMS帧 的源地址为主站的地址, 目的地址为电力网关的地址。
步骤 502、 电力网关对第三 DLMS帧进行解析, 获取多个操作指令, 并 获取每个操作指令对应的终端设备地址。
其中, 如果第三 DLMS帧不包括操作指令对应的终端设备地址, 则电力 网关获取其所连接的所有终端设备的终端设备地址作为操作指令对应的终端 设备地址。
如果第三 DLMS帧包括操作指令对应的终端设备地址, 则电力网关从第 三 DLMS帧中获取操作指令对应的终端设备地址。
步骤 503、 电力网关存储获取的多个操作指令和每个操作指令对应的终 端设备地址。
本实施例以操作指令均为非实时操作指令为例进行说明。
步骤 504、 电力网关根据每个终端设备地址对应的操作指令, 生成每个 终端设备地址对应的第四 DLMS帧。
其中, 每个所述第四 DLMS帧对应一个终端设备地址, 每个第四数据帧 的数据部分包含所述终端设备地址所对应的操作指令第四 DLMS帧的源地址 为主站的地址, 目的地址为对应的终端设备地址。
步骤 505、 电力网关将每个终端设备地址对应的第四 DLMS帧发送给每 个终端设备地址对应的终端设备, 以控制每个终端设备地址对应的终端设备 进行相应操作。
其中, 在电力行业, 主站与终端设备之间的数据多为非实时数据, 即多 数数据对实时性的要求较低。 例如, 日冻结、 月冻结的数据都不要求实时获
16 取。
基于此, 在本实施例中, 主站可以将要对终端设备进行的多个操作指令 封装在第三 DLMS帧中, 然后发送给电力网关。 而电力网关接收主站发送的 第三 DLMS帧, 并对接收到的第三 DLMS帧进行解析, 获取第三 DLMS帧 中的多个操作指令, 并获取每个操作指令的终端设备地址, 然后将获取的多 个操作指令和每个操作指令对应的终端设备地址存储起来。 例如, 电力网关 可以将获取的多个操作指令和每个操作指令对应的终端设备地址存储在 RAM或 FLASH中 , 但不限于此。
然后, 由电力网关根据存储的多个操作指令和每个操作指令对应的终端 设备地址, 控制每个终端设备地址对应的终端设备进行相应操作。 其中, 每 个终端设备地址可能对应一个操作指令, 也可能同时对应多个操作指令。 其 中, 电力网关控制每个终端设备地址对应的终端设备进行相应操作主要是依 次将每个终端设备地址的对应的操作指令封装成第四 DLMS帧发送给对应的 终端设备的过程。 在这个过程中, 而不需要主站参与, 主站只需将多个操作 指令一次发送给点电力网关即可, 而不再像现有技术那样主站对每个终端设 备的每次操作都要通过电力网关向终端设备发送操作指令, 有利于减少电力 网关与主站之间的通信次数, 进而减少了无线网络的通信流量, 减少了无线 网络通信资源的浪费。
进一步, 在电力网关与主站的一次连接过程中, 电力网关可以接收主站 发送的多个第三 DLMS帧, 并获取每个第三 DLMS帧中的多个操作指令, 同 样获取每个操作指令对应的终端设备地址, 并可选的将获取的操作指令和对 应的终端设备地址都存储起来。 这样有利于减少电力网关与主站之间建立通 信连接的次数, 进一步可以减少无线网络资源的浪费。 之后, 电力网关根据 每个终端设备地址对应的操作指令, 生成每个终端设备地址对应的第四 DLMS帧, 即电力网关将每个终端设备地址对应的操作指令封装在一个或多 个第四 DLMS帧的数据域中, 然后发送给对应的终端设备。 在本实施例中, 一个第四 DLMS帧中可以同时封装多个操作指令, 而不同于现有技术中一个 DLMS帧仅封装一个终端设备的一个操作指令。 这样可以减少电力网关与终 端设备之间的通信次数, 有利于节约局域网资源。
在本实施例中, 电力网关对主站的 DLMS帧进行解析, 获取操作指令和
17 操作指令对应的终端设备地址, 然后基于获取的操作指令和操作指令对应的 终端设备地址控制相应终端设备进行相应操作, 使得主站仅需向电力网关发 送多个操作指令并提供每个操作对应的终端设备地址即可, 而不用每次都通 过电力网关向每个终端设备分别发送操作指令, 减少了主站与电力网关之间 的通信次数, 进而减少了无线网络的通信流量, 降低了对无线网络资源的浪 费。
图 6为本发明又一实施例提供的数据传输方法的流程图。 如图 6所示, 本实施例的方法包括:
步骤 601、 电力网关接收主站发送的第三 DLMS帧, 所述第三 DLMS帧 的数据部分包含多个操作指令第三 DLMS帧的源地址为主站的地址, 目的地 址为电力网关的地址。
步骤 602、 电力网关对第三 DLMS帧进行解析, 从第三 DLMS帧中获取 多个操作指令, 并获取每个操作指令对应的终端设备地址。
步骤 603、 电力网关根据每个操作指令的功能, 确定每个操作指令是否 均为非实时操作指令; 如果确定结果为是, 则执行步骤 604; 如果确定结果 为否, 执行步骤 606。
其中, 每个操作指令的功能是预先定义好的, 并且电力网关和主站根据 操作指令均可以获知该操作指令的功能。 另外, 操作指令是实时操作指令还 是非实时操作指令, 也是预先根据操作指令的功能确定好的, 并且电力网关 和主站根据操作指令的功能可以确定该操作指令是实时操作指令还是非实时 操作指令。
具体的, 主站和电力网关上可以预先存储有一个映射表, 该映射表中存 储有操作指令、 操作指令的功能以及操作指令是否为非实时操作指令之间的 对应关系。
步骤 604、 电力网关存储每个操作指令和每个操作指令对应的终端设备 地址。
由于是非实时操作指令, 故可以将其存储下来, 然后将一段时间内对同 一终端设备进行操作的多个操作指令一次发送给该终端设备, 有利于减少电 力网关和终端设备之间的通信次数, 有利于节约局域网资源。
步骤 605、 电力网关根据存储的每个终端设备地址对应的操作指令, 生 成每个终端设备地址对应的第四 DLMS帧, 每个所述第四数据帧对应一个终 端设备地址, 每个第四数据帧的数据部分包含所述终端设备地址所对应的操 作指令并执行步骤 607。
步骤 606、 电力网关直接根据实时操作指令, 生成该实时操作指令对应 的第四 DLMS帧, 并执行步骤 607。
其中, 步骤 606所描述的对实时操作指令的处理方式仅为一种可选实施 方式, 并不限于此。 址存储起来, 而不是实时转发。
步骤 607、 电力网关将第四 DLMS帧发送给对应的终端设备, 以控制该 终端设备进行相应操作。
在本实施例中, 电力网关根据每个操作指令的功能, 确定每个操作指令 是否均为非实时操作指令, 即确定多个操作指令是否全部不需要立即转发给 终端设备; 如果确定结果为是, 说明该主站对终端设备的该多种操作均不是 实时的, 故电力网关可以将每个操作指令和每个操作指令对应的终端设备地 址存储起来, 以便后续将一段时间内存储的操作指令一次性发送给对应的终 端设备以控制终端设备进行相应操作; 如果确定结果为否, 说明该主站对终 端设备的多种操作中存在需要实时处理的操作, 则为了保证对终端设备操作 的实时性, 电力网关可以不对实时操作指令进行存储, 而是直接根据实时操 作指令生成第四 DLMS帧, 然后发送给相应终端设备, 以控制相应终端设备 进行相应操作。
其中, 终端设备接收到电力网关发送的第四 DLMS帧后, 会根据 DLMS 帧的格式, 对第四 DLMS 帧进行解析, 获取其中的操作指令并进行相应操 作。
在本实施例中, 电力网关在存储多个操作指令之前, 首先根据每个操作 指令的功能确定操作指令是否均为非实时操作指令, 对于非实时操作指令进 行存储, 而对于存在实时操作指令的情况不进行存储, 有利于保证对终端设 备操作的实时性。
但是, 在此说明, 对于实时操作指令也可以进行存储。
图 7为本发明又一实施例提供的数据传输方法的流程图。 如图 7所示,
19 本实施例的方法包括:
步骤 701、 主站生成第三数据帧, 所述第三数据帧包括多个操作指令。 在本实施例中, 第三数据帧的源地址为主站的地址, 目的地址为电力网 关的地址。
步骤 702、 主站将第三数据帧发送给电力网关, 以使所述电力网关根据 所述多个操作指令生成第四数据帧, 每个所述第四数据帧对应一个终端设备 地址, 每个第四数据帧的数据部分包含所述终端设备地址所对应的操作指 令, 并使所述电力网关将所述第四数据帧发送给其对应的终端设备。
在本实施例中, 为了使电力网关识别数据帧是发送给自己的而不是发送 给终端设备的, 主站将第三数据帧的目的地址填充为电力网关的地址, 使得 电力网关不再像现有技术那样直接透传主站的数据帧给终端设备。
在本实施例中, 主站与电力网关相配合, 基于电力网关具有解析第三数 据帧, 从中获取操作指令, 并会自行获取操作指令对应的终端设备地址, 然 后根据每个终端设备地址对应的操作指令生成第四数据帧并将第四数据帧发 送给对应的终端设备以控制终端设备进行相应操作的功能, 主站只需通过第 三数据帧同时向电力网关发送多个操作指令, 而不用在对每个终端设备的每 次操作都要通过电力网关向每个终端设备分别发送操作指令, 减少了与电力 网关之间的通信次数, 减少了无线网络的通信流量, 节约了无线网络的通信 资源。
进一步, 主站可以在第三数据帧中同时携带操作指令和操作指令对应的 终端设备地址。 基于此, 电力网关可以直接从第三数据帧中解析出多个操作 指令和每个操作指令对应的终端设备地址。
另外, 主站也可以仅在第三数据帧中携带操作指令, 则电力网关可以从 电数据帧中解析出操作指令, 而对于操作指令对应的终端设备地址, 电力网 关可以获取自己所连接的所有终端设备的地址作为该操作指令对应的终端设 备地址。
进一步, 主站将第三数据帧发送给电力网关之后, 还可以断开与电力网 关之间的连接。 由于主站一次性将多个操作指令发送给了电力网关, 在一段 时间内可能不需要在向电力网关发送操作指令, 并且由于电力网关根据获取 的操作指令和操作指令对应的终端设备地址控制相应终端设备执行相应操作
20 的过程可长可短, 故主站在将第三数据帧发送给电力网关之后断开与电力网 挂之间的连接, 有利于节约主站保持与电力网关之间的连接所产生的无线网 络通信流量, 进一步可以减少无线网络资源的浪费。
更进一步, 主站可以确定每个操作指令是否均为非实时操作指令; 如果 确定结果为每个操作指令均为非实时操作指令, 则主站执行断开与电力网关 之间的连接的操作。 如果确定结果为并不是每个操作指令均为非实时操作指 令, 则主站可以继续保持与电力网关之间的连接, 以便于能够及时获取终端 设备根据实时操作指令返回的操作响应数据。 主站通过判断发送给电力网关 的操作指令是否均为非实时操作指令, 在存在实时操作指令时, 便于获取终 端设备返回的实时操作响应, 有利于保证实时操作指令的执行。
更进一步, 主站还可以向电力网关发送第五数据帧, 该第五数据帧的源 地址为主站的地址, 目的地址为电力网关的地址, 该第五数据帧包括获取指 令, 该获取指令用于指示电力网关将所存储的多个终端设备发送的上报数据 发送给主站。 其中, 所述上报数据可以是终端设备根据主站的操作指令进行 相应操作返回的操作响应数据, 也可以是终端设备主动上报的各种数据, 例 如事件告警数据、 终端设备状态数据等。
在本实施例中, 非实时操作指令可以是数据采集指令或参数配置指令, 但不限于此。
其中, 主站和电力网关之间的通信协议可以是 DLMS 协议, 但不限于 此。 例如主站和电力网关之间还可以采用 Q / GDW 376.1-2009协议进行通 信。
其中, 如果主站和电力网关使用 DLMS协议进行通信, 则第三数据帧为 第三 DLMS帧。 相应的, 第五数据帧可以是第五 DLMS帧。
图 8为本发明又一实施例提供的数据传输方法的流程图。 如图 8所示, 本实施例的数据传输方法包括:
步骤 801、 主站生成第三 DLMS帧, 所述第三 DLMS帧的源地址为主站 的地址, 目的地址为电力网关的地址。
步骤 802、 主站将第三 DLMS帧发送给电力网关, 然后断开与电力网关 之间的连接。
可选的, 主站可以根据每个操作指令的功能, 确定每个操作指令是否均 为非实时操作指令; 如果确定结果为每个操作指令均为非实时操作指令, 则 执行断开与电力网关之间的连接的操作。
步骤 803、 电力网关解析第三 DLMS帧, 获取并存储第三 DLMS帧中的 多个操作指令和每个操作指令对应的终端设备地址。
本实施例以第三 DLMS帧同时包括操作指令和操作指令对应的终端设备 地址为例进行说明。
例如, 假设第三 DLMS帧包括三个操作指令, 分别为第三操作指令、 第 四操作指令和第三操作指令, 且第三操作指令对应第三终端设备地址、 第四 终端设备地址和第三终端设备地址, 第四操作指令对应第三终端设备地址, 第三操作指令对应第三终端设备地址和第四终端设备地址。
可选的, 电力网关可以根据每个操作指令的功能, 确定每个操作指令是 否均为非实时操作指令; 如果确定结果为是, 则执行存储每个操作指令和每 个操作指令对应的终端设备地址的操作。 生成每个终端设备地址对应的第四 DLMS帧。
其中, 每个终端设备地址对应的第四 DLMS帧可以是一个, 也可以是多 个。 每个第四 DLMS帧中可以同时包括多个操作指令。
步骤 805、 电力网关将每个终端设备地址对应的第四 DLMS帧发送给每 个终端设备地址对应的终端设备, 以控制每个终端设备地址对应的终端设备 进行相应操作。
在本实施例中 , 主站和电力网关相配合, 主站通过一个 DLMS帧将多个 操作指令和每个操作指令对应的终端设备地址发送给电力网关, 电力网关解 析主站发送的 DLMS帧并存储获取的操作指令和对应的操作地址, 根据存储 的操作指令和对应的操作地址控制相应终端设备进行相应操作, 有利于减少 主站与电力网关之间的通信次数, 进而减少了无线网络的通信流量, 降低了 对无线网络资源的浪费。
图 9为本发明又一实施例提供的数据传输方法的流程图。 如图 9所示, 本实施例的方法包括:
步骤 901、 主站生成第三 DLMS帧, 第三 DLMS帧包括数据采集指令、 参数配置指令以及数据采集指令和参数配置指令分别对应的终端设备地址。
22 步骤 902、 主站将第三 DLMS帧发送给电力网关, 并在发送第三 DLMS 帧后断开与电力网关之间的连接。
在本实施例中, 以主站对终端设备的操作指令为数据采集指令和参数配 置指令为例进行说明, 但不限于此。 其中, 其他操作指令的处理流程可以参 考本实施例的流程。 例如, 所要配置的参数可以是日冻结时间、 月冻结时 间、 费率以及分析时段等参数。
具体的, 主站按照 DLMS帧的格式, 将采集终端设备数据的数据采集指 令和对终端设备进行参数配置的参数配置指令, 以及数据采集指令和参数配 置指令分别对应的终端设备地址封装在第三 DLMS帧的数据域中, 并在目的 地址字段中填写电力网关的地址, 在源地址字段中填写主站地址, 以及在其 他字段中填写相应数据后生成第三 DLMS帧。 然后, 主站将第三 DLMS帧发 送给电力网关。 具体来说, 是主站通过其 DLMS客户端将第三 DLMS帧发送 给电力网关的 DLMS服务器。
在本实施例中, 由于数据采集指令和参数配置指令均为非实时操作指 令, 因此, 既不需要终端设备根据操作指令进行实时操作, 也不需要终端设 备实时返回操作结果, 故主站在将第三 DLMS帧发送给电力网关之后, 断开 与电力网关之间的连接, 有利于节约无线网络的通信流量, 提高无线网络资 源的利用率。
步骤 903、 电力网关对接收到的第三 DLMS帧进行解析, 获取并存储第 三 DLMS帧中的数据采集指令、 参数配置指令以及数据采集指令和参数配置 指令分别对应的终端设备地址。
具体的, 电力网关按照 DLMS帧的格式, 对第三 DLMS帧进行解析, 根 据第三 DLMS帧的目的地址为电力网关的地址识别出该第三 DLMS帧是发送 给自己的, 而不是发送给终端设备的, 故电力网关从第三 DLMS帧中的数据 域中获取数据采集指令、 参数配置指令以及数据采集指令和参数配置指令分 别对应的终端设备地址。 其中, 在终端设备监测系统中, 每个终端设备对应 唯一的一个地址, 即终端设备地址, 故本发明各实施例通过终端设备地址唯 一标识某个终端设备。 在本实施例中, 终端设备地址用于标识数据采集指令 或参数配置指令对应的终端设备。
其中, 终端设备地址可以是终端设备的介质访问控制 (Media Access
23 Control, MAC )地址, 但不限于此。
在本实施例中, 主站对终端设备进行数据采集的操作属于非实时操作, 主站对终端设备进行参数配置的操作也属于非实时操作, 即对实时性要求较 低, 故相应的数据采集指令和参数配置指令也不需要终端设备实时执行。 因 此, 本实施例的电力网关根据数据采集指令的功能(即采集终端设备数据) 和参数配置指令的功能(即配置终端设备的参数) , 可以确定出数据采集指 令和参数配置指令均为非实时指令。 故电力网关将获取的数据采集指令、 参 数配置指令以及数据采集指令和参数配置指令分别对应的终端设备地址进行 存储。 例如, 电力网关可以将数据采集指令和终端设备地址存储在 RAM或 FLASH中, 但不限于此。 生成每个终端设备地址对应的第四 DLMS帧, 所述第四 DLMS帧包括数据采 集指令和 /或参数配置指令。
在本实施例中, 电力网关将每个终端设备地址对应的操作指令封装在第 四 DLMS帧的数据域中, 并在源地址字段中填充主站的地址, 在目的地址字 段中填充相应终端设备地址, 在其他字段中填充相应数据后形成第四 DLMS 帧。
其中, 每个终端设备地址对应的操作指令可以是数据采集指令和参数配 置指令中至少其中之一, 并且不同终端设备地址对应的操作指令可以相同, 也可以不同。
步骤 905、 电力网关将每个终端设备地址对应的第四 DLMS帧发送给每 个终端设备地址对应的终端设备, 以控制终端设备执行相应操作。
在本实施例中, 电力网关通过将每个终端设备对应的操作指令封装成 DLMS帧并发送给相应的终端设备达到控制相应终端设备执行相应操作的目 的。 其中, 电力网关可以依次将每个终端设备对应的第四 DLMS帧发送给每 个终端设备。
步骤 906、 多个终端设备分别根据接收到的操作指令执行相应操作, 并 向电力网关发送第一 DLMS帧。
在本实施例中, 每个终端设备接收到第四 DLMS帧后, 根据 DLMS帧的 结构对第四 DLMS帧进行解析, 从第四 DLMS帧的数据域中获取操作指令,
24 然后根据获取的操作指令执行相应操作。 例如, 如果获取的操作指令为数据 采集指令, 则终端设备根据数据采集指令进行数据采集; 如果获取的操作指 令为参数配置指令, 则终端设备根据参数配置指令进行有关参数的配置; 如 果获取的操作指令同时包括数据采集指令和参数配置指令, 则终端设备会根 据数据采集指令和参数配置指令分别进行数据采集和参数配置。
在本实施例中, 当终端设备执行完相应操作之后, 会将操作结果, 例如 采集到的数据和 /或参数配置完成响应, 封装在第一 DLMS 帧的数据域中, 并在第一 DLMS帧的源地址字段填充终端设备地址, 在目的地址字段填充主 站的地址, 并对其他字段进行相应填充后发送给电力网关。
在本实施例中, 终端设备的操作结果为终端设备需要上报给主站的上报 数据中的一种。
可选的, 在实施例中, 如果终端设备有数据需要主动上报给主站, 则终 端设备还可以在第一 DLMS帧中封装主动上报数据。 其中, 主动上报数据可 以是事件告警数据或终端设备状态数据等, 但不限于此。 主动上报数据也是 终端设备需要上报给主站的上报数据中的一种。
步骤 907、 电力网关接收多个终端设备分别发送的第一 DLMS帧, 对第 一 DLMS帧进行解析, 获取并存储第一 DLMS帧中的上报数据。
在本实施例中, 电力网关根据 DLMS帧的格式, 对每个第一 DLMS帧进 行解析, 根据第一 DLMS帧的目的地址识别出该第一 DLMS帧是终端设备要 发送给主站的, 故从第一 DLMS帧的数据域中获取终端设备的上报数据并存 储, 而不再像现有技术那样直接将第一 DLMS帧转发给主站。
可选的, 电力网关在获取到第一 DLMS帧中的上报数据后, 可以根据上 报数据的功能确定上报数据是否为非实时上报数据, 并在所有第一 DLMS帧 中的上报数据均为非实时上报数据时, 将获取的上报数据进行存储。
例如, 如果第一 DLMS帧中的上报数据为终端设备根据操作指令进行相 应操作后返回的操作结果, 则电力网关可以直接确定该上报数据为非实时上 报数据。 如果第一 DLMS帧中的上报数据除了包括终端设备返回的操作结果 还包括终端设备主动上报的事件告警数据, 则电力网关还需要根据事件告警 数据的告警等级确定该事件告警数据是否为非实时上报数据, 例如如果事件 告警数据的告警等级小于预设门限, 则确定该事件告警数据为非实时上报数
25 据, 反之, 确定该事件告警数据为实时上报数据。
当所有上报数据均为非实时上报数据时, 电力网关存储获取到的各终端 设备的上报数据并对应存储相应的终端设备地址。 址等存储在 RAM或 FLASH中, 但不限于此。
步骤 908、 主站与电力网关建立连接。
步骤 909、 电力网关接收主站发送的第五 DLMS帧, 第五 DLMS帧的源 地址为主站的地址, 目的地址为电力网关的地址。
在本实施例中, 当主站需要获取终端设备的上报数据时, 首先与电力网 关建立连接, 然后通过所建立的连接向电力网关发送获取指令。 其中, 该获 取指令被封装在第五 DLMS帧的数据域中发送给电力网关。
步骤 910、 电力网关对第五 DLMS帧进行解析, 获取第五 DLMS帧中的 获取指令。
步骤 911、 电力网关根据获取的获取指令, 将所存储的多个终端设备的 上报数据封装在第二 DLMS帧中的数据域中, 通过第二 DLMS帧发送给主 站。
在本实施例中, 电力网关会将多个终端设备的上报数据以及对应的终端 设备地址封装在第二 DLMS帧的数据域中。 如果一个第二 DLMS帧的数据域 无法封装完所有终端设备的上 4艮数据, 电力网关可以通过两个、 三个等多个 第二 DLMS 帧来封装所有终端设备的上报数据。 在此说明, 由于本实施例 中, 只有在当前第二 DLMS帧的数据域没有剩余空间, 而上报数据还有剩余 的情况下才会生成下一个第二 DLMS帧, 因此本实施例第二 DLMS帧的个数 小于上报数据的个数, 即本实施例电力网关发送给主站的第二 DLMS帧的个 数小于现有技术中电力网关向主站转发上报数据使用的 DLMS帧的个数。 例 如, 假设 3个终端设备共上报了 6个上报数据, 则本实施例可以使用小于 6 个的第二 DLMS帧将这 6个上报数据发送给主站, 而现有技术就需要 6个 DLMS帧分别将这 6个上报数据发送给主站。
在本实施例中, 电力网关在第二 DLMS帧的源地址字段中填充电力网关 的地址, 在目的地址字段中填充主站的地址。
在本实施例中, 由于电力网关可以对主站和终端设备发送的 DLMS帧进
26 行解析, 并具有从 DLMS帧中获取的操作指令并会主动获取的每个操作指令 对应的终端设备地址以及根据获取的操作指令和对应的终端设备地址去控制 相应终端设备执行相应操作的功能, 使得主站可以一次向电力网关发送多个 操作指令, 而不像现有技术那样主站通过电力网关对每个终端设备的每次操 作进行控制, 减少了主站与电力网关之间的通信次数, 减少了无线网络的通 信流量, 减少了无线网络资源的浪费, 并且通过断开与电力网关之间的连接 提高了无线网络资源的利用率; 另外, 电力网关通过对终端设备上报数据进 行存储, 通过在一次连接中将多个终端设备的上报数据同时发送给主站, 有 利于减少主站与电力网关之间建立连接的次数以及通信次数, 同样有利于减 少无线网络的通信流量, 减少无线网络资源的浪费。
在此说明, 上述各实施例中涉及的第一 DLMS帧、 第二 DLMS帧、 第三 DLMS帧、 第四 DLMS帧以及第五 DLMS帧均为 DLMS帧, 其区别在于数 据域以及源地址、 目的地址的内容有所不同。
图 10A为本发明一实施例提供的电力网关的结构示意图。 如图 10A所 示, 本实施例的电力网关包括: 第一接收器 1001、 第一处理器 1002、 第一 存储器 1003和第一发送器 1004。

本实施例的电力网关, 具有解析终端设备发送的第一数据帧并存储获取
27 的上报数据的功能, 电力网关不用再像现有技术那样每接收一个终端设备的 一个第一数据帧就要与主站建立连接并通过建立的连接转发给主站, 而是可 以存储多个终端设备的上报数据, 然后在与主站的一次连接过程中发送给主 站, 减少了与主站之间建立连接的次数, 进而减少了无线网络的通信流量, 减少了无线网络通信资源的浪费。
在上述实施例中, 电力网关和终端设备之间以及电力网关和主站之间可 以采用 DLMS协议进行通信, 但不限于此。 例如, 电力网关还可以使用 Q / GDW 376.1-2009协议与主站进行通信, 而使用 Q / GDW 376.2-2009协议与 终端设备进行通信。
当电力网关和终端设备之间以及电力网关和主站之间可以采用 DLMS协 议进行通信时, 第一数据帧可以是第一 DLMS 帧, 第二数据帧可以是第二 DLMS数据帧。
进一步, 如图 10B所示, 本实施例电力网关的第一处理器 1002还包括确 定单元 10023。 确定单元 10023用于确定每个上报数据是否均为非实时上报 数据。 具体的, 确定单元 10023可以根据每个上报数据的功能或者数据帧包 含的数据类型标识, 确定每个上报数据是否均为非实时上报数据。
基于此, 第一存储器 1003还与确定单元 10023连接, 具体用于在确定单 元 10023确定出上报数据均为非实时上报数据时, 存储上报数据。
第一发送器 1004 具体用于建立到主站的连接, 然后通过所建立的连接 将第二数据帧发送给主站。

28 图 11A为本发明又一实施例提供的电力网关的结构示意图。 如图 11A所 示, 本实施例的电力网关包括: 第二接收器 1111、 第二处理器 1112和第二 发送器 1113。
其中, 第二接收器 1111 , 用于接收主站发送的第三数据帧, 所述第三数 据帧的数据部分包含多个操作指令。
第二处理器 1112包括第二解析单元 11121和第二生成单元 11122。 第二 解析单元 11121 , 与第二接收器 1111连接, 用于对第二接收器 1111接收到 的第三数据帧进行解析, 获取第三数据帧中的多个操作指令, 并获取每个操 作指令对应的终端设备地址。 第二生成单元 11122, 与第二解析单元 11121 连接, 用于根据每个终端设备地址对应的操作指令, 生成每个终端设备地址 对应的第四数据帧, 每个所述第四数据帧对应一个终端设备地址, 每个第四 数据帧的数据部分包含所述终端设备地址所对应的操作指令。

本实施例电力网关的各功能单元可用于执行图 4所示数据传输方法的流 程, 其具体工作原理不再赘述, 详见方法实施例的描述。
本实施例的电力网关, 对主站发送的数据帧进行解析, 获取主站对终端 设备进行操作时的多个操作指令, 并获取每个操作指令对应的终端设备地 址, 然后根据获取的多个操作指令和每个操作指令对应的终端设备地址, 将 每个终端设备地址对应的操作指令重新封装成每个终端设备地址对应的数据 帧后, 发送给每个终端设备地址对应的终端设备, 从而实现控制相应终端设 备进行相应操作的目的。 由于本实施例的电力网关具有解析和重新封装成数 据帧的功能, 使得主站可以一次向电力网关发送多个操作指令, 主站不用在 对每个终端设备的每次操作都通过电力网关向终端设备发送操作指令就可以 实现对多个终端设备进行多种操作, 减少了主站与电力网关之间的通信次 数, 进而减少了无线网络的通信流量, 降低了对无线网络资源的浪费。
在上述实施例中, 电力网关和终端设备之间以及电力网关和主站之间可 以采用 DLMS协议进行通信, 但不限于此。 例如, 电力网关还可以使用 Q / GDW 376.1-2009协议与主站进行通信, 而使用 Q / GDW 376.2-2009协议与
29 终端设备进行通信。
当电力网关和终端设备之间以及电力网关和主站之间可以采用 DLMS协 议进行通信时, 第三数据帧可以是第三 DLMS 帧, 第四数据帧可以是第四 DLMS数据帧。
本实施例电力网关的第二解析单元 11121具体可以用于在第三数据帧不 包括所述操作指令对应的终端设备地址, 获取电力网关所连接的所有终端设 备的终端设备地址作为操作指令对应的终端设备地址; 在第三数据帧包括操 作指令对应的终端设备地址, 从第三数据帧中获取操作指令对应的终端设备 地址。
进一步, 如图 11B所示, 本实施例的第二处理器 1112还包括: 第一连接 控制单元 11123。 第一连接控制单元 11123用于在第二接收器 1111接收到第 三数据帧后, 断开与主站之间的连接。 由于本实施例的电力网关在获取并存 储主站发送的多个操作指令后, 会自行获取每个操作指令对应的终端设备地 址并会根据每个终端设备地址对应的操作指令生成新的数据帧, 将新生成的 数据帧发送给对应的终端设备去控制每个终端设备地址对应的终端设备进行 相应操作, 而不需要主站的参与, 故电力网关可以断开与主站之间的连接, 节约主站与电力网关之间保持连接产生的无线网络通信流量, 进一步减少无 线网络通信资源的浪费。
图 12为本发明一实施例提供的主站的结构示意图。 如图 12所示, 本实 施例的主站包括: 第三处理器 1211和第三发送器 1212。

本实施例主站的各功能单元可用于执行图 7所示数据传输方法的流程, 其具体工作原理不再赘述, 详见方法实施例的描述。
30 本实施例的主站, 与图 11A或图 11B所示实施例提供的电力网关相配 合, 基于电力网关具有解析第三数据帧从中获取操作指令, 并获取操作指令 对应的终端设备地址, 并会根据获取的操作指令和对应的终端设备地址控制 相应终端设备执行相应操作的功能, 使得主站只需一次向电力网关发送多个 作指令, 减少了与电力网关之间的通信次数, 减少了无线网络的通信流量, 节约了无线网络的通信资源。
在上述实施例中, 主站和电力网关之间可以采用 DLMS协议进行通信, 但不限于此。 例如, 主站还可以使用 Q / GDW 376.1-2009协议与电力网关进 行通信。
当主站和电力网关之间采用 DLMS协议进行通信时, 第三数据帧可以是 第三 DLMS帧。
进一步, 如图 12 所示, 第三处理器 1211 还包括第二连接控制单元 12112。 第二连接控制单元 12112用于在第三发送器 1212将第三数据帧发送 给电力网关之后, 断开与电力网关之间的连接, 以进一步减少无线网络的通 信流量, 减少无线网络资源的浪费, 提高无线网络资源的利用率。
更进一步, 第二连接控制单元 12112具体可以用于确定每个操作指令是 否均为非实时操作指令, 在确定结果为操作指令均为非实时操作指令时, 断 开与电力网关之间的连接的操作。 本实施例的第二连接控制单元 12112通过 判断操作指令是否均为非实时操作指令, 并在操作指令均为非实时操作指令 时, 才在发送第三数据帧后断开与电力网关的连接, 而在存在实时操作指令 的情况下可以保持与电力网关之间的连接, 可以保证及时获取终端设备执行 实时操作返回的结果, 有利于实时操作指令的执行。
更进一步, 本实施例的第三发送器 1212还可以用于向电力网关发送第 五数据帧, 所述第五数据帧的源地址为主站的地址, 目的地址为电力网关的 地址, 所述第五数据帧包括获取指令, 所述获取指令用于指示电力网关将主 站需要的上报数据发送给主站。
其中, 终端设备发送的上报数据可以是终端设备执行操作指令返回的操 作结果, 也可以是终端设备主动上报的数据, 例如终端设备状态数据或事件 告警数据等。
31 本实施例的第三发送器 1212 通过向电力网关发送获取指令, 实现了在 需要获取上报数据的时候才获取上报数据, 而不再像现有技术那样只要有上 报数据就转发给主站, 减少了主站与电力网关之间建立通信连接的次数以及 通信次数, 有利于减少无线网络的通信流量, 减少无线网络资源的浪费。
