为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

本发明实施例提供了一种分配通信地址的***，包括主站，DCU和若干智能仪表，如图3所示，为本发明实施例的***框架示意图。每个智能仪表可以具有唯一的标识符(如表号),某个地区(如某小区)内所有的用户的智能仪表接入该地区的DCU中，DCU与主站通信。The embodiment of the present invention provides a system for allocating a communication address, including a primary station, a DCU, and a plurality of smart meters. As shown in FIG. 3, it is a schematic diagram of a system framework according to an embodiment of the present invention. Each smart meter can have a unique identifier (such as a table number). The smart meters of all users in a certain area (such as a certain cell) access the DCU in the area, and the DCU communicates with the main station.

在基于AMI的智能抄表***中，本发明中的主站为AMI主站。AMI主站可以包括数据收集平台(Data collection platform，简称DCP)设备，也称为前置机，通过网络与DCU通信。In the AMI-based smart meter reading system, the primary station in the present invention is an AMI primary station. The AMI primary station may include a Data Collection Platform (DCP) device, also referred to as a front-end machine, that communicates with the DCU over the network.

其中，主站，用于向DCU发送标识符通知消息，标识符通知消息中包括第一标识符。The primary station is configured to send an identifier notification message to the DCU, where the identifier notification message includes the first identifier.

DCU，用于接收主站发送的标识符通知消息，标识符通知消息中包括第一标识符，根据标识符通知消息，为第一标识符分配第一通信地址，并保存第一标识符与第一通信地址对，广播发送通信地址分配消息，通信地址分配消息中包括第一标识符和第一通信地址对；a DCU, configured to receive an identifier notification message sent by the primary station, where the identifier notification message includes a first identifier, assigning a first communication address to the first identifier according to the identifier notification message, and saving the first identifier and the first identifier a communication address pair, a broadcast transmission communication address assignment message, and a communication address assignment message Include a first identifier and a first communication address pair;

若干智能仪表中每个智能仪表，可以用于接收DCU广播发送的通信地址分配消息，通信地址分配消息中包括第一标识符和第一通信地址对，第一通信地址为DCU根据第一标识符所分配，当确定第一标识符为智能仪表的标识符时，配置第一通信地址，若确定第一标识符不是自身的标识符，可以结束处理。Each smart meter of the plurality of smart meters may be configured to receive a communication address assignment message sent by the DCU broadcast, where the communication address assignment message includes a first identifier and a first communication address pair, where the first communication address is a DCU according to the first identifier The allocation, when determining that the first identifier is an identifier of the smart meter, configuring the first communication address, and if it is determined that the first identifier is not its own identifier, the processing may be ended.

具体实施中，DCU可以接收主站发送的标识符通知消息，然后可以为标识符通知消息中的第一标识符分配对应的通信地址(即第一通信地址)，并保存第一标识符与第一通信地址对，如建立智能仪表的标识符与通信地址的对应关系表，然后DCU以广播方式发送通信地址分配消息，通信地址分配消息中可以包括第一标识符和第一通信地址对。DCU可以一次广播方式仅发送一组智能仪表的标识符和通信地址对，也可以一次广播方式发送多组标识符和通信地址对，以提高通信地址分配的效率。In a specific implementation, the DCU may receive the identifier notification message sent by the primary station, and then may assign a corresponding communication address (ie, the first communication address) to the first identifier in the identifier notification message, and save the first identifier and the first identifier. A communication address pair, such as a correspondence table between the identifier of the smart meter and the communication address, and then the DCU broadcasts the communication address assignment message, and the communication address assignment message may include the first identifier and the first communication address pair. The DCU can transmit only one set of smart meter identifiers and communication address pairs in a single broadcast manner, or can send multiple sets of identifiers and communication address pairs in a single broadcast manner to improve the efficiency of communication address allocation.

智能仪表接收到DCU发送通信地址分配消息后，可以确定第一标识符是否是自身的标识符，如果是，则可以配置第一通信地址，如果不是，则可以丢弃该通信地址分配消息。After receiving the communication address assignment message by the DCU, the smart meter may determine whether the first identifier is its own identifier. If yes, the first communication address may be configured. If not, the communication address assignment message may be discarded.

本发明实施例中，DCU接收主站发送的标识符通知消息，标识符通知消息中包括第一标识符，DCU根据标识符通知消息，为第一标识符分配第一通信地址，并保存第一标识符与第一通信地址对，DCU广播发送通信地址分配消息，通信地址分配消息中包括第一标识符和第一通信地址对，以使具有第一标识符的第一智能仪表配置第一通信地址，这样，可以根据接收到的智能仪表的标识符，自动为智能仪表分配通信地址，无需维护人员手动在主站、DCU和智能仪表中配置各智能仪表的通信地址，从而可以降低部署成本，提高通信地址分配的效率和准确性。In the embodiment of the present invention, the DCU receives the identifier notification message sent by the primary station, where the identifier notification message includes the first identifier, and the DCU allocates the first communication address to the first identifier according to the identifier notification message, and saves the first And the first communication address pair, the DCU broadcasts a communication address assignment message, the communication address assignment message includes a first identifier and a first communication address pair, so that the first smart meter having the first identifier configures the first communication The address, in this way, can automatically assign a communication address to the smart meter according to the identifier of the received smart meter, and the maintenance address is not required by the maintenance personnel to manually configure the communication address of each smart meter in the main station, the DCU, and the smart meter, thereby reducing the deployment cost. Improve the efficiency and accuracy of communication address allocation.

本发明实施例提供了一种分配通信地址的方法，通过主站、DCU和智能仪表之间的交互，完成通信地址的分配。其中，智能仪表可以是智能电表、智能水表或智能气表等。本实施例以智能仪表为智能电表为例进行说明，其他情况与之类似。The embodiment of the invention provides a method for allocating a communication address, and the assignment of the communication address is completed by the interaction between the primary station, the DCU and the smart meter. Among them, the smart meter can be a smart meter, a smart water meter or a smart gas meter. In this embodiment, the smart meter is used as an example for the smart meter, and other situations are similar.

如图1所示，该方法中DCU的处理流程可以包括如下的步骤：As shown in FIG. 1, the processing flow of the DCU in the method may include the following steps:

步骤101，DCU接收主站发送的标识符通知消息，标识符通知消息中包括第一标识符。Step 101: The DCU receives an identifier notification message sent by the primary station, where the identifier notification message includes First identifier.

在实施中，主站可以将需要分配通信地址的电表的标识符(即第一标识符)添加到标识符通知消息中，然后可以将标识符通知消息发送给相应的DCU，DCU则可以接收主站发送的标识符通知消息，并可以对标识符通知消息进行解析，获取第一标识符，并可以将接收到的第一标识符进行存储。In an implementation, the primary station may add an identifier (ie, a first identifier) of the electrical meter that needs to be assigned a communication address to the identifier notification message, and then may send the identifier notification message to the corresponding DCU, and the DCU may receive the primary The identifier notification message sent by the station, and the identifier notification message may be parsed, the first identifier is obtained, and the received first identifier may be stored.

主站可以向DCU一次仅发送一个电表的标识符，也可以向DCU一次发送多个电表的标识符，则标识符通知消息中还可以包括第二标识符。The primary station may send only one identifier of the electric meter to the DCU at a time, or may send the identifiers of the plurality of electric meters to the DCU at a time, and the identifier notification message may further include the second identifier.

步骤102，DCU根据标识符通知消息，为第一标识符分配第一通信地址，并保存第一标识符与第一通信地址对。Step 102: The DCU allocates a first communication address to the first identifier according to the identifier notification message, and saves the first identifier and the first communication address pair.

在实施中，DCU中可以预先存储可以为电表分配的通信地址，并且可以记录已使用的通信地址和未使用的通信地址，以便进行分配处理。电表的通信地址可以用8位二进制数来表示。DCU接收到主站发送的标识符通知消息后，对该标识符通知消息进行解析，获取第一标识符，然后可以在DCU预先存储的通信地址中，确定未使用的通信地址，在未使用的通信地址中，获取第一通信地址，进而可以将第一通信地址分配给第一标识符对应的电表，并可以保存第一标识符与第一通信地址对，建立标识符与通信地址的对应关系。DCU可以以对应关系表的形式来存储标识符与通信地址对，如表1所示：In an implementation, a communication address that can be assigned to the meter can be pre-stored in the DCU, and the used communication address and the unused communication address can be recorded for distribution processing. The communication address of the meter can be represented by an 8-bit binary number. After receiving the identifier notification message sent by the primary station, the DCU parses the identifier notification message to obtain the first identifier, and then can determine the unused communication address in the communication address pre-stored by the DCU, in the unused In the communication address, the first communication address is obtained, and the first communication address may be allocated to the electricity meter corresponding to the first identifier, and the first identifier and the first communication address pair may be saved, and the correspondence between the identifier and the communication address is established. . The DCU can store the identifier and the communication address pair in the form of a correspondence table, as shown in Table 1:

表1Table 1

电表的标识符Meter identifier	通信地址contact address
12301230	0000110000001100
12311231	0000110100001101
12321232	0000111000001110
12331233	0000111100001111

可选的，上述标识符通知消息中还包括第二标识符，在步骤102的处理过程可以如下：DCU根据标识符通知消息，为第一标识符分配第一通信地址，为第二标识符分配第二通信地址，并保存第一标识符与第一通信地址对以及第二标识符与第二通信地址对。Optionally, the identifier notification message further includes a second identifier, and the process in step 102 may be as follows: the DCU allocates a first communication address to the first identifier according to the identifier notification message, and allocates the second identifier. a second communication address and storing the first identifier and the first communication address pair and the second identifier and the second communication address pair.

在实施中，DCU接收到收主站发送的标识符通知消息后，可以对该标识符通知消息进行解析，获取第一标识符和第二标识符，然后可以在DCU预先存储的未使用的通信地址中，选取两个通信地址(即第一通信地址和第二通信地址)，将第一通信地址分配给第一标识符对应的电表，将第二通信地址分配给第二标识符对应的电表，并可以保存第一标识符与第一通信地址对，以及第二标识符与第二通信地址对，建立标识符与通信地址的对应关系。In an implementation, after receiving the identifier notification message sent by the receiving station, the DCU may parse the identifier notification message to obtain the first identifier and the second identifier, and then may be pre-stored in the DCU. Among the unused communication addresses, two communication addresses (ie, the first communication address and the second communication address) are selected, the first communication address is assigned to the electricity meter corresponding to the first identifier, and the second communication address is assigned to the second communication address. The electric meter corresponding to the identifier, and may store the first identifier and the first communication address pair, and the second identifier and the second communication address pair, and establish a correspondence between the identifier and the communication address.

更进一步地，DCU可以按照标识符通知消息中携带第一标识符和第二标识符的顺序，依次为第一标识符和第二标识符分配第一通信地址和第二通信地址。Further, the DCU may sequentially assign the first communication address and the second communication address to the first identifier and the second identifier in an order in which the identifier notification message carries the first identifier and the second identifier.

DCU中可以设置有地址池，该地址池中可以存储有全部的通信地址，并且将已经分配给电表的通信地址，标记为已使用的通信地址，将未做分配的通信地址，标记为未使用的通信地址。或者，DCU可以在地址池中只存储未使用的通信地址(即，未做分配的通信地址)。或者，DCU可以有两个地址池，分别存储已使用的通信地址(即，已经分配给电表的通信地址)和未使用的通信地址(即，未做分配的通信地址)。An address pool can be set in the DCU, and all the communication addresses can be stored in the address pool, and the communication address already assigned to the electricity meter is marked as the used communication address, and the unassigned communication address is marked as unused. Communication address. Alternatively, the DCU can store only unused communication addresses (ie, unassigned communication addresses) in the address pool. Alternatively, the DCU may have two address pools that store the used communication address (ie, the communication address that has been assigned to the meter) and the unused communication address (ie, the unassigned communication address).

由于电表的通信地址用8位二进制数来表示，DCU接收到收第一标识符和第二标识符后，可以在未使用的通信地址中，按照通信地址的顺序，获取第一通信地址和第二通信地址，并根据标识符通知消息中携带第一标识符和第二标识符的顺序，依次为第一标识符和第二标识符分配第一通信地址和第二通信地址，并可以将电表的标识符与通信地址进行对应记录。例如，DCU从地址池获取到当前未使用的通信地址为00001100、00001101、00001110、00001111，接收到的标识符为1230和1231，则可以将00001100分配给1230对应的电表，将00001101分配给1231对应的电表。Since the communication address of the electric meter is represented by an 8-bit binary number, after receiving the first identifier and the second identifier, the DCU can obtain the first communication address and the first communication address in the order of the communication address in the unused communication address. Transmitting the first communication address and the second communication address, and sequentially assigning the first communication address and the second communication address to the first identifier and the second identifier, according to the order of carrying the first identifier and the second identifier in the identifier notification message The identifier is recorded corresponding to the communication address. For example, if the DCU obtains the currently unused communication addresses from the address pool to 00001100, 00001101, 00001110, and 00001111, and the received identifiers are 1230 and 1231, you can assign 00001100 to the 1230 corresponding meter and 00001101 to 1231. Electric meter.

步骤103，DCU广播发送通信地址分配消息，通信地址分配消息中包括第一标识符和第一通信地址对，以使具有第一标识符的第一智能仪表配置第一通信地址。Step 103: The DCU broadcasts a communication address assignment message, where the communication address assignment message includes a first identifier and a first communication address pair, so that the first smart meter having the first identifier configures the first communication address.

在实施中，DCU为具有第一标识符的第一电表配置第一通信地址后，可以将第一通信地址和第一标识符对放在通信地址分配消息中，该通信地址分配消息为广播消息，然后可以将通信地址分配消息以广播的形式发送给与该DCU连接的电表。DCU与电表之间采用485通信协议来进行通信。DCU向电表广播的通信地址分配消息可以是Modbus格式的报文，也可以是高级数据链路控制(High-Level Data Link Control，简称HDLC)格式的报文。 In an implementation, after the DCU configures the first communication address for the first meter having the first identifier, the first communication address and the first identifier pair may be placed in a communication address assignment message, and the communication address assignment message is a broadcast message. The communication address assignment message can then be sent in broadcast form to the meter connected to the DCU. The 485 communication protocol is used between the DCU and the meter for communication. The message that the DCU broadcasts to the communication address of the meter can be a message in the Modbus format or a packet in the High-Level Data Link Control (HDLC) format.

Modbus格式的报文如下：The message in Modbus format is as follows:

地址域为8位(bit)，用于写入目的地址，通常用8位二进制数来表示。地址范围为十进制0～255，其中，0为广播地址，248～255为保留地址，可分配给节点的地址为1～247。本发明中，DCU向电表广播的通信地址分配消息中，该地址域中写入00000000。The address field is 8 bits and is used to write the destination address, usually represented by an 8-bit binary number. The address range is 0 to 255, where 0 is the broadcast address, 248 to 255 is the reserved address, and the address that can be assigned to the node is 1 to 247. In the present invention, the DCU writes a message to the communication address of the electric meter broadcast, and the address field writes 00000000.

功能域中可以使用自定义的功能码，专门指示地址分配，该功能码需要与其他功能码区分开来，以便电表进行识别，该功能码的具体值可以由各电表的厂家自行定义。The function field can use a custom function code to specifically indicate the address assignment. The function code needs to be distinguished from other function codes for the meter to recognize. The specific value of the function code can be defined by the manufacturer of each meter.

数据域用于携带通信数据。本发明中，DCU向电表广播发送的通信地址分配消息中，在数据域中写入标识符和通信地址对。数据域中的数据格式可以如下：The data field is used to carry communication data. In the present invention, in the communication address assignment message transmitted by the DCU to the meter broadcast, an identifier and a communication address pair are written in the data field. The data format in the data domain can be as follows:

{{

标识符；Identifier

通信地址；contact address;

}}

DCU可以一次为一个电表分配通信地址，也可以一次为多个电表分配通信地址，对于DCU一次为多个电表分配通信地址的情况，不同电表的标识符和通信地址对可以按照上述格式，一起写入到数据域中。The DCU can assign a communication address to one meter at a time, or can assign a communication address to multiple meters at a time. For the case where the DCU assigns a communication address to multiple meters at a time, the identifiers and communication address pairs of different meters can be written together according to the above format. Enter the data field.

HDLC格式的报文如下：The packets in HDLC format are as follows:

其中，0x7e用于表示报文的开头和结尾。Where 0x7e is used to indicate the beginning and end of the message.

目的地址域可以为16位(bit)，用于写入目的地址，源地址域为16位(bit)，用于写入源地址，通常都是用十六进制数来表示。地址范围可以是0～0x3FFF，其中，0x3FFF为广播地址，0x00002～0x000F为保留地址，其余地址可以分配给节点。本发明中，当DCU向电表广播发送的通信地址分配消息采用HDLC格式的报文时，可以在源地址域中写入DCU的地址，目的地址域中写入广播地址0x3FFF。The destination address field can be 16 bits (bit) for writing to the destination address. The source address field is 16 bits (bit) for writing to the source address, usually expressed in hexadecimal numbers. The address range can be 0~0x3FFF, where 0x3FFF is the broadcast address, 0x00002~0x000F is the reserved address, and the remaining addresses can be assigned to node. In the present invention, when the communication address assignment message sent by the DCU to the meter broadcast uses the HDLC format message, the address of the DCU can be written in the source address field, and the broadcast address 0x3FFF is written in the destination address field.

用户数据信息用于携带通信数据。DCU可以在用户数据信息中写入标识符和通信地址对。用户数据信息中的数据格式可以同上Modbus报文。User data information is used to carry communication data. The DCU can write an identifier and a communication address pair in the user data information. The data format in the user data information can be the same as the Modbus message.

DCU可以一次为一个智能仪表分配通信地址，也可以一次为多个智能仪表分配通信地址，对于DCU一次为多个电表分配通信地址的情况，不同电表的标识符和通信地址对可以按照上述定义的数据格式，一起写入到用户数据信息中。The DCU can assign a communication address to one smart meter at a time, or can assign a communication address to multiple smart meters at a time. For the case where the DCU assigns a communication address to multiple electric meters at a time, the identifiers and communication address pairs of different electric meters can be defined as above. The data format is written together into the user data information.

可选的，具有第一标识符的第一电表成功配置第一通信地址后，可以向DCU发送地址配置配成功消息，相应的，DCU的处理可以如下：DCU接收具有第一标识符的第一智能仪表发送的地址配置成功消息，地址配置成功消息中包括所述第一标识符。所述地址配置成功消息中还包括所述第一通信地址。Optionally, after the first power meter having the first identifier successfully configures the first communication address, the address configuration success message may be sent to the DCU. Accordingly, the processing of the DCU may be as follows: the DCU receives the first identifier with the first identifier. The address configuration success message sent by the smart meter includes the first identifier in the address configuration success message. The address configuration success message further includes the first communication address.

DCU接收到所述第一电表的地址配置配成功消息后，可以确认所述第一电表成功配置地址。如果DCU广播发送通信地址分配消息后，在预设时长内未接收到所述第一电表的地址配置配成功消息，则认为本次所述第一电表没有成功配置地址，可以重新广播发送通信地址分配消息，其中携带所述第一电表的第一标识符和第一通信地址对。这样可以提高地址分配的准确性。在一次为多个电表分配通信地址的情况下，如果在预设时长内没有接收到其中某个(或某些)电表的地址配置成功消息，则DCU认为该(些)电表没有成功配置地址，再次广播发送通信地址分配消息时，只需要在消息中携带该(些)电表的标识符和通信地址对。这样既提高了地址分配的效率又能保证准确性。After receiving the address configuration success message of the first power meter, the DCU can confirm that the first power meter successfully configures the address. If the DCU broadcasts the communication address assignment message and does not receive the address configuration success message of the first power meter within the preset time period, it is considered that the first power meter does not successfully configure the address, and the communication address can be re-broadcasted. And assigning a message carrying the first identifier and the first communication address pair of the first meter. This can improve the accuracy of address allocation. In the case of assigning a communication address to a plurality of electric meters at a time, if the address configuration success message of one (or some) of the electric meters is not received within the preset time period, the DCU considers that the electric meter(s) have not successfully configured the address. When the communication address assignment message is broadcast again, it is only necessary to carry the identifier of the meter(s) and the communication address pair in the message. This not only improves the efficiency of address allocation but also ensures accuracy.

如图2所示，该方法中电表的处理流程可以包括如下的步骤：As shown in FIG. 2, the processing flow of the electric meter in the method may include the following steps:

步骤201，智能仪表接收DCU广播发送的通信地址分配消息，通信地址分配消息中包括第一标识符和第一通信地址对，第一通信地址为DCU根据第一标识符所分配。Step 201: The smart meter receives a communication address assignment message sent by the DCU broadcast, where the communication address assignment message includes a first identifier and a first communication address pair, and the first communication address is allocated by the DCU according to the first identifier.

在实施中，DCU将通信地址分配消息广播给电表后，电表则可以接收到DCU发送的通信地址分配消息，然后可以对该通信地址分配消息进行解析，获取其中的第一标识符和第一通信地址，以便进行后续处理。In an implementation, after the DCU broadcasts the communication address assignment message to the electricity meter, the electricity meter can receive the communication address assignment message sent by the DCU, and then parse the communication address assignment message to obtain the first identifier and the first communication. Address for subsequent processing.

步骤202，当智能仪表确定第一标识符为智能仪表的标识符时，智能仪表配置第一通信地址。Step 202: When the smart meter determines that the first identifier is an identifier of the smart meter, the smart meter is configured Set the first communication address.

在实施中，电表获取到通信地址分配消息中的第一标识符和第一通信地址后，可以获取该电表的标识符，如果第一标识符与该电表的标识符相同(一致)，则该电表可以对第一通信地址进行存储，将第一通信地址作为自己(该电表)的通信地址。如果通信地址分配消息中的第一标识符与该电表的标识符不同(不一致)，则可以丢弃该通信地址分配消息。In an implementation, after the electric meter acquires the first identifier and the first communication address in the communication address assignment message, the identifier of the electric meter may be acquired, and if the first identifier is the same (identical) as the identifier of the electric meter, The meter can store the first communication address as the communication address of the self (the meter). If the first identifier in the communication address assignment message is different (inconsistent) from the identifier of the meter, the communication address assignment message may be discarded.

可选的，智能仪表配置成功后，可以通知DCU，相应的处理过程可以如下：智能仪表向DCU发送地址配置成功消息。Optionally, after the smart meter is configured successfully, the DCU can be notified, and the corresponding processing process can be as follows: the smart meter sends an address configuration success message to the DCU.

在实施中，具有第一标识符的第一电表成功配置第一通信地址后，可以向DCU发送地址配置成功消息，以使DCU准确获知该第一电表是否成功配置了地址。如果DCU广播发送通信地址分配消息后，在预设时长内未接收到地址配置成功消息，则可以重新广播发送通信地址分配消息。In an implementation, after the first electric meter having the first identifier successfully configures the first communication address, the address configuration success message may be sent to the DCU, so that the DCU can accurately know whether the first electric meter successfully configures the address. If the DCU broadcasts the communication address assignment message and does not receive the address configuration success message within the preset duration, the transmission communication address assignment message may be rebroadcast.

本发明实施例提供了一种分配通信地址的***，包括主站，数据集中单元DCU和智能仪表，如图4所示，该***中，为智能仪表分配通信地址的过程包括如下的步骤：An embodiment of the present invention provides a system for allocating a communication address, including a primary station, a data centralized unit DCU, and a smart meter. As shown in FIG. 4, the process of allocating a communication address for a smart meter includes the following steps:

步骤401，主站向DCU发送标识符通知消息，所述标识符通知消息中包括第一标识符。Step 401: The primary station sends an identifier notification message to the DCU, where the identifier notification message includes a first identifier.

主站可以将需要分配通信地址的智能仪表的标识符(即第一标识符)添加到标识符通知消息中，然后可以将该标识符通知消息发送给相应的DCU。具体地，主站知道所述智能仪表连接到该DCU，当主站确定该智能仪表需要分配通信地址时，例如该智能仪表刚刚加入该***时，主站向该智能仪表连接的DCU 发送标识符通知消息，所述标识符通知消息中包括该智能仪表的标识符，即第一标识符。The primary station may add an identifier (ie, a first identifier) of the smart meter that needs to be assigned a communication address to the identifier notification message, which may then be sent to the corresponding DCU. Specifically, the primary station knows that the smart meter is connected to the DCU, and when the primary station determines that the smart meter needs to allocate a communication address, for example, when the smart meter just joins the system, the DCU connected to the smart meter by the primary station An identifier notification message is sent, the identifier notification message including an identifier of the smart meter, that is, a first identifier.

当然，主站也可以一次向该DCU下发多个标识符，以使该DCU为该多个标识符对应的智能仪表，分别分配通信地址。Of course, the primary station may also send multiple identifiers to the DCU at a time, so that the DCU allocates communication addresses for the smart meters corresponding to the multiple identifiers.

DCU可以对标识符通知消息进行解析，获取第一标识符，并可以将接收到的第一标识符进行存储。The DCU may parse the identifier notification message, obtain the first identifier, and store the received first identifier.

步骤402，DCU接收主站发送的所述标识符通知消息，根据所述标识符通知消息，为第一标识符分配第一通信地址，并保存第一标识符与第一通信地址对。Step 402: The DCU receives the identifier notification message sent by the primary station, allocates a first communication address to the first identifier according to the identifier notification message, and saves the first identifier and the first communication address pair.

在实施中，DCU中可以预先存储可以为电表分配的通信地址，并且可以记录已使用的通信地址和未使用的通信地址，以便进行分配处理。电表的通信地址可以用8位二进制数来表示。DCU接收到收主站发送的标识符通知消息后，对该标识符通知消息进行解析，获取第一标识符，然后可以在DCU预先存储的通信地址中，确定未使用的通信地址，在未使用的通信地址中，获取第一通信地址，进而可以将第一通信地址分配给第一标识符对应的电表，并可以保存标识符与通信地址对，建立标识符与通信地址的对应关系，例如表1所示。In an implementation, a communication address that can be assigned to the meter can be pre-stored in the DCU, and the used communication address and the unused communication address can be recorded for distribution processing. The communication address of the meter can be represented by an 8-bit binary number. After receiving the identifier notification message sent by the receiving station, the DCU parses the identifier notification message to obtain the first identifier, and then can determine the unused communication address in the communication address pre-stored by the DCU, and is not used. Obtaining a first communication address, and then assigning the first communication address to the electricity meter corresponding to the first identifier, and storing the identifier and the communication address pair, and establishing a correspondence between the identifier and the communication address, for example, 1 is shown.

步骤403，DCU广播发送通信地址分配消息，通信地址分配消息中包括第一标识符和第一通信地址对。Step 403: The DCU broadcasts a communication address assignment message, where the communication address assignment message includes a first identifier and a first communication address pair.

在实施中，DCU为具有第一标识符的第一电表配置第一通信地址后，可以将第一通信地址和第一标识符对放在通信地址分配消息中，然后以广播的形式发送给与该DCU连接的电表。DCU与电表之间的可以采用485通信协议来进行通信。在实际中，DCU向电表广播的通信地址分配消息可以采用Modbus格式的报文，也可以是格式的报文。In an implementation, after the DCU configures the first communication address for the first electricity meter having the first identifier, the first communication address and the first identifier pair may be placed in the communication address assignment message, and then sent in the form of a broadcast. The meter connected to the DCU. The DCU and the meter can communicate using the 485 communication protocol. In practice, the DCU can assign a message to the communication address broadcasted by the meter in a Modbus format message or a formatted message.

步骤404，智能仪表接收DCU广播发送的通信地址分配消息，通信地址分配消息中包括第一标识符和第一通信地址对。Step 404: The smart meter receives a communication address assignment message sent by the DCU broadcast, where the communication address assignment message includes a first identifier and a first communication address pair.

在实施中，电表可以接收DCU广播发送的通信地址分配消息，然后可以对该通信地址分配消息进行解析，获取其中的第一标识符和第一通信地址，以便进行后续处理。In an implementation, the electric meter may receive the communication address assignment message sent by the DCU broadcast, and then parse the communication address assignment message to obtain the first identifier and the first communication address for subsequent processing.

步骤405，当智能仪表确定第一标识符为自身(即，所述智能仪表)的标识符时，所述智能仪表配置第一通信地址。 Step 405: When the smart meter determines that the first identifier is an identifier of itself (ie, the smart meter), the smart meter configures the first communication address.

在实施中，电表获取到通信地址分配消息中的第一标识符和第一通信地址后，可以获取该电表的标识符，如果第一标识符与该电表的标识符相同(一致)，则该电表可以对第一通信地址进行存储，将第一通信地址作为自己的通信地址。如果第一标识符与该电表的标识符不同(不一致)，则可以丢弃该通信地址分配消息。In an implementation, after the electric meter acquires the first identifier and the first communication address in the communication address assignment message, the identifier of the electric meter may be acquired, and if the first identifier is the same (identical) as the identifier of the electric meter, The meter can store the first communication address and use the first communication address as its own communication address. If the first identifier is different (inconsistent) from the identifier of the meter, the communication address assignment message can be discarded.

另外，本发明实施例还提供了基于上述为智能仪表分配的通信地址，进行智能仪表数据查询的处理过程，其中，智能仪表可以是智能电表、智能水表或智能气表等。本实施例以智能仪表为智能电表为例进行说明，其他情况与之类似。如图5所示，该智能仪表数据查询的过程具体可以包括以下步骤：In addition, the embodiment of the present invention further provides a process for performing smart meter data query based on the communication address assigned to the smart meter, wherein the smart meter may be a smart meter, a smart water meter, or a smart gas meter.

The primary station can receive the electric meter data query instruction corresponding to the DCU, and then obtain the identifier of the DCU, and then determine the identifier of the electric meter connected to the DCU according to the correspondence between the pre-stored identifier and the identifier of the DCU. Then you can The DCU sends a first data query message, the first data query message including an identifier of a number of meters connected to the DCU. Alternatively, the maintenance personnel may send a data query message (which may be referred to as a third data query message) that does not carry an identifier to the DCU through the primary station, and after receiving the third data query message, the DCU may send all the electric meters connected to the DCU. Send a data query message to query the meter data.

步骤502、DCU根据第一标识符，获取第一通信地址。Step 502: The DCU acquires the first communication address according to the first identifier.

在实施中，DCU接收主站发送的第一数据查询消息后，可以对第一数据查询消息进行解析，获取第一数据查询消息中的第一标识符，然后可以根据预先存储的标识符与通信地址的对应关系，确定第一标识符对应的第一通信地址，In an implementation, after receiving the first data query message sent by the primary station, the DCU may parse the first data query message, obtain the first identifier in the first data query message, and then communicate with the identifier according to the pre-stored identifier. Corresponding relationship of the address, determining a first communication address corresponding to the first identifier,

步骤503、DCU向具有第一标识符的第一智能仪表发送第二数据查询消息，第二数据查询消息中包括第一通信地址。Step 503: The DCU sends a second data query message to the first smart meter having the first identifier, where the second data query message includes the first communication address.

在实施中，DCU获取第一通信地址后，可以向具有第一标识符的第一智能仪表发送第二数据查询消息。对于第二数据查询消息是Modbus格式的报文的情况，DCU可以将第一通信地址写入报文的地址域中，对于第二数据查询消息是HDLC格式的报文的情况，DCU可以将第一通信地址写入报文的目的地址域中。In an implementation, after the DCU acquires the first communication address, the second data query message may be sent to the first smart meter having the first identifier. For the case where the second data query message is a message in the Modbus format, the DCU may write the first communication address into the address field of the message. For the case where the second data query message is a message in the HDLC format, the DCU may A communication address is written in the destination address field of the message.

步骤504、第一智能仪表接收DCU发送的第二数据查询消息，第二数据查询消息中包括第一通信地址。Step 504: The first smart meter receives the second data query message sent by the DCU, where the second data query message includes the first communication address.

在实施中，DCU基于第一通信地址向上述第一电表发送第二数据查询消息后，该第一电表则可以接收DCU发送的第二数据查询消息，然后可以对第二数据查询消息进行解析，获取其中的第一通信地址。In an implementation, after the DCU sends the second data query message to the first power meter based on the first communication address, the first power meter may receive the second data query message sent by the DCU, and then parse the second data query message.
