In the embodiment of the present invention, DCU receives the identifier notification message that main website sends, identifier notification message Include the first identifier, DCU, according to identifier notification message, is that the first identifier distributes first communicatedly Location, and the first identifier and the first mailing address pair are preserved, DCU broadcast transmission mailing address assignment messages, Mailing address assignment messages include the first identifier and the first mailing address pair, so as to have the first identifier The first intelligence instrument configure the first mailing address, as such, it is possible to according to the mark of the intelligence instrument for receiving Symbol, distributes mailing address for intelligence instrument automatically, and Maintenance free personnel are manually in main website, DCU and Intelligent Instrument The mailing address of each intelligence instrument is configured in table, such that it is able to reduce lower deployment cost, mailing address distribution is improved Efficiency and accuracy.

A kind of method of distribution mailing address is embodiments provided, by main website, DCU and Intelligent Instrument Interaction between table, completes the distribution of mailing address.Wherein, intelligence instrument can be intelligent electric meter, intelligence Water meter or intelligent gas meter etc..The present embodiment is illustrated so that intelligence instrument is as intelligent electric meter as an example, other situations It is similar to therewith.

As shown in figure 1, the handling process of DCU can include the steps in the method：

Step 101, DCU receive the identifier notification message that main website sends, and identifier notification message includes First identifier.

In force, main website can be by the identifier (i.e. the first identifier) of the ammeter for needing to distribute mailing address It is added in identifier notification message, then identifier notification message can be sent to corresponding DCU, DCU The identifier notification message of main website transmission can then be received, it is possible to which identifier notification message is parsed, Obtain the first identifier, it is possible to which the first identifier for receiving is stored.

Main website once can only send the identifier of an ammeter to DCU, it is also possible to once send to DCU The identifier of multiple ammeters, then can also include the second identifier in identifier notification message.

Step 102, DCU, according to identifier notification message, are that the first identifier distributes the first mailing address, And preserve the first identifier and the first mailing address pair.

In force, it is the mailing address of ammeter distribution that can prestore in DCU, and can be remembered Mailing address and untapped mailing address that record has been used, to be allocated process.Ammeter is communicatedly Location can be represented with 8 bits.It is after DCU receives the identifier notification message of main website transmission, right The identifier notification message is parsed, and obtains the first identifier, then can be in leading to that DCU is prestored In letter address, untapped mailing address is determined, in untapped mailing address, obtain first communicatedly Location, and then the first mailing address can be distributed to the corresponding ammeter of the first identifier, it is possible to preserve first Identifier and the first mailing address pair, set up the corresponding relation of identifier and mailing address.DCU can be with right Answer the form of relation table to store identifier and mailing address pair, as shown in table 1：

Table 1

The identifier of ammeter	Mailing address
		1230	00001100
1231	00001101
		1232	00001110
1233	00001111

Optionally, also include the second identifier in above-mentioned identifier notification message, in the process of step 102 Journey can be as follows：DCU is that the first identifier distributes the first mailing address, is according to identifier notification message Second identifier distribute the second mailing address, and preserve the first identifier and the first mailing address to and second Identifier and the second mailing address pair.

In force, after DCU is received and is received the identifier notification message that main website sends, can be to the identifier Notification message is parsed, and is obtained the first identifier and the second identifier, then can be prestored in DCU Untapped mailing address in, choose two mailing addresses (i.e. the first mailing address and the second mailing address), First mailing address is distributed to into the corresponding ammeter of the first identifier, the second mailing address is distributed to into the second mark Know the corresponding ammeter of symbol, it is possible to preserve the first identifier and the first mailing address pair, and the second identifier With the second mailing address pair, the corresponding relation of identifier and mailing address is set up.

Further, DCU can be identified according to the first identifier and second is carried in identifier notification message The order of symbol, is followed successively by the first identifier and the second identifier distributes the first mailing address and the second mailing address.

Address pool can be provided with DCU, can be stored with the address pool whole mailing addresses, and The mailing address of ammeter will be already allocated to, the mailing address for having used will be labeled as, the communication for distributing will not done Address, is labeled as untapped mailing address.Or, DCU can only store untapped in address pool Mailing address (that is, does not do the mailing address for distributing).Or, DCU can have two address pools, deposit respectively Mailing address (that is, being already allocated to the mailing address of ammeter) and untapped mailing address that storage has been used (that is, not doing the mailing address for distributing).

Due to ammeter mailing address with 8 bits representing, DCU receive the first identifier of receipts and After second identifier, first can be obtained in untapped mailing address, according to the order of mailing address Mailing address and the second mailing address, and mark according to the first identifier and second is carried in identifier notification message Know the order of symbol, be followed successively by the first identifier and the second identifier distributes the first mailing address and second communicatedly Location, it is possible to which the identifier of ammeter and mailing address are carried out into corresponding record.For example, DCU is obtained from address pool It is 00001100,00001101,00001110,00001111 to get not currently used mailing address, is connect The identifier for receiving is 1230 and 1231, then can distribute to 1230 corresponding ammeters by 00001100, will 00001101 distributes to 1231 corresponding ammeters.

Step 103, DCU broadcast transmission mailing address assignment messages, mailing address assignment messages include One identifier and the first mailing address pair, so that the configuration of the first intelligence instrument with the first identifier first is led to Letter address.

In force, DCU is after the first ammeter with the first identifier configures the first mailing address, can be with By the first mailing address and the first identifier to being placed in mailing address assignment messages, the mailing address distribution disappears Cease for broadcast, then mailing address assignment messages can be sent in the form of broadcasting and the DCU connects The ammeter for connecing.Adopt 485 communication protocols to be communicated between DCU and ammeter.DCU is broadcasted to ammeter Mailing address assignment messages can be the message of Modbus forms, or High-Level Data Link Control The message of (High-Level Data Link Control, abbreviation HDLC) form.

The message of Modbus forms is as follows：

Address field is 8 (bit), for writing destination address, is represented generally with 8 bits.Ground Location scope is decimal scale 0～255, wherein, 0 is broadcast address, and 248～255 is reserved address, can be distributed to Address of node is 1～247.In the present invention, in the mailing address assignment messages that DCU is broadcasted to ammeter, should 00000000 is write in address field.

Can use self-defining function code in functional domain, it is special to indicate address distribution, the function code need with Other functions code makes a distinction, and so that ammeter is identified, the occurrence of the function code can be by each ammeter Producer's self-defining.

Data field is used to carry communication data.In the present invention, mailing addresses point of the DCU to ammeter broadcast transmission In with message, identifier and mailing address pair are write in data field.Data form in data field can be as Under：

{

Identifier；

Mailing address；

}

DCU may be calculated once for an ammeter distribution mailing address, it is also possible to once communicate for the distribution of multiple ammeters Address, when once distributing mailing address for multiple ammeters for DCU, the identifier of different ammeters and logical Letter address is to can be written in data field together according to above-mentioned form.

The message of HDLC forms is as follows：

Wherein, 0x7e is used for the beginning and end for representing message.

Destination address domain can be 16 (bit), and for writing destination address, source address field is 16 (bit), For writing source address, generally all it is representing with hexadecimal number.Address realm can be 0～0x3FFF, Wherein, 0x3FFF is broadcast address, and 0x00002～0x000F is reserved address, and remaining address can be distributed to Node.In the present invention, when DCU adopts HDLC forms to the mailing address assignment messages of ammeter broadcast transmission Message when, the address of DCU can be write in source address field, destination address writes broadcast address in domain 0x3FFF。

User data information is used to carry communication data.DCU can write identifier in user data information With mailing address pair.Data form in user data information can ibid Modbus messages.

DCU may be calculated once for an intelligence instrument distribution mailing address, it is also possible to be once multiple intelligence instruments Distribution mailing address, when once distributing mailing address for multiple ammeters for DCU, the mark of different ammeters Symbol and mailing address are known to being written in user data information together according to data form defined above.

Optionally, the first ammeter with the first identifier is successfully configured after the first mailing address, can be to DCU Send address configuration and match somebody with somebody success message, accordingly, the process of DCU can be as follows：DCU is received with first The address configuration success message that first intelligence instrument of identifier sends, address configuration success message include institute State the first identifier.Also include first mailing address in the address configuration success message.

DCU receives the address configuration of first ammeter with after success message, can confirm that described first is electric Telogenesis work(configuration address.If after DCU broadcast transmission mailing address assignment messages, do not connect in preset duration The address configuration for receiving first ammeter matches somebody with somebody success message, then it is assumed that this described first ammeter is without success Configuration address, can re-broadcast transmission mailing address assignment messages, wherein carrying the of first ammeter One identifier and the first mailing address pair.The accuracy of address distribution can so be improved.It is being once multiple In the case of ammeter distribution mailing address, if wherein certain (or some) is not received by preset duration The address configuration success message of ammeter, then DCU think that (a little) ammeter does not have successful configuration address, again During broadcast transmission mailing address assignment messages, it is only necessary in the message carry should (a little) ammeter identifier with Mailing address pair.So not only improve the efficiency of address distribution but also can guarantee that accuracy.

As shown in Fig. 2 the handling process of ammeter can include the steps in the method：

Step 201, intelligence instrument receive the mailing address assignment messages of DCU broadcast transmissions, mailing address point Include the first identifier and the first mailing address pair with message, the first mailing address is DCU according to the first mark Know symbol to be distributed.

In force, DCU is broadcast to mailing address assignment messages after ammeter, and ammeter can then be received Then the mailing address assignment messages can be parsed, be obtained by the mailing address assignment messages that DCU sends The first identifier therein and the first mailing address are taken, to carry out subsequent treatment.

Step 202, when intelligence instrument determines the identifier that the first identifier is intelligence instrument, intelligence instrument is matched somebody with somebody Put the first mailing address.

In force, ammeter gets the first identifier and the first mailing address in mailing address assignment messages Afterwards, the identifier of the ammeter can be obtained, if the first identifier (consistent) identical with the identifier of the ammeter, Then the ammeter can be stored to the first mailing address, using the first mailing address as oneself (ammeter) Mailing address.If the first identifier in mailing address assignment messages is different from the identifier of the ammeter (no Unanimously), then the mailing address assignment messages can be abandoned.

Optionally, after intelligence instrument configuration successful, DCU can be notified, corresponding processing procedure can be as follows： Intelligence instrument sends address configuration success message to DCU.

In force, the first ammeter with the first identifier is successfully configured after the first mailing address, Ke Yixiang DCU sends address configuration success message, so that DCU accurately knows whether first ammeter is successfully configured with Address.If after DCU broadcast transmission mailing address assignment messages, not receiving address in preset duration and matching somebody with somebody Success message is put, then can re-broadcast transmission mailing address assignment messages.

Embodiments provide a kind of system of distribution mailing address, including main website, data centralized unit DCU and intelligence instrument, as shown in figure 4, in the system, being the process bag of intelligence instrument distribution mailing address Include the steps：

Step 401, main website send identifier notification message to DCU, and the identifier notification message includes First identifier.

Main website can be by identifier (i.e. the first identifier) addition of the intelligence instrument for needing to distribute mailing address To in identifier notification message, then the identifier notification message can be sent to corresponding DCU.Specifically Ground, main website know that the intelligence instrument is connected to the DCU, when main website determines that the intelligence instrument needs distribution logical During letter address, such as when the intelligence instrument has just added the system, DCU of the main website to the intelligence instrument connection Send identifier notification message, the identifier notification message includes the identifier of the intelligence instrument, i.e., the One identifier.

Certainly, main website once can also issue multiple identifiers to the DCU, so that the DCU is the plurality of The corresponding intelligence instrument of identifier, is respectively allocated mailing address.

DCU can be parsed to identifier notification message, obtain the first identifier, it is possible to will receive The first identifier stored.

Step 402, DCU receive the identifier notification message that main website sends, logical according to the identifier Know message, be that the first identifier distributes the first mailing address, and preserve the first identifier and the first mailing address It is right.

In force, it is the mailing address of ammeter distribution that can prestore in DCU, and can be remembered Mailing address and untapped mailing address that record has been used, to be allocated process.Ammeter is communicatedly Location can be represented with 8 bits.DCU is received after receiving the identifier notification message that main website sends, The identifier notification message is parsed, the first identifier is obtained, then can be prestored in DCU In mailing address, untapped mailing address is determined, in untapped mailing address, obtain first and communicate Address, and then the first mailing address can be distributed to the corresponding ammeter of the first identifier, it is possible to preserve mark Know symbol and mailing address pair, set up the corresponding relation of identifier and mailing address, such as shown in table 1.

Step 403, DCU broadcast transmission mailing address assignment messages, mailing address assignment messages include One identifier and the first mailing address pair.

In force, DCU is after the first ammeter with the first identifier configures the first mailing address, can be with By the first mailing address and the first identifier to being placed in mailing address assignment messages, then in the form of broadcasting It is sent to the ammeter being connected with the DCU.Can be entered using 485 communication protocols between DCU and ammeter Row communication.In practice, DCU can adopt Modbus lattice to the mailing address assignment messages that ammeter is broadcasted The message of the message, or form of formula.

Step 404, intelligence instrument receive the mailing address assignment messages of DCU broadcast transmissions, mailing address point Include the first identifier and the first mailing address pair with message.

In force, ammeter can receive the mailing address assignment messages of DCU broadcast transmissions, then can be right The mailing address assignment messages are parsed, and obtain the first identifier therein and the first mailing address, so as to Carry out subsequent treatment.

Step 405, when intelligence instrument determines the mark that the first identifier is itself (that is, described intelligence instrument) Fu Shi, the intelligence instrument configure the first mailing address.

In force, ammeter gets the first identifier and the first mailing address in mailing address assignment messages Afterwards, the identifier of the ammeter can be obtained, if the first identifier (consistent) identical with the identifier of the ammeter, Then the ammeter can be stored to the first mailing address, using the first mailing address as the mailing address of oneself. If the first identifier (inconsistent) different from the identifier of the ammeter, the mailing address can be abandoned and distributed Message.

In addition, the embodiment of the present invention is additionally provided based on the above-mentioned mailing address for intelligence instrument distribution, carry out The processing procedure of intelligence instrument data query, wherein, intelligence instrument can be intelligent electric meter, intellectual water meter or Intelligent gas meter etc..The present embodiment is illustrated so that intelligence instrument is as intelligent electric meter as an example, other situations with etc Seemingly.As shown in figure 5, the process of the intelligence instrument data query specifically may comprise steps of：

Step 501, DCU receive the first data query message that main website sends, in the first data query message Including the first identifier.

In force, can be provided with main website for inquiring about the application program of ammeter data, attendant can To open the application program, the ammeter (i.e. the first ammeter) for needing to inquire about ammeter data, point then can be selected Hit the first ammeter data query option, main website can then receive to should the first ammeter data query instruction, Then the first data query message can be sent to DCU, can carry in the first data query message this First identifier of one ammeter.Or, main website can be sent to DCU when default polling cycle is reached First data query message, the first data query message include the first identifier of first ammeter.

In addition, attendant can also select to need in above-mentioned application program to inquire about the area of ammeter data DCU, then clicks on ammeter data query option.Main website can then receive to should DCU ammeter data Query statement, then can obtain the mark of the DCU, so can according to the identifier for prestoring with The corresponding relation of the mark of DCU, it is determined that the identifier of the ammeter being connected with the DCU, then can be to this DCU sends the first data query message, and it is some that the first data query message includes being connected with the DCU The identifier of ammeter.Or, attendant can send one to DCU by main website and not carry identifier Data query message (the 3rd data query message can be referred to as), after DCU receives the 3rd data query message, Data query message can be sent to all ammeters being connected with DCU, so as to carry out ammeter data inquiry.
