Fig. 4 is the exemplary interaction figure of meter register method implementation process 400 according to an embodiment of the invention.Wherein, treat that the gauging table of copy reading is electric energy meter, be called for short ammeter, in the diagram, only depict two pieces of ammeters, replace with indicating two lines of " ammeter " two under word rectangle frame, also depict the website that this two pieces of ammeters are corresponding in the drawings, replace with indicating two lines of " website " two under word rectangle frame, corresponding relation therebetween can finding out from signaling alternately, in order to illustrate conveniently, select the flow process of checking meter of two pieces of ammeters marked to do in Fig. 4 to illustrate typically, and these two pieces of ammeters are distinguished with 1 and 2 at message corresponding in flow process of checking meter, should be understood that, in real system, can comprise more than two websites, at least one piece of ammeter is comprised under each website.Described ammeter can be concentrate 485 ammeters settled, and also can be the carrier wave meter of scattered resettlement.Shown embodiment describes a certain subsystem under the power user power consumption information acquisition system Zhong Yigetai district running on State Grid Corporation of China in detail, and when using power wire broadband carrier communication system to communicate, the execution flow process of this meter register method.In the present embodiment, the main website end of described subsystem is a concentrator, and its communication module is CCO, and described CCO is hardware module.Each in the multiple collector connected by line of electric force under concentrator and multiple carrier wave meter is provided with a Local Communication Module STA, and described STA is hardware module.Flow process of checking meter described in the embodiment of the present invention refers to concentrator and initiatively issues an order of checking meter, through CCO, described in check meter the corresponding STA of order and corresponding ammeter, finally return the corresponding process reporting message of order of checking meter to this by CCO, or CCO initiatively permits to concentrator request, secure permission or check meter after order, issue meter reading instruction to STA, finally returned by CCO and corresponding to this meter reading instruction report message to the process of concentrator.It should be noted that, owing to checking meter in the embodiment of the present invention, order and meter reading instruction all support continuous transmission, and ammeter is numerous under power user power consumption information acquisition system Zhong Yigetai district, flow process of checking meter is again the day to day operation in system, the multiple flow process of checking meter of real time execution in system, in the step of the present embodiment except situation about clearly stating, all without clear and definite sequencing between step.

Step 402, check meter in the cycle at one, concentrator sends at least two orders of checking meter to trigger flow process of checking meter to CCO continuously, carries one piece and treat that the mark of ammeter is copied in copy reading described in each in order of checking meter.

Concrete, described in treat that the mark of copy reading ammeter is treat the address information of copy reading ammeter in the present embodiment.

Describedly treating that copy reading ammeter can be 485 tables, also can be carrier wave meter.

Wherein, it should be noted that, continuous in the present embodiment, namely concentrator sends one for after the order of checking meter of certain ammeter, can not wait for that CCO returns and message is reported to this order of checking meter, just can continue to send order of checking meter to another ammeter to CCO, namely send order of checking meter continuously, this another ammeter can in kilowatt meter reading-out system same STA corresponding to certain ammeter described, also can in kilowatt meter reading-out system another STA corresponding.

In another embodiment, concentrator employing is carried on the frame of many orders of checking meter the mode in a piece of news, described many orders of checking meter are sent to CCO, do not change frame structure, can check meter in the cycle at one equally, issue many orders of checking meter, every bar is checked meter, and order is all corresponding different treats copy reading ammeter.

On the other hand, it should be noted that, in the embodiment of the present invention, described in the cycle of checking meter refers to and sends many orders of checking meter continuously from described concentrator to described CCO, until described concentrator receives the time course that first bar reports message after sending described many orders of checking meter continuously.Further, concentrator receives after described first bar reports message, then again can issue new order of checking meter continuously, and issuing new order of checking meter continuously is then that the next one is checked meter the beginning in cycle.Be understandable that, in the present system, check meter in the cycle at one, concentrator, before receiving described first bar and reporting message, can issue many orders of checking meter.

Due in most remote intelligent meter recording system, there are two kinds of trigger flow modes of checking meter, namely initiatively permitted, to initiate to check meter to concentrator request by CCO; Or initiatively issue order of checking meter to CCO by concentrator.On the other hand, because under a Ge Tai district, ammeter is numerous, the information real-time change because of electricity consumption again of ammeter, therefore, in remote intelligent meter recording system, communication interaction process of checking meter is real time execution substantially.And in the embodiment of the present invention, adopt and initiatively issue order of checking meter to the triggering mode of checking meter of CCO by concentrator.Therefore, optionally, before implementation step 402, initiatively permitted to concentrator request the process of checking meter that triggered first to perform following steps by CCO if power user power consumption information acquisition system is being run:

Step 401a, concentrator send to CCO and cease and desist order, and instruction CCO stops the process of checking meter of current operation.

After step 401b, CCO receive ceasing and desisting order of concentrator, stop the process of checking meter of current operation, send a confirmation message to concentrator, so that at least two orders of checking meter are to trigger new flow process of checking meter described in concentrator transmission.

Step 401a and step 401b ensure that the meter register method in the embodiment of the present invention can correctly and successfully be triggered by concentrator.

It should be noted that, it will be appreciated by those skilled in the art that, the reception that the process of checking meter that CCO runs comprises CCO check meter order, process check meter order, management meter reading instruction, send meter reading instruction, receive feedback message, send and report the processes such as message, wherein said process order of checking meter comprises buffer memory and to check meter order, parsing check meter order, according to checking meter, order generates the process such as meter reading instruction, described management meter reading instruction comprises the processes such as buffer memory meter reading instruction, and the embodiment of the present invention does not limit.

Concrete, in the present embodiment, the frame format of the interactive command between concentrator and CCO is based on Q/GDW376.2-2009 " power user power consumption information acquisition system communication protocol: concentrator Local Communication Module interface protocol ".

It will be appreciated by those skilled in the art that, enterprises different in this area and producer usually adopt different agreements, based on the agreement that State Grid Corporation of China formulates in the present embodiment.But, the standard that the interactive command frame format between concentrator and CCO is followed or agreement, and to for realizing step 402 and the expansion may done the interactive command frame format between concentrator and CCO or improvement, the embodiment of the present invention does not limit.

Optionally, the mark of the STA module that ammeter to be copied is corresponding described in can also carrying in order of checking meter described in each can be specifically the MAC Address of the STA module that ammeter to be copied is corresponding, and selection and the expansion of its frame format repeat no more in the present embodiment.

Step 404, CCO receive described at least two orders of checking meter that concentrator sends continuously, according to the address information treating copy reading ammeter of carrying in order of checking meter described in each, continuously to the different STA of correspondence, CCO treats that STA corresponding to copy reading ammeter sends meter reading instruction by bandwidth carrier line of electric force, the order of checking meter that the corresponding CCO of meter reading instruction described in every bar receives, carries the physical MAC address of corresponding STA and treats the address of copy reading ammeter in described meter reading instruction frame.

Wherein, concrete, after CCO receives the order of checking meter of concentrator, treat that the address information of ammeter is copied in copy reading according to what carry in described order of checking meter, the mapping table of the physical MAC address of the STA that the electric meter address stored in CCO is corresponding with ammeter, find and treat that the physical MAC address of STA corresponding to ammeter is copied in copy reading, described in treat that copy reading copies that STA management corresponding to ammeter is corresponding with STA treats copy reading ammeter, thus meter reading instruction can be sent to correct STA by guarantee CCO.If described in check meter to have carried in order described in treat the MAC Address of the STA module that copy reading ammeter is corresponding, then without the need to tabling look-up.

Concrete, in the present embodiment, certain enterprise communication standard followed by the frame structure of the meter reading instruction that the communication between CCO from different STA and CCO send continuously to different STA.It should be noted that, be similar to step 401a, 401b and step 402, the present invention does not limit the frame format communicated between CCO and STA involved in the embodiment of the present invention and the possible concrete expansion made for certain agreement.

Wherein, CCO continuously to the different STA of correspondence on line of electric force when the STA corresponding to copy reading ammeter sends meter reading instruction, can phase place be divided, also can regardless of phase place, in the present embodiment, CCO sends meter reading instruction regardless of phase place on line of electric force.

In addition, it will be understood by those skilled in the art that in remote intelligent meter recording system, CCO issues meter reading instruction to the STA treated corresponding to copy reading ammeter after receiving the order of checking meter that concentrator issues.Therefore similar, in the meter register method of the embodiment of the present invention, CCO can issue meter reading instruction to the STA of correspondence in the process of many meter reading instruction receiving concentrator.Specifically refer to: after CCO receives the order of checking meter that Article 1 concentrator issues, just can start to process Article 1 to check meter order, then check meter to Article 1 and treat that the STA that copy reading ammeter is corresponding issues meter reading instruction indicated by order, and Article 1 check meter order issue meter reading instruction to the STA of correspondence time, also can receive the follow-up order of checking meter that concentrator issues, issue meter reading instruction without the need to the STA started again to correspondence after whole orders of checking meter that wait-receiving mode concentrator issues.Therefore, step 402 starts before step 404, but step 402 and step 404 have lap in time.Further, do not limit order when CCO sends meter reading instruction continuously in the embodiment of the present invention, namely CCO is when sending meter reading instruction, do not need to consider to receive concentrator check meter order time the priority of respectively ordering.

Wherein, it should be noted that, continuous described in the present embodiment, on the one hand, be presented as CCO can one connect a ground and receive two or more the order of checking meter that concentrator sends, and it to be processed; On the other hand, also be presented as after sending a meter reading instruction to certain STA, can not wait for that this STA returns and message is reported to this meter reading instruction, just can continue to send another meter reading instruction to another STA, namely CCO can check meter according to the concentrator received order, meter reading instruction is sent continuously to different STA, also can referred to as CCO to STA transmitted in parallel meter reading instruction.

But in existing remote intelligent meter recording system, STA is also arranged on collector, often has polylith ammeter, and be still that 485 buses are connected between collector with ammeter under collector, and the STA that polylith ammeter correspondence one is identical.When CCO receive order of checking meter in have two or more to point to same STA under different ammeter time, the subsequent step of flow process of checking meter can perform existing serial meter register method.Be specially after CCO sends a meter reading instruction to this STA, must wait for this STA return to this meter reading instruction report message after, could continue to send another meter reading instruction to this STA.On the other hand, the subsequent step of flow process of checking meter also can perform expansion scheme, namely two or more meter reading instruction of the different ammeters pointed under same STA carries by CCO in same message, sends to the STA that meter reading instruction is corresponding, then is resolved by STA and be distributed to each corresponding ammeter.

In order to ensure that CCO can completing steps 404, and correctly can issue meter reading instruction to the STA of correspondence, the process of checking meter can be carried out smoothly, and in embodiments of the present invention, CCO adopts a kind of disposal route.For convenience of description, the disposal route received for CCO after the order of checking meter of a concentrator is described, and according to following method, CCO processes each concentrator received order of checking meter.It should be noted that, here just one illustrate, the embodiment of the present invention do not limit CCO receive the order of checking meter of concentrator after disposal route.

Step 501, CCO, according to the mapping table of checking meter in order inquiry CCO of receive concentrator, obtain this concentrator and check meter and treat the MAC Address of the STA corresponding to address of copy reading ammeter in order.

Step 502, according to MAC Address, CCO solicited message corresponding to order of this being checked meter is kept in one section of buffer memory of CCO, and described buffer memory is called concurrent pond, and each bar that the concentrator received for temporary CCO sends continuously is checked meter the solicited message of order.

Concrete, described request information can be order of checking meter, and also can be the information gone out according to command analysis of checking meter, and also can be the meter reading instruction generated according to order of checking meter, the embodiment of the present invention limit.In the present embodiment, solicited message is the meter reading instruction generated according to order of checking meter.

If there is not solicited message therewith in step 503 buffer memory to carry the solicited message of identical MAC Address, then CCO is according to solicited message, and the STA to correspondence sends meter reading instruction; If there are other solicited messages that identical MAC Address is carried in the request of checking meter of bar therewith in buffer memory, then CCO waits for that other solicited messages described are all disposed, then sends described meter reading instruction to the STA of correspondence.

Wherein, concrete, described in described wait, other solicited messages are all disposed, STA again to correspondence sends meter reading instruction, CCO can be referred to other solicited messages described, complete existing serial one by one and to check meter process, then send described meter reading instruction to the STA of correspondence; Or, can refer to after described meter reading instruction comes meter reading instruction corresponding to other solicited messages described by CCO, send to STA as a piece of news.

Concrete, in above-mentioned disposal route, step 502 adopts following concrete implementation method in the present embodiment.Wherein, concurrent pond can comprise longitudinal buffer memory and horizontal buffer memory.Longitudinal storage space of buffer memory and the storage space of horizontal buffer memory all uncertain before request write of checking meter, only limit when completely namely buffer memory is completely write full in concurrent pond, the storage space of longitudinal buffer memory and the storage space sum of horizontal buffer memory equal the storage space in concurrent pond.Further, the concrete storage size of the embodiment of the present invention to concurrent pond does not limit, and in the present embodiment, the capacity in concurrent pond is for can hold 64 requests of checking meter altogether.

Longitudinal buffer memory is made up of concurrent node, and for storing the request of checking meter of carrying different MAC Address, a concurrent node stores a request of checking meter, and the meter reading instruction of request of the checking meter correspondence stored in different concurrent node can by CCO transmitted in parallel to corresponding STA; Horizontal buffer memory then regards the horizontal queue after each concurrent node as, for storing the request of checking meter of carrying identical MAC Address, horizontal queue refers to the storage space of the request of checking meter of identical MAC Address, the tail of the queue of horizontal queue refers to not write in storage space the part of the request of checking meter, for the meter reading instruction that the request of checking meter in horizontal buffer memory is corresponding, CCO can according to existing mode serial processing, or by meter reading instruction corresponding for the request of checking meter in horizontal queue, be carried in a piece of news by the reception order of the order of checking meter of its correspondence and issue.

CCO identifies the MAC Address of carrying in this request of checking meter, if the MAC Address of carrying in this request of checking meter, all not identical with the MAC Address entrained by asking of checking meter write in described buffer memory, or the Article 1 request of checking meter write in described buffer memory, then a concurrent node of the longitudinal buffer memory of request write of this being checked meter; If the MAC Address of carrying in this request of checking meter, identical with one that has write in the described buffer memory MAC Address entrained by asking of checking meter, then the horizontal queue tail of the queue of the concurrent node of the request of checking meter of identical MAC Address is carried with it in request write of this being checked meter.

It should be noted that, in implementation method concrete above, the longitudinal buffer memory mentioned and horizontal buffer memory only represent a kind of functional differentiation, can not think that concurrent pond is made up of vertical and horizontal both direction, can not the form in therefore limiting concurrent pond, concurrent pond form is not limited in the embodiment of the present invention.In the present embodiment, concurrent pond is one section of buffer memory, and its data structure can be chained list, stack, queue etc., and the present invention does not limit.
