Description

A kind of disposal route that flexibly can power distributing meter stipulations for electricity meter-reading

Technical field

The present invention relates to low-voltage collecting meter reading technical field.

Background technology

At present, in the time building low-voltage collecting meter reading system, due to the problem of the ammeter manufacturer of user's side, ammeter production time, ammeter Type-Inconsistencies, cause centralized meter-reading system need to gather the stipulations of ammeter various, although there is the device that can gather multiple producer ammeter at present, but the disposal route of this device is little in flexibility ratio aspect the changeable stipulations of reply, be not easy to configuration management, ammeter stipulations region are relied on large, is unfavorable for deployment, the propagation and employment of device.

Summary of the invention

Configurable ammeter stipulations storehouse is set up in utilization of the present invention, realizes collection and copies the stipulations that can configure each ammeter in process, will strengthen the flexibility ratio configuring and adapt to intensity, adopts the collection copy device of the realization of the method to dispose simple, to be easy to popularization object by reaching.

To achieve these goals, the invention provides following technical scheme.

Disposal route that flexibly can power distributing meter stipulations for electricity meter-reading, the inventive method is as follows,

(1) analyze the characteristic item of all kinds of ammeter stipulations and the template of ammeter data collection and parsing, in software database, set up the stipulations storehouse of ammeter data processing;

(2) in software database, set up ammeter archives, and specify in the stipulations that in stipulations storehouse, ammeter adopts, the mapping of setting up ammeter archives and stipulations storehouse according to occurrence simultaneously;

(3) in the time will gathering ammeter A data, process the acquisition that generates this ammeter according to the acquisition module in indication stipulations storehouse in ammeter A archives, when after ammeter return data, first by the template processing of normally returning of ammeter A, if process unsuccessfully again according to A extremely return to template processing, if or failure mate parsing according to stipulations storehouse.

Effect of the present invention is: configurable ammeter stipulations storehouse is set up in utilization of the present invention, realize collection and copy the stipulations that can configure each ammeter in process, to strengthen flexibility ratio and the adaptation intensity of configuration, and adopt the collection copy device that the method realizes to dispose simple, to be easy to popularization object by reaching.

Fig. 1 utilizes this disposal route to realize the schematic diagram of checking meter.

Embodiment

Below in conjunction with drawings and Examples, the present invention is described in more detail.

Disposal route that flexibly can power distributing meter stipulations for electricity meter-reading, the inventive method is as follows,

(1) analyze the characteristic item of all kinds of ammeter stipulations and the template of ammeter data collection and parsing, in software database, set up the stipulations storehouse of ammeter data processing;

(2) in software database, set up ammeter archives, and specify in the stipulations that in stipulations storehouse, ammeter adopts, the mapping of setting up ammeter archives and stipulations storehouse according to occurrence simultaneously;

(3) in the time will gathering ammeter A data, process the acquisition that generates this ammeter according to the acquisition module in indication stipulations storehouse in ammeter A archives, when after ammeter return data, first by the template processing of normally returning of ammeter A, if process unsuccessfully again according to A extremely return to template processing, if or failure mate parsing according to stipulations storehouse

As shown in Figure 1, method of the present invention is as follows:

(1) set up ammeter stipulations storehouse;

Set up stipulations storehouse, first analyze the characteristic item of ammeter stipulations:

In coding, every value format analysis processing is " start bit, length, value ", i.e. " sp, len, val ".If multinomial value is expressed as " (sp, len, val), (sp, len, val) ... (sp, len, val) ".Wherein sp (start bit) represents the relative start bit of this processing domain, and len (length) represents the length of this processing domain, and val (value) represents the value in this territory.

As: condition code is with 0x68 beginning, with 0x16 ending, is specifically expressed as (0,1,68) (1,1,16).

Check code is that position is the 2nd reciprocal, and length 1 byte, adopts cumulative mode, concrete represent (2,1,0), and its intermediate value is the verification mode that 0 expression adopts.

Address code is that reference position is the 2nd, and length is 6 bytes, is specifically expressed as (1,6,000000000000).

Note: relatively start bit refers to that start bit can calculate (start several since 0) from the outset, also can calculate from end (reciprocal is negative, from-1), and the computing formula of actual initial place value is:

Actual reference position=message total length+start bit relatively.

Secondly analyze the processing of each data item of ammeter:

Sequence number	Definition	Code name
			?	So-called Regularia	RuleDll
?	Type	Type
			?	Data acquisition board	GetCmd
?	Normal response template	SuccessReturnCmd
			?	Exception response template	FailReturnCode
?	Normal response data field	SuccessDataArea
			?	Exception response data item	FailDataArea
?	Normal response data field is described	SuccessDataDetail
			?	Exception response data field is described	FailDataDetail

The processing format of data field is " start bit, length, value ", i.e. " sp, len, val ".If multinomial value is expressed as " (sp, len, val), (sp, len, val) ... (sp, len, val) ".Wherein sp (start bit) represents the relative start bit of this processing domain, and len (length) represents the length of this processing domain, and val (value) represents the value in this territory.

Data field describe processing format be " valDetail, valDetail ..., valDetail ", this processing is corresponding with the value of data field.

(2) set up the mapping in ammeter and stipulations storehouse, realize the corresponding a set of stipulations of an ammeter.

(3) in the time will gathering ammeter data, according to the stipulations storehouse of indication in ammeter archives, find the acquisition module of the data item that will gather, by replacing after the electric meter address in acquisition module, revise again the check bit of acquisition, so just realized the acquisition that changes these data of ammeter.After order is returned, first resolve by the parsing template of normal return data, if resolve unsuccessfully, resolve by the parsing template of extremely returning.

Example:

In certain centralized meter-reading system, ammeter archives and stipulations are as follows:

(1) ammeter archives:

Sequence number	Electric meter address	The stipulations that adopt
			1	592700102000	Rule1
2	592700102000	Rule1
			3	592700102000	Rule2

(2) stipulations characteristic item

Stipulations storehouse numbering	Condition code	Address code	Control code length code	Check code
					Rule1	(0,1,68),(-1,1,16)	(1,6,00000000000)	(8,1,00)(9,1,00)	(-1,1,00)
Rule2	(0,1,68),(-1,1,16)	(1,6,00000000000)	(8,1,00)(9,1,00)	(-1,1,00)

(3) stipulations subitem

A. gather electric weight

Sequence number	Definition	Code name
			?	Subitem gathers	Electric weight
?	So-called Regularia	Rule1
			?	Type	33333333
?	Data acquisition board	68522700102000681104333333335A16
			?	Normal response template	685227001020006891083333333357363433D216
?	Exception response template	6859270010200068D101378916
			?	Normal response data field	14,4,2
?	Exception response data item	14,1,0
			?	Normal response data field is described	Forward total electric weight of gaining merit
?	Exception response data field is described	?
