Embodiment
Check meter first and in the infrared copying instrument database, set up the electric energy meter data in the copy same table case of returning related.Can by the electric energy meter in the infrared copying instrument active searching table case, check meter by table number later on.
Check meter first
Infrared copying instrument transmission broadcasting is checked meter, and (what is called is broadcasted the order of checking meter that the order of checking meter refers to that all ammeters send in the his-and-hers watches case in order, rather than send for certain piece ammeter, namely do not contain single table identity code, all receive the ammeter of broadcasting the order of checking meter and all need uploading data), comprise two parameters in the order: (the so-called time-delay factor is the duration factor that the ammeter computation delay used during the time for electric energy meter number and the time-delay factor in the table case, delay time is the integral multiple of the time-delay factor, the difference of different ammeter delay times also is the integral multiple of the time-delay factor, clash when avoiding different ammeter reported data, the time-delay factor should be greater than single table used time of uploading data).The random code that every electric energy meter produces with self random code maker 3 is divided by electric energy meter number in the twice table case, and the remainder that obtains multiply by the time-delay factor as the delay time that reports of electric energy meter.The delay time of each electric energy meter has arrived, electric energy meter will be given infrared copying instrument data upload by infrared communication circuit automatically, infrared copying instrument can be given an affirmation to the data received, receive after this table confirmation electric energy meter next bar check meter order can be not again before coming automatically uploading data to infrared copying instrument, other do not receive that the electric energy meter of this table confirmation can be collected specifically by the affirmation information that infrared copying instrument returns to other tables and copy that what tables are not are not correctly copied and accepted by infrared copying instrument in addition, time-delay all finishes when the first round, the electric energy meter of not receiving this table confirmation will be according to not copying and accepting successfully the electric energy meter number, the time-delay factor and self random code recomputate delay time, and when delay time arrives again, automatically report electric energy meter information to infrared copying instrument, and initiatively finish this infrared copying instrument the collection of self is copied.
Generally speaking, infrared copying instrument sends broadcasts the order of checking meter, the electric energy meter two-wheeled reports the electric energy meter information just can be all electric energy meter information acquisitions success automatically, if infrared copying instrument does not receive the reported data of all electric energy meters after command expiration is checked meter in broadcasting, infrared copying instrument will by broadcasting the continuous order of copying, continue to wait for the electric energy meter reporting information.Electric energy meter receive continuous copy order after, the electric energy meter that receives the infrared copying instrument confirmation is no longer delayed time and is reported operation, does not report successful electric energy meter to continue to report ammeter information.
Infrared copying instrument to receive every effective electric energy meter reporting information, return and report confirmation, and the effective information number that utilizes counter accumulative total to receive, the output valve of counter is the number that meter-copy device successfully receives the ammeter reporting information, if the effective information number reaches electric energy meter number in the table case, infrared copying instrument can finish immediately this and checks meter so.Check meter finish after infrared copying instrument can also calculate according to the electrical parameter in system time and the last item electric energy meter information table case number (CN) (being used for next centralized automatic meter-reading) and these all electric energy meter information storage of copying and accepting to database (record of every electric energy meter), and according to every LSN that is recorded in the database, a closed-loop data chain set up in these records, the closed-loop data chain is the data chain that is joined end to end and formed by the storage address of all ammeter datas in the meter-copy device storer in the same table case, and this Data-Link bar shaped closed loop becomes.
The processing of electric energy meter random delay and conflict:
If it is the same having electric energy meter to produce delay time, the data that they send out may will be washed out.Electric energy meter can automatically detect outside infrared signal, has sent out first if detected an electric energy meter, and other electric energy meter can stop transmission information, etc. there being the free time more than 150 milliseconds just can send out (even delay time has arrived) on the infrared channel.
The chance that each electric energy meter has two-wheeled automatically to upload, there is not successful electric energy meter for crossing on the first round, electric energy meter is taken turns again uploading data second, for in the two-wheeled collection is copied, all copy less than electric energy meter, can adopt continuous order of copying to go to check meter, the broadcasting of infrared copying instrument is continuous copies order and gets off, can tell electric energy meter always total how many piece electric energy meters to continue and copy, for the electric energy meter of having copied uploading data not just, there is not the electric energy meter of uploading data to upload by automatic time delay.
Non-ly check meter first
Infrared copying instrument sends broadcasts the order of checking meter, and after receiving first electric energy meter reporting information, extract the electric energy meter identity code, in database, search this identity code corresponding data chain and table case number (CN), infrared copying instrument can extract identity code corresponding in the same table case Data-Link successively after finding Data-Link, initiatively check meter by identity code, when initiatively checking meter, the identity code that contains an ammeter in each order of checking meter, although all ammeters can both receive this order in the table case, but only receive the ammeter uploading data just that contains self identity code, need not again passive wait.Other the operation with check meter first identical.Because at this moment infrared copying instrument is initiatively to go to copy, taken the channel (not having 150 milliseconds of idle channels) of whole infrared communication, even if ammeter time-delay has at random been arrived, also can not upload.
