Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to accompanying drawing of the embodiment of the present invention, Further clear, complete description is done to the technical scheme in the embodiment of the present invention, it is clear that described embodiment is the present invention One kind of embodiment, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not having The every other embodiment obtained under the premise of creative work is made, belongs to the scope of protection of the invention.
Whole archives are ranked up by the first step, terminal with main website according to table address size.In power information acquisition system, The address of terminal and electric energy meter is the compressed code that length is 6 bytes, and terminal and main website will be based on quick sorting algorithm and complete The ascending order arrangement of both archive informations, obtains main website side ascending order set M1, end side ascending order set M2.After sequence is completed, terminal Side archives carry out piecemeal (N takes even number and N can optimize according to taiwan area size) by size N, i.e., per the division of N block electric energy table address For one group, it is assumed that be divided into n groups altogether, represent as follows:
Because same taiwan area electric energy meter address high byte is consistent, if M2Middle electric energy meter number can not be evenly divisible by N, i.e., n-th group is not During the N number of address of foot, address space left is that the address that this TV station regional address high byte low byte is full 0 replaces with high byte, ensures packet Each packet contains N number of data after completing.As shown in Figure 1.
Second step, end side archives are grouped and calculate packet checks value.After packet is completed, end side calculates M2Each point The check value of group, ultimately form terminal file verification value set
C={ c1,c2,L,cn}.
Check value ciThe calculating of (1≤i≤n) is divided into two steps:
(1) N number of address step-by-step XOR obtains the full information summary I of this packet in each packetbit_i(48bit).Due to same The affiliated electric energy table address high byte of one terminal is basically identical, then the I that full information can be made a summarybit_iThe 00H of high byte is deleted, so as to Obtain compressing full information summary Ibit_i_com(40bit)。
(2) I obtained to upper stepbit_i_comCRC-16 check codes are carried out, obtain check bit Cbit_i;Check bit is attached to After compressing full information summary, 56bit check value c of the result as this packet is obtainedi
3rd step, the check value that main website is sent using end side carry out archives contrast, determine archives difference set.It can be divided into The following steps:
(1) terminal sends C and packet size N to main website.Main website is carried out solving parsing and judged based on check bit each to C ciWhether transmit correctly, if each ciAll transmission is correct, then removing check bit successively can obtain compressing full information summary set B ={ Ibit_1_com,Ibit_2_com,L,Ibit_n_comAnd entrance step (2);Otherwise the packet numbering of check errors is recorded, and to end Side sends repeat request, it is desirable to is retransmitted the grouping information of error of transmission;Until receive correct.
(2) main website is to itself archive information ordered set M1Computing is carried out, and operation result and terminal file are compressed entirely Informative abstract set B is compared, and process is as follows:
1. take M1The { 1,2 ..., N } altogether N number of power meter group into archives set Dtemp, and calculated according to second step check value The XOR that step (1) calculates N number of address is worth to this I being groupedbit_temp_com
2. by Ibit_temp_comContrasted with element in set B, as shown in Figure 2.
If
Ibit_temp_com∈ B, that is, i be present and cause Ibit_temp_com=Ibit_i_com
Then illustrate M1{ 1,2 ..., N } block table be already present in terminal file, record packet index value i now To indifference set R;And shifting N obtains new electric energy meter packet after being grouped electric energy meter sequence number, that is, takes M1{ (N+1), (N ... ,+2) 2N } individual power meter group is into new archive set DtempAnd calculate new Ibit_temp_com(only need afterwards with B Ibit_i+1_comAnd its value contrast afterwards).
If
Then record DtempThe 1st electric energy meter to difference set X;And obtain new electricity by moving 1 after packet electric energy meter sequence number Energy table packet, that is, take M1{ 2,3 .., (N+1) } individual power meter group into new archive set DtempAnd calculate new Ibit_temp_com (I corresponding with maximum maxR in R is needed afterwardsbit_maxR_comValue contrast afterwards).
3. by that analogy, repeat step is 2. until M1In electric energy meter be all fetched into.
4th step, by above-mentioned steps, electric energy meter indifference set R and difference set X are obtained, need not if X is sky It is synchronous;If X is not sky, main website need to only issue in X set index value in corresponding electric energy meter archives and R.End side parsing master Station issues archives renewal message, and according to information in non-difference set R, the reservation to same files information block and difference can be achieved The deletion of archive information packet;According to information in difference set X, the renewal of difference file can be achieved, as shown in Figure 3.
Archives synchronizing process only issues difference table information and set R it can be seen from synchronizing process.The archives that compare are complete Subordinate's forwarding method, this scheme greatly reduces the archives amount of issuing, and main website and terminal file difference are smaller, and set X is also just smaller, The advantage of this scheme is also more obvious;And set R only includes grouping serial number, the information content for now transmitting non-difference set is also minimum; On the other hand, when calculating check value, same taiwan area electric energy meter address high byte identical characteristic is taken full advantage of, check value is carried out Compression, reduce further upload data volume, improves efficiency.Result of field running shows, carries archives synchronous method tool There is greater efficiency, and implementation complexity is relatively low, has preferable practical application and promotional value.
Although embodiments herein has been shown and described above, it is to be understood that above-described embodiment is example Property, it is impossible to the limitation to the application is interpreted as, one of ordinary skill in the art within the scope of application can be to above-mentioned Embodiment is changed, changed, replacing and modification.
