Description of drawings
Fig. 1 carries out the method schematic diagram that active and standby plate data compare fast in the present embodiment;
Fig. 2 carries out the method schematic diagram that active and standby plate data compare fast in the specific embodiment.
Embodiment
Use identifying code to carry out the equipment that active and standby plate data compare fast, comprise main board and standby plate, main board comprises identifying code generation module and data distributing module; Standby plate comprises quick comparison module;
Described identifying code generation module is used for being divided into the main board data multinomial and distribute data item sign, for every data generate corresponding identifying code, and described identifying code is sent to the data distributing module; Is parity check code to every item number according to generating corresponding identifying code; Also comprise cyclic check code: the total length of data item identifier, Data Update number of times, described parity check code and these data according to following one or more generations of data; Also be used for when receiving new configuration data, the every data after upgrading generated corresponding identifying code, and described identifying code is sent to the data distributing module.
Described data distributing module is used for every item number certificate and corresponding identifying code are sent to standby plate; Also be used for every data after upgrading and corresponding identifying code are sent to standby plate.
Described quick comparison module is used for every identifying code content of comparison main board and standby plate when consistent, judges that promptly the main board data are identical with the standby plate data; When relatively every identifying code content of main board and standby plate is inequality, the data item identifier of the inconsistent identifying code correspondence of comparative result is notified to main board.
As shown in Figure 1, the method that the data of main board and standby plate are compared fast may further comprise the steps:
Specific embodiment:
In the specific embodiment, the main board data are divided into multinomial, and one the checking code table.Concrete composition field is as shown in table 1:
Table 1
The main board data are divided into when multinomial, can be according to different rules.For example, according to different operational orders, different data type or the like is not listed among the present invention one by one.
Total length than an item number certificate, the bit that the parity check code that generates according to these data takies, number less (can be 4 bytes at most), a twin check sign indicating number can learn whether these data are identical when making the data comparison like this, has saved more every data consumed time and data processing amount.Cyclic check code further guarantees the accurate of check code as the secondary check code, improves data accuracy relatively.
As shown in Figure 2, the method that in the specific embodiment data of main board and standby plate is compared fast comprises:
During the main board initialization, multinomial when the content of checking the identifying code of preserving is empty according to the data on the main board are divided into, and generate identifying code respectively, be kept in the checking code table.When the content of the identifying code of check preserving be empty, recomputate the cyclic check code of every item number certificate, if the cyclic check code that calculates and preserved inconsistent, then regenerate the identifying code of every data.
When step 202, the tension management equipment of main board issued quick comparison command, perhaps, periodically when main board was initiated quick comparison of request, main board was sent to standby plate with the identifying code of every data to standby plate;
When adopting above-mentioned identifying code sheet format, main board is sent to standby plate with every item number certificate and this checking code table of having write down above-mentioned each field information of every data.
In the said method, main board also needs the renewal to identifying code on the standby plate.When the tension management equipment of main board issues new data, main board upgrades every data and corresponding identifying code after finishing data configuration, and with new configuration data and the identifying code after upgrading be synchronized to standby plate, keep the consistency of data on main board and the standby plate.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
