Embodiment two:
Fig. 3 is the flow chart of magnetic data method of reseptance provided by Embodiment 2 of the present invention, specifically includes step S201 extremely
S205, details are as follows:
S201, to reading when the value of first row of the previous frame data in preset line number threshold range is read line by line
It takes.
In embodiments of the present invention, line number threshold value is an empirical value, and empirical value acquirement is excessive and too small all improper,
This is because if line number threshold value obtain it is excessive, when losing line number amount and being not above line number threshold value, on a large scale to losing capable progress
Detection will increase the calculation amount of system；If line number threshold value obtain it is too small, lose line number amount it is many when, such as lose line number amount and be more than
Line number threshold value cannot detect actual to lose line number amount due to can only detecting to losing row to small range.
As an embodiment of the present invention, line number threshold value can take 20, correspondingly, exist to the previous frame data of working as of reading
The value of first row in preset line number threshold range is read line by line, can be in reading when previous frame data inverse 20

When the value of the first row of reading is judged, if the value of the first row is 1, then it represents that opened from this line that the first train value is 1
Begin, until the last line of this current frame data, this partial data belongs to the data of next frame, is due to working as
The losing row of previous frame data and cause to be read in advance.
Specifically, it is 1 position of the row according to the value of first row, counts from the row up to this current frame data
Total line number of last line, as when previous frame data specifically lose line number amount.
S203, basis lose line number amount and calculate the data volume for working as former frame.
Specifically, it can subtract that lose line number that line number measures be to work as former frame reality with total line number of each frame data
Data volume.
For example, it is assumed that losing line number amount when former frame is 6 rows, since total line number of each frame data is 1386 as defined in agreement
Row, then when the actual data volume line number of former frame is 1380 rows.
S204, algorithm process is carried out to the data when former frame.

Specifically, line number amount is lost according to when former frame, calculates the memory block first address of next frame data, i.e., to original
The memory block first address of next frame data carries out biased forwards, and offset is to lose line number amount, while counting again according to line number amount is lost
The data volume of next frame data to be read, total line number of each frame data subtract that lose line number that line number measures be to continue
The data volume of the next frame data taken.
For example, it is assumed that when the memory block first address of former frame is 0x10000000, the memory address where every data line
It is assumed to be line by line plus 1, since total line number of each frame data is 1386 rows as defined in agreement, then original next frame data is interior
Counterfoil first address is 0x1000056A, it is assumed that losing line number amount when former frame is 6 rows, then the first ground of the memory block of practical next frame data
Location needs 6 row of biased forwards, i.e. 0x10000564, and the data volume that the next frame data read are actually needed is 1380 rows.
For the present embodiment that gets across, now it is illustrated below.
As shown in figure 4, addr1 is the memory block first address of the first frame data, addr2 is the memory block of former second frame data
First address.91 rows of the first frame data occur losing row phenomenon, and the first row of the second frame is caused to advance to the last line of first frame
It is received.
It is read line by line by the value of the first row of last 20 row to the first frame data, it is found that last line first
The value of column is 1, therefore judge first frame loses line number amount for 1 row, is according to the line number meter calculating actual quantity of first frame is lost
1385 rows, the i.e. part that A is indicated in Fig. 4.
Biased forwards a line, i.e. Fig. 4 are needed according to losing line number amount and further calculate out the memory block first address of the second frame simultaneously
The data volume of position represented by middle addr2 ' and the second frame data to be read is 1385 rows, the i.e. portion that B is indicated in Fig. 4
