Embodiment 2

[0034] image 3 It is a flow chart of the magnetic data receiving method provided in Embodiment 2 of the present invention, specifically including steps S201 to S205, detailed as follows:

[0035] S201. Read the values ​​of the first column of the read current frame of data within a preset row number threshold range row by row.

[0036] In the embodiment of the present invention, the row number threshold is an empirical value, and it is not appropriate to take the empirical value too large or too small, because if the row number threshold is too large, when the number of lost rows does not exceed the row number threshold , detecting the missing rows in a large range will increase the amount of calculation of the system; if the row number threshold is too small, when the number of missing rows is large, for example, the number of missing rows exceeds the row number threshold, since only a small range of missing rows can be detected Rows are detected, so the actual number of mi...

Abstract

The invention relates to the financial technology field, and provides a magnetic data receiving method and a magnetic data receiving device. The problem of the data processing error caused by the magnetic data row loss during the receiving of the magnetic data can be solved. The magnetic data receiving method is characterized in that the data row loss detection of the read current frame of data can be carried out, and the lost data row number can be acquired; the data position can be determined again according to the lost data row number; the next frame of data can be read according to the data position. The data row loss detection of the read current frame of data can be carried out, and the lost data row number can be acquired, and then the data position can be determined again according to the lost data row number, and therefore the accuracy of reading the data in the memory can be effectively improved, and the data processing error can be prevented.

Description

technical field [0001] The invention relates to the field of financial technology, in particular to a magnetic data receiving method and device. Background technique [0002] In the process of financial banknote counting or banknote checking, the DSP (Digital Signal Processing, DSP chip, also known as digital signal processor) of banknote counting or banknote checking equipment is a microprocessor that is especially suitable for digital signal processing operations. The application is to realize various digital signal processing algorithms in real time and quickly) The terminal needs to receive magnetic data, which is acquired by a magnetic sensor. According to the standard protocol, the magnetic data received each time has the same size and fixed format. Each frame The size of the data is 1386 rows and 48 columns, and the data format consists of row numbers plus magnetic data. [0003] In the process of receiving magnetic data, the phenomenon of magnetic data line loss oft...
