Abstract
The invention discloses a method for debugging and correcting data errors of a Mifare1 IC (Integrated Circuit) card consumption machine. An entire data judgment process is divided into a debugging process and an error correcting process, wherein each data block of the Mifare1 IC card is provided with 16 bytes; the first 15 bytes are designed for storing service data; and a sixteenth byte is used for storing a lowest byte of the accumulated value of the first 15 bytes. Through special setting of the two data judging processes, i.e., the debugging process and the error correcting process, the data correcting accuracy of the IC card consumption machine can be increased greatly, and the method is low in cost, has high market competitiveness and is worth of popularizing and applying.
Description
Technical field
Debugging and correction processing method while the invention discloses a kind of Mifare 1 IC-card charge machine error in data.
Background technology
Along with science and technology ground is constantly progressive, increasing place uses machine for punching the card, charge machine etc., has facilitated people's life, has improved the quality of life; The IC-card charge machine is as wherein the most frequently used a kind of, in the situation that data make a mistake, has brought much inconvenience to people and businessman; The more existing charge machine of the IC-card with error correction, precision is not high, job insecurity, urgently improves.
Summary of the invention
The problem existed in order to solve correlation technique, the embodiment of the present invention provides a kind of data error-correcting method that integrates the IC-card charge machine of mistake and error correction.
Technical scheme of the present invention is as follows:
A kind of data error-correcting method of IC-card charge machine, is characterized in that, whole data judgement is divided into debugging and two processes of error correction; Wherein Mifare 1 every of IC-card data are provided with 16 bytes, are designed to the data of front 15 bytes for storing usage data, a minimum byte of the 16th front 15 the byte accumulated values of bytes store.
Further, described debugging process is as follows:
Read IC-card monoblock data, by front 15 byte accumulation calculating, make comparisons by result of calculation low byte and the 16th byte, identical words representative data is correct, and difference is exactly error in data.
Further, described error correction procedure is as follows:
One group of data of first of IC-card storage, backup with second, stores identical data.After reading two blocks of data, do respectively the process of debugging, if a blocks of data mistake wherein covers wrong data block with an other blocks of data.
The present invention is by debugging and two data deterministic processes of error correction, and wherein Mifare 1 every of IC-card data are provided with 16 bytes, be designed to the data of front 15 bytes for storing usage data, a minimum byte of the 16th front 15 the byte accumulated values of bytes store; Correcting data error precision, the cost that can increase substantially the IC-card charge machine be low, have the market competitiveness, is worthy of promotion and application.
The accompanying drawing explanation
Fig. 1 is theory diagram of the present invention;
Fig. 2 is 16 byte schematic diagrams of the present invention.
embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, a kind of data error-correcting method of IC-card charge machine, is characterized in that, whole data judgement is divided into debugging and two processes of error correction; Wherein Mifare 1 every of IC-card data are provided with 16 bytes, are designed to the data of front 15 bytes for storing usage data, a minimum byte of the 16th front 15 the byte accumulated values of bytes store.
Further, described debugging process is as follows:
Read IC-card monoblock data, by front 15 byte accumulation calculating, make comparisons by result of calculation low byte and the 16th byte, identical words representative data is correct, and difference is exactly error in data.
Further, described error correction procedure is as follows:
One group of data of first of IC-card storage, backup with second, stores identical data.After reading two blocks of data, do respectively the process of debugging, if a blocks of data mistake wherein covers wrong data block with an other blocks of data.
The present invention is by debugging and two data deterministic processes of error correction, and wherein Mifare 1 every of IC-card data are provided with 16 bytes, be designed to the data of front 15 bytes for storing usage data, a minimum byte of the 16th front 15 the byte accumulated values of bytes store; Correcting data error precision, the cost that can increase substantially the IC-card charge machine be low, have the market competitiveness, is worthy of promotion and application.
Although below by reference to the accompanying drawings the preferred embodiments of the present invention are described; but the invention is not restricted to above-mentioned embodiment; above-mentioned embodiment is only schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present invention; under the prerequisite without prejudice to aim of the present invention and claim; can make like multiple types and meaning, within such conversion all falls into protection scope of the present invention.
