提高IC卡装置写卡数据可靠性方法研究

Approach to Increasing Reliability of IC Card Data

分别从IC卡应用系统的硬件和软件两个方面研究了如何提高IC卡装置写卡数据的可靠性的方法。造成写卡数据出错的原因较多,根据统计分析,最为常见的原因主要是电源波动或偏低、附近大电流回路的通断(如电磁阀和继电器等),以及人为的(多为有意的)快速插拔,针对这3种最常见的情况,给出了实用的解决方案。

Rellability of writing IC card data from hardware and software of a unit is discussed in this paper. According to statistic and analysis,the reason of the error data written to IC card is relative to much things,the most familiar reason is the power supply undulate or low and nearby, big electric current back track of break （such as the electromagnetism valve and after electric appliances etc. ）, and artificial put to pull out quickly, aiming at the most familiar circumstances, the practical solving methods are given in the paper.
