天然气销售系统统一读卡器的设计和实现

Introduction of Unified Card Reader in the Natural Gas Sales Management System

目前在用的各种IC卡表都有厂家自带的售气系统、燃气卡和读卡器,且自带的售气系统基本上都是单机版。营业厅操作人员需要针对不同IC卡表厂家同时使用多个不同售气系统及多个读卡器,且售气流程不同,操作繁琐,为燃气收费带来很大地不便。通过统一读卡器型号、制定IC卡读写卡接口规范、以ActiveX方式封装各厂家提供的动态库、对外提供完全透明的统一接口,实现燃气收费系统的统一,实现不同IC卡表厂家读卡器的统一,为燃气公司的燃气收费统一管理、信息共享和统计分析带来了极大的便利。

In the pilot implementation of the PetroChina Natural Gas Sales Management system, it encountered problems that there are many IC card meter manufacturers and each has its own charging systems, IC cards and card readers, which makes the gas charge operation very complicated. Through implementing measures, such as unified card reader model, etc, it can achieve a unified gas charging system and unified card reader, which can bring convenience to gas charges unified management, information sharing, and statistical analysis as well.
