摘要
根据多SIM卡初始信息写入要求,研究了基于网络的计算机控制系统,计算机通过集线器构成的网络控制带有网络接口的ARM控制板,ARM控制板上的串口连接读卡器完成多SIM卡初始信息的写入。根据读卡器和SIM卡有关技术规范,设计了PC与嵌入式板之间的网络通信协议,编写了Linux操作系统下的读卡器接口函数(驱动)。控制系统可用作电信行业SIM卡相关设备上的计算机控制系统。
To meet the requirements of SIM card initial information programming, the computer control system based on network is developed. A PC controls several ARM boards through network interface and each ARM board controls several readers to complete the SIM card programming through RS-232 interface. According to relevant technical specifications of smart card reader and SIM card, the protocol used by PC and ARM boards in network communication is carried out, and the smart card reader driver on Linux OS is developed. The system meets the demands of telecommunications industry in SIM card programming.
