铁路GSM-R SIM卡读写次数测试方法研究

Study on Read and Write Times Test Method of Railway GSM-R SIM Card

简述铁路GSM-R SIM卡的日常维护检修状态,尤其是ATP列控类SIM卡的运用情况,指出SIM卡日常维修缺少相应测试手段的问题。为了掌握GSM-R SIM卡在日常应用场景中的真实使用状态,提出了SIM卡读写次数的检测方法,并在实验室和现场进行了测试和验证,形成了一套可行有效的SIM卡数据采集方法,为后续开展铁路GSM-R SIM卡应用模型的建立及使用寿命的研究奠定基础。

The maintenance conditions of GSM-R SIM card,especially the SIM cards for ATP and train control,are described.The problem of lacking proper test means in the maintenance of SIM cards is pointed out.In order to learn real use scenarios of GSM-R SIM card in actual application,we put forward a test method of detect the read and write times of SIM cards.It has been tested and verified both in laboratory and field.A set of feasible and effective data acquisition method of SIM card is established,laying a basis for further establishment of application model of GSM-R SIM card and research on service life.
