摘　　要：据航标遥测遥控终端的高可靠性要求,对影响航标遥测遥控终端可靠性的主要因素做了分析,并针对硬件可靠性设计和软件可靠性设计的要求,提出了采用双机热备份、终端远程在线升级的可靠性设计方法.采用Lambda Predict、Relex Studio可靠性预计软件,对终端硬件系统的可靠性进行评价,结果显示航标遥测遥控终端理论可靠度指标和有效度指标均满足电子设备和信息系统建设的可靠性要求.实际应用表明,该技术不仅能够显著提高终端的可靠性,还可提高系统升级与维护的便利性.According to the high reliable request for remote monitoring system of navigational marks, we analyze major influence factors of the reliability index for remote monitoring system of navigational marks, according to the hardware reliability design and software reliability design, we propose methods for the reliability design base on system redundancy backup, remote online upgrade of terminal, and we use the Lambda Predict and Relex Studio predict softwares to evaluate the reliability of terminal hardware system. The results show that remote monitoring system of navigational marks theory reliability and validity indicators meet the require- ments of electronic equipment and information system reliability. The practical application proved that the tech- nologies not only can enhance the terminal＇s reliability obviously, but also can enhance the convenience of system upgrade and maintenance.
