摘　　要：LRM模块是第四代综合式航电系统的硬件基础,具有标准化程度高,便于维护的特点,可以将三级维护简化为二级维护,缩短研制周期,减少全寿命成本。目前包括美国在内的各国都已经或正在发展基于LRM模块的航电系统。文中介绍并比较了目前各主流LRM模块标准,认为VITA48模块在技术开放性、技术难度、兼容性等指标上都有着良好的表现,较适合我国实际情况。建议以其为基础,建立我国自己的LRM模块设计标准和规范。Line Replaceable Module （LRM） is the hardware base for the 4th integrated avionics system. It defined the kind of module, which with uniform standard and was easy for maintenance. Therefore it can simplify the tradition 3-level maintenance into 2-level maintenance, shorten development period and cut full-life cost. Now many countries included USA are developing their own integrated avionics system based on LRM. It was introduced detailed and compared in detail several leading LRM standards in the world. For the good performance on technique open, development difficulty and compatibility, VITA 48 was thought to be suitable for china. It was suggested strongly that our own LRM standard and specification should be developed as soon as possible, based on VITA 48.
