摘　　要：针对传统导弹武器环境参数测量系统测点多且分散,以及量程余量大所导致的电缆网笨重等问题,提出了一种基于光纤复用技术的波分复用(Wavelength Division Multiplexing,WMD)与空分复用(Space Division Multiplexing,SDM)相结合的弹体表面场参数组网测量方案;该系统能够有效地实现弹体表面温度、压力、应变等多环境参数同时测量,测量节点可多达320路;分析了大容量光纤传感网络中所面临的关键技术,并阐述了其在导弹上的工程应用分析;为有效满足弹体小型化、轻型化、高灵敏度及减少弹体体积重量提供了新的思路及解决途径。For the problems of the conventional missile environment parameters measurement system,the scattered measuring point,the large range margin and the heavy cable are included,a reuse network measurement scheme of the projectile surface field parameters is proposed,which is based on the optical fiber wavelength division multiplexing and space division multiplexing technology.The temperature,pressure,strain and other environmental parameters can be effectively measured at the same time in the system,and it can be measured up to 320 channels.The key technologies of the large capacity fiber sensor network are analyzed,and the engineering application analysis on the missile is described,which provides a new idea and solution to effectively meet the small,light,high sensitivity and the volume of the projectile.
