【摘要】 为满足DAS前端与SPM模块数据传输的需求,设计和实现了DAS-SPM通信接口模块。给出了一种FC总线与CAN总线间数据转换及相互通信方法,解决以CAN总线与FC总线数据相互传输的问题。软件同时支持故障记录管理功能和通用活动处理功能。经过对软件的自测试、故障态测试、支持DSP获取后端设备版本信息的测试,验证了其功能。更多还原

【Abstract】 In order to meet the requirement of communication between DAS(Distributed Aperture System)module andSPM(Signal Processing Module),the DAS-SPM communication interface module was designed and implemented.A methodof frame transition between FC(Fiber Channel)bus and CAN(Controller Area Network)bus was given,which solve the prob-lem of communication between CAN bus and FC bus,at the same time,the software supports recording fault and handlinggeneral activity.According to serial tests,such as the state of fault,supporting DSP(Digital Signal Processing)accessing tothe backend equipment version information,the practicable of the software was provev.更多还原
