内嵌1553B终端的部件等效器设计与实现

Design and Implementation of 1553B-bus-terminal-embedded Equivalent Device

为配合导弹武器地面测发控系统检测,设计了内嵌1553B总线终端的部件等效器,增加了总线监视功能,实现了弹地接口以及功能电路的故障诊断功能。给出了部件等效器1553B总线、RS422、以太网以及脉冲功能检测方案。在实现车载测发控系统电气功能检测的前提下,尽可能做到元器件数量少,仪器尺寸小,达到以简单、可靠的方法实现地面测发控电气系统综合检查的目的。

To coordinate the detection of missile test launch and control system（MTLCS）,a 1553B-bus-terminal-embedded equivalent device is designed with the realization of bus monitoring and fault diagnosis of test interface and function circuit.In this study,the detection scheme is presented for equivalent device,1553B bus,RS422,ethernet and pulse function.With the precondition of realizing the vehicle-mounted MTLCS,this scheme can assure comprehensive detection for the electrical system of MTLCS with simple and reliable operations as well as less components and reduced scale equipments.
