针对基于1553B总线的导弹武器系统通信协议设计及其可行性验证困难的问题,设计了弹上系统1553B总线通信协议并进行了仿真验证。采用仿真总线系统通信、计算及测量总线负载率的方法对通信协议可行性进行了验证。总线负载率设计计算和仿真试验验证表明:该弹上通信系统的实际总线半载负载率为14.76%、满载负载率为26.72%,远小于1553B总线最大负载不超过50%~70%的要求,理论设计可行,可以满足弹上数据流通信要求。

In view of design of 1553B bus communication protocol of missile weapon system and its difficult feasibility verification, the missile-born system's 1553B bus communication protocol was designed and simulated. Through simulating the bus communication system, calculating and measuring the bus load rate, the communication protocol's feasibility was validated. Bus load rate design-calculation and simulation verification show that: the actual half bus load rate of the missile communication system is 14.76% and full load rate is 26.72%, far lower than the requirement that the maximum 1553B bus rate load is not more than 50% to 70%; theoretical design is feasible to meet the communication requirement of missile data flow.
