五十年代。军用飞机飞行任务的要求已达到了相当复杂的程度。用独立的。自给自足式的电子《航空电子》子系统已不再能够满足这种需要。人们已经认识到需要把这些子系统综合起来以便共享信息和资源。六十年代中期。航空电子系统的综合在子系统接口复杂性和互连电缆线的体积和重量方面产生了戏剧性的增加。当时的布线也相当复杂。以致于进行更改和对系统进行测试都很困难。而且费用很高。数字技术——在串行数据总线上进行时分多路传输——是解决此问题的显而易见的方法。(见图1)
Fifties The requirements for military aircraft missions have reached a fairly complex level. With independent. Self-contained electronic “avionics” subsystems are no longer able to meet this need. People have come to realize that these subsystems need to be integrated in order to share information and resources. The mid-sixties. The integration of avionics systems has dramatically increased the subsystem interface complexity and the size and weight of interconnecting cables. At that time the wiring is quite complicated. So it is difficult to make changes and test the system. And the cost is high. Digital technology - time-division multiplexing on the serial data bus - is an obvious way to solve this problem.
