一种机载航空服务器的离散控制输入输出信号的设计方法

Design of Discrete Input and Output Control Signal about the Aviation Server

本文针对航空服务器对离散输入输出信号需要严格的时序控制的特点,提出一种离散输入输出信号的设计方法。该方法通过对I2C总线、控制芯片、IO芯片、触发器、电压隔离等器件的控制来实现离散输入输出信号的设计,满足航空服务器场合的应用。

This paper presents a method for designing discrete input and output control signal about the aviation server because of strict control characteristics. According to control the I2C bus, control ICs, IO chips, flip-flop and voltage isolation devices to achieve this design. This approach is consistent with the aviation server area.
