首先从适航规章出发提出了某大型民机的机翼防冰自动作动功能要求，包括结冰探测、起飞抑制、温度抑制、机组操作指令和发动机引气状态等子功能，以及实现各子功能所需的信号及信号状态组合；接着设计了满足功能要求的基于主导式结冰探测的自动作动组合逻辑电路，推导了逻辑真值表；最后采用matlab软件simulink模块搭建了自动作动组合逻辑电路，数字验证的工作波形与真值表一致，表明设计的自动作动组合逻辑电路能够实现机翼防冰的自动作动功能。

Firstly, according to airworthiness regulation on anti-icing protection activation, the wing anti-icing automatic activation function is provided, including anti-icing detection, inhibition of ta-keoff, inhibition of tem-perature, the functions of crew operation command and engine bleed status. Secondly, the combinational logic cir-cuit of automatic activation based on primary ice detection is designed, and the logic truth table is derived. Third-ly, the simulink model of Matlab is adopted to solve the digital verification of automatic activation function logic. The work wave validated by numerals is compliance with the truth table. The result shows the logic circuit of auto-matic activation is able to meet the wing anti-icing auto activation function.
