介绍了某型航空发动机温度控制输出信号测量的两种方法,针对输出信号的特点对两种方法进行了比较。设计了基于测周法的频率和占空比电路。通过实验,验证了该方法的可行性。 Two methods for measuring the temperature control output signal of a certain type of aeroengine are introduced. The two methods are compared according to the characteristics of the output signal. A frequency and duty cycle circuit based on the test cycle method is designed. Through experiments, the feasibility of this method is verified.
