资料介绍

飞控计算机采集飞机上各类传感器和其他飞行控制系统的输入信息,分析解算后控制飞行姿态。频率信号的采集就是其中重要的数据信息类型之一。在此采用可编程芯片FPGA实现将频率信号转换为数字信号的方法。这种设计思想避免了搭建复杂的硬件电路来实现该功能,降低了模块硬件设计成本,节省了印制板布局空间,降低了设计复杂度,同时设计该功能的测试接口,以便于该功能故障后能够准确定位故障源。

Flight control computer collects the input information from every kind of sensor and other flight control systems, which is analyzed and calculated to control flying attitude. Frequency signal is one of important signals in collected information. The programmable chip FPGA is adopted to realize the frequency signal conversion to digital signal. This design method avoided the building of a complicated hardware circuit for the realization of this function,reduced the hardware module design cost and saved PCB layout space,lowered the design complexity. The test interface of this function was designed to confirm the failure source when the function fault occurred.
