计算机控制系统是综合航电系统的核心,它的稳定性和可靠性是至关重要的,而系统的抗干扰性能是系统可靠性的一个重要指标,随着计算机控制系统在机载电子装备中应用更加广泛,抗干扰措施研究是计算机控制系统应用中一个不可忽视的重要内容。干扰信号影响计算机控制系统正常工作的方式主要是通过硬件电路和软件电路对系统进行干扰。文章分析了干扰信号窜入计算机控制系统硬件电路的通道,并提出了抗干扰的措施。 Computer control system is the core of integrated avionics system, its stability and reliability are crucial, and system anti-interference performance is an important indicator of system reliability. With the computer control system in the airborne electronic equipment Application is more extensive, anti-jamming measures research is a computer control system applications can not be ignored important content. Interference signals affect the normal operation of computer control system is mainly through hardware and software circuits to interfere with the system. The article analyzes the channeling of interference signal into the computer control system hardware circuit and puts forward the anti-interference measures.
