分析了单片机控制的氙灯系统中干扰的来源、控制回路中的干扰类型,介绍了此系统在电源、接地、I/O接口等环节上所采取的硬件措施,同时也给出了在软件抗干扰所采用的软件冗余、软件陷阱、软件看门狗等软件抗干扰技术。给出将多种软硬件抗干扰方法综合应用的具体方法。实践证明这些方法是有效的。.
The sources of the interference in the xenon lamp system controlled by the singlechip and the types of interference in the control loop are analyzed. The hardware measures taken by the system in the aspects of power supply, grounding and I / O interface are also introduced. At the same time, Software redundancy, software traps, software watchdog and other software anti-jamming technology. Given a variety of hardware and software anti-jamming method of comprehensive application of specific methods. Practice has proved that these methods are effective. .
