| 摘 要： | 针对飞机电缆故障定位的特点,介绍了一种基于DSP的飞机电缆故障定位设备的设计。利用低压脉冲反射法为被测电缆注入窄带脉冲,采用等效采样对脉冲回波信号进行采集,通过DSP软件对采集数据进行处理,计算电缆故障位置,并将结果通过CAN总线传送到上位机,达到对电缆故障定位的目的。

| Abstract: | This paper presents a design of airplane-cable fault locator,it is based on the characters of airplane-cable faults.The narrow-band pulse is sent to cable it is under test by the method of low-pressure pulse reflection,and then,the pulse echo signal is collected by the method of Equivalent Sampling Theory.By processing the collected data,DSP calculates cable fault location and transmits the results to the host computer via CAN bus,it achieve the purpose of cable fault location. |
