摘　　要：装备电缆性能测试和故障检测的方案,基于电桥检测法,以AT89C52单片机为核心,利用X9241代替手动调节的电位器,使用电压比较电路代替常用的电压表实现电桥平衡的自动调节,从而实现测试的全自动化。实验表明通过该方案样机能准确地对电缆故障进行检测。A method which can be used for equipment cable capability test and faults measurement based on the electric bridge measurement. The AT89C52 is taken as the core, and use X9241 instead of the manual implement. For realizing the self-regulation of the electric bridge, the prototype machine uses the voltage relatively circuit replacing electric meter in common use. So it can realize the automatic measurement. Testing results show that the prototype machine can measure the cable faults in high precision.
