摘　　要：针对某型武器系统配电车变频机组某些故障早期无法准确及时发现、长期运行时容易导致兵器产生突发性故障的状况,为提高供电质量和变频机组工作的可靠性,设计了基于DSP的小波分析故障检测系统,通过DSP高速采集变频机组的输入或输出电流,再经串口送入计算机,由特定的小波分析软件准确诊断是否有故障产生,从而提高武器系统工作的可靠性和供电质量。It is difficult to have an accurate and quick diagnostic of the fault on frequency converter of a weapon system. With the aim of reducing the faults rate and enhancing the reliability of the frequency convener system, the diagnostic system on fault on frequency converter of the weapon system based on the theory of wavelet of DSP is made. The fault diagnostic system will be of great military importance to make sure of reliable working： of the weapon system.
