工业诊断是一门年青的跨学科的新技术领域,尽管人们在几百年前开始使用机器的时候就已经不可避免地开展了故障的诊断,但那是初级的,原始的,只能用感官直接判断。诊断技术成为一门学科则是近十几年的事情。这一方面是由于近代机械设备、电子系统、结构工程都日趋复杂和精密,对它们运行的精度及可靠性要求愈来愈高。另一方面也因为近代仪器仪表,计算机技术的发展,使得现代化的诊断成为可能。 Industrial diagnosis is a young and interdisciplinary area of ​​new technology, and although people have inevitably carried out fault diagnosis when they started using the machine hundreds of years ago, it is a primary, original, sensory Judge directly. Diagnostic technology to become a subject is the last ten years. This is partly due to the increasingly complicated and sophisticated modern mechanical equipment, electronic systems and structural engineering, and the increasingly higher requirements for the accuracy and reliability of their operation. On the other hand, modern instrumentation and computer technology have also made it possible to modernize diagnostics.
