背景技术Background technique
现有的机电设备在运行中出现故障时，通常采用熔断器或空气开关进行保护。由于故障信号不会预先获知，使得此时会造成机电设备非正常停机，尤其是某些特殊设备，如电梯等，其非正常停机会带来很大的不安全因数或重大经济损失，故对其进行提前获取故障信号的研究具有重要意义。然而，在研发人员采用现有的设备和方法对机电设备进行分析时，往往无法准确判断机电设备的运行是否正常，因而对机电设备的运行分析中仍存在难题。Existing electromechanical devices are usually protected by fuses or air switches when they fail during operation. Since the fault signal is not known in advance, the electromechanical equipment will be abnormally shut down at this time, especially for some special equipment, such as elevators. The abnormal shutdown will bring great unsafe factors or major economic losses, so It is of great significance to carry out research on obtaining fault signals in advance. However, when the R&D personnel use the existing equipment and methods to analyze the electromechanical equipment, it is often impossible to accurately judge whether the operation of the electromechanical equipment is normal.
