Problems solved by technology

[0002] The current motor status detection equipment is mainly single-state independent real-time detection. The more common ones are multimeters, power quality detectors and other equipment. Although these devices are easy to carry, they can only independently detect motor status parameters in time-sharing, and have no response to motor health. The main parameters of the condition include but not limited to vibration, noise, voltage, current, temperature for a synchronous comprehensive diagnostic analysis
Other detection equipment can collect multi-state parameter data in advance, and then perform offline analysis on the working host, but this kind of equipment is generally large, not easy to carry, and the real-time early warning detection is poor
