Problems solved by technology

[0002] At present, the application in the field of equipment status detection and fault diagnosis mainly adopts wired networking. There are many problems in this solution: such as difficult wiring, large amount of rerouting, immovable, easy to damage cables, long and easy connection time Poor contact, etc.
However, when multiple wireless vibration sensors work at the same time, the simultaneous transmission of data by multiple sensors will cause wireless signals to interfere with each other, and the data cannot be demodulated correctly, resulting in a high communication failure rate and low accuracy and timeliness of effective data transmission.
