Intelligent cloud vibration monitoring system and method based on Bluetooth and nbiot dual wireless technology

Abstract

The invention relates to an intelligent cloud vibration monitoring system and method based on Bluetooth and NBIOT dual wireless technologies. When the system is in NBIOT mode, the short-waveform vibration data is collected and uploaded to the server. After the short-waveform vibration data is collected, the short-waveform vibration data is intelligently analyzed and the equipment fault is judged. If the equipment is found to vibrate abnormally, the alarm status will be uploaded immediately. and trigger the collection of long-waveform vibration data, and store the collected long-waveform vibration data in the external expansion storage unit; when the system is in the Bluetooth mode, temporarily collect the vibration data, and simultaneously store the currently collected vibration data and the external expansion storage unit. The long-waveform vibration data stored in the storage unit is uploaded to the server at the same time. After the current vibration data collection is completed, the current vibration data is intelligently analyzed and the equipment failure is judged. The invention selects Bluetooth 5.0 and NBIOT dual wireless technology to combine, and meets the needs of wide frequency response and long data transmission.

Description

technical field [0001] The invention relates to the technical field of vibration monitoring, in particular to an intelligent cloud vibration monitoring system and method based on Bluetooth and NBIOT dual wireless technologies. Background technique [0002] At present, NBIOT technology is more and more recognized in the industrial field. In the field of vibration monitoring, several domestic companies have begun to try, but their vibration sensing units have a frequency response within 1Khz. As we all know, rotating machinery Equipment, whose fault frequency is above 1Khz accounts for the majority, and the acceleration sensor with 10Khz frequency response range can cover more than 95% of the faults of rotating mechanical equipment, so the NBIOT intelligent cloud vibration monitoring system using the 1Khz frequency response range acceleration sensor is only Instead of the traditional vibration transmitter function, it is difficult to realize the function of precise analysis an...

[0002] At present, NBIOT's technology is more and more recognized in the industrial field. In the field of vibration monitoring, several domestic companies have begun to try, but their vibration sensing units have a frequency response within 1Khz. As we all know, rotating machinery For most equipment, the fault frequency is above 1Khz, and the acceleration sensor with a frequency response range of 10Khz can cover more than 95% of the faults of rotating mechanical equipment. Therefore, the NBIOT intelligent cloud vibration monitoring system using the acceleration sensor with a frequency response range of 1Khz is only Instead of the traditional vibration transmitter function, it is difficult to realize the precise analysis and diagnosis of equipment faults

While the smart cloud monitor uses a 10KHz acceleration sensor, it should choose a sampling rate up to 50K to meet such a frequency range. This is a huge challenge for NBIOT data transmission, because NBIOT data transmission has the defects of low rate and high delay, which leads to its Cannot transmit large amount or long waveform data
