This application discloses a data synchronization method and system for vibration protection. A data synchronization method for vibration protection includes: preset reference vibration signals and fixed-point points; collect vibration information in real time through the first acquisition module, based on The vibration information counts the number of synchronization points that are synchronized with the vibration reference signal; when the number of synchronization points is the same as the number of fixed points, the first acquisition module sends a synchronization acquisition instruction to each second acquisition module; the second After the acquisition module receives the synchronous acquisition instruction, it starts sampling in real time until the second acquisition module receives the synchronous acquisition instruction again to complete information acquisition within a single sampling period. The data synchronization method for vibration protection provided by the embodiment of the present application, through the statistics of the actual fixed-point points by the first acquisition module and comparison with the set fixed-point points, can realize that when the main vibration acquisition module cannot generate a synchronization signal, complete the data synchronization method. interception and collection.
Description
technical field [0001] The present application generally relates to the technical field of vibration monitoring, and specifically relates to a data synchronization method and system for vibration protection. Background technique [0002] In the field of mechanical equipment fault diagnosis, the collected real-time signals are usually used to analyze and judge the working conditions of mechanical equipment. For equipment containing vibration devices, it is necessary to collect various physical quantities and electrical signals output by vibration signal sensors in real time, including: rotational speed, acceleration, speed and eddy current. [0003] Traditional synchronous acquisition schemes for sensor data are usually synchronized by means of key phase signals installed on the device sensors. However, the vibration protection system designed by the traditional method is independent of the intelligent early warning system. This independent vibration protection has certain s...
