Embodiment 1
[0038] like figure 1 As shown, the present invention provides a real-time data acquisition and synchronization method for vibration monitoring and excavation equipment, the steps of which are as follows:
[0039] S1, considering that the independent industrial computer used for vibration data storage and the TBM host computer of the tunneling equipment are connected through Ethernet and are in the same local area network, the time and date synchronization between the independent industrial computer and the TBM host computer can be realized through the local area network. renew.
[0040]In the multi-source data collection process of the roadheader, the vibration monitoring data comes from the lower computer, and the roadheading equipment data comes from the upper computer. The existing vibration data and roadheading equipment data are time misaligned due to the complicated working conditions in the data collection process. The local area network time synchronization realizes ...
Embodiment 2
[0059] A real-time data acquisition and synchronization method for vibration monitoring and excavation equipment. In the step S1, the time and date of an independent industrial computer and a TBM host computer are synchronously updated through a developed synchronous time-synchronization control.
[0060] In the thinning process in the step S3.1, indexes such as kurtosis, crest factor, and margin factor of the vibration data are extracted to reflect the characteristics of the time-domain waveform obtained by the monitoring component. The kurtosis, crest factor, and margin factor are sensitive to equipment pulse faults and can be applied to early equipment fault monitoring. At the same time, the kurtosis, peak factor, margin factor and mean square amplitude index are extracted to monitor the key components of the equipment, so as to take into account the sensitivity and stability.
[0061] Other implementation methods are the same as in Embodiment 1.
Embodiment 3
[0063] like figure 2 As shown in the figure, a real-time data acquisition and synchronization system for vibration monitoring and excavation equipment includes a time synchronization unit, a frequency scaling module, a sparse processing module, a data analysis module at the same interval, and a data merging module. and the vibration monitoring lower-level computer is connected, the vibration data collected by the vibration monitoring lower-level computer is connected with the frequency scaling module, the frequency scaling module is connected with the sparse processing module, and the sparse processing module is connected with the data interval analysis module, The data of the same interval analysis module and the tunneling equipment data collected by the tunneling equipment host computer are all connected with the data merging module.
[0064] The time synchronization unit is a local area network time synchronization or synchronous time synchronization control, which synchro...
