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 ...

[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.

Abstract

The invention provides a vibration monitoring and tunneling equipment data real-time acquisition synchronization method and system, which are used for solving the technical problem that synchronous analysis of vibration monitoring and tunneling equipment data is difficult due to different storage positions, large sampling frequency difference and difficult time synchronization of the vibration monitoring and tunneling equipment data. The method comprises the following steps: synchronously updating the time and date of equipment for acquiring vibration data and tunneling equipment data; selecting the smaller one of the sampling frequencies of the vibration data and the tunneling equipment data as a reference frequency, and scaling the sampling frequency of the vibration data or the tunneling equipment data by using the reference frequency; sparse processing is carried out on the collected vibration data, so that the sampling time interval between two adjacent points in the vibration data is consistent with the tunneling equipment data; and combining the rarefied vibration data with the tunneling equipment data to complete synchronous linkage analysis of the vibration data and the tunneling equipment data. The synchronization efficiency and automation degree of the vibration data and the tunneling equipment data are high, and the method is easy to implement.

Description

technical field [0001] The invention relates to the technical field of data synchronization, in particular to a vibration monitoring and real-time data collection and synchronization method and system for excavation equipment. Background technique [0002] The vibration monitoring system, as an additional sensor for monitoring the driving state of the equipment, can be divided into two methods: offline measurement and online measurement. Compared with the offline vibration measurement system which needs to stop the measurement, the vibration online measurement system can realize the real-time acquisition of vibration data during the equipment excavation process. On the one hand, the data acquisition of the vibration online monitoring system is usually high-frequency acquisition, and the sampling frequency is much greater than 1Hz. Therefore, an independent industrial computer with high performance and large storage capacity is required for the acquisition, storage and proces...
