Problems solved by technology
[0005] Therefore, multiple sensors are installed on the CNC machine tool to collect the running state of the CNC machine tool, so that the data collected on the running state of the CNC machine tool forms multi-channel data. The state data of the CNC machine tool collected by multiple sensors usually has heterogeneous characteristics. , there is a potential cross-correlation between the data, and this correlation sometimes changes with time or the state of the CNC machine tool, but there is no research on the cross-correlation of the multi-channel data collected by the multiple sensors to collect the running state of the CNC machine tool. research model

The invention provides a modeling system and method for collected data of sensors on numerically controlled machine tool. The system comprises a plurality of sensors for collecting operating state data of the numerically controlled machine tool serving as multichannel data; an output end of each sensor is connected with an input end of a multichannel sensor interface circuit, and the output end of the multichannel sensor interface circuit is connected with a controller. The controller can be a single chip microcomputer, a PLC, an FPGA processor or an ARM processor. The plurality of sensors can be multichannel temperature sensors, multichannel vibration sensors or multichannel noise sensors; the multichannel temperature sensors are dispersedly mounted on a temperature measuring portion of the numerically controlled machine tool; the number of the plurality of sensors is p, p is a positive integer greater than or equal to 2, and the data collected and transmitted by each sensor to the controller is used as a channel data. The defect that there is no model for studying the cross correlation of the multichannel data of the operating state of the numerically controlled machine tool collected by the plurality of sensors in the prior art is effectively avoided.
Description
