Numerically controlled machine tool electrical parameter collection system and method

Abstract

The invention belongs to the technical field of the numerically controlled machine tool, and discloses a numerically controlled machine tool electrical parameter collection system and method. A hardware platform is constructed by Siemens PLC200, Siemens PLC300 and WB9128 power collectors, three WB 9128 power collectors are used for respectively collecting a turn-broaching numerically controlled machine tool electrical parameter, a drilling machine electrical parameter and a numerically controlled lathe electrical parameter, and then an electrical parameter analog signal is transmitted to analog input modules of S1-300 and S7-200 through a WB9128 sensor analog quantity output OUT, and then the PLC program is compiled to collect and process the analog quantity data; the WINCC configuration software is utilized to communicate with the PLC through a PROFIBUS-DP bus, and the electrical parameters are saved, and the process filing is performed; and the intelligent control of the numericallycontrolled lathe is realized.

Problems solved by technology

[0007] (1) In the prior art, the collector is not used to separately collect the electrical parameters of the CNC lathe, the electrical parameters of the drilling machine and the electrical parameters of the CNC lathe, and then write the PLC program to collect and process the analog data, resulting in poor control effect of the CNC machine tool

[0008] (2) Some of the existing methods use the RS485 communication method to transmit digital electrical parameters. Due to the low acquisition frequency, there is a problem that the peaks and valleys of the electrical parameters cannot be accurately obtained during the frequent starting and braking stages of the motor, and the error is relatively large.

[0009] (3) Many of the existing technologies use electric energy meters to collect energy consumption data, and cannot obtain instantaneous values ​​of other electrical parameters, and cannot obtain real-time curves to grasp the life of machine tool blades
