Embodiment 1

[0019] A method for real-time monitoring of the motor current of a shot blasting machine head in this embodiment, the steps of which are as follows:

[0020] Step 1: Change the parameter OUT group 07 address content value of the shot blasting machine head motor LS inverter to 1, and set the second analog output terminal (current 0-20mA) of the inverter (A02CM) to the actual current output , to map the actual operating current to the output terminals of the inverter;

[0021] Step 2: Connect the second analog output terminal (A02CM) to the analog module integrated in the Siemens S7-300PLC control system through wiring, and perform calibration in the program;

[0022] Step 3: Develop the WICC monitoring screen on the host computer, refer to the historical trend control, and complete the real-time monitoring system of the motor current of the shot blasting machine through the configuration. The trend curve of the motor current of the shot blasting machine is configured with a tex...

Abstract

The invention discloses a real-time shot blasting machine ramming head motor current monitoring method and belongs to the process monitoring technology field. The method comprises steps that 1, an actual operation current of a shot blasting machine ramming head motor frequency converter is mapped to an output terminal of the frequency converter; 2, the actual operation current of the frequency converter is acquired by a PLC control system to an analog quantity module, and calibration is carried out in a program; 3, a WICC monitoring frame is developed in a host computer, a historical trend control is utilized, and a real-time shot blasting machine ramming head motor current monitoring system is accomplished through configuration; and 4, according to time requirements of configuration WICC variable filing, a SQL database is established. The method is advantaged in that real-time monitoring is realized, the database function is realized, the wheel motor current data in production operation can be kept, wheel shot blasting effect quality can be traced, moreover, an alarm function is developed, and top and bottom limit function protection on the shot blasting effect is realized.

Description

technical field [0001] The invention relates to the technical field of process monitoring, and more specifically, to a method for real-time monitoring of the motor current of a shot blasting machine. Background technique [0002] With the rapid development of my country's railway industry, the speed of trains is getting faster and faster. As an important part of the train running part, the train wheel, its service life will directly affect the safety of train operation, and the reliability of the wheel product directly affects the overall quality of the wheel. Performance, before the wheel products leave the factory, the surface shot blasting is carried out according to the requirements of the process to ensure that the strength of the wheels meets the requirements of product specifications. At present, there is no real-time monitoring system for the motor current of the wheel shot blasting machine used on site, and the monitoring process is uncontrollable, which greatly affe...
