Embodiment Construction

[0016] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0017] Such as figure 1 As shown, the hardware structure of the measurement and control system of the present invention includes hardware such as a bearing life tester, a sensor, a temperature controller, a frequency converter, and a communication board, and also includes a human-computer interaction interface, and each hardware part is realized by a measurement and control software system based on LabVIEW. Testing of bearing life. The LabVIEW-based bearing life test measurement and control software system of the present invention includes a top-level message queue and a bottom-level message queue. As the core control unit of the entire measurement and control software, the top-level message queue is not only used for the event response generated by the corresponding software interface, but also used for triggering Other underlying message queues...

Abstract

The invention provides a bearing life test and control software system based on LabVIEW. The system includes a top message queue and an underlying message queue, wherein the underlying message queue includes at least two message queues of a spindle speed control message queue, a load control message queue, a lubricant heating control message queue, a PLC input and output control message queue, a test signal acquisition and alarm message queue, a test load spectrum running and timing control message queue and a test data record message queue, and each underlying message queue receives a messageinstruction delivered by the top message queue, executes the corresponding message queue and feeds the execution result to the top message queue. The system is advantaged in that the system greatly improves operation stability, reliability and maintainability of a bearing life test and control system, and further improves flexibility and expandability of system control, and more importantly, thetest result of the bearing life test is made to be more accurate, and the system is convenient to fully grasp the bearing life test.

Description

technical field [0001] The invention belongs to the design field of LabVIEW measurement and control software, in particular to a bearing life test measurement and control software system based on LabVIEW. Background technique [0002] The bearing life test is to analyze the fatigue life and reliability of the bearing by simulating the environment in which the bearing is used and the actual operating conditions. Conventional bearing life tests include speed control of test bearings, load control, and heating control of lubricating oil. Temperature sensors, force sensors, pressure sensors, vibration sensors, speed sensors, etc. , speed, etc. are measured, and the closed-loop control of the test and the diagnosis of bearing faults are carried out according to the measured values. [0003] The development of bearing life test measurement and control software design is from C language design, to object-oriented programming C++, and then to LabVIEW programming language. LabVIEW ...
