[Abstract]:In order to improve the practical ability and innovative ability of the graduate students majoring in mechanical and electronic science, a flexible measurement and control platform based on CAN bus is put forward to expand the innovative content of the experiment, taking the typical engineering machinery control system experiment of the specialized practical course as the object. The functional requirements of flexible measurement and control platform are analyzed, and the functional framework of system software is put forward. Taking Lab VIEW as software platform and PEAK USB/CAN as hardware platform, the flexible measurement and control platform of CAN bus is designed by using queue message mechanism, global variable and multi-thread programming mode. And the function verification is carried out on the remote drilling rig control system experiment project. The results show that the designed measurement and control platform can realize automatic message parsing, storage and parameter display, good real-time performance, the function of data drag is convenient for debugging the function of the control system, and the function of dynamic window loading is beneficial to the expansion of the system. The design of the experiment platform is conducive to the design and experiment of the CAN bus control system, and helps to cultivate the students' ability of practice and innovation.
