The data structure course is very important for information communication technology learning. However, some students can learn data structures well, but most students feel difficult to understand the contents of the data structure course. Therefore, a data structure exercise system applying self-regulated learning mechanism was used for students to learn by their own goals and strategies, and this...
According to requirements, a solution of remote PLC experiment system has been introduced, including total architecture, hardware and software design. We made a remote experiment in order to control simple mechanical equipment with S7–200 PLC. Then through CP243-1IT, mechanism, PLC, server and clients from internet are mutually connected. By visiting lab web and operating panel of console interface,...
A new method to fault diagnosis of bearing based on order tracking technique and autoregressive (AR) spectrum is presented. Firstly, the transient vibration signals during run-up condition of gearbox are re-sampled using order tracking technique. Therefore, the time domain transient signals are transformed into angle domain stationary signals. Then the AR model estimation is applied to angle domain...
