The motor temperature rise is an important indicator for the evaluation of motor performance and the development of motor testing system put forward higher requirements to data acquisition and processing. In view of this, the motor temperature rise test system based on the magnetic power dynamometer which acted as a load was studied. The overall structure and the software algorithm of the system were introduced. The existing synchronous sampling method was put into use in data acquisition system of the motor temperature rise test so that it can automatically test the motor temperature rise. Combining with the instance, proves the accuracy of this method. This method has the superiority of reducing errors and improving accuracy by combining with the instance.

And Performance

At present, the college English testing system has become an indispensable system in many universities. However, the English test system is not highly humanized due to problems such as unreasonable framework structure. This paper combines data mining technology to build a college English test framework. The college English test system software based on data mining mainly realizes the computer program to automatically generate test papers, set the test time to automatically judge the test takers’ test results, and give out results on the spot. The test takers log in to complete the test through the test system software. The examination system software solves the functions of printing test papers, arranging invigilation classrooms, invigilating teachers, invigilating process, collecting test papers, scoring and analyzing test papers in traditional examinations. Finally, this paper analyzes the performance of this paper through experimental research. The research results show that the system constructed in this paper has certain practical effects.
