AUTOMATED MEASURING COMPLEX FOR ACCEPTANCE TESTING OF DC AND UNDULATED-CURRENT TRACTION MOTORS
Journal Title: Наука та прогрес транспорту - Year 2016, Vol 0, Issue 6
Abstract
Purpose. In the paper it is necessary: 1) to familiarize the reader with the modern classification of measurement and diagnostics, familiarize with problems of automating the measurement of basic parameters during program execution of qualification tests of traction motors; 2) to make recommendations to improve the measurement ac-curacy, reduce labor intensity of work for carrying out measurements, and reduce the requirements for the qualification of the staff; 3) to provide practical implementation of measurement system, built on the basis of the practical recommendations contained in the article. Methodology. The work presents the classification of measurement and diagnostic tools. The author considered a list of equipment that can be used in measurement systems, as well as third-party options for measuring complex and measuring complex using stand management system. Their functional schemes were proposed. The author compared the advantages and disadvantages of these schemes to make recommendations on areas of their optimal use. Findings. Having analyzed the functional scheme of measuring systems, it was found that the use of the control system microcontroller as a measuring complex is expedient if the measurements have largely a test process control function. The use of a third-party measuring complex is more appropriate in cases when it is required: to eliminate dependence on the stand management system, to provide high mobility and reduce the requirements for the qualification of the staff. Originality. The work presents a brief over-view of the measurement means. The author developed the functional schemes of measuring systems using stand management system and third-party measuring complex, proposed the criteria for evaluating their optimal use. Practical value. Based on the proposed functional diagram, the measuring system on National Instruments hard-ware and software basis was set up. The sensors by LEM Company were used as primary transducers for the measurement of currents and voltages. Thanks to chassis compact size, it was united in one body with the power supply for sensors. Thus, it was possible to reduce the size of the entire complex, simplify and speed up its preparations for the measurements.
