Data monitoring system for inverter of passenger train

Abstract

The invention provides a data monitoring system for an inverter of a passenger train. Operation parameters of the inverter are collected and processed through a controller, and the processed operation parameters are sent to an upper computer for processing and displaying; the controller and the upper computer integrate measurement and display functions of data measurement instruments with multiple different functions in the prior art, and overcome the disadvantages, which the data measurement instruments have, of being heavy in appearance, expensive in price, vulnerable to interference, low in scalability and the like, and the problem that multiple data measurement instruments cannot meet on-site measurement requirements in Tibetan Plateau and other special natural environments and climatic conditions is solved by the controller and the upper computer; besides, when parameter setting information is input from the outside, the upper computer sends the parameter setting information to the controller, the controller updates corresponding parameters of the inverter online, and therefore the problems that the data measuring instruments in the prior art only have the measurement function, and cannot set and update relevant parameters of the inverter to the controller in the measurement process is solved; therefore, the improvement of the development efficiency is facilitated.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a data monitoring system for a railway passenger car inverter power supply. Background technique [0002] The inverter power used inside the railway passenger car is usually hung under each car in the form of a box, and is used to supply power for three-phase loads such as air conditioners and oxygen generators on the car. In the process of development, verification and use of inverter power supply electrical equipment, data measuring instruments with different functions are usually required to monitor the real-time data and waveforms of current, voltage, temperature and other signals during the operation of the inverter power supply; and waveform analysis to judge the working status and performance of the electrical equipment of the inverter power supply. [0003] Currently commonly used data measuring instruments include oscilloscopes, temperature guns, current clamp...
