Train energy consumption metering and counting module based on MVB network

Abstract

The present invention discloses a train energy consumption metering and counting module based on an MVB network, including a lowpass filtering sampling circuit, an amplifying circuit, an analog-digital converter, a processor, an MVB communication unit, a data storage unit, and a real-time clock. A current signal outputted by a current sensor in a train is converted into a voltage signal after passing the lowpass filtering sampling circuit, then is transmitted to the analog-digital converter via the amplifying circuit after a filtering, and finally is inputted into the processor after an analog-digital conversion. The processor reads the converted digital signal in real time, and meters, calculates and counts the energy consumption according to an algorithm. The energy consumption data after metering and counting is stored in the data storage unit, and simultaneously, the processor uploads the data in real time through the MVB communication unit and the MVB network. The energy consumption metering and counting module can realize the real-time uploading of the electric energy consumption data of trains by accessing into the MVB network so that a train control center adopts a most energy-saving train control mode.

Description

technical field [0001] The invention relates to a metering and statistics module of train electric energy consumption. Background technique [0002] The level of urbanization in our country is increasing day by day, and the increasingly serious traffic congestion problem is intertwined with energy crisis and environmental pollution. As a green and energy-saving means of transportation, rail transit has become the main means of transportation for citizens to travel. Multifunctional vehicle bus (MVB) is a vehicle bus that connects equipment within a vehicle and between equipment in a fixed train set. The introduction of MVB can significantly increase reliability, with a high degree of integrity to prevent data errors. Due to the complex composition of the urban rail transit system and the large number of equipment, it still needs to consume a lot of energy in the operation process. If the research, planning and management of energy conservation are done well in all aspects of...

Problems solved by technology

Famous companies at home and abroad are also developing corresponding energy metering instruments, but generally such devices only have the function of measuring energy consumption, and the function is single, which brings difficulties to the management of energy consumption and data analysis
