A Novel Self-Powered Passive Response System with Real-time Updating Information

Abstract

The invention discloses a new type of self-powered passive answering system whose information can be updated in real time, which belongs to the field of rail transit technology, and solves the problem that the internal information of the passive answerer in the prior art cannot be updated in real time because there is no internal power supply device, thereby As a result, it is impossible to carry out real-time data transmission with the train control system when the train operating conditions and line conditions change, which includes the fan chassis arranged on the passive transponder side, and the passive transponder and the fan chassis are fixed on the On the rail, the fan chassis is provided with an air guide port along the axial side of the rail. One side of the air guide port is provided with a wind turbine, and the wind turbine is arranged in the fan chassis. machine, the generator is connected to the passive transponder through a filter and rectifier circuit.

Description

technical field [0001] The invention belongs to the technical field of rail transit, in particular to a new type of self-powered passive system whose information can be updated in real time. [0002] answering system. Background technique [0003] With the continuous development of my country's national economy and the continuous improvement of people's living standards, traveling by EMU trains has become the main mode of national railway travel in my country. In 2019, EMU trains sent a total of 460 million passengers, a year-on-year increase of 16.9%. An average of 7.42 million passengers are dispatched per day, accounting for 62.5% of the national railway passenger dispatch volume. The increasing demand for EMU train services has accelerated the density and speed of train operation, and at the same time, it has also increased the pressure on the long-term safe and stable operation of high-speed EMU trains. [0004] The balise is a small yellow box installed between the tw...

Problems solved by technology

[0005] Aiming at the problem that the passive transponder in the prior art has no internal power supply device, its internal information cannot be updated in real time, resulting in the inability to perform real-time data transmission with the train control system when the train operation and line conditions change, the present invention Provide a new self-powered passive answering system passive balise whose information can be updated in real time. The purpose is to enable the passive balise to obtain energy and form a network with the active balise, which will be more accurate for train positioning and information transmission. very important role
