Abstract

A maglev train passive speed measuring device comprises the following parts: a passive train beacon arranged on the maglev train; a beacon reading circuit arranged in a long stator power supply interval and mounted on the track, and used for reading a beacon of the passive train and generating a corresponding train beacon signal when the maglev train passes through. According to the device, the key control parameters of a traction system do not need to be transmitted by adopting a wireless communication mode; therefore, not only can physical security isolation be realized, but also potential safety hazards caused by the fact that illegal invasion is easily caused through wireless network access can be prevented; in addition, the device can greatly improve the stability, the real-time performance and the security of data transmission.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a passive speed measuring device for a maglev train and a speed measuring system for a maglev train. Background technique [0002] When the maglev train is running, the body is suspended on the track, and there is no mechanical contact between the train and the track except the power supply rail. Therefore, the traditional speed measurement and positioning method based on mechanical contact is not suitable for the maglev train. [0003] In the prior art, there is a speed measurement and positioning method for maglev trains based on counting sleepers or counting stator cogging. This method calculates the current speed of the maglev train by measuring the time when the maglev train passes through a sleeper or stator cogging with a known distance. Train positioning is achieved by counting the number of sleepers passed or the number of stator cogs. [0004] However, the error o...
