Embodiment Construction

[0031] The three-dimensional magnetic encoding method and its application technology in the field of positioning and speed measurement of maglev trains are a key technology related to the excitation of stator windings, traction force matching, and energy-saving operation of maglev trains. With the rapid development of the rail transit system in the direction of green, safe and intelligent, higher requirements are put forward for the train positioning technology, such as information collection speed and information accuracy. The present invention monitors state information such as the position, speed, and acceleration of the maglev train by adopting a three-dimensional magnetic encoding marking method based on the information calibration method, and provides basic basis for precise control of the maglev train.

[0032] The three-dimensional magnetic code marking method of the present invention adopts the 'N', 'S' polarity of the permanent magnet and the non-magnetic '0' vacancy ...

Abstract

The invention discloses a three-dimensional magnetic code based train positioning identifying method. The method comprises the following steps: combining the magnetic N pole, S pole and 0 vacancy of apermanent magnet, which represent numerical values 2, 1 and 0 respectively, to form three-dimensional magnetic codes of train positioning information; pasting the three-dimensional magnetic codes along a track according to certain interval; and performing information reading and decoding by an electromagnetic induction type identifying and reading device mounted on the train, so as to obtain coordinate positioning as well as the speed and acceleration of the train. In the method, the preset positions of the train are subjected to coded combination by using three code elements according to a matrix sequence way, and the preset sequences of different code elements represent different positional information; and the method relates to the technologies such as coding principle, inductive identification and fast decoding identification. The most remarkable characteristics of the patent are strong environmental suitability and high reliability, and the method can be used normally in varioussevere environments such as heavy dust, poor light, low temperature and rainy and snowy weather.

Description

technical field [0001] The present invention relates to technologies such as electromagnetic induction and combined coding, and more specifically relates to a three-dimensional magnetic coding method and its application in the fields of train positioning marks and speed measurement. Background technique [0002] At present, the maglev train is a new type of transportation developed by the country following the high-speed rail. It has many advantages such as low energy consumption, high speed, strong climbing ability, safety, intelligence, and comfortable ride. development trend. Therefore, as the first choice for the development of a new generation of ground transportation in the future, maglev trains have great strategic significance for social livelihood, economic development, and urban layout. [0003] There are many methods of speed measurement and positioning technology for maglev trains at home and abroad, such as: cross-loop speed measurement and positioning, Doppler...
