Description
Technical Field
The embodiment of the application relates to the field of rail transit, in particular to a train positioning method, a train positioning device, terminal equipment and a storage medium.
Background
Currently, with the progress of scientific technology and the development of engineering technology, various train positioning technologies, such as an orbit circuit, an odometer, a query/transponder, a velocimeter, a satellite system, wireless communication, an induction loop, and the like, are proposed. However, the existing technology for positioning a train has the following disadvantages:
(1) The positioning of the train based on the track circuit has the disadvantage that the positioning accuracy depends on the length of the track circuit, and the positioning is not accurate enough to form a moving block.
(2) Train positioning based on inquiry/transponder is the most widely used mode in rail transit, but has the disadvantage that only point type positioning information can be given, the contradiction between the setting interval and the investment scale exists, and currently, a hybrid positioning method, namely, train positioning based on speed measurement is generally adopted to inquire/transponder to correct accumulated errors caused by wheel diameter change, slipping or idle running.
(3) The train positioning technology based on wireless communication is a new positioning technology and is a mobile block positioning method based on advanced communication technology and computer technology. By arranging radio equipment on the train and beside the track, the real-time positioning of the train is realized by utilizing advanced wireless communication and computer information processing technology. The method has the advantages of accurate positioning, but has the defects of high investment cost because a special spread spectrum base station needs to be arranged along the line.
(4) The train positioning based on the induction loop is that when the train passes through each cable crossing point, the vehicle-mounted equipment detects the polarity change of the signal in the loop and counts the frequency of the polarity change, so that the distance of the train passing through is determined, and the purpose of positioning is achieved. The positioning method is also affected by the length of the crossing area, and if the crossing area is narrow, the possibility of position pulse leakage counting is high, and the positioning accuracy is low.
In summary, how to realize real-time positioning of the train position under the condition of low cost becomes a technical problem to be solved in the present technology.
