Problems solved by technology
However, the disadvantage of satellite navigation and positioning is that if the satellite signal is blocked, such as in a tunnel, positioning cannot be performed
[0008] From the above analysis, it can be seen that the following problems usually occur in the current positioning methods and systems: relatively large positioning errors, high costs, inability to perform positioning in some environments, and some solutions can only be positioned intermittently and cannot be positioned continuously, such as track circuit

The embodiment of the invention relates to the field of rail vehicle positioning, and provides a rail vehicle positioning method and system. The rail vehicle positioning method comprises the followingsteps: detecting the number of rail fasteners passed by a rail vehicle during running ; and calculating the driving distance of the rail vehicle based on the detected number of the rail fasteners. The rail vehicle positioning system can at least solve the problem of continuous positioning of the train in a tunnel, and is high in positioning precision, stable in effect, low in cost and convenientto maintain.
Description
technical field [0001] The invention relates to the field of rail vehicle positioning, in particular to a rail vehicle positioning method and system. Background technique [0002] The train positioning system is an important part of the train operation control system. The train speed and mileage provided by the train positioning system are the basic parameters to realize the effective control of the train. Whether the positioning information is accurate and reliable directly affects the safety and operation efficiency of the train. With the rapid development of my country's railways, the train positioning technology has become one of the key technologies of the train operation control system. Commonly used train positioning technologies generally include the following categories: [0003] Odometer: It is usually installed on the non-powered wheel shaft (speed wheel) of the vehicle. It calculates the real-time speed and distance of the train by detecting the number of wheel ...
