Problems solved by technology
Among them, satellite positioning cannot be used in tunnel lines and some elevated platforms
As an important device in the field of aerospace technology, the cost of high-precision inertial navigation devices is high, and the technical application is complicated. However, under the existing technical conditions, inertial navigation devices used for general industrial or consumer electronics are used for long-term (uniform speed) operation and low-frequency For mobile carriers with many interference signals, such as urban rail transit vehicles, due to the influence of interference, drift and cumulative errors, the actual measurement results of acceleration and speed are limited

A method for measuring the daily running state of urban rail transit vehicles relates to the technical field of rail transit and solves the technical problems of poor reliability and high implementation cost of existing methods. The method uses an acceleration sensor to measure the first acceleration component and the second acceleration component of the vehicle, and judges the running state of the vehicle according to the measured values. The first acceleration component of the vehicle refers to the acceleration component perpendicular to the direction of travel of the vehicle, and the first acceleration component Represents the vibration of the vehicle. The second acceleration component of the vehicle refers to the acceleration component parallel to the direction of travel of the vehicle. The second acceleration component represents the acceleration and deceleration of the vehicle in the direction of travel. The method provided by the invention is suitable for monitoring the daily running status of urban rail transit vehicles.
Description
technical field [0001] The invention relates to rail transit technology, in particular to a method for measuring the daily running state of urban rail transit vehicles. Background technique [0002] When the existing urban rail transit line is in operation, the vehicle or train control center can obtain various daily operating states of the vehicle through the automatic train control system and image acquisition and processing system, including the vehicle's starting, driving, parking, vehicle speed, mileage, location, etc. Location, passenger flow situation, vehicle turn-back situation, etc. However, the above-mentioned operating status needs to be obtained through a combination of multiple subsystems and equipment through various means. Once the relevant equipment fails, many basic daily operating status cannot be obtained in time. [0003] In addition, many in-vehicle systems or devices need to independently obtain some basic operating states of the vehicle at a relative...
