Measurement method for daily operation state of urban rail transit vehicle

Abstract

The invention discloses a measurement method for a daily operation state of an urban rail transit vehicle, relates to the technical field of rail transit, and aims to solve the technical problems of poor reliability and high implementation cost of the conventional method. According to the method, a first acceleration component and a second acceleration component of a vehicle are measured by using an acceleration sensor, and the operation state of the vehicle is judged according to the measured values, wherein the first acceleration component of the vehicle indicates the acceleration component perpendicular to the vehicle heading direction; the first acceleration component represents the vibration condition of the vehicle; the second acceleration component of the vehicle indicates the acceleration component parallel to the vehicle heading direction; the second acceleration component represents the speed-up and speed-down condition in the vehicle heading direction. The method provided by the invention is applicable to monitoring the daily operation state of the urban rail transit vehicle.

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...

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
