Track traffic operation and maintenance system and method

Abstract

The embodiment of the invention provides a track traffic operation and maintenance system and method. The system comprises a trackside terminal and a vehicle-mounted terminal. The trackside terminal is arranged on one side of a track and comprises a vibration sensor, a controller and a detection unit, wherein the vibration sensor is used for collecting the vibration data of the ground, the controller is in communication connection with the vibration sensor and is used for judging whether a track vehicle arrives or not according to the vibration data and sending out a detection instruction if the track vehicle arrives, and the detection unit is in communication connection with the controller and is used for acquiring and sending the track state data according to the detection instruction. The vehicle-mounted terminal is arranged on the track vehicle, is in communication connection with the trackside terminal and is used for receiving and storing the track state data. According to the track traffic operation and maintenance system of the embodiment, the cost can be reduced, inconvenience brought by data reporting can be avoided, and the capability of flexibly deploying track information sampling points is enhanced.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a rail transit operation and maintenance system and method. Background technique [0002] For track operation and maintenance, the steps of collecting track information, analyzing track information, and taking corresponding measures are often used in the field. [0003] For the collection of track information, various methods are adopted in the prior art. However, limited by factors such as power supply, communication, and equipment costs, most of the information collection modules are set not far from the workstations, and flexible deployment of test points cannot be achieved. [0004] On the other hand, when the information collection module is working, it usually adopts a clock timing sampling method, that is, parameters are collected at regular intervals. This method will lead to at least the following defects: [0005] 1. The collected information cannot be reported ...

AI Technical Summary

Problems solved by technology

[0005] 1. The collected information cannot be reported in time, so the information collection module needs to be equipped with a corresponding storage device to store a large amount of data generated by sampling, which increases the cost of the information collection module;

[0006] 2. Clock sampling consumes a lot of power, and usually only wired power supply can be used, which limits the flexible deployment of sampling points;

[0007] 3. For the information collection module set far away from the workstation, the data cannot be reported by short-distance communication, but can only be reported by remote communication or manual data collection. The former further increases power consumption and cost; while the latter increases Reduced labor costs, on the other hand, it brings inconvenience to the acquisition of sampling data

[0008] In addition, due to the accuracy of existing positioning technologies (such as GPS positioning, etc.), when the information collection module is set far away from the workstation, it is often difficult to collect accurate positioning data, which brings great inconvenience to the operation and maintenance of rail transit. inconvenient

[0009] Therefore, how to propose a system that can completely or partially overcome the defects of inconvenient rail transportation operation and maintenance in the prior art has become a technical problem to be solved urgently
