Device and method for detecting service quality of subway train operation

Abstract

The invention discloses a subway train operation service quality detection apparatus and a method thereof. The apparatus comprises a detection unit, a detection host and a processing unit, wherein the detection unit includes an inertial measurement module and the detection unit is used for collecting a train body operation attitude parameter, a noise in a carriage, a temperature, humidity, air quality and a mobile phone signal intensity; the detection host is connected to the detection unit in a communication connection mode and is used for acquiring data collected by the detection unit; and the processing unit is connected to the detection host in the communication connection mode, and is used for receiving and storing data transmitted by the detection host, calculating a position parameter of a subway line where the detection apparatus is located according to the data, carrying out single index and integration index evaluation on subway train operation service quality, and carrying out data contrast analysis, data trend analysis, space position analysis, line equipment association analysis and subway line track disease analysis. In the invention, space positioning precision of subway train operation service quality analysis evaluation and objectivity of an analysis result are increased, and a convenient technology means is provided for subway train service quality management and monitoring.

Description

technical field [0001] The invention relates to the technical field of rail transit operation management, in particular to a device and method for detecting service quality of subway train operation. Background technique [0002] Service Quality in a general sense refers to the sum of the characteristics and characteristics of a service that can meet the specified and potential needs, and refers to the degree to which the service work can meet the needs of the serviced. [0003] The service quality of subway train operation refers to the degree to which passengers can meet the requirements of functionality, timeliness, safety and comfort during the process of riding a subway train. [0004] The subway line equipment management department is responsible for the maintenance and repair of subway line equipment. Since the quality of subway line equipment directly affects the service quality of subway train operation, the subway line equipment management department must also accu...

AI Technical Summary

Problems solved by technology

[0006] 1) The detection index is single, and one type of equipment only detects one type of detection item;

[0007] 2) The accuracy of the detection indicators of the equipment is uneven, and the difference is large;

[0008] 3) The positioning accuracy of the detection data is not enough, and most equipment positioning parameters can only be manually calibrated

At present, the line positioning of portable detection equipment on trains usually uses GPS, RFID, and train communication methods. In the subway environment, there are certain problems: GPS signals cannot be received in the underground tunnel environment, and positioning parameters cannot be obtained normally; RFID needs to install electronic tags along the subway line, which is costly; communication with trains requires installation of communication equipment on trains, which involves cost and coordination with train manufacturers; the latter two cases are inconvenient for third-party monitoring

[0010] 1) Each test equipment only evaluates one test item, and the factors affecting the service quality of subway train operation are not considered comprehensively, and the analysis results are not objective enough;

[0011] 2) The detection equipment is limited by the storage capacity, and generally only stores the detection data once, and cannot compare and analyze multiple historical detection data, which is inconvenient for data verification;

[0012] 3) Existing evaluation methods generally evaluate the service quality of subway trains on the entire line or a single line section. The positioning accuracy of the evaluation results is not enough, and it is difficult for the management department of subway line equipment to carry out targeted work to improve and enhance the quality of subway trains.
