Detection diagnosis system and diagnosis method for railway intranet based on LKJ

Abstract

The invention relates to a detection diagnosis system and diagnosis method for a railway intranet based on LKJ, and belongs to the technical field of diagnosis devices and methods. The system comprises a ground operation end and a client. The system can achieve the real-time alarm and display of various types of hidden quality problem information of equipment through the retrieval analysis of an LKJ operation file, and can timely guide a detector to carry out the inspection and processing timely, thereby improving the detection efficiency, and solving an equipment quality problem caused by delayed analysis. A system transmits the edition information to a ground data server through a CDMA network, employs a mode that a diagnostic apparatus is provided with an LKJ data exchange plane in advance, achieves the redundancy diagnosis function of the LKJ data edition of a hand-held diagnostic apparatus and the ground server, and guarantees the accuracy of the LKJ edition. The system achieves the change of detection operation process control from manual control to machine control, and fundamentally guarantees the warehousing quality of equipment.

Description

technical field [0001] The invention relates to a detection and diagnosis system and a diagnosis method of a railway intranet based on LKJ, and belongs to the technical field of diagnosis devices and methods. Background technique [0002] The train operation monitoring device (LKJ for short) is an integral part of the train operation control system. It is an important driving equipment used to prevent the train from rushing into the signal, running overspeed accidents and assisting the locomotive driver (including the EMU driver) to improve the control ability. LKJ is a component of locomotives and EMUs. [0003] Since LKJ adopts the vehicle-mounted data storage method, LKJ data changes caused by ground line construction and line speed limit adjustment will inevitably increase the workload and safety hazards of LKJ vehicle-mounted equipment data replacement. On the other hand, with the railway transportation System reform, long-distance roads and changes in single-driver du...

AI Technical Summary

Problems solved by technology

[0004] In the past, the standardization of LKJ's inbound and outbound inspection operations relied entirely on the operator's self-consciousness and management personnel's post-supervision. It was impossible to realize the intelligent diagnosis of LKJ's equipment operation quality and real-time analysis of inspection and inspection standards, and there were problems of missed inspections and repairs. It is impossible to use technical means to realize the transformation of inspection process control from "man-controlled" to "machine-controlled", nor can it fundamentally guarantee the quality of equipment entering and leaving the warehouse
