Abstract

Provided is an in-depot examination device for center node equipment. A protocol analysis module, a data encoding and decoding module and a man-machine interaction module are connected to display to in-depot examination personnel the current working state, fault and other related equipment information returned by a piece of examined center node equipment. A data communication module adopts a standard network data transmission protocol, and is connected with an auxiliary maintenance system of the center node equipment to realize data link building. A data storage module stores the examination process and equipment examination information. A center node equipment end self-examination module is a sub function module of the auxiliary maintenance system of the center node equipment, and the function module can complete internal self-examination on the functions of internal units of the center node equipment and return self-examination results. By adopting the in-depot examination device, hidden faults of the center node equipment can be timely diagnosed and found, the work efficiency of active examination can be improved, the cost of equipment maintenance can be reduced, the operation safety of urban rail vehicles can be improved, and the occurrence of equipment failure can be prevented.

Description

technical field [0001] The invention relates to a library inspection device for central node equipment, which realizes the detection of the working status and fault points of the central node equipment by the library inspection device, and the library inspection device matched with the central node equipment can perform one-to-many The detection and information management of the central node equipment, the storage inspection device and the central node equipment are used together, and belong to the field of modern rail transit technology. Background technique [0002] In the existing technology, the train inspection personnel cannot quickly locate the location of the fault in the event of equipment failure; the central node equipment, library inspection terminal and other network terminal equipment connected to the central node equipment will be affected due to the performance of the network connector and the transmission rate of the equipment. Under the influence of the env...
