Embodiment Construction

[0036] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0037] figure 1 A schematic structural diagram of an embodiment of a data recorder provided by the present invention. Such as figure 1 As shown, the data recorder of this embodiment mainly includes: a central processing module 1 , a data storage module 2 and an HDLC interface module 3 . Among them, the data storage module 2 is used to store the data that the data recorder needs to save; the central processing module 1 is used to receive data from the HDLC bus 4 through the HDLC interface module 3, process the data and send the processed data to the data The storage module 2 and the HDLC interface module 3 are used to receive data from the HDLC bus 4 and transmit the data to the central processing module 1 .

[0038] Specifically, the HDLC interface module 3 is connected to the HDLC bus 4 on the locomotive, and the HDLC interface module 3 receives data from t...

Abstract

The invention provides a data recorder based on HDLC (high-level data link control) and a recording method. The data recorder comprises a central processing module, a data storage module and an HDLC interface module, wherein the data storage module is used for storing data to be stored by the data recorder; the central processing module is used for receiving the data from an HDLC bus through the HDLC interface module, processing the data and sending the processed data to the data storage module; the HDLC interface module is used for receiving the data from the HDLC bus and sending the data to the central processing module. According to the data recorder provided by the invention, the problems in the prior art are solved; running data and fault data of a locomotive using the HDLC bus can be recorded in real time, so that a worker can perform immediate and quick analysis and remove faults.

Description

technical field [0001] The invention relates to rail transit technology, in particular to an HDLC-based data recorder and recording method. Background technique [0002] Data recorder is a device used to record vehicle operation data and fault data, which is widely used in rolling stock. During use, maintenance personnel can promptly and quickly eliminate vehicle faults by analyzing the data recorded on the data recorder. [0003] The High Level Data Link Control (HDLC for short) protocol is a protocol that is widely transmitted at the data link layer and has high data link transmission efficiency. None of the existing data recorders can be applied to locomotives using the HDLC bus to record the running data and fault data of the locomotive, resulting in many faults that cannot be eliminated in time and quickly. Contents of the invention [0004] The invention provides an HDLC-based data recorder and a recording method, which are used to solve the problem that the existi...
