Embodiment Construction

[0029] Such as figure 1 Shown is the network topology diagram of the system of the present invention, and its realization principle is exactly that vehicle control module 5 realizes the data communication between man-machine interface 2 (also called man-machine interface or HMI) and incident recorder 1 through MVB bus 4, thereby will The download operation instruction performed by the maintenance personnel on the man-machine interface 2 is forwarded to the event recorder 1, and the relevant download status information fed back by the event recorder 1 is sent to the man-machine interface 2 for display. The event recorder 1 can also directly read the sending port data of the man-machine interface 2, and the man-machine interface 2 can also directly read the sending port data of the event recorder 1. But generally all transfer through the vehicle control module 5 .

Abstract

The invention discloses a data visual downloading control system and method based on a network embedded system, the data visual downloading control system comprises an event recorder, a man-machine interface and a USB flash disk, the event recorder is provided with a port used for being connected with the USB flash disk, and the event recorder is connected with the man-machine interface through anMVB bus; the man-machine interface is provided with a downloading interface; the event recorder is used for sending a record marking signal and capacity corresponding to a data block to the man-machine interface when the data block is generated; and also used for downloading the data block information into the USB flash disk after receiving a downloading operation instruction; the man-machine interface is used for displaying the data block generation state, the capacity, the recording time and the downloading control on the downloading interface after receiving the recording marking signal and the capacity; and also used for sending a downloading operation instruction to the event recorder after the downloading control is clicked. Locomotive data can be downloaded at any time, locomotivedata information can be conveniently obtained in time, and troubleshooting can be conveniently, rapidly and effectively carried out.

Description

technical field [0001] The invention belongs to the technical field of railway transportation, and in particular relates to a data visual download control system and method based on a network embedded system. Background technique [0002] At present, locomotive maintenance personnel obtain locomotive running status or fault data information by using a laptop computer to connect to the event recorder and downloading with TDS software. At present, each event data block of the event recorder is about 100M. When the event recorder is full, the first-in first-out operation is performed on the event data blocks. [0003] The existing operation mode requires a notebook computer and TDS software tools to download data, which is not conducive to timely acquisition of data. When the locomotive has a major problem, if the data cannot be obtained in time, it is not conducive to quickly and effectively troubleshooting the vehicle. Contents of the invention [0004] The object of the ...
