◆ Introduction:

This system adopts the technologies of image deep compression, GPU sub-contract processing, multi-threaded concurrent transmission etc. it optimized transmission structure, transmission speed, and transmission stability without changing the quality of the images. This system can realize narrowband transmission with 2M network access; reduce the cost of access construction and maintenance and shorten the construction cycle; with enough network resource, it can save network bandwidth resource and make more systems to enjoy network bandwidth. This system can also ease the workload of TFDS central distributing car server and solved the problem of sluggish network when getting images. Besides this, this system provides data transmission service for trouble networking tracing, image contrast and trouble alarming.

    Now, this system has already passed the technological assessment organized by vehicle department of Shenyang Railway Bureau (VDSRB) (File No.: [2011]30 VDSRB) and also passed the TFDS intensive working adopting 2M access long-distance transmission program assessment organized by device department of transport bureau in railway ministry. (File No.: [2011]394)

Working procedure of the system

Appearance of the device

◆ Function:

1. It can preprocess of the TFDS images: tailor, rotate, mirror image, scaling etc. which greatly reduces the workload of image processing and transmission and the workload of TFDS central distributing car server; satisfies the instantaneity and stability of the whole intensive working; solved the problem of sluggish when getting the images;

2. Transmission takes only 2M bandwidth resource, which saved network resource and reduced the cost and time of construction;

3. It can realize the connecting between points and frames of TFDS; alarm for TFDS trouble tracing; provide basis for work quality assessment, image comparison and identification;

4. Network self-detection and breaking point continuous transmission;

5. Network double channels for hot switching;

6. 24 hour data hot backup of TFDS train inspection server;
7. Compatible with TFDS data of all types and companies;
8. Automatic monitoring of car-passing message and image synchronous processing.
