TEDS
In order to ensure the safe and stable operation of the motor train unit, trouble of moving EMU diction system (TEDS) can automatically collects and analyzes the images of the running gear, brake parts, undercarriage suspension parts, coupler connection, skirting boards on both sides of the train, bogie, wheel tread, flange, rims etc. of the motor train unit by installing linear array and area array combined camera. It can give an alarm of different degrees when the images are unusual. At the same time, with the help of images transmission and processing technologies, it can timely transfer the unusual high-capacity images and alarms to the alarming terminals local or remote trains with a little occupation of network bandwidth. People only need to affirm the alarming information, which greatly reduces the number of the dynamic working staff and time and improve the safety level of the operation of motor train units.
At present, TEDS has already passed the technical reviews of Wuhan Railway Bureau (technical review of WRB, document No.: [2010]003) and Shenyang Railway Bureau (technical review of SRB, document No.: [2011]014) and is listed as one of the managements of safety and risk of Railway Bureau. (Vehicle transport station, check letter No.: [2012]122)

TEDS can be divided into two types according to its application environment and functions: TEDS-H and TEDS-L. TEDS-H is mainly used for the online parts detection of long routing and pull back trains and is installed in the front of pulling in station, which is helpful for the discovery and treatment of troubles in advance. The system fits the trains with the speed of 5-200 kilometers/h. This system has already installed in Shenyang Railway Bureau.
TEDS-L is mainly used for the comparison of the parts conditions when pulling out and the standard parts conditions of the trains, which can improve the quality of trains pulling out. The system adopts high definition color cameras and the parts conditions are clearer. It adopts the combination style of linear array and area array and has more complete functions and it can make a comprehensive and multi-angle detection of the bottoms, skirt board and wheel tread of the trains. It fits the trains with the speed of 5-20 kilometers/h, especially for the detection of wheel tread and rims, it can completely remove the blind areas of visual check after it pulls in and improve the discovery ability of troubles. The system has already been put in use in Wuhan Railway Bureau.
