Dynamic wheel speed train detection system

The present application provides a high-speed train wheel dynamic testing system, acquired by the track detection means of the rail wheel is mounted on two opposing inner side tread condition detection signal, and the side rails connected thereto by means of the detection switching signal field to a processing device, whereby the field by the processing apparatus PC, the detection signals are processed to determine the current detection result of the wheel train, and displayed, the site personnel to timely display of a train operation to be adjusted to ensure the traffic safety of the train, in which, since the upper rail detecting device of the present invention is provided in the inside of two opposing rails, when installed, without the need for destructive transformation of the rail, and, on the rail internal detection means associated device earthquake resistance, it is possible to obtain information obtained in the high-speed train train running, moreover, the wheels of the train detection system line detection process is completely automatically improve the detection efficiency.
