Abstract:

The paper introduces the technical features of the railway track inspection cars of different countries and the development review of China’s technology of railway track inspection, and make a brief comparison of the advantage and disadvantage between the chord measurement and Inertial method. The paper also introduce the integrated detection system, which consists of a laser visual detection system, laser radar scanning technology, infrared thermal imaging technology , radar technology and communication detection system. With the implementation of the railway transport, enhanced efforts should be exerted to the comprehensive checking of the track. The development orientation and application of subway inspection equipment is put forward. To develop new portable track inspection cars which can detect the railway tracks and tunnels and the quality of the transmission channel of the train control information, the strength of wireless mobile communication system and track’s electromagnetic environment at the same time.
