At present, study on on-board wireless sensor network of trains has not drawn sufficient attention. Existing wireless sensor network is still flawed in aspects such as topological structure, construction environment, and routing protocol and thus is not desirable for riding comfort detection. A new double-level mixed topological structure which is oriented to high-speed train is illustrated in this paper. This structure is designed based on analysis on the topological structure of wireless sensor network with the consideration of the complex riding environment of the high-speed railway in China. Analysis indicates that this multi-level topological structure increases the bandwidth of data transmission path. In addition, it increases the stability of network, especially for highly reliable section, by a range from 6.9 to 37.5 % than traditional structure. This structure fulfills the requirement for fast and stable transmission of on-board detection network and is provoking in communication network structure design of on-board equipment.
