Abstract

The invention discloses the track traffic information network detection technology field and relates to a city specified traffic train safety information sensing network structure and a parameter simulation and test method. The sensing network structure comprises two data centers respectively mounted on two heads of a train and multiple composite nodes, wherein each composite node comprises n access nodes, the composite nodes are mutually connected, the composite nodes and the access nodes are mounted in a cabinet in each carriage, and each access node comprises multiple sensors. The sensing network parameter simulation and test method is further proposed. The device is advantaged in that the system is complete, functions are rich, the simulation technology with different transmission rates, throughout and transmission delays and the test technology can be realized, the sensor network performance is comprehensively mastered, transmission performance is optimized, and sources are reasonably utilized as bases.

Description

technical field [0001] The invention belongs to the technical field of rail transit information network detection, and in particular relates to a simulation and testing method for the structure and parameters of an urban rail transit train safety detection sensor network. Background technique [0002] As one of the main transport carriers of large-capacity urban public transport, rail transit is extremely important and critical to the entire public transport network to ensure its safe, efficient and reliable operation. Rail transit safety monitoring sensor network plays a vital role in the operation, management, maintenance and safety guarantee of rail transit trains and stations, and is an important guarantee measure for rail transit safety. It monitors the key components of rail trains, the service status of ground infrastructure, the operation of platform infrastructure, the changes of passengers, and the station environment, and uses the network to realize the status of ...
