Problems solved by technology

[0003] However, although my country's rail transit has deployed a large number of monitoring systems, the research on rail transit safety monitoring sensor networks is fragmented and independent. Simulation and testing technology lacks effective and unified standards and methods, so it is urgent to invent a system that is perfect,

Abstract

The invention discloses a method for simulating and testing a structure and parameters of an urban rail train safety detection sensor network in the technical field of rail transit information network detection. The structure of the sensor network comprises two data centers respectively installed on two locomotives of a train and a plurality of composite nodes, wherein each composite node comprises n access nodes, the composite nodes are connected, the composite node and the access nodes are installed in a cabinet inside each compartment. Each access node comprises a plurality of sensors. In addition, the invention further provides a technology for simulating and testing different transmission rates, handling capacities and transmission delays of the train safety detection sensor network which is complete in system and rich in function, comprehensive master of the sensor network performances is achieved, and a steppingstone is made for transmission performance optimization and reasonable resource utilization.

Description

technical field [0001] The invention belongs to the technical field of rail transit information network detection, in particular to a method for simulating and testing the structure and parameters of an urban rail 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 all train equipment,...
