Embodiment 1

[0053] An urban rail train safety detection sensor network test system,

[0054] (1) Design the architecture of the system of the present invention by analyzing the rail transit safety monitoring sensor network;

[0055] The system of the present invention should have the following functions: the data of the test equipment can be transmitted to the data center through a dedicated network, and will not occupy the bandwidth of the tested network; all indicators of the basic network can reach the world-class level; The basic network can support arbitrary changes in the network form, such as the increase and decrease of the number of nodes in the network, changes in the network topology, etc.; through certain means, the basic network needs to have the ability to reduce its own parameters, such as increasing network delay and reducing bandwidth , the nodes in the wireless sensor network can forcibly change the reference clock and so on.

[0056] In order to meet the above requirem...

Embodiment 2

[0099] On the basis of the construction of the urban rail train safety detection sensor network test system, the steps for the test network to be used for basic network testing:

[0100] ① Simulate the external environment

[0101] The urban rail train safety detection sensor network test system can simulate a variety of traffic operating environments, including the simulation of various noises and interferences in the traffic environment, the simulation of sensor data, the attack simulation of each layer of the sensor network, wireless sensor Location situation simulation. The system can record the operating status and environmental characteristics of the network in all environments. To realize the above simulation, the following systems need to be constructed:

[0102] ●Noise and interference simulation system

[0103] This system is divided into two parts according to the communication mode, wireless channel interference simulation and wired channel occupation simulation...

Abstract

The invention relates to a system and a method for testing an urban rail train security detection sensing network and belongs to the technical field of rail traffic security in-transit monitoring technologies. The system comprises a basic network (BN) and a test network (TN). The basic network is a test object built for the system. The test network tests the basic network through the built network. The basic network comprises a data center, compound nodes, access nodes and various types of sensors. The test network comprises a center master control server (Center PC), a client-side server (SimPC), a test network switch (TN Switch) and a disk array device. The testing method is divided into a whole network performance testing method, a local network performance testing method and a node performance testing method. By adopting the system and the method for testing the urban rail train security detection sensing network, formation of an urban rail train networked in-transit fault monitoring and early-warning technique and a device system which are compatible with the situation and conditions in China is facilitated, the urban rail traffic security guarantee level in China is updated, and a fundamental and global technology and device support is provided for sustainable development of urban rail traffic in China.

Description
