Embodiment Construction

[0032] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, in the railway track monitoring sensor network, the railway track monitoring sensor network controller is the core control device of the entire railway track monitoring sensor network, responsible for all the railway track monitoring sensor access multiplexing equipment in the network control management. The railway track monitoring sensor network controller 1 and the railway track monitoring sensor network controller 2 are mutually active and standby control devices, and jointly manage the railway track monitoring sensor network. The railway track monitoring sensor network controller 1 is the main control device. When the railway track monitoring sensor network controller 1 fails, all the railway track monitoring sensor access multiplexing devices will start to control the railway track monitoring senso...

Abstract

The invention relates to the technical fields of information and communication and in particular relates to a single point of failure protection method and device of a railway track monitoring and sensing network. In order to prevent single point fault of networking equipment in the railway track monitoring and sensing network from causing network failure, the invention provides the single point of failure protection method and related device of the railway track monitoring and sensing network. Through adopting a main / standby railway track monitoring and sensing network controller and main / standby railway track monitoring and sensing access multiplexing equipment in the railway track monitoring and sensing network, the standby equipment works instead of the main equipment when the main equipment has fault, thus ensuring the ceaseless running of the railway track monitoring and sensing network, and preventing the single point fault of networking equipment in the railway track monitoring and sensing network from causing network failure.

Description

technical field [0001] The invention relates to a communication network, in particular to a single-point failure protection method and device for a railway track monitoring sensor network in a railway track monitoring sensor network. Background technique [0002] As the speed of railway transportation continues to increase, the requirements for the safety of railway tracks are also getting higher and higher. The timely acquisition of various parameters of railway tracks, such as: rail temperature, rail stress, track settlement, track deformation, etc., will help It is used to accurately judge the status of the rails, control the speed of the train, and ensure the safety of railway transportation. However, due to the large range of railway track monitoring and the harsh environment, there is no suitable technical means to solve the problem of real-time monitoring of large-scale railway track parameters. [0003] Wireless sensor network technology can use ultra-low power sens...
