Embodiment Construction

[0071] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0072] The following takes the railway track monitoring sensor node 1 as an example to illustrate the reasons for loading and starting the firmware of the railway track monitoring sensor node.

[0073] In two cases the railway track monitoring sensor node 1 can be loaded with a new firmware version.

[0074] (1) When the railway track monitoring sensor node 1 requests access to the railway track monitoring sensor access multiplexing device 1, the railway track monitoring sensor node network access response message responded by the railway track monitoring sensor access multiplexing device 1 Contains a version identifier information element, which indicates the firmware version that needs to run on the railway track monitoring sensor node 1. If there is no firmware version indicated by the version identifier information element on the rai...

Abstract

The invention relates to the technical field of information and communication and in particular relates to a remote firmware loading method for a railway track monitoring sensor node. In order to reduce the running maintenance load of a railway track monitoring and sensing network, railway track monitoring and sensing access multiplexing equipment and the railway track monitoring sensor node both need to support a remote firmware loading function, thus reducing the maintenance burden generated in upgrading the firmware version of the equipment. The invention provides a remote firmware loading method for the railway track monitoring sensor node, thus assisting the railway track monitoring sensor node to automatically load new firmware version from the railway track monitoring and sensing access multiplexing equipment; and the railway track monitoring and sensing access multiplexing equipment can also carry out dynamic updating on a firmware version program running in the railway track monitoring sensor node at any time in a network running process.

Description

technical field [0001] The invention relates to a communication network, in particular to a remote firmware loading method for a railway track monitoring sensor node 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 sensors to perceive enviro...
