Abstract EN
High-speed railways (HSRs) have been widely deployed all over the world in recent years and China has entered an era with both high investments and rapid expansion of HSR transport infrastructure.
One of the most challenging issues is how to keep the security and safety of millions of HSR infrastructures.
Meanwhile, the emerging sensing and wireless sensor network (WSN) technologies for infrastructure health monitoring (IHM) are being substituted for traditional tethered monitoring systems.
This paper presents a two-layer architecture of WSN which will be appropriate for infrastructure health monitoring of HSR.
The upper layer is named as tree access network and the lower layer is called star detection network.
By adapting to the special characteristics of IHM network, we design a short network address and an optimized communication frame structure, which can satisfy the actual requirements and special characteristics of the IHM network.
In order to implement a better transmission performance, we propose a novel transmission power based method which adopts the knowledge update mechanism to detect the optimization result.
In the end, the details of address assignment and network construction are discussed, and the effectiveness of the proposed method is validated by a practical instance.
