A design of multi-channel wireless sensing system for structural monitoring

Abstract eng:
Wireless communication is a promising technology which is willing to substitute the traditional wired communication in the areas of sensing and monitoring, with advantages especially for large-scale structural health monitoring systems. Since there are many existing wire-based sensing systems, in order to update these systems to become wireless without much cost and significant changes, this paper is devoted to design a kind of wireless transmission system for analog signals of sensors, which can be used to replace the wire signal. This system mainly consists of one central receiver, and several wireless sensing units which all communicate with the central receiver on different frequency channels simultaneously to acquire signals of high sampling rate and low lantency. The low-power features are also considered and the feasibility of supplying power by batteries is investigated. Lastly, the performance of the transmitter designed for such a system will be verified by experiments.
