Abstract
This paper presents a Typhoon-induced Vibration Measurement System based on wireless sensor networks for the application of super-high building Structures vibration inspection. The designed system consists of intelligent acquisition equipment and 8 wireless nodes with low-frequency acceleration sensor. The whole system has 64 collection channels, namely every wireless collection node has eight 16-bit A/D channels. Wireless node, integrated with vibration sensing unit, embedded low-power micro-processing unit, wireless transceiver unit, large-capacity power unit, and GPS time synchronization unit, can finish the functions such as data collection, initial analysis, data storage, data wireless transmission. Intelligence acquisition equipment, integrated with high performance computation unit, wireless transceiver unit, mobile power source and embedded data analysis software, can totally control multi-wireless nodes, receive and analyse data parameter identification. To verify the SYSTEM, experiments on the standard horizontal vibration table (shake table III) and super-high building of Diwang Plaza are conducted. Experimental results show that the system has the following characteristics as fast arrangement, high sampling rate, high resolution, capacity of low frequency inspection, and thus has good application prospects and practical value.
