Development of Sensor Unit for Extraction/Transmission of Only Peak Acceleration Response
This paper presents the sensor units which are developed to store autonomously only the acceleration peak value data and the basic scheme of sending those data to the web server. The developed sensor unit consists of Raspberry Pi 3B, digital MEMS accelerometer and Low Power Wide Area (LPWA) network device. Having the transmitted data volume limitation, LPWA network device advantageously enables long-distance communication with such a low power as can be operated on the battery. The proposed algorithm associated with the developed sensor unit would be able to extract the peak absolute acceleration response of a structure to every single earthquake. The sensor unit implemented into each building would transmit the peak absolute acceleration response as well as the basic structural information (such as structure type and fundamental frequency) to the web server utilizing LPWA network device. The developed sensor unit would provide the useful information for estimating the damage situation in the area in which the building is located. The proposed sensor unit has been tested utilizing the opportunity of full-scale steel hospital building shake table experiments at the E-Defense.
