Study on Monitoring Method Using a Wrist Watch Type Device for Unsafe Behavior

摘要

If it's construction business, it's being talked about that there are most dead accidents in all the industries, and establishment of effective safety training is wished for. Various devices such as the occasion in which steel fell actually at a construction site and the interactive safety training which assumed the case when a worker fell are taken in it. But there is no end to accident by worried whole behavior caused by oversight, an attentiveness lack, a dangerous slight and accustoming. So the mechanism to aim at concentration to worker's work by this research and monitor the worried whole behavior which tends to happen at the time of non-concentration using a simple device was considered. Specifically, the state that a wrist type device with a sphygmograph was loaded It was so and I worked and acquired time series data of a pulse in real time. I calculated the feature quantity of the integration value and the finite difference value from acquired data, inspected about concentration to work and relationship with a pulse based on its value and considered the monitoring technique of the pulse pattern when not concentrating.
