To provide a system, a method, etc., capable of detecting presence of a person with a small calculation amount.SOLUTION: A presence detection system for detecting presence of a person includes: detection means for detecting a plurality of extreme values from a result of measurement of measurement means for measuring a change in force applied to a seat: calculation means for calculating differential values between temporally adjacent maximum values and minimum values of the detected plurality of extreme values, and calculating a difference between the maximum differential value and the minimum differential value of the calculated differential values as a determination value; and determination means for determining whether a person is present or absent based on the calculated determination value.SELECTED DRAWING: Figure 11
【課題】 少ない計算量で人の在席を検知することができるシステムや方法等を提供する。【解決手段】 このシステムは、人の在席を検知する在席検知システムであり、座席上にかかる力の変化を測定する測定手段の測定結果から複数の極値を検出する検出手段と、検出された複数の極値のうち、時間的に隣り合う極大値間および極小値間の差分値を計算し、計算した差分値のうちの最大差分値と最小差分値の差を判定値として算出する計算手段と、算出された判定値に基づき、在席か不在かを判定する判定手段とを含む。【選択図】 図11
