PROBLEM TO BE SOLVED: To efficiently measure a heartbeat only in timing appropriate for cardiotachometry.SOLUTION: A cardiotachometry control device comprises: an acceleration data acquisition part 21 that acquires acceleration data detected by an acceleration sensor 11 for detecting an animal's movement; a determination part 24 that determines a time zone, in which the animal hardly moves, as a period of measurement time, on the basis of the acceleration data acquired by the acceleration data acquisition part 21; and a measurement control part 25 that measures the animal's heartbeat by controlling a heartbeat sensor 12 attached to the animal, on the basis of the period of measurement time determined by the determination part 24.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】心拍の測定に適したタイミングに限って、効率的に心拍を測定すること。【解決手段】動物の動作を検出する加速度センサ11が検出した加速度データを取得する加速度データ取得部21と、加速度データ取得部21が取得した加速度データに基づいて、動物の動作が少ない時間帯を測定時間として判定する判定部24と、判定部24が判定した測定時間に基づいて、動物に装着された心拍センサ12を制御して動物の心拍を測定する測定制御部25とを備える。【選択図】図1
