PROBLEM TO BE SOLVED: To provide an environmental control program for controlling a cultivation environment or the like according to change of tidal power, using gravity acceleration as an indicator of tidal power.SOLUTION: The present invention provides an environmental control program for controlling an environment in accordance with tidal power. The environmental control program comprises: an extreme time detection function for detecting, as a maximum time or the like, all times at which a change in gravitational acceleration assumes a maximum value or the like within a predetermined period and a change amount calculation function for calculating, as a rise amount, a value obtained by subtracting the value of the gravitational acceleration at a minimum time or the like just before that from the value of gravitational acceleration at the maximum time or the like, for each maximum time or the like. The environmental control program further comprises a maximum information generation function for generating control information to specify environmental control at the maximum time or the like, on the basis of a result of comparison obtained by comparing, for each maximum time, the rise amount at the maximum time or the like and the rise amount at each maximum time or the like immediately before and after that.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】起潮力の指標として重力加速度を用い、起潮力の変化に応じて育成環境等の制御を行うための環境制御プログラムを提供する。【解決手段】本発明は、起潮力に応じて環境の制御を行うための環境制御プログラムであって、所定の期間において、重力加速度の変化が極大値等となる全ての時刻をそれぞれ極大時刻等として検出する極値時刻検出機能と、極大時刻等毎に、当該極大時刻等における重力加速度の値からその直前の極小時刻等における重力加速度の値を差し引いた値を上昇量として算出する変化量算出機能と、を備え、更に、極大時刻等毎に、当該極大時刻等の上昇量等と、その直前及び直後の各極大時刻等の上昇量等とを比較した比較結果に基づいて、当該極大時刻等における環境制御を指示するための制御情報を生成する極大情報生成機能等を備える。【選択図】図1
