To provide a work machine control system and a work instruction device for preventing a power failure state of an automatic work machine, even when a power supply device that charges the automatic work machine uses a secondary battery that is charged by a natural energy power generation device in which generated power depends on weather.SOLUTION: A work machine control system (1) includes: an automatic work machine (2) that has a first secondary battery (9); a power supply device (3) that charges the first secondary battery from a second secondary battery (12) supplied with power by a natural energy generation device (11); and a work instruction device (4) that transmits a work instruction to the automatic work machine, wherein the work instruction device includes a work planning unit (75) that creates a work instruction including an operation time zone during a work scheduled period, and the work planning unit determines the operation time zone based on a power consumption forecast which is the time transition of the power consumption of the automatic work machine, and an energy generation forecast which is the time transition of an amount of natural energy generated during the work scheduled period, so that a charge remaining amount of the second secondary battery transits within a range equal to or greater than a first predetermined value.SELECTED DRAWING: Figure 4
【課題】自動作業機に充電する給電装置が、発電電力が天候に依存する自然エネルギー発電装置により充電される二次電池を用いる場合でも、自動作業機の電源喪失状態を回避する。【解決手段】作業機制御システム(1)は、第1の二次電池(9)を備える自動作業機(2)と、自然エネルギー発電装置(11)により給電される第2の二次電池(12)から第1の二次電池に充電する給電装置(3)と、自動作業機に作業指示を送信する作業指示装置(4)と、を有し、作業指示装置は、作業予定期間における稼働時間帯の指定を含む作業指示を作成する作業計画部(75)を備え、作業計画部は、自動作業機の消費電力の時間推移である消費電力予測と、作業予定期間における自然エネルギーの発生量の時間推移であるエネルギー発生予測と、に基づいて、第2の二次電池の充電残量が第1所定値以上の範囲で推移するように稼働時間帯を決定する。【選択図】図4
