PROBLEM TO BE SOLVED: To provide a warning device control method, a warning device controller, a land transportation refrigeration car, and a land transportation refrigeration unit capable of detecting incomplete closing of a protection member or failure to close the protection member even if a refrigeration car travels without actuating a refrigerating machine, while suppressing cost increase.SOLUTION: A warning device controller includes: a vehicle-operation determination unit 9 determining an operation state of a vehicle; a refrigerating-machine-operation determination unit 10 determining an operation state of a refrigerating machine loaded in the vehicle; an open/close determination unit 11 determining an opened/closed state of a protection member that can be opened/closed for protecting control equipment of the refrigerating machine; and a warning device control unit 9 controlling warning display means 14 to display a warning in response to determination of the open/close determination unit 11 that the protection member is opened if the refrigerating-machine-operation determination unit 10 determines that the refrigerating machine is not active and only if the vehicle-operation determination unit 9 determines that the vehicle travels.
【課題】コスト上昇を抑制しつつ、冷凍機を作動させずに冷凍車が運行する場合でも保護部材の不完全閉時や閉め忘れを検知することができる警告装置制御方法、警告装置制御装置、陸上輸送用冷凍車及び陸上輸送用冷凍ユニットを提供することを目的とする。【解決手段】警告装置制御装置は、車両の運転状態を判定する車両運転判定部9と、車両に積載された冷凍機の運転状態を判定する冷凍機運転判定部10と、冷凍機の制御機器を保護する開閉可能な保護部材の開閉状態を判定する開閉判定部11と、冷凍機運転判定部10が停止中と判定した場合は、車両運転判定部9が走行中と判定したときのみ、開閉判定部11が開と判定したときに警告を発するよう警告表示手段14を制御する警告装置制御部9と、を備える。【選択図】図2
