A collection device includes a reception unit, a first inspection unit, and a first transmission request unit. The reception unit receives a data unit including operation data indicating an operation state of a plant and a guarantee value for guaranteeing authenticity of the operation data. The first inspection unit inspects the authenticity of the data unit by inspecting a quality of the data unit on the basis of the guarantee value and by inspecting the presence or absence of a loss of the data on the basis of a reception interval of the data unit. The first transmission request unit requests a transmission side of the data unit to retransmit the data unit when inspection results of the first inspection unit indicate no authenticity.
