Abstract
An inspection device includes an output unit, a storage unit, and an inspection unit. The output unit outputs a control signal for controlling a water supply valve to control supply and no supply of irrigation water from a water supply pipe in an open farm field, between an open state and a closed state. The storage unit stores water pressures of irrigation water as detected in a period from a state where the water supply valve becomes in the open state and irrigation water is supplied from the water supply pipe until an expected time elapses after the water supply valve becomes in the closed state and the water supply pipe is expected to be filled with irrigation water. The inspection unit calculates a time constant of water pressure based on the water pressures and inspects the water supply pipe based on the time constant.
