The cultivation environment derivation unit 76 searches the measurement data and work record data of each sensor 61 to 66 associated with the plant P when it is determined from the growth state record shooting data that the plant P is appropriately grown. do. The measured data and work record data of each of the searched sensors 61 to 66 are stored with information as appropriate data added.

On the other hand, when the cultivation environment derivation unit 76 determines that the plant P is not properly cultivated (for example, with pests), the measurement data of each sensor 61 to 66 associated with the plant P and the measurement data Search work record data. The measured data and work record data of each of the searched sensors 61 to 66 are stored with information as inappropriate data added.

The cultivation environment derivation unit 76 includes measurement data and work record data of each sensor 61 to 66 to which information as appropriate data is added, and measurement data of each sensor 61 to 66 to which information as inappropriate data is added. And compare with the work record data to find different parts.

The cultivation environment derivation unit 76 recognizes that the pest has been attached to the plant P at the timing of the different parts found, and a voice indicating that fact (for example, "Because the temperature at x o'clock was higher than the set temperature, the plant" The pest was attached to the speaker 73. ”) Is output from the speaker 73.

Further, the cultivation environment derivation unit 76 derives the information of the different parts in the measurement data and the work record data of each sensor 61 to 66 to which the information as appropriate data is added as an appropriate work method, and derives the information to that effect. The following sound (for example, "when the temperature at x o'clock is the same as the set temperature, no pests were attached to the plant") is output from the speaker 73.

The cultivation environment derivation unit 76 is not limited to the above-mentioned ones, and may find out, for example, that irrigation is performed at x time as different parts. In this case, for example, a voice indicating that effect (for example, "Pests were attached to the plant because irrigation was performed at x time") was output from the speaker 73, and further, "when irrigation was not performed at x time" , No pests were attached to the plants. ") Is output from the speaker 73.

The present invention has been described above with respect to preferred embodiments thereof, but as can be easily understood by those skilled in the art, the present invention is not limited to such embodiments and deviates from the gist of the present invention. It can be changed as appropriate as long as it does not.
