Abstract
Japanese rice plants began in the Jomon period, passed through the Konden Einen Shizai Law and other's law, and passed down to the present age. The primary industry and agriculture are declining as the secondary industry develops by the Fukoku Militia that started from 1800's. Agriculture was subject to rapid change that include a Clearing up to escape from the post-war food shortage, introduction of policy of reducing acreage when rice remains, adjustment of rice price by deregulated rice and liberalization of rice. In particular, agricultural proceeds were reduced to about one-third in 2015 compared to 1975 when converted to the initial salary of high school graduates. In 2018, the agricultural policy in Japan will reach one endpoint with the termination of policy of reducing acreage under cultivation. Declining agriculture means a decrease in water resources and a decline in future food self-sufficiency rate, and it does not deny a drop in national strength. In order to solve this problem, we tried developing indoor hydroponic equipment and remote monitoring grain dryer using IoT technology. In indoor water cultivation under the LED light source, rice grew until seedlings and heading. In the remote monitoring grain dryer, we monitor the emergency stop of the dryer via the Internet by measuring the exhaust temperature using Kinoma create and a temperature sensor, and the load of agricultural work can be reduced.
