The present invention relates to a remote monitoring device for a facility house heater, and more particularly, it is possible to accurately monitor the amount of duty-free oil supplied to the facility house heater and the actual use, and various obstacles and communication networks distributed in the facility house The present invention relates to a measuring device and a collecting device configured to overcome structural difficulties of the configuration, and a remote monitoring device for a facility house heater using a power line communication composed of a repeater and a server for transmitting and receiving measured and collected data.

The amount of horticultural production in China accounts for about one-third of the total agricultural production, and more than 50% of the total vegetable production is about 7% of the total vegetable production. Facility cultivation is an agricultural production system that can produce agricultural products throughout the year, regardless of changes in climate or weather conditions, by creating a space that is isolated from the outside with a covering material such as plastic or glass and creating a greenhouse environment suitable for crop growth. These facility houses require a control system configured to artificially control various factors such as light quantity, temperature and humidity required for crop growth, and an energy source such as oil to drive these devices. In particular, the facility house heaters for controlling the temperature inside the facility are driven as oils, which are duty free oil provided as part of the national support for agriculture. These duty-free oils are only half of the supply price excluding tax, and are likely to be released in large quantities, requiring systematic management.

Therefore, in order to support the efficient operation and improvement of the agricultural heating oil supply and demand system provided as duty-free oil, the operating time of the oil burner installed in the facility house heater is measured to estimate the fuel consumption from this, and the measured information is standard communication means. There was a need for a heating oil management system for agriculture that transmits through the air.

Korean Patent No. 167187 (1998.09.26: hereinafter referred to as "Publication 1") and Japanese Patent No. 167189 (1998.09.26: hereinafter referred to as "Technology for Measuring the Amount of Fuel Consumed Remotely" 2 ") discloses a technique for remotely reading a value accumulated in various meters such as an electric meter, a gas meter, a water meter, a hot water meter, and a calorimeter installed in each customer.
