Description

Technical Field [0001] The present invention relates to a measuring device for measuring the operating time of a heater, and a power line communication infrastructure management system for the same,

[0001] The present invention relates to a heating time measuring apparatus for a heating apparatus and a power line communication infrastructure management house management system having the same, and more particularly, An operation time measuring device, and a power line communication infrastructure cultivation house management system capable of efficiently managing a facility cultivation house by configuring various devices distributed in the facility cultivation house as a network.

Generally, plant cultivation is an agricultural production system that can produce agricultural products throughout the year regardless of changes in climate or weather conditions by creating houses isolated from the outside with a coating material such as plastic or glass and creating a greenhouse environment suitable for crop growth therein .

In such a facility, a control system is required to artificially control various factors such as light quantity, temperature and humidity required for crop growth, and an energy source such as oil for driving these devices is required. The heater to control is driven by oil, and the oil is used as a non-tax oil that is provided as part of national support for agriculture.

In order to support the efficient operation and system improvement of the agricultural heating oil supply and demand system provided by the duty free oil because the supply price excluding the tax is only about half of the actual market market price, There is a demand for an agricultural heating oil management system that measures the operation time of an oil burner mounted on a cultivating house heater, estimates the fuel consumption amount thereof, and transmits the measured information through standard communication means.

Conventionally, a measuring device for measuring a heating time of a heater detects a voltage signal or a current signal generated from a burner controller, compares the detected signal with a general operation signal set in advance, and when it is determined that the detected signal is a normal operation signal, The device is configured to measure and store the time of operation at that time as the running time of the agricultural heating device.

However, when the agricultural heating device is operated, the operation signal generated from the burner controller may be a heater of the same model manufactured by the same manufacturer, but there is a slight difference in voltage or current value from device to device. Accordingly, there is a problem that it is difficult to measure an accurate operation time of an agricultural heater by comparing a general operation signal set in advance with a conventional measuring apparatus and an operation signal generated from the burner controller.

As another example, in Korean Patent Laid-Open No. 10-2010-0007643, an apparatus for measuring the operating time of a heater is disclosed.

The heater operating time measuring apparatus includes an electric signal detecting sensor for detecting an electric signal flowing from the heater controller to the burner controller to operate the heater; Wherein the electric signal detected by the electric signal detecting sensor is set to an initial value of the normal operation signal of the heater and the initial value of the normal operation signal of the heater is compared with the electric signal detected by the electric signal detecting sensor And a meter for measuring the operation time of the heater when the set initial operation signal initial value and the detected electric signal are equal to each other.

On the other hand, a technology capable of measuring the amount of fuel consumed remotely has been proposed in Japanese Patent Application No. 10-0167187 (Patent Publication 1) and Patent Publication No. 10-0167189 (Patent Publication 2) A remote meter reading device capable of reading the values accumulated in various meters such as an electric meter, a gas meter, a water meter, a hot water meter, and a calorimeter, and a home control device of the remote meter reading system are respectively posted.

The home control device of the remote meter reading device and the remote meter reading system connects the central control station, the meter reading computer and the home control device via a single-phase power line. In the home control device, the pulse signal outputted from the plurality of meters is counted Then, the usage data is stored in its own storage area, and the usage amount of the meter is classified and stored according to the time of the user, and is displayed. When the usage data transmission request signal is input from the central control station through the single phase power line And to transmit the stored usage data.

This remote meter reading method is useful when the meter reading object such as a weighing facility inside the building is fixed and the distance of meter reading information through the electric power line is short. In most agricultural facilities, the meter reading object (especially agricultural heating radiator) And the meter reading object is transferred or discarded without notifying or notifying to the relevant institution in many cases. Therefore, when the above-described developed technology is applied, the meter system, the measuring apparatus, and the home control apparatus use the fixed address system, It is difficult to systematically manage the objects to be inspected.

In addition, a conventional remote meter reading system requires a large number of transducers, repeaters, and fixed transponders in order to transmit data from a measuring device distributed over a wide area of several kilometers or more to a final data acquisition server computer. Especially, If the area to be surveyed increases, the cost for remote transmission increases drastically and it is not possible to apply it realistically. In addition, there are various fixed obstacles such as pipe structure, vertical and horizontal curtains and driving wires, Since the variable obstacles vary depending on the growth, it is very complicated and costly to construct a network of sensors and controllers through various obstacles in the facility house.
