However, according to the preceding patent, various types of sensors must be used according to the heat source, and in particular, the current detector (CT) method needs to separate and install one strand from two strands of wires, thereby increasing the replacement time and cost, so that the farm or government There is a problem that acts as an economic burden.

An object of the present invention for improving the conventional problems as described above, using a relatively simple configuration, while increasing the accuracy of the measurement with ease of installation and to reduce the economic burden for widespread farmhouse use amount of the farm heat source To provide a measuring device.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention discloses a device for measuring the amount of use of the individual heat source (10). The heat source 10 generally means, but is not limited to, agricultural radiators, boilers, dryers. Usage is finally calculated as a cumulative time, where "cumulative time" means the accumulated operating time of the heat source (10). In particular, accurate measurement of the amount of heat source 10 is essential for farmers to which the government is exempted from tax exemption, and it is necessary to solve the economic burden due to the increase of replacement time and cost as well as securing fairness through accurate measurement.

According to the present invention, the respective detection sensors 31, 33, 35 are installed to detect operating states of the fan motor 11, the igniter 13, and the oil pump 15 of the heat source 10. Heat source 10, such as agricultural radiators, boilers, dryers mainly use the oil burner as a heat source, the oil burner includes the igniter 13 and the oil pump 15 as a main component. In addition, a fan motor 11 is provided in the heat source 10 to remove residual gas before operation. In such a configuration, the operation of the fan motor 11, the igniter 13, and the oil pump 15 is an important factor for determining whether the heat source 10 is operated, and thus the fan motor 11, the igniter 13, Each detection sensor 31, 33, 35 is provided to detect whether the oil pump 15 is operating.

At this time, the detection sensors 31, 33, 35 are preferably in contact with each of the conductors leading to the fan motor 11, the igniter 13, the oil pump 15 to detect the operating state. In general, the non-contact current detector used is a CT (current transformer) method, so it is necessary to penetrate only one strand of the conductor (wire), which is inconvenient to separate the conductors in which the two strands are attached together. This causes a disadvantage that the work time is increased due to the work on the heat source 10 pre-installed in the farm or the replacement of the detection sensors 31, 33, 35. The non-contact detection sensors 31, 33, 35 according to the present invention adopt a method of attaching non-contact state on two wires of the fan motor 11, the igniter 13, and the oil pump 15, respectively.

On the other hand, the detection sensors 31, 33, 35 is characterized in that it detects the voltage of the conductive wire by using a structure wound around the coil core. The non-contact voltage detection sensor 31, 33, 35 is a structure in which the coil is wound around the ferrite drum core in multiple rotations, and the fine AC voltage signal induced in the coil is amplified by the amplification unit 36 to DC. After the conversion is used as an input signal of the controller 40 to be described later.

In addition, according to the present invention, the controller 40 detects the operating sequence of the fan motor 11, the igniter 13, and the oil pump 15, and calculates the cumulative time during which it is determined to be in normal operation in comparison with the set sequence. And simultaneously save. The operating sequence of the fan motor 11, the igniter 13, and the oil pump 15 is important for the stable operation of the heat source 10. If it is out of the set sequence, it is abnormal operation state and should be excluded from usage (cumulative time) to ensure the accuracy and fairness of measurement.

At this time, the controller 40 is a microcomputer 41 for controlling the operation of the heat source 10, a storage unit 42 for storing the set operation sequence and the accumulated operating time, the time recording unit 43 for calculating the accumulated time And a display unit 44 for displaying the accumulated time, a communication unit 45 for remotely transmitting the stored data, and an alarm unit 46 for alerting the set abnormal state. The microcomputer 41 is a microprocessor circuit having an input / output interface and a memory, which controls the cumulative time measurement of the present invention together with the overall control of the heat source 10, and the storage unit 42 is a memory accessible to the microcomputer 41. The accumulated time data is stored together with the criterion of normal operation, the time recorder 43 generates a date and time as a timer circuit, and the display unit 44 measures the operation state and the accumulated time outside of the heat source 10. The state outputs, the communication unit 45 transmits data as a circuit based on RS232C or the like, and the alarm unit 46 outputs abnormal operation as a speaker or a lamp.

In FIG. 2, reference numerals 21, 23, and 25 denote progressively associated with on-off operation of the fan motor 11, the igniter 13, and the oil pump 15.

An example of a specific operation will be described with reference to FIG. 3.

First, the microcomputer 41 goes through a step of detecting whether the fan motor 11, the igniter 13, and the oil pump 15 are operated in order. When operation is input from the input unit 38 of the controller 40, the fan motor 11 operates first to blow out residual gas, and after 1 second, the igniter 13 operates to generate a high-pressure flame, and after 2 seconds, the oil pump 15 ) Is fired by spraying fine particles of oil. When the on state of the fan motor 11 is detected in step S12, the on state of the igniter 13 is detected in step S14, and the on state of the oil pump 15 is detected in step S16. If NO in step S14, there is an abnormality in ventilation. If NO in step S16, it is determined that there is an abnormality in ignition. T1 and T2 are values set differently according to the heat source 10.

Next, the microcomputer 41 goes through a step of detecting whether the igniter 13 is turned off within a set time. Once the ignition succeeds, the igniter 13 is stopped after T3 seconds since no high pressure flame is needed anymore. In step S18, the fan motor 11 and the oil pump 15 detect whether the igniter 13 is in the off state while being on, and if NO, the ignition has failed, and if YES, the process proceeds to the next step S22. T3 is a value set differently according to the heat source 10.

Finally, the microcomputer 41 accumulates the operation time when it is determined to be in normal operation, and outputs an alarm when it is determined that it is abnormal in operation. In step S22, it is finally determined whether the normal operation is performed, and the "normal operation" may include other conditions (for example, fuel shortage, etc.) set separately according to the heat source 10 in addition to passing all the above-described steps. have. If YES in step S22, the operation time is accumulated and stored in step S24. If NO, an alarm is output in step S32, and the accumulation of the operation time is stopped through step S28.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
