That is, the data processing unit 231 collects the measured data from the second sensing unit 210A, and calculates the electric conductivity, the permittivity, the variation of the dielectric constant and the electric conductivity according to the temperature change, and the predetermined reference value of the genuine oil , And determines whether or not the measured oil is genuine by comparing the permittivity of the genuine oil or the variation of the electric conductivity or the dielectric constant according to the electric conductivity or the temperature change.

At this time, if it is determined that the measured oil is a non-genuine product, the data processing unit 231 generates non-property determination information and sends the sampling instruction information to the drive control unit 233 so that the drive control unit 233 opens the branching valve And a predetermined amount (preferably 1 to 2 liters) of the sample is transferred to the storage unit 300 as a part of the oil to be inspected.

The pumping means 330 installed between the first sensing means 210B and the second sensing means 210B and the storage portion 300 may be controlled by the drive control portion 233 The measured flow of the genuine product can be pumped to return directly to the inflow part 100 and can be recycled through the connection pipe.

The inspection apparatus 200 using the variation of the light transmittance described above and the variation of the electric conductivity, the dielectric constant, and the dielectric constant and the electric conductivity according to the temperature change communicates wired or wirelessly with the external server 400, (Not shown) connected to the data processing unit 231 and the drive control unit 233, and is connected to the external server 400. The server 400 is connected to the data processing unit 231 and the drive control unit 233, And a communication module 240 for communicating wired or wirelessly with the server of FIG.

Next, the storage unit 300 provides a reservoir for collecting a portion of the oil flowing into the inflow unit 100 and storing the sample as an additional inspection sample when the measured oil is not a genuine product, And a sample collecting container 310 connected to the sample collecting container 310.

It is preferable that the sample collecting container 310 is designed to be kept closed and secured so that it can be collected and managed only by the management institution 30 as a container for storing later the amount required for more accurate measurement in the management institution 30.

The storage unit 300 may further include a waste container 320 connected to the end of the discharge pipe 108 to measure the measurement oil discharged from the oil measurement container 211 after the measurement is completed, It is desirable to store one calibration solution and the residue of the existing measurement oil. As a result, the waste container can be collected periodically and disposal can be carried out through the separate treatment to prevent environmental pollution.

Next, the server 400 transmits information on whether or not the inspection apparatus 200 is authentic to the management organization 30 and transmits inspection instruction information from the management organization 30 to the inspection apparatus 200, 10, and is connected to the communication module 240 of the inspection apparatus 200 by wired / wireless communication, while the other side is connected to the management organization 30 by wire / wireless communication.

Therefore, information on whether the genuine article is generated from the inspection apparatus 200 is sent to the management organization 30 through the server 400 in real time or at the request of the management organization 30.

The server 400 further includes a memory unit (not shown) for storing data such as an installation gas station, a lubricator number, a measurement date and time, and determination information transmitted from the data processing unit 231, It is desirable to manage.

In addition, the management organization 30 sends the inspection instruction information to the server 400, and the inspection apparatus 200, after receiving the inspection instruction information from the server 400, It is possible to measure whether or not the product is authentic by introducing a part of the oil.

Hereinafter, a method of determining whether or not the oil that is sold at a gas station using genuine oil using a similar oil inspection and data collection / processing system for a gas station according to the present invention and managing the same will be described. For the sake of convenience of explanation, the same reference numerals and the same reference numerals are used in the description of the same parts with reference to FIG. 1 to FIG. 7 already mentioned.

At first, the genuine inspection using the system according to the present invention can be performed at every oiling, and optionally the inspection can be performed according to the inspection instruction information or the inspection time information arbitrarily generated by the management institution 30. Hereinafter, In the case where the inspection is performed according to the inspection instruction information or the inspection time information, the server 400 and the management organization 30 described above are applicable to those skilled in the art .

When oil is introduced into the vehicle through the gas filling unit 20 by the operation of the main body 10 of the vehicle, the oil sensing means 110 senses the flow of the oil passing through the inlet portion 100, And transmits it to the drive control unit 233. [0158]

The drive control section 233 opens the main inlet valve 102 and the sub inlet valve 103 with the discharge valve 109, the branch valve 104 and the calibration valve 107 closed, A part of the oil in the main oil distributed in the main tank is determined to be diesel or gasoline through the inlet pipe 101 and is transferred to the two oil measurement containers 211B and 211A.

First, when the incoming oil is light oil, when the measured oil is filled in the oil measurement container 211B of the first sensing means 210B, the sub-intake valve 103 is closed to make the oil measurement container 211B no longer flow into the oil measurement container 211B The drive control unit 233 applies electricity to the first sensing unit 210B and controls the heater 214B so that the measured flow rate of the introduced test oil is maintained at a predetermined temperature range of -15 ° C to 20 ° C, And irradiates light to the measurement air flowed through the light source part 212B and detects the intensity of the transmitted light passing through the measurement oil according to the change of the temperature value in real time in the transmitted light detection part 213B do.

In this state, the data processing unit 231 calculates the temperature conversion value measured from the first sensing unit 210B, the intensity data of the incident light of the light emitted from the light source unit 212B, And calculates the amount of change in light transmittance according to the temperature change by dividing the intensity of the transmitted light by the intensity of the incident light according to the temperature change based on the collected data.

Subsequently, the data processing section 231 compares the variation value of the light transmittance of the measured oil with the calculated temperature change and the preset reference value of the genuine oil to judge whether the measured oil is genuine or not.

At this time, if it is determined that the measured oil is similar oil and the illegal forgery is suspected, the data processing unit 231 generates the non-property determination information and transmits it to the drive control unit 233.

On the other hand, if the incoming oil is judged to be gasoline, if the measured oil is filled in the oil measurement container 211A of the second sensing means 210A, the sub inlet valve 103 is closed and the inside of the oil measurement container 211A The drive control unit 233 applies electricity to the second sensing means 210A while the second sensing means 210A applies electric power to the dielectric constant or electric conductivity of the measured oil in the oil measurement container 211A, To measure a change in dielectric constant or electric conductivity with temperature change.

The measured data is transmitted to the data processing unit 231, and is compared with a predetermined reference value of the genuine oil to determine whether the measured oil is genuine or not.

At this time, if it is determined that the measured oil is similar oil and the illegal forgery is suspected, the data processing unit 231 generates the non-property determination information and transmits it to the drive control unit 233.

The drive control unit 233 receiving the non-GMM determination information opens the branch valve 104 in a state in which the main inlet valve 102 is open and the sub inlet valve 103 and the calibration valve 107 are closed, To the sample collecting container 310 through the branch tube 104.

The sample oil of the predetermined amount (preferably 1 to 2 liters) thus transferred serves as a sample for further inspection, and the control organ 30 can collect it and perform more precise measurement.

The determination information of the measured oil thus determined is transmitted from the data processing unit 231 to the server 400 through the communication module 240. At this time, data such as the lube number, measurement date and time are transmitted together .

The server that receives the lube number, the measurement date and time, and the determination information (inspection information) transmits the luggage number, the measurement date and time, and the genuine determination information to the management agency together with the installation gas station information, (Not shown), and transmits the information when the management institution 30 requests it.

The drive control unit 233 closes the main inflow valve 102 and closes the branch valve 104 and the calibration valve 107 in order to prevent the main inflow valve 102 from being closed, (103) and the discharge valve (109) are opened to discharge the measurement oil filled in the oil measurement container (211) to the waste container (320).

The drive control section 233 controls the main flow valve 102 and the branch valve 104 to be closed and the sub inlet valve 103 and the discharge valve 109 is opened, the calibration valve 107 is opened and the calibration supply part 220 is operated to transfer the calibration solution into the oil measurement containers 211B, 211B. In this process, the calibration solution removes the existing measurement residual oil remaining in the inner wall of the inlet pipe 101 and the oil measurement containers 211B and 211B, and thus, an error occurs in determining whether the newly introduced measurement oil is genuine or not So as to initialize the inside of the inspection apparatus 200.
