The present invention relates to an oil distribution service system and method, and more particularly, to an oil distribution service system and method through a network and a flow rate measurement using an optical fiber sensor.

The optical fiber sensor can measure the flow rate in the storage tank of a gas station. When the optical fiber sensor is used as the flow rate sensor, it solves various problems in the management of the gas station, and measures through the accurate height measurement of the flow rate in the storage tank of the main station. It is used as a measuring device for the user to easily check and manage the management, leakage condition and temperature in the tank.

However, the existing flow measurement and management method has to be measured at any time by using a scale bar on the tank in order to determine the flow rate in the oil storage tank, measurement error according to visual inspection, safety management of the storage tank and oil. There was a problem with quality control. In particular, when measuring the level of the storage tank that is not currently standardized, the flow rate measurement is inevitable a considerable error in the process of converting to low flow rate, it is impossible to accurately inventory management. In addition, when the oil is shipped and received, the amount of oil capacity measurement errors per gas station, the leakage of oil due to oversupply, and the damage caused by leakage are less than 15 million won to 100 million won, which is based on 10,000 domestic gas stations The damage is up to 1 trillion won a year. Such massive national losses and environmental pollution caused by leakage can be prevented by using fiber optic sensors.

The optical fiber sensor flow measuring device solves the problems of the existing electromagnetic measuring device, and has the advantage of measuring the storage tank of medium to long distance.

In addition, oil measurement and integrated management enable simpler circuits to monitor the temperature, leakage, and water inflow in oil storage tanks through a single system or management computer, and can set high and low water level alarms and other alarm functions. .

Conventional level sensors used separate sensor devices to measure the level of different materials individually, but the fiber optic sensor miniaturized the sensor unit by simultaneously measuring the height of water and oil with only one optical fiber for measurement. The optical signal measured from the optical fiber sensor compares and analyzes the characteristics of the light detected by the transmitter / receiver including a light source for measurement and a light source positioned in a safe place outside the tank. The collected data can be delivered in the form desired by the user, and the data can be stored and managed in an independent stand-alone display (instrument) and personal computer and database.

In addition, the measuring device using the optical fiber sensor can be directly applied to measure the height of chemicals and liquids that are dangerous to handle in addition to petroleum.In this way, liquids or solid powders accurately measure heights in storage containers and reaction vessels in process management. It can be widely applied in the automotive industry. In addition, the measuring device using the optical fiber sensor can be applied to various industrial fields, such as inundation monitoring of special purpose sensors and underground facilities and various communication lines.

Among the optical fiber sensors, the sensor that measures the height of oil level has a level switch and a level meter method depending on the application. The measurement method includes a continuous measurement method and a point sensor method of measuring only a predetermined position.

In Korea, it is mainly produced by sensors of the generalized method by electric-mechanical method, and most expensive sensors have secured simple assembly technology by imports. At present, research and development of optical fiber sensor is in the beginning stage in Korea, and basic research is being conducted mainly at universities and government research institutes based on high precision and reliability of optical fiber sensor. In particular, the design and manufacturing technology of the sensor element, which is the core of the optical fiber sensor, has a high technical level difference from the developed countries and technical aspects.

Currently, the related technique for measuring the level of this surface is as follows.

   Kinds                How to measure       Remarks   Pressure Inject constant air pressure into the probe rod to measure the height of the air pressure High price, high error rate   Buoy Buoys on the surface of the oil level and height measurements using pulleys and counterweights connected to the outside of the tank Basic method, malfunction Fiber optic According to the change of the refractive index distribution of the optical fiber Through loss measurement Oily  Height measurement High precision, continuous measurement  Ultrasonic Measure the height by calculating the time when the reflected wave is received after launching the ultrasonic signal High error rate due to influence of external environment  Magnetic (Magnetic) Float the properties of the permanent magnet on the surface of the surface, and measure the height by attaching several Hall sensors to the probe rod to measure the strength of the magnet External electromagnetic influence Reed switch type Float of permanent magnet is floated on the surface of oil, and the height of the lead switch is measured by attaching the lead switch to dozens of probe rods. Many failures Large error range Capacitance method (conductivity method) Height measurement method using a differential transformer that floats the PLOAT between the 1st and 2nd coils and measures the height using the voltage induced in the 2nd coil. Short distance, complex electronic circuit configuration

The various measurement methods described above have advantages and disadvantages, and most of them have a problem of having a short range. Fiber optic sensors, on the other hand, can measure everything from fine distances to large storage tanks over long distances. The optical fiber sensor has many problems since it is used at a high price in the related parts, but recently, with the rapid development of information and communication, the price has been reduced and the sensor has high performance and reliability in a specific industrial field requiring more precise characteristics. Doing. The field of use of the sensor using the optical fiber is expanding, and the demand for the necessity is further increased due to the convenience of installation and operation and the low cost.

1 is a system schematic diagram of a conventional optical fiber flow rate measuring apparatus, and FIG. 2 shows a detailed configuration item of the optical fiber type flow measuring apparatus.

First, the optical fiber sensor unit 1 for measuring the height of the flow rate is located in a pipe tube made of a protective tube tube of about 20 to 30 mm in advance, and is introduced into the inside through a hole in the lower part of the sensor. The optical transceiver device 2 for detecting the optical signal is located in a safe place outside the flow tank, and serves as a photoelectric conversion device for converting the received optical signal into an electrical signal. The electrical signal thus changed is configured so that the user can easily check the various information of the oil storage tank by the application software of the independent display device 3 or the personal PC 4 in the state inside the tank.

3 is a diagram illustrating a cross-sectional view and a fabrication method of an optical fiber sensor by etching.

Fiber optic flow sensor technology measures flow rates based on the characteristics of two media with different refractive indices. Evanescent wave loss is characterized by the fact that some of the light coming from the medium with high refractive index is reflected and partially refracted at the interface of two mediums n1 and n2 with different refractive indices. However, above a certain angle of incidence (determined by the refractive index ratio of the two media), all the light is totally reflected rather than refracted by the other media. Although all light is reflected, an electromagnetic wave called an evanescent wave penetrates a very short distance of about one wavelength into a medium having a low refractive index. Therefore, the amount of light leaking out of the fiber changes according to the thickness of the cladding surrounding the core, which in turn affects the sensitivity of the optical fiber sensor.

The refractive index of a typical fiber is n1 <n2. At this time, there is an exponential decrease in the interface and a small loss to the outside of the optical fiber, which changes according to the thickness x of the cladding. β is the small modulus of the fiber, where the decrease is equal to I = I0e-βx, and I0 is the intensity of light incident on the optical fiber. Therefore, when the external refractive index n3 is larger than the refractive index of the core, the leakage of light is further increased. By using this measuring principle, the initial incident light and the current intensity ratio of the photodetector received and reflected by the change of the refractive index of the external material are reflected. The height (flow height) of the liquid can be known.

4 is a schematic diagram of an optical fiber sensor measuring apparatus.

As shown in FIG. 4, the output from the light source is first detected at the photodiode 1 PD1, and the photodiode PD2 measures the loss value reflected by the coating at the fiber end. . In this case, the optical fiber sensor measuring device may compare the loss value returned to the light source to determine the height (flow height) of the corresponding liquid.

Particularly, since gasoline has a refractive index of 1.57, it is larger than the core refractive index of a general optical fiber, and thus, when the thickness of the cladding is thin, the outflow of light increases and the loss value increases.

Gasoline has the highest absorption band region at 1.16 ~ 1.22 ㎛ and 1.36 ~ 1.42 ㎛. Therefore, when 1.3 μm of the corresponding light source is used, the loss in the optical fiber in the gasoline region is further increased, thereby improving the accuracy with respect to the gasoline height.

Compensation according to the temperature change requires compensation of the flow height circuit control according to the temperature change of the flow rate in the temperature sensor installed in the middle of the pipe.

When passing through the air, the light loss is relatively small, and when passing through the flow, the loss is relatively large. Using this principle, the height of the flow rate can be represented numerically and accurately according to the standardization characteristics with an analog or digital meter.
