DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a lubrication operation inspection apparatus and an analysis method thereof according to the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a view showing an oil market monitoring system according to an embodiment of the present invention. The oil market monitoring system includes a lubricator 100, a lubricator operation inspection device 200, and a fuel information management system. The information management system includes a relay apparatus server 300 and a management server 400.

First, the lubricator 100 is a device for injecting the oil from the oil storage tank into the vehicle or a desired container quickly and efficiently by a necessary amount, and includes a dedicated oil meter. Lubricators can be used for a variety of purposes including industrial classification, classification by display method, classification by metric value setting method, classification by driving force, classification by use, classification by structure, classification by pumping method, And use. In addition, the structure of the lubricator is divided into a ground stationary suction type lubricator fixed on the surface of the gasoline station, a ground fixed type supercharger lubricator, a ceiling lubricator and a mobile grooved lube lubricator.

The main functions of the lubricator are as follows. The distribution function is the suction and discharge function by the pumping system, the cleaning function is the filtration and air separation function by the cleaning system, and the weighing function is the flow measurement system by the flow metering system (Flow Metering System) And the integration function performs flow display and integration by the counting system.

The operation principle of the lubricator is such that when the lubrication is started, the nozzle is turned on, and at the same time the solenoid valve and the motor are driven, the pump rotates, the oil is sucked from the underground tank to discharge the nozzle, The foreign matter and the air of the introduced oil are purified by the filter and the air separator and sent to the flow meter. There is a strainer in the suction part of the pump to prevent the oil tank and the dust in the pipe from flowing into the pump, and an inlet check valve is provided so that the oil in the pump does not flow backward. The oil that comes into the pump is again dirt and water removed by the filter. Light oil containing air enters the air separation chamber through the air valve at the top of the filter chamber and is separated into air and oil. The air valve functions to prevent the air containing air from entering the air separation chamber. The separated air is discharged to the atmosphere from the upper part of the air separation chamber. When the air separated from the air is left in the air separation chamber and becomes a constant oil surface, the float buoyancy opens the valve and returns to the suction side of the pump. The discharge side of the casing is provided with a relief valve for circulating the oil in the pump in order to prevent the internal pressure from rising when the nozzle is closed and the oil supply is made at a low speed. Also, it can be adjusted by a spring so that the discharge amount can be increased or decreased by increasing or decreasing the discharge pressure. The check valve on the discharge side is opened by fluid pressure during lubrication but is automatically closed to prevent backflow of the metered oil in the hose and flowmeter when the nozzle is closed and maintains the hydraulic pressure of the hose and flowmeter during operation stop, Prevents rotation of the flowmeter due to hose expansion during lubrication. The outlet check valve is equipped with a pressure relief valve, which is a compact valve that opens when the pressure rises above a certain pressure to prevent pressure rise in the piping system when the oil filled after the flow meter due to changes in the outside temperature. The oil introduced into the flowmeter flows into the first flow chamber along the openings of the rotary valve and pushes the piston in. This causes the piston of the opposite flow chamber connected to the york to push the already filled oil out of the flow meter. The linear motion of the piston is converted into a rotational motion by the camshaft, and is connected to the pulse generator connected to the outside of the flowmeter to rotate it. For example, the pulse generator generates 50 pulses per rotation of the A-phase and the B-phase, respectively, and the pulse is input to the main board of the lubricator to perform the calculation. The main board converts the number of input pulses into a unit of volume and displays it by multiplying the input unit price by the amount.

In the present invention, the flow meter capable of detecting the manipulation of the lubricator may include various types, and the output thereof may be given in the form of a pulse signal. Even if the pulse waveform is encoded by any other signal, Since it is only necessary to extract the signal, there is no problem in detecting the manipulation of the lubricator.

Particularly, the flow meter of the lubricator plays a central role in the lubricator, and since it measures the amount in the flow meter, it becomes the basis of the lubrication accuracy of the lubricator. The oil discharged from the pump flows into the cylinder through the cutting portion of the rotary valve, and the flow meter operates by pushing the piston. At the same time, the other piston in the opposite direction of the piston is pushed outward, and the oil present inside is discharged through the rotary valve and the flow meter to the outlet. At this time, the reciprocating movement of the piston causes the yoke connected to the roller to move, the cam is rotated, the rotated cam moves the next piston, and the four pistons sequentially move and reciprocate. The reciprocating motion of the four pistons converts the cam and the shaft into rotational motion, while the rotational motion of the shaft rotates the rotary valve while the cut-off portion of the rotary valve is sequentially opened to the four cylinders. The rotary motion of the shaft is transferred to the counter by the pulse generator connected to the axis, and the weighing value is displayed. At this time, the gasoline information of the gasifier is collected in real time and transmitted to the relay device server through the wired or wireless network.

Next, the main unit operation inspection apparatus 200 is implemented as a small module and is easily connected to existing facilities of the main unit without change. The main unit operation detection unit 200 detects in real time whether or not the flow sensor of the main unit is operated, , And collects gasoline information such as gasoline amount and gasoline amount in real time and transmits it to a relay device server through a wired or wireless network to manage it.

Next, the relay device server 300 transmits the oiling operation detection result and the oiling information analyzed for each lubricant input from the lubricator or the oiler operation inspection device to the real-time monitoring device through the relay device server installed in each gas station using the network or text service To the management server. At this time, it is not necessary to pass through the relay server, but it can be integrated and transmitted by the oil information management system.

Next, the management server 400 informs the related organizations including the petroleum management agency, the government agency, the oil refiner, and the credit card company of the flow rate inspection result data inputted from the relay server server to perform a crime such as manipulation of the oil pump, fake oil, fake sales, And it is possible to manage the oil market more systematically, and it is also possible to inform the website or the application in real time so that the consumers can refer to the oil information by referring to the oil information. Here, the function of the management server and the function of the relay device server may be implemented by integrating any one of the devices.

FIG. 2 is a connection diagram showing a gasifier, a gasifier operation inspection apparatus, and a gasoline information management system according to an embodiment of the present invention. The gasifier 100, the gasifier operation inspection apparatus 200, the relay server 300, and the management server 400 ).

2, the main unit 100 includes a flow sensor 110, a main board 120, and a display unit 130. The main unit 100 includes a preset, a hose, an electronic control unit, a flow meter, And the like, and there is no specific configuration limitation.

In the flow sensor 110, a flow sensor (not shown) having a plurality of holes may be mounted in a nozzle connected to the end of the lubricator. At this time, when a flow of oil flows along the flow path in the nozzle, one hole of the plurality of holes of the flow sensor is selected to transmit the wavelength of light including infrared rays, ultraviolet rays, and visible rays to the hole, Is output. Pulse signals are logically 0 and 1 using a pulse waveform of two voltage levels of 0 and 1 in a digital system, where a pulse is a waveform that changes from a stable value to a stable value over a very short period of time , The pulse signal is a waveform signal that returns to its original state after the amplitude has been maintained for a certain period due to the amplitude from the steady state. In other words, the duty cycle is converted into a pulse signal having a flow rate and output.

The optical pulse signal of the flow rate sensor is converted into an electric pulse signal by an encoder and output to the main board 120 or the gas pump operation inspection device 200 through the electric wire 111 as shown in FIG. For reference, a pulse signal can be simply transmitted as an electrical signal, but it can also be encoded and transmitted in a code having a specific format.

In the present invention, when the encoder of the flow rate sensor is operated, a signal different from the pulse signal normally generated by the flow rate sensor is generated. Therefore, the operation of the pulse operation inspection apparatus 200 may be checked by checking operation of the pulse signal itself, The signal can be compared and analyzed to detect whether the encoder is operated or not. Also, a flow rate checker (not shown) may be brought into contact with the tab 112 shown in FIG. 2 to check the operation signal of the flow rate sensor to detect whether the encoder is operated or not. At this time, a flow rate inspection may be performed using a connector or a needle instead of the tab.

For reference, the flow rate is one of the most measured quantities measured at the industrial site along with the pressure, temperature, and level. The flow measurement is the most difficult to measure. The measurement method is also used for measuring purposes (eg, Various types of flowmeters can be used depending on the properties of the liquid, gas, vapor, and fluid (eg, density, viscosity, specific heat, temperature, pressure, electrical conductivity, etc.). In the present invention, a flow meter including a flow rate monitor, a flow rate switch, and a differential pressure meter may be used as a capacity meter for measuring the amount of liquid flowing in a unit time, that is, volume or mass.

The main board 120 is a printed circuit board manufactured by using main components for operating the lubrication apparatus. The main board 120 sets the execution environment of the lubrication apparatus, maintains the information, and stably drives the lubrication apparatus. It facilitates data I / O exchange with other connected devices. In the present invention, the main board 120 receives the pulse signal of the flow sensor 110 and calculates the amount of the pulse signal input by the pre-stored amount per liter. At this time, the main board 120 stores gasoline information including gasoline type, gasoline, gasoline amount, and gasoline amount, and can store information that the user wants to input. The information on the calculated amount of gasoline, the type of gasoline, the gasoline, and the amount of gasoline is output to the display unit 130 and the data signal of the main board 120, which is analyzed and compared with the pulse signal of the input flow rate sensor 110, The main board 120 can be checked whether or not the software of the main board 120 is operated.

The display unit 130 displays gasoline information including the gasoline type, gasoline, gasoline amount, and gasoline amount input from the main board 120 in the form of numbers and characters through a liquid crystal display device such as an LCD or an LED.

The operation of the gasifier 100 including the flow sensor 110, the main board 120 and the display unit 130 can be monitored in real time through the gasifier operation inspection apparatus 200.

2, the main control unit 200 receives the pulse signal of the flow sensor 110 of the main pump 100, the main board 120 data signal, and the data signal of the relay apparatus server 300 Real-time monitoring of flow manipulation is performed.

First, in real-time monitoring of the operation of the pulse signal of the flow sensor 110 of the lubricator 100, a pulse signal different from the normal pulse signal of the flow sensor 110 is generated when the encoder is operated, And the pulse signal of the normal flow sensor 110 stored in the memory 200 to detect whether the operation is performed in real time. At this time, if the oil pump operation inspection device detects whether or not the flow sensor is operated, the inspection contents are transmitted to the relay device server through an operation alarm alarm program (not shown).

The real time monitoring of the operation of the main unit 120 of the main unit 100 is performed by comparing the data received from the encoder of the flow sensor 110, that is, the pulse signal, with the data output to the display unit 130, I do it. When the software of the main board 120 is operated, the flow rate and the amount of gas per liter are calculated based on the normal data received from the encoder of the flow sensor 110, and compared with the data output from the main board 120, It is possible to detect whether or not the operation is performed. At this time, when the main-pump-operation-inspection-testing apparatus 200 detects whether or not the software of the main board 120 is operated, the main control unit 200 transmits the inspection content to the relay apparatus server 300 through an operation alarm alarm program (not shown).

In addition, the pump operation inspection apparatus 200 receives the standard speed signal of the same nozzle, that is, the nozzle standard, and the average speed of the other nozzles provided from the relay device server 300, and receives the pulse signal of the flow sensor 110 or the pulse signal of the main board 120, and the flow velocity of the nozzle is analyzed to detect whether the flow rate is manipulated or not, and at this time, the inspection content is transmitted to the relay server 300 again.

Next, the relay device server 300 receives the inspection contents analyzed by the oiler operation inspection device 200 and transmits the inspection contents to the related organization 500 including the petroleum management agency, the National Tax Service, the police agency, the oil refiner, and the card company through the network. In addition, inspection contents and fueling information of the relay apparatus server 300 are registered in the Internet, so that the consumers can confirm the fueling information in real time.

For reference, in each of the above embodiments, each constituent unit constituting the manipulation-unit inspection apparatus is described only for convenience of explanation. Actually, any constituent unit may process all the operations, or may be subdivided into more various constituent units Or may be configured to process the constituent means in combination. It is also possible to provide a manipulator inspection device based on the SNS server.

As described above, according to the present invention, there is provided an apparatus for inspecting a manipulator for manipulating a manipulator of a manipulator and a method for analyzing the manipulator, comprising: And transmits the processed signals to the relay device server. In the relay device server, the collected and analyzed data is transmitted to the petroleum management office, the National Tax Service , A police agency, a refiner, a credit card company, etc., or a web page that consumers can browse.

FIG. 3 is a block diagram illustrating the configuration of a gas pump operation inspection apparatus according to an embodiment of the present invention.

First, a pulse signal analyzer (not shown) receives a pulse signal 113 of a flow sensor from a flow meter operation inspection apparatus and analyzes a flow pulse signal in the flow pulse signal analyzer 210. At this time, although the flow pulse analysis is not shown in the drawing, it is possible to comparatively analyze the waveform of the flow pulse, the periodic fluctuation analysis of the flow pulse, and the flow pulse cycle in the normal flow state. The standard speed, the average speed, the standard speed for the other nozzles, and the average speed for the other nozzles stored in the relay server 400 are input to the flow rate analyzing unit, And the derived data is input to the flow pulse signal analyzer 210 to compare and analyze the flow pulse period in the normal inflow state. Further, the flow rate comparing unit 220 compares the data derived from the flow pulse signal analyzing unit with the flow rate. At this time, the flow rate comparing unit 220 compares the data of the display information extracting unit 132 and the data of the flow pulse signal analyzing unit, which are obtained by extracting the flow rate and gasoline price based on the output signal of the display unit. Also, the main-flow-information reporting unit 230 collects the main-pump operation signal data (i.e., error information) sensed by the flow pulse signal analyzer 210 and the flow-rate comparison analysis data together and transmits data to the relay- do.

In other words, the pulse signal of the lubricator flow sensor; Standard information including the standard speed for the same nozzle, the average speed for the same nozzle, the average speed for other nozzles of the same type, and the number of pulses per rotation for the nozzle, or information including combinations thereof; A signal output to the display unit of the lubricator; Or an input unit for receiving at least one of these combinations. Here, the input interface can receive signals and information through an input meter reading unit including tabs, connectors, and needles. In the case of the needles, the wires may damage the cover. Therefore, it is desirable to provide separate tabs or connectors so that they can be connected to each other. Also, it is possible to provide a simple wireless communication module or a dongle so as to provide convenience of the interface.

The standard speed and the average speed of the same nozzle and the other nozzles can be used to grasp the rotation speed of the disk of the flow sensor and the cycle of each pulse, and if the flow rate per cycle is known, the flow rate can be calculated.

The analysis unit includes an analysis unit for analyzing input signals or information, such as a flow pulse analysis unit, a flow rate comparison analysis unit, and a flow rate analysis unit. And a flow rate analyzing unit for analyzing the flow rate and calculating a standard value for a standard pulse cycle per nozzle, wherein the gas-pump operation monitoring apparatus displays a display for extracting information including a flow rate, a price, or a combination thereof from the input display information And an information extracting unit.

The analysis unit may further include a flow rate information calculation unit for calculating flow rate information from the pulse signal of the flow rate sensor and the average speed of the nozzle. That is, the standard speed and the average speed of the same nozzle and the other nozzles can be used to determine the rotation speed of the disk of the flow sensor and the cycle of each pulse, and if the flow rate per cycle is known, the flow rate can be calculated.

The determination unit may determine whether the pulse signal is manipulated based on the analysis result. The determination unit may determine whether the pulse signal is manipulated by comparing the calculated flow rate information with the extracted flow rate information, An analysis including a duty cycle error of a signal, a pulse period variation, a pulse amplitude variation, or a combination thereof is performed, and then the determination unit compares the analyzed result with a corresponding reference value and outputs the result through the output unit And also determines whether the lubricator is operated by comparing the absolute value of the difference between the average value of the flow pulse periods in the normal main flow state calculated by the analysis unit and the standard value with the tolerance range in the determination unit. And it is also possible to output the result of the flow rate comparison through the output unit.

In addition, the pulse signal analysis may be performed by using a pulse signal having a duty cycle of a pulse signal, pulse period variation, pulse amplitude, or pulse width of a pulse signal between individual pulse signals, between adjacent individual pulse signals, between pulse signals at repeated positions along the rotation of the disk holes of the flow sensor, Volatility, or a combination thereof.

The output unit may output the result to a self display of the device for operating the ladle operation unit, or may include a user terminal, a fuel information management system including a relay device server and a management server, , A card company or an affiliated organization including the petroleum management agency, or a combination thereof, and is also capable of outputting information including the flow rate, flow rate, or a combination thereof output from the analysis section, It is possible to output the gasoline information including the outputted error information.

As shown in FIG. 3, the lubrication operation inspection apparatus can perform the above-described processes and detect whether the lubrication apparatus is operated in real time.

FIG. 4 shows various pulse signals of a flow sensor of a lubricator as an example of a pulse signal of a flow sensor according to an embodiment of the present invention.

Fig. 4 (a) shows an example of a pulse shape in a normal inflow state.

First, a pulse refers to a waveform that changes from a stable value to another stable value within a very short period of time. At this time, the waveform signal that returns to the original state after the amplitude is sustained for a certain period due to the amplitude from the steady state is referred to as a pulse signal. When the pulse signal is a positive logic, a value that varies between 0 and 1 means that the amount of a physically high value is a logic level "1 ", and when the pulse is a negative logic, Quot; 0 "to the logic level " 0 ". That is, as shown in FIG. 4A, "1" indicates a high or on state, and "0" indicates a low or off state. Lt; / RTI >

The pump operation inspection device for checking whether or not the flow sensor is operated will be described in more detail in the following three detailed steps.

First, the flow sensor responds to the flow of the flow, and a plurality of uniformly spaced holes are uniformly formed in the rotating disk, so that light is transmitted before and after the disk to sense light on the opposite side. Accordingly, when one hole of the plurality of holes is selected and an electric current flows through the hole, it becomes an on signal. If the hole is not transparent, it becomes an off signal, so that the duty cycle is constant, The cycle can be changed. However, the duty cycle must remain constant throughout the entire sensing period, and the variation of this duty cycle should be within an acceptable range. It is possible to judge whether there is an error by looking at the degree of matching of the duty cycle, the pulse period variation, or the pulse amplitude fluctuation for the pulse corresponding to the repetition period according to the rotation of the disk.

Here, the duty cycle refers to a pattern of a certain repetitive load during a given period, and refers to a ratio of the running time to the cycle period. That is, the duty cycle means a ratio of an on state to a period of one period, that is, a sum of an on state and an off state when the transmission signal is turned on and off in the pulse transmission waveform, The pulse width and the ratio of one cycle T as shown in Fig. 4 (a). At this time, the ratio of the on state to the off state is referred to as a duty ratio and has a value between 0 and 1.

As shown in FIG. 4 (a), the duty ratio in the on state is t1 / T, and the duty ratio in the off state is t2 / T.

The calculation of the duty cycle is as shown in [Equation 1].

[Equation 1]

Duty cycle

At this time

(A) of FIG. 4A, that is, a pulse width having a value of 1, and T denotes a period of one cycle, that is, an on state and an off state Represents the sum of time.

For example, if the widths of 1 and 0 are equal, the duty cycle is 0.5 or 50%. In this case, the frequency is the number of oscillations per second, which is equal to the number of oscillations per second. Also, as shown in Fig. 4A, one pulse corresponds to a flow of a small amount of flow (for example, 20 ml) flowing in one of the holes of the flow sensor of the lubricator, so that the duty cycle or the duty ratio is Not only is it perfectly constant in steady state at steady speed, but it should also be almost unchanged at low speed or shift. By using this characteristic, it is possible to judge whether or not the pulse signal is manipulated by checking whether the change of the duty cycle of the flow pulse during main flow is within a certain error range.

Next, the pattern of the pulse signal period for the flow rate of the flow sensor is analyzed as follows. It is checked whether the same pattern is maintained in the cycle of the pulse with respect to the flow rate in the entire lubrication cycle including the acceleration phase at the start of fueling, the normal phase at the constant speed, and the deceleration phase at the end of the fueling. If a pulse cycle that deviates from the flow pattern of such a flow is repeatedly generated, it can be judged by an artificial operation. In the acceleration and deceleration stages, it is possible to analyze the consistency of the pulse signal to check whether or not it is operated. In this case, however, it is possible to inspect the operation of the lubricator more precisely by further inspecting the whole amount of gasoline.

Next, the standard value of the flow rate in steady state for each type of lubricator is received from the server and compared with the pulse period of the flow sensor to check whether it deviates from the mechanical error range. At this time, the standard value and the error range are determined based on the lubricator specification of the same model and the flow rate of the other lubricators of the same model stored in the server. Failure to receive such data shall be based on the average stored in the previous storm event. By doing so, the attachment of the flow sensor operating device of the lubricator can be detected until the flow sensor is installed from the beginning or mounted on the way.

As described above, in the signal processing using the duty cycle, it is checked whether the average value of the duty cycle of the pulse signal is within a predetermined range or the duty cycle or cycle of one pulse signal is set to be the same with the number of pulse signals per one rotation of the flow sensor And if at least one of them is not satisfied with the condition, it can be judged by the operation of the flow rate sensor. In addition, only two lines, ground line and output signal line, are connected in parallel among the output signals, and signal level is converted if necessary. Then, the signal level is converted into standard The flow rate and amount information transmitted to the signal line is extracted by using the serial communication protocol and compared with the flow rate and the amount of money information converted from the information input from the flow sensor and the relay server to judge whether or not the main controller of the lubricator is operated can do.

FIGS. 4 (b), 4 (c) and 4 (d) show examples of pulse shapes in the operated state. 4 (b), 4 (c) and 4 (d) which are out of the error range of the pulse signal in the normal main state in FIG. 4 (a) are compared as follows.

It is a matter of course that the pulse signal exemplified here is viewed from the viewpoint of the digital signal, and distortion of the signal can be detected more variously by the distortion of the signal etc. in the analog signal. That is, the analog pulse signal may be further finely sampled to calculate an average value per rotation of the flow sensor to compare between consecutive rotations. The average value may be compared with a reference value to judge whether or not the lubricator is operated.

Fig. 4 (b) shows a pulse shape of the operated main state. When the error value of the pulse width in the normal main state shown in Fig. 4 (a) is too small or too large, , Which indicates that the flow sensor has been manipulated.

4 (c) shows a pulse shape of another operated main state. In contrast to the pulse period fluctuation of the normal main driving state in FIG. 4 (a), the pulse period of the normal main driving state is shorter or longer It is possible to indicate the operated pulse period of the main flow state as described above, and thus it can be known that the flow rate sensor has been operated.

Fig. 4 (d) shows the pulse shape of another operated main state. When the error value of the pulse amplitude in the normal main state shown in Fig. 4 (a) is too small or too large, It is possible to indicate the pulse amplitude of the flow state, which indicates that the flow sensor has been manipulated.

In this way, the operation of the flow sensor can be sensed by comparing and analyzing the information including the pulse width, period, and amplitude of the duty cycle indicating the steady main state of the duty cycle. At this time, The accuracy of the oil pump operation inspection apparatus varies depending on the sampling frequency, that is, the sampling frequency.

FIG. 5 is a flowchart showing a configuration of a gas pump operation inspection method according to an embodiment of the present invention, and the signal processing steps in the gas pump operation inspection apparatus will be described in detail.

First, the operation of the lubricator operation inspection apparatus compares the operation ratio of the flow rate sensor pulse signal inputted from the flow rate sensor of the lubricator, that is, the duty cycle and the flow rate pulse waveform, with the normal flow rate pulse signal stored in advance in the lubricant operation inspection apparatus (S01). At this time, when the operation rate of the flow sensor pulse signal is within a predetermined error range of the normal operation rate of the normal flow rate pulse signal stored in the operation device of the lubricator operation, the signal is regarded as a normal pulse signal and a signal is output to the flow rate pulse volatility analysis step. , It is regarded as an abnormal pulse signal and a signal is output to the error reporting step (S08) to report the operation of the flow rate. In addition, the pulse signal within the normal operating ratio range is analyzed to analyze the fluctuation of the flow rate pulse period (S02). The periodicity fluctuation is a numerical value of how often the pulse period varies and how much it changes. For example, the pulse period sampling period is checked every sampling period to compare with the adjacent pulse period, It is possible to check the amount of change between adjacent rotations and to digitize it.

At this time, when the value of the flow pulse variation value is larger than the error range of the predetermined reference value, it is determined by the operation of the flow rate and the signal is output to the error reporting step (S08). If the flow pulse variation value has a value of the reference value or an error range of the reference value And outputs a signal to the normal pulse period analysis step. In the relay server, the flow velocity of each nozzle is analyzed through the standard speed of the same nozzle of the lubricator, that is, the standard and the average velocity data of the other nozzles, and the cycle of the standard pulse per nozzle is derived. The thus derived period of the standard pulse per nozzle is inputted to the normal pulse period analysis (S03), and the flow pulse period in the normal main flow state is compared and analyzed. At this time, if the absolute value obtained by subtracting the standard value of the standard pulse cycle per nozzle input from the relay device server from the average value of the pulse cycle in the normal running state is larger than the error value of the standard value, And outputs a flow rate pulse signal to the flow rate comparative analysis step when it has a value within the error range. In addition, the flow comparison analysis (S05) is based on the flow pulse period analysis signal of the normal main flow state and the result of extracting the flow amount and the flow amount from the signal outputted from the display portion, that is, the signal of the flow amount display portion (S06) . At this time, if the difference between the flow rate of the pulse signal in the normal main flow state, the flow rate of the flow rate display portion, and the flow rate extracted by the gas flow amount is out of the error range of the predetermined flow rate, And outputs a signal to the gasoline information reporting step when it is within the error range. Also, the fueling information report (S07) integrates the signals of various error reports (S08) generated or extracted in the above steps and the basic fueling information including the nozzle specific ID, the flow rate per nozzle, the flow rate per amount of oil, Generates a main signal information reporting signal, and transmits it to the relay apparatus server S09 using the public network including the network or the Internet. Herein, the fueling information may be additionally added as needed, and it will be obvious that it is within the scope of the present invention.

For each of the signal processing steps including the steps S01, S02, and S03, an arbitrary step may be selected and the sequence may be changed.

6 is a flowchart showing another configuration of the gas pump operation inspection method of FIG.

6, the pulse signal of the flow sensor is used for each analysis step, that is, the flow pulse waveform analysis step, the flow pulse pulse periodicity analysis step, and the flow pulse period Input in the analysis step. It is possible to analyze whether or not the user operates the pump by performing at least one step without performing the above three steps.

Such analysis of the operation of the lubricator can detect real time operation of the flow sensor of the lubricator in the lubricator operation inspection device attached to the lubricator and can detect the operation of the main board of the lubricator in real time and can detect the lubricant type, And oil supply information including real-time fuel oil information can be transmitted to the related organizations including the petroleum management agency, the National Tax Service, refineries and credit card companies through the relay device server, and it is possible to easily install the oil pump operation inspection device There is an advantage. In this way, it is possible to detect gas stations that are under-metered by manipulating the lube oil in real time and be immediately notified to related organizations and consumers through the network, as well as consumers can inquire the amount information of the surrounding gas stations through the network anytime and anywhere. . In addition, accurate oil sales volume and amount of oil are notified to related organizations in real time, so that the oil market can be more easily managed. Through this, it is possible to grasp the circulation process of fake sales, unoccupied oil and fake oil, There is an advantage that hacking of the gasoline information can be prevented.
