Description

Metering oil supply monitoring device

The present invention relates to a quantitative refueling monitoring device, and in detail, it detects whether or not leakage oil is contained in the oil vapor recovered from the refueling port of a vehicle, and monitors the refueling to achieve a quantitative refueling, but focuses on a refueling controller that controls refueling. The present invention relates to a quantitative refueling monitoring device configured to provide a quantitative refueling monitoring function in conjunction with a leak recovery detection unit that generates a leakage determination and an emergency control signal.

'Oil vapor' is generated when fuel oil or the like is injected through a fine gap, or is generated through a process in which fuel oil or the like is vaporized by contacting high-temperature equipment. When the concentration of oil vapor is increased or high heat is applied in an enclosed space There is a danger of explosion.

In order to eliminate the risk, techniques for removing the vapor have been proposed, such as installing a vapor monitoring device or a temperature monitoring device or installing a facility for recovering the vapor. As such a conventional technology, there are Korean Patent Application Publication No. 10-2004-0020313, "Oil vapor inhalation device for oiler", Korean Patent Registration No. 10-0786623, "Ceiling type oiler having a vapor recovery function", and the like.

However, since the prior arts do not monitor the amount of leakage generated, there is a problem that the oiling worker and the driver cannot recognize it even if the quantity of oiling is not achieved.

As a technique for solving this problem, the present applicant has proposed Republic of Korea Patent Registration No. 10-1787688 "Vacuum recovery monitoring system". The prior art is configured to detect whether the leaked liquid is contained in the recovered oil vapor, to detect leakage during refueling, and to control the refueling situation.

However, in the prior art oil vapor recovery monitoring system, the applicant's own detailed implementation process, which is not premised on disclosure, has a detailed configuration of the oil pump to additionally install a leak recovery detection unit in a lubricator controller for controlling a conventional oil supply pump.

The additional direct lubrication pump is configured to control OFF (emergency operation).

However, at this time, the lubricator controller, which is in charge of the basic operation control of the lubricator, does not directly control the lubricating pump (emergency state operation), but the leakage recovery sensor directly controls the lubricating pump, so the lubricator controller does not control the overall control of the lubricator. There was a limit that it could not. For example, although the oiling controller continues to recognize the oiling pump as an ON control, the oiling pump may have a state in which the oiling pump is turned off by the leak recovery detection unit.

In addition, although the conventional lubricator configuration is made such that the conventional input and output means (user interface) of the lubricator is controlled by the lubricator controller, in the configuration where the leak recovery sensor directly controls the emergency state operation, the leak recovery sensor is separate It was necessary to provide or control the alarm display means.

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

1 is a schematic diagram of a metering refueling monitoring device installed in an oiling device according to an embodiment of the present invention.

Quantitative oil supply monitoring device according to an embodiment of the present invention is installed in the oiling device (F).

The lubricator device F includes a lubricating nozzle 200 and a lubricator 100. In FIG. 1, the lubricator 100 is shown as a stand type, but is not limited thereto, and a ceiling lubricator may also be regarded as corresponding to the lubricator 100 of the present invention.

The refueling nozzle 200 includes a supply unit 220 for supplying fuel oil to the refueling port A of the vehicle and a recovery unit 240 for recovering oil vapor from the refueling port A of the vehicle.

For example, the inside of the oiling nozzle 200 may be formed in a double pipe shape composed of a center pipe and an outer pipe surrounding the center pipe. The supply unit 220 for supplying the fuel oil may be understood as a center pipe, and the recovery unit 240 for recovering the vapor may be understood as an outer tube.

In FIG. 1, the oiling pipe 122 and the recovery pipe 124 are illustrated to be divided up and down to help understand, but when the oiling nozzle 200 is configured in the form of a double pipe, the oiling pipe 122 is the It is connected to the central pipe and provided on the inside, and the recovery pipe 124 may be provided on the outside in connection with the outer pipe to surround the central pipe. The mechanical configuration of the lubricator 100 or the lubricating nozzle 200 that is not described in detail in this embodiment may be referred to through Korean Patent Registration Nos. 10-1114971, 10-0262869, and 10-1439172. have.

The refueling machine 100 is connected to the refueling nozzle 200 and the refueling pipe 122, and the fuel oil is transferred from the storage 500 where the fuel oil is stored by the operation of the refueling pump 140 to the refueling nozzle 200. Supply and recover oil vapor from the oiling nozzle 200 by the operation of the recovery pump 160. For example, storage 500 may be an underground storage.

The recovery pump 160 is a pump having a function of a gas inhalation device (eg, an air pump) for inhaling and transporting vapor, and is configured to suck vapor from the outer end of the oiling nozzle 200.

However, when the unexpected leakage occurs in the outer end of the refueling nozzle 200, the inside of the refueling nozzle 200, the connecting portion of the refueling nozzle 200 and the refueling pipe 122, the operation of the recovery pump 160 By this, leakage fluid may be sucked into the recovery pipe 124 in addition to the vapor.

That is, the leaked liquid contained in the recovered product recovered by the recovery pump 160 may be understood as a problem when refueling, and the occurrence of the leaked liquid means that a fixed amount of refueling is not performed.

Therefore, it is preferable to take an emergency state operation, such as stopping refueling and / or outputting an alarm in the event of leakage.

The quantitative lubrication monitoring device of this embodiment includes a lubricator controller 410, a flow meter 180, a recovery unit controller 420, a leak detection sensor unit 300, and a leak recovery detection unit 430.

The lubricator controller 410 controls the oil supply pump 140 on (ON) or off (OFF). The lubricator controller 410 is for controlling the basic lubricating function of the lubricator device F, and receives the oil type and the lubricating amount of the fuel oil required to be lubricated by the operator or the customer through the input means 442 to receive the lubricating pump 140 Control. The input means 442 may be known user input / output interface means such as a touch panel.

For example, the lubricator controller 410 may be connected to a payment unit (eg, point of sales (POS), not shown) that calculates a lubricating amount according to the lubricating amount and allows payment to be made, and may be linked with a payment function related to lubricating. . In addition, the lubricator controller 410 may be connected to the management computer 600 of the gas station through a communication network to provide the lubricating data of the lubricator device F.

For example, the lubricator controller 410 may be configured in the form of a control board including a power supply unit, a central processing unit (CPU), a memory, and an input / output interface. As an example, the input / output interface may include an interface of a serial communication protocol such as RS422 / RS485 / RS232, and an interface of a serial bus standard such as USB.

The flowmeter 180 measures the flow rate of the fuel oil supplied from the refueling pump 140 to the refueling nozzle 200 and provides a flow rate measurement value to the refueling controller 410.

The recovery unit controller 420 controls the recovery pump 160 on (ON) or off (OFF) and turns on the recovery pump 160 based on at least the ON control of the refueling pump 140 ( ON) control. For example, the recovery unit controller 420 may be configured in the form of a control board including a power supply unit, a central processing unit (CPU), a memory, and an input / output interface.

The leak detection sensor unit 300 is connected to the recovery unit 240 of the oiling nozzle 200 through an oil vapor recovery pipe 124, and to the recovered product including the oil vapor recovered by the recovery pump 160 It detects whether leakage is included and detects whether there is leakage during refueling.

The leakage detection sensor unit 300 detects whether leakage is present at the time of refueling by detecting whether the leakage is contained in the recovered product including the vapor that is recovered by the operation of the recovery pump 160. Leakage fluid may be caused by a part of fuel oil leaking out or condensation of oil vapor, and may contain a trace amount of moisture generated by rain water or condensed water vapor. An exemplary configuration of the leak detection sensor unit 300 will be described later with reference to FIGS. 5 and 6.

The leakage recovery detection unit 430 receives the signal detected by the leakage detection sensor unit 300, generates an emergency state signal when it is determined to be leakage based on the received signal, and transmits it to the refueling controller 410 do. For example, the oil leakage detection unit 430 may be configured in the form of a control board including a power supply unit, a central processing unit (CPU), a memory, and an input / output interface.

In general, a lubricator controller 410 is installed in the lubricator device F to control a basic lubricating function. If the leakage recovery unit 430 that generates an emergency state signal when determining leakage is separately installed as in this embodiment, the interlocking centering around the lubricator controller 410 has the following advantages.

That is, when determining the leakage, the emergency state signal is generated by the leakage recovery detection unit 430, but the emergency control according to the emergency state signal is performed through the refueling controller 410 installed to control the basic refueling function in the refueling device F. Since it is executed, the normal refueling control and the emergency control in an emergency state can be integrally executed in the oiling controller 410 to fundamentally prevent collisions or contradictions between control operations.

In addition, the emergency state control function can be variously configured without changing the configuration of the lubricator controller 410 itself installed to control the basic lubricating function in the lubricator device F, and it is also simple to expand or modify the function. It has the advantage of being able to. This advantage is particularly useful when the oil vapor recovery and leak detection functions are installed in an existing oiling device without the oil vapor recovery function.

In one embodiment, the oiling controller 410 is turned on (ON) when the oiling operation start command is input after oil type and flow rate information is input through the input means 442. A control signal is output, and when it is determined that the flow rate measurement value provided from the flowmeter 180 after the refueling operation has reached the input flow rate input through the input means 442, it is turned off to the refueling pump 140 (OFF) ) Output a control signal.

In the above process, the recovery unit controller 420 is turned on to the recovery pump 160 upon detection of an ON control signal output from the refueling controller 410 to the refueling pump 140. Control signal is output. In one example, the recovery unit controller 420 is connected to the signal input side of the recovery unit controller 420 to the control signal line output from the lubricator controller 410 to the oil supply pump 140 to detect a control signal. have.

Thereafter, when the emergency state signal is transmitted from the leakage recovery detection unit 430 in the state in which the ON control signal is output, the lubricator controller 410 controls the OFF signal to the refueling pump 140. Output

In addition, the recovery unit controller 420, when detecting an OFF (OFF) control signal output from the lubricator controller 410 to the oil supply pump 140, the OFF (OFF) control signal to the recovery pump 160 Output.

In the case of the present embodiment, when an emergency state signal is generated from the leakage recovery detection unit 430, both the refueling pump 140 and the recovery pump 160 are controlled to be OFF to perform both refueling operation and oil vapor recovery operation of the fuel oil. Emergency state control is performed by stopping. This is an advantageous way to reliably implement the stop control according to the emergency condition and to handle the leakage problem.

In another embodiment, the oiling controller 410 outputs an ON control signal to the oil supply pump 140 when a command for starting oiling is input through the input means 442, and the flowmeter 180 When it is determined that the flow rate measurement value provided from the input flow rate input through the input means 442 has been reached, an OFF control signal is output to the oil supply pump 140.

In the above process, the recovery unit controller 420 is turned on to the recovery pump 160 upon detection of an ON control signal output from the refueling controller 410 to the refueling pump 140. Control signal is output.

Thereafter, when the emergency state signal is transmitted from the leakage recovery detection unit 430 in a state in which the ON control signal is output, the refueling controller 410 outputs an emergency state signal to the recovery unit controller 420. do.

In addition, the recovery unit controller 420 outputs an OFF control signal to the recovery pump 160 when sensing an emergency state signal output from the refueling controller 410.

In this embodiment, when an emergency state signal is generated from the leak recovery detection unit 430, the operation of the refueling pump 140 is not stopped and only the recovery pump 160 is controlled to be OFF, so that the refueling operation of the fuel oil is initially input. It continues to the flow rate, but controls the emergency state by stopping only the vapor recovery operation.

When the leakage amount, which is the standard for the emergency status signal, is set low, or when the refueling amount at the time of refueling has almost reached the completion of refueling of the input flow rate (e.g., 90% refueling progress), the fuel can be viewed as the state where the quantitative supply has been completed. It may be inefficient to stop all the refueling operations and check the operator. In such a case, the leakage recovery operation may be stopped once and control to complete the refueling operation so that leakage does not continuously occur.

In another embodiment, the oiling controller 410 outputs an ON control signal to the oil supply pump 140 when a command for starting oiling is input through the input means 442, and the flowmeter 180 When it is determined that the flow rate measurement value provided from the input flow rate input through the input means 442 has been reached, an OFF control signal is output to the oil supply pump 140.

In this process, when the emergency state signal is transmitted from the leak recovery detection unit 430 in the state in which the ON control signal is output, the lubricator controller 410 turns on the alarm to the alarm output means 446 (ON). ) Output a control signal.

The alarm output may include one of light (e.g., flashing warning light) or sound (e.g., sending a warning sound), and notify a refueling operator or driver that leakage has occurred or the refueling pump 140 stops operating. You can notify the state of being.

In the case of the present embodiment, when an emergency state signal is generated from the oil leakage detection unit 430, an alarm output may be made together with the stop control of the oil supply pump 140 and / or the recovery pump 160, or independently. When only the alarm output is made independently, it is advantageous for the operator to check the emergency condition and to handle the leakage problem directly.

Meanwhile, the above-described embodiment of FIG. 1 has been described with the emphasis on a control configuration executed from the viewpoint of local control in the lubricator device F. As a modified example, the control of the entire gas station management system perspective may be achieved by interworking with the gas station management computer 600 and / or the gas station operator's portable terminal 700.

Figure 2 is a schematic diagram of a metering oil supply monitoring device installed in the oiling device according to another embodiment of the present invention.

As illustrated in FIG. 2, the quantitative refueling monitoring device of this embodiment may further include a management sensor 450. For example, the management sensing unit 450 may be configured in the form of a control board including a power supply unit, a central processing unit (CPU), a memory, and an input / output interface.

The management detection unit 450 is connected to the management computer 600 of the gas station and the leakage recovery detection unit 430 through a communication network, respectively.

The management detecting unit 450 provides emergency state data regarding the transmitted emergency state signal to the management computer 600 when an emergency state signal is transmitted from the leak recovery detection unit 430.

Preferably, one management detection unit 450 is connected to a plurality of leak recovery detection units 430 respectively installed in a plurality of oiling devices F installed at a gas station, and the emergency state data transmits the emergency state signal It includes the unique identification information (eg, the unique ID number of the lubricator) of the leak detection unit 430.

Meanwhile, the management computer 600 may provide the emergency state data to the portable terminal 700 of a pre-registered fueling worker through a wireless communication network. The wireless communication network may include a mobile communication network such as LTE, a wireless Internet network such as Wi-Fi, and a local area network such as Bluetooth / Zigbee. Reference numeral 710 denotes a server for a mobile communication network.

The portable terminal 700 may be understood as a smart phone, a tablet, etc. on which a fueling management application is installed. For example, the refueling worker may be a gas station of a gas station, and in another example, in the case of a self refueling station refueling by the driver, the refueling worker may be a driver.

For example, when an emergency state signal is received from the management computer 600, the emergency state signal is transmitted through the wireless communication network according to the operation of the management program provided in the management computer 600. Can be delivered wirelessly. The refueling worker can check the mobile terminal 700, recognize that the refueling has been stopped due to leakage, and immediately follow-up (eg, refueling cost calculation, refueling nozzle 200 status check, etc.).

The management computer 600 may transmit a text message or the like based on the emergency state signal to the portable terminal 700 of the fueling worker.

In the case of the present embodiment, when an emergency state signal is generated from the leak recovery detection unit 430, the emergency state of each gas station device in the gas station is monitored by the management computer 600 of the gas station through the installation of the detection unit 450 for management. It can be grasped as a whole and has the advantage of being able to transmit information for emergency measures to gas stations.

The management detector 450 provides emergency state data regarding the emergency state signal to the management computer 600. For example, the management sensor 450 and the management computer 600 may be connected through USB.

In the case of the present embodiment, the lubricator controller 410 is connected to the management computer 600 of the gas station through a communication network to grasp the normal lubricating data of the lubricator device F, and from the oil leakage detection unit 430 When an emergency state signal is generated, it is advantageous in that an emergency state can be comprehensively grasped in the management computer 600 of the gas station through the management sensor 450.

Typically, the lubricator controller 410 may be connected to a management computer 600 of a gas station through a wired communication network for fueling data management. In the case of the present embodiment, the gas station controller 410 and the management computer 600 are already connected to the wired communication network, and the gas station is installed and connected to the wired leak detection unit 430 without burden of installing a wired communication network. There is an advantage that the management computer 600 of the gas station can easily recognize the emergency state signal through the wireless network.

Reference numerals 430a and 450a, which are not described, respectively, indicate a wireless communication module that is installed in the oil leakage detection unit 430 or the management detection unit 450 and enables wireless communication with each other.

5 is a partial cross-sectional view of a leak detection sensor unit according to an embodiment of the present invention. 6 is an operation state diagram of a leak detection sensor unit according to an embodiment of the present invention.

The leak detection sensor unit 300 separates the recovered water flowing into the housing 320 through the recovery pipe 124 into vapor and leakage.

For example, when the recovered water flows into the inlet pipe portion 340 through the recovery pipe 124, the oil vapor is discharged to the discharge pipe portion 350 by the recovery pump 160, and the leakage liquid is discharge pipe portion It cannot move to 350 and falls to the lower portion inside the housing 320 by its own weight.

At this time, the separated oil vapor is sent to the fuel oil supply side, and the leakage fluid is stored in the housing 320.

The fuel oil supply side may be, for example, a storage 500 or a refueling nozzle 200 or a refueling pipe 122, and the like, through a liquefaction device (not shown) to liquefy the vapor and reuse it as fuel oil. It is desirable to send it to the fuel oil supply side.

The leak detection sensor unit 300 detects whether the leak is greater than or equal to a reference capacity in the housing 320 to detect whether there is leakage.

As the term used in the present invention, the 'reference dose' is a detection reference value for confirming whether a fixed amount of oil is achieved, and for example, may be a specific amount set in advance regardless of the amount of oil.

The leak detection sensor unit 300 includes a leak detection sensor 360 that detects whether the amount of leakage stored in the housing 320 has reached a reference capacity.

As illustrated in FIG. 6, the leakage fluid sensing sensor 360 gradually increases the height of the leakage fluid D while the leakage fluid D is stored in the housing 320, and the height of the leakage fluid D As it increases, the floating body 368 rises together.

The leak detection sensor unit 300 may further include a snap ring 369 at a predetermined distance between the upper and / or lower portions of the floating body 368, and the snap ring 369 may include a floating body 368. It acts as a stopper to control the excessive rise or fall.

As shown in FIG. 6, the floating body 368 rises, and then a specific portion of the floating body 368 (eg, upper and lower middle of the floating body 368) at a position corresponding to a preset leakage height (h). Part), the switch contacts 362a, 362b are charged with different polarities by the induced magnetic force by the magnetic body 366, and the switch contacts 362a, 362b are pulled together by magnetic force to contact each other. Signal.

At this time, the leak recovery detection unit 430 receives the signal detected by the leak detection sensor unit 300, and generates an emergency state signal when it is determined to leak based on the received signal.

As an example, the determination of the leakage may be determined as leakage if the leakage is stored as much as the preset leakage height (h), and may be determined as not leakage if the leakage is not stored as much as the preset leakage height (h). have.

For example, the leakage recovery detection unit 430 may be set to be determined as leakage when the leakage amount reaches the height of the leakage liquid corresponding to a specific value (eg, 150 ml or 200 ml), regardless of the actual amount of refueling. At this time, this specific value (eg, 150 ml or 200 ml) is set as the reference dose.

In the leakage detection sensor unit 300 according to an embodiment of the present invention, the leakage detection sensor 360 receives the detection signal when the stored leakage D reaches the reference capacity, the leakage recovery detection unit 430 To be transferred to.

The leakage recovery detection unit 430 is configured to generate an emergency state signal when it is determined that the amount of leakage fluid corresponding to the detection signal is a preset reference capacity.

In a preferred embodiment, the leakage recovery detection unit 430 may be configured to generate an emergency state signal when the amount of leakage liquid corresponding to the detection signal exceeds a preset volume compared to a preset refueling amount.

The 'reference volume compared to the refueling amount' is to set the reference volume in proportion to the refueling amount, for example, an upper limit of an allowable error range that is recognized quantitatively based on a specific refueling amount (e.g., 20ℓ) specified in the refueling related regulations (example , 150ml).

The reference volume compared to the refueling amount may be set in a quantitative (eg, 150 ml) or constant (eg, 0.5%) concept.

For example, the preset leakage height (h) may be set based on the amount of fuel oil that corresponds to the upper limit of the allowable error range for the amount of oil when a fixed amount of oil is achieved, for example, when filling with 20ℓ The height of the leakage liquid corresponding to 150 ml may be set to be the height of the leakage liquid determined to be leakage, where 150 ml is set as a reference volume compared to a 20 liter refueling amount.

The subsequent process configuration according to the generation of the emergency signal is as described above.
