And a plurality of fuel supply units 50 ₁ to 50 _n are communicably connected.

  Here, the arrangement of each device arranged inside the housing 70 will be described. FIG. 5 is a BB cross-sectional view of the internal configuration of the housing as viewed from the front. FIG. 6 is an AA cross-sectional view of the internal configuration of the housing as seen from the side. FIG. 7 is a bottom view of the housing as viewed from below. FIG. 8 is an enlarged view of the heater unit arranged at the bottom of the housing.

  As shown in FIGS. 5 to 8, an air supply port 74 to which the compressed air supply path 22 is connected and an electric system connection port 76 to which an electric system such as the communication line 62 is connected are connected to the bottom of the housing 70. And are provided.

  A heater unit 83 is provided above the air supply port 74. The heater unit 83 includes an electric heater 84 and a heat sink 85. The air supply port 74 is attached below the electric heater 84 so as to face the central portion of the electric heater 84. The heat sink 85 is attached to the upper portion of the electric heater 84, and heat generated from the electric heater 84 is conducted to radiate heat to the upper printer 92.

  The air supplied from the air supply port 74 to the inside of the housing 70 collides with the center of the lower surface of the electric heater 84 and is dispersed in a horizontal flow, and also passes around the heat sink 85 and moves upward. At that time, the air flow from the air supply port 74 moves while taking heat in the process of passing through the heat sink 85.

  Further, the air flow heated by the heat sink 85 diffuses in the respective horizontal directions as indicated by arrows in FIGS. 5 to 8 and warms the entire surface of the printer 92 while convection in the housing 70. Accordingly, the heat of the electric heater 84 is transmitted through the air flow of the compressed air for the internal pressure explosion prevention, so that the printer 92 is heated efficiently as a whole. Therefore, even if the electric heater 84 is downsized, the printer 92 can be heated to a printable temperature, and power consumption can be saved.

  Moreover, since the air flow from the air supply port 74 convects the entire interior of the housing 70 as shown by the arrows in FIGS. 5 to 8, devices other than the printer 92 (control device 80, liquid crystal monitor 90, card) The reader unit 110 and the like are similarly heated. Thereby, even when the fuel supply management device 60 is installed in a cold region, the printing performance of the printer 92 is prevented from being deteriorated, and the fuel supply management control can be normally performed.

  The receipt issuing port 94 of the printer 92 is composed of a minute gap for the receipt to pass through, but is always open, so that a part of the air flow that convects the housing 70 passes through the receipt issuing port 94. Discharged outside. Thereby, since air convection in the housing 70 is promoted, it is possible to efficiently circulate hot air in the housing 70.

  Here, the fuel supply control process executed by the controller 80 will be described with reference to the flowchart shown in FIG. 10A to 10D show display examples of display screens displayed on the liquid crystal monitor 90 to be referred to in describing each processing of FIG.

  The controller 80 checks whether or not there is a fuel supply system that is being refueled by the nozzle 52 in S11 shown in FIG. In S11, when there is no fuel supply system during refueling (in the case of NO), the process proceeds to S12 and the initial screen 200 is displayed (see FIG. 10A). The initial screen 200 displays nozzle numbers 01 to 08 corresponding to the nozzles, and oil type buttons 211 to 218 on which the names of oil types to be supplied by the nozzles 52 are displayed. Further, a message such as “Please read the card” is displayed in the guidance area 209 formed at the top of the initial screen 200. The driver of the vehicle T calling this message passes the ID card issued by the company through the card insertion slot 102 of the outer card guide 100 and reads the identification data stored in the ID card.

  Further, in FIG. 10A, on the initial screen 200, the official oil type names such as high-octane, regular, light oil, kerosene, heavy oil, oil, and high-octane light oil are displayed on each of the oil type buttons 211-218. In addition, the display columns of the nozzle numbers 01 to 08 corresponding to the oil type buttons 211 to 218 are highlighted for the nozzles that are being refueled (for example, the nozzle number column that is being refueled is brightly illuminated, or red or orange) Display in a conspicuous color.

  Further, in S11, for example, when the nozzle hooking switch is on, or when the refueling end is not transmitted after the refueling permission is output, it is determined that there is a fuel supply system that is being refueled (in the case of YES), In step S13, a setting content screen is displayed on the liquid crystal monitor 90. In the setting content screen, the nozzle number display field for which the setting operation has been completed is highlighted (for example, brightly lit or displayed in a conspicuous color such as red or orange) to notify that it is in use.

  In next S14, it is checked whether or not the card data recorded on the ID card is read by the card reader unit 110 (whether or not the card data is input). When the card data is not input in S14 (in the case of NO), the process proceeds to S15, and it is checked whether or not the refueling by the nozzle 52 is finished and the actual refueling information is input. If the actual refueling information is not input in S15, the process returns to S14.

  When the card data is input in S14 (in the case of YES), the process proceeds to S17 to check whether the ID card identification data (card data) read by the card reader unit 110 is legitimate data. If the identification data (ID data) of the ID card is not regular data in S17 (in the case of NO), the process returns to S12 and the processes after S12 are performed again.

  If the identification data (ID data) of the ID card is regular data in S17 (in the case of YES), the process proceeds to S18, and an instruction to input refueling information (nozzle (fuel supply system), refueling amount, etc.) is displayed on the liquid crystal. It is displayed on the monitor 90. In S18, for example, the nozzle selection screen 210 is displayed on the liquid crystal monitor 90 (see FIG. 10B). Then, when the nozzle selection operation is performed, an oil supply amount selection screen 220 is displayed on the liquid crystal monitor 90 (see FIG. 10C). In the guidance area 209 of the oil supply amount selection screen 220, a message such as “Please select the oil supply amount” is displayed. Further, on the refueling amount selection screen 220, a 100 L (liter) selection button 221, a 50 L (liter) selection button 222, a 40 L (liter) selection button 223, a 10 L (liter) selection button 224, a full tank oil selection button 225, cancel A button 226 and an oil supply amount input button 227 for inputting (presetting) an arbitrary numerical value are displayed.

  As a method of selecting an oil supply amount on the oil supply amount selection screen 220, a 100L (liter) selection button 221, a 50L (liter) selection button 222, a 40L (liter) selection button 223, and a 10L (liter) selection button for selecting a predetermined quantity are used. A method for operating 224 to turn on, a method for selecting full fueling using the automatic valve closing mechanism of the nozzle 52 by operating the full tank fueling selection button 225, and a method for turning on the fueling amount input button 227. There is a method of selecting a preset refueling to input a desired quantity.

  When any one of the predetermined quantity selection buttons 221 to 224 is turned on, the oil type name corresponding to the selected nozzle number is displayed with an abbreviated name, and the selected oil quantity is displayed. A refueling amount confirmation screen is displayed on the liquid crystal monitor 90.

  In S18, when the oil amount input button 227 is turned on, the oil amount input screen 250 is displayed on the liquid crystal monitor 90 (see FIG. 10D). In the guidance area 209 of the lubrication amount input screen 250, a message such as “Please enter the lubrication amount” is displayed. In addition, on the oil supply amount input screen 250, a numeric keypad 252 for inputting a numerical value of an arbitrary oil supply amount, a numerical value display unit 254 for displaying the input numerical value, a clear button 256 for clearing the input numerical value, A determination button 258 that is operated when the input numerical value is correct is displayed.

  When a numeric value is input by operating the numeric keypad 252 and the enter button 258 is turned on, the process proceeds to S19, where it is checked whether the fuel supply information (nozzle number, fuel supply amount) has been input. In S19, when refueling information is not input (in the case of NO), the process returns to S18 to instruct input of refueling information.

  In S19, when refueling information (nozzle number, refueling amount) is input (in the case of YES), the process proceeds to S20, and refueling is performed on the fuel supply machine 50 having the selected nozzle 52 (fuel supply system). Send permission and refueling information. Then, the process returns to S11.

  In S15, when actual fueling information is input, the process proceeds to S21, and the input actual fueling information (nozzle number, oil type, quantity, card data, time, etc.) is stored in the storage device 120. Subsequently, the process proceeds to S22, and a slip on which the actual refueling information is printed is issued from the printer 92. Then, the process returns to S11.

  As described above, the control device 80 of the fuel supply management device 60 can set the oil type, the amount of oil supply, and the like for the selected nozzle by reading the card data stored in the ID card with the card reader unit 110. become.

  Next, an internal pressure explosion-proof control process executed by the control device 80 will be described. FIG. 11 is a flowchart for explaining the internal pressure explosion-proof control process executed by the control device 80.

  The controller 80 reads the pressure measurement value Pm of the pressure sensor 82 in S31. In next S32, the pressure measurement value Pm is compared with the preset internal pressure explosion-proof pressure reference value Po (atmospheric pressure), and when the pressure measurement value Pm is lower than the internal pressure explosion-proof pressure reference value Po (in the case of NO), Since there is a possibility that the vapor may enter the housing 70, the process proceeds to S33, and an alarm (an alarm sound or an alarm message is displayed) is issued.

  Thus, the operator (operator) who supplies fuel stops the fuel supply management device 60 (power off) so that the fuel supply management device 60 does not ignite the vapor by stopping the fuel supply. Then, the operator (driver) checks whether the seal portion of the casing 70 is damaged or deteriorated, and when safety is confirmed, turns on the power of the fuel supply management device 60. Restart the fuel supply.

  In S32, when the pressure measurement value Pm is higher than the internal pressure explosion-proof pressure reference value Po (in the case of NO), since the pressure in the housing 70 is maintained at the atmospheric pressure or higher, the process proceeds to S34 and the temperature sensor 86 is reached. The temperature measurement value Tm is read. In next S35, the temperature measurement value Tm is compared with the printer operation lower limit temperature To. If the temperature measurement value Tm is lower than the printer operation lower limit temperature To (in the case of YES), the process proceeds to S36 and the electric heater 84 is supplied. Turn on the power. As a result, the electric heater 84 is in a heat generating state, and the air supplied into the housing 70 from the air supply port 74 collides with the lower surface of the electric heater 84 and is dispersed in the flow in the horizontal direction. And move upwards. At that time, the air flow from the air supply port 74 moves while taking heat in the process of passing through the heat sink 85, diffuses in each horizontal direction, and convects inside the housing 70 while warming the entire surface of the printer 92. The entire interior of the housing 70 is heated by the convection of the heated air flow, and the printer 92 can be warmed to a printable temperature.

  In S35, when the temperature measurement value Tm is higher than the printer operation lower limit temperature To (in the case of NO), the process proceeds to S37 and the energization to the electric heater 84 is turned off. As a result, the electric heater 84 is stopped, and the temperature in the housing 70 can be prevented from becoming unnecessarily high, thereby saving power. Thereafter, the process returns to S31 and the processes after S31 are repeated.

  In the above embodiment, the configuration in which the electric heater 84 is provided below the printer 92 and the compressed air supply path 22 for supplying the compressed air is connected to the lower side of the electric heater 84 is described as an example. For example, when the compressed air supply path 22 is connected to the side surface of the housing 70, the electric heater 84 is arranged on the side surface of the printer 92, and the compressed air supplied from the compressed air supply path 22 causes the electric heater 84 to be connected. The printer 92 may be configured to warm the entire printer 92 as warm air that has passed and heated.

  In the above embodiment, the fuel supply system for supplying fuel such as gasoline or light oil has been described as an example. However, the present invention is not limited to this, and other fuels (for example, CNG, LNG, LPG, hydrogen, etc.) are used. Of course, the present invention can also be applied to the fuel supply system to be supplied.

  In the above embodiment, the fuel supply management device 60 is provided separately from the fuel supply device 50. However, the present invention is not limited to this, and the fuel supply management device 60 is housed in the housing of the fuel supply device 50. Of course, the present invention can also be applied to the integrated structure.
