Definitions

  • the invention relates to a device for dispensing liquid fuels from at least one storage tank by means of at least one nozzle provided with a fuel nozzle, the fuel is supplied through a fuel pump with the interposition of a measuring unit with pulse generator to determine the amount of fuel, which escaping from the tank to be filled air Gas mixture is sucked off via a arranged on the fuel nozzle Gasansaugö réelle, which is connected by a opening in a storage tank gas recirculation line with a Gasabsaugpumpe and wherein the Meßaggregat a computer is associated, which is connected via a network to a central computer.
  • Such devices for dispensing liquid fuels are known. They usually include at least one storage tank for regular gasoline, premium grade petrol, Superplus and diesel and in each case several dispensers for each of these types of fuel. The quantities of fuel delivered and the associated prices are displayed on a display for each pump together with the respective basic price. In order to comply with the legal requirements, the air-gas mixture escaping from the fuel tank to be filled during refueling is sucked off and returned to a storage tank. The power of the gas suction pump used for this purpose is controlled as a function of the flow rate of the fuel determined by the measuring unit.
  • the invention has for its object to provide a device of the type described above for dispensing liquid fuels, which can be composed according to the needs of any number of similar modules with the lowest possible wiring and installation costs.
  • the solution of this problem by the invention is characterized in that in each Meßaggregat a computer is integrated, based on the pulses of the pulse generator automatically using the respective Meßaggregat associated information about fuel grade and basic price records, consisting of address, data and check for both the displays associated with the respective dispenser and for controlling the fuel flow-dependent suction power of the associated Gasabsaugpumpe as well as for the central computer of the gas station, which are supplied via the network the intrinsically intelligent aggregates, such as displays, the gas recirculation control and the central computer.
  • This embodiment of the invention has the advantage that the use of similar modules with intrinsically intelligent devices corresponding to the respective needs facilities can be put together, where it is only required before startup, the computer of each, identical units with one of the task corresponding software equip.
  • the inventive development is thus not only reduces installation costs, but also the storage, since each device is composed of similar modules that are adapted only by appropriate software of each task.
  • the network is preferably implemented as a BUS system CANBUS.
  • a serial data exchange between the intrinsically intelligent aggregates of the fuel dispensers and the central computer takes place via this network, in particular for function monitoring, fault diagnosis of the units and optionally for remote calibration of the measuring units.
  • the illustrated embodiment schematically shows a ground tank 1 for a liquid fuel, such as gasoline, which is sucked via a fuel line 2 by a pump 3, which is driven by a motor 4.
  • the speed of this motor 4 is controlled by a dispensing valve 5, which is arranged at the end of the fuel line 2 designed as a flexible dispensing hose 2 a.
  • the amount of each discharged fuel is determined by a arranged in a housing 6 measuring unit 7, which is arranged in the fuel line 2.
  • a formed on the nozzle 5 Gasansaugö réelle is connected via a gas return line 8 to the underground tank 1.
  • a Gasabsaugpumpe 9 is arranged, the suction power is controlled in proportion to the determined by the measuring unit 7 fuel flow.
  • this Gasabsaugpumpe 9 is driven by an electric motor 10 whose speed is controllable.
  • only one Gasabsaugpumpe 9 is arranged per side of each tap, since usually only one car can be refueled per page.
  • the measuring unit 7 is connected to a pulse generator 11, wherein the measuring unit 7 and the associated pulse generator 11 each have a computer 12 is assigned.
  • this calculator 12 which consists of measuring unit 7 and pulse generator 11 aggregate unit to an intrinsically intelligent aggregate, since the computer 12 is not only used to process the pulses of the pulse generator 11 to measurement data.
  • the computer 12 is supplied with information about the type of fuel and the basic price, so that the computer 12 automatically from the pulses of the pulse generator 11 and the information about the type of fuel and the base price from the user determined to be paid price for the amount of fuel removed and controls a network 15, a display 15, which displays the amount and the associated price of each delivered fuel in addition to the basic price of each existing in the Erdtank fuel grade, which usually per nozzle 5 an indication 15 is provided. At taps, where can be fueled from two sides, each dispensing valve 5, two displays 15 are assigned.
  • data sets for controlling the dependent of the fuel flow suction of the gas suction 9 or to control the associated electric motor 10 are generated by the computer.
  • the data sets generated by the computer 12 consist of an address to be addressed aggregate address, the data to be transmitted and a check-check, with which the mentioned aggregate can check whether the data transmitted to this unit data have arrived completely and correctly.
  • This transmission of the data records takes place via the network 14, which connects the individual aggregates with each other.
  • each aggregate connected to the network has its own computer, such as the computer 9a for the gas suction pump 9 or the computer 1 5a for the displays 15.
  • the data sets generated in the computer 12 are supplied to the computer 9a, which controls the speed of the gas suction 9 driving electric motor 10 such that their suction power is proportional to the determined by the measuring unit 7 fuel flow, so that via the nozzle. 5 an air-gas mixture amount is sucked, which corresponds exactly to the output by the nozzle 5 amount of fuel.
  • a price display 16 with associated computer 16a, a fuel terminal 17 and via remote data transmission at least one computer 18 for a service station and diagnostic center can be connected to the network 14.
  • Tankers 17 are provided at dispensers that are operated directly by cash or smart cards.
  • the eigenintelligente design of the individual units makes it possible that when a change in the price of fuel this, for example, directly via the central computer 13 of the gas station or an external computer 18 at the oil company, which communicates with the central computer 13, transmitted to the computer 12 of the measuring units 7 so that they automatically calculate the amount to be paid by the customer on the basis of the new fuel price at the next refueling operation.
  • the intrinsically intelligent design of the individual units allows a data exchange for diagnostic and service purposes, such as the function monitoring of the individual units and the monitoring of the levels of the individual underground tanks.
  • the function monitoring of the displays 15 and / or the price lists 16 via the corresponding computer 15a and 16a in that, for example, the numbers represented by individual bars are monitored in terms of electricity, d. H. that when switching between black and white, a current must flow. If this is not the case, notes the respective computer 15a and 16a, which controls the display 15 and the price table 16 that this number is defective and reports this defect to the central computer 13 of the tank and / or directly to the computer 18th the service station or diagnostic center.
  • the central computer 13 of the tank system and / or via a Remote data transmission line to be communicated to the computer of a central monitoring point can be decided by the central computer 13 of the tank system and / or by a central monitoring point (calibration office), whether the respective correction factor of the piston diameter of a measuring unit 7 in the associated computer 12 are changed after a calibration comparison for relevant deviations should. Since the switching of the controllable valves can be carried out within a short period of time during breaks, a review of the measuring units 7 is possible at any time, without the staff of the calibration office must visit the individual tanks.
