Definitions

  • the present invention relates to a device for controlling the operating mode of a hydrocarbon dispenser with an electronic computer.
  • the invention relates to such a control device which can be used in particular in a hydrocarbon distributor in which there is a volumetric sensor making it possible to measure the volume of hydrocarbon distributed which comprises a mechanical outlet whose displacement is representative of the volume measured and a converter for associating with the displacement of the output member a number of pulses representative of the volume delivered.
  • the distributor also includes a set of electronic circuits which make it possible to calculate, from pulses representing the volume measured and from unit price information, the price corresponding to the volume distributed.
  • a first solution to solve this problem consists in designing from the start a distributor in which there is a first zone in which the members in which the hydrocarbon circulates are housed and a second zone in which all the electronic circuits are located, these two zones being separated by an oil vapor barrier that is an integral part of the distributor frame.
  • the generally adopted solution consists of enclosing all the electronic circuits in an explosion-proof box.
  • the mechanical output of the volumetric sensor enters the housing explosion-proof by a specially designed bushing.
  • This information mainly consists of the unit price of the hydrocarbon used to calculate the price of the hydrocarbon delivered from the pumped volume. The value of this information must of course be able to be modified.
  • Other information related to the operating mode may also have to be entered. For example, it is necessary to be able to control the distributor in autonomous operation or in self-service operation (remote reading). Many other information related to the operating mode must still be able to be supplied to the computer, in particular to control the display of the total volume debited during a given period or the total amount of the sums invoiced to users during this same period.
  • a first proposed solution consists in using push buttons which pass through the explosion-proof casing, while respecting the established rules retaining its explosion-proof characteristics. This requires, at each crossing, to provide special explosion-proof provisions and the structure of the housing is much more complex and the production thereof is therefore much more expensive.
  • Another proposed solution consists in using a single mechanical member which passes through the explosion-proof housing. Relatively complex combinations of movements of this mechanical member must be implemented to allow the introduction of all the necessary information. It is easily understood that such a single member is of a complex mechanical construction and that, in addition, maneuvering errors are likely to be frequent. In addition, the total number of different pieces of information that can be introduced by such a provision is necessarily limited.
  • an object of the invention is to provide a device for controlling the operating mode of the dispenser which makes it possible to simplify the production of the explosion-proof box, while allowing a large number of d to be introduced into the computer. 'information, or information values without complex manipulations.
  • control device does not include any movable member passing through the explosion-proof enclosure.
  • said beam is a coded infrared beam.
  • FIG. 1 we will describe the general structure of the operating mode control device and its arrangement relative to the entire distributor.
  • An ice 12 of the hydrocarbon dispenser is also shown.
  • the volumetric hydrocarbon sensor with its mechanical outlet member 16 has been symbolized at 14. It is of conventional type.
  • the sensor 14 is mounted on the hydrocarbon distribution pipe 18.
  • Inside the frame 10 there is also an explosion-proof box 20.
  • this is constituted by two half-shells 22 and 24 connected together by two flanges respectively referenced 22a and 24a and screwed together. Each flange has a joint of sufficient length to ensure the explosion-proof properties.
  • the front half-shell 24 of the explosion-proof housing 20 has a window 26 made of a material allowing the infra-red radiation to pass.
  • this window is arranged vis - à-vis the crystal 12.
  • the window 12 is protected by a cover insensitive to infrared and is accessible after opening a door from the distributor.
  • the window has characteristics which, moreover, ensure a sufficient mechanical resistance against a possible deflagration.
  • the window is, for example, made of ordinary glass having a thickness of 5mm. It is stuck in the explosion-proof housing 20 on its internal face.
  • calculation circuits 30 which receive on the one hand the information on the volume distributed, and on the other hand the: unit price information for developing the information corresponding to the price of the volume of hydrocarbon distributed. Electronic calculation circuits for hydrocarbon distributors are well known.
  • the information on the distributed volume is, for example, produced by an optical system 32 which converts the rotation of the shaft 16 into a set of electrical pulses, the number of which is proportional to the rotation and therefore to the volume delivered.
  • the device 32 is for example constituted by a disc 34 integral of the output shaft 16 and provided with slots which pass in front of an optical detector 36. The latter delivers an electrical pulse each time a slot passes in front of the detector 36.
  • Such a device is of course perfectly known per se .
  • the shaft 16 passes through the wall of the housing 20 via a bushing 37 having a flange of joint length sufficient to maintain the explosion-proof properties.
  • the operating mode control device making it possible in particular to apply the unit price to the calculation circuit 30 comprises on the one hand a portable box 40, therefore outside the distributor 10, and an assembly arranged inside the anti-box explosion 22.
  • the housing 40 essentially comprises a control and data input member constituted by the keys 42 of a keyboard, an infrared transmitter 44, and an electronic circuit 46 for converting the action on the control keys 42 in a coded infrared signal which will be delivered by the infrared transmitter 44.
  • the control device comprises an optical detector 48 arranged visually opposite the window 26 and therefore capable of receiving the infrared signals delivered by the box 40 when the latter is put in a suitable position, and an electronic circuit 50 for processing the electrical signals delivered by the optical detector 48.
  • the dispenser comprises a display device 52 for example constituted by an intrinsically safe liquid crystal cell and controlled by the computer 30 placed in the explosion-proof housing.
  • the device for controlling the operating mode of the dispenser comprises on the one hand, inside the explosion-proof box, an infrared beam receiver associated with a decoding circuit 50 and on the other hand a portable box 40 outside the distributor capable of emitting an infrared beam constituting a signal representative of the desired operating mode information.
  • the device comprises the window 26 formed in the explosion-proof box which allows the passage of the infrared beam inside the explosion-proof box.
  • the housing 40 is only used by the owner of the distributor when it is necessary to modify one or more operating mode information.
  • the new information is then memorized by the calculation circuits.
  • the invention effectively solves the problem posed since the window 26 does not in any way modify the explosion-proof properties of the explosion-proof housing 22 because it does not create any new passage. Furthermore, the coding of the information carried out using the housing 40 allows a large number of combinations and therefore a large number of different pieces of information. Finally, the use of this control device is very simple and very reliable since, in the embodiment described, it suffices to press the appropriate key on the keyboard 42.
  • the infrared transmitter assembly contained in the control unit 40.
  • a set of conductors 60 associated with the keys of the keyboard 42. These conductors are arranged in rows and columns. In the particular case there are 4 rows and 4 columns.
  • Each of the conductors is connected to one of the inputs 62 a at 62 h from a decoder 62.
  • This circuit 62 is for example of the SDA 2008 type manufactured by SIEMENS.
  • the decoder 62 is programmed to deliver on its output 62 i a serial pulse signal representing a binary code of 6 serial binary values associated with each combination of a line and a column corresponding to a key on the keyboard 42.
  • the circuit 62 receives also, on its input 62 j a clock signal for example at 455 kHz delivered by the resonator 64.
  • the circuit 62 uses a two-phase coding which is modulated by a carrier constituted by the frequency signal delivered by the resonator 64.
  • the circuit 62 is programmed to additionally deliver a pre-signal to activate the receiver and a start bit.
  • the circuit 62 is preferably supplied only when a key is pressed. It is on standby the rest of the time. For this, its 62 m power inlet is connected to ground by via a transistor 66 serving as a switch and controlled by the signal appearing on the output 62 k of the circuit 62 when a key is activated.
  • the coded signal appearing on the output 62 i of the encoder 62 is applied to the input of the amplifier constituted by the transistors 68 and 70.
  • the output 72 of this amplifier is connected on the one hand to two emitting diodes in the infra -red 76 and 78 connected in series via the resistor 74, and on the other hand, to an electroluminescent diode 77 via a resistor 79.
  • the diodes 76 and 78 are further connected to the supply voltage by a resistor 78 '.
  • the diode 77 serves as an indication of operation.
  • the emitting diodes in the infrared 76 and 78 emit infrared signals of sufficient energy, and representative of the coded signals delivered by the coding circuit 62. They constitute the transmitting means 44 of FIG. 2.
  • the receiver circuit 50 of FIG. 2 comprises a photo-diode 81 disposed opposite the window 26 constituting the optical detector 48 of FIG. 2. Its output is connected to the input of a circuit 80 consisting of a variable gain amplifier and a filter mounted in feedback. The output of circuit 80 is connected to the input of a decoding circuit 82.
  • This circuit is for example of the SAB 3271 type manufactured by SIEMENS. This circuit is tuned once and for all on the clock frequency of the transmitter by an oscillating circuit 83.
  • the output 82 a of circuit 82 delivers a coded serial pulse signal representative of the key pressed.
  • the circuit 82 also delivers on its output 82 b a clock signal which is applied to a circuit 84 for shaping and adapting the voltage level.
  • the output 82 a of the circuit 82 is connected to the input 86 a of a shift register 86 via a circuit 85 for shaping and adapting the voltage level.
  • the introduction of the serial information is controlled by the clock signal applied to the input 86 b of the register 86 via the shaping circuit 84.
  • These outputs 86 c at 86 h from circuit 86 are connected to the computer 30 which thus receives the operating mode information and in particular the information relating to the unit price of the hydrocarbon.
  • the register 86 also delivers on its output 86 i a signal I to control the introduction into the microprocessor 30 of the information contained in the register 86, and the processing of this information. Finally, the register 86 receives from the computer on its input 86 i a reset signal J when the whole of a code has been introduced into the microprocessor 30.
