Fig. 1 -is a block diagram showing an embodiment of the control device for a plurality of fuel dispensers, Fig. 2 is a block diagram showing construction of a microcomputer arranged in the control device in Fig. 1, Fig. 3 is a flow chart for showing operation of the dispensation controller in every dispenser, Fig. 4 is a flow chart for showing operation of the control device of the invention, and Fig. 5 is a flow chart for showing the other operation of the control device.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
In Fig. 1 each of the fuel dispensers I, II --- arranged in a gasoline station comprises a pump 1 for drawing fuel from a reservoir not shown, a motor 2 for driving the pump 1, a fuel flow meter 3 connected with the pump at the discharge side thereof and a nozzle 4 mounted at the free end of a flexible hose which is connected with the fuel flow meter 3 at the other end so as to dispense fuel to a motor vehicle not shown.
The fuel flow meter 3 is provided with a transmitter 5 for generating a pulse signal representing a fuel flow volume to be received by a dispensation controller 6, which is actuated by a nozzle switch 7 when the nozzle 4 is taken up from a hook 9 mounted on the housing of the dispenser. The actuated controller 6 calculates a fuel flow volume in reference to the pulse signal from transmitter 5 so as to show the result on an indicator 8.
A control device of the invention is generally represented by 20 6~ (~ ~~ '~: i and comprises a microcomputer 40 mounted in the casing thereof and a display panel 21 which is composed of a touch switch (such as a mat rix switch) 24 and a display means (such as a liquid crystal display, a cathode-ray tube and the like). The display means have a sectioned area 22 and a common area 26. The sectioned area 22 is divided into a plurality of sections, eight sections in the illustrated embodiment, which respectively corresponds to the plurality of dispensers I, II ---, eight dispensers in the illustrated embodiment, only two of which are shown for the sake of clarifying the drawing. ' Each section of the sectioned area 22 has an area 23a showing a number of the concerned dispenser, an area 23b showing a fuel flow volume and an area 23c showing situation or state of the concerned dispenser at the present, i.e. "Nozzle on Hook", "Nozzle Taken", "Dispensation Allowed", "Now Dispensing", "Emergent Stop" and the like respectively in the form of symbols understandable at a glance as shown in Fig. 4.
In an area 23d of every panel section, a memory or memories 41, 42 (Fig. 2) in the microcomputer 40 which have stored fuel flow volume are shown as explained later. Informations common to the all dispensers inclusive of the fuel volume of any of the dispensers which has finished its fuelling may be shown by request on the area 26 below the eight panel sections.
The control device 20 is provided further therebelow with a key board 28 which has switches 28a-28c and a ten-key board 28d. The control device 20 has also a printer 29 for issuing a payment slip.
First switch 28a is for selecting either of the two memories, second one 28b for setting printing means to issue the payment slip, and third one 28c for stopping all dispensers in emergency, e.g. when finding anyone smoking.
Now in reference to Fig. 2 showing arrangement of elements in the microcomputer 40 of the control device 20 of the invention, data as to the dispensed fuel flow volume is given by the dispensation controller 6 and sent through the line 10 (Fig. 1) to be stored in a first or second memory 41, 42. It is a reason why the two memories are provided that any dispenser having just finished its fuelling may be used at once by the second customer if the dispensed fuel volume is stored in the other memory. Thus, three or more memories may be provided if necessary.
The sectioned area 22 of the display panel 21 having eight sections is constructed also as a touch sensitive panel as said in the above so that, when touching any section of the panel with a finger, e.g. section "1", section judging means 45 connected therewith receive a signal therefrom so as~to identify the number and give a signal to comrnand output means 46 and symbol judging means 47.
The symbol judging means 47, on receiving a signal from the section judging means 45 and the controller 6, selects one of the symbols stored in a symbol memory 48, which is shown on the area 23c of a section of the display 21 through display driving means 44. The command output means 46, on receiving a signal from the section judging means 45, gives a command through the line 10 to the controller 6 of the concerned dispenser (e. g. dispenser I) by taking account of a signal given by the symbol judging means 45 which represents a current state of the dispenser.
Now in reference to Fig. 3, a flow chart showing the operation of the dispensing controller 6 in any of the dispensers and Fig. 4 showing the operation of the controll device 20 for the all, e.g. eight dispensers, when a customer selects any one of the dispensers, e.g. the dispenser I and takes the nozzle 4 out of the hook 9 in order to start fuelling, the nozzle switch 7 is turned ON (Fig. 3, Step 1) from the normal OFF state so that the controller 6 outputs a signal for demanding fuel dispensation (Fig. 3, Step 2), which is given through the line 10 to the control device 20 (Fig. 4, Step 1). In the control device 20, the supplied signal is transmitted to the symbol judging means 47 through a line 50. Symbol judging means 47 on receiving the signal selects the symbol corresponding to "Nozzle Taken" from symbol storing means 48 so as to correspondingly actuates means 44 for driving the display 21, whereby the symbol for the second mode is indicated on the area 23c of the display panel section "1" which is for the dispenser I
(Fig. 4, Step 2).
When a worker touches the display panel section "1" with his finger in reply to this reguirement by the customer (Fig. 4, Step 3), the corresponding signal is given to the controller 6 of the dispenser I
through section judging means 45 and command output means 46. In view of the state at that moment is that dispensation is being requested (Fig. 4, Step 4), the symbol on the area 23c is turned to the third mode, "Dispensation Allowed" (Fig. 4, Step 5).
When the signal for allowing dispensation is received (Fig. 3, Step 3), the controller 6 energizes the motor 2 for driving the pump 1 and sets the indicator 8 to "zero" (Fig. 3, Step 4). When the customer actuates the nozzle trigger to start fuelling, the controller calculates the fuel flow volume moment by moment in reference to pulse signals from the transmitter 5, the result of which is shown on the indicator 8 and sent to the control device 20 through the line 10 (Fig. 4, Step 10). In the control device 20, the signal of fuel flow volume from the line 10 is sent to the display 21 through the line 50, the symbol judging means _7_ 47 and the display driving means 44 to be indicated on the area 23b of the display panel section "1" and, at the same time, the symbol on the area 23c is turned to the fourth mode, "Now Dispensing" (Fig. 4, Step 11). The signal is also sent to either the first memory 41 or the second memory 42 which stores no data and vacant.
When the worker feels any danger to touch the section "1" of the touch sensitive panel 21 (Fig. 4, Step 3), the control device 20 outputs a signal for stopping dispensation of the concerned dispenser. In view of that the state is "Now Dispensing" (Fig. 4, Step 6) at that moment, the symbol is changed to one corresponding to "Emergent Stop" which is shown on the area 23c (Fig. 4, Step 7). When the controller 6 of the dispenser I receives the corresponding signal from the control device 20 (Fig. 3, Step 5), the pump motor 2 is stopped (Fig. 3, step 6>.
When the section "1" of the touch panel 21 is touched by the worker who has confirmed no danger, in view of that the state at the present is "Emergent Stop" (Fig. 4, Step 8) the control device 20 outputs signal for allowing dispensation again so that the symbol representing "Dispensation Allowed" as the third mode is shown on the area 23c (Fig. 4, Step 9). When the controller 6 receives such signal from the device 20 (Fig. 3, Step 7), the pump motor 2 is reenergized (Fig. 3, Step 8) without resetting the indicator 8 to "zero" and with continuing calculation of the fuel flow volume.
When the customer has finished fuelling and hung the nozzle 4 again on the hook 9, the nozzle switch 7 is turned OFF (Fig. 3, Step 9), and the dispensation controller 6 of the dispenser I deenergizes the pump motor 2 and outputs the corresponding signal (Fig. 3, Step 10).
When the control device 20 receives this signal through the line 10, (Fig. 4, Step 12), the data of dispensed fuel flow volume is settled in 2~~~~
_8_ the memory 41 or 42 and the concerned memory is shown on the display area 23d by an alphabetical letter "A" or "B" and the symbol in the area 23c of the section "1" disappears which means "Nozzle on Hook" (Fig. 4, Step 13).
Now in reference to Fig. 5, when the worker pushes a button of the ten-key board 27 for identifying the dispenser, namely "1" in this illustrated embodiment (Fig. 5, Step 1) and further the worker actuates the switches A or B of 28a in accordance with the indication appearing in the area 23d in order to select data of either of the memories 41 and 42, the dispensed fuel volume is shown on the area 26 in a larger scale (Fig. 5, Step 3). If he pushes the button switch 28b (Fig. 5, Step 4) under said condition, the payment slip is printed out (Fig. 5, Step 5) and the data in the selected memory is erased so that the display for the fuel volume on the area 26 is cleared off.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
In Fig. 1 each of the fuel dispensers I, II --- arranged in a gasoline station comprises a pump 1 for drawing fuel from a reservoir not shown, a motor 2 for driving the pump 1, a fuel flow meter 3 connected with the pump at the discharge side thereof and a nozzle 4 mounted at the free end of a flexible hose which is connected with the fuel flow meter 3 at the other end so as to dispense fuel to a motor vehicle not shown.
The fuel flow meter 3 is provided with a transmitter 5 for generating a pulse signal representing a fuel flow volume to be received by a dispensation controller 6, which is actuated by a nozzle switch 7 when the nozzle 4 is taken up from a hook 9 mounted on the housing of the dispenser. The actuated controller 6 calculates a fuel flow volume in reference to the pulse signal from transmitter 5 so as to show the result on an indicator 8.
A control device of the invention is generally represented by 20 6~ (~ ~~ '~: i and comprises a microcomputer 40 mounted in the casing thereof and a display panel 21 which is composed of a touch switch (such as a mat rix switch) 24 and a display means (such as a liquid crystal display, a cathode-ray tube and the like). The display means have a sectioned area 22 and a common area 26. The sectioned area 22 is divided into a plurality of sections, eight sections in the illustrated embodiment, which respectively corresponds to the plurality of dispensers I, II ---, eight dispensers in the illustrated embodiment, only two of which are shown for the sake of clarifying the drawing. ' Each section of the sectioned area 22 has an area 23a showing a number of the concerned dispenser, an area 23b showing a fuel flow volume and an area 23c showing situation or state of the concerned dispenser at the present, i.e. "Nozzle on Hook", "Nozzle Taken", "Dispensation Allowed", "Now Dispensing", "Emergent Stop" and the like respectively in the form of symbols understandable at a glance as shown in Fig. 4.
In an area 23d of every panel section, a memory or memories 41, 42 (Fig. 2) in the microcomputer 40 which have stored fuel flow volume are shown as explained later. Informations common to the all dispensers inclusive of the fuel volume of any of the dispensers which has finished its fuelling may be shown by request on the area 26 below the eight panel sections.
The control device 20 is provided further therebelow with a key board 28 which has switches 28a-28c and a ten-key board 28d. The control device 20 has also a printer 29 for issuing a payment slip.
First switch 28a is for selecting either of the two memories, second one 28b for setting printing means to issue the payment slip, and third one 28c for stopping all dispensers in emergency, e.g. when finding anyone smoking.
Now in reference to Fig. 2 showing arrangement of elements in the microcomputer 40 of the control device 20 of the invention, data as to the dispensed fuel flow volume is given by the dispensation controller 6 and sent through the line 10 (Fig. 1) to be stored in a first or second memory 41, 42. It is a reason why the two memories are provided that any dispenser having just finished its fuelling may be used at once by the second customer if the dispensed fuel volume is stored in the other memory. Thus, three or more memories may be provided if necessary.
The sectioned area 22 of the display panel 21 having eight sections is constructed also as a touch sensitive panel as said in the above so that, when touching any section of the panel with a finger, e.g. section "1", section judging means 45 connected therewith receive a signal therefrom so as~to identify the number and give a signal to comrnand output means 46 and symbol judging means 47.

The command output means 46, on receiving a signal from the section judging means 45, gives a command through the line 10 to the controller 6 of the concerned dispenser (e. g. dispenser I) by taking account of a signal given by the symbol judging means 45 which represents a current state of the dispenser.
Now in reference to Fig. 3, a flow chart showing the operation of the dispensing controller 6 in any of the dispensers and Fig. 4 showing the operation of the controll device 20 for the all, e.g. eight dispensers, when a customer selects any one of the dispensers, e.g. the dispenser I and takes the nozzle 4 out of the hook 9 in order to start fuelling, the nozzle switch 7 is turned ON (Fig. 3, Step 1) from the normal OFF state so that the controller 6 outputs a signal for demanding fuel dispensation (Fig. 3, Step 2), which is given through the line 10 to the control device 20 (Fig. 4, Step 1). In the control device 20, the supplied signal is transmitted to the symbol judging means 47 through a line 50. Symbol judging means 47 on receiving the signal selects the symbol corresponding to "Nozzle Taken" from symbol storing means 48 so as to correspondingly actuates means 44 for driving the display 21, whereby the symbol for the second mode is indicated on the area 23c of the display panel section "1" which is for the dispenser I
(Fig. 4, Step 2).
When a worker touches the display panel section "1" with his finger in reply to this reguirement by the customer (Fig. 4, Step 3), the corresponding signal is given to the controller 6 of the dispenser I
through section judging means 45 and command output means 46. In view of the state at that moment is that dispensation is being requested (Fig. 4, Step 4), the symbol on the area 23c is turned to the third mode, "Dispensation Allowed" (Fig. 4, Step 5).
When the signal for allowing dispensation is received (Fig. 3, Step 3), the controller 6 energizes the motor 2 for driving the pump 1 and sets the indicator 8 to "zero" (Fig. 3, Step 4). When the customer actuates the nozzle trigger to start fuelling, the controller calculates the fuel flow volume moment by moment in reference to pulse signals from the transmitter 5, the result of which is shown on the indicator 8 and sent to the control device 20 through the line 10 (Fig. 4, Step 10). In the control device 20, the signal of fuel flow volume from the line 10 is sent to the display 21 through the line 50, the symbol judging means _7_ 47 and the display driving means 44 to be indicated on the area 23b of the display panel section "1" and, at the same time, the symbol on the area 23c is turned to the fourth mode, "Now Dispensing" (Fig. 4, Step 11).
