Abstract

PURPOSE:To attain a small-sized device which performs the stock management also, by inputting liquid level data, which is measured by a liquid level measuring device in an underground tank, to an input/output device which is connected directly to an oil feeder to process various data of the oil feeder. CONSTITUTION:Various data, namely, the quantity of sales, the price, etc. accompanied with sales in oil feeders 1a-1b are displayed on a CRT14 by the control of a CPU17 and are stored departmentally in storage areas 18. A card is read by a card reader 10, and credit sale or cash sale is inputted on a keyboard 9. Besides this normal business, liquid surfaces of oil tanks 3 and 3' are detected by liquid surface sensors 19 and 19' and are subjected to A/D conversion in A/D converters 20 and 20' and are inputted to a memory 24, which is controlled by the CPU17, through explosion-proof barriers 22 and 22' and a switching circuit 23. A minimum oil quantity, a maximum oil quantity, and a maximum water quantity are inputted preliminarily to the memory from the keyboard 9, and a buzzer 12 is sounded when the quantity of oil is less than the minimum oil quantity or exceeds the maximum oil quantity or the quantity of water in the bottom part exceeds the maximum water quantity, and this state is displayed on a CRT14. Thus, the sales business and the stock management are performed with the small-sized device.

On the other hand, the upper part of the display screen 14 mainly forms a table area J\r16 for performing various processes, and human power data, manual instruction items, etc. are displayed here.

As shown in FIG. 2, the keyboard 9. Card reader I
The output signal from O is introduced into the control device (CPU) 17, and the output No. 1a from the control device 17 is sent to the data recorder 11, the alarm 12, the printer 13, and the CR'r.
Display i! ! 1lilj14 respectively.

The control device 17 also stores cumulative sales data storage area 18a for oil types such as gasoline and diesel oil, cumulative sales data data for l'J+ items such as batteries, tires, and accessories other than songs, and 01 rear 18b. Accumulated sales data 1. q++ ls and input/output − are sent back and forth.

The above is a description of the data output device conventionally used at the Kallin gas station and the flock related to the fueling machine connected to the device.

In the present invention, 11 capacitive liquid level sensors 19.19"... are installed in the underground tanks 3.3'...
A liquid level measuring device 21.21' is formed by installing several A-D converters 20.20''... in each, and digital signals from the converters 20.20''... The signal is sent to the PO via the explosion-proof barriers 22, 22'... and the J switching circuit 23.

Note that the liquid level measuring devices 21, 21', etc. are configured with intrinsically safe circuits. The above is the liquid level data manual means of the present invention.

- On the PO3Z side, each underground tank 3, 3"...
Record the minimum oil storage limit, maximum oil storage limit, and maximum water storage limit for 1. ■: Area 24a, each liquid level measuring device 21.21
” and the liquid level data input from each tank 3, 3'.
A liquid level data storage having an area 24b that stores a calculation formula for converting a liquid level into a liquid amount based on the diameter and height of ..., and an area 24c that stores the calculated liquid amount for each tank. A section 24 is formed, and input/output signals are exchanged between the storage section 24 and the control device 17.

' The area 24a serves as a liquid volume storage means for recording each liquid volume entered by the key fob 9, and the area 24b
is combined with the arithmetic function of the control device 17 to constitute liquid level-liquid amount conversion means.

In addition, in 11, can a liquid level-to-liquid amount conversion means be incorporated into the position measuring device? , 11, the signal input manually from the fixed device to the POS may be used as a signal.

Next, usage and operation will be explained.

First, to explain the sales process for refueling, if you remove the nozzle Harz 5 and refuel, each refueling machine 1a, lb.
The refueling interval is counted by the counting circuit.

When the nozzle harness 5 is connected to the nozzle hook 7 by one turn, a signal indicating that the nozzle is turned up (3) and the amount of oil to be supplied, which is calculated by the number Bl by the counting circuit, are transmitted to the switching circuit 8. On the other hand, the control device 17 sequentially sends a call signal to the switching circuit 8, and the amount of refueling of the refueling machine that has finished refueling is manually input to the control device 17.

Then, if you take the car I with the cart reader 10 and operate the keyboard 19, the types such as "1 cash" or "1 credit sale" based on the information hidden in the cart will be displayed in the display area 16 of the front and back screen ■4. Also displayed are the name of the cart operator, QURA type, refueling machine number, unit price, amount of refueling, amount of refueling, etc.

Further, these display contents are printed and issued on a slip from the link 13 when the key 90 is pressed (9), and are simultaneously stored in a storage medium such as a cassette cap of the data recorder 11 or a floppy disk.

Furthermore, the amount of refueling is shown in the cumulative sales data by item 1. It is stored in area 18a of section a 18.

When selling products other than music, such as tires, accessories, etc., input is made using the keyboard 9, and these sales data are cumulatively stored for each product in area L8b of the storage section 18. Similarly screen 14
, the printer 13 issues a slip, and the data recorder 11 stores the information in a storage medium.

Next, to explain the case of liquid level management in underground tanks, the area 24a of the storage unit 24 stores the minimum oil storage limit of each tank 3.3' (the minimum amount that requires refilling the tank) by pressing key 1 on the keyboard 9. For example, the maximum amount of oil that can be stored at the bottom of the tank (the maximum amount that will not overflow when refilling), and the maximum amount that will naturally accumulate at the bottom of the tank are stored as shown below.

Minimum oil amount Maximum song interval Water amount tank I 2. OkL 9.5 [, 0,05
KL tank 2 1.5[, 4,5KL 0.02
The liquid level of each tank is sent from the KL control device 17 to the switching circuit 23. For example, when (M %: for measuring the liquid level in tank 3 is transmitted, ?I) is transmitted sequentially.
The llk level of the pool measured by the k-plane sensor 19 and the llk level of the water collected at the bottom of the tank are measured by the eight-way converter 20.20'.
... is converted from analog signals 1 and 1 to dental frequencies and other signals, and sent to the control device 17 via the explosion-proof bar 1-22 and the switching circuit 23.

The control device 17 calculates the liquid volume using the frequency that indicates the 11ν position of the tank 3 multiplied by the liquid level drawn from the area 24b - 11ν kick calculation formula, and is written in the area 24c as 1, a. The currently calculated liquid volume is written as 1 or 0 in place of the previously measured llkM.Next, the calculated liquid volume is compared with the value stored in area 24a, and the value is exceeded. In this case, the control device 17 includes the annunciator 12 and the CRT.
On the display screen 14G, the sound of ``A12'' is heard, and on the screen 14, the finger of ENG IJ 715 is pressed.

In the above example, the areas 24C of the liquid level data records 1 to 24 record the calculated liquid volume. The liquid level sensor 19.19'... force) can be memorized and the liquid level can be adjusted as needed. .

Also, from Keychain 9, the desired time 11 (Illeε
J゛, If you enter 21:00 when the gas station closes and have the printer ■3 automatically print out the 11νM in the underground tank at that time every day, you can check the inventory in the underground tank at the gas station. Management becomes safer.

As stated above, the data output device for gas service stations of the present invention is capable of processing P, which conventionally only processed sales data.
Connect the underground tank liquid level measuring device to the oS and check the stock-m
Because of this, the displays and alarms, etc., are used as a means of operation.1. This is done by making the device smaller and cheaper by sharing the device with the sales data processing system and the inventory management system.
