Description

[Detailed description of the invention] Industrial application field The present invention relates to an automatic ordering device for stored liquid, in which replenishment conditions are set for each day of the week or date, and based on these replenishment conditions, when the remaining amount becomes less than a predetermined amount. The present invention relates to an automatic storage liquid ordering device configured to automatically order storage liquid.

Conventional technology For example, in gas stations or boiler equipment,
When the remaining amount of oil stored in the tank falls below a predetermined amount, an order is placed for storing the oil. In this type of liquid storage facility, the person in charge of the facility generally checks the remaining amount of stored liquid on a regular basis, and when the remaining amount falls below a predetermined amount, the person in charge of the facility will confirm the type of oil, Orders for liquid storage were placed by contacting oil depots with information such as quantity and delivery date.

Problems to be solved by the invention However, in the above-mentioned case, the remaining amount of oil is manually monitored and ordered by a person in charge, so when checking the remaining amount of oil, it is difficult to check the remaining amount of oil. There was a problem that there was a risk of ordering errors such as making a mistake, ordering the wrong amount of oil when ordering oil, or delaying the order.

As an apparatus for solving such problems, there is, for example, an apparatus disclosed in Japanese Unexamined Patent Publication No. 59-51093. In this bulletin, the remaining amount in the tank is compared with the minimum stock liquid amount stored in the storage means, and when the remaining amount reaches the minimum stock liquid amount, a predetermined ordered amount is automatically sent to the oil depot. Configured to send.

However, at a gas station, the number of customers varies depending on the day of the week or date. For example, at a gas station at a recreational area, the amount of fuel supplied is larger than usual on Saturdays, Sundays, holidays, etc.

However, in the apparatus of the above-mentioned publication, although the amount of refueling varies depending on the day of the week or date, the minimum stock liquid amount and order amount (replenishment conditions) are constant regardless of the day of the week or date. Therefore, if the replenishment conditions are based on a normal day, the remaining amount in the tank may decrease faster than usual on Saturdays, holidays, etc., and there is a risk that delivery by tank truck may not be in time. In addition, if the replenishment conditions are based on Saturdays or holidays, or if a tank truck comes to deliver even though there is sufficient amount remaining in the tank, inconveniences may occur.

Therefore, an object of the present invention is to provide a storage liquid automatic ordering device that solves the above-mentioned problems.

Means for Solving the Problems The present invention comprises a remaining amount monitoring means for monitoring the remaining amount of liquid stored in a tank, a calendar device for counting days of the week and dates, and days of the week counted by the calendar device. replenishment condition storage means for storing, as replenishment conditions, a predetermined remaining amount of the tank and its replenishment amount, which are set in advance in correspondence with a date; The obtained remaining amount data is compared with a predetermined remaining amount corresponding to the day of the week and date stored in the replenishment condition storage means, and when the remaining amount data is less than the predetermined remaining amount, the replenishment condition storage means It consists of liquid storage ordering means for ordering a replenishment amount of liquid corresponding to the day of the week and date stored in the means.

Function: For each day of the week and date counted by the calendar device, the remaining amount in the tank is compared with a predetermined remaining amount that has been set in advance to correspond to that day of the week and date. You can order replenishment amounts that are set according to the
It is now possible to automatically order fluid according to the replenishment conditions according to the amount of refueling for each day of the week and date. Order.

Embodiment FIG. 1 shows a schematic configuration of an embodiment of an automatic liquid ordering device according to the present invention, and FIG. 2 shows a detailed configuration.

First, the general structure of the present invention will be explained with reference to FIG. 1, and then the features of the present invention will be explained.

The present invention has a configuration roughly shown in FIG.
In FIG. 1, a control device 1 includes a remaining amount monitoring means 4 which monitors the remaining amount of liquid stored in a tank 3 by receiving a signal from a liquid level gauge 2, and a remaining amount monitoring means 4 that monitors the remaining amount of liquid stored in a tank 3, and A replenishment condition storage means 5 stores a predetermined remaining amount of liquid as a replenishment condition, and a replenishment condition storage means 5 stores the remaining amount data from the remaining amount monitoring means 4 for each day of the week and date. and a storage liquid ordering means 6 that compares the remaining amount data with the replenishment conditions and orders the liquid when the remaining amount data corresponds to the replenishment conditions, and the remaining amount of the liquid is determined according to the replenishment conditions for each day of the week and each date for which the remaining amount data is set. When the amount falls below a certain amount, liquid is automatically ordered.

In Fig. 2, the underground tank 3 of the gas station is divided into three tanks 3a to 3c, each of which is divided into three tanks 3a to 3c.
The capacity of 3c is 10Kl each. For example, tank 3a
Different oil types are stored in the tank 3b, such as gasoline, high-octane gasoline in the tank 3b, and light oil in the tank 3c. The oil in the tank 3a is pumped up through the pipe 13a by starting the pump 12a in the metering device 11. That is, when a customer's vehicle (not shown) arrives at a refueling station, an operator disconnects the refueling nozzle 14a from the nozzle hook of the weighing machine 11 and inserts it into the vehicle's refueling opening. Therefore, the nozzle hook switch (not shown) closes and the pump 12a
starts. Further, by operating the nozzle lever of the fuel supply nozzle 14a to open a nozzle (not shown), the oil in the tank chamber 3a is supplied to the tank of the vehicle.

Further, a pipe 13b for feeding high-octane gasoline in the tank 3b and a pipe 13c for feeding light oil in the tank 3c are connected to the metering device 11'. The oil liquid in tanks 3b and 3c is connected to piping 13, respectively.
The oil is pumped up by the pumps 12b and 12c provided at the cylinders b and 13c, and is supplied to vehicles and the like. In addition, each tank 3a to 3c has liquid level gauges 16a to 16.
c has been inserted. These liquid level gauges 16a to 16c
is a capacitive liquid level detection sensor that outputs changes in capacitance according to the liquid level as a frequency signal. Each liquid level gauge 16a to 16c has a signal line 17a, respectively.
17c to the control device 1 installed in the office 18.

The control device 1 also controls each liquid level gauge 16a to 16c.
a remaining amount monitoring device 19 that is supplied with signals from the tank 3 through signal lines 17a to 17c, calculates the remaining amount of stored liquid based on the frequency signal, and monitors the remaining amount of stored liquid in each tank 3a to 3b; A memory (replenishment condition storage means) 20 that stores a plurality of replenishment conditions for each tank (remaining amount of stored liquid, etc.) for each day of the week, and a calendar that counts the day of the week and date and outputs a signal according to the day of the week and date. It has a device 21. The remaining amount monitoring device 19, memory 20, and calendar device 21 are
It is connected to the CPU 22, and the CPU 22 reads the day of the week and date from the calendar device 21 and stores it in the memory 20.
A replenishment condition is selected for each day of the week and date stored in the underground tank 3, and the replenishment condition and the remaining amount of liquid stored in the underground tank 3 are regularly compared. The CPU 22 has a liquid storage ordering function that outputs an order signal for the oil when the oil in the underground tank 3 decreases with the refueling operation and the remaining amount of liquid satisfies a selected replenishment condition.
The CPU 22 also includes a keyboard 23 for inputting various data, a printer 24 for printing order data on recording paper, and a transmission device for transmitting order data to an oil depot (not shown) or the like via a telephone line 25. 26 is connected.

Therefore, as will be described later, the control device 1 constantly monitors the remaining amount of liquid stored in each of the underground tanks 3, 3a to 3c, and when the remaining amount reaches the oil amount of the preset replenishment condition, it automatically Order oil liquid.

The keyboard 23 is shown in FIG. In FIG. 3, the keyboard 23 is provided with a display 27 for displaying numerical values, characters, etc. in response to each key operation, a numeric keypad 28, a plurality of function keys 29, and the like.
The function key 29 is the “remaining amount” key 29a
"Order quantity" key 29b, "Delivery date" key 29c,
"Calendar" key 29d, "Oil type" key 29
e, "Tank No." key 29f, "," key 29
g, "Inquiry" key 29h, "Clear" key 29
i, and a "setting" key 29j. In addition to inputting numerical values, each key of the numeric keypad 28 is also operated after the function key 29 is operated when inputting the day of the week and oil type.

Here, a description will be given of setting replenishment conditions for each oil type by operating each key on the keyboard 23. For example, at a gas station, there may be many customers before Saturday and Sunday, and relatively few customers at the beginning of the week after Saturday and Sunday. At such gas stations, the amount of refueling varies depending on the day of the week, so it is necessary to change the ordering data and replenishment condition settings accordingly.

FIG. 4 shows a table in which order data and replenishment conditions are set according to the customer situation. Fourth
In the figure, each tank 3a is
When ordering data such as tank number, oil type, and replenishment conditions for each day of the week (remaining amount, order amount, delivery date) are input to the control device 1, a table 30 of ordering data and replenishment conditions is created. and stored in the memory 20.

Here, the setting of the ordering data and replenishment conditions shown in FIG. 4 will be explained. The CPU 22 executes the processing shown in FIG. 5 in response to operations on the keyboard 23. In FIG. 5, when the setting work starts, the tank remaining amount setting is first read in step S1.
In step S1, each key on the keyboard 23 is operated in the following order. In other words, key 2 for “remaining amount”
9a, press the "2 fire" key, the "Kl" key, and the "setting" key 29j in sequence. By operating this key, the remaining amount of the tank is set to "2Kl". next,
By operating the keys "Order quantity", "8", "Kl", and "Set", the order quantity is set to "8 Kl" (step S2). After setting the order quantity, set the delivery date in step S3. i.e. "Delivery date", "2 Tue", "Settings"
By operating each key in order, the delivery date can be set to ``2''.
"days later" is set.

Next, in step S4, calendar settings are read. In step S4, "Calendar",
By operating the "January", ",", "2nd Tuesday", and "Set" keys, the replenishment conditions set in steps S1 to S3 above, such as remaining amount 2Kl, order amount 8Kl, and delivery date 2 days, are set. Set on Mondays and Tuesdays. After setting the calendar,
By operating the "Tank No.", "January", and "Setting" keys, the tank 3a of the underground tank 3 can be
No. 1 is set as the number (step S5).

Next, in step S6, the oil type settings for the tank No. are read. That is, in step S6,
By pressing each key in the order of "oil type", "0", and "set", the oil type of tank No. 1 is set to gasoline. Furthermore, if you press the "Settings" key,
The completion of setting work is read (step S7), and a table 30 of ordering data and replenishment conditions shown in FIG. 4 is created (step S8).

In this way, by operating each key on the keyboard 23, the replenishment conditions such as the remaining amount and order data regarding tank No. 1 are stored in the memory 20. In addition, in the explanation of Figure 5 above, the table of order data and replenishment conditions was created for only Monday and Tuesday, but for tank No. 1, the remaining tank amount, order amount, etc. are different for each day of the week. There is. Therefore, the above steps S1 to S8 are repeated for each day of the week (Wednesday, Thursday, Friday, Saturday, and Sunday) or for each date to create a table 30 of order data and supplementary row cattle corresponding to each day of the week and each date. do. In addition, the above table creation work for tank No. 1 can be performed for other tanks No. 2 and No.
Do the same for 3. The control device 1 automatically orders oil based on the table 30 of ordering data and replenishment conditions for each tank 3a to 3c created as described above.

If the table 30 is created using the date instead of the day of the week, for example, after operating the "calendar" and "9" keys in step S4, the numeric keypad 28 for the numerical value of the date may be operated.

Here, a description will be given of when ordering oil as the remaining amount of oil in each tank 3a to 3c decreases. 6 and 7 show the processing executed by the control device 1. In FIG. 6, the control device 1 executes processing for creating order data. First, in steps S10 and S11, the day of the week and date of the day are confirmed based on the signals from the calendar device 21, and replenishment conditions based on the signals from the calendar device 21 are selected. Then, tank No. 1 is designated (step S12), and the remaining amount set for that day of the week in tank No. 1 is read from the table shown in FIG. 4 (step S13).

Next, the remaining amount of tank No. 1 is read from the remaining amount monitoring device 19 to which the signals from each of the liquid level gauges 16a to 16c are input (step S14). Then, the remaining amount of the replenishment condition read from the table in step S13 is compared with the remaining amount of tank No. 1 read in step S14 (step S15). In step S15, the tank
If the remaining amount of No. 1 is greater than the remaining amount of the replenishment condition, that is, if it is a Monday, if there is a remaining amount of 2 Kl or more, the order flag is reset (step S16) and the tank No.
(Step S17). In this embodiment, since the underground tank 3 has three tanks 3a to 3c, N=3. Therefore, the steps
In S17, the process is executed for tank No. 1, so in step S18, the process is executed as tank No. 2.
Return to before S13. Then, the processing of steps S13 to S17 is repeated.

Further, in step S15, when the remaining amount in the tank 3a is, for example, 2 Kl or less and meets the replenishment condition, the order flag for the corresponding tank 3a is read out (step S19). Next, check that the order flag is reset (step
S20). In step S20, if an order for oil liquid for tank No. 1 has already been made, the order flag has not been reset, and in that case, the process returns to before step S17. In addition, when the oil liquid order for tank No. 1 has not been ordered, the order flag is reset, and in that case, the order data such as the order amount, delivery date, oil type, etc. for the corresponding tank No. 1 are displayed in the table shown in Figure 4. (step S21). Then, the order data read in step S21 is edited and created (step S22),
After setting the order flag (step S23),
Return to step S17.

In this way, follow the steps for each tank No. 1 to 3.
Execute the processing in S13 to S23, and in step S17
When No.=N, this process ends. The processes of steps S11 to S23 are periodically executed at predetermined time intervals, and each time the remaining amount of each tank 3a to 3b is compared with the remaining amount of the replenishment condition. When the remaining amount in the tank becomes less than the preset remaining amount, order data is created and an order flag is set. Also, to avoid creating order data to check periodically,
S20 prevents duplicate orders.

Next, the transmission of the order data edited and created in accordance with the procedure shown in FIG. 6 will be explained. The control device 1 executes the ordering process shown in FIG. In FIG. 7, order data is first read out (step S30). If the order data was created in step S22 and there is order data created in step S23,
It is determined that order data is available (step S31). In step S31, when there is order data, the order data such as oil type, order amount, delivery date, etc. by day of the week set in the table of FIG. 4 is transmitted to the oil depot via the transmission device 26 and telephone line 25 ( Step 32).
After transmitting the created order data, the printer 24 prints the order data, clears the order data (step S33), and ends the process. If it is determined in step S31 that there is no ordering data, the ordering process is ended without transmitting the ordering data.

Note that the above order data is edited and created in a predetermined area within the memory 20. Also, in the table in Figure 4, the amount of each tank 3a to 3c is 10Kl.
Therefore, the order amount is set to 8 Kl for the remaining amount of 2 Kl, and the order amount is set to 7 Kl for the remaining amount of 3 Kl. However, since the delivery date is two days after the order date, the customer's vehicle is being refueled during that time. Therefore, even if each tank has a capacity of 10Kl, the order amount is 8.5Kl for the remaining amount of 2KL, taking into account the reduction in delivery time.
Kl, the order amount may be set as 7.5 Kl for the remaining amount of 3 Kl.

Although the above explanation uses a gas station, it is not limited to this, and can be applied to any facility where, when the liquid in the tank decreases to a certain level, an appropriate amount is ordered externally to replenish the liquid. Of course, the ideas can be applied.

Effects of the invention As mentioned above, the liquid storage automatic ordering device according to the invention calculates the remaining amount in the tank for each day of the week and date counted by the calendar device to a predetermined amount that is set in advance in correspondence with that day of the week and date. Based on the results of this comparison, you can order a refill amount that has been set in advance for the day of the week and date. Orders can be placed automatically, and an appropriate amount can be automatically ordered depending on the replenishment conditions of the day, such as days when the amount of refueling is high or low. Therefore, for example, at a gas station in a recreational area, the system may be set to order a larger amount of fuel than usual on Saturdays or before holidays, or to order when a predetermined amount of fuel remains than usual. This system has the advantage of eliminating inconveniences such as not being able to deliver the tank truck in time, or when the tank truck arrives even though there is sufficient remaining tank capacity.
