Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an erroneous oil type unloading and an overflow prevention device when unloading a storage tank of a gas station.
[0002]
[Prior art]
The present applicant has proposed a wrong oil type unloading and overflow prevention device when unloading to a storage tank in a gas station as Japanese Patent Laid-Open No. 1-222692. This is effective, but data is exchanged between the control device on the filling station side and the control device on the lorry side via the signal line, so the signal line is connected before unloading and the signal line after unloading. It is necessary to remove. For this reason, unloading work increases, and if the lorry leaves without removing the signal line after unloading, the equipment will be damaged.
[0003]
[Problems to be solved by the invention]
The object of the present invention is to eliminate the inconvenience of the conventional example, and to perform data transfer between the control device on the filling station side and the control device on the lorry side without connecting signal lines, thereby simplifying the unloading work. and to provide a Ayamaabura species unloading and overflow prevention device capable.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, each oil storage tank is provided with an oil supply pipe, an oil supply pipe, and a liquid level gauge, a connection sensor is provided in a coupling of the oil supply pipe, and a connection signal of the connection sensor and The level signal of the level gauge is transmitted to the control device on the filling station side, and when the connection signal is input from the connection sensor, the tank data of this oil storage tank is sent to the control device of the lorry, and the load data is sent to the control device on the lorry side. And the tank data is displayed on the touch panel where the same oil type is loaded.
[0005]
According to the present invention, the control device on the filling station side that wirelessly transmits the tank data of a plurality of oil storage tanks, and the lorry side that prevents erroneous oil type unloading and overflow from the tank data and loading data received from the control device. Since it is composed of a control device, data can be exchanged without connecting signal lines, and unloading work can be simplified.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below. As shown in FIGS. 1 and 2, a plurality of oil storage tanks 2 </ b> A, 2 </ b> B, and 2 </ b> C (hereinafter, collectively referred to as reference numeral 2) are buried underground in a filling station 1 that supplies fuel oil to an automobile. For example, regular gasoline is inserted with a capacity of the oil storage tank 2A of 10 KL, high-octane gasoline is inserted with a capacity of the oil storage tank 2B of 5 KL, and light oil is inserted with a capacity of the oil storage tank 2C of 5 KL.
[0007]
Each oil storage tank 2 is provided with an oil supply pipe 3, an oil supply pipe 4, and a liquid level gauge 5. The oil supply pipe 3 is led out to the ground, and a connection sensor 7 is provided on the coupling 6 at the tip of the oil supply pipe 3. The oil supply pipe 4 is connected to a measuring machine (not shown) so as to supply oil from the measuring machine to the automobile. The connection signal of the connection sensor 7 and the liquid level signal of the liquid level gauge 5 are transmitted to the control device 9 via the signal line 8.
[0008]
The storage unit 9a of the control device 9 stores the capacity and oil type of each tank 2 as shown in FIG. 3, and stores tank data such as the current liquid amount and space capacity. The control unit 9b stores the current liquid amount calculated from the liquid level signal of the liquid level gauge 5 in the storage unit 9a and displays it on the display 10, and displays the current space volume calculated from the current liquid amount and the tank capacity. It memorize | stores in the memory | storage part 9a. When a connection signal is input from the connection sensor 7, the tank data of the oil storage tank 2 is transmitted via the transmission / reception unit 9c, and when the space capacity of the oil storage tank 2 becomes zero, a full tank signal is transmitted. Further, when an unloading data signal is input via the transmission / reception unit 9c, the unloading data is managed as purchase data.
[0009]
The tank 12 of the lorry 11 is divided into a plurality of hatches 13 </ b> A, 13 </ b> B, and 13 </ b> C (hereinafter, collectively referred to as reference numeral 13). The bottom valve 14 of each hatch 13 is connected to a discharge pipe 15, a coupling 16 is provided at the tip of the discharge pipe 15, and the coupling 16 and the coupling 6 are connected by an oiling hose 17 for unloading. It has become.
[0010]
In the storage unit 18a of the control device 18 of the lorry 11, loading data such as oil type and liquid amount of each hatch 13 is stored when loading at the oil tank station as shown in FIG. The control unit 18b displays the load data stored in the storage unit 18a on the touch panel 19 as shown in FIG. 5, and displays hatches that are loaded with the same oil type as the tank data received via the transmission / reception unit 18c. The tank data is displayed 19b at 19a. When the start switch 19c is pushed, the bottom valve 14 is opened, and when the end switch 19d or a full signal is received, the bottom valve 14 is closed. When the completion switch 19e is pressed, the unloading data is transmitted via the transmission / reception unit 18c.
[0011]
Next, the operation will be described based on the flowcharts of FIGS. When the driver of the lorry 11 who came to unloading to the gas station 1 connects the couplings 16 and 6 with the oiling hose 17, the connection signal of the connection sensor 7 is transmitted to the control device 9 of the gas station 1 (ST1 in FIG. 6), The control unit 9b transmits the tank data of the tank stored in the storage unit 9a via the transmission / reception unit 9c (ST2 in FIG. 6). Receiving this tank data, the controller 18b of the control device 18 of the lorry 11 (FIG. 7 ST1) displays the tank data 19b at the hatch display 19a where the same oil type as the tank data is loaded (FIG. 7). ST2). When the driver presses the start switch 19c (FIG. 7 ST3), the bottom valve 14 is opened and unloading is performed (FIG. 7 ST4). When the unloading of the hatch is completed and the end switch 19d is pressed (FIG. 7, ST5), the bottom valve 14 is closed (FIG. 7, ST6), and an end signal is transmitted (FIG. 7, ST7). Upon receiving this end signal, the control device 9 of the gas station 1 (FIG. 6 ST3) returns to step ST1.
[0012]
Similarly, the driver unloads the other hatch 13 (FIG. 7, ST8, ST2,...). When all the unloading is completed and the completion switch 19e is pressed (FIG. 7, ST9), the control unit 18b performs transmission / reception. Unloading data is transmitted via the part 18c (ST10 in FIG. 7). Upon receiving the unloading data, the control unit 9b of the control device 9 (FIG. 6 ST4) manages the unloading data as purchase data (FIG. 6 ST5).
[0013]
By the way, when the oil storage tank 2 becomes full during unloading and the space capacity becomes zero (ST6 in FIG. 6), the control unit 9b transmits a full tank signal via the transmission / reception unit 9c (ST7 in FIG. 6). The control unit 18b that has received the full tank signal via the transmission / reception unit 18c (FIG. 7, ST11) closes the bottom valve 14 (FIG. 7, ST12). When the full switch is noticed and the end switch 19d is pressed (ST13 in FIG. 7), steps ST7 and after are executed.
[0014]
As described above, since data exchange between the filling station and the lorry is automatically performed wirelessly, the lorry driver who arrives at the filling station can immediately carry out the unloading work. Also, since the tank data of the unloading storage tank is displayed at the hatch of the same oil type, the operability is good and the bottom valve cannot be opened unless the oil type is the same. There is no. Further, when the tank is full, the bottom valve automatically closes, so there is no overflow.
[0015]
【The invention's effect】
As described above, the erroneous oil type unloading and overflow prevention device of the present invention is based on a control device on the filling station side that wirelessly transmits tank data of a plurality of oil storage tanks, and tank data and loading data received from the control device. Because it is composed of a control device on the lorry side that prevents unloading and overflowing of wrong oil types, data can be exchanged without connecting signal lines, simplifying unloading work and ensuring safety Is.
