By the way, in the conventional kind of gas station, there existed the following problems.

The oil supply pipe and the oil hole for the purpose of lubricating the underground tank from the tank lorry are constructed separately from each tank tank even if there are a plurality of underground tanks storing the same kind of fluid. When lubricating underground tanks, each time the lubricated tanks were to be pumped, a coupling operation and a removal operation were required between the gas pit and the tanker tip of the tank lorry.

Therefore, the coupling work and the removal work are very complicated, and at the same time, the working time is long and the work efficiency is extremely bad.

When the number of lubrication to the underground tank by the tank lorry is large, it is easy to generate a misoperation in coupling the lubrication hose of the tank lorry with the lubrication port of the lubrication pipe. At the same time, the amount of fluid that flows when the tank lorry's fuel hose is removed from the fuel port is increased, and excessive injection is caused.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a refueling system that enables continuous oiling from a tank lorry to a plurality of underground tanks storing oils of the same oil type.

In order to achieve the above object, the present invention is based on the detection output of the tank is provided with a plurality of oil in the oil storage station, the oil reservoir supplied by the improver, and the liquid level detection means for detecting the level of the low oil fluid of each tank. Residual measuring means for measuring the remaining amount of the low oil of the tank and a common oil supply from the oil outlet and oil tank means that one side is the oil port, the other branch is in communication with each other into the tank for storing the oil of the same oil type And a valve provided at an upstream side of the oil outlet to each tank in the common oil supply pipe, and a tank identification data, oil type data, and oil supply data corresponding to a desired tank to be oiled from the oil tank means. Operation means for inputting a lubrication data, the lubrication data and the cup input by the operation means; Opening and closing of the valve corresponding to the remaining amount of the low oil amount of each tank measured by the amount measuring means is sequentially converted and controlled in the input order of the tank identification data, and the oil supplied from the oil tank means through the oil supply pipe is of the same oil type. It is characterized by comprising a control means for sequentially injecting into each tank for storing the oil.

When the operator according to the present invention inputs the fueling data by the operation means, the control means is in communication with each tank that stores the oil of the same oil type based on the remaining oil in each tank measured by the fueling data and the remaining amount measuring means Each valve of the pipe is opened and closed sequentially to inject the fluid from the tank means into the respective tanks sequentially. In this way, the oil can be continuously supplied to each tank storing the oil of the same oil type, and the work efficiency can be improved.

In this case, the oil seed key 32 is not limited to the illustrated type, but may be provided with a different oil seed key corresponding to the oil kind handled by the gas station, and the voice generator 40 is not limited to a buzzer, Other alarm means may be provided.

Next, the operation of this embodiment by the above configuration will be described with reference to the flowcharts of FIG. 4 and FIG.

When the tank lorry 14 enters the oil supply station with the order of the oil from the oil supply station as the oil company oil tank, the input guidance message "password input" is displayed on the display 31 of the external manipulator 7 (step SA1). ).

For this reason, when a worker inputs a password from the column key 33 of the external operator 7 and presses the password input key 36 (step SA2) and presses the setting key 37 (step SA3), The password is transmitted to the indoor control unit 2. The indoor control unit 2 determines whether or not the password is correct (step SA4), and if it is determined that it is not correct, displays the message "password miss" on the display 31 (step SA5), and generates the voice generator 40. After a long buzzing sound (e.g. for a few seconds) and informs the worker that the password is missed (step SA6), the process returns to step SA1 to wait for re-entry of the password and determines that the password is correct. In one case, the message 31 is displayed on the display 31 (step SA7).

The indoor control unit 2 determines whether or not the worker presses the arrival key 34 according to the message of the step SA7 (step SA8), and when it determines that the arrival key 34 is pressed, the indicator 31 is displayed on the display 31. The message "Type of oil input" is displayed (step SA9).

As a result, when the worker presses the oil (key in the present embodiment of the oil lubricated in the underground tanks 10 and 11) 32 (step SA10), the indicator 31 displays the message "Tank No Input". Is displayed (step SA11).

Thus, the worker enters the tank No (No. 1, No. n in the present embodiment) from the hot key 33 (step SA12) and presses the setting key 37 (step SA13). In this case, when tank No is continuously input from the hot key 33, it is stored in the memory of the indoor control part 2 in order of input.

Next, the indoor control unit 2 determines whether or not the input tank No of step SA12 is the correct tank No. When it is determined that the correct tank No is again, the oil type and the step which are preset and stored in the memory corresponding to the correct tank No are again. By pressing the oil kind key 32 in SA10, it is determined whether the oil kind set and input is identical (step SA14).

As a result, when the correct tank No is not input or the correct tank No is input but it is determined that the oil type does not match in both, the display 31 displays the message "Input miss, re-input" (step SA15). ), A long (for example, several seconds) buzzer sounds are generated from the voice generator 40, and the operator is notified of an input miss (step SA16).

On the other hand, when the indoor control unit 2 determines that the tank No. is the correct tank No in step SA14, the operator determines whether or not the operator performs continuous input of the tank No. (step SA17).

If the worker performs continuous input, the process returns to step SA11 to perform the next input operation. On the other hand, when continuous input is not performed, the setting key 37 is pressed (step SA18).

Next, the indoor control unit 2 uses the liquid level meter 3 based on the remaining amount of liquid in each of the underground tanks 10 and 11 measured by the detection signals of the liquid level sensors 20 and 21, so that the input oil flow rate is equal to the underground tank ( In the case of the present embodiment, it is determined whether the oil supply amount of No. 1, No. n is appropriate (step SA22), and when it is determined that the oil supply amount is not suitable, the process proceeds to step SA15. When it is determined that the oil supply amount is appropriate, the message "Oilation OK" is displayed on the display 31 (step SA23), and the buzzer sound is generated from the sound generator 40 for a short time (for example, several seconds) to supply oil. Inform the employee of OK (step SA24).

Then, when the series of operations (steps SA10, 12, 13, 18, 20, 21) are not performed within a predetermined time, the external manipulator 7 returns to the initial state (not shown).

On the other hand, when it is determined in step SA8 that the worker has not pressed the arrival key 34, the indoor control unit 2 determines whether the worker has pressed the confirmation key 35 (step SA25), and confirms the confirmation key 35 Is determined to be pressed, the message "Tank No input" is displayed on the display 31 (step SA26).

Thereby, the worker inputs tank No (No. 1, No. n in this embodiment) from the hot key 33 (step SA27), and presses the setting key 37 (step SA28).

The indoor control unit 2 judges whether the input tank No is the correct tank No. (step SA29), and if the input tank No is the underground tank of the input tank No. (No. 1, No. n in the present embodiment) ) Is displayed on the display 31 (step SA30). On the other hand, if it is determined that the tank No is not correct, the message 31 re-input of the input miss is displayed on the display 31 (step SA31), and the voice generator 40 is operated as long as the previous time (for example, several seconds). B) A buzzer is sounded and the operator is notified of input miss (step SA32).

When the series of operations (steps SA27 and 28) are performed within a predetermined time, the external manipulator 7 returns to the initial state (not shown).

On the other hand, when it is determined in step SA25 that the worker has not pressed the confirmation key 35, the indoor controller 2 determines whether or not the worker has pressed the end key 41 (step SA33). When it is determined that 41) is pressed, the process returns to the initial state (step SA1), and the message 31 shows a message "password input".

If it is determined that the end key 41 has not been pressed, the process returns to step SA7 described above and the operation acceptance wait state of the arrival key 34, the confirmation key 35 and the end key 41 (from step SA7 to 8). → 25 → 33 → 7). And even when the series of operation acceptance states are maintained for a predetermined time, the external manipulator 7 returns to the initial state (step SA1) (not shown in the drawings).

Before the valve treatment of the outdoor control unit, the no. 1 Valve for tank (15), no. Each valve of the oil supply pipe communicating with the tank 16 and the other underground tank is closed. The indoor control unit 2 is an underground tank (No. 1, No. n in the present embodiment) from the tank lorry 14 according to the data transmitted from the external manipulator 7 with the external manipulator operation processing. After determining that the furnace can be lubricated (step SB1), conversion control of the opening and closing of the valve for the underground tank is performed in the order of the tank No stored in the memory. In other words, the indoor control unit 2 is the first. 1 Operate the pneumatic valve (18) for underground tanks, 1 The underground tank valve 15 is opened (step SB2).

As a result, when the operator opens the manual valve 13 and starts the oiling operation from the tank lorry 14 to the oil supply pipe 12, no. 1 underground tank 10 is supplied with the fluid of the above-mentioned oil flow volume.

Next, the indoor control unit 2 measures the No. which the liquid level meter 3 measured by the detection signal of the liquid level sensor 20. 1 Based on the remaining amount of fluid in the underground tank 10, It is determined whether or not the underground tank 10 is filled (step SB3). The indoor control unit 2 is no. 1 When it is determined that the underground tank 10 has not become a full tank, it is determined whether the worker has pressed the lubrication completed key 39 (step SB4), and when it is determined that this key 30 has not been pressed, the No. 1 Operate the pneumatic valve (18) for underground tanks, 1 The underground tank valve 15 is closed (step SB5), and the valve control process is finished.

On the other hand, the indoor control unit 2 determines the No. 2 in step SB3. 1 If it is determined that the underground tank 10 is a full tank, the No. 1 Actuate the pneumatic valve 18 for underground tanks. 1 The underground tank valve 15 is closed (step SB6). Next, the indoor control unit 2 determines the No. based on the stored contents of the memory. 1 It judges the presence or absence of valve setting other than the valve 15 for underground tanks (step SB7); If no valve is set, the valve control process ends. If there is a valve set, the valve for the underground tank to be opened next is set. It is set to n (step SB8).

Next, the indoor control unit 2 has a no. n Activate the pneumatic valve (19) for underground tanks and n The valve 16 for underground tanks is opened (step SB9).

As a result, the tank lorry 14 passes through the lubrication pipe 12 to form a No. The n-base tank 11 is lubricated with the fluid for the designated oil flow rate.

Next, the indoor control unit 2 measures the No. 2 measured by the liquid level meter 3 according to the detection signal of the liquid level sensor 21. n Based on the remaining amount of fluid in the underground tank 11, No. n It is determined whether or not the underground tank 11 has become a full tank (step SB10). n Operate the pneumatic valve (19) for underground tanks n The underground tank valve 16 is closed (step SB11). Subsequently, the process returns to step SB7.

On the other hand, the indoor control unit 2 is no. If it is determined that the underground tank 11 is not a full tank, it is determined whether or not the worker has pressed the lubrication completed key 39 (step SB12). 1 Operate the pneumatic valve (19) for underground tanks, 1 The valve 16 for underground tanks is closed (step SB13), and a valve control process is complete | finished.
