Abstract

PROBLEM TO BE SOLVED: To prevent errors in discerning yes or no in execution of gas purging when loading is made at an oil tank station that is different from an oil tank station whereat previous loading is made. SOLUTION: A shipping system at an oil tank station is constructed of a shipment control device 4 for a shipping apparatus 1 set up at a shipping site, a hatch setting device 2 installed in an office separated from the shipping site and a host computer 3 serving as a shipment control computer. The hatch setting device 2 judges, based on trip information registered in reserved data, whether or not the previous loading to a tank truck 5 is made at another oil tank station. In the case where judgement is made that the previous loading to the tank truck 5 is made at another oil tank station, necessity of gas purging is assigned to each of hatches. Therefore, when the previous loading is made at another oil tank station, necessity of gas purging is set to the tank truck 5 regardless of the kind of oil on the previous loading, and thereby loading at a different oil tank station can be executed safely.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shipping system and, more particularly, to a shipping system configured to safely perform a shipping operation to a tank lorry vehicle in which the previous loading was performed at another oil depot.

[0002]

2. Description of the Related Art Tank lorry trucks for delivering oil such as regular gasoline, high-octane gasoline, kerosene, and light oil to gas stations, etc., are ordered after departure from oil tanks when each oil type is loaded at the oil tank. To the refueling station of each delivery destination where there was. Further, the tank lorry is provided with a plurality of hatches, so that one delivery can go around a plurality of gas stations.

[0003] On the other hand, a host computer provided at an oil depot stores reservation data created by an order from a customer, such as a gas station, and the shipping status of oil liquid to be shipped based on the reservation data for each tank truck. Is managed. Also,
At the oil depot, a hatch setting device that assigns how to load the oil type and quantity to each hatch of the tank truck based on the reservation data registered in the host computer is installed. In this hatch setting device, a delivery schedule of each tank truck is created from the reservation data of the day, and the oil type, quantity, and delivery destination to be loaded for each hatch in the first trip are allocated. If the reservation data remains after the first trip is created, the second and third trips are created and all the reservation data is allocated.

[0004] When the driver of the tank truck arrives at the oil depot, the driver receives the allocation slip created by the hatch setting device and moves to the shipping stage. afterwards,
When the tank lorry arrives at the shipping stage, the vehicle number card of the tank lorry is inserted into the card reader and the vehicle number code is read. As a result, the host computer at the oil depot outputs the reservation data including the reserved quantity set for each tank hatch for the tank lorry vehicle corresponding to the vehicle number code to the shipping control devices at a plurality of shipping stages.

[0005] As described above, the oil depot manages the reservation data to be delivered on that day for each tank truck.
The driver of the tank lorry vehicle will be scheduled to deliver on the allocation slip set by the hatch setting device (oil type, quantity,
Delivery of the oil liquid based on the delivery destination). However, depending on the delivery destination of the tank lorry, the vehicle may be delivered to a place far away from the oil depot, and the delivery efficiency is significantly reduced in consideration of the time required to return to the oil depot for the second loading. There are cases. In such a case, it is being studied to minimize the loss due to the movement of the tank truck by carrying out a second loading at another oil depot near a distant delivery destination.

[0006]

When the last oil type is gasoline, since the hatch is filled with highly flammable vapor, the hatch is purged with gas to remove the vapor in the hatch. There is a need to. Therefore, before loading the oil liquid on the hatch of the tank truck, it is necessary to confirm whether or not the previously loaded oil type is gasoline, and determine whether or not gas purge is performed.

[0007] Therefore, when performing gas purging, preload data indicating which oil type was loaded in which hatch in the previous loading is required. However, when the oil depots loaded at the previous trip and the current trip are different, the hatch setting device cannot recognize the preload data loaded at another oil depot. Therefore, the driver
Self-declare the type of oil that was previously loaded. And
The operator of the oil depot this time inputs the oil type for each hatch declared by the driver to the hatch setting device of the oil depot.

[0008] Therefore, the method of confirming the previous hatch information input to the hatch setting device has been limited to only verbal information of the driver, and it was necessary to judge that the report of the driver was correct. However, if the driver has incorrectly declared the previous hatch information, there is a risk that it is determined that gas purging is unnecessary even though the actual previous oil type is gasoline. In that case, in the conventional shipping system, if the previous loading data is not accurate due to a mistake in the driver's memory or the like, it may be determined that gas purging is necessary but gas purging is unnecessary, and the oil liquid may be loaded. .

Therefore, an object of the present invention is to provide a shipping system which solves the above-mentioned problem.

[0010]

In order to solve the above problems, the present invention has the following features. According to the present invention, in a shipping system in which oil is loaded on a hatch of a tank lorry by reservation data based on an order, whether or not the previous loading was performed at another oil depot based on the trip information registered in the reservation data. Determining means for determining whether or not the previous loading of the tank lorry vehicle was performed at another oil depot by the determining means;
A gas purge allocating means for allocating a gas purge to each hatch.

Therefore, according to the present invention, when the previous loading of the tank truck is performed at another oil depot, the necessity of gas purging is assigned to each hatch, so that the tank truck does not depend on the type of oil previously loaded. By setting to require gas purging, loading operations at different oil tank stations can be performed more safely.

[0012]

Further, the shipping stage 7 is provided with a reserved amount display 26 for displaying the type of oil to be loaded for each hatch assigned by the hatch setting device 2. Therefore, the operator operates the loading setting device 18 while viewing the display content of the reservation amount display device 26. Reference numeral 31 denotes a gas purging stage, which is provided in a place different from the shipping stage 7. The gas purging stage 31 is provided with a gas purging loading arm 32 for purging vapor remaining in the hatch of the tank truck 5.
When the oil liquid is loaded into the hatch of the tank truck 5 and the last loaded oil is the first petroleum (such as highly flammable gasoline), the inside of the hatch must be purged with gas to remove residual vapor. Must. Therefore, the driver of the tank lorry vehicle 5 needs to perform a gas purging operation on the gas purging stage 31 before proceeding to the shipping stage 7 when the slip created by the hatch setting device 2 includes a description of the need for gas purging.

In some oil depots, a loading arm 32 for gas purging is provided on the shipping stage 7. In this case, the hatch of the tank truck 5 can be gas-purged on the shipping stage 7. Here, a procedure for loading the tank truck 5 into the hatch will be described. When the tank lorry vehicle 5 arrives at the oil depot, the driver inserts the vehicle number card 27 issued for each tank lorry vehicle 5 into the card reader / writer 8 of the hatch setting device 2 and the vehicle stored in the vehicle number card 27. Read the number code.

The oil type and quantity to be loaded in each hatch of the tank truck 5 is assigned based on the information, and the printer 11 issues a slip on which the hatch information is printed with the assigned oil type and quantity for each hatch.

When the driver receives the slip, if there is a hatch loaded with gasoline in the previous loading operation, the driver moves to the gas purging stage 31 and inserts the loading arm 32 for gas purging into the hatch and inserts the gas in the hatch. Remove residual vapor. Then, the driver moves the tank lorry vehicle 5 to the shipping stage 7 when the gas purging operation for all hatches in which gasoline was loaded last time is completed.

Thereafter, the driver inserts the loading arm 25 of the shipping stage 7 into the hatch. Then, the quantity to be loaded is set by the loading setting device 18, and the start switch 18b is turned on. As described above, when the start switch 18b of the loading setting device 18 is turned on, the shipping control device 4 starts the pump 20, opens the metering valve 24, and starts loading. Then, the flow rate pulse from the flow rate pulse transmitter 22a of the flow meter 22 is integrated, and when the flow rate set by the loading amount setting switch 18a is shipped, the fixed quantity valve 24 is closed.

FIG. 2 is a block diagram showing connections between the devices of the shipping system. As shown in FIG. 2, the host computer 3 is communicably connected to a dispatch reservation computer 15 installed at a distribution center via a public line 13, and has a plurality of hatch setting devices 2 via a serial line 33. And is communicably connected to a plurality of shipping control devices 4 via a serial line 34.

FIG. 3 is a diagram schematically showing the notification data after hatch allocation transmitted from the hatch setting device 2 to the host computer 3. As shown in FIG. 3, the notification data 35 manages each hatch data Oil Seeds units inside the hatch information data D _1. When trip information loading previous is another oil bases, before (in this example, gasoline) cargo oil type code D ₂ forces the first petroleum rewritten oil type code. Also, be sure to perform the gas purge before performing a loading control and the gas purge presence or absence flag D ₃ to "Yes".

FIG. 4 is a diagram schematically showing card data in which the hatch assignment is determined by the hatch setting device 2 and the assignment data is written to the vehicle number card 27. As shown in FIG. 4, the card data 36 includes, in addition to the vehicle number, hatch information D including the number of hatches, a product code, and a quantity.
₄ is written. The card data 36 includes
The hatch information ultimate trip identification flag D ₅ judges as to whether or not the final trip information is written.

[0028] By ultimate trip identification flag D ₅ are written in this manner in the card data 36, it is possible to determine whether the last trip information from the vehicle number card 27. FIG. 5 is a diagram for explaining a data processing procedure of data communication between devices in the shipping system.

As shown in FIG. 5, the vehicle allocation reservation computer 15 creates reservation data according to an order from a gas station, and transmits the reservation data to the host computer 3 when the reservation data is created. The host computer 3 stores the received reservation data in the reservation file 3a of the storage device 3a. When the tank lorry vehicle 5 arrives at the oil depot, the vehicle number card 27 is inserted into the card reader 8 of the hatch setting device 2, and the reservation data allocation information acquisition notification is transmitted from the hatch setting device 2 to the host computer 3. Upon receiving the reservation data allocation information acquisition notification transmitted from the hatch setting device 2, the host computer 3 determines from the trip information of the corresponding vehicle whether the information is the trip information after loading at another oil depot or the final trip information. I do.

Then, the host computer 3 transmits the notification data 35 (see FIG. 3) including the pre-load information of the vehicle to the hatch setting device 2. The hatch setting device 2 stores the card data 3 written in the car number card 27 only when the loading trip information is instructed to be the final trip information.
6 (see FIG. 4) is written with the final trip identification flag.

Next, control processing executed by the CPU 12 of the hatch setting device 2 will be described. FIG. 6 shows C of the hatch setting device 2.
5 is a flowchart of a control process executed by a PU12.
In FIG. 6, the CPU 12 of the hatch setting device 2 executes step S1.
In (hereinafter, “step” is omitted), when the reservation data is received, the process proceeds to S2, and it is determined whether or not the vehicle number card 27 is inserted into the card reader 8 of the hatch setting device 2. In this S2, when the car number card 27 is inserted into the card reader 8 of the hatch setting device 2, the process proceeds to S3, and whether the trip information of the previous loading exists in the card data 36 read from the car number card 27 or not. Is determined.

In S3, when the trip information of the previous loading is present in the card data 36, the process proceeds to S4, and it is determined that the preload information of the card data 36 is valid. However, if the trip information of the previous loading does not exist in the card data 36 in S3, it is determined that the preload information is the information loaded in another oil depot, and the process proceeds to S5. Is determined as the first trip.

[0033] When this loading trip information in S5 is the first trip, the process proceeds to S6, determines whether ultimate trip identification flag D ₃ of the card data 36 is ON.
Then, when the ultimate trip identification flag D ₃ of the card data 36 is ON in step S6, the trip information of loading the last time is judged to be normal because the final trip information S4
To determine that the preload information of the card data 36 is valid as described above.

However, if the loaded trip information is not the first trip in S5, the process proceeds to S7. S7
Then, all the oil type codes in the preload information of the hatch are changed to first petroleum (gasoline in this embodiment). Therefore, even when the current loading trip information is not the first first trip, if the previous loading trip information does not exist, all the oil type codes of the hatch preload information are set to the first petroleum (gasoline in this embodiment). , All hatches of the tank truck 5 need to be gas purged.

Further, when the ultimate trip identification flag D ₃ of the card data 36 is off at S6, depots was performed the day before loading is determined as being the other oil bases, the process proceeds to S7,
Change all oil type codes in hatch preload information to first petroleum. Therefore, it is possible to depots performing the loading of the previous day by the ultimate trip identification flag D ₃ of the card data 36 to determine whether the other oil bases. When the oil depot where the loading was performed the previous day is another oil depot, all the oil type codes of the hatch preload information are changed to first petroleum (gasoline in this embodiment), so that the tank lorry vehicle is changed. All hatches 5 require gas purging.

In the next step S8, notification data including hatch preload information is received. Then, in S9, it is determined whether or not the current loaded trip information is the final trip information.
In this S9, if the loading trip information this time is the final trip information, the process proceeds to S10 and the vehicle number card 2
The final trip identification flag is written in the card data 36 stored in 7.

Then, in S11, the write information and the loading information are determined. If the current loaded trip information is not the final trip information in S9, the process of S10 is skipped and the process proceeds to S11 to determine the write information and the loaded information. As described above, by writing the final trip identification flag in the card data 36 stored in the vehicle number card 27, the vehicle number card 27 is inserted into the card reader 8 of the hatch setting device 2, and the previous loading is performed. It can be determined whether the operation was performed the day before. This makes it possible to identify the presence or absence of gas purging in each hatch.

In the description of the flow chart of FIG. 6, the case where the gas type is set to the first petroleum type to perform the gas purge before loading the oil liquid into the hatch is described as an example. The invention is not limited to this. For example, when the preload information of the hatch cannot be obtained, the gas purge required flag may be turned on. FIG. 7 shows the case where the serial line 33 between the dispatch reservation computer 15 and the hatch setting device 2 is disconnected.
3 is a diagram showing a display screen displayed on a display 9 of FIG. FIG. 8 is a diagram schematically illustrating a process of creating a space in the trip information and shifting subsequent trip information.

When the serial line 33 between the dispatch reservation computer 15 and the hatch setting device 2 is disconnected, the pre-load information cannot be obtained from the dispatch reservation computer 15. Therefore, the hatch setting device 2 creates a processing screen 37 as shown in FIG. 7 in order to make the trip information of an arbitrary vehicle vacant by itself and determine that the previous loading trip information is loading at another oil depot. .

In this processing screen 37, loading trip information C after loading at another oil depot is input to the input vehicle number B of the shipping date A on the screen, as shown in FIG.
As shown in (2), after the designated trip of the internal data, the data is automatically shifted by one trip. This allows loading at another oil depot. In the case of FIG.
When up to 6 trips are reserved and 4 trips are input as empty trips by the hatch setting device 2, the 4 trips of the vehicle number are set to an empty state, and
Shift ~ 6 trips to 5 ~ 7 trips one by one.

Therefore, the driver of the tank lorry vehicle 5 can be loaded at another oil depot with four vacant trips. Further, even when loading is performed at another oil depot, it is possible to prevent a part of the reservation data managed by the hatch setting device 2 from being omitted or forgotten.

[0042]

As described above, according to the present invention, when the previous loading of the tank truck is performed at another oil depot, the necessity of gas purging is allocated to each hatch, so that the oil loaded by the tank truck last is loaded. Regardless of the species, it is set to require gas purging, so that loading operations at different oil depots can be performed more safely. Therefore, even when the driver mistakenly remembers the oil type loaded in the hatch last time, the gas purge operation is always performed before loading, so that the oil liquid can be loaded more safely.
