Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shipping control system for an oil depot, and more particularly to a shipping control system for an oil depot which controls a gas purge operation and a refueling operation in the oil depot.

Conventional technology In gas stations, regular gasoline, high-octane gasoline,
A lorry for handling oil liquids of a plurality of oil types such as kerosene, light oil and the like is provided with a plurality of hatches. From the oil depot, the oil liquids of the plurality of oil types are supplied to each hatch of the lorry vehicle, loaded and shipped / delivered in accordance with an order from the gas station.

In addition, in order to efficiently deliver the oil liquid to a plurality of gas stations, there is a case in which oil liquids of different oil types previously loaded on the same hatch of the lorry vehicle are supplied and then shipped and delivered.

Oil liquids are usually classified into oils such as regular gasoline and high-octane gasoline and oils such as kerosene and light oil.When refueling and shipping oil types different from those loaded on the same hatch of a lorry vehicle, If the oils are different from the previous one, that is, if the hatch after the previous gasoline refueling and delivery is refueled with kerosene or light oil this time and shipped and delivered, refuel the hatch with this time kerosene or light oil to prevent danger The hatch must be gas-purged before.

Conventionally, as for the shipping management of an oil depot including such a gas purge, as shown in Japanese Patent Publication No. 1-346395, an identification card for a lorry vehicle that intends to perform a gas purge at a gas purge site provided for the oil depot. When a card reader (for example, a car number card) is read into a card reader, a gas purge control device provided at a gas purge station is connected to a shipping management device (host computer) provided at an oil depot office or the like for managing shipping of lorry vehicles. On the other hand, the identification code (for example, Rori vehicle No.) stored in the card in advance is reported,
As described above, the necessity of gas purge is determined based on the reservation information about the lorry vehicle sent from the shipment management device, and the gas purge is controlled. At this time, for the hatch that requires gas purging, the completion of gas purging is reported to the shipping management device via a communication line each time the gas purging for each hatch is completed, and the shipping managing device reports the completion of that hatch of the vehicle each time. The completion registration process of the gas purge was performed. Then, when a refueling request is made for the lorry vehicle from a refueling control device provided at an oil liquid loading site in the oil depot, the gas purging of the hatch registered for the lorry vehicle is performed based on the completion data, and the shipment management is performed. The device determines whether or not the gas purging operation of the hatch for which the gas purging of the lorry vehicle was required has been completed, and transmits a refueling permission to the refueling control device via the communication line only when the gas purging operation has been completed. Had become.

SUMMARY OF THE INVENTION However, in the conventional oil tank yard shipping control system, the gas purge completion registration process is performed in units of hatches of a vehicle, and therefore, for example, the number of hatches of one lorry vehicle is up to seven. In this case, the number of hatches for performing gas purging per vehicle is a maximum of 7 hatches, and the number of communication of purging completion per vehicle is 7 (maximum), and the communication amount between the shipment management device and the gas purge control device increases. . Therefore, the number of times of completion registration processing of the gas purge increases, the input of other reservations and the control of shipping are controlled, and the work of the shipping management apparatus connected to other gas purge controllers and a plurality of refueling controllers via communication lines. The processing is excessive for the gas purge processing device and the oil supply control device, and the processing efficiency and

Similarly, a card reader for reading data of the identification card is connected.

Next, a control configuration of the shipping system for an oil tank will be described with reference to FIG. In the shipment management device 12, a shipment plan file for each lorry vehicle 1 is created in advance based on an order from a gas station that is a delivery destination, and stored in a storage unit (not shown). When the driver of the lorry 1 arrives at the oil depot, the identification card is read by the card reader 13 attached to the shipping management device 12. Shipping management device 12
Causes the printer 15 to print the shipping slip of the lorry 1 stored in the various shipping / delivery data for the lorry 1 based on the shipment plan file based on the reading of the identification card. From the shipping management unit 12 when the output of the deliveries, the previous loading oil seed data for each hatch H ₁ to H ₇ of the lorry vehicle 1 stored in the shipment schedule file and the current loading oil seed data For each hatch, it is checked whether both loading oil types have an oil type relationship that requires gas purging.If it is determined that gas purging is necessary for loading this time, the gas purging required hatch No. (Steps S1 and S2), and the storage means stores the hatch number requiring gas purging and the fact that gas purging is not yet determined for the lorry corresponding to the lorry.

The driver of the lorry vehicle 1 looks at this slip, and if the gas purge is instructed, moves the lorry vehicle 1 to the gas purge site before going to the oil type loading site. Then, the driver first connects the grounding device 3 at the gas purge station, and
Read the identification card. Thereby, the gas purge control device 2 transmits the card data to the shipment management device 12 via the communication line 11 by the communication control means 2e (steps S3, S4, S5). The shipping management device 12 is a gas purge control device 2
Lori car 1 corresponding to the card data sent from
The hatch No. data required for gas purging is transmitted to the gas purge control device 2 via the communication line 11. The hatch number data required for gas purging is stored in the storage means 2c via the communication control means 2e (steps S5, S6, S7). The driver sets the gas purge pipe 9 to a hatch (H ₁
And inserted into to H _7), insert the appropriate hatch No. card 4a~4g hatch card reader 5 provided on the operator side of the gas purging tube 9 presses the gas purge start switch 6 (step S9). The gas purge control means 2b reads the hatch number signal by the hatch card reader 5 and compares it with the gas purge required hatch number data stored in the storage means 2c. The gas purge control unit 2b checks whether the hatch is a hatch that requires gas purging (step S10). If the hatch is necessary, the gas purge control unit 2b outputs a gas purge OK signal to the exhaust fan 8 to activate the exhaust fan 8. (Step S11). The gas purge control means 2b operates the exhaust fan 8,
When the purge is started and the output of the gas concentration sensor 7 is monitored and it is detected that the gas concentration in the hatch, that is, the gas concentration of the atmosphere discharged through the gas purge pipe 9 has become lower than the explosion limit, the gas purge is terminated. Then, the operation of the exhaust fan 8 is stopped (step S12). At this time, the end of purging of the hatch is stored in the storage unit 2c (step S13). Here, when the purging end of the hatch is stored in the storage unit 2c, the purging completion determination unit 2d stores the shipment management device stored in the storage unit 2c.
The data relating to the gas purge required hatch transmitted from 12 is compared with the gas purge end hatch, and it is determined that the gas purge for all the necessary hatches is completed (step
S14), and on the condition that the grounding device 3 is removed, the communication control means 2e transmits a gas purge completion signal for one lorry vehicle to the shipment management device 12 via the communication line 11 (steps S15 and S16). ), Together with gas purging required hatch data and gas purge end hatch data.
2c is initialized for the next gas purge operation.

On the other hand, the shipment management device 12 that has received the gas purge completion signal from the gas purge control device 2 stores the gas purge hatch No. of the lorry vehicle 1 previously stored in the storage means based on the data indicating that the gas purge has been completed for the lorry vehicle 1. And the memory indicating that the gas purge is not completed are erased (steps S17 and S18). When the driver operates the gas purge pipe 9 to complete the gas purge for all hatches requiring gas purge printed on the shipping slip, the driver removes the grounding device 3 and moves the lorry 1 to the oil liquid loading site. Let it.

After the driver moves the lorry vehicle 1 to the oil / liquid loading site, the driver attaches a grounding device (not shown) connected to the refueling control device 17 in the same manner as the gas purge control device 2 to the lorry vehicle 1. The identification card is read by the card reader 18 at the loading site. The refueling device 17 detects the attachment of the grounding device and transmits card data to the shipping management device 12 (steps S19 to S20).
Based on the card data transmitted from the refueling control device 17, the shipping management device 12 stores in the storage means whether or not the gas purging has not been determined for the corresponding lorry vehicle in the storage means, and whether or not the gas purge has been stored in the storage means. It is checked whether or not the gas purge is completed (step S23). If the gas purge is not completed, an error is notified and the hatch is not refueled (step S31). Is transmitted, and loading is permitted (step S24).

On the other hand, the refueling control device 12 that has received the loading data transmitted from the shipping management device 12 (consisting of the hatch for refueling and the data indicating the type of oil to be refueled, the amount of oil, etc.) for the lorry vehicle is Based on the loading data, it is confirmed that the interlock conditions such as the collation of the oil type of the loading arm with the oil type of the hatch to be loaded by the loading arm are released, and the pump and the fixed amount are checked. Drive the valve to load oil into the hatch (step
S25, S26). Then, it is confirmed whether or not the refueling has been completed for all the hatches to be loaded with the oil liquid of the lorry vehicle based on the loading data (step S27). Then, the refueling control device 17 transmits a loading end signal to the shipping management device 12 (step S28).

Then, the shipping management device 12, which has received the loading end signal,
The end of loading of the lorry is stored in the shipping schedule file (step S31).

As described above, in the present embodiment, the completion of gas purging for the lorry vehicle 1 that needs gas purging in the gas purge control device 2 is transmitted to the shipment management device 12 for each vehicle.
Since the number of transmissions can be reduced and the completion of the gas purge is determined, the processing in the shipping control device 12 does not become a load, so that an efficient shipping operation can be performed.

In the present embodiment, a gas purge completion signal is generated in the gas purge control device 2 after the gas purge is completed and transmitted to the shipment management device 12. However, no special gas purge control signal is generated, and the gas purge control device 2 After confirming the end of gas purging of the lorry vehicle by matching the hatch requiring gas purging with the hatching ending with gas purging, the result of this matching may be transmitted to the shipping management device as it is.

FIG. 3 is a block diagram of another embodiment. The same components as those in the block diagram of FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. The present embodiment is characterized in that the gas purge control device 2 and the refueling control device 17 can directly exchange communication data.

The control configuration of this embodiment will be described with reference to FIG.

First, in the present embodiment, the lorry vehicle 1 first enters a gas purge field provided near the entrance in the oil tank place. The driver attaches the earthing device 3 to the lorry 1 at this gas purge site,
Read the identification card in which the identification data of the Rori car is stored in the card reader 10. The gas purge control device 2 detects the attachment of the earth device 3 and the reading of the identification card (steps S32 and S33), and transmits the identification data to the communication control means 2e.
Is transmitted to the shipping management device 12 provided in the oil depot office via the communication line 11 (step S34).

The shipping management device 12 that has received the identification data from the gas purge control device 2 checks whether or not the lorry vehicle is registered in the shipping schedule file (steps S35 and S36), and the lorry vehicle corresponding to the identification data is shipped. NG indicating that shipment is impossible if the vehicle is not registered in the schedule file
While the data is transmitted to the gas purge control device 2 (step S37), if the lorry vehicle corresponding to the identification data is registered in the shipping schedule file, the current loading oil type and the previous loading oil type are registered. Each hatch is collated and a hatch requiring a gas purge is determined (step S40). If there is a hatch requiring a gas purge, the type of oil to be supplied to each hatch, including data on the determined hatch requiring a gas purge, The quantity data is transmitted to the gas purge control device 2 as the current loading data (step S4
1).

On the other hand, when the NG data or the current loading data is received from the shipping management device 12, the gas purge control device 2 uses the provided alarm (not shown) when the received data is NG data.
Informs that the lorry is not included in the shipping schedule and that loading is not possible (step S38,
39) When the loading data is received, the information is stored in the storage means 2c, and the information indicating the necessity of gas purging and hatch information including the hatch requiring gas purging is notified by the annunciator. And the driver of the Rori car,
If there is a hatch that requires gas purging based on the information of this alarm, the hatch card is read by a hatch card reader of the gas purge pipe 9 for each hatch of the lorry vehicle as in the first embodiment. A gas purge operation is performed (steps S42 and S43). Accordingly, the purge completion determining means 2d of the gas purge control device 2 compares the hatch for which the gas purging operation has been completed with the hatch requiring the gas purge transmitted from the shipment management device 12 stored in the storage means 2c. However, when it is determined that gas purging has been completed for all hatches that require gas purging, the purport is notified by a reporter and the gas purging of the loading data of the lorry vehicle previously stored in the storage means 2c is performed. The fact that the gas purge has been completed is stored in place of the necessary hatch data (step S45). In the above process, when unloading-free loading data requiring gas purging is transmitted from the shipping management device 12 to the gas purge control device 2,
Needless to say, the purge completion determining means 2d automatically adds the gas purge completion to the loading data and stores it in the storage means 2c. Then, the driver removes the grounding device 3 attached to the gas purge control device 2 from the lorry 1 and moves the lorry 1 from the gas purge site to the oil liquid loading site in the oil tank facility (step S45).

At the oil / liquid loading site, the driver attaches a grounding device (not shown) attached to the refueling control device 17 to the lorry vehicle 1 and causes the card reader 18 to read the identification card. In response to this, the refueling control device 17 confirms the installation of the grounding device and the reading of the card (steps S46 and S47), and if the mounting of the grounding device and the reading of the card are OK, the identification data of the identification card is transmitted. It is transmitted to the gas purge control device 2 to inquire whether or not there is loading data for which gas purging has been completed corresponding to the identification data (step S48).

The gas purge control device 2 receives the data, searches the loading data stored in the storage means 2 using the identification data as a key, searches for the loading data for which the corresponding gas purge has been completed, and reads the loading data for which the corresponding gas purge has been completed. If there is any, the gas purge completion data and the loading data consisting of the oil type and quantity for each hatch are transmitted to the inquired refueling control device 17, and the identification data stored in the storage means 2c is transmitted. Is cleared (steps S49, S50).

Then, the refueling control device 17 receives the loading data and notifies the driver of the hatch to be loaded and the oil type by using an alarm (not shown) connected to the refueling control device 17. Then, the driver inserts the loading arm of the matched oil type into the hatch while watching the notification content, and inserts the hatch card attached to the hatch into the loading arm as in the first embodiment. Refueling is carried out while being read by a hatch card reader (not shown) provided in the device. At this time, based on the hatch read by the hatch card reader, the refueling control device 17 checks and confirms the oil type corresponding to the hatch in the loading data and the oil type of the loading arm, and if both match, Then, the pump and the metering valve are drive-controlled for the hatch and the oil liquid is loaded by the quantity of the loading data (steps S51 and S52). When the refueling control device 17 confirms that the loading of the liquid has been completed in all the hatches to be loaded, the refueling data is attached with the identification data of the lorry and the refueling completion mark and shipped as refueling completion data. Transmit to the management device 12 (steps S53, S54, S5
Five).

Upon receiving the refueling completion data, the shipment management device 12 stores the fact that the lorry vehicle 1 corresponding to the data in the identification has been refueled in the shipment schedule file, and the printer 18 identifies the identification code (vehicle number) and the refueling data. Print out the shipping slip describing the information (steps S56 and S57). Along with this, the shipping management device 12 transmits a data storage OK to the refueling control device 17 (step S58). Then, the refueling control device 17 receives this, and reports the completion of refueling using the alarm (step S5).
9,60). Accordingly, the driver recognizes the completion of refueling, removes the grounding device, drives the lorry, and delivers the lorry to the customer's service station. Then, the refueling control device 17 recognizes that the grounding device has been removed after the refueling is completed, and prepares for the next refueling operation for the lorry vehicle 1 (step S61).

As described above, in this embodiment, the loading data can be transmitted from the gas purge control device 2 including the completion of the gas purge, so that the processing in the shipping management device 12 can be further reduced, and the oil tank The required shipping control system can be operated more efficiently.

According to the shipping system for an oil tank facility of the present invention, the end of the gas purge for each hatch of the specific lorry is stored in the gas purge ending storage unit, and the determination unit determines that all the gas purge operations for the specific lorry have been completed. At this time, the end data of all hatches stored in the gas purge end storage means by the transmission control means are collectively transmitted as a gas purge completion signal from the gas purge control device to the shipment management device or the refueling control device. The communication between the gas purge control device and the shipment management device or the refueling control device regarding the end of the gas purge is completed only once, and the number of transmissions regarding the gas purge is reduced,
The load on the data processing of the shipping management device is reduced, and the shipping operation on the lorry vehicle can be performed efficiently.
