Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shipping management apparatus, and more particularly to a shipping management apparatus for shipping management so that an oil type and a quantity of oil liquid contained in reservation data are loaded in a tank truck.

[0002]

2. Description of the Related Art In an oil tank, a tank truck is loaded with an oil liquid ordered from a delivery destination in each hatch and starts toward the delivery destination. Then, when the driver of the tank truck arrives at the gas station of the delivery destination, he / she performs the unloading work for unloading the ordered oil liquid in the underground tank of the gas station. When all the hatches of the tank lorry are emptied, the driver of the tank lorry returns to the oil tank and loads the hatched oil liquid. In this way, the tank truck transports the ordered oil liquid back and forth between the oil tank and the delivery destination.

On the other hand, in the oil tank place for loading the oil liquid on the tank truck, a customer code for specifying an order consisting of the oil type and quantity from the customer and the oil type and quantity corresponding to the order. A host computer is provided as a shipping management computer for storing as reservation data together with vehicle number data (lorry vehicle code) corresponding to the tank truck to be loaded. In addition, at the oil tank,
A hatch setter that sets the type of oil and the quantity that the reservation data registered in the host computer has in each hatch of the tank truck, and how much is loaded (this is called "hatch allocation") is set up.
The oil type and quantity for each hatch set by the hatch setting device are stored in the storage unit in the host computer as hatch allocation data together with the vehicle number data of the tank truck.

When the tank lorry vehicle returns to the oil tank, the hatch setting device reads the vehicle number data as the Lori vehicle code corresponding to the vehicle number of the tank lorry vehicle from the reservation data registered for each vehicle number of the tank lorry vehicle, Next, issue a voucher on which the delivery destination for delivery, reservation data, and hatch allocation are printed. Then, the driver of the tank lorry vehicle holds the slip and moves the tank lorry vehicle to the shipping stage for loading the oil liquid on the tank lorry vehicle.

When the tank truck arrives at the shipping stage, the vehicle number card of the tank truck is inserted into the card reader to read the vehicle number data. As a result, the host computer at the oil tank station outputs the hatch allocation data corresponding to the vehicle number data to the shipping control device installed on the shipping stage.

Next, the driver, after connecting the grounding device to the tank truck, inserts the loading arm of the oil type to be loaded in the hatch, and connects the hatch card reader provided in this loading arm to the filler port of the hatch. Have the reader read the hatch card that is attached. Then, the driver sets the loading amount by using the loading amount setting switch of the loading arm and operates the shipping start switch.

As a result, the shipping control device sets the oil type of the loading arm, the set loading amount, and the oil type and quantity corresponding to the hatch of the hatch allocation data, to the hatch concerned on the condition that they match. Load the oil solution in. That is, the pump that is communicated with the loading arm of the shipping stage and the opening of the metering valve are opened, and the oil solution is loaded into each hatch of the tank truck.

[0008]

At the oil tank station, the shipping control device configured as described above manages the shipping of the oil liquid, and the operator of the tank lorry vehicle always works with the hatch setting device. There is a problem that it is troublesome to get on and off the tank truck and move inside the office, because it is necessary to go to a place to receive the slip. Further, when a plurality of tank trucks arrive at almost the same time, it is necessary to wait in order, so it takes time to issue a slip in the office, and there is a problem that the loading of the oil liquid and the delivery to the customer are delayed.

The driver of the tank truck may not know where the next delivery destination is until he returns to the oil tank and receives the slip, and the next delivery destination may be near the previous delivery destination. However, in the past, tank lorry vehicles that had finished delivering oil liquid loaded in the hatch had to return to the specific oil tank location where the tank lorry vehicle was registered, so even if the tank tanker truck was located next to the next oil tanker, another tank tank could be used. Even if there was a location, it was necessary to return to the oil tank station where the tank truck was registered, and it took time to make a round trip between the delivery destination and the oil tank station, and delivery efficiency could not be improved.

Therefore, an object of the present invention is to provide a shipping management device that solves the above problems.

6 is a flowchart for explaining a processing procedure executed by the computer 6 and a processing procedure of the host computer 2. The control circuit 16 of the vehicle-mounted terminal device 4 and the host computer 2 are
Since the hatch allocation process is executed while transmitting / receiving data by satellite communication, the processes of FIGS. 6 (A) and 6 (B) are executed in parallel.

In step S1 of FIG. 4 (hereinafter "step" is omitted), the control circuit 16 makes a request for transmission of reservation data corresponding to the vehicle number of the tank truck. Therefore, the reservation data transmission request signal is transmitted from the vehicle-mounted antenna 11 of the tank truck 3 to the communication artificial satellite 10. When the communication artificial satellite 10 receives the reservation data transmission request signal transmitted from the vehicle-mounted antenna 11 of the tank truck 3, the communication artificial satellite 10 transmits the reservation data transmission request signal to the antenna 9 of the order receiving center 1 on the ground. When the reservation data transmission request signal is transmitted, the vehicle number of the tank truck 3 that has requested the reservation data is also automatically transmitted.

In the next step S2, it is determined whether or not the reservation file 2a of the host computer 2 has reservation data corresponding to the vehicle number of the tank truck 2 (oil type and quantity data ordered by the customer). There is. Then, if there is no reservation data for the tank truck 2, the flow advances to S13 to display on the liquid crystal display 15 of the vehicle-mounted terminal device 4 that the delivery work of the day has been completed.

Now, the reservation data transmission process executed by the host computer 2 will be described. Host computer 2
Determines in S21 whether or not the reservation data transmission request signal transmitted via the communication artificial satellite 10 has been received. When the reservation data transmission request signal is received, the process proceeds to S22, and the vehicle number of the tank truck 3 and the fact that the reservation data transmission request signal is received are registered.

Subsequently, the reservation data corresponding to the vehicle number is retrieved from the reservation file 2a (S23). When the reservation data of the vehicle number is recorded in the reservation file 2a, the process proceeds to S24, and the reservation data corresponding to the vehicle number is sent to the communication satellite 10 as the next delivery scheduled data together with the vehicle number. Send.

On the other hand, the control circuit 16 of the vehicle-mounted terminal device 4 is
When the reservation data corresponding to the vehicle number transmitted via the communication artificial satellite 10 is received, the process proceeds from S2 to S3 and the reservation data corresponding to the vehicle number received is stored in a magnetic card (not shown). Remember. Subsequently, the received reservation data is displayed on the liquid crystal display 15 of the vehicle-mounted terminal device 4. As a result, the driver of the tank truck 3 can confirm the delivery destination (customer name), the oil type, the quantity, and the like to be loaded next time on the liquid crystal display 15.

Next, when the driver turns on the hatch allocation switch (not shown) of the vehicle-mounted terminal device 4 (S
5) A hatch allocation process is executed based on the reservation data (oil type and quantity data ordered by the customer) (S6). Then, the type of oil to be loaded and the loading amount are assigned to each hatch so that the gas purging work becomes unnecessary according to the type and amount of the previously loaded oil, and the printer 1
A slip in which the hatch allocation result is printed is issued from 1 (S7). This voucher contains 5 oil tanks near the next delivery destination.
Is designated and, for example, if the next delivery destination is in the area B, the driver goes to the oil tank location 5 ₂ in the area B instead of the oil tank location 5 _{1 in} which the normal oil liquid is loaded. Therefore, each hatch of the tank lorry vehicle 3 of the tank 20, the hydraulic fluid in the delivery schedule next time in the oil depots 5 ₂ is loaded.

When the driver of the tank truck 3 arrives at the oil tank station 5, as described above, the driver goes straight to the shipping stage 17 without depending on the office. Then, the magnetic card is ejected from the storage device 13 of the vehicle-mounted terminal device 4, and the shipping stage 1
7 is inserted into the card reader 19. When the vehicle number of the tank truck 3 for loading the oil liquid is input from the card reader 19, the shipping control device 6 permits the oil liquid to be shipped to the vehicle number read by the card reader 19.

When the magnetic card is ejected from the storage device 13, the control circuit 16 of the vehicle-mounted terminal device 4 recognizes that the tank truck 3 has arrived at the oil tank station 5 (S).
8). Then, at the shipping stage 17, the tank 20
When the oil liquid of the reservation data assigned to each hatch is loaded, the magnetic card is attached to the storage device 13. Therefore, when the magnetic card is attached to the storage device 13, it is determined that all the reserved oil types have been loaded (S
9) The oil type and quantity of the reservation data are registered as loading data (S10).

After that, the driver of the tank truck 3 departs from the oil tank station 5 and heads for the delivery gas station. When the tank truck 3 arrives at the delivery point of the delivery station and the unloading of the oil liquid is completed, the data such as the hatch, the type of oil, and the quantity of the unloading at this filling station can be obtained by the driver's key operation. It is stored in the magnetic card as the unloading data (S1
1). Next, it is determined whether or not all the oil liquid loaded in the tank truck 3 has been unloaded, and if the unloaded oil liquid remains in the hatch, the process returns to S11 and the next gas station Store the hatch, oil type, and quantity unloaded in the magnetic card. Then, when all the oil liquid loaded in the tank truck 3 is unloaded, S1 is again set.
Return to

As described above, after making a transmission request for reservation data in S1, if there is reservation data corresponding to the vehicle number of the tank truck 2 in the reservation file 2a of the host computer 2 in S2, the above S3 and subsequent steps are performed. The process of is executed again. However, if there is no reservation data corresponding to the vehicle number of the tank lorry vehicle 2 in the reservation file 2a of the host computer 2 in S2, the in-vehicle terminal device 4 moves to S13 and the delivery work of the day is completed.
Is displayed on the liquid crystal display 15. Therefore, the driver sees the display on the liquid crystal display 15 and confirms that there is no delivery schedule for the day, and finishes the delivery operation.

In this way, since the vehicle-mounted terminal device 4 equipped with the tank truck 3 can directly exchange data with the host computer 2 of the order receiving center 1, delivery is carried out from a plurality of oil tank stations 5 _{1 to} 5 _n. It becomes possible to use a plurality of oil tank stations 5 _{1 to} 5 _n by designating the oil tank station 5 near the front. Therefore, the delivery efficiency by the tank truck 3 can be improved, the round trip time with the oil tank place 5 can be shortened, and the unloading work at the delivery destination can be started earlier, and the oil liquid is ordered. The waiting time for customers can be greatly reduced.

Further, it becomes possible for the vehicle-mounted terminal device 4 to create the hatch allocation based on the reservation data transmitted from the host computer 2 before it arrives at the oil tank station 5, and it is troublesome to go to the office of the oil tank station 5. Is unnecessary and
The waiting time until the hatch allocation slip is issued becomes zero, and the oil liquid loading at the oil tank location 5 can be started earlier.

Further, at the oil tank station 5, since the hatch allocation process is unnecessary, the hatch setter and its operator, which have been conventionally installed in an office or the like, become unnecessary, and the cost can be reduced. In the above embodiment, the vehicle-mounted terminal device 4 of the tank truck 3 can communicate with the host computer 2 by satellite communication using the communication artificial satellite 10. However, the present invention is not limited to this. Of course, the reservation data may be transmitted and received.

In the above-described embodiment, the reservation data is transmitted from the host computer 2 to the tank truck 3.
