Abstract

PURPOSE:To make an oil delivery control system applicable for both lorry and drumcan, by dividing an oil delivery port into two for a lorry and a drum can and by judging a finished load with a quantitative volume whether it is for lorry or drumcan. CONSTITUTION:When a signal 8b of completed loading, showing a port concerned, is input from LSC 8, it is calculated from which port the signal is transmitted. Loading ports and correspondence to lorries or drum cans are defined in advance in a reference table 9A of loading port/delivery means and the territory of the port concerned is referred. The port concerned is judged from the contents of the territory thereof as to whether it is for lorries or drumcans. When the judged result is for lorries, a loading volume externally set is read into a flowing volume oscillator 2 concerned and the read set-volume is subtracted from a reserved volume as a loading volume. On the other hand, the volume of one drumcan registered previously within the inside of the calculater is subtracted from the reserved volume as a loading volume. In the case of loading of drumcans, the loading volume is accurately controlled too.

Description

[Detailed description of the invention] [Industrial application field]

This invention can be applied to, for example, oil refineries or oil depots.
The present invention relates to a system that uses a computer to manage the shipping of fluids such as petroleum, and particularly to a fluid shipping management system that can automatically manage shipping according to fluid delivery means such as lorries and drums.

[Conventional technology]

FIG. 1 is a block diagram showing the configuration of an oil shipping management system as an embodiment of the present invention. Hereinafter, the conventional technology will be explained using this diagram. Note that the conventional system does not have a port/delivery means comparison table 9A in the management computer 9. In the figure, reference numeral 5 (58 to 5C) is a start button provided for each oil loading port and oil type, and is an operation switch for instructing the start of carrying out the oil of the oil type. 4 (4
A to 4C) are tanks for each type of oil, and 3 (3A to 3C) are pumps for each tank 4A to 4C, and this pump 3 pumps out the oil from the corresponding tank 4 and sends it to the flow rate transmitter 2 described below. send to the side 2 (2A to 2C) are flow rate transmitters provided corresponding to the start buttons 5^ to 5C, respectively, and the quantity of oil (normally 1 kJ!,
A cam pulse CP is output every time 2kft or 4kl (either 2kft or 4kl can be selected) passes. 1 (1Δ~IC) are valves provided corresponding to the flow rate transmitters 2A to 2C, respectively, and receive valve opening/closing signals 8 from a fixed quantity shipping control device (hereinafter also abbreviated as LSC) 8, which will be described later.
a, and opens and closes the relevant petroleum export port. 6 is the delivery vehicle number corresponding to the ID code of the customer. 7 is a means of oil delivery such as a lorry or a drum (loading truck); 9 is a management computer (hereinafter also abbreviated as LSM)
Then, from the CRT operator console 10 etc., the delivery vehicle Nα
In addition to manually storing another oil reservation amount, inputting each output signal of the card reader 6, start button 5, loading completion signal 8b from the quantitative shipping device 8, etc., and giving a shipping instruction for the oil to the LSC 8. Performs oil shipping management such as collecting shipments and calculating shipment volumes. LSC8 selects the corresponding valve 1 based on the command of LSM9.
A valve opening/closing signal 8a for opening is given to the corresponding valve 1, and a valve opening/closing signal 8a for closing is given to the corresponding valve 1 based on the cam pulse CP from the corresponding flow rate transmitter 2. Further, at the same time as this loading is completed, a loading completion signal 8b indicating the loading in question is given to the LSM 9, and a set value of the loading amount set in the external setting device of the relevant flow rate transmitter 2 is given. Note that 10 is LS
CR,T operator console for C8 and LSM9. Next, the conventional operation shown in FIG. 1 will be explained. The driver of the oil delivery means 7, such as a lorry, inserts the delivery vehicle Nα card corresponding to him into the card reader 6, and presses the start button 5 of the target oil type on the load of the oil delivery means 7. The management computer (LSM) 9 receives the delivery vehicle number from the card reader 6,
and perform checks such as reservation verification. If the check result is good, the quantitative shipping controller (LSC) 8 is notified accordingly. The LSC8 receives the check good signal from the LSM9 and outputs a valve opening/closing signal 8a to the corresponding valve 1. As a result, the relevant oil starts to be carried out from the relevant valve 1 to the oil delivery means °7, and when the flow rate set externally to the corresponding flow rate transmitter 2 is completed, a cam pulse is sent from this flow rate transmitter 2 to L S C8. CP is sent, and as a result, the LSC8 outputs a close valve opening/closing signal 8a to the relevant valve 1, sends a loading completion signal 8b indicating the relevant loading to the LSM9, and further outputs the relevant loading setting value. send. This allows the LSM 9 to know that loading of the set amount has been completed normally. These operations are repeated until all reserved amounts of the oil type have been loaded. Normally, lorries can carry several types of oil, so reservations are pre-registered for several types of oil. Therefore, the driver of the oil delivery vehicle 7 repeats the same operation for all types of oil. When all the oil to be loaded on the delivery vehicle has been successfully shipped, the delivery vehicle number and card will be unlocked, and the delivery vehicle driver will be allowed to leave the loading dock and deliver oil to each customer. In the case of a 60-car vehicle, the setting value on the external setting device is 1 to 1 depending on the size of the loading hatch. 2 to 1. 4kl
You can choose from three types. For example, when the external setting device is set to a set value of 1 kl, the flow rate transmitter 2 sends one cam pulse 2a to the LSC 8 when loading of 1 kl is completed. In response to this pulse signal 2a, the LSC 8 outputs a valve opening/closing signal 8a to close the valve 1, and further issues a loading completion signal 8b to the LSM 9 to indicate that loading of 1 kl has been completed in the relevant loading. Notice. If the set value is 2 farts, set the external setting device to 2 farts, and the flow rate transmitter 2 will output 2 farts.
When loading of d is completed, cam pulse 2a is fired once, LS

A loading completion signal 8b etc. is issued to 9, and with this loading 2k
It is notified that the loading of 1 is completed. The setting plant is 4kl
The same applies to the case of .

[Image problem to be solved by the invention]

When this type of oil shipping control device is applied to loading drums, there are the following problems. The set amount for one fixed loading is usually Lkl, 2kL4
Since only three types of kl can be selected, even if the internal setting of the flow rate transmitter is changed and loading of one drum (normally 200f) is completed, the end will be either the end of 1, kl or the end of 2 kl. The LSC8 cannot notify the LSM9 other than as the end of the 4kl or the end of the 4kl. That is, by changing the internal setting of the flow rate transmitter 2, the external setting value 1 is changed.
200 at kl! When loading drums by weighing and outputting cam pulses CP, LSC8 loads 1d for LSM9 even though 2001 loadings for one drum have actually been completed. As a result, the LSM9 cannot perform accurate management. Therefore, in order to solve this problem, the present invention divides the loading port into one for tank cars as a fluid delivery means and one for drum cans, and internally sets the flow rate of the flow rate transmitter 2 of the loading port for drums at 200 degrees Celsius. , a table is provided in the management computer 9 that can compare loading ports and fluid delivery means, and when one fixed-quantity loading is completed, if it is loading into a lorry, an external setting device is usually set. The loading set amount set in the flow rate transmitter 2 is managed to be subtracted from the reserved amount via the It is an object of the present invention to provide a flow rate shipping management system that manages the capacity of one drum set in a management computer so as to subtract it from the reserved quantity, regardless of the set quantity.

[Means to solve the problem]

In order to solve the above-mentioned problems, the system of the present invention has "fluid loading ports classified by type of fluid delivery means (oil delivery means 7, etc.) such as lorries and drums, and a fluid loading port provided for each loading port. Switch for specifying fluid type (
(start button 5, etc.), and based on the operation of the switch, the fluid of the relevant type is delivered to the loading port in a preset amount according to the type of the fluid delivery means corresponding to this loading port. Fixed amount delivery means (valve 1, flow rate transmitter 2, fixed amount shipping device 8) that outputs at least a loading completion signal (8b, etc.) indicating the loading port in question.
etc.) 7. A system for managing fluid shipment by inputting at least data identifying the customer (via card league 6 etc.) and the loading signal, the system comprising: Storage means (loading port/
(a delivery means comparison table 9A, etc.); and a means (such as a management computer 9) for referring to the storage means based on the loading completion signal and totalizing the amount of the corresponding fluid to be delivered. do.

[For use]

It is determined whether the completed fixed-quantity loading is for a lorry or a drum, so in the case of a lorry, the loading setting amount on the external setting device is subtracted from the reserved amount, and in the case of a drum, the calculator stores it internally. The capacity of one drum can can be subtracted from the reserved amount, and even when loading drums, the loading amount can be accurately managed.

【Example】

The present invention will be described in detail below with reference to FIGS. 1 to 3. Due to the nature of the loading equipment in the oil land shipping system,
The loading port for loading lorries and the loading port for loading drums have different shapes, and it is not possible to load both lorries and drums from the same loading port. Therefore, in the present invention, as shown in FIG. 1, the oil loading port is divided into dedicated loading ports according to the types of lorries and drums serving as the loading port delivery means 7, and the start button 5, the corresponding flow rate oscillator 2 and the valve 1 also corresponds to the type of oil delivery means 7, respectively. The loading weight values of the flow rate oscillator 2 at the loading port of the lorry are Lkl, 2kl, and 2kl as before.
Three types of 4kl are set via an external setting device, but the loading measurement value of the flow rate oscillator 2 at the loading port of the drum is internally set to 2001 regardless of the setting value of the external setting device. The management computer (LSM) 9 stores a loading port/delivery means comparison table 9A for comparing loading ports and whether they are for lorries or drums. do. 2 is a flowchart showing an overview of the processing procedure of the LSM 9 shown in FIG. 1, and FIG. 3 is a flowchart showing the detailed procedure of steps (1) to (2) in FIG. Next, FIGS. 2 and 3 will be explained with reference to FIG. 1. In FIG. 2, first, in step (2), a lorry or a truck loaded with drums serving as the oil delivery means 7 stops at a loading port determined according to the type of delivery means 7, and an operator uses a card reader to load oil. Insert the delivery vehicle Nα card into 6. In step (2), the operator presses the start button 5 provided at this loading port and corresponding to the type of oil to be loaded. In step (2), the LSM 9 checks whether or not there is a reservation for the oil type for the oil delivery means 7 in question, and if there is a reservation, the process proceeds to step (2), and if there is no reservation, an error process is performed. In step (2), a command to open the valve 1 corresponding to the pressed start switch 5 of the loading port is output to the LSC 8, and in step (2), quantitative loading of the oil type in question is started via the LSC8. In step (2), wait until quantitative loading is completed. When the quantitative loading is completed, the process proceeds to step (3), where it is determined whether the completed quantitative loading is for a lorry or for a drum can, as described in the detailed procedure of FIG. As a result of this determination, if the loading is for a lorry vehicle, proceed to step ■.
The loading setting amount (Ik
l, 2&i. 4kl) is subtracted from the reserved amount as the loading amount. If the determination result in step (2) is that drum cans are to be loaded, the process proceeds to step (2), and regardless of the external setting value of the flow rate oscillator 2, the drum can 1 registered in advance in the LSMB is loaded.
The capacity of the can (200ffi) is subtracted from the reserved amount as the loading amount. Next, in the case of loading either lorries or drum cans, the process proceeds to step [phase], where it is determined whether loading has been completed for all of the reserved amount. If the loading of all reservations has not been completed, the process returns to step (2) and the operator presses the start button 5 corresponding to the oil to be loaded for the next loading. If the entire reserved amount has been loaded, proceed to step ■ and transfer to delivery vehicle N.
The α card is unlocked and this processing procedure ends. Here, what is different from the conventional method is the determination means in step (2) and the calculation means in step (2). This point will be explained in more detail with reference to FIG. In this embodiment, a method of determination is shown using the port/delivery means comparison table 9A. That is, when the loading completion signal 8b indicating the loading port (number) in question is inputted from the LSC 8 at step (2) in FIG. 2, it is calculated which loading port the signal is from (step (2)-1). The area of the loading port is referred to in the loading port/delivery means comparison table 9 in which the correspondence between the loading port and whether it is for lorries or drums is defined in advance (step 2-2). Based on the contents of the area of the loading port, it is determined whether the loading port is for lorries or drums (step ①-3). If the result of this determination is that it is a lorry vehicle, proceed to step (2), and if the determination result is that it is a drum can, proceed to step (2). In step (2), the loading set amount externally set in the relevant flow rate oscillator 2 is read from the LSC 8 (step (2)-1), and the read set amount is subtracted from the reserved amount as the loading amount (2). On the other hand, in step (2), the capacity for one drum (2001), which is registered in advance in the computer, is subtracted from the reserved amount as the loading amount. Both step ■ and step ■ proceed to step [phase].

【Effect of the invention】

According to the present invention, in the oil shipping management system, the oil loading ports are divided into those for lorries and those for drums, and a means is provided for determining whether the completed fixed-quantity loading is for lorries or drums. It is also possible to accurately manage the loading amount for drums, and it is possible to construct an oil shipping management system that can be applied to both lorries and drums.
