Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention uses a computer to manage the amount of fluid shipped from a storage tank that stores fluid such as petroleum at an oil refinery or oil depot. The present invention relates to a fluid shipment management device, and particularly relates to an improvement in forced trip termination processing performed when an abnormal state occurs in fluid shipment.

[Conventional technology]

As a conventional fluid shipping management device, one having a tank bottom as shown in FIG. 4 is known.

This system includes a cart reader 1 that reads and holds a lorry vehicle number cart c in which an identification code corresponding to the tank lorry owned by the driver of a tank lorry as a fluid transport vehicle is recorded in advance, and a cart reader 1 that reads and holds the lorry vehicle number cart c, which corresponds to the type of oil. A plurality of start buttons 28 to 2c are connected to the management computer 3,
This management computer 3 performs checks such as predetermined collation,
If the check result is OK, the quantitative shipping control device 4 is notified of this. Based on a command signal from the management computer 3, the fixed quantity shipping control device 4 controls tanks 58 to 5c for storing fluid, and pumps 6a to 5c connected to these tanks, respectively.
6c, flow rate transmitters 7a to 7c and on/off valves 88 to 8C
A predetermined amount of fluid is loaded into the tank truck 9 by controlling the fluid shipping system while monitoring the flow rate detection pulses from the flow rate transmitters 78 to 7C.

Next, the processing procedure for shipping operations will be explained with reference to FIG.

That is, the driver of the tank truck 9 inserts the truck number card C corresponding to his tank truck IJ 9 into the card reader 1 (step 2), and then presses the start button 2a to 2c corresponding to the desired oil type (for example, 2a,
) and press it (step ■). Management computer 3
reads the low-speed vehicle number recorded on the low-speed vehicle number card from the card reader 1, checks this against the reservation, etc., and if the check result is OK, the quantitative shipping control Notify device 4 (step ■).

Upon receiving this notification, the fixed quantity shipping control device 4 outputs a valve open signal to the on-off valve 8a corresponding to the desired oil type to open the on-off valve 8a (step 2).

In this way, when the on-off valve 8a is in the open state, the fluid from the fluid storage tank 5a is sent to the tank truck 9 by the pump 6a via the on-off valve 8a to start shipping. Flow rate detection pulses output for each flow rate are counted by the fixed quantity shipping control device 4 (step 2).

Then, the shipment is carried out in successive steps until the shipping flow rate, that is, the count value of the flow rate detection pulse, matches the setting value set at the site (usually 1, 2, 4 KA). When the two match, the valve is closed. A signal is output to the on-off valve 8a and the management computer 3, respectively, to stop the shipment of fluid (step 2).

By receiving the valve closing signal, the management computer 3
It is determined that the shipment of the set amount has been completed, and the number of fixed-quantity shipments of the corresponding oil type is counted up (step ■), and then it is determined whether the shipment of the reserved amount of all oil types has been completed (step ■). , when the shipment is incomplete,
Return to step (3) and repeat the above process for other oil types.

After that, when the reserved quantities of all the reserved shipping oil types are successfully completed, the lock status of the tank truck number card in the card reader 1 is released (step [phase]), and the tank truck driver leaves the loading dock. It becomes possible to leave,
The tank truck 9 is operated to start delivery to each customer.

Here, the tank truck 9 normally makes deliveries two to three times in one day. In other words, the oil loaded at the loading dock is delivered to each customer, and after the delivery is completed, the oil is returned to the loading dock again, loaded with oil, and delivered again. One cycle from loading to delivery at such a loading dock is called "one trip."

Therefore, one tank truck 9 makes two to three trips a day, and the amount of oil loaded differs for each trip. In other words, the reservation for the lorry car number recorded on the lorry car number card is divided into 2 to 3 trips, and each trip reservation is made up of several types of oil and their reserved oil quantities, and the management computer has been registered in advance.

In addition, the fixed quantity shipping control device 4 receives a valve open signal to open the on-off valves 8a to 8c, counts the flow rate detection pulses of the flow rate transmitters 7a to 7c until the set value set at the site is reached, and calculates the set value. The period from when the valve closes to the point where the valve close signal is output is called "one batch".If for some reason oil is not shipped normally during one batch,
The fixed quantity shipping control device 4 resets the flow rate detection pulse count that had been counting halfway, so that the batch in this factory can be manually terminated, and this is called batch reset.

Furthermore, once the lorry car number card C is inserted into the card reader 1, the lorry car number card C is locked so that it cannot be removed until the shipping of all oil types in one trip is completed normally. However, if some abnormality occurs in the fluid shipping system and it is impossible to successfully complete all shipments of a trip, the trip can be terminated by operating the function key for forced trip termination located on the operator console. It can be forcibly terminated.

Normally, the batch reset and forced trip termination functions are as follows:
Used as follows: Now consider a tank truck in which each trip is booked as shown in FIG. Assuming that the tank truck enters the loading dock for the second shipment of birds and bu, first, in order to ship oil type A, the loading port setting for oil type A is set to 4KN. Press the start button. As a result, shipment of oil type A is started, but it is assumed that in this shipping state, an emergency stop state occurs due to some factor, and shipping is stopped. In this case, if the cause of the emergency stop is removed, shipping will continue normally by pressing the start button again. However, if the cause of the emergency stop cannot be removed, perform a hatch reset to correct the problem. Assume that the patch is finished.

At this time, the reservation for the oil type is 6KE from Figure 6, so there is one in two remaining quantity to be shipped. Since there is no control over whether the remaining 2Kl has been shipped, the total will not be 6Kff even if the remaining 2Kl is shipped normally). If the remaining 2 to 4 cannot be shipped normally, the shipment of the B oil type is suspended and the next B oil type is shipped.

Continue to ship C oil type. After that, when all trip shipments are completed except for oil type A, press the trip forced termination function key to force trip termination.
The lock state of the lorry vehicle number card is released, the lorry vehicle number card is taken out from the card reader 1, and the tank truck leaves the loading dock and goes out for delivery.

[Problem that the invention seeks to solve]

However, in the conventional fluid shipping management device described above, there are no restrictions when the trip forced termination function is activated, so for example, as shown in FIG. This time, the shipment of A oil type and B oil type was completed normally, but an abnormal condition occurred during the last patch of the C oil type, resulting in an emergency stop. It is assumed that

At this time, there is a problem in that it is not possible to prevent the low-road vehicle number card from being unlocked by only forcibly terminating the trip without performing a patch reset. In other words, if the trip is forcibly terminated without resetting the hatch, the value of the flow rate pulse counted up to the middle of the last punch will remain in the quantitative shipping control device 4 without being cleared, and in this state, if another tank load is When the start button is pressed from the loading port for oil type C, the flow rate pulse will not be counted up from zero, but will be added to the previous count value, so the shipping amount for this tank truck will be The amount shipped will be less than the set value, making it impossible to ship accurately.

Therefore, the present invention was made by focusing on the problems of the conventional device described above, and when there is a loading port that is in an emergency stop state during the hatch, the forced trip termination process is performed only after resetting the hatch. The purpose of the present invention is to provide a fluid shipping management device that can perform the following steps.

[Means for solving problems]

In order to achieve the above object, the present invention, as shown in the basic configuration diagram of FIG. Ship the fluid while monitoring the shipping status of 2.
a shipping control device that urgently stops fluid shipment when an abnormal shipping condition is detected; an instruction device that instructs forced termination of the trip; information display means for supplying and displaying patch reset request information on a display device when the stopped state continues; response determination means for determining whether there is a response to the bunch reset request; and response determination means. The present invention is characterized by comprising a trip forced termination means that executes trip forced termination processing only when the determination result of the means is that there is a response.

[Effect]

In this invention, the shipping state of the fluid in the fluid shipping system is monitored and controlled by the shipping control device, and when the shipping control device detects an abnormal shipping state, shipping is stopped, and then the trip is tripped by the trip forced termination instructing means. When a forced termination is instructed, the information display means sends hatch reset request information to the display device and displays it, and determines whether there is a response to batch reset such as pressing of a hatch reset button or the like corresponding to this hatch reset request information. The response determination means determines whether there is a response, and only when the determination result is that there is a response, the trip forcible termination means can forcefully terminate the trip.This prevents forgetting to execute a batch reset and ensures accuracy. It is possible to ensure safe shipping conditions.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 2 is a block diagram showing one embodiment of the present invention.

In the diagram, C is a low-speed car number card, 1 is a card reader, and 2a
~2c is a start button, 3 is a management computer, 4 is a quantitative shipping control device, 5a~5C and a fluid storage tank, 6a~6
C is a pump, 7a to 7C are flow rate transmitters, 88 to 8c are on-off valves, and 9 is a tanker, which are the same as the conventional example described above except for the trip forced termination processing procedure in the management computer 3. It has a configuration.

Therefore, CR is sent to the management computer 3 and fixed quantity shipping control device 4.
An operator console 12 with a T-display lO and a keyboard 11 is connected. Here, the keyboard 11 includes a trip forced termination function key 11a as a trip forced termination instructing means for instructing trip forced termination, a cancel key 11b for canceling the trip forced termination process, and a flow rate control unit 4 in the quantitative shipping control device 4. At least a batch reset key 110 for resetting the count value of flow rate detection pulses from the transmitters 7a to 7c is arranged.

Further, in this embodiment, the trip forced termination processing procedure of the management computer 3 is executed as an interrupt process by pressing the trip forced termination function key 118 or by scanning, as shown in FIG.

That is, first, in step (2), it is determined whether or not there is a loading dock for the corresponding tank truck 9 that is currently being shipped. In this case, the determination is made, for example, by the quantitative shipping control device 4 using the flow rate transmitter 7a.
It is determined whether or not the flow rate detection pulses from ~7c are being counted, and when the flow rate detection pulses are being counted, the process moves to step [phase] and message information indicating that shipping is in progress is output to the CRT display 10. and display it on the display screen.

On the other hand, if the determination result in step (■) is that there is no loading port currently being shipped, the process moves to step 0, and the process has not ended normally at the loading port that the management computer 3 has authorized for shipment to the loading dock of the corresponding tank truck. Determine whether something exists. In this case, the judgment is made by monitoring whether or not the shipment of the fluid stored in the memory of the fixed quantity shipment control device 4 is being carried out normally, and if the emergency shipment has been stopped due to the occurrence of an abnormal condition and this has not been recovered. This is done by reading the memory contents that indicate whether or not the state is present. Here, monitoring of the shipping state in the fixed quantity shipping control device 4 is carried out, for example, while a valve open signal is output to the on-off valves 8a to 8c, and a flow rate detection pulse from the flow rate transmitters 7a to 7C arrives within a predetermined time. Flow rate generation (iH7a to 7c are operating normally, opening/closing valves 8a to 8c are normally open, pumps 6a to 6c are operating normally, etc.) If the monitoring result indicates that an abnormal state has occurred during shipping and has not been recovered, the occurrence of the abnormal state is stored in the memory, and this is stored in the management computer 3.
The management computer 3 is notified by a command signal from.

If the judgment result in step 0 is that the shipping has been completed normally at the loading port where the management computer 3 has authorized shipping, the process moves to step The locked state of the low-speed car number card inserted in 1 is released to enable the low-speed car number card to be taken out.

In addition, if the judgment result in step @ is that there is a load that has ended in an abnormal state, the process moves to step ■ and the CRT
The loading dock number where the abnormality occurred and a batch reset request message are outputted to the display 10 and displayed on the display screen.

Next, the process moves to step [phase], and it is determined whether or not the hatch reset manual input for the corresponding loading port has been input by operating the para-recent button llc of the operator console 12. At this time, when there is a batch reset input, the process moves to step @ and the trip forced termination process is performed, and when there is no hatch reset input, the cancel key is pressed to move to step [phase] and cancel the trip forced termination process. 11b is pressed, and if the cancel key 11b is pressed, the process is terminated and the cancel key ILc is pressed.
When is not pressed, the process returns to step ■.

Here, the processing in steps [phase] and (2) corresponds to the information display means, the processing in steps (4) and [phase] corresponds to the response determination means, and the processing in step O corresponds to the trip forced termination means.

Next, the operation of the above embodiment will be explained.

Now, when the shipment of each oil type in one trip to the tank truck 9 has been completed normally, the function key 118 for forced trip termination is not pressed, so the management computer 3 Similarly, the fifth
The process shown in the figure is performed to perform normal shipping management.

When the trip forced termination function key 11a is accidentally pressed while fluid is being shipped to the tank truck 9, the management computer 3 executes the trip forced termination interrupt process shown in FIG. However, in this case, since the fluid is being shipped to the tank truck 9, the process moves from step ■ to step ■, and the CRT display 10
After displaying the shipping message on the display screen, the trip forced termination interrupt processing is terminated. Therefore, in this state, there is no transition to the trip forced termination process in step @, so it is possible to prevent the trip forced termination process from being performed due to an erroneous input.

In addition, if an abnormal condition occurs during one trip and the quantitative shipping control device 4 stores in its memory that there is a loading port that continues to be in an emergency shipment stop state, all When the shipping process is completed for the oil type, the lock state of the low-speed car number card in the card reader 1 is not released, so the operator presses the trip forced termination function key 11a.

Function key 11 for forced trip termination like this
When a is pressed, the process shown in Figure 3 starts to be executed, and since shipping for each oil type has been completed, step
Then, the process moves to step 0, and since there is a loading port that continues to be in an emergency shipment suspension state, it moves to step
It is output and displayed on the display 10.

Therefore, when the operator presses the hatch reset key 11c of the corresponding loading port to reset the contents of the counter that counts the flow rate detection pulses from the flow rate transmitters 7a to 7c of the quantitative shipping control device 4, steps Then, a trip forced termination process is performed to release the locked state of the low-speed car number card inserted into the card reader 1, and to make it possible to take out the low-speed car number card. Thereby, the driver can drive the tank truck 9 to deliver to the customer.

At this time, if the operator does not press the hatch reset key 11c, the process moves from step ■ to step [phase], determines whether or not the operator has pressed the cancel key 11b for canceling the trip forced termination process, and presses the cancel key 11b. If the button has been pressed, the process is immediately terminated, and if the cancel key 11b has not been pressed, the process returns to step (2) to repeat the process of determining whether or not the batch reset key 11c has been pressed. That is, in the state where the patch reset request message is displayed in step 2 after the trip forced termination function key 11a is pressed, either the patch reset process is performed or the trip forced termination interrupt process is canceled. Since the forced trip termination process is not executed unless the process is performed, it is possible to perform the forced trip termination process without performing a parallel center, and to reliably prevent under-weighing during the next shipment of the same contact point. can.

In the above embodiments, the case where the fluid is a petroleum product has been described, but the present invention is not limited to this, and the present invention can be applied to the shipping of any other fluid.

Further, in the above embodiment, a case has been described in which a plurality of types of oil are loaded onto the tank truck 9 through a plurality of ports, but it goes without saying that the present invention can also be applied to the case where one type of fluid is loaded onto a tank truck. be.

Further, in the above embodiment, the case where fluid is loaded onto the tank truck 9 has been described, but the present invention is not limited to this, and the present invention can also be applied to the case where fluid is loaded onto other transportation means such as a tanker or a tank truck. It's something you get.

Furthermore, in the above embodiment, a case has been described in which it is determined whether or not there is a batch reset input in step (3) in the trip forced termination process, but instead of this, it is determined whether or not the hatch reset process has ended. may be determined.

Further, the display device for displaying the bunch reset request is not limited to a CRT display, and other display devices such as a liquid crystal display device can be used.

〔Effect of the invention〕

As explained above, according to the present invention, when an emergency shipping stop state occurs in the shipping control device during fluid shipment and the trip forced termination process is performed, the shipping control device The batch reset request information for resetting the flow rate count value is displayed on the information display means, and the forced trip termination process can be performed only when a predetermined response is received, so there is no need to perform the batch reset process. It is possible to reliably prevent the trip forced termination process, and there is an effect that no error occurs in the flow rate detection value in the shipping control device (and accurate shipping management can be performed).
