Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for displaying the operating status of a weighing machine at a gas station, and particularly for a fueling data processing system in which fueling data from a plurality of weighing machines is processed centrally. The present invention relates to an operating state display control device for a weighing machine at a gas station.

In a system like the one mentioned above, where refueling data from multiple weighing machines is processed centrally, it is necessary to know the operating status of each weighing machine in detail, for example, at a service station (hereinafter referred to as SS) at a gas station. There is. For this reason, for example, a refueling completion lamp could be provided for each weighing machine, and when refueling is complete, the corresponding lamp would blink to notify the SS operator that there is refueling data that needs to be processed. However, in such a method,
The disadvantage was that it was not possible to know the operating status of each weighing machine in detail.

Therefore, the main object of the present invention is to provide a control device for displaying the operation status of weighing machines at a gas filling station, which eliminates the above-mentioned drawbacks and allows detailed information on the operating status of each weighing machine. be.

In summary, the present invention provides a storage means for storing unprocessed refueling data for a plurality of times for each weighing machine, and stores the number of unprocessed refueling data or the number of empty areas stored in this storage means in the weighing machine. The processing status of the refueling data of each weighing machine can be displayed in detail by counting the results at each weighing machine and displaying the counting results numerically on the display. Further, the present invention allows the display mode of the display unit to be changed to normal display, reverse display, and forward/reverse display depending on the operating state of each weighing machine: before refueling, during refueling, and when refueling is completed. By controlling the alternating display to be switched to a predetermined one, the operating state of each weighing machine is indicated by the display state of the display.

The present invention will be specifically described with reference to the drawings shown below.

FIG. 1 is a schematic block diagram showing one embodiment of the present invention. In the configuration, a plurality of weighing machines 1-1
6 is connected to the CPU 18 via the weighing machine control section 17. Further, the CPU 18 is connected to a keyboard 19 and a display 20. Furthermore, CPU18
is connected to ROM21 and RAM22. This ROM 21 stores an operating program as shown in FIG. 5, for example. Also, RAM22
includes storage areas as shown in FIGS. 3a and 3b, for example.

FIG. 2 is a diagram showing an operation panel used in the embodiment of FIG. 1. This operation panel 23 includes a keyboard 19 and a display 20 shown in FIG. The keyboard 19 includes a product key 24, a numerical key 25, a function key 26, and a refueling enable command key (refueling start command means) 27. The product key 24 is used to input a product code. Usually, in such a device, product data (for example, unit price data, etc.) regarding multiple types of products (for example, regular gasoline, high-octane gasoline, diesel oil, or other products) correspond to each product key 24, that is, each product code. The product data is preset, and by operating the product key 24, the corresponding product data is read out. Numerical keys 25 are used to input various numerical data, such as the sales amount of fuel. The function keys 26 include, for example, keys for instructing the CPU 18 to perform various calculations. The refueling enable command key 27 is a key for instructing the start of refueling for each weighing machine, and corresponds to at least the weighing machines 1 to 16 shown in FIG.
Contains 16 keys. The display 20 is a numerical display 28
and an operating status indicator 29. Numerical display 28
For example, it is used to display amounts of money numerically. The operating status display 29 is one of the most important features of the present invention, and corresponds to at least each of the weighing machines 1 to 16 shown in FIG.
Contains 16 displays. Each display section is configured to be capable of displaying dots using a dot display, and displays the progress status of the corresponding weighing machines 1 to 16.

Figure 3 a and b are the RAM 22 in Figure 1.
FIG. 2 is a diagram showing storage areas of. As shown in FIG. 3a, the RAM 22 includes at least 16 refueling data storage areas corresponding to the weighing machines 1-16. In addition, in this embodiment, each refueling data storage area has 3
It is configured to be able to store refueling data for each batch. In addition, as shown in FIG. 3b, the RAM 22
includes raw data counters corresponding to the 16 refueling data storage areas shown in FIG. 3a. In addition,
The unprocessed lubrication data herein means, for example, data that has not been read out and printed or data that has not been stored in another data file. If this unprocessed refueling data is cleared, for example, by writing new refueling data, the above-mentioned processing will no longer be possible. Therefore, in this embodiment, the unprocessed data counter is used to count the number of unprocessed data stored in the corresponding refueling data storage area, thereby making it possible to determine how many more data can be written.

Figure 4 shows the operating status of the weighing machine and the operating status indicator 2.
9 is a diagram showing the relationship between the display states of the respective display sections constituting the display unit 9. FIG. As is clear from FIG.
There are two states. That is, there are a normal display state, a forward/reverse alternating display state, and a reverse display state. here,
The normal display state is a state in which only the dots of the character portion to be displayed are displayed. Further, the reverse display state refers to a state in which background dots other than the character portion to be displayed are displayed. That is, the character portion to be displayed is displayed in white. Further, the forward and reverse alternate display state refers to a state in which a character is displayed by alternately repeating the above-mentioned normal display and reverse display. As will be described in detail later, this display section displays the count number of the corresponding unprocessed data counter shown in FIG. 3b.

FIG. 5 is a flowchart for explaining the operation of the CPU 18 shown in FIG. Below, with reference to FIGS. 4 and 5, FIGS.
The operation of the illustrated embodiment will be explained.

First, as shown in Fig. 4, the display section is in the normal display state in the initial state, but since the count number of the unprocessed data counter shown in Fig. 3b is 0, no numbers are displayed. do not. Next, when the refueling nozzle is removed from the weighing machine, the CPU 18 detects this and switches the display state of the display unit to a forward/reverse alternating display state. Next, the operator recognizes that the refueling nozzle has been removed because the display is in an alternating forward and reverse display state, and also recognizes that the refueling nozzle has been removed by reading the numbers displayed (initial state, no numbers are displayed). When it is recognized that refueling is possible, a refueling start command is input by operating the corresponding refueling enable command key 27. In this embodiment, refueling is possible only when the number displayed on the display is 2 or less, and this is for the following reason. In other words, as mentioned above, the count number of the corresponding unprocessed data counter is displayed on the display, but this unprocessed data counter shows the unprocessed refueling data stored in the storage area in addition to the corresponding refueling data. Memorize the number of things. By the way, in this embodiment, each refueling data storage area is configured to be able to store three refueling data, so there are three unprocessed data.
In this case, when new refueling data is written due to refueling, the unprocessed refueling data will be cleared. Therefore, refueling is possible only when the number displayed on the display section is 2 or less, that is, the unprocessed data in the corresponding refueling data storage area is 2 or less.

When the CPU 18 detects that there is a refueling permission command, it turns on the refueling motor. Then, the corresponding display section is switched to the reverse display state. Next, when the CPU 18 detects the completion of refueling, for example due to the refueling nozzle being attached to the weighing machine, it turns off the refueling motor. Further, the CPU 18 reads the refueling data from the weighing machine and stores it in the corresponding refueling data storage area. At this time, the count number of the corresponding unprocessed data counter is incremented by one. And CPU18
switches the display section to normal display and displays the count number of the corresponding unprocessed data counter.

As shown in FIG. 4, the above-described operation is repeated every time fuel is supplied. By the way, although not shown in the flowchart of FIG. 5, each time the refueling data stored in the refueling data storage area is processed, the count number of the corresponding unprocessed data counter is -1 as shown in FIG. be done. Such a processing operation may be automatically performed by the CPU 18 as an interrupt process, or may be performed manually at the discretion of the operator.

In addition, in the embodiments shown in FIGS. 1 to 5, the third
Although the unprocessed data counter shown in Figure b is configured to store the number of unprocessed data in the corresponding refueling data storage area, it may instead store the number of data that has already been processed. . In this case, in the initial state, the display section displays 3, and refueling is not possible only when no number is displayed.

Furthermore, as shown in Figure 4, the display section can be switched to three display states depending on the operating state of the corresponding weighing machine, but each display state is uniquely determined by the operation of the weighing machine. isn't it. For example, the display may be displayed in the normal direction or in reverse when the refueling is not started, the normal display or the forward and reverse display may be displayed alternately during the refueling state, and the forward and reverse display may be displayed alternately when the refueling is completed. Alternatively, it may be displayed in reverse.

The embodiments of FIGS. 1 to 5 are as described above.
The number of unprocessed lubrication data is displayed on the corresponding display section in different display modes for the state before the start of lubrication, the state during lubrication, and the completion state of lubrication in the weighing machine, so that the operation of each weighing machine can be easily monitored. You can see the progress in great detail.

As described above, according to the present invention, since the number of unprocessed refueling data or the number of empty areas of each weighing machine is displayed numerically on each display part of the display,
The staff member can know in detail the processing status of refueling data of each weighing machine from the displayed numbers, and can clearly understand whether or not each weighing machine can be used. Further, according to the present invention, since the display mode of each display section of the display device is switched and controlled according to the operating state of each weighing machine, the staff can control the operation of each weighing machine from the display mode of each display section. The status can be clearly known and prompt processing and services can be performed based on it.

The advantage is that the staff can instantly grasp both the processing status of refueling data and the operating status of each weighing machine from the numerical display and display mode just by looking at each display section.
