Reference numeral 26 denotes a logging memory board, which is provided, for example, below the stage 11 and stores a message of a work executed by the shipping control device 5 as described later. The shipping control device 5 is connected to a host computer 27 via a communication line 28, and sends and receives data via the communication line 28. A terminal device 29 is connected to the host computer 27, and includes a display 30 for displaying a message, a printer 31, and an auxiliary storage device 32 for storing a message of the executed shipping operation on a recording medium such as a magnetic disk as described later. Have. Here, the processing executed by the shipping control device 5 when the fixed quantity of the oil liquid is shipped to the tank truck 3 will be described with reference to FIG. First, when the tank truck 3 arrives at the shipping bay A of the stage 11, a shipping worker at the site attaches the grounding device 24 to the body of the tank truck 3. Next, the setting switch 16a of the setting device 16 is operated to set the loading amount to be shipped to the tank 4 of the tank truck 3. The shipping request data is input by the setting operation of the loading amount (step S1), and it is confirmed that there is an oil type suitable for the shipping bay A set and operated (step S2). Further, the host computer 27 collates the setting data with the reservation data, and if there is the corresponding reservation data, a signal of data collation OK is input (Step S).
3) Output a signal indicating that shipment is OK at the corresponding shipment points 2a to 2d (step S4). In addition, when the data of the shipment request is not input in Step 1, when there is no compatible oil type in the corresponding shipping bay in Step S2, and when the data collation OK signal is not output in Step S3, each other process is executed. . In step S4, when a shipping OK signal is output,
The lamp of the display 17 is turned on to indicate a shippable point among the shipping points 2a to 2d. Then, the site worker inserts the loading arm 12 at the designated shipping point into the hatch filler ports 13a to 13c of the tank truck 3. And the hatch cards 14a to 14c of the hatches 4a to 4c are card readers.
When inserted into 15, read the hatch capacity data. When the lamp of the display 17 is turned on, it is confirmed from the status signal from the earthing device 24 that the earthing device 24 is connected to the tank truck 3 in step S5. In step S5, when the ground signal indicates that the status signal is in the ground connection state, the start switch of the setting device 16 is turned on.
16b is depressed, a start signal is supplied, and fixed quantity shipping control of the set oil liquid is performed (step S6). That is,
When the start signal is supplied, a valve opening signal is output to the fixed quantity valve 23 to start shipping, and when the loaded amount reaches the hatch capacity, the fixed quantity valve 23 is closed. In step S7, the completion of the reserved loading amount in the corresponding shipping bay A in which shipping work is being performed during the above-mentioned fixed quantity shipping control is confirmed. If the reserved loading amount has not yet been loaded in step S7, the process returns to step S5 and checks the status signal from the grounding device 24 again. If the ground signal is ON, quantitative shipping control is performed as it is, and step S5
Repeat ~ S7. This is to monitor that a part of the reserved loading amount is left unloaded after the start of the shipment so that no unloading occurs. In this way, when repeatedly executing steps S5 to S7, for example, if the reserved loading amount is 4 kl, the 4 kl oil liquid is hatched.
When all of the items have been loaded into 4a, it is determined in step S7 that the loading of the reservation has been completed, and the monitoring of the unloading is released (step S8). However, it is assumed that, although a reserved loading amount of 4 kl is set, the fixed quantity shipment is urgently stopped when loading is performed up to 3 kl. After a while, when the emergency stop is released,
An operator may forget that there is still 1 kl of unloaded material and remove the grounding device 24. Or, for example, 6kl
If there is a reserved loading amount, after loading 4 kl of oil liquid on the hatch 4 a, without loading the remaining 2 kl on the hatch 4 b,
4 may be removed. In such a case, since the reserved amount has not been loaded in step S7, the status signal of the grounding device 24 is output in step S5.
Signal OF indicating that has been removed from tank truck 3
It becomes F, and it is determined that there is a backlog. In step S5, when the ground signal is OFF, an alarm signal for notifying the alarm 18 of the abnormality due to the unloading is output (step S5).
9). The site worker who knew that there was unloading by the alarm of the alarm 18 did not interrupt the loading operation (step S10).
The grounding device 24 is connected to the tank truck 3 again, and when the ground signal ON is obtained, the alarm is released (step S12). When the grounding device 24 is still removed in step S11, the processes in steps S9 to S11 are repeated,
The alarm will be issued until the shipping work is resumed. As described above, since the loading of the reserved amount in the shipping bay is always monitored during the fixed quantity shipping control, it is possible to prevent the unloading from occurring in the shipping bay. Further, an alarm is issued when the grounding device 24 is removed from the vehicle body during loading of the reserved amount, so that it is possible to prevent the tank truck 3 from leaving the vehicle with unloaded. In the above description, it is assumed that an alarm is issued from the alarm device 18 when the grounding device 24 is removed when there is an unloading, but a lamp for indicating the unloading may be provided, and this lamp may blink together with the alarm. good. In addition, the shipping control device 5 has a work procedure (for example, an input from the card reader 15, a status signal from the grounding device 24, a signal from the setting switch 16a and the start switch 16b, an emergency stop signal, etc.) executed at the time of the fixed quantity shipping. There is provided a logging function for creating a logging file that records the above message. Here, the logging function will be described with reference to FIGS. First, in FIG. 5, when a request to print a message of the processed work procedure is issued from a task, which is one control program of the shipping control, for example (step S21), the message is converted into a print format for printing and recorded. Preparation for storage in a medium is performed (step S22). Next, a message of the print format is recorded on a magnetic disk or the like of the auxiliary storage device 32 of the terminal device 29 (step S2).
3). Further, since the message of the operation of the fixed quantity shipping control is recorded in the logging file created in the auxiliary storage device 32 as described above, the message can be viewed when necessary. That is, when the user wants to know the message of the logging file, the terminal device 29 is operated to make a message output request. If there is a message output request (step S2
5) It is confirmed whether the message is displayed on the display 30 or printed out by the printer 31 (step S26). If the printer 31 is specified in step S26, the message of the logging file is printed by the printer 31 (step S27), and if the display 30 is specified, the message is displayed on the screen of the display 30 (step S28). Therefore, the logging file can be semi-permanently stored in the auxiliary storage device 32, so that the message can be easily viewed when the user wants to view the message, and can also be viewed in the message several days ago. In the above description, the logging file is stored in the auxiliary storage device.
Although described as being stored in the storage 32, the present invention is not limited to this. For example, a logging file of the work executed in the stage 11 may be stored in a logging memory board 26 provided below the stage 11. Also, the memory board 26
When viewing the logging file, the terminal device 29 is operated to supply a read command from the host computer 27 via the communication line 28. The messages in the logging file are displayed sequentially on the display 30 or
Printed out at 31. Therefore, for example, when an emergency stop occurs, the operation procedure of the on-site worker can be easily known, and recovery measures for the emergency stop can be easily taken. Further, since it is easy to grasp the restoration state of the emergency stop, it is possible to shorten the restoration time and improve safety. Effects of the Invention As described above, according to the present invention, it is detected by the ground detection means and the loading stop detection means that the tank truck is about to leave the shipping bay, and based on the detection result,
When the determining means determines that the loading amount to the tank lorry vehicle has not reached the reserved loading amount, in order to positively tend to the worker that all the oil liquid to be loaded to the tank lorry vehicle is not loaded. Since an alarm is issued by the alarm control means, it is possible to prevent a situation in which the oil liquor to be loaded in the tank lorry is not loaded and the vehicle leaves the shipping bay as it is.
