When the creator starts the control table creation processing device 11 shown in FIG. 2 in order to create a control table To etc. corresponding to the seaverse foam monitoring process, the following information is displayed on the screen of the display 12. (A control table frame as shown in C1 is displayed.

In the frames shown in FIGS. 5(a) to (C), the type indicates which of the four types of processing shown in FIG. 7, namely control, judgment, delay, and function, and the tag number/function number is Indicates the code given to the controlled device/function, Condition/Control direction indicates the judgment condition/control direction of the controlled device, Set value/Judgment value indicates the value used for control/judgment, and Skip indicates the type. In the case of judgment, it indicates the presence or absence of a skip, the timer indicates the control/judgment monitoring time, and the end indicates that there is no next level processing.

In FIG. 5(al), when creating the control table TO for the seaverse foam monitoring process shown in FIG. In the title column of the control table frame, enter the function assigned to the seaverse foam monitor process = T002 and the function name = seaverse foam monitor process, and then enter the fire prevention seawater pump startup process P1 in the - column. Function number = TO51, level = 1, type = function (actually enter the code indicating the function),
Enter End = × manually, and then enter function number = TO52, level = 1, regarding foam stock pump startup process P2 in the second column.
Enter Type=Function, End=×, and then in the third column, enter the function number related to Seaverse district valve opening/closing process P3=T30.
, level = 1, type = function, end - 0, and finally enter function number T34, level = 2, type = function, end = O regarding 1lhlAFs <large) startup process P4 in the fourth column.

In the same process, the control table T3 for the Seaverse district valve opening/closing process P3 shown in FIG. 4(b) is created as shown in FIG. 5(b).
) and the NI shown in Figure 4(C).
Control table T for IAFS (large) startup process P4
4 is prepared as shown in FIG. 5(C).

The data constituting each control table TO etc. created on the screen of the display 12 by input from the keyboard 13 is stored in the external storage device 1 in a configuration as shown in FIG.
It is stored in 4.

Description of each item of data shown in FIG. 8 will be omitted.

When executing the seaverse foam monitoring process in which the control table To etc. have been created, the external storage device 14 storing the data of each control table is connected as the external storage device 22 to the control processing device 21 shown in the first figure. After that, by inputting an initial setting signal from the keyboard 26, the initial setting signal is stored in the storage device 23.

Next, when a control start signal is input from the keyboard 26, the control processing unit 21 refers to the data constituting the control table stored in the storage device 23, and the data shown in FIG. Execute the control logic as shown.

Assuming that the Seaverse district valve opening/closing process corresponding to the control table T3 shown in FIG. Refer to the condition access key state of the data corresponding to the processed process P31 (opening process of Seaverse A district name valve), and if it is unprocessed (step S1 in Figure 9), start the task (step S2), tag The interface device 24 connected to number FFF-XV205 (Seaverse A District Name Valve) transmits a signal to open the valve.

When the tag number FFF-XV205 (Seaverse A district name valve) finishes opening, the status of the tag number FFF-XV205 (Seaverse A district name valve) changes from the closed state to the device information table (not shown). A monitoring device (not shown) indicates that the state has changed to the open state.

Next, the control processing device 21 checks whether there is a process with the same level -1 after the second column of the control table (step S3), and the same level = 1 entered in the second column is assigned. Refer to the condition access key status of the data corresponding to process P32 (tank area foam source valve closing process), and if it is unprocessed (step S1), start the task (step S2), tag number FFF-XV206 ( to the interface device 24 connected to the tank area foam source valve);
A signal is transmitted to close the valve.

Similarly, refer to the condition access key state of the data corresponding to the closing process of tag number = FFF-HV-702 (seawater line header main valve) assigned the same level = 1 entered in the last column, and If processing (step S1
), step S2) to start the task, tag number F
Interface device 2 connected to FF-HV-702
4 transmits a signal to close the valve.

When all processes to which the same level=1 has been assigned are completed (step S3), the control processing device 21 refers to the above-mentioned device information table every 500 milliseconds, and processes controls to which the same level=1 has been assigned. Target device, i.e. tag number F
FF-XV20'5, FFF-XV206, -1FFF
- Determine whether or not the processing for HV-702 is completed (steps S4, S5, and S6). When all processing is completed, determine whether or not the next bell = 2 or later exists in the corresponding control table. Confirm in step S7), if it exists, then repeat steps SL and subsequent steps for the processing after Bell=2, but since there are no levels other than level -1 in the control table T3 shown in FIG. 5 (bl). , after performing a final check (step S8), the control process is ended.

As is clear from the above description, according to this embodiment, if the control table creation processing device creates a control table corresponding to the disaster prevention equipment to be controlled, the control processing device thereafter executes control using general-purpose control logic. This eliminates the need to create dedicated control programs for each.

Note that FIGS. 2 to 9 are only one embodiment of the present invention, and for example, the control table creation means 100 and the control logic execution means 200 are the control table creation processing device 11 and control processing device 21 shown in the figures. Although the present invention is not limited to this and many other modifications may be considered, the effects of the present invention remain the same in any case. Further, the disaster prevention system to which the present invention is applied is not limited to the Seaverse foam monitoring process shown in the drawings, and many other modifications may be considered, but the effects of the present invention remain the same in any case.

[Effects of the Invention] As described above, according to the present invention, when a new disaster prevention system is installed or changed, it is only necessary to create a control table that is compatible with the new disaster prevention system, and there is no need to create a dedicated control program. , development man-hours are significantly reduced.
