Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engineering tool and an engineering system for a digital controller for a plant such as a nuclear power plant.

[0002]

2. Description of the Related Art A conventional engineering tool will be described with reference to the drawings. FIG. 15 is a diagram showing a configuration of a conventional engineering tool as disclosed in, for example, Japanese Patent No. 2660603.

In FIG. 15, reference numeral 11 is an engineering tool having a display unit such as a display and an input unit such as a keyboard and a mouse. 11 a shows two screen examples of the control logic display screen displayed on the display unit of the engineering tool 11. 11c is an input / output definition screen displayed on the display part of the engineering tool 11, 11d
Is a simulation setting screen displayed on the display unit of the engineering tool 11. Reference numeral 13 is a digital controller, which is connected to the engineering tool 11.

Next, the operation of the conventional engineering tool will be described with reference to FIG.

Conventionally, a control system using a digital controller in a nuclear power plant has tools for design and maintenance. This tool is a laptop type, notebook type, desktop type personal computer or the like, and is called an engineering tool 11. The engineering tool 11 has a role of programming a control program, which is software for controlling the digital control device 13, various settings, and monitoring of a plant state.
The control program programmed by the engineering tool 11 and the setting information for setting data are transferred to the digital control device 13, and the digital control device 13 performs various controls in accordance therewith. On the contrary, the digital control device 13 transfers information such as the control state of the plant to the engineering tool 11. The engineering tool 11 displays the information on the screen of the display unit,
The plant monitor watches the screen and monitors the plant status.

The control program created by the engineering tool 11 is generally a POL (Problem Oriented Lang) suitable for control.
It is programmed using a language called "age".

In programming the control program, an input device (input card) of the digital control device 13 is used.
Since the parameter of can not be set, the value was set after programming the control program. This setting includes, for example, parameter setting of the input analog detector. Here, if a value exceeding the detection range is set in the analog detector, the digital control device 13 sounds an alarm indicating an abnormality when the value detected by the analog detector corresponds to the set value. Control can be performed.

When performing the parameter setting as described above,
The control logic display screen 11a for displaying the control circuit diagram is switched to the input / output definition screen 11c, and this input / output definition screen 1
A value was input to the input field in 1c by operating the input section of the engineering tool 11. The value input by this operation was set in the control program and control was possible.

The control program is transferred to the digital controller 13 by operating the engineering tool 11. The digital control device 13 periodically executes the transferred control program. However, for example, when the input device of the digital control device 13 is replaced during execution, if the input device is simply removed, the digital control device 13 recognizes the abnormality and issues a command to sound an alarm corresponding to the abnormality. Sometimes sent to output. In order to avoid such a situation, a simulation is being performed. In this simulation, when a value recognized as a normal value is set in the control device in the control circuit diagram that is recognized as abnormal, the normal value is set in the control program. Then, when the simulation is executed, the digital control device 13 controls based on the normal value. As a result, normal control processing can be continued even if the input device is removed.

When setting such a simulation, the control logic display screen 11a is switched to the simulation setting screen 11d, and a value is input to the input field of the simulation setting screen 11d by operating the input section of the engineering tool 11. Further, by switching to the data setting screen for simulation and inputting a value by operating the input section, the input value is set in the control program.

The hardware designer and the software designer of the control circuit are designed by the digital controller 13
A number (tag) corresponding to the control device of is attached, and the control device is called by that number and used for design. For example, in the control device of the digital control device 13, the input device may be an analog detector and the output device may be a motor.

When the hardware connection of the input device and the output device to the digital controller 13 is completed, the digital controller 1 is actually selected from the connected input devices.
In the control program, the input device that takes in the signal to 3 and the output device that actually sends the signal from the digital control device 13 among the connected output devices are defined.

This definition is defined by the engineering tool 11
The control logic display screen 11a displayed on the display part of the is switched to the input / output definition screen 11c, and a number corresponding to the input device and the output device to be connected by the operation of the input part of the engineering tool 11 in the input field on the screen. It was defined in the control program by inputting the address where each device is located. Such a definition is called allocation of input / output devices.

The created control program is tested for operation confirmation and examined for processing time. When measuring this processing time, after performing a test of operation confirmation, the control program is transferred to the digital control device 13, and the control program is actually executed by the digital control device 13, and the actual processing time at that time is measured. Was being measured.

Engineering tool 11 as described above
Usually constructs an engineering system with the above-mentioned personal computer or the like, and performs programming, various settings, plant monitoring screen display, and the like.

[0016]

However, the conventional engineering tool as described above has the following problems.

Normally, there are a plurality of control steps that are periodically performed. When the control program corresponding to this control step is executed by the digital control device 13, the plurality of steps are sequentially processed.
However, in reality, for example, since the step 2 is not executed during the execution of the step 1, the execution of the step 2 is avoided until the step 1 is completed, and other steps are not executed during the execution of the certain step. . In this case, engineering tool 1
1 had only a programming function to process the processes in order, so every time a control program was created,
Even if a process that avoids a process is incorporated into each process in the control program and each process is started during execution of a certain process, the normal process in the process is avoided and the incorporated avoidance process is executed. It was However, the control circuit diagram (control logic) corresponding to the control program has a problem that the control circuit diagram becomes complicated because the normal process and the process avoidance process are mixed.

Further, in the parameter setting of the input device,
By operating the input part of the engineering tool 11, the control logic display screen 11a is changed to another input / output definition screen 1
There is also a problem that the screen development work becomes complicated because it is necessary to switch to 1c, set a parameter value, and switch to the control logic display screen 11a again to check the control process state.

Furthermore, when setting the simulation,
By operating the input section of the engineering tool 11, the control logic display screen is changed to the simulation setting screen 11d.
Then, the simulation execution flag was set. Furthermore, the data was set by switching to the data setting screen for simulation. Further, the confirmation of the control process state after the setting has to be switched to the control logic display screen 11a again, which causes a problem that the screen development work becomes complicated.

The assignment of the input / output device of the digital control device is performed by switching to the input / output definition screen 11c.
The input / output definition screen 11c is a tabular definition screen and is assigned such that the address where the input / output device is located and the number corresponding to each device are input in the input field on the input / output definition screen. Was there. However, the assignment method is not such that the input device and the output device are actually connected to the digital control device 13 as if they were hardware, and thus there is a problem that it is difficult for the designer to understand.

When the processing time of the created control logic is to be measured, the control program must be actually transferred and executed by the digital control device 13. If the execution time is exceeded, There was also a problem that the control logic had to be recreated and the execution method had to be devised.

Further, since such an engineering tool 11 is composed of one personal computer, the control logic can only be created by one engineering tool. As a result, for example, even when it is desired to create a control program for a control process having a plurality of processes, there is a problem that a plurality of workers cannot share the processes and simultaneously create each process.

The present invention was made to solve the above-mentioned problems, and a first object thereof is to provide an engineering tool equipped with an automatic programming system capable of creating a control program capable of skipping a process. I will get it.

A second purpose is to monitor the control logic display screen of the engineering tool displaying the control status online while the control is being executed in the digital control device, and input the control logic display screen on the control logic display screen. (EN) An engineering tool provided with an input device parameter setting system capable of setting device parameters.

A third object is to monitor the control logic display screen on the display part of the engineering tool displaying the control status online while the control is being executed in the digital control device, and perform a simulation on the control logic display screen. To obtain an engineering tool equipped with a simulation data setting system that enables data setting.

A fourth object is to describe the equipment connected to the digital controller as an input and the equipment connected to the output on the definition screen prepared for each input / output device, thereby assigning the input / output device of the digital controller. It is intended to obtain an engineering tool equipped with an input / output device allocation system that enables the above.

A fifth object is to obtain an engineering tool having a processing time calculation system capable of predicting the processing time without actually executing the control program on the digital controller.

A sixth object is to obtain an engineering system in which a plurality of workers can simultaneously perform a creation work for a control circuit diagram of a control process having a plurality of processes when creating the plurality of processes. It is a thing.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiment 1. An engineering tool according to Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is a first embodiment of the present invention.
It is a figure which shows the structure of the system containing the engineering tool which concerns on. In each figure, the same reference numerals indicate the same or corresponding parts.

In FIG. 1, reference numeral 11 is an engineering tool for a personal computer such as a laptop type, a notebook type and a desktop type. This engineering tool 11
Has an input unit such as a keyboard and a mouse and a display unit such as a display. Reference numeral 11a shows two screen examples in which a control circuit diagram called a control logic created by the engineering tool 11 is displayed on the display unit. 11a1 to 11a5 show the screens of the engineering tool 11 in which the control logic is displayed on the display section for each process.
Reference numeral 12 shows a JUMP icon drawn in each step. 1
Reference numeral 3 denotes a digital control device connected to the engineering tool 11.

Next, the operation of the engineering tool according to the first embodiment will be described with reference to the drawings.

The digital control device 13 is used as a control device for controlling a plant such as a nuclear power plant. The digital control device 13 is installed in a plant and collects detection information of various detectors that detect the state of pressure, temperature, etc. of each part of the plant at a constant cycle. Based on this detection result, a calculation is performed to calculate an appropriate operation amount of a hardware device such as a turbine generator installed in the plant so as to maintain the state at a predetermined value, and the hardware device is controlled. Give a signal.

The control program for controlling the digital controller 13 is a software of a control circuit which is a combination of control devices such as a primary delay controller for controlling the hardware devices. Such a control program is created by the engineering tool 11
Done by an automatic programming system stored in. In addition to this, the engineering tool 11 also includes a monitoring screen display system for displaying the control status of the digital controller 13 during operation on the screen.

The automatic programming system is a system that automatically creates a control program corresponding to the control circuit diagram when a control circuit diagram in which each control device is combined with the display part of the engineering tool 11 is created.

To input the control device to the screen of the display part of the engineering tool 11, first, a control device menu screen (not shown) in which various control devices are graphically displayed like icons and a control logic display screen are displayed. 11a and 11a are displayed on the display unit of the engineering tool 11. For example, it is an image that the control device menu screen is displayed on the left side of the display part of the engineering tool 11 and the control logic display screen 11a is displayed on the right side. Then, a control device icon is selected from the control device menu screen on the screen by operating the input unit of the engineering tool 11. When selected, the control device icon is displayed on the control logic display screen 11a. In this way, the control device icon is selected and the control logic display screen 11a is displayed repeatedly to create a control circuit diagram. The automatic programming system creates a control program corresponding to the control circuit diagram created in this way.

Normally, when a control circuit diagram is created, the control circuit is created by dividing it into some units, and the units are called processes (sheets) to distinguish them. For example, if the control circuit is N
When divided into pieces, they may be referred to as step 1 to step N. When programming the control program of such a control circuit, the circuit of each process is, for example, the start mode determination processing 11a1 to the end processing 11a5, which includes the start mode determination processing 11a1 and the end processing 11a5.
As described above, the creation screen is created separately for each process.

The circuit for each process is also created by repeating the same operation as described above, selecting the control device icon from the control device menu screen and displaying the control logic display screen 11a. Further, when the creation of one process is completed, the input screen of the engineering tool 11 is operated to switch to the creation screen of the next process, and the circuit of the next process is created by the same operation as described above. After that, the same operation is performed until the final step. Through the operations described above, the automatic programming system automatically programs the control program corresponding to the control circuit having a plurality of steps.

With this automatic programming system, the control logic of the control process executed periodically is created. This control process is a control logic that processes only the process 1 in a certain cycle and processes only the process 2 in a certain period, such as the start mode determination process 11a1 to the end process 11a5. Such a control logic is created using the JUMP icon 12 on the control device menu screen. The JUMP icon 12 has a function of shifting to a designated process.

The steps of this control process are the start mode determination process 11a1, the process 1 process 11a2, and the process 2 process 1
1a3, ... Process N process 11a4, end process 11a5
Have. The startup mode determination process 11a1 manages the startup flag of each process from the process 1 process 11a2 to the process N process 11a4. The start mode determination processing 11a1 determines whether or not each process is started in the state of the start flag. The initial value of this activation flag is OFF.

The operation of the control process is shown by a flowchart.
FIG. 3 is a flow chart showing the operation of the control program created by the engineering tool automatic programming system according to the first embodiment of the present invention.

Steps 301 to 305 are condition processes for starting each process existing in the start mode determination process 11a1. This is a process of referring to the state of the activation flag of each step described above. Step 306 is process 1 process 11a2, step 307 is process 2 process 11a3, step 308 is process 3 process, step 309 is process 4 process, step 310 is process N process 11a4, step 3
Reference numeral 11 indicates a termination process 11a5.

In step 301 in the first cycle, the start mode determination processing 11a1 refers to the step 1 start flag and determines whether to start the step 1 processing 11a2. In the start mode determination processing 11a1, the process 1 start flag is OFF.
Is confirmed, the process 1 processing 11a2 is determined to be activated, and the process 1 activation flag is switched to ON. Then, the program of the JUMP icon 12 is executed to jump to the process 1 processing 11a2, and in step 306, the process 1 processing 11a2 is executed. Process 1 processing 11a
When step 2 is started, the program of the JUMP icon 12 in the process 1 process 11a2 is executed, and all the subsequent process 2 process 11a3 to process N11a4 process are skipped,
The process jumps to the end processing 11a5 of step 311.

Second cycle, at this point, process 1 process 11a2
Is still running. In step 301, the startup mode determination processing 11a1 refers to the process 1 startup flag,
Confirm that the process 1 start flag is ON. This completes Step 1 from Step 302 to Step 305.
It is determined that the process 11a2 to the process N process 11a4 are not all started, and the end process 11a5 of step 311 is performed. It is assumed that the process 1 process 11a2 ends at this point. The process 1 processing 11a2 turns off the process 1 start flag.
Switch to.

Since the process 1 process is completed in the third cycle, in step 301 the start mode determination process 11a1
Does not start the process of step 1. Next, step 302
In step 2, process 2 start flag is referred to and process 2 process 11
It is determined whether to activate a3. Startup mode determination processing 11
The a1 confirms that the process 2 activation flag is OFF, determines that the process 2 processing 11a3 is activated, and switches the process 2 activation flag to ON. Then, the program of the JUMP icon 12 is executed to jump to the process 2 processing 11a3, and in step 307, the process 2 processing 11a.
Execute 3. When the process 2 process 11a3 is started, the program of the JUMP icon 12 in the process 2 process 11a3 is executed, and all the processes from the subsequent process 3 process to the process N11a4 are skipped, and the end process 11 of step 311 is executed.
Jump to a5. Thereafter, in the same manner, the processes are sequentially performed from the process 3 process to the process N process 11a4.

In this way, a control program for a control process that can skip the process and proceed with the process is created. This control program is also created using the automatic programming system of the engineering tool 11 in the same manner as described above.

FIG. 2 is a flow chart showing the operation of the engineering tool according to the first embodiment of the present invention.

First, in the case of creating the activation mode determination processing 11a1, in steps 201 and 202,
The control device menu screen and the control logic display screen 11a are displayed on the display unit of the engineering tool 11. The control device icon is selected from the control device menu screen, and the processing of the start condition of each process is plotted. Beyond each start condition, JUMP added to the control device menu screen
Draw the icon 12. In this way, step 2
The control device icon is selected from the control device menu at 03 and the display of the selected control device icon at step 204 is repeated to draw the activation mode determination processing 11a1.

Process 1 process 11a2 to process N process 11a
In step 4, when the processes are started, the JUMP icon 12 is drawn so as to be executed. Also in the end processing 11a5, the control device icon is selected from the control device menu screen to perform drawing. With the above-described operation, steps 202 to 206 are repeated and printing is performed up to the end processing. When the control logic is created in this way, the automatic programming system automatically creates a control program corresponding to the control logic in step 207.

Next, the JUMP icon 12 drawn from the start mode determination processing 11a1 to the process N processing 11a4.
Set the parameters to. In step 208, when the JUMP icon 12 displayed on the control logic display screen 11a displayed on the display part of the engineering tool 11 is selected on the control logic display screen 11a by operating the input part of the engineering tool 11, step 209 At, a parameter setting screen is displayed near the JUMP icon 12. And step 2
In 10, the operation of the input part of the engineering tool 11 is used to input the process of the transfer destination in the input field on the parameter setting screen. In this case, J in the process 1 process 11a1
The end processing is input to the UMP icon 12. This input value is set in the control program. As a result, when the JUMP icon 12 is entered in the process 1 processing 11a2,
The program of the MP icon 12 is executed, and the end processing 1
It is possible to shift to 1a5. Similarly, other JUMP
With respect to the icons 12 as well, setting a migration destination for each JUMP icon 12 enables migration to that migration destination.

As described above, by creating the control logic using the JUMP icon 12 every time, it is not necessary to study the processing for avoiding the steps that are not processed, and the efficiency of the control logic creation work can be improved. .

Embodiment 2. An engineering tool according to Embodiment 2 of the present invention will be described with reference to the drawings. FIG. 4 is a diagram showing a parameter setting screen of the input device (input card) of the engineering tool according to the second embodiment of the present invention.

In FIG. 4, 11a6 shows a control logic display screen displayed on the display part of the engineering tool 11. 41 is the control logic display screen 11

Next, the operation of the engineering tool 11 according to the second embodiment will be described with reference to the drawings. FIG. 5 is a flowchart showing the operation of the engineering tool according to the second embodiment of the present invention.

After transferring the control program created in the first embodiment to the digital controller 13, the parameters are set in the input device. For example, in the case where an input device such as an analog detector connected to the input device of the digital control device 13 is controlled to sound an alarm when the value exceeds a detectable value, the detection range of the input device is changed. The above control becomes possible by setting in the control program. This setting is performed by the input device parameter setting system provided in the engineering tool 11.

For example, when setting a parameter to the input device icon 42 indicating an analog input, first in step 501, the input device icon 42 on the control logic display screen 11a6 displayed on the display part of the engineering tool 11 is engineered. It is selected by operating the input section of the tool 11. When selected, in step 502, the input card parameter window 41 is displayed near the input device icon 42 on the control logic display screen 11a6. Next, in step 503, parameters are input to the input field in the input card parameter window 41 by operating the input section of the engineering tool 11. With the above operation, step 504

In order to avoid such a situation, there is a simulation function. Before executing this simulation function, in the simulation data setting system,
When simulation data recognized as a normal value is set in the control device icon in the control logic for recognizing an abnormality, the simulation data is set in the control program. Then, when the simulation function is executed, control is performed based on the set simulation data, so that normal control processing can be continued even when the device is replaced.

This simulation data setting system is provided in the engineering tool 11, and this data setting is performed on the control logic display screen 11a7 displayed on the display part of the engineering tool 11. In the control device icon on the control logic display screen 11a7, for example, when setting simulation data to the control device icon 62, first, in step 701, by operating the input unit of the engineering tool 11,

Regarding the output processing 138, the processing time required for each output signal 138 is recorded in advance in the output processing time table of the engineering tool 11 for each signal type of the output signal. In step 1204, the processing time calculation system acquires the processing time required for one output signal corresponding to the signal type for all the signal types in the output information table 112, and obtains the sum of the processing times. With the above calculation,
The processing time required for the output processing 139 is calculated.
