Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a program creating device for creating a program for simulating the operation of various plants.

[0002]

2. Description of the Related Art In various plants such as a chemical plant and a power plant, a medium such as liquid / gas / electricity / heat or energy (hereinafter referred to as “entity”) is handled. In operations related to plant control such as testing and verification of control software for controlling these plants and operation training, simulation is used in terms of safety, cost and efficiency.

Specifically, the operation of a plant is simulated by a computer program. In most cases, this type of program is created by humans based on a plant system diagram, etc. It takes a lot of work. For the purpose of reducing this work load, for example, Japanese Patent Laid-Open No. 64-38804 proposes a modeling method for creating a simulator.

[0004]

However, even if such a method is used, the creation work is performed manually by a human being,
There are still many demands for reducing the work load.

On the other hand, a technique such as Japanese Unexamined Patent Publication No. 4-273524 (a method for synthesizing components from a connection relation) has been proposed. This technique realizes the operation of a plant by preparing a partial program that represents the operation of each part that constitutes the plant and connecting the parts (each partial program). When this technique is used, a simulation program can be automatically generated and used if sufficient types of parts are prepared in advance. However, with this method, it is very difficult to create a part, and the procedure when the user creates a part is complicated.

For example, in the above-mentioned Japanese Patent Laid-Open No. 4-273524, the component / synthesis unit is a device that directly controls or a device that functions as a sensor. But,
In the case of parts where it is assumed that three or more devices are connected to one connection point (FIG. 11), the operation pattern of each part must be changed according to the specific connection relationship. For this reason, first, the structure of the parts becomes a very complicated structure. Therefore, there is a problem that not only all the parts cannot be prepared in advance, but also the burden of making parts by the operator increases.

The present invention has been proposed in order to solve the above-mentioned problems of the prior art, and an object thereof is to provide a program creating apparatus that makes parts creation efficient. Another object of the present invention is to provide a program creation device that performs a rational simulation in accordance with the actual cause and effect. Another object of the present invention is to provide a program creation device that can be easily initialized during simulation.

[0008]

In order to achieve the above object, the invention of claim 1 is a program creating apparatus for creating a program for simulating the operation of a plant, wherein the plant performs a function for each type. The program creation device includes a functional device and a transmission device that transmits at least one of a medium and energy between the functional device, and the program creation device uses an attribute to be embodied for each group of the desired plural devices. A first setting means for setting a template that generally represents the operation of the group as a prototype of a part of the program, and the configuration of the plant to be simulated, the group, the attribute, and Input means for inputting as a connection relationship of groups, and corresponding to each group included in the described configuration For each template, the attributes included in the template are specifically set to generate a partial program that is a part of the program, and the partial programs are synthesized based on the connection relationship in the configuration of the plant. It is characterized in that it has a synthesizing means for creating a program and an executing means for executing the synthesized program.

According to a second aspect of the present invention, in the program creating apparatus according to the first aspect, there is provided second setting means for setting a priority order of execution for each process included in the operation of the group, and the execution is performed. The means is configured to execute the program based on this priority order.

According to a third aspect of the present invention, in the program creating apparatus according to the first aspect, the attribute includes a variable indicating an initial state to be determined at the time of simulation.

[0012] According to a fourth aspect of the invention, in the program creating apparatus according to the first aspect, the attribute includes a state variable of the transmission device, and the partial programs having the connection relationship share this state variable. As a result, the behavior of at least one of the medium and energy is exchanged between partial programs.

[0012]

The present invention having the above structure has the following functions. That is, in the invention of claim 1, from the functional equipment (controlled equipment, sensor equipment, etc.) and the transmission equipment (pipe, electric wire, etc.) constituting the plant, the functional equipment and the transmission equipment connected to the equipment, or 3 Create a group by combining two or more transmission devices. This group will be the components that make up the plant.

Then, the operation of each group is represented by the state and processing, and is used as a template which is the original form of the partial program. This template is a template generally represented by attributes such as state variables and various parameters that should be embodied during program synthesis. The operation of each group is a state change of a controlled device according to a control command, a behavior (state change or transmission) of a medium or energy (referred to as “entity” in this specification) such as liquid / gas / electricity / heat due to control, Changes in sensor devices due to behaviors, etc. are described by the state of each device, necessary initial state and attribute, processing for changing the state, and start condition of the processing.

The structure of the plant to be simulated is described as groups and attributes and their connection relations. In program creation, various attributes included in the template corresponding to each group are replaced with concrete names and values, and the attributes are combined. Is set to generate partial programs, and these partial programs are synthesized based on the connection relationship in the plant configuration to synthesize the simulator program.

The synthesized program is a set of states and processes, and the executing means is a "state" in which an initial state needs to be defined.
If there is any, after determining this, each process satisfying the activation condition is detected, and each process is executed in a predetermined order.

As described above, according to the present invention, if the operation of the group is described in the template, the description of the plant configuration can be easily made by the group and its connection relation and attribute. In addition, the transmission of events between groups can be expressed by a unified model called the state variable of the transmission device, which facilitates the creation of templates.

In particular, the behavior of the transmission device is simple,
In a group of a plurality of transmission devices, it is sufficient to omit the transmission between the individual devices and express only the operation between the start point and the end point of the transmission. In addition, a group of multiple transmitters is generally more general than other groups, further reducing manual production.

According to the second aspect of the present invention, since the priority order of execution can be set for each process, the execution order is not governed by the described order, and rational simulation can be performed according to the actual cause and effect.

According to the third aspect of the invention, the desired initial state can be easily set as the concrete content of the variable.

Further, in the invention of claim 4, since the state of the entity is transmitted between the partial programs by a simple configuration in which the partial programs having the connection relationship share the state variable of the transmitting device, the partial programs can be synthesized. It's easy.

(1) Configuration of Embodiment This embodiment is a program creating apparatus for creating a program for simulating the operation of a plant.
Corresponds to 4. An object of the present embodiment is to provide a program creation device that makes parts creation efficient. Another object of the present embodiment is to provide a program creation device that performs a rational simulation in accordance with the actual cause and effect. Further, another object of the present embodiment is to provide a program creating apparatus which can easily perform initial setting at the time of simulation.

First, FIG. 1 is a functional block diagram showing the configuration of a program creating apparatus (hereinafter referred to as "this apparatus") of this embodiment. The program creating apparatus of the present embodiment treats a plant as including a functional device that performs a function for each type and a transmission device that transmits at least one of a medium and energy between the functional devices.

As shown in FIG. 1, the present apparatus generally uses the attributes to be embodied for each desired group of a plurality of the devices as an operation of the group as a prototype of a part of the program. First setting means 1 for setting a template that is represented schematically, and input means 2 for inputting the configuration of the plant to be simulated as the group, the attribute, and the connection relationship between the groups. With.

Further, the present apparatus is a part of the program by concretely setting the attribute included in the template for each template corresponding to each group included in the described configuration. It has a synthesizing unit 3 for generating partial programs, synthesizing these partial programs based on the connection relation in the configuration of the plant to create the program, and an executing unit 4 for executing the synthesized program.

The present apparatus also has a second setting means 5 for setting the priority order of execution for each process included in the group operation.

(2) Actions and effects of the embodiment FIG. 2 shows an example of a chemical plant to be simulated in this embodiment. This plant includes a functional device that performs a function for each type and a transmission device that transmits at least one of a medium and energy between the functional devices. The functional devices are specifically controlled devices and sensor devices. Further, the controlled device is a device that directly controls, for example, a valve or the like for liquid / gas, a relay or the like for electricity, and an electric heater or the like for heat. Further, the sensor device is a device that functions as a sensor, for example, a liquid /
Gas is a flow meter, electricity is an ammeter, and heat is a thermometer. The transmission device is a device that connects functional devices to transmit the substance, and is a pipe or the like for liquid / gas, an electric wire or the like for electricity, or a conduction pipe or the like for heat. Examples include pipes and electric wires. The equipment used here is a storage can,
Use pipes, valves and flow meters.

[Selection of Group] FIG. 3 shows a procedure for creating a simulation program for a plant including the above elements in this embodiment. FIG. 3 shows a procedure in the case where the setting of the template, the composition of the program, and the execution of the program are continuously performed. After once setting the template for each group, it is sufficient to repeat only the procedure from step 34 when synthesizing the programs for the other plants configured from the set group.

In this procedure, first, a desired group of a plurality of these devices is determined (step 31). Here, FIG. 4 and FIG. 5 exemplify the types of parts that are the basis of program composition. That is, as a group, FIG.
As illustrated above, "a set of controlled devices or sensor devices and transmission devices" or "a set of three or more transmission devices" as illustrated in the upper part of FIG. 5 is defined.

For the determination of this group, for example, for each of the controlled device and the sensor device, the end of the device to which the transmitting device is connected is enumerated, and the specific transmitting device is specified for each end. Can be done by typing what is connected. In this case, the set of the functional device and the transmission device connected to this functional device is a group. For example, the unit of the group centering on the valve is (pipe-
Valve-pipe).

Further, when there is a possibility of branching among the transmission devices, the number of possible branches is n ₁ , n ₂ , n ₃ , ...
..., and the n _m,

[Equation 1] On the other hand, a group in which n transmission devices are connected is created. For example, for pipes (pipe-pipe-pipe)
Prepare a group corresponding to.

Subsequently, the user sets the template for each group from the first setting means 1 for each determined group (steps 32 and 33). Here, the template generally represents an operation / physical phenomenon as a set of the group using an attribute to be embodied as a prototype of a part of the program. Here, "generally" means that various attributes such as "device status" appearing in the description of the template can be replaced with specific information such as a specific name or a value during synthesis. Means For example, include a variable in the state name,
Such a permutation can be achieved by determining that variable during composition.

In the template, as the operation of the group, the state change of the controlled device caused by the control command,
Describe the state change and communication about the substance, and the change of the sensor device caused by the state change and communication about the substance.

The change in the state of the controlled device caused by the control command is specific to the device that directly controls, and corresponds to, for example, the opening operation in response to the opening command of the valve.
The state change or transmission related to the entity is the state change related to the entity caused by the state change of the controlled device caused by the control command, or the operation in which the state change of the entity at one end connected to the device is transmitted to the other end. Show.

For example, (pipe 1-valve-pipe 2)
When the pressure on pipe 1 changes with the template of
The operation of transmitting the pressure change to the pipe 2 corresponds to this. In the finally synthesized program, the connected parts share a variable corresponding to the state related to the entity of such "equipment transmitting an entity", and the state change or transmission related to this entity causes The state of the entity will be transmitted between the parts.

Further, the change of the sensor device caused by the change of the state of the substance or the transmission thereof realizes the operation of the sensor when there is a sensor for monitoring the change of the state of the substance. Pipe 1-
This is an operation such as changing the sensor output value of the flow meter when the flow rate of this part changes with the template of the flow meter-pipe 2).

These operations are performed by the "state" of each device constituting the template, the "process" for changing the state of each device, and the "start condition" of the process (what kind of state the process starts). Described by Further, the second setting means 5 determines the execution order of each “processing”.
Also, describe the initial state, and use this as a variable when determining the initial state during simulation.

Next, an example of a plant template that satisfies the following constraints will be shown. -In a pipe-valve-pipe connection, the pipe diameters of both poles are the same. -It is assumed that liquid does not flow in both directions to one system.・ Of the entities, only liquids should be handled. Examples of templates for the groups (pipe-storage can-pipe), (pipe-valve-pipe), and (pipe-flowmeter-pipe) are shown in FIGS. 6, 7, and 8, respectively.

In this example, the part name after the class is
After that, change the variable to be replaced with the concrete name to (...)
Parameters to be given to the part are included after "meter" (there is no description), state name and initial value are described after "slot", and processing is described after "method". The processing is described in the form of "if (starting condition) then processing body priority priority". Pipe-storage can-pipe template (p
-Can-p) will be described in detail as an example.

That is, the pipe has two ends. $
Pipe1Tan1 is a variable indicating the end that is not connected to the storage can. Also, $ Pipe is the name of the pipe, $ Pipe1Tan2 is the end of the one connected to the storage can, $ Can is the name of the storage can, and $ Pipe2Tan1 is the one of the pipe connected to the storage can of the other pipe. The end is $ Pi
pe2 is a variable that represents the pipe name, and $ Pipe2Tan2 is a variable that represents the end of the pipe that is not connected to the storage can.

“Pipe name.Pipe end.press” is the pressure from the “Pipe end” of the “Pipe name”, and “Pipe name.Pipe end.flow” is the liquid from the “Pipe end” of the “Pipe name”. The flow is $ Can. water-qua
The amount of liquid contained in the storage can is calculated as $ Ca
n. capacity is the capacity of the storage can, "pipe name". capacity indicates the diameter thickness of the "pipe name". Further, f () is a function for calculating the flow rate from the pressure and the pipe diameter, and g () is a function for calculating the pressure applied to the lower pipe from the amount of liquid contained in the storage can. Here, the priority order is described as a fixed value, but a more detailed simulation can be performed by using this as a function.

[System Input and Program Synthesis] Next, the configuration of the plant to be simulated is described as groups, attributes, and their connection relationships (step 3).
4). Then, each template corresponding to each group included in the described configuration is used (step 3
5, 36), by setting a concrete name or value to the attribute (state name etc.) included in the template (step 37), a partial program which is a part of the program is generated (step 38). In this case, the transmission device will be shared by the two groups unless it is at the end of the grid.

Such an embodiment can be realized by, for example, a template (pipe 1-pipe 1), a pipe (pipe 1), and a pipe B (pipe 1), which corresponds to a set of pipes named pipe 1 and pipe B. In the valve-pipe 2), "<valve> open state" means "V1 open state", "<pipe 1> flow rate" means "pipe A flow rate", and so on.

For example, when the templates shown in FIGS. 6, 7 and 8 are set, the following groups can be selected from the plant configuration: pipe A-valve A-pipe B pipe B-can A-pipe C pipe. C-valve B-pipe D pipe D-flow meter A-pipe E pipe E-valve C-pipe F pipe F-can B-pipe G pipe G-valve D-pipe H are used.

As attributes (parameters), the pipe diameters are all 20 cm, and the storage can capacity is 500 k.
Let l. As a result, a specific partial program is generated from the template (step 38).

For example, pipe B-can A-pipe C, pipe C-valve B-pipe D will be described as an example. It is assumed that the pipe ends are x and y, respectively, and that the pipe B is connected to the can A at the y end and the pipe C is connected to the can A at the x end. Here, the group is selected, but first, the pipe B-the can A-the pipe C
The template of pipe is pipe B, can A is a storage can,
Since pipe C is a pipe, it is p-can-p.

Next, a character example representing a concrete name of a variable such as $ Pipe1Tan1 = x $ Pipe1 = pipe B $ Pipe1Tan2 = y $ Can = can A $ Pipe2Tan1 = x $ Pipe2 = pipe C $ Pipe2Tan2 = y Replacement, Substitution of Parameters: Can A. capacity = 500 Pipe B. capacity = 20 pipe C.I. Similarly, capacity = 20 is performed by replacing each character example. The partial program generated as a result is shown in FIG.

Similarly, a partial program for pipe C-valve B-pipe D is created from the template p-y-p. The result is shown in FIG. In this result, the variable below slot indicates the state and its initial value, and the method below method indicates the process. Similarly, partial programs are created for other units as well, and for these partial programs, variables, initial values, and processing are combined into one based on the connection relationship in the plant configuration and combined to form a simulation program (step 39).

[Program Execution] The combined program is a set of states and processes. In order for the execution means 4 to execute this, if there is a “state” that requires the definition of an initial state, after defining this, each process that satisfies the start condition is detected, and each process is given priority as described above. The processes are executed in the order from the highest rank or a predetermined order (step 40). When there are a plurality of items having the highest priority, the one to be executed is selected by a selection rule such as “select [process] located at the top of the program”.

At this time, the pipe C. x. press, pipe C.I. y. pr
ess = 1, pipe C.I. x. flow, pipe C.I. y.
The flow is shared, and the flow and pressure are transmitted between each partial program via such a shared variable. Also,
For example, to open valve B, use "valve A.open-c
“Mand” to “yes” and to activate the flowmeter, use “Flowmeter A. This is done by setting "set" to "yes".

As described above, in this embodiment, if the operation of the group is described in the template, the system can be easily described by the group, its connection relationship, and attributes. In addition, the transmission of events between groups can be expressed by a unified model called the state variable of the transmission device.
It also makes it easier to create templates.

In particular, the behavior of the transmission device is simple,
In a group of a plurality of transmission devices, it is sufficient to omit the transmission between the individual devices and express only the operation between the start point and the end point of the transmission. In addition, a group of multiple transmitters is generally more general than other groups, further reducing manual production.

Further, in this embodiment, since the priority order of execution can be set for each process, the execution order is not governed by the described order, and a rational simulation can be performed according to the actual cause and effect.

Further, in this embodiment, the initial state to be determined at the time of simulation can be easily set as the concrete content of the variable and the desired initial state can be easily set as the concrete content of the variable.

Further, in this embodiment, since the state of the entity is transmitted between the partial programs by a simple structure in which the partial programs having the connection relationship share the state variable of the transmission device, the partial programs can be easily synthesized. is there.

It also includes other embodiments as illustrated below. For example, the invention is applicable to any type of plant, not just chemical plants. Further, the types of functional devices and transmission devices, the number of devices per group, the content of attributes, etc. can be freely determined.
