Description

  The present invention relates to a technology of an information control system and an information control method.

  There is a waterfall model as a program development model of an information control system. The entire project is divided into several processes, and the deliverables (documents such as specifications and designs) in each process are clearly defined, and the subsequent processes are sequentially performed based on the deliverables. The waterfall model is a document-driven development process aimed at applying the principle of “definition by specification”.

  For example, in an information control system such as a power system, a train operation management system, and a water and sewage management system, a “system specification” is created between the orderer and the contractor at the time of ordering the system. This system specification is a document for defining the state of equipment (equipment) constituting the system. In addition, the system specification is an important interface document among the orderer, the contractor, the designer, and the producer (coding). Therefore, in the system specification, various explanations regarding the state of the device are written in sentences such as Japanese.

  Further, a reserved word file in which syntax rules and execution rules for each reserved word are associated is defined, and a processing method of an execution program is disclosed using a script using a reserved word in the business process definition file (for example, , See Patent Document 1).

JP 2005-149339 A

  However, in the technique of Patent Document 1, the business process definition is described by a simple script, but there remains a problem of creating a script for the contents of the system specifications of the business process.

  There are cases where the description of the system specification is basically ambiguous or missing. For example, Japanese may be interpreted multiple times in one sentence. Further, for example, in the system specification, it is often described as “Zoom when not in the state of XX” by a Japanese sentence.

  A designer or producer cannot produce a control program unless the conditions under which the “XX state” is not satisfied are clear. Therefore, it is preferable that the system specification document describes a condition that does not hold. However, in the system specification, only the explanation when the “XX state” is established is described in Japanese, and the explanation when the “XX state” is not established is not described. Many. Therefore, even in this respect, the description of the system specification may be ambiguous.

  In addition, the conditions that define the state of the device are often unclear as to whether the conditions are satisfied or not, and it is necessary to be skillful to write all the conditions in Japanese without omission. For example, in the system specification, it is often written as “YY when in the state of XX” by a Japanese sentence. When the “XX state” is satisfied only by one condition, the condition is uniquely determined. Therefore, this sentence is clear. However, when “the state of XX” is satisfied by a plurality of conditions, there is a problem that the conditions for establishing and not satisfying the conditions are often unclear.

  As described above, conventionally used system specifications may have vague descriptions or omissions. Moreover, even if the system specifications that have been used in the past are described in an ambiguous manner, they are misunderstood as if all explanations are clearly understood by the reader only by the description. There was a case.

  Therefore, there has been a problem that the system specification that has been used in the past may induce an ambiguous understanding to the reader. In addition, for example, when the orderer and the contractor confirm the specifications or analyze the requirements, there is a problem that it is difficult to determine the omission of the specification or the validity of the description.

  In addition, for example, when a designer and a producer create a control program, there is a problem that it is difficult to check whether the conditions for each specification are satisfied or not. Furthermore, there has been a problem that equipment (equipment) may not be able to operate properly with the specifications described in the conventionally used system specifications.

  An object of the present invention is to provide an information control system and an information control method capable of clearly defining and executing conditions that define the state of a device to be controlled.

  In order to solve the above-described problem, the present invention is an information control system including an object that is a target constituting a control target system, and an actor that monitors a state of the object and issues a control command to the object. The information control system includes a storage unit and a processing unit, and is an object definition information that stores data items of the structure and state of the object in the storage unit, and a control element that monitors and controls the object. As an actor, there is a monitoring condition for the state of the object, a monitoring item for the object, and actor definition information for storing a setting value for the monitoring item, and the setting value for the monitoring item in the actor definition information is changed. Execution satisfaction condition and actor definition information that changes the setting value of the monitoring item when the execution satisfaction condition is satisfied Further comprising actor control definition information associated with the list of, the processing unit determines whether or not the execution establishment condition is satisfied based on information on the state acquired from the object, By changing the setting value of the monitoring item in the actor definition information described in the list in the actor control definition information in which the execution satisfaction condition is satisfied, the actor related to the actor definition information is executed, and the setting value A change control command is transmitted to the object of the monitoring item.

  According to the present invention, it is possible to clearly define and execute a condition that defines the state of a device to be controlled.

  The information control system according to the present embodiment is not a method in which a program developer decodes a specification and creates a program based on a conventional ambiguous system specification. That is, instead of creating and executing a program based on a system specification, a programless development method based on a system definition is adopted. Therefore, it is important to model the controlled system.

  To model the system to be controlled, the "operator's work" and the "judgment criteria and operation procedure" used in the work are modeled, and the operation (control) such as "equipment value" and "operation plan". It is necessary to do what is necessary for performing. These are hereinafter referred to as “actors” and “objects”, respectively. Details will be described later.

  FIG. 1 is a block diagram showing the configuration of the information control system according to the present embodiment. The information control system 100 includes a processing unit 10 that performs information control processing, a storage unit 20 that stores data when performing information control processing, an input unit 31 that inputs data, an output unit 32 that outputs data, and a network The communication control unit 33 is configured to communicate with the control target system 200 via 300.

  The storage unit 20 includes a RAM (Random Access Memory), a HDD (Hard disk drive) device, and the like. The processing unit 10 is realized by executing a program on the RAM or HDD by one or more CPUs (Central Processing Units). The input unit 31 is a device for inputting an instruction to a computer such as a keyboard and a mouse, and inputs an instruction for starting a program. The output unit 32 is a display or the like, and displays an execution status or an execution result of the processing by the information control system 100. The communication control unit 33 exchanges various data and commands with the devices of the control target system 200 via the network 300. The control target system 200 includes, for example, an electric power system, a train operation management system, and a water and sewage management system.

  The processing unit 10 includes an actor setting unit 11, an object setting unit 12, an actor control setting unit 13, an object control setting unit 14, a monitoring function unit 15 that monitors an object state change in the control target system, and a control of the monitoring function unit 15. A control function unit 16 that issues a control command to the object based on the command and an operation management function unit 17 that manages the operation of the controlled system 200 are provided.

  The storage unit 20 includes an actor DB 21 for storing actor information (actor definition table, actor definition information), an object DB 22 for storing object information (object definition table, object definition information), and terms used for actors and objects. Is defined, and a template DB 24 for storing templates (definition tables) for setting actors and objects is stored. The actor definition table will be described later with reference to FIGS. 3 to 6, 11 to 14, 22, and 23. The object definition table will be described later with reference to FIGS. 7, 8, 15 to 20 and FIG.

  Note that the monitoring function unit 15 has a function of searching for definition words, which will be described later, for the definition tables of the actor DB 21 and the object DB 22, and associates them particularly when the actor is operated. The search function may search the definition word as it is, or may associate a unique ID with the definition word and search based on the ID.

  The contents of the actor and the object, and the actor setting unit 11, the object setting unit 12, the actor control setting unit 13, and the object control setting unit 14 will be described with reference to FIG.

  FIG. 2 is an explanatory diagram showing the relationship between actors and objects. In this embodiment, an accident monitoring of an electric station of a power system will be described as an example. An electric station is a power plant, a substation, or the like. An object is necessary for business (control). In the case of an electric station, an object includes an electric station, a bus bar constituting the electric station, a relay, a circuit breaker, and the like. Also, the drawing pattern of the monitoring screen and the alarm for monitoring can be said to be objects. An actor refers to an operator's business or control function, and includes an instruction operation function, a screen monitoring function, and a response function when a state changes. In FIG. 2, as the actor, for example, there are a drawing pattern operation instruction, an electric station state correspondence, a bus state correspondence, a relay state correspondence, a breaker state correspondence, and the like. That is, the function requested as the control target system is defined as an actor, and the data used by the actor is defined as an object.

  Returning to FIG. 1, the actor setting unit 11 stores the defined actor definition table in the actor DB 21 that is set based on the actor definition table in the template DB 24. Similarly, the object setting unit 12 is set based on the object definition table in the template DB 24 and stores the defined object definition table in the object DB 22.

  The actor control setting unit 13 is a part that sets the operation of the entire actor, sets a plurality of actors as an actor group for each function of the controlled system, and sets the execution order of the actors, the timing of capturing object data, and the like. The actor control setting unit 13 sets a plurality of actor groups.

  The object control setting unit 14 is a part for setting the operation of the entire object, sets a plurality of objects as an object group for each function of the control target system, and controls the reflection of data between the same objects across the CPUs. Set. The object control setting unit 14 sets a plurality of object groups.

  The set actor group and object group are executed in the information control system 100 in accordance with rules defined for the actor control and the object control, respectively. The actor control and the object control will be described later with reference to FIGS. 25 to 27.

The information control system 100 is controlled by actors and objects, and features and specific methods will be described below.
(1) Separation of model logic and implementation cooperation ・ A range in which specifications are defined based on a model operates, and a part that requires cooperation with surroundings and operates.
-The interface between model logic and implementation linkage is realized only via data. In other words, procedures related to implementation cooperation are hidden by objects.

(2) Ensuring the independence of functions and the unit that operates when running is the unit of the actor, and is one unit for mounting. Note that “running out” means that it can be executed independently in that unit and “operates when a condition is met”.
・ Actors operate when the conditions they should operate are met.
• Actors do not implement synchronous execution with other actors during actor execution. That is, the logic is not such that an execution request is made to another actor and a response from the requested actor is waited for.
・ Execution is performed to verify whether or not all actors can be executed periodically, and the actions to be executed are sequentially executed (actor control).

(3) There is no data or status for the next time in the unit where logic and data can be separated and run. For things that run well, and values and states that need to be continued to run, another implementation that manages the values and states is performed.
(4) Ensuring independence of data units.
・ Data is defined by object. For this reason, the object linked with the outside updates the data of the other party based on the actor or the data update from the outside.
-Data updates for linking with the outside of the object are fetched before the actor execution cycle and reflected after execution. A function group for realizing this data update is defined in the object.

Defines the behavior model of actors and objects that satisfy the above characteristics. That is,
(1) The actual data is reflected in the object data before execution based on the actor control. Executes a function group that is specified for an object and that is executed when it is referenced.
(2) The actors are activated sequentially according to the execution order of the actors specified by the actor control. In particular,
(2-1) The actor determines whether the condition to be executed by the actor is satisfied.
(2-2) An actor that satisfies the conditions is executed based on the described specifications. Specifically, necessary data is referenced from the object, and data is set in the object according to a predetermined rule.
(2-3) When the execution of all actors is completed, the value of the object whose value has been changed is reflected in the actual data. Executes a function group that is specified in the object and that is executed when it is updated.

Next, specific actor definition tables and object definition tables will be described.
3 to 6 are actor definition tables, and FIGS. 7 and 8 are object definition tables. In this embodiment, an actor and an object that define an accident monitoring function of an electric station will be described.

  FIG. 3 is a block diagram showing the accident monitoring function of the actor definition table. The actor definition table includes a name part, a control part, and an execution part. The name part is composed of a name for identifying an actor, and has an actor type, an actor name 1, and an actor name 2. The control unit is a part that defines a monitoring item (object name) for the action of the actor and a start condition that is a condition for enabling the condition described in the execution unit.

  The execution unit (actor execution unit) includes a result including a monitoring item and a set value, and a condition for obtaining the result. The condition represents the operator's know-how reflected in the system to be controlled and the constraint conditions for operation (control). The execution unit defines conditional expressions in tabular form for a plurality of monitoring items. Specifically, if the [operation state] of [current] in [electricity station] satisfies the condition of [accident occurrence] by the processing unit 10, the [drawing pattern] of the monitoring item is instructed to [blink]. Means that. In cases other than the above (if [Operational State] in [Electric Power Station] does not satisfy the condition of [Accident Occurrence]), the [Drawing Pattern] monitoring item is commanded to [Blink Stop]. Means that. Furthermore, in the example shown in FIG. 3, if the [operation state] of [current] of [electricity station] satisfies the condition of [accident occurrence], the [drawing pattern] of the monitoring item is instructed to [blink] [Alarm] is commanded to [Output], and [Man Machine Button] is commanded to [Flicker].

  In the tabular execution unit, each term surrounded by “[” and “]” represents a definition word on the information control system 100. Hereinafter, each term surrounded by “[” and “]” is referred to as a “definition word”. This definition word is used as a definition word having a common meaning in other actors. This definition word is used to associate each actor.

  Also, as shown in FIG. 3, the information control system 100 needs to consider a time element, and therefore, a definition word such as [current] is used in the conditional expression. Since the time element is defined by other actors, the description is omitted.

  FIG. 4 is a configuration diagram showing an electric station state of the actor definition table. The actor definition table shown in FIG. 4 is the same as FIG. 3 and the description thereof is omitted, but the definition of OR conditions of a plurality of conditions is shown. Specifically, the monitoring item (object name) [Electric power station] is set to [Accident occurrence] in [Operation state] if a predetermined operation condition is satisfied. Predetermined operating conditions are those that [operating state] of [this time] for [belonging to electric station] and [bus] is [occurrence of accident], or [this] for [this time] for [belonging to electric station] and [railway] [Operating status] is [Accident occurred] condition, [Attached to electrical station] [Transformer] [Current] [Operating status] is [Accident occurred] condition, or [Attached to electrical station] [Power generation] This is a case where [Operating state] of [Current] of [Aircraft] satisfies the condition of [Accident occurrence]. Each [monitoring target] (for example, [belongs to an electric station] [bus]] is associated with the object definition table (equipment structure object) shown in FIG.

  FIG. 5 is a configuration diagram showing a bus accident state and a bus operating state of the actor definition table. The actor definition tables shown in FIGS. 5A and 5B are the same as those in FIG. 3 and will not be described. However, the conditions of the execution unit are AND conditions of a plurality of conditions. Specifically, as shown in FIG. 5A, the monitoring item (object name) [Bus] is a condition that [Accident monitoring status] of [Current] of [Bus] is [Monitoring], and If [Breaker State] of [Bus] satisfies the condition of [Trip], [Operating State] is set as [Accident Occurrence]. Similarly, [bus], which is the monitoring item (object name) shown in FIG. 5A, is a condition where [relay state] of [previous] of [bus] is [trip] and [current] of [bus] If [Relay status] of [] satisfies the condition of [Trip], [Accident monitoring status] is set to [Monitoring].

  Specifically, as shown in FIG. 5B, the monitoring item (object name) [bus] is [belongs to] and [relay] [previous] [state] is [connection]. [Relay status] is set to [Trip] if [Status] of [Current] of [Belonging] [Relay] is [Shutdown].

  FIG. 6 is a configuration diagram showing a relay state and a circuit breaker state of the actor definition table. The definition table shown in FIGS. 6A and 6B is a definition table that associates a signal bit (control signal) of an object that is one of the controlled systems with a “set value” of “monitor item”. It is. Specifically, as shown in FIG. 6A, the monitoring item (object name) [relay] is set to [connection] in the [state] when the condition is "0" and "1". Under the above conditions, [Status] is set to [Block]. Similarly, as shown in FIG. 6B, [breaker], which is a monitoring item (object name), is set to [connection] when [condition] is “0” and “1”. When the condition is met, [Status] is set to [Block]. The monitoring function unit 15 receives the control signal from the control target system 200 via the communication control unit 33.

  FIG. 7 is a configuration diagram showing an electric station of the object definition table. The object definition table includes an object definition table showing the equipment state shown in FIG. 7A and an object definition table showing the equipment structure shown in FIG. 7B. The object definition table has a common part for defining the attributes of the object and a data item part managed by the object.

  The common part includes an object name that identifies an object, a higher class that designates the class (group) of the object, and a class designation that designates whether or not the object is handled as a class. A class means an identifier of a group when grouped as a plurality of object groups.

  The data item section includes a data item name that is a name for identifying the data, a data format that specifies the data format of the data to be stored, a structure format of the meaning of the array when there are multiple data, and a value that can be taken by the data (status Value) that specifies a value), an initial value, and the like.

  Specifically, as shown in FIG. 7 (a), [drawing pattern], [operation state], etc. are specified in the data item part of the equipment state of the electric station, as shown in FIG. 7 (b). The data item part of the electrical facility equipment structure includes [belongs to electrical station] [bus], [belongs to electrical station] [track], [belongs to electrical station] [transformer], [belongs to electrical station] [Generator] is specified.

  FIG. 8 is a configuration diagram showing a bus of the object definition table. As in FIG. 7, the object definition table includes an object definition table indicating the equipment state shown in FIG. 8A and an object definition table showing the equipment structure shown in FIG. 8B. Specifically, as shown in FIG. 8 (a), [bus state], [accident monitoring state], [relay state], and [breaker state] are specified in the data item part of the equipment state of the bus. As shown in FIG. 8B, [belonging to the bus] [relay] and [belonging to the bus] [breaker] are specified in the data item portion of the equipment structure of the bus.

Next, the processing flow will be described.
FIG. 9 is a flowchart showing processing of the monitoring function unit. The monitoring function unit 15 of the processing unit 10 monitors the state of the actor set by the actor control setting unit 13. As shown in FIG. 2, even if a plurality of actors are registered as an actor group, each actor is basically independent and is a process of “operating when a condition is met”. FIG. 9 shows an actor process as a process of each monitoring function unit 15.

  The monitoring function unit 15 monitors the actor (step S1). The actor monitoring is to monitor whether or not the condition item of the actor has changed. If the state does not change (step S2, No), the process returns to step S1 to continue monitoring the actor. When the state has changed (step S2, Yes), it is determined whether or not the conditions for the actor are satisfied (step S3). If the actor condition is not satisfied (step S3, No), the process returns to step S1 to continue monitoring the actor. If the actor condition is satisfied (step S3, Yes), the set value of the monitoring item of the target object is set (step S4). Thereafter, the process returns to step S1 and continues.

  FIG. 10 is an explanatory diagram showing operations of a plurality of actors. The actor definition tables shown in FIGS. 3 to 6 are shown in FIGS. 10 (a) to 10 (e). 10 (a) shows the accident monitoring function, FIG. 10 (b) shows the electric station state, FIG. 10 (c) and FIG. 10 (d) show the bus state, and 10 (e) Indicates the relay status. In FIG. 10, only relevant definition words for explaining the association of a plurality of actors are shown, and other descriptions are omitted. In addition, the relationship between the definition words is described for the sake of explanation by a broken line or a solid line.

  When the monitoring function unit 15 receives the control signal (state value) “1” from the control target system 200 by the processing shown in FIG. 9, the monitoring function unit 15 performs the monitoring shown in FIG. Set [Status] of [Relay], which is an item (object name), to [Block]. Then, since the relay function shown in FIG. 5B satisfies the condition from the previous connection to the current disconnection, the monitoring function unit 15 selects [Relay] of [Bus] which is the monitoring item (object name) shown in FIG. Set [Status] to [Trip]. Furthermore, the monitoring function unit 15 sets [Monitoring] in [Accident monitoring state] of [Bus] which is a monitoring item (object name) shown in FIG. Furthermore, the monitoring function unit 15 sets [operation state] of [bus] that is a monitoring item (object name) shown in FIG. Furthermore, the monitoring function unit 15 sets [Operation status] of [Electric power station], which is the monitoring item (object name) shown in FIG. Next, the monitoring function unit 15 sets [drawing pattern] of [electricity station] which is the monitoring item (object name) shown in FIG. In this way, even if a plurality of actors are registered as actor groups, each actor is basically independent, and sequentially processes the process of operating when a condition is met. Finally, when the monitoring function unit 15 issues a control command to the control function unit 16, the control function unit 16 transmits a control signal to the object specified by the monitoring function unit 15, and performs control via the communication control unit 33. The target system 200 is controlled.

  For example, a command whose [drawing pattern] is [blink] shown in FIG. 3 shown in FIG. 3 is displayed on the display unit of the output unit 32 and is displayed on a control monitor (not shown) of the control panel of the control target system. A control command should be issued.

  In the present embodiment, the actor definition table (actor definition information) is shown in FIGS. 3 to 6, but this is an actor definition table that can be used in common as an actor in an electric station. Therefore, the actor definition table stored in the actor DB 21 may be registered in the dictionary DB 23 in advance by the administrator of the information control system 100 or the like. In this case, when the processing unit 10 accepts the dictionary registration request for the actor definition information, the processing unit 10 stores the actor definition information already stored in the actor DB 21 of the storage unit 20 in the dictionary DB 23 and accumulates it as a dictionary. If the object name of the object, the monitoring item of the object, and the setting value of the monitoring item are defined with reference to the actor definition information, the actor definition information in the dictionary DB 23 may be used.

Next, an actor definition table and an object definition table in the train operation management system will be described with reference to FIGS.
In FIGS. 11-24, the train approach monitoring in the station of a train operation management system and the monitoring of a main line traffic light state are demonstrated to an example. In the case of a train operation management system, objects include main line traffic lights, levers, track circuits, and the like. The lamp of the CTC control panel can also be said to be an object.

(Actor definition table (actor definition information))
FIG. 11 is a configuration diagram showing entrance control of the actor definition table. The actor definition table shown in FIG. 11 is the same as that shown in FIG. [CTC control information] is set to [Information present] if [Train approaching] of the instruction setting item name [Applicable signal belongs] [Station] [Train approaching] satisfies the condition of [Near approaching]. On the other hand, when the above condition is not satisfied, [CTC control information] is set to [previous value hold].

FIG. 12 is a configuration diagram showing a train approach check in the actor definition table. The actor definition table shown in FIG. 12 is the same as that in FIG. 3 and will not be described. However, the conditions of the execution unit are AND conditions of a plurality of conditions. Specifically, the control target item [for approach detection] [start circuit] [current] [falling state] is [falling] and [station] [current] [control target train] If “Presence / Absence” satisfies the condition “There is a control target train”, “Train approach” is set to “Now approaching”. If the above condition is not satisfied, [Train approach] is set to [Non-approaching].
In addition, the place where the brackets are blank ([]) is a place where the definition word may or may not be entered, and in this example, the definition word is not entered.

[Station], which is the control target item, is set to [With control target train] if [Station status] of [Station] satisfies the condition of [Normal]. Similarly, if the [station] which is the control target item satisfies the condition of [abnormal] in [station state] of [station], [presence of control target train] is set to [no control target train].

FIG. 14 is a configuration diagram showing a station state check of the actor definition table. The actor definition table shown in FIG. 14 is the same as that in FIG. 3 and will not be described. However, the conditions of the execution unit are AND conditions of a plurality of conditions. Specifically, the [station] that is a control target item has a [station] [current] [current state] [energized state] is [energized] condition, and [station] [current] [CTC state] is [ If the condition of “normal” is satisfied, “station state” is set to “normal”. Similarly, if [station] which is a control target item satisfies the following condition A, condition B or condition C, [station state] is set to [abnormal].
Condition A: [Current state] of [Station] [Current state] is [Energized], and [Current state] [CTC state] of [Station] is [Abnormal].
Condition B: [Electric state] of [Current] of [Station] is [Power failure], and [CTC state] of [Current] of [Station] is [Normal]
Condition C: [Current state] of [Station] [Current state] is [Power failure], and [CTC state] of [Current station] is [Abnormal].

In the equipment state object shown in FIG. 19, data items relating to the equipment structure of the station are designated. Specifically, [for approach detection] and [track circuit] are specified.

FIG. 20 is a configuration diagram showing an equipment structure object definition table of a main line traffic signal.
In the equipment state object shown in FIG. 20, data items related to the equipment structure of the main line traffic signal are specified. More specifically, [corresponding traffic signal configures the course] [track circuit], [corresponding traffic signal belongs] [station], [inverted holding lever], [line closing lever] is specified.

  FIG. 21 is an explanatory diagram showing operations of a plurality of actors. The actor definition tables shown in FIGS. 11 to 14 are shown in FIGS. 21 (a) to 21 (d). Fig. 21 (a) shows entrance control, Fig. 21 (b) shows train approach check, Fig. 21 (c) shows control target train determination, and Fig. 21 (d) shows station status check. Show. FIG. 21 shows only related definition words for explaining the association of a plurality of actors, and omits other descriptions. In addition, the relationship between the definition words is described for the sake of explanation by a broken line or a solid line.

  By the processing shown in FIG. 9, the monitoring function unit 15 monitors the power outage state or CTC state of the corresponding station. For example, the power outage state is “energized” and the CTC state is “normal”. When information is received from the control target system 200, the [station state] of [station], which is the monitoring item (object name) shown in FIG. 21 (d), is set to [normal] via the target object of the control signal. To do. Then, the monitoring function unit 15 sets [control train presence / absence] of [station] which is the monitoring item (object name) shown in FIG. Further, in addition to the condition of FIG. 21C, the monitoring function unit 15 sets the condition of “falling” of “starting circuit” to “falling” in addition to the condition of FIG. The [train approach] of [station] which is the monitoring item (object name) shown in FIG. Furthermore, the monitoring function unit 15 sets [CTC control information] of [main line traffic signal], which is the monitoring item (object name) shown in FIG. As described above, even if a plurality of actors are registered as a group of actors, each actor is basically independent, and is sequentially processed with a process of operating when a condition is satisfied. Finally, when the monitoring function unit 15 issues a control command to the control function unit 16, the control function unit 16 transmits a control signal to the object specified by the monitoring function unit 15, and performs control via the communication control unit 33. The target system 200 is controlled.

For example, the command with [information on] [CTC control information] shown in FIG. 11 shown in FIG. 11 is displayed on the display unit of the output unit 32 and a control monitor (not shown) of the control panel of the controlled system. ) Control command. Specifically, for example, when [CTC control information] is set to [information present], the monitoring function unit 15 turns on the lamp of the corresponding traffic light (object) on the CTC display panel, for example.
When [CTC control information] is [previous value hold], there is no change in the CTC display panel.
At this time, the monitoring function unit 15 refers to another actor definition table based on the information [CTC control information] shown in FIG. The traffic lights shown in FIG.

The definition tables shown in FIGS. 22 to 24 show more detailed definition tables than the definition tables shown in FIGS.
FIG. 22 is a configuration diagram showing an intermediate state of the main line traffic signal in the actor definition table, and FIG. 23 is a configuration diagram showing a main traffic signal status of the actor definition table. The actor definition tables shown in FIGS. 22 and 23 are the same as those in FIG. 3 and will not be described. The operation between the actors in FIGS. 22 and 23 is as follows.
For example, if [CTC Display Information] of [Current] of [Main Line Traffic Signal] is [No Information] (reference A1), the monitoring function unit 15 selects [Current Line Traffic Signal] of [Main Line Traffic Signal] which is a monitoring item (object name). Indication state] is set to [No indication information] (reference A2).
Here, the items A3 to A6 satisfy the condition that [present state] of [previous] of [main line traffic light] is [no present information]. The items A3 to A6 are ANDed with the items A7 to A10, and the monitoring function unit 15 selects [line light display (cancel all over)] of [main line traffic light] which is a monitoring item (object name). ] Is [Settings], [Main line traffic light] [Line light display (cancel all top)] is [Release], [Main line traffic light] [Line light display (cancel landing)] is [Setting], [Main line] [Release] etc. is set for [Line Light Display (Receiving Landing)] under [Signal].

In FIG. 22, when the [status] of [current] of [close line] is [one or more] [already set] (reference numeral B1), the monitoring function unit 15 displays the monitoring item (object name). [Line closed state] of a certain [main line traffic light] is set to [line closed] (reference B2).
Items in which [Line closed state] of [Main line traffic light] is set to [Line closed] are code B3 and code B4 in FIG. Since there is no other item that is an AND condition for the symbol B4, the monitoring function unit 15 monitors the monitoring item (object name) if [line closed state] of [current] of [main line traffic light] is [line closed]. [Status] of [Main line traffic light] is set to [Inversion control output during track closing] (reference D1).
Whether the item D2 is set for the symbol B3 depends on whether the item described in the symbol C3 is set.

Furthermore, in FIG. 22, when [CTC control information] of [Current] of [Main line traffic light] is [Information present] (reference C1), the monitoring function unit 15 is [Main line traffic light] which is a monitoring item (object name). ] [Control output request status] is set to [requested] (reference C2).
In this case, the items whose [control output request state] is [requested] in [current] with the condition [main traffic signal] are items C3 to C5 in FIG.
Since there is no other item that becomes an AND condition for the code C5, if the [control output request state] of [current] of [main line traffic light] is [requested], the monitoring function unit 15 selects the monitoring item (object name). ) [Main line traffic light] is set to [Inversion control output during inversion holding] (reference D4).
Regarding the items of code C3 and code C4, whether or not the items of code D3 and code D2 are set depends on whether the conditions of code B3 and code E1 are satisfied, respectively.

Here, the symbol B3 is an item set by the symbol B2 in FIG. 22 as described above.
That is, in the actor definition table of FIG. 22, the monitoring function unit 15 sets [Line closed state] of [Main line traffic signal] which is a monitoring item (object name) as [Line closed] (reference B2), and [Main line]. If [control output request status] and [requested] are set for [traffic signal] (reference C2), the monitoring function unit 15 selects [status of main line traffic signal] that is a monitoring item (object name) from the actor definition table of FIG. ] Is set to [Reverse control output request while line is closed] (reference D2), [State] of [Main line traffic light] is set to [Reverse control output while line is closed] (reference D1), Further, the [state] of [main line traffic light] is set to [reverse control output request while holding the reversal] (reference D4).

  As described above, according to the present embodiment, items determined by a plurality of conditions associated with each other in a complex manner can be set in a chained manner, and the object can be easily and reliably controlled.

FIG. 24 is a diagram showing another example in the object definition table.
FIG. 24 shows an equipment state object definition table of the main line traffic signal.
The structure of the object definition table in FIG. 24 is the same as in FIG. 7 and FIG. 8 and the like, and will not be described. However, as shown in FIG. 24, as the data item name of the data item, , [Display status], [Line light display (release all top)], [Line light display (cancel landing)], [Line closed status], [Control output request status], etc. are specified. Has been.
And the control content set to each data item name is set. For example, [Green], [White Blink], [Green Blink], and [Background] are set in [Drawing Pattern].

《Actor control definition ・ Object control definition》
Next, the actor control and the object control will be described with reference to FIGS.
The actor control is for controlling the execution of the actor. Specifically, the operation order of the actor is defined. For example, a plurality of actor controls are performed when the function of an object to be operated differs depending on the situation in which the information control system 100 is provided.
The object control is for making object values coincide in a plurality of information control systems 100.
Actors and objects are arbitrarily mounted on a plurality of information control systems 100. For this reason, it is necessary to match the values of the objects between the information control systems 100. The object control executes processing for matching object values between the information control systems 100.
The actor control and the object control define the operation by an actor control definition and an object control definition described later with reference to FIG.

FIG. 25 is a diagram showing a system configuration when performing actor control and object control.
25 is different from FIG. 1 in that a plurality of information control systems 100 are provided. Further, there is a control target system 200a that is connected to the external system 400 and operates in cooperation with the external system 400 (hereinafter referred to as “cooperation”). For example, the external system 400 is a system belonging to another electric power company if it is a power system, and the target route is a system related to another route if it is a train operation system.
Further, an actor control definition described later with reference to FIG. 26 is stored in the actor DB 21, and an object control definition described later with reference to FIG. 26 is stored in the object DB 22.

  FIG. 26 is a diagram showing an actor control definition (actor control definition information) and an object control definition (object control definition information). FIG. 26 (a) shows the structure of the actor control definition for parallel execution, FIG. 26 (b) shows the structure of the object control definition, and FIG. 26 (c) shows the object update information of the external unlinked type. FIG. 26 (d) shows the structure of externally linked object update information.

As shown in FIG. 26A, the actor control definition has “actor control ID”, “execution establishment condition”, “execution cycle”, and at least one actor group.
The “actor control ID” is an identification number uniquely assigned to the actor control definition. When executing the actor control, the monitoring function unit 15 specifies the actor control to be executed based on the “actor control ID”. The “execution fulfillment condition” is a fulfillment condition for executing the actor control defined by the actor control definition, and specifically, an object value condition for executing the actor control is registered. The “execution cycle” is a cycle in which the execution confirmation condition in the actor control definition is confirmed.
The actor group is a list of actor names.
Here, the actors not registered in the actor group are not executed even if the execution condition is satisfied.
This will be described with reference to FIG.

As shown in FIG. 27A, “Actor 1” to “Actor 10” are registered as “Actor Group A” and “Actor 101” to “Actor 110” are registered as “Actor Group B” in the actor control definition. Suppose that
Then, as shown in FIG. 27B, when the upper and lower actors are set, when the execution establishment condition and the execution cycle are established, the “actor group A” is executed first, followed by the “actor group A B "is executed. When “actor group A” is executed, “actor 1” is first executed by the monitoring function unit 15. An arrow in FIG. 27B indicates execution from the actor to the actor (similar to the arrows in FIG. 10 and FIG. 21). The fact that the actor is divided into two forks indicates the possibility that two higher-order actors are executed depending on the conditions of the lower-order actors. Here, a lower actor is an actor that is close to the first referenced actor when the value of the object is changed when focusing on two actors, and the upper actor is finally referenced. Actor that is close to the actor.

  As shown in FIG. 27 (b), even if the condition for executing "actor 11" is satisfied from the condition of "actor 2", "actor 11" is not registered in "actor group A". The monitoring function unit 15 does not execute the “actor 11”. Similarly, even if the condition for executing “actor 101” is satisfied from the condition of “actor 2”, “actor 101” is registered in “actor group B”, but “actor group A”. Since it is not registered, the monitoring function unit 15 does not execute the “actor 101”.

That is, in FIG. 26A, an actor that is not related to an actor registered as an execution target actor is not executed even if the execution establishment condition is satisfied. In other words, as will be described later, the items established in the conditions in the execution unit of the actor are set in a chain, but at this time, the actors not described in the execution target actor will be satisfied even if the conditions of the execution unit are satisfied. The corresponding item is not set.
A plurality of actors described in the execution target actor are executed.

  Note that either the execution establishment condition or the execution cycle can be omitted. When the execution establishment condition is omitted, the actor control is executed at a certain execution cycle. When the execution cycle is omitted, regardless of the cycle, when the execution establishment condition is satisfied, the lowest-order actor registered in the corresponding actor control definition is executed.

  In this case, since it does not belong to the actor group as shown in FIG. 27, there is no actor that is not referred to.

  Here, the actor name in FIG. 26A and the information of the name part (actor type, actor name 1, actor name 2) described in FIG. 3 are stored as a set.

Actors are executed based on the satisfaction of the conditions registered in the actor definition table, but since actors refer only to object values, execution conditions are determined only by changes in object values. Is done. Actor control uses this property. Rather than verifying the actor conditions each time, the actor's individual condition establishment status is stored as an execution establishment condition in the actor control definition. Only the information control system 100 monitors whether or not it is established.
Here, the object value is a set value of the object, and corresponds to “blink”, “blink stop”, etc. in FIG.

As shown in FIG. 26B, the object control definition has “object control ID” and “object update information”.
“Object control ID” is an identification number uniquely assigned to the object control definition. When executing the object control, the monitoring function unit 15 specifies the object control to be executed based on this “object control ID”. The “object update information” includes an external non-cooperation type as shown in FIG. 26C and an external cooperation type as shown in FIG. An externally linked object is an object that bridges an external system. That is, this object is an object of the control target system 200a of FIG.

  The “operating system priority information” shown in FIG. 26C indicates which information control system 100 is preferentially targeted for object control when a target object exists in a plurality of information control systems 100 (which information Information specifying whether to instruct the control system 100 to change the object value, specifically, an identifier of the information control system 100 is registered. When the operating system priority information is not registered, the monitoring function unit 15 that executes object control simultaneously executes object control to the target information control system 100 (instructs change of the object value). .

In the “synchronization target”, the name or identification number of the information control system 100 that is a target for matching object values in object control is registered.
In the “synchronization timing”, information defining at which timing synchronization (object control is executed) is registered. For example, information such as “synchronize at the same time as the corresponding object value is set” and “synchronize at a fixed period” is registered.
In “Handling at the time of mismatch”, information indicating which object value is given priority when an object value is changed simultaneously between the information control systems 100 is registered. For example, the priority order of the information control system 100 is registered, or information indicating “according to“ operating system priority information ”” is registered.

The “synchronization target” and “synchronization timing” in FIG. 26D are the same as the “synchronization target” and “synchronization timing” in FIG.
In the “method execution availability information”, information on whether or not this object executes a linkage method (method) to an external system to be linked is registered. For example, when the same method is registered in a plurality of information control systems 100, if all of the methods are operated, the entire system is linked with the external system and does not operate correctly. There is. Therefore, “method execution availability information” in the object control definition defines and sets which information control system 100 manages the object managed by the external system. Note that the “method execution availability information” can be omitted, and if omitted, the object managed by each information control system 100 cooperates with the external system that is the cooperation target.

  Although not shown in the object definition table described above, this is registered in the object definition table for objects that perform external cooperation. Whether the monitoring function unit 15 should refer to “external non-cooperation object update information” or “external cooperation object update information” is registered in the object definition table as information indicating that the object is to be externally linked. Judgment can be made by whether or not it is done.

"flowchart"
FIG. 28 is a flowchart showing processing of the monitoring function unit.
The monitoring function unit 15 determines whether or not there is an instruction to change the object value from another information control system 100 (step S101). This change instruction is an instruction transmitted by another information control system 100 according to the object control definition. If there is no change instruction (step S101, No), the process proceeds to step S103. If there is a change instruction (step S101, Yes), the monitoring function unit 15 updates the object value according to the transmitted change instruction (step S102).

  Next, the monitoring function unit 15 monitors information input from the input unit 31 and determines whether or not there is an input instruction such as an actor interrupt execution instruction (step S103). If there is no input instruction (No at Step S103), the process proceeds to Step S105. When there is an input instruction (step S103, Yes), the monitoring function unit 15 executes the corresponding actor (step S104). The content of step S104 is the content described above with reference to FIG. If there is an input instruction here, the actor corresponding to the input instruction is executed because the input instruction has priority over the content of the actor control definition.

  Next, when the current time is obtained from a timer (not shown), the monitoring function unit 15 refers to the execution cycle registered in the execution condition of each actor control definition and determines whether or not the current time is the execution time. (Step S105). If it is not the execution time (step S105, No), the process returns to step S101 and the process is continued. When it is an execution time (step S105, Yes), the monitoring function part 15 performs the following processes. The monitoring function unit 15 monitors the change of each object input from the control target system 200 and stores the monitoring result. The monitoring result stores the value of the object whose value has changed and the definition word in the actor definition table in association with each other. Then, the monitoring function unit 15 refers to the monitoring result and the actor control definition, and determines whether or not the execution establishment condition registered in the actor control definition is satisfied (step S106). If the execution satisfaction condition is not satisfied (No at Step S106), the process proceeds to Step S108. If the execution satisfaction condition is satisfied (step S106, Yes), the monitoring function unit 15 executes the actor according to the corresponding actor control definition (S107). The execution of the actor is as described in FIG. 10 and FIG.

  Here, by verifying whether or not the execution satisfaction condition described in the actor control definition is satisfied, the monitoring function unit 15 does not need to search the execution conditions described in all the actor definition tables. That is, since the monitoring function unit 15 only needs to search for the execution condition for the actor control definition, it is possible to improve the processing efficiency.

  Next, the monitoring function unit 15 searches the object control definition and determines whether or not the updated object value is the object control target as a result of the execution of the actor in step S107 (step S108). If it is not the object of object control (No at Step S108), the process returns to Step S101. When the object is a target of object control (step S108, Yes), the monitoring function unit 15 determines whether or not the synchronization timing registered in the object control definition is established (step S109). If the synchronization timing is not established (No at Step S109), the process returns to Step S109 and waits until the synchronization timing is established. When the synchronization timing is established (step S109, Yes), the monitoring function unit 15 instructs the other information control system 100 to change the object value according to the object control definition (step S110). The instruction target in step S110 is the information control system 100 registered in the object control definition synchronization target. The monitoring function unit 15 registers the updated object value in the update history information of the object value (not shown).

  A plurality of actor controls can be defined in one information control system 100, but these actor controls are not executed simultaneously. In other words, when this actor control is executed when the execution establishment condition of a certain actor control definition is established, even if the execution establishment condition is established for other actor controls, until the currently executing actor control is completed, Other actor controls await execution.

  Note that if the “execution establishment condition” is omitted in the object control definition, step S106 is omitted, and if the “execution cycle” is omitted, step S105 is omitted.

  In the present embodiment, examples of the power system and the train operation system have been described for the actor definition table and the object definition table, but the present invention is not limited to this. Any control target system that can be defined as an actor and an object can be used in other information control systems such as a water and sewage management system.

According to this embodiment, it also has the following effects.
(1) By verifying whether or not the execution condition described in the actor control definition is satisfied, the monitoring function unit 15 does not have to search for the satisfied condition described in all the actor definition tables. That is, the monitoring function unit 15 only needs to search for the execution condition of the actor control definition, so that the processing efficiency can be improved.
(2) Since only the actor described in the actor control definition is executed when the execution condition is satisfied, it is possible to prevent an unintended actor from being executed.
(3) When the intended actor is not executed, or when an unintended actor is executed, the actor definition table described in the actor control definition corresponding to the corresponding execution condition can be checked, so the action that the actor does not intend Elucidation of the cause when performing
(4) By defining the object control, it is possible to unify the object values among the information control systems 100.

  In the present embodiment, examples of the power system and the train operation system have been described for the actor definition table and the object definition table, but the present invention is not limited to this. Any control target system that can be defined as an actor and an object can be used in other information control systems such as a water and sewage management system.
