Description

  The present invention relates to a process flow starting from a specific electrical signal in an operation of planning or examining a configuration of a control system by integrated control (hereinafter referred to as an integrated control system) that executes a plurality of control units in an integrated manner. Then, it is related with the control interference candidate detection apparatus and control interference candidate detection method for notifying a designer of the location (henceforth a control interference candidate) which may generate the contradictory command signal.

Currently, in the work of planning or examining the configuration of an integrated control system, the flow of signals is often verified after creating a connection diagram of devices to be controlled (unit units or unit parts constituting the devices).
In addition, when using control by software, there are a method of adding and verifying a software processing outline and a method of separately preparing and verifying a software processing flow diagram.

  Although it is possible to model each control and simulate the signal flow, at the present time, it takes time to make a large-scale model, and there is no means to prevent omission of consideration of the designer at the time of modeling. .

  In particular, in recent years, various devices distributed in the market are controlled not only by machine parts but also by software. When the device to be controlled becomes complicated, the integrated control system also becomes complicated, and the control for the same event may become inconsistent.

  For example, in the case of a car, a car navigation system (hereinafter referred to as a car navigation system) detects that a running car has reached a curve, and a speed control unit and power steering (hereinafter referred to as a power steering) A control signal is output to the control unit. Based on this control signal, the speed control unit outputs a control signal for lowering the engine output to the engine output control unit in order to reduce the speed of the automobile. In contrast, the power steering control unit outputs a control signal for increasing the output of the engine to the engine output control unit in preparation for the steering operation.

  As described above, in the control of the automobile, there is a case where the control for the same event such as the request signal for increasing the engine speed and the request signal for decreasing the engine speed are contradictory.

  On the other hand, if the control program is created as the same module or runs in the same hardware, it is possible to check for inconsistencies in the control based on the overall software design document. In the case where the scale is large and distributed control is performed by a plurality of hardware, it is not easy to detect a problematic part (control interference candidate).

  In addition, the conventional control program analysis apparatus includes a control flow relation data collection apparatus that collects relation data regarding the flow of program elements, and a control flow net generation that creates a control flow net diagram from data collected by the control flow relation data collection apparatus. A data flow relationship collection device that collects a data flow relationship from another device relationship separated from the program elements, and a control flow net generation device from the contents of the data flow relationship collection device. That is, the conventional control program analysis apparatus analyzes a control program, and in addition to a control flow net diagram showing the flow of the control program, a data flow net diagram showing which process (instruction) data is used and changed by (See, for example, Patent Document 1).

In addition, the conventional software development support system includes a device that describes a device name, an attribute, and a failure pattern that may occur, a carrier that is transmitted between the devices, a device diagram that indicates a relationship between the devices, and a device. When an information flow diagram consisting of a process diagram indicating the process to be processed and the process conditions and an arrow indicating the relationship between the device diagram and the process diagram is input, the analysis function in the processing unit The unit obtains a failure in the function of the embedded system by referring to the information flow diagram, and performs a process of presenting a scenario based on the failure as information for determining software specifications via an output unit such as a display device. In other words, the conventional software development support system diagrammatically illustrates the connection diagram of the integrated control system (device and signal), and temporarily sets the case where a specific device fails (ie, the output signal is fixed). Analyzing the flow and verifying whether the corresponding processing is included or not, detects a case where the control system transitions and returns to the same device regardless of signal fixation (for example, Patent Document 2) reference).

  However, the conventional control program analysis apparatus does not disclose means for actually specifying a location (control interference candidate) where a mismatch occurs in the configuration of the designed integrated control system. For this reason, after the connection diagram of the integrated control system is diagrammed, it is necessary for the designer to visually verify the diagrammatic connection diagram of the integrated control system. That is, in a complicated integrated control system composed of a large number of controls, it is difficult to check the signal flow without omission, and there is a problem that verification takes a long time.

  The conventional software development support system checks whether signal processing for a failure (abnormal event) is incorporated in the control when the configuration of the integrated control system is normal. It is assumed that the inspection for the configuration has been completed. That is, it does not detect signal collision (interference) in the designed integrated control system configuration.

  The present invention has been made in order to solve the above-described problems, and can detect a combination of controls that cause inconsistency from the entire integrated control system. The control interference candidate detection apparatus and the control interference candidate detection method can be provided, which can efficiently perform discovery and prevent detection failure by the designer.

The control interference candidate detection apparatus corresponds to signal identification information that is information for identifying an input signal and / or an output signal for each component of the integrated control system, with component identification information that is information for identifying each component. A component type creating means for creating a list of component items attached, and a signal type indicating the type of signal by identifying the signal identification information of one input signal or one output signal in each component identification information based on the component list Corresponding with information, the same identification information is associated with each signal identification information of a plurality of input signals and output signals having the same signal identification information, and each of the plurality of input signals and output signals having different signal identification information Based on the component relationship table, the component relationship table creation means for creating a component relationship table in which different identification information is associated with the identification information, The same identification information associated with each signal identification information of a plurality of output signals having the same number identification information is extracted, and the component element is started from the signal identification information of the input signal corresponding to the extracted identification information. Based on the relationship table, corresponding component identification information and signal identification information of the input signal are sequentially detected, and a detection signal list including the signal identification information of the detected input signal and a detection component list including the component identification information are created. And an interference candidate list creation means .

  In the following description, in order to facilitate understanding of the present invention, an integrated control system that is a detection target of a control interference candidate by the control interference candidate detection system 100 according to the present embodiment (hereinafter referred to as a target integrated control system). As an example, a control configuration for controlling the output of an automobile engine will be described.

  For example, as shown in FIG. 7, the target integrated control system includes a speed control unit including constant speed traveling control, a power steering control unit, a light control unit for directing light in a curve direction, and a light direction control unit. The speed control unit controls the speed of the automobile by the engine output control unit. In particular, an automobile equipped with a car navigation system is assumed to incorporate a curve detection control unit as control for utilizing information approaching a curve. The actual vehicle control is a complicated system including shift control, but the illustration and description are omitted for the sake of simplicity.

Here, when the target integrated control system shown in FIG. 7 detects that the car navigation system has approached the curve and issues a control signal, first, the speed control unit performs control to reduce the speed in advance. Can be considered. It is also conceivable that the power steering control unit performs control to output power from the engine to the steering in order to reduce the burden of steering operation.
That is, it can be seen that the engine output control unit has a control configuration in which a request to lower the output and a request to increase the output can be given.

  Hereinafter, in the present embodiment, the control interference candidate detection system 100 that allows a designer to automatically detect a control interference candidate instead of visually detecting a control interference candidate in the block diagram of the target integrated control system. explain. Note that the target integrated control system is not limited to the engine output control of the automobile, and the control interference candidate detection system 100 according to the present embodiment can be used even for control of household electric appliances and the like.

  The integrated control system includes components such as a sensor, a switch (SW), a control unit that applies an appropriate operation to keep a machine or a device in a target state, or a drive unit that moves with power, and a plurality of components. The main configuration is wiring for transmitting signals between elements.

  Information representing the integrated control system includes component element identification information that is information for identifying each component element (in this case, information relating to the name of the component element), and information that identifies an input signal that is input to each component element (Input). Here, input signal identification information which is information on the name of the input signal), and output signal identification information which is information (here, information on the name of the output signal) that identifies the output signal output from each component Is included. In particular, the input signal identification information and the output signal identification information are collectively referred to as signal identification information.

  In FIG. 1, component element information 21 is information in which information representing the entire integrated control system is decomposed and input signals and output signals are defined for each component element with reference to component element identification information.

  For example, as shown in FIG. 2, the component element information 21 includes “constant speed control On / Off” and “first approach signal” as input signal identification information if the component identification information is “speed control unit”. And “second travel speed” are associated with each other, and “first output instruction” is associated with the output signal identification information as a table.

  The control interference candidate detection device 10 receives the component element information 21 and the selection information from the input device 30, detects a control interference candidate for the target integrated control system, and outputs the detection result to the output device 40.

The multiple input stage detection means 5 detects a stage (hereinafter referred to as a multiple input stage) in which one signal is input in parallel to a plurality of control units in the target integrated control system. In addition, as shown in FIG. 3A, in the multiple input stage, the output signal from the component A is transmitted from the control unit B ₁ , the control unit B ₂ ,..., The control unit B _m (m> = 2). Is a part of the target integrated control system that is input to each of the plurality of control units.

The single output stage detection means 4 detects a stage (hereinafter referred to as a single output stage) in which signals output from a plurality of control units are input to a single control unit in the target integrated control system. As shown in FIG. 3A, the single output stage includes a plurality of control units including a control unit C ₁ , a control unit C ₂ ,..., A control unit C _n (n> = 2). Is a part of the target integrated control system that is input to the single control unit D.

The interference candidate detection means 6 detects a route to a single control unit in a single output stage based on a single signal in a plurality of input stages as an interference candidate. That is, in the target integrated control system, when a plurality of input stages are detected on the upstream side and a single output stage is detected on the downstream side, the starting component in the plurality of input stages, the plurality of input stages and the single output stage ( Signals between components in another stage (including other stages when a plurality of input stages and a single output stage are interposed) are detected as control interference candidates.
The control means 7 outputs the control interference candidate detected by the multiple input stage detection means 5, the single output stage detection means 4 and the interference candidate detection means 6 to the output device 40 as a detection result.

  In addition, based on the component information 21, the detection result of the control interference candidate is displayed on the display by creating a block diagram in which the direction of the signal between the components is indicated by an arrow (see FIG. 7). Then, the corresponding input signal and output signal arrows and component blocks in the block diagram are changed to the input signal and output signal arrows and component blocks which are not applicable, and the color, line width, line type, or combination thereof is changed. By changing the display (see FIG. 8), the position of the control interference candidate can be easily specified.

  The output device 40 is a display, a printer, or the like, and is an output means for outputting a detection result in a control interference candidate detection process described later. In the present embodiment, a display is used as the output device 40, but the output device 40 is not limited to the display.

Next, a processing procedure performed by the control interference candidate detection system 100 according to the present embodiment will be described with reference to FIGS. 4 to 6.
First, the operator of the control interference candidate detection system 100 uses the mouse or keyboard that is the input device 30 to select components necessary for configuring the target integrated control system. Thereby, the calculating means 9 acquires the component element information 21 (step S101).

The computing means 9 extracts one component identification information for which no input signal identification information exists from the obtained component information 21 (step S102).
Then, the calculation means 9 determines whether or not there are a plurality of output signal identification information associated with the extracted component identification information (step S103).

  If it is determined in step S103 that there are a plurality of output signal identification information associated with one component identification information, the plurality of output signal identification information is associated with the same component identification information. An identification code consisting of a common identification code indicating that the output signal is identified and an identification code for distinguishing between the plurality of output signal identification information, and an input signal identification common to the output signal identification information to which the identification code is assigned The same identification code is assigned to the information (step S104). For example, the output signal identification information of the component identification information “speed sensor” is “first traveling speed”, “second traveling speed”, and “third traveling speed”, and “c ”And“ 1 ”,“ 2 ”, or“ 3 ”as identification codes for distinguishing between the plurality of output signal identification information. In particular, the identification code “c1” of the output signal identification information “first traveling speed” is the identification code “c1” of the input signal identification information “first traveling speed” of the component identification information “curve detection control unit”. is there.

  If it is determined in step S103 that there is not a plurality of output signal identification information associated with one component identification information, a single identification code is assigned and an output signal identification is given the identification code. The same identification code is assigned to the input signal identification information common to the information (step S105), and the process proceeds to step S106 described later. For example, the output signal identification information of the component identification information “constant speed SW” is “constant speed control On / Off”, and “a” is given as a single identification code. In particular, the identification code “a” of the output signal identification information “constant speed control On / Off” is the identification code “a” of the input signal identification information “constant speed control On / Off” of the component identification information “speed controller”. But there is.

The calculating means 9 determines whether or not an identification code has been assigned to all output signal identification information associated with the component identification information extracted in step S102 (step S106).
If it is determined in step S106 that no identification code is given, the process returns to step S104.

If it is determined in step S106 that an identification code has been assigned, has the calculation means 9 given the identification code to the output signal identification information corresponding to all the component identification information for which no input signal identification information exists? It is determined whether or not (step S107).
If it is determined in step S107 that no identification code has been assigned, the process returns to step S102.

  If it is determined in step S107 that the identification code has been assigned, the calculation means 9 is one component in which identification codes are assigned to all input signal identification information among the non-selected component identification information. It is determined whether or not the identification information exists (step S108).

  If it is determined in step S108 that the component element identification information does not exist, the target integrated control system is incomplete, so the process returns to step S101 to acquire new component element identification information.

If it is determined in step S108 that the component identification information exists, the computing means 9 identifies one component identification in which identification codes are assigned to all input signal identification information among the non-selected component identification information. Information is extracted (step S109).
The computing means 9 determines whether or not there are a plurality of output signal identification information associated with the component identification information (step S110).

  If it is determined in step S110 that there are a plurality of output signal identification information, the identification associated with the identification code of the input signal identification information associated with the component identification information for the plurality of output signal identification information An identification code consisting of a code and an identification code for distinguishing between the plurality of output signal identification information is assigned, and the same identification code is assigned to the input signal identification information common to the output signal identification information to which the identification code is assigned. (Step S111). For example, in the component identification information “curve detection control unit”, the identification codes of the input signal identification information “position” and “first travel speed” are “b” and “c1”, respectively. “B + c1” is assigned as the identification code associated with the code, and “1”, “2”, or “3” is assigned as the identification code for distinguishing between the plurality of output signal identification information.

  In step S110, if it is determined that there are not a plurality of output signal identification information, the identification code of the input signal identification information associated with the component identification information is associated with the plurality of output signal identification information. In addition to assigning the associated identification code, the same identification code is assigned to the input signal identification information common to the output signal identification information to which the identification code is assigned (step S112), and the process proceeds to step S113 described later. For example, in the component identification information “speed control unit”, the identification codes of the input signal identification information “constant speed On / Off”, “second traveling speed”, and “first approach signal” are “a”, “ c2 ”and“ (b + c1) 1 ”, and“ a + c2 + (b + c1) 1 ”is assigned to the output signal identification information“ first output instruction ”as the identification code associated with the identification code of the input signal identification information. In particular, the identification code “a + c2 + (b + c1) 1” of the output signal identification information “first output instruction” identifies the input signal identification information “first output instruction” of the component identification information “engine output control unit”. It is also the code “a + c2 + (b + c1) 1”.

The calculating means 9 determines whether or not an identification code has been assigned to all output signal identification information associated with the component identification information extracted in step S109 (step S113).
If it is determined in step S113 that no identification code is given, the process returns to step S111.

If it is determined in step S113 that the identification code has been assigned, the computing means 9 determines whether or not the identification code has been assigned to the output signal identification information corresponding to all the component element identification information (step S113). S114).
If it is determined in step S114 that no identification code is given, the process returns to step S109.

  If it is determined in step S114 that an identification code has been assigned, the multiple input stage detection means 5 identifies the component identification information associated with the multiple output signal identification information and the identification code of the output signal identification information. Is detected (step S115).

  In the target integrated control system shown in FIG. 7, “speed sensor”, “steering angle sensor”, and “curve detection control unit” are detected as corresponding component identification information. Further, “c1”, “c2” and “c3” are detected as the identification codes of the output signal identification information associated with the component identification information “speed sensor”. Further, “d1” and “d2” are detected as the identification codes of the output signal identification information associated with the component identification information “steering angle sensor”. Furthermore, “(b + c1) 1”, “(b + c1) 2”, and “(b + c1)” are identification codes of output signal identification information associated with the component identification information “curve detection control unit”. 3 "will be detected.

  Further, the single output stage detection means 4 detects the component element identification information associated with the plurality of input signal identification information and the identification code of the output signal identification information (step S116).

  In the target integrated control system shown in FIG. 7, “curve detection control unit”, “speed control unit”, “power steering control unit”, “light control unit”, and “engine output control” are included as corresponding component identification information. Part "is detected. In addition, as identification codes of output signal identification information associated with the component identification information “curve detection control unit”, “(b + c1) 1”, “(b + c1) 2”, and “(b + c1)” 3 "will be detected. Further, “a + c2 + (b + c1) 1” is detected as the identification code of the output signal identification information associated with the component identification information “speed control unit”. Furthermore, “(b + c1) 2 + c3 + d1” is detected as the identification code of the output signal identification information associated with the component identification information “power steering control unit”. Further, “a + c2 + (b + c1) 1” and “(b + c1) 2 + c3 + d1” are used as the identification codes of the output signal identification information associated with the component identification information “engine output control unit”. Will be detected.

  The interference candidate detection means 6 is an identification code of the output signal identification information detected in step S115, and at least two output signals among the plurality of output signal identification information associated with one component identification information. Whether or not the identification code of the identification information is the identification code of the output signal identification information detected in step S116 and is included in the identification code of the single output signal identification information associated with one component identification information Is determined (step S117). In the target integrated control system shown in FIG. 7, it is determined that (b + c1) and c are included.

If it is determined in step S117 that it is not included, it means that there is no control interference candidate, and the process ends.
If it is determined in step S117 that it is included, the interference candidate detecting means 6 starts with the component element identification information associated with the output signal identification information to which the included identification code is assigned, The start end and end, and the start and end associated with the start code and end code by the identification code, with the end of the component identification information associated with the output signal identification information to which the identification code including the identification code is assigned A control interference candidate consisting of identification information and signal information identification information is detected (step S118).

  In the target integrated control system shown in FIG. 7, the “speed sensor” and the “curve detection control unit” are detected as the start ends, and the “engine control unit” is detected as the end points. The component identification information associated with the start and end by the identification code is “curve detection control unit”, “speed control unit”, and “power steering control unit”, and the signal information identification information is “first running speed” ”,“ Second travel speed ”,“ third travel speed ”,“ first approach signal ”,“ second approach signal ”,“ first output instruction ”, and“ second output instruction ”. is there.

  And with respect to the block diagram of the target integrated control system displayed on the display which is the output device 40, among the control interference candidates detected in step S115, the block of the component corresponding to the component identification information that is the starting end is displayed. While emphasizing, the arrow corresponding to input signal identification information is emphasized, and a control interference candidate is displayed on a display (step S119). Then, the process ends.

(Second embodiment of the present invention)
FIG. 9 is a block diagram illustrating a schematic configuration of the control interference candidate detection system according to the present embodiment, and FIG. 10A illustrates a definition example of a component unit stored in the component information table according to the present embodiment. FIG. 10B is an explanatory diagram for explaining a definition example of a control group stored in the control group information table according to the present embodiment, and FIG. 11 is an example of a component list according to the present embodiment. FIG. 12 is an explanatory diagram for explaining an example of a component relationship table according to the present embodiment, FIG. 13 is an explanatory diagram for explaining an example of a detection signal list according to the present embodiment, 14 is an explanatory diagram for explaining an example of the detection component list according to the present embodiment, FIG. 15 is a flowchart showing a processing procedure by the control interference candidate detection system shown in FIG. 1, and FIG. 16 is a flowchart shown in FIG. FIG. 17 is a block diagram showing an example of the target integrated control system, and FIG. 18 is a block diagram of the target integrated control system shown in FIG. 17 for explaining an example of a state where control interference candidates are displayed. It is explanatory drawing of. 9 to 18, the same reference numerals as those in FIGS. 1 to 8 denote the same or corresponding parts, and the description thereof is omitted.

  In FIG. 9, the component information 20 is an input signal for calculating one output signal by decomposing information representing the entire integrated control system on the basis of the input signal identification information and the output signal identification information. Information defined for each.

  That is, the correspondence of M (M> = 0) input signal identification information is organized into data for one component identification information and 1 (or 0) output signal identification information. Note that the number of pieces of input signal identification information is zero because there is no input signal and only an output signal exists for a component (for example, a sensor or SW) that is a starting point for transmitting a control signal. In addition, since there is no output signal and only an input signal exists for a component (for example, a drive unit) that is a terminal to which a control signal is transmitted, the number of output signal identification information is zero. In addition, you may decompose | disassemble in the unit of input / output as an internal signal of a component irrespective of the presence or absence of the input / output from the exterior of a component.

  For example, as illustrated in FIG. 10A, the component element information 20 includes “constant speed control On / Off” and “approach signal” as input signal identification information if the component identification information is “speed control unit”. And the “traveling speed” are associated with each other, and the “output instruction” is associated with the output signal identification information as a table. In addition, although the case where the component element identification information is the “speed control unit” has been described, the input signal identification information and the output signal identification information are similarly supported for the other component element identification information configuring the integrated control system. The attached component information exists and is stored in the component information table 20a.

  Here, in processing to be described later by the control interference candidate detection system 100 for the target integrated control system, the operator of the control interference candidate detection system 100 obtains necessary component identification information from the component information table 20a, such as a mouse or a keyboard. The selection is made by the input device 30. In this case, if a large-scale system (consisting of a large number of components) is targeted as the target integrated control system, a large selection operation is required.

  On the other hand, among the control units that constitute the target integrated control system, if certain control is performed by a plurality of control units, the component identification information of the plurality of control units is associated with the control group identification information and grouped. It is also possible to convert it into data. Here, the control group identification information is information for identifying the control group (here, information related to the name of the control group).

  In this case, as shown in FIG. 10B, for example, if the control group identification information is “engine control”, the component information 20 includes “speed control unit” and “engine output control” as the component identification information. The control group information table 20b is a table in which “parts” are associated with each other. In addition, although the case where the control group identification information is “engine control” has been described, if there is another control group that performs constant control by a plurality of control units, the control group identification information Similarly, there is control group information in which component identification information of a plurality of control units is associated, and is stored in the control group information table 20b.

  As described above, when one control group identification information is selected by grouping the component identification information of the plurality of control units in association with the control group identification information, the component identification information of the plurality of control units is selected. be able to. For this reason, it is possible to easily select all of the target components (decreasing the number of selections), and to improve the operability of the control interference candidate detection system 100.

  The component list creation unit 1 reads the component element information 20 corresponding to the component selected by the operator using the input device 30 from the component element information table 20a and the control group information table 20b, and each component of the target integrated control system. The component list 1a in which the signal identification information for is associated with the component identification information is created on the storage means 8 which is a memory.

  In the component list 1a, for example, each identification information is associated with the target integrated control system illustrated in FIG. 17 as illustrated in FIG. That is, in the component list 1a, M (M> = 0) input signal identification information is associated with one component identification information and 1 (or 0) output signal identification information. .

  Based on the component list 1a, the component relationship table creating unit 2 sets the signal identification information of one input signal or one output signal as the component identification information of each component, and the signal type (here, input or output). In correspondence with signal type information indicating In / Out), the same identification information (here, signal number) is associated with each signal identification information of a plurality of input signals and output signals having the same signal identification information, A component relationship table 2a is created on the storage means 8 in which different identification information (signal numbers) is associated with each signal identification information of a plurality of input signals and output signals having different identification information.

  In the component relationship table 2a, for example, each identification information is associated with the target integrated control system illustrated in FIG. 17 as illustrated in FIG. That is, in the component relationship table 2a, the input signal identification information and the output signal identification information in different columns in the component list 1a shown in FIG. 11 are rearranged so as to be in the same column. Further, the same signal number is assigned to the same signal identification information among the input signal identification information and the output signal identification information in the same column, and different signal numbers are assigned to different signal identification information.

  The interference candidate list creation means 3 extracts the same identification information associated with each signal identification information of a plurality of output signals having the same signal identification information based on the component relation table 2a, and extracts the extracted identification information. The component identification information of the corresponding component and the input signal identification information of the input signal are sequentially detected based on the component relationship table 2a, starting from the signal identification information of the input signal corresponding to the input signal, and the input signal of the detected input signal A detection signal list 3a composed of identification information and a detection component list 3b composed of component identification information of the component are created on the storage means 8.

  The single output stage detection means 4 has been described in the first embodiment. In particular, in the present embodiment, the signal identification information of the input signal that is the starting point of the signal identification information in the detection signal list 3a, the detection Of the component identification information in the component list 3b, the component identification information associated with the signal identification information of the input signal that is the starting point, and the input signal that is the starting point of the component element identification information in the component relationship table 2a A stage composed of the component identification information associated with the signal identification information is detected and output to the interference candidate detection means 6.

  The multiple input stage detection means 5 has been described in the first embodiment. In particular, in the present embodiment, the signal of the input signal detected redundantly in the signal identification information of the input signal of the detection signal list 3a. Among the identification information, the component identification information associated with the signal identification information of the input signal detected in duplicate among the component identification information of the detected component list 3b, and the component identification information of the component relationship table 2a A stage composed of the component identification information associated with the signal identification information of the input signal detected in duplicate is detected and output to the interference candidate detection means 6.

  The interference candidate detection means 6 has been described in the first embodiment. In particular, in this embodiment, the stage detected by the single output stage detection means 4 and the multiple input stage detection means 5 are detected. The interference candidate is detected based on the stage and the detection signal list 3a and the detection component list 3b.

  The control means 7 has been described in the first embodiment. In particular, in this embodiment, the control interference candidate is based on the detection signal list 3a and the detection component list 3b created by the interference candidate list creation means 3. Is output to the output device 40.

  Although the detection result of the control interference candidate may be output as a table as shown in FIGS. 13C and 14C, the direction of the signal between the components based on the component relationship table 2a. A block diagram indicated by an arrow is created and displayed on the display (see FIG. 17). Then, based on the detection signal list 3a and the detection component list 3b, the corresponding input signal and output signal arrows and component blocks in the block diagram are changed to the non-applicable input signal and output signal arrows and component blocks. Thus, it is preferable to display by changing the color, line width, line type, or combination thereof (see FIG. 18), because the position of the control interference candidate can be easily specified.

Next, a processing procedure performed by the control interference candidate detection system 100 according to the present embodiment will be described with reference to FIGS. 15 and 16.
First, the operator of the control interference candidate detection system 100 uses a mouse or keyboard that is the input device 30 to select a component or a control group necessary for configuring the target integrated control system. Thereby, the component list creation means 1 acquires the component group identification information from the component element information table 20a or the control group identification information from the control group information table 20b (step S1).

The component list creation unit 1 determines whether or not there is a control group designation (acquisition of control group identification information) (step S2).
If it is determined in step S2 that a control group has been designated, the component list creation unit 1 determines from the control group information table 20b (see FIG. 10B) based on the designated control group identification information. Component identification information associated with the control group identification information is acquired (step S3).

  Based on the acquired component element identification information, the component element list creating means 1 reads input signal identification information and output signal identification associated with the component element identification information from the component element information table 20a (see FIG. 10A). Information is acquired and stored in the component list 1a (step S4).

If it is determined in step S2 that no control group has been designated, the process proceeds to step S4. Then, the component list creation unit 1 acquires the input signal identification information and the output signal identification information associated with the component element identification information from the component element information table 20a based on the component element identification information acquired in step S1. And stored in the component list 1a.
And it is judged whether selection of a component or a control group was completed (Step S5).

  If it is determined in step S5 that the selection of the component or control group has not been completed, the process returns to step S1.

  If it is determined in step S5 that the selection of the constituent element or the control group has been completed, it means that the constituent element list 1a (see FIG. 11) has been created, and the constituent element relation information creating process starts.

  First, the constituent element relationship table creating unit 2 acquires a series of constituent element identification information, input signal identification information, and output signal identification information from the constituent element list 1a (step S6).

The component relationship table creating means 2 is configured to generate component identification information and signal identification information (input signal identification information or output signal identification information) based on the series of acquired component identification information, input signal identification information, and output signal identification information. Are stored in the component relationship table 2a as a set (one line in FIG. 12) together with signal type information (IO information) indicating the signal type (In / Out) (step S7).
Then, the component relationship table creating unit 2 acquires the signal identification information on the Nth row in the component relationship table 2a (step S8).

  Further, the component relationship table creating unit 2 determines whether or not it is the same as the signal identification information described above (step S9). It should be noted that the above-mentioned signal identification information means that in the component relationship table 2a shown in FIG. 12, the component relationship table creation means 2 is the first row, the second row,. When the signal identification information is acquired in order from the top, the signal identification information is acquired from the first row to the (N-1) th row.

If it is determined in step S9 that the information is the same as the previous signal identification information, the component relationship table creating unit 2 identifies the identification information (signal number) associated with the same signal identification information. Is set in the component relationship table 2a (step S10). For example, in the component relationship table 2a shown in FIG. 12, since the signal identification information “position” in the sixth row is the same as the signal identification information “position” in the second row, the second row The identification information “2” associated with the signal identification information “position” of the eye is set, and “2” is set as the identification information of the sixth row.
Then, the component relationship table creating unit 2 determines whether or not the identification information (signal number) has been set for all rows (step S11).

  If it is determined in step S11 that identification information has not been set for all rows, the process returns to step S8.

If it is determined in step S11 that the identification information (signal number) has been set for all rows, this means that the component relationship table 2a (see FIG. 12) has been created, and control is performed. The interference candidate detection process is started.
Here, when the input is insufficient to obtain the necessary output in the component, the signal shortage can be detected at this stage.

  Further, the component relation table 2a is a drawing equivalent to a circuit diagram (block diagram) by setting the component as a block, the left side of the block as the input side of the component, and the right side of the block as the output side of the component. As shown in FIG.

  If it is determined in step S9 that the signal identification information is not the same (different), the component relationship table creating unit 2 sets new identification information (signal number) in the component relationship table 2a. Then, the process returns to step 11 (step S12).

  Next, in the control interference candidate detection process, first, the computing means 9 has the same identification information (signal number) for all the rows of the component relation table 2a, and the signal type information is the output signal (Out ) Is determined whether or not the presence confirmation of the plurality of rows is completed (step S13).

If it is determined in step S13 that the presence check has been completed, the control interference candidate detection process ends.
If it is determined in step S13 that the presence check has not ended, the interference candidate list creation unit 3 identifies the Nth row of identification information (signal) for which the presence check in the component relation table 2a has not ended. Number) is acquired (step S14).

Then, the interference candidate list creation unit 3 extracts a row having the same identification information (signal number) as the acquired identification information (signal number) from the component relation table 2a (step S15).
The interference candidate list creation unit 3 determines whether or not the number of rows whose signal type information is the output signal (Out) among the rows extracted in step S15 is one (step S16).

If it is determined in step S16 that the number of rows whose signal type information is the output signal (Out) is one, the process returns to step S13.
If it is determined in step S16 that the number of rows whose signal type information is the output signal (Out) is not one (a plurality), the interference candidate list creation unit 3 outputs the signal type information. The component identification information of the line which is the signal (Out) is stored in the detected component list 3b (step S17). In addition, when it passes through step S21 mentioned later, the component of the line which uses the signal identification information common to the signal identification information newly detected among the signal identification information extracted by step S20 mentioned later as an output signal (Out) The identification information is stored in the detection component list 3b.

  Here, the lines extracted by the interference candidate list creation unit 3 in step S15 are the 8th, 12th and 20th lines in the component relation table 2a shown in FIG. Among them, the component identification information (“speed control unit”, “power steering control unit”) of the row (the eighth row and the twelfth row) whose signal type information is the output signal (Out) is detected component list 3b ( (See FIG. 14A).

  Further, the interference candidate list creating means 3 detects the signal identification information of the line whose signal type information is the output signal (Out) among the lines extracted in step 15 or the signal identification information extracted in step S20 described later as the detection signal list 3a. (Step S18).

  Here, the lines extracted by the interference candidate list creation unit 3 in step S15 are the 8th, 12th and 20th lines in the component relation table 2a shown in FIG. Among them, the signal identification information (“output instruction”) of the row (the eighth row and the twelfth row) whose signal type information is the output signal (Out) is stored in the detection signal list 3a (see FIG. 13A). To do.

  Here, the single output stage detection means 4 is based on the detection signal list 3a (here, FIG. 13 (a)), the detection component list 3b (here, FIG. 14 (a)) and the component relation table 2a. It is possible to detect a stage constituted by the signal identification information of the input signal and the output signal and the component identification information of the component.

  Then, the interference candidate list creation unit 3 uses the signal identification information of the row whose signal type information is the output signal (Out) among the rows extracted in step 15 or the signal identification common to the signal identification information extracted in step S20 described later. The component identification information of the row whose information is the output signal (Out) is extracted from the component relationship table 2a (step S19).

  Here, among the lines extracted by the interference candidate list creation means 3 in step 15, the lines whose signal type information is the output signal (Out) are the eighth and twelfth lines in the component relation table 2a shown in FIG. The signal identification information of these lines is “output instruction”. For this reason, the component identification information having the input signal identification information (“output instruction”) as the output signal (Out) is “speed control unit” (8th line) and “power steering control unit” (12th line). ).

  Further, the interference candidate list creation unit 3 sets the input signal identification information (signal type information ““ as the signal type information) associated with the component identification information (here, “speed control unit”, “power steering control unit”) extracted in step S19. Signal identification information “In”) is extracted from the component relationship table 2a (step S20).

  Here, the input signal identification information associated with the component identification information “speed control unit” (line 8) includes “constant speed control On / Off” (line 9), “approach signal” (line 8). 10th line) and “traveling speed” (11th line).

  Further, the input signal identification information associated with the component identification information “power steering control unit” (12th line) includes “approach signal” (13th line), “traveling speed” (14th line), and “Angle” (15th line).

  Then, the interference candidate list creation unit 3 determines whether or not the input signal identification information can be extracted in step S20, and if the input signal identification information can be extracted, the extracted input signal identification information indicates the newly detected input signal. It is determined whether it is identification information (whether it is already detected input signal identification information) (step S21). Note that the extracted input signal identification information is newly detected input signal identification information, and the process of step S22 described later is also performed on the input signal identification information extracted in duplicate.

If it is determined in step S21 that the input signal identification information is newly detected, the process returns to step S17.
Here, the input signal identification information extracted in step S20 is “constant speed control On / Off”, “approach signal”, “travel speed”, “approach signal”, “travel speed”, and “angle”. Since it is the detected input signal identification information, the process returns to step S17. Further, since the “approach signal” and “traveling speed” are detected redundantly, the process of step S22 described later is also performed.

  If it is determined in step S21 that the input signal identification information is not newly detected (that is, input signal identification information that has already been detected), the interference candidate list creation unit 3 performs step Of the component identification information extracted in S19, a flag is set in the component identification information of the detected component list 3b corresponding to the component identification information detected in duplicate (step S22), and the process returns to step S13. Moreover, a flag is set to the signal identification information of the detection signal list 3a corresponding to the input signal identification information detected redundantly among the input signal identification information extracted in step S20.

  If it is determined in step S21 that the input signal identification information has not been extracted, the interference candidate detection unit 6 determines whether the control interference candidate is present based on whether or not the flag is set in the detection component list 3b and the detection signal list 3a. It is determined whether or not it exists (step S23).

If it is determined in step S23 that no control interference candidate exists, the process returns to step S13.
If it is determined in step S23 that there is a control interference candidate, the interference candidate detection means 6 is based on the component relationship table 2a and the target integrated control system displayed on the display as the output device 40. With respect to the block diagram, the block of the component corresponding to the component identification information for which the flag is set in the detection component list 3b is emphasized, and the arrow corresponding to the input signal identification information in the detection signal list 3a is emphasized. The control interference candidate is displayed on the display (step S24). Then, the process returns to step 13.

  Then, the processing in steps S13 to S24 is performed for a plurality of rows in which the identification information (signal number) is the same and the signal type information is the output signal (Out) for all rows in the component relationship table 2a. The process is repeated until the presence check is completed ("Yes" is determined in step S13).

In addition, when a control interference candidate is detected using the integrated control system shown in FIG. 17 as a target integrated control system, the following processing is performed as a continuation of step S21 described above.
Since it is determined in step S21 that the input signal identification information is newly detected, the process returns to step S17.

  The interference candidate list creation means 3 extracts the signal identification information extracted in step S20 (“constant speed control On / Off”, “approach signal”, “travel speed”, “approach signal”, “travel speed”, “angle”). Among these, the component identification of the row (the first row, the fifth row, the third row, the fourth row) that uses the signal identification information common to the newly detected signal identification information as the output signal (Out) Information (“constant speed SW”, “curve detection control unit”, “speed sensor”, “steering angle sensor”) is stored in the detection component list 3b (see FIG. 14B) (step S17a). Of the signal identification information extracted in step S20, the “approach signal” and the “traveling speed” are detected redundantly, and therefore the corresponding component identification information “curve detection control unit” and In step 22a, the “speed sensor” sets a flag in the component identification information of the detection component list 3b.

  Further, the interference candidate list creation means 3 generates the signal identification information (“constant speed control On / Off”, “approach signal”, “travel speed”, “approach signal”, “travel speed”, “angle”, extracted in step S20. ”) Is stored in the detection signal list 3a (see FIG. 13B) (step S18a).

  The interference candidate list creation means 3 then extracts the signal identification information (“constant speed control On / Off”, “approach signal”, “travel speed”, “approach signal”, “travel speed”, “angle”, extracted in step S20. ”) Component identification information (“ constant speed SW ”) of the rows (first row, fifth row, third row, fourth row) whose signal identification information is common to the output signal (Out), “Curve detection control unit”, “speed sensor”, “steering angle sensor”) are extracted from the component relationship table 2a (step S19a).

  In addition, the interference candidate list creation unit 3 inputs corresponding to the component identification information (“constant speed SW”, “curve detection control unit”, “speed sensor”, “steering angle sensor”) extracted in step S19a. Signal identification information (“position” (sixth line), “traveling speed” (seventh line)) is extracted from the component relationship table 2a (step S20a).

  Then, the interference candidate list creation unit 3 determines whether or not the input signal identification information has been extracted in step S20a, and if the input signal identification information can be extracted, the input signal identification newly detected by the extracted input signal identification information. It is determined whether it is information (step S21a).

  Here, the input signal identification information (“position”, “traveling speed”) can be extracted in step S20a, and the extracted input signal identification information (“position”) is the newly detected input signal identification information. To return to step S17.

  The interference candidate list creation means 3 outputs the signal identification information common to the newly detected signal identification information (“position”) among the signal identification information (“position”, “traveling speed”) extracted in step S20a as an output signal. The component identification information (“GPS sensor”) of the row (second row) to be (Out) is stored in the detection component list 3b (see FIG. 14C) (step S17b). Of the signal identification information extracted in step S20a, since “traveling speed” has already been detected, the “speed sensor”, which is the corresponding component identification information, is detected in step 22b. A flag is set in the component identification information 3b.

  Further, the interference candidate list creation unit 3 stores the signal identification information (“position”, “traveling speed”) extracted in step S20a in the detection signal list 3a (see FIG. 13C) (step S18b).

  Then, the interference candidate list creation unit 3 uses the signal identification information common to the signal identification information (“position”, “traveling speed”) extracted in step S20a as the output signal (Out) (second line, second line). The component identification information (“GPS sensor”, “speed sensor”) in the third row) is extracted from the component relationship table 2a (step S19b).

  Further, the interference candidate list creation means 3 uses the input signal identification information (here, not present) associated with the component identification information (“GPS sensor”, “speed sensor”) extracted in step S19b as the component relationship. Extracted from the table 2a (step S20b).

  Then, the interference candidate list creation unit 3 determines whether or not the input signal identification information has been extracted in step S20b, and if the input signal identification information can be extracted, the input signal identification newly detected by the extracted input signal identification information. It is determined whether it is information (step S21b).

Here, it is a case where input signal identification information was not able to be extracted by step S20b, and it progresses to step S23.
Then, the interference candidate detection means 6 determines whether there is a control interference candidate from the presence / absence of flag setting in the detection component list 3b and the detection signal list 3a (step S23b).

  Here, it is a case where it is determined that there is a control interference candidate, and the interference candidate detection means 6 is a block diagram of the target integrated control system displayed by the display which is the output device 40 based on the component relation table 2a. In contrast to (see FIG. 17), the block of the component corresponding to the component identification information (“curve detection control unit”, “speed sensor”) for which the flag is set in the detection component list 3b is emphasized and detected. Emphasize the arrow corresponding to the input signal identification information (“output instruction”, “constant speed control On / Off”, “approach signal”, “travel speed”, “angle”, “position”) in the signal list 3a, Control interference candidates are displayed on the display (step S24b).

  As an example of display on the display, for example, the inside of the block frame corresponding to the component identification information set with the flag in the detection component list 3b shown in FIG. It is conceivable to display a block diagram as shown in FIG. 18 in which the line width of the arrow corresponding to the input signal identification information in the detection signal list 3a shown in FIG.

  Then, the process returns to step 13, and the existence confirmation of the plurality of rows having the same identification information (signal number) and the signal type information being the output signal (Out) is completed for all the rows of the component relationship table 2a. Therefore, the control interference candidate detection process is terminated.

  Here, the plurality of input stage detection means 5 includes the component element identification information ("curve detection control unit") detected in duplicate among the component element identification information in the detection element list 3b (see FIG. 14C), The signal identification information (“approach signal”) of the output signal in the component relation table 2a (see FIG. 12) corresponding to the detected component identification information, and the input signal identification information common to the signal identification information of the output signal Can be detected from the component identification information (“speed control unit”, “power steering control unit”, and “write control unit”) of the component corresponding to. Further, the multiple input stage detection means 5 detects the component element identification information ("speed sensor") detected in duplicate among the element identification information in the detection element list 3b (see FIG. 14C). Corresponds to the signal identification information ("running speed") of the output signal in the component relation table 2a (see FIG. 12) corresponding to the component identification information, and the input signal identification information common to the signal identification information of the output signal. It is possible to detect a stage composed of component identification information (“curve detection control unit”, “speed control unit”, and “power steering control unit”) of the component.

  When the block diagram shown in FIG. 18 is verified, this target integrated control system shows that the output instruction signal contradicts the engine output when the vehicle is at a specific speed and when the vehicle approaches a curve. It can be seen that this may occur.

  In the present embodiment, the signal identification information (signal name) is used for the description. However, the signal identification information (signal name) is further divided into “output up request” and “output down request”. May be. In this case, grouping is performed as the same type of signal, and the above-described processing is performed by replacing the group name with the signal name.

  As described above, in the control interference candidate detection apparatus 10 according to the present embodiment, it is possible to efficiently find a problem location by detecting a control combination that causes control inconsistency from the entire target integrated control system. In addition, there is an effect that it is possible to prevent a detection omission that may occur when the designer visually verifies.
