  The above-described apparatus is intended to assist a software developer or other person familiar with a programming language describing the software when debugging, maintaining, or improving the software.

In modern society, computers are built into many products, and software is executed in them.
When such a product breaks down, for example, if it is a product that cannot be moved from the installation location such as an elevator, a repair person will go to the site and repair it. When a repair person searches for the cause of a failure, it may be necessary to understand the contents of the software incorporated therein. However, repair personnel are not always familiar with the language in which the software is written.

  In conventional elevators, many programs are implemented by a combination of simple logic such as a ladder language. For this reason, even when a failure occurs, it is relatively easy to search for a variable that causes the failure from the variables that are the direct cause of the failure by analyzing the logical expression. It was possible. However, in recent years, the specifications for elevator control have become large-scale and complicated, and programs are often implemented in high-level languages other than ladder languages. For this reason, it has been difficult to search for a variable that is the cause of a failure from variables that are a direct cause of the failure only by a conventional method of analyzing a logical expression.

  When a failure occurs at the elevator installation site, the variable A that originally turns on the hardware is investigated in the situation where the variable A that turns on the hardware is not turned on. Investigate whether A is not turned ON, where variable A is used in the program, and what is the condition that does not turn variable A ON, and eventually cause failure Searching for variables. This search is relatively easy when the program is implemented with a simple logic combination such as a ladder, but when the program is implemented with a high-level language such as C language, the efficiency of the search is poor. There was a problem that it was necessary to do this efficiently.

  In addition, in order for a worker who has previously performed a search for a ladder program to perform a search for a high-level language such as C language having a complicated language specification, the gap in understanding the language is overcome. There was a problem that it was necessary.

  Therefore, it is an issue to help those who are not familiar with the programming language describing the software to understand the contents of the software.

  Furthermore, the repair person only needs to understand the contents of the software to the minimum extent necessary for searching for the cause of the failure, and need not know any more.

  Therefore, it is preferable if the device can be analyzed without deeply understanding the contents of the software incorporated in the device.

  An object of the present invention is, for example, to solve the above-described problems, facilitate analysis of a device in which software is incorporated, and improve work efficiency.

An analysis support apparatus according to the present invention includes:
A control unit with built-in executable software;
A control target controlled by the control unit;
In the analysis support device that supports the analysis of the analysis target device having
A source code information storage unit for storing source code information which is information of a source code of the software;

A control signal display unit for displaying the control signal acquired by the control signal acquisition unit;
And a circuit diagram information display unit for displaying circuit diagram information stored in the circuit diagram information storage unit.

  The present invention has an effect of facilitating the understanding of the operator and increasing the efficiency of analysis of the analysis target device by displaying, for example, information about control signals, information about software, and information about circuit diagrams. .

FIG. 3 shows an internal configuration of an elevator 200 (an example of an analysis target apparatus) that is an analysis target. Moreover, the development process of the software 511 which the control part 210 of the elevator 200 performs is shown notionally.
In this example, an elevator will be described as an example of the analysis target device, but any device can be used as long as the device is controlled by software.
The elevator 200 includes a control unit 210 that executes executable software, a control target unit 220 connected to the control unit 210 by a control signal, a connection unit 230 for connecting the analysis support apparatus 100, and the like.
Information collection units such as a rotation speed sensor 221, a position sensor 222, a load weight sensor 223, a destination button 224, and a call button 225 provided in the control target unit 220 collect information from the outside, and control the control unit 210 according to a control signal. To tell.
The control unit 210 executes the software 511 stored in the magnetic disk device 240 and outputs a control signal.
The control signal is transmitted to operation units such as the drive motor 226, the current floor indicator 227, the arrival indicator lamp 228, and the like, and performs a predetermined operation.

  When viewed from the control unit, these control signals are assigned predetermined addresses, and can be written and read in the same manner as for a ROM (Read Only Memory) or a RAM (Random Access Memory).

The software 511 executed in the control unit is described in machine language obtained by compiling source code written in C language at the development stage. The C compiler device 300 compiles and creates the source code 501 and the magnetic disk device 240 of the elevator 200 stores it.
At this time, the address assigned to each control signal is given to the C compiler device 300 as device information 521 at the time of compilation, and the C compiler device 300 sets a variable describing the control signal based on the address as a predetermined address. Convert to
In addition, the device information 521 includes information necessary for compiling the source code into software that can be executed by the control unit 210, such as an address of the RAM 251 that can be used by the control unit 210.
The source code is not limited to the one written in C language, but may be written in a language such as FORTRAN, COBOL, BASIC (basic), or the like. May be assembled. Alternatively, the control unit 210 may execute the source code written in the script language while interpreting it.

In addition to the compiled software 511, the C compiler 300 shows the correspondence between the source code and the address of the machine language 512, the correspondence between the variable described in the source code and the corresponding address on the RAM. A variable storage correspondence relationship 513 or the like is also output.
The address correspondence relationship 512 is stored in the address correspondence relationship storage unit 152 of the analysis support apparatus 100. Similarly, the storage correspondence relationship storage unit 153 stores the variable storage correspondence 513.

Further, the source code analysis device 400 analyzes the same source code 501. The source code analysis device 400 outputs, for example, the following information as the source code analysis information 531.
Function information including function definition position, return value, argument, global variable used, local variable, macro, calling function, called function, function program diagram information.

Macro information, including macro definition and location information used.
Constant information that contains information about where the constant is used.
Global variable dependency information including global variable dependency in function scope.
Further, as the variable correspondence 532, information indicating the correspondence between the variable describing the control signal and the control signal described by the variable is output.
The source code 501 and the source code analysis information 531 are stored in the source code information storage unit 151 of the analysis support apparatus 100 as source code information. The variable correspondence relationship 532 is stored in the description correspondence storage unit 154.

In addition, the circuit diagram information storage unit 155 stores circuit diagram information 551 that is information on the circuit diagram of the elevator 200.
The circuit diagram information 551 includes, for example, circuit diagram image data, circuit diagram CAD (Computer Aided Design) data, and other information related to the circuit diagram itself, the block configuration of the device, and the name of each signal line. Such information is also included.

Further, the control correspondence relationship storage unit 156 stores a control correspondence relationship 561 that indicates the correspondence relationship between the control signal in the elevator 200 and circuit information indicating the circuit portion corresponding to the control signal.
In the control correspondence 561, for example, information indicating correspondence between circuit information indicating a circuit portion corresponding to the information collecting unit of the elevator 200 and a control signal for transmitting the information collected by the information collecting unit to the control unit 210. There are a collection signal correspondence relationship, an operation signal correspondence relationship indicating correspondence between circuit information indicating a circuit portion corresponding to the operation portion of the elevator 200, and a control signal transmitted from the control portion in order to operate the operation portion.
For example, the rotation speed sensor 221 detects the rotation speed of the drive motor 226 and transmits the information as a control signal to the control unit. Therefore, the control signal indicating the rotation speed detected by the rotation speed sensor 221 corresponds to the circuit information indicating the rotation speed sensor 221 in the circuit information.

Each storage unit of the analysis support apparatus 100 stores such information in the magnetic disk device 920 of the analysis support apparatus 100.
Since these pieces of information are usually output in the form of electronic data, they are stored on a flexible disk and read by the analysis support apparatus 100. Alternatively, it may be stored in a server connected to the Internet or the like and downloaded by the analysis support apparatus 100 as necessary. Furthermore, the analysis support apparatus 100 may be configured to automatically read when the type of the analysis target apparatus is input.

FIG. 4 shows a part related to the display unit in the analysis support apparatus 100.
The analysis support apparatus 100 is roughly divided into three display units.

  The control signal display unit 111 displays a control signal name and content of the control signal in the elevator 200 on a CRT (Cathode-Ray Tube) 901. The content of the control signal is acquired by the control signal acquisition unit 141 communicating with the connection unit 230 of the elevator 200. However, it may be obtained by connecting directly to a signal line for transmitting a control signal via the connecting portion 230 of the elevator 200.

The source code information display unit 112 displays the source code information stored in the source code information storage unit 151 on the CRT. Source code information includes source code 501 and source code analysis information 531.
5 and 6 show examples of source code information displayed by the source code information display unit 112. FIG.

  5 shows the source code information, function definition position, return value, argument, used global variable (global variable), used local variable (local variable), used macro, call The function information including the function being called, the function being called, and the like, and the global variable information including the definition position, type, and used position of the global variable are displayed. In this example, the source code information storage unit 151 stores the source code information in an HTML (Hypertext Markup Language) format, and the source code information display unit 112 converts the display format into a display format for display. However, the source code information storage unit 151 may store the image data to be displayed and display it as it is, or may be stored as a database and converted into a display format for display.

  FIG. 6 is an example in which chart graphic information obtained by graphicizing the control flow of the program is displayed in the source code information. In this example, an HCP chart (Hierarchical and Compact description chart) is used, but a flow chart may be used, and an SPD (Structured Programming Diagram) chart or an NS chart (Nassi chart). -Other structured charts such as (Shneiderman chart) may also be used. Alternatively, a state transition diagram or the like may be used.

  The circuit diagram information display unit 113 displays the circuit diagram information stored in the circuit diagram information storage unit 155 on the CRT 901.

For example, assume that the elevator 200 has failed. A repair person is dispatched to the elevator installation site and begins to search for the fault location.
The person in charge of repair connects the analysis support apparatus 100 to the elevator 200 and checks the control signal.
Here, if a normal control signal is sent from the control unit 210 to the operation unit such as the drive motor 226, but the operation unit that should be operated by that does not operate, the operation unit breaks down. You can see that
Further, if the control signal sent from the information collecting unit such as the rotation speed sensor 221 to the control unit 210 is an abnormal value, it is understood that the information collecting unit is out of order.

  As described above, the CRT 901 of the analysis support apparatus 100 displays the elevator circuit diagram and the source code information of the software executed by the control unit along with the contents of the control signal, so what kind of control signal is output. If it is normal, it is normal and it becomes easy to understand what kind of control signal is abnormal.

  Furthermore, as source code information, not only the source code is displayed as it is, but also the source code is analyzed, and the information obtained as a result is displayed in various forms, so that repair personnel are familiar with the language in which the source code is written. Even if it is not, it becomes easy to understand the processing contents of the software executed by the control unit 210.

  In this way, by displaying information about the control signal of the analysis target device, information about the software executed by the control unit of the analysis target device, and information about the circuit diagram of the analysis target device on the CRT 901, the analysis target device The efficiency of analysis can be increased.

Embodiment 2. FIG.
A second embodiment will be described with reference to FIGS.
The overall configuration of the analysis support apparatus 100 in this embodiment is the same as the configuration described in the first embodiment.

In the example described in the first embodiment, if the information displayed on the CRT 901 of the analysis support apparatus 100 is narrowed down to only necessary information, the efficiency of the repair person in finding the fault location is improved.
For example, if there is a symptom that the drive motor 226 does not move, it is necessary to examine a control signal sent from the control unit 210 to the drive motor 226.
In this embodiment, attention is paid to a specific control signal, and a portion related to the focused control signal is highlighted and displayed.
First, the target control signal determination unit 121 determines a specific control signal as the target control signal.
The control signal display unit 111 highlights and displays the name of the target control signal and the content of the target control signal on the CRT 901.

  Here, “display with emphasis” means to display by changing the color of the part, to display by changing the color of the background of the part, to display the part with a thick line, or to enlarge the part. This means displaying the part in a conspicuous manner by displaying the part in the center of the screen. Also, change the color of the part other than the part to be displayed, change the background color of the part other than the part to display, display the line of the part other than the part to be thin, and display the part other than the part. Display a small part, display a part other than the part at the edge of the screen, omit the details of the part other than the part, display no part other than the part, etc. To include.

A description correspondence storage unit 154 stores a description correspondence that is information about how the control signal is described in the source code.
The target source code information determination unit 122 reads the description correspondence from the description correspondence storage unit 154 and selects the source code information corresponding to the target control signal. When this is sent to the source code information display unit 112 as target source code information, the source code information display unit 112 highlights and displays the target source code information on the CRT 901.

FIG. 7 is an example in which control signals are described in the source code 501.
Here, the control signal is described in the form of a corresponding global variable.
For example, a control signal transmitted from the control unit to control the rotation speed of the drive motor 226 is described by a variable “motor_speed”. When a value is substituted for the variable “motor_speed”, the value is driven as a control signal. It is sent to the motor 226, and the drive motor 226 operates so as to have a given rotation speed.
Therefore, when attention is paid to the control signal for driving the drive motor 226, a portion where the variable “motor_speed” is used in the source code 501 is a portion corresponding to the focus control signal.

In FIG. 8, a variable “global_in” and a variable “global_out” describe control signals in the source code. Here, all the control signals are the target control signals.
Here, the source code information display unit 112 displays chart graphic information in which the flow of software control is graphically included in the source code information. At this time, along with the chart graphic information, the corresponding source code is also displayed, but the lines where the variables “global_in” and “global_out” describing the target control signal appear are displayed as they are. The lines are only comments, and details are omitted. As a result, the line in which the variable describing the target control signal appears becomes conspicuous.

A control correspondence relationship, which is information on which part of the circuit diagram the control signal corresponds to, is stored in the control correspondence relationship storage unit 156.
The target circuit portion determination unit 123 reads the control correspondence from the control correspondence storage unit 156, and selects circuit diagram information corresponding to the target control signal. When this is sent to the circuit diagram information display unit 113 as the circuit portion of interest, the circuit diagram information display portion 113 highlights the circuit diagram information of interest on the CRT 901 and displays it.
For example, when attention is paid to a control signal for driving the drive motor 226, circuit diagram information corresponding to the drive motor 226 becomes a focused circuit portion. When attention is paid to the control signal indicating the rotation speed of the drive motor 226 sent from the rotation speed sensor 221, circuit diagram information corresponding to the rotation speed sensor 221 becomes a circuit portion of interest.

  For example, if there is a symptom that the drive motor 226 does not move, a control signal sent from the control unit 210 to the drive motor 226 is set as a target control signal. Then, the information related to the control signal is highlighted and displayed, so that the person in charge of repair does not have to pay attention to other unnecessary information and can easily find the fault location.

  Thus, by highlighting and displaying information related to the target control signal among the information displayed on the CRT 901, the analysis efficiency of the analysis target device can be increased.

Embodiment 3 FIG.
Embodiment 3 will be described with reference to FIGS.
The overall configuration of the analysis support apparatus 100 in this embodiment is obtained by adding the configuration of FIG. 9 to the configuration described in the first embodiment.
FIG. 9 shows a part of the analysis support apparatus 100 in this embodiment.

  Here, how the target control signal determination unit 121 determines the target control signal will be described.

In the example given in the second embodiment, it is assumed that the person in charge of repair wants to examine a control signal for driving the drive motor 226.
When the person in charge of repair knows the name of the control signal to be noticed, the control signal display unit 111 selects the control signal to be noticed from among the control signals displayed on the CRT 901 and is displayed on the CRT 901 with the mouse 903, for example. Move the mouse pointer and click the control signal. Alternatively, the cursor displayed on the CRT 901 is moved with the cursor key of the keyboard 902 to match the control signal, and the enter key is pressed.
The selection control signal input unit 131 monitors these operations performed by the repair person, uses the control signal selected by the repair person as a selection control signal, and sends the selected control signal to the target control signal determination unit 121.
In this case, the target control signal determination unit 121 determines the selection control signal as it is as the target control signal.

  Accordingly, the target control signal can be easily determined by selecting the control signal that the repair person wants to pay attention to. Since information related to the target control signal is highlighted and displayed, the person in charge of repair does not have to pay attention to other unnecessary information, and can easily find the fault location.

Although the person in charge of repair does not know the name of the control signal for driving the drive motor 226, there may be a case where the portion corresponding to the drive motor 226 is known from the circuit diagram. In that case, the person in charge of the repair performs an operation such as selecting a portion corresponding to the drive motor 226 from the circuit diagram information displayed on the CRT 901 by the circuit diagram information display unit 113 and clicking with the mouse 903.
The selection circuit part input unit 133 monitors these operations by the repair person, makes the circuit part selected by the repair person a selection circuit part, and sends it to the target control signal determination part 121.
A control correspondence relationship, which is information on which part of the circuit diagram the control signal corresponds to, is stored in the control correspondence relationship storage unit 156.
The target control signal determination unit 121 reads the control correspondence from the control correspondence storage unit 156, selects a control signal corresponding to the selection circuit portion, and determines this as a target control signal.

  This makes it possible to easily determine the control signal of interest by selecting the part corresponding to the location where the symptom of the failure appears from the circuit diagram information, even if the repair person does not know the control signal of interest. it can. Since information related to the target control signal is highlighted and displayed, the person in charge of repair does not have to pay attention to other unnecessary information, and can easily find the fault location.

While the person in charge of repair looks at the source code information displayed on the CRT 901 by the source code information display unit 112, a suspicious part may be found. In that case, the person in charge of repair performs an operation such as selecting a suspicious part from the source code information displayed on the CRT 901 by the source code information display unit 112 and clicking with the mouse 903.
The selected source code information input unit 132 monitors these operations by the repair person in charge, and uses the source code information selected by the repair person as selected source code information and sends it to the target control signal determination unit 121.

A description correspondence storage unit 154 stores a description correspondence that is information about how the control signal is described in the source code.
The target control signal determination unit 121 reads the description correspondence from the description correspondence storage unit 154, selects a control signal corresponding to the selected source code information, and determines this as a target control signal.

For example, when the source code information display unit 112 displays the source code information of FIG. 5 on the CRT 901, it is assumed that the repair person clicks on the variable name displayed.
The target control signal discriminating unit 121 determines the correspondence between the variable describing the control signal in the source code 501 and the control signal described by the variable among the description corresponding relationship stored in the description corresponding relationship storage unit 154. The variable correspondence shown is read out, the control signal described by the selected variable is selected, and it is determined as the target control signal.

Further, it is assumed that the repair person clicks a part of the chart figure while the source code information display unit 112 displays the source code information of FIG. 6 on the CRT 901.
The target control signal discriminating unit 121 reads the information about the position where the variable is used in the source code 501 among the description correspondence stored in the description correspondence storage unit 154 and uses it in the selected part. Determine which variables are being used.
Next, the variable correspondence among the description correspondence stored in the description correspondence storage unit 154 is read out, the control signal described by the variable used in the selected portion is selected, and the control signal is selected as the target control signal. It is determined as

  Thus, even when the repair person finds a suspicious part from the source code information, the target control signal can be easily determined by selecting the part. Since information related to the target control signal is highlighted and displayed, the person in charge of repair does not have to pay attention to other unnecessary information, and can easily find the fault location.

When it is known in advance what value the control signal shows when normal, the abnormal control signal determination unit 124 stores the range of the normal control signal and acquired by the control signal acquisition unit 141 When the value of the control signal deviates from the range, the abnormal control signal determination unit 124 determines the control signal as an abnormal control signal.
Alternatively, if the repair person in charge inputs a normal control signal range and deviates from the range, the abnormal control signal determination unit 124 may determine the control signal as an abnormal control signal.
The target control signal determination unit 121 determines the abnormality control signal determined by the abnormality control signal determination unit 124 as it is as the target control signal.

Thereby, the discovery of an abnormal control signal can be automated, and the target control signal can be easily determined. Since information related to the target control signal is highlighted and displayed, the person in charge of repair does not have to pay attention to other unnecessary information, and can easily find the fault location.
As described above, since the target control signal can be easily determined, the analysis efficiency of the analysis target device can be increased.

Embodiment 4 FIG.
A fourth embodiment will be described with reference to FIGS.
The overall configuration of the analysis support apparatus 100 in this embodiment is the same as the configuration described in the third embodiment.

The control unit 210 of the elevator 200 performs complicated calculation based on the input control signal by executing the software 511. Based on the result, a control signal is output.
Therefore, the relationship between the control signals is very complicated.

When a person in charge of repair searches for a faulty part, the search is usually started from a part where a symptom of the fault appears. For example, if the drive motor 226 does not move, a control signal for driving the drive motor 226 is examined.
Here, if the drive motor 226 does not move even though the control signal for driving the drive motor 226 is normal, it is understood that the drive motor 226 has failed.
However, if the control signal for driving the drive motor 226 is an abnormal value in the first place, it is natural that the drive motor 226 does not move, and other parts have failed.
Therefore, the person in charge of repair searches for the cause that the control signal for driving the drive motor 226 shows an abnormal value.

  However, this search is not easy. It is necessary to understand what kind of processing the software 511 executed by the control unit 210 of the elevator 200 performs, and the repair person is familiar with the language in which the source code 501 of the software 511 is described. Because there is no limit.

  Since the person in charge of the repair is trying to search for the cause of the control signal indicating an abnormal value, the control signal affecting the control signal indicating the abnormal value is detected by the execution of the software 511 in the control unit 210 of the elevator 200. You want to know which one.

  Therefore, in this embodiment, based on the target control signal determined by the target control signal determination unit 121, the dependency control signal determination unit 125 determines a control signal having a dependency relationship with the target control signal as a dependency control signal, The control signal determination unit 121 determines the dependency control signal as the target control signal.

Here, the dependency relationship is a relationship between two control signals having a relationship in which a control signal input to the control unit 210 executing the software 511 affects the control signal output from the control unit 210. The relationship between.
10 to 13 are examples of the source code 501 of the software 511 executed by the control unit 210.

In FIG. 10, a variable “g_in1” and a variable “g_out1” both describe control signals in the source code 501.
In the function “func_X”, the value of the variable “g_in1” is assigned to the variable “g_out1”. Therefore, when the function “func_X” is executed, if the value of the variable “g_in1” changes, the value of the variable “g_out1” also changes. Therefore, if the value of the control signal described by the variable “g_in1” changes, the value of the control signal described by the variable “g_out1” also changes. That is, there is a dependency relationship between the two control signals by substitution.

In FIG. 11, a variable “g_in2” and a variable “g_out2” both describe control signals in the source code 501. However, the variable “l_cyukan1” is provided for temporarily storing a value and is not related to the control signal.
In the function “func_X”, the variable “g_in2” and the variable “g_out2” are not described on the right side and the left side of one assignment expression, and thus seem to have no relation. However, in practice, the value of the variable “g_in2” is substituted into the variable “l_chukan1”, and the value of the variable “l_chukan1” is substituted into the variable “g_out2”. Therefore, if the value of the variable “g_in2” is changed, the value of the variable “l_cyukan1” is changed, and as a result, the value of the variable “g_out2” is also changed. That is, there is still a dependency relationship between the control signal described by the variable “g_in2” and the control signal described by the variable “g_out2”.

In FIG. 12, a variable “g_in3” and a variable “g_out3” both describe a control signal in the source code 501.
In the function “func_X”, the execution path of the software changes depending on whether the value of the variable “g_in3” is equal to zero. The value assigned to the variable “g_out3” changes as the execution path of the software changes. Therefore, if the value of the variable “g_in3” changes, the value of the variable “g_out3” may also change. That is, there is a dependency relationship due to conditional branching between the control signal described by the variable “g_in3” and the control signal described by the variable “g_out3”.

In FIG. 13, a variable “g_in4” and a variable “g_out4” both describe control signals in the source code 501. However, the variable “l_cyukan2” is provided for temporarily storing a value and is irrelevant to the control signal.
In the function “func_X”, the value of the variable “g_in3” is substituted into the variable “l_cyukan2”. Next, the execution path of the software changes depending on whether the value of the variable “l_cyukan2” is equal to zero. The value assigned to the variable “g_out4” changes as the execution path of the software changes. Therefore, if the value of the variable “g_in4” changes, the value of the variable “g_out4” may also change. In other words, there is a dependency relationship between the control signal described by the variable “g_in4” and the control signal described by the variable “g_out4” due to conditional branching.

Based on such dependency relationships, it is possible to narrow down the control signals that cause a certain control signal to show an abnormal value. That is, there should be a control signal that is caused by one of the control signals that have a dependency relationship with the control signal that indicates an abnormal value. A control signal that does not depend on the control signal is irrelevant.
Therefore, the person in charge of repair need only search for a control signal having a dependency relationship with a control signal indicating an abnormal value.

Therefore, in this embodiment, a control signal having a dependency relationship with the target control signal is also used as the target control signal, so that information related to the control signal is emphasized and displayed. The repair staff will not be distracted by other unnecessary information, and will be able to easily find the fault location.
In addition, when there are a plurality of target control signals, a control signal having a dependency relationship with two or more target control signals may be used as a control signal to be particularly focused, and information related thereto may be further emphasized and displayed. . When two or more symptoms occur at the same time, the failure that is the cause is often one. Therefore, this makes it possible to further narrow down the control signals to be searched.

  Alternatively, a control signal having a dependency relationship with the dependency control signal may be displayed as a target control signal with emphasis on information related thereto. Then, if there is a cause in a certain control signal, it is possible to focus on control signals that are likely to have other effects. As a result, if the other control signals are not affected, the repair person can infer that the control signals may be the cause.

  As a result, even if the person in charge of repair is not familiar with the language in which the source code 501 is described, it becomes easy to narrow down the control signal to be searched, and the fault location can be easily found.

  As described above, since the target control signal can be easily narrowed down, the analysis efficiency of the analysis target device can be increased.

Embodiment 5. FIG.
A fifth embodiment will be described with reference to FIGS. 1 to 3 and FIG.
1 to 3 show the configuration of the analysis support apparatus 100 according to this embodiment. The description of the drawings has been described in Embodiment 1, and is therefore omitted here.
The analysis support apparatus 100 in this embodiment further has a configuration shown in FIG.

The control unit 210 of the elevator 200 usually does not execute all parts of the software 511. In the control flow of the software 511, there are some branch points and merging points, which are executed only when a certain condition is satisfied.
Therefore, when the condition is not satisfied, there is a portion that is not executed in the software 511.

  That is, it is not necessary to display source code information corresponding to a portion that is not actually executed in the source code information displayed on the CRT 901 by the source code information display unit 112. On the contrary, if such source code information is displayed, the person in charge of the repair will be distracted by that part, which may cause the efficiency of finding the faulty part to deteriorate.

  Therefore, in this embodiment, the execution source code information determination unit 161 determines the execution path of the software that is actually executed by the control unit 210 of the elevator 200, and the source stored in the source code information storage unit 151 Among the code information, source code information related to the execution path is determined as execution source code information. The source code information display unit 112 highlights and displays the execution source code information among the source code information stored in the source code information storage unit 151.

  As a result, the person in charge of repair does not have to pay attention to other unnecessary information and can easily find the faulty part.

  Thus, by highlighting and displaying information related to the execution path that is actually executed among the information displayed on the CRT 901, the efficiency of analysis of the analysis target device can be increased.

Embodiment 6 FIG.
A sixth embodiment will be described with reference to FIGS. 1 to 3 and FIGS. 14 to 16.
The overall configuration of the analysis support apparatus 100 in this embodiment is the same as the configuration described in the fifth embodiment.

  Here, how the execution source code information determination unit 161 determines execution source code information will be described.

FIGS. 15 and 16 show an example of the source code 501 of the software 511 executed by the control unit 210 and chart graphic information displayed on the CRT 901 by the source code information display unit 112 correspondingly. In this example, a flowchart is used as the chart graphic information.
In FIG. 15, the source code of this example can be divided into four parts at the branch position and the merge position according to the flow of control. That is, when the function “func_X” is executed, the “/ * processing A * /” portion is always executed, but the “/ * processing B * /” portion is executed when the branch condition “g_in1> 0” is true. Only executed. On the contrary, the part of “/ * processing C * /” is executed only when the branch condition “g_in1> 0” is false. Thereafter, the flow of control is merged, and the portion of “/ * Processing D * /” is always executed.
Therefore, whether to execute “/ * processing B * /” or “/ * processing C * /” can be determined by checking whether the branch condition “g_in1> 0” is true.

In FIG. 15, a variable “g_in1” describes a control signal in the source code 501.
Therefore, if the value of the control signal described by the variable “g_in1” is known, it can be determined whether the branch condition “g_in1> 0” is true, and “/ * processing B * /” and “/ * processing C * /”. It is possible to determine which one is executed.

The control signal acquisition unit 141 acquires the contents of the control signal.
The execution source code information determination unit 161 reads the variable correspondence relationship 532 stored in the description correspondence relationship storage unit 154, and obtains the value of the variable “g_in1” from the value of the control signal described by the variable “g_in1”. .
The execution source code information determination unit 161 further determines whether the branch condition “g_in1> 0” is true from the value of the variable “g_in1”. In the following description, it is assumed that the branch condition “g_in1> 0” is true.
Since the branch condition “g_in1> 0” is true, the execution source code information determination unit 161 has a source corresponding to “/ * processing A * /”, “/ * processing B * /”, and “/ * processing D * /”. Code information is determined as execution source code information.
The source code information display unit 112 highlights and displays the execution source code information. In FIG. 15, the portion corresponding to “/ * processing A * /”, “/ * processing B * /”, “/ * processing D * /” is enlarged and the line is made thick so that the highlighted portion is displayed. It stands out.

  In this way, by specifying the execution path of the software 511 that is actually executed by the control unit 210 of the elevator 200 based on the control signal acquired by the control signal acquisition unit 141, internal information (for example, for example, the control unit 210) Since it is not necessary to acquire an execution address or the like, the number of devices necessary for connecting the elevator 200 and the analysis support device 100 can be reduced.

  In FIG. 16, the source code of this example can be divided into five parts at the branch position and the merge position according to the flow of control. That is, the part “/ * process A * /” that is always executed and the part “/ * process B * /” “/ * process C * /” “/ *” that are selectively executed according to the value of the variable “g_in2”. “Process D * /” and a part “/ * Process E * /” that is always executed after that.

  In FIG. 16, a variable “g_in2” describes a control signal in the source code 501, but a variable “local” is provided for temporarily storing a value. It has nothing to do with it.

In order for the control unit 210 to know which process is being executed among “/ * process B * /”, “/ * process C * /”, and “/ * process D * /”, it is necessary to check the branch condition. There is.
When the branch condition “g_in2 = 0” is true, “/ * processing B * /” is executed.
If the branch condition “g_in2 = 0” is false but the branch condition “g_in2 = local” is true, “/ * processing C * /” is executed.
If both of the above branch conditions are false, “/ * process D * /” is executed.

  In order to know whether or not the branch condition “g_in2 = 0” is true, it is necessary to know the value of the variable “g_in2”. Since the variable “g_in2” describes the control signal in the source code 501, if the value of the control signal described by the variable “g_in2” is known, the value of the variable “g_in2” is known.

The control signal acquisition unit 141 acquires the contents of the control signal.
The execution source code information determination unit 161 reads the variable correspondence relationship 532 stored in the description correspondence storage unit 154 and obtains the value of the variable “g_in2” from the value of the control signal described by the variable “g_in2”. .
The execution source code information discriminating unit 161 further determines whether the branch condition “g_in2 = 0” is true from the value of the variable “g_in2”, and corresponds to “/ * processing B * /” if true. The source code information is determined as execution source code information.

When the branch condition “g_in2 = 0” is false, it is necessary to know whether the branch condition “g_in2 = local” is true. For this purpose, not only the value of the variable “g_in2” but also the value of the variable “local” must be known.
Since the variable “local” does not describe the control signal in the source code 501, the value of the variable “local” cannot be known from the value of the control signal acquired by the control signal acquisition unit 141.

In order to know the value of the variable “local”, the processing of the software 511 executed by the control unit 210 of the elevator 200 may be simulated inside the analysis support apparatus 100.
That is, since the control signal acquisition unit 141 acquires the value of the control signal input to the control unit 210 of the elevator 200, the value of the variable describing the control signal can be obtained based on the value.
Next, when the value of another variable is calculated based on the value, the same calculation as the calculation is performed to obtain the value of the other variable.
Further, when the flow of control branches depending on the values of these variables, it is checked whether the branch condition is satisfied based on the calculated values of the variables, and the process to be executed next is obtained.
Thus, the value of the variable “local” can be known by imitating the processing of the software 511 executed by the control unit 210 of the elevator 200 inside the analysis support apparatus 100.

  In this way, by specifying the execution path of the software 511 that is actually executed by the control unit 210 of the elevator 200 based only on the control signal acquired by the control signal acquisition unit 141, internal information (for example, the control unit 210) , The execution address, etc.) need not be acquired, so that the number of devices necessary for connecting the elevator 200 and the analysis support device 100 can be reduced.

But there is another way. The RAM 251 of the elevator 200 stores the value of the variable “local”. If the content is acquired, the value of the variable “local” can be known.
The storage content of the RAM 251 of the elevator 200 is acquired by the storage content acquisition unit 142 communicating with the connection unit 230 of the elevator 200. However, it may be directly connected to the RAM 251 via the connection unit 230 of the elevator 200 and acquired by, for example, DMA (Direct Memory Access).
The execution source code information discriminating unit 161 discriminates where the value of the variable “local” is in the stored contents of the RAM 251 by the variable storage correspondence 513 stored in the storage correspondence storage unit 153, and sets the variable “ The value of “local” is obtained.

  In the method of simulating the processing of the software 511, there is a possibility that a value different from the value of the control signal acquired by the control unit 210 of the elevator 200 may be acquired depending on the timing of acquiring the control signal. As a result, the value of the variable “local” by simulation is different from the actual value, and the source code information that does not correspond to the actual execution path may be erroneously determined as the execution source code information.

  However, if the value of the variable “local” is obtained by acquiring the stored contents of the RAM 251 of the elevator 200, the value does not become different from the actual value, so that the execution source code information is not erroneously determined. .

  In this way, by providing the storage content acquisition unit 142 that acquires the storage content stored in the RAM 251 of the elevator 200, the execution path of the software 511 that is actually executed by the control unit 210 of the elevator 200 can be specified. There is no need to simulate the process 511, and there is no worry of erroneously determining execution source code information.

As described above, when it is found that the branch condition “g_in2 = local” is true, the execution source code information determination unit 161 always executes “/ * processing A * /” “/ * processing E * /” and Source code information corresponding to “/ * process C ** /” that is selectively executed is determined as execution source code information.
The source code information display unit 112 highlights and displays the execution source code information. In FIG. 16, not only the portions corresponding to “/ * processing A * /”, “/ * processing C * /”, “/ * processing E * /” are enlarged and the lines are thickened, but other than that The highlighted portion is made conspicuous by not displaying the portion corresponding to “/ * processing B * /” and “/ * processing D * /”.

  Note that it is preferable that the variable values calculated or obtained as described above are displayed on the CRT 901 because it is easier to understand the operation of the software.

Embodiment 7 FIG.
A seventh embodiment will be described with reference to FIGS. 1 to 3 and FIG.
1 to 3 show the configuration of the analysis support apparatus 100 according to this embodiment. Since the description of the drawings has been described in Embodiment 1, it is omitted here.
The analysis support apparatus 100 in this embodiment further has a configuration shown in FIG.

There is another method for determining the execution source code information corresponding to the execution path of the software 511 that is actually executed by the control unit 210 of the elevator 200.
If the execution address that is the address on the memory of the software 511 that is actually executed, such as the value of the PC (Program Counter) of the control unit 210 of the elevator 200, is acquired, the execution path can be specified, and it corresponds Execution source code information to be determined.

  The execution address acquisition unit 143 acquires the execution address via the connection unit 230 of the elevator 200. Specifically, the address that is output at the timing when the control unit 210 reads the instruction word by monitoring the address bus is the execution address. Alternatively, if a hardware interrupt is periodically given to the control unit 210 and the saved return address is acquired, the execution address at that time can be known. The part that performs these operations is provided in the elevator 200, and the execution address acquisition unit 143 communicates with the connection unit 230 to acquire the execution address. However, the execution address acquisition unit 143 may be directly connected to the control unit 210 via the connection unit 230, and the execution address acquisition unit 143 may perform these operations to acquire the execution address.

  The execution source code information determination unit 161 determines the source code information corresponding to the execution address as execution source code information based on the address correspondence relationship 512 stored in the address correspondence relationship storage unit 152.

  Thus, by providing the execution address acquisition unit 143 that acquires the execution address of the control unit 210 of the elevator 200, the execution path of the software 511 that is actually executed by the control unit 210 of the elevator 200 can be specified. There is no need to simulate the process 511, and there is no worry of erroneously determining execution source code information.

  In the present embodiment, unlike the first to seventh embodiments, the elevator failure analysis device includes a source code analysis device 400.

  In this embodiment, the elevator failure analysis apparatus 1 sets a program described in C language, which is a high-level language as shown in FIG. 5, as a failure analysis target program.

The software failure analysis unit 671 analyzes the source code of the software of the analysis target device stored in the analysis target software storage unit 651, and generates elevator failure analysis information including the following information.
Function information:
Function information and global variable information including function definition position, return value, argument, used global variable, local variable, macro, calling function, called function, function program diagram information:

  As described above, the analysis support apparatus includes the source code analysis apparatus, so that it is not necessary to analyze the source code in advance.

Embodiment 9 FIG.
The configuration of the analysis support apparatus 100 in this embodiment is the same as that described in the eighth embodiment.
In this embodiment, when generating a program diagram, only information necessary for the operator is generated.

The conventional program diagram information creation device can extract information of both source and comment, source only, and comment only.

  However, extracting information from all sources as program diagram information may give unnecessary information to the operator, so program diagram information is not generated for all source information. Focusing on the above, it may be desirable to extract only the information necessary for the worker as the source of the program diagram and generate the program diagram.

  For example, if the most effective information for the failure analysis of the elevator is information on reading and writing to the global variable, the worker analyzes the program to extract the portion of reading and writing to the global variable. With the software of FIG. 6, with the conventional program diagram generation tool, when trying to extract source and comment information, even the source unrelated to reading and writing of global variables is displayed as shown in FIG. When this apparatus is used, since a program diagram is generated after analyzing a grammatical element of a program, it is possible to generate a program diagram as shown in FIG. 8 including only sources related to reading and writing of global variables. Narrowing down the information necessary for the worker can be given not only by grammar elements but also by other rules such as variable and function naming rules.

  In this way, at the programming stage, it is described in advance so that information necessary for the operator and information that is not necessary can be distinguished in the source code, and based on the description, the portion to be highlighted is selected. This makes it possible for workers to find information that should be noticed more quickly.

Embodiment 10 FIG.
The configuration of the analysis support apparatus 100 in this embodiment is the same as that described in the eighth embodiment.
This embodiment further supports narrowing down the variables on which the variable to be analyzed depends in the function scope.

The variable dependency analyzing unit 672 can extract the dependency relationship of the global variable in the function scope. By extracting the dependency relationship of global variables in the function scope, it is useful for investigating the cause of the failure focusing on the signal where the elevator has failed. There are the following types of dependencies.
・ Dependency related to substitution ・ Dependency related to control In addition, the dependency described above may be established via an internal variable.

  The dependency relationship regarding substitution is the relationship between the global variables g_out1 and g_in1 shown in FIG. 10, and g_out1 depends on g_in1. This is generally the relationship that the global variable on the left side of the assignment expression depends on the global variable contained on the right side of the assignment expression.

  FIG. 11 shows an example in which the dependency relation regarding substitution is established via an internal variable. This is the relationship between the global variables g_out2 and g_in2 shown in the figure, and g_out2 depends on g_in2. In this example, the dependency relation regarding the substitution is established through the internal variable l_cyukan1. In general, a dependency related to assignment is established through an internal variable. A global variable that is dependent on an assignment dependency is assigned to an internal variable A, and the left side of the assignment expression is a global that depends on an assignment dependency. This is a case where the internal variable A is included on the right side of the assignment expression.

  The dependency relation regarding control is the relation between the global variables g_out3 and g_in3 shown in FIG. 12, and g_out3 depends on g_in3. In general, this is a relationship in which a global variable whose value is changed depending on the evaluation result of the conditional expression of the control statement depends on the global variable included in the conditional expression of the control statement.

  An example in which the dependency relation regarding control is established through an internal variable is shown in the figure. The relationship between the global variables g_out4 and g_in4 shown in FIG. 13 is dependent on g_in4. In this example, the dependency relation regarding the control is established through an internal variable l_cyukan2. In general, a control dependency is established through an internal variable. A global variable that is dependent on the control dependency is assigned to the internal variable A, and the global variable that is dependent on the assignment dependency is the condition of the control statement. This is a global variable whose value is changed according to the evaluation result of the expression, and the internal variable A is included in the control expression of the control statement.

  In this way, by displaying the dependency relationship between variables, it is possible to easily narrow down information that should be noted by the operator.

Embodiment 11 FIG.
The configuration of the analysis support apparatus 100 in this embodiment is the same as that described in the eighth embodiment.
This embodiment further communicates with an operating elevator to obtain the value of a variable to be analyzed.

  The elevator communication unit 641 is a communication interface between the elevator failure analysis apparatus 100 and the elevator 200, and refers to the state of a signal of an arbitrary elevator by designating the actual address of the software, the scope of the variable in the program, and the variable name. Or change. By passing through the elevator failure analysis apparatus 100, information on the value of any global variable in the elevator failure analysis information is acquired from the elevator, and the variable value display unit 613 displays the acquired value.

  In this way, in addition to acquiring information from the analysis target device, if the configuration is such that the signal state of the analysis target device can be directly changed, how the change in the signal state actually affects the operation of the analysis target device. Since it is possible to directly confirm whether or not to do so, the analysis efficiency of the analysis target device is increased.

Embodiment 12 FIG.
The configuration of the analysis support apparatus 100 in this embodiment is the same as that described in the eighth embodiment.
This embodiment further displays the program path being executed in the program diagram with reference to the value of the variable acquired by communicating with the elevator in operation.

  The execution path display unit periodically obtains information on global variables that affect the execution path of the elevator program through the elevator communication unit, thereby monitoring the execution path of the program and displaying the result. FIG. 19 shows the source code of the software to be analyzed. In the source code of this software, global variables g_in1 and g_in2 are variables that determine the execution path of the function func_X () including a branch. The execution path display unit 612 periodically obtains the values of g_in1 and g_in2 via the elevator communication unit 641.

  If g_in1 is greater than 0, / * execute the path A1 * / to change the color of the part so that the operator can recognize that it is being executed. If g_in1 is 0 or less, / * The route A2 is executed. * The color of the portion of * / is changed so that the operator can recognize that it is being executed.

  When g_in2 is 0, / * execute the path B1 **, for example, by changing the color of the part so that the operator can recognize that it is being executed. When g_in2 is 1, / * the path B2 ** Change the color of the part * / so that the operator can recognize that it is being executed.
