Description

  The present invention relates to an automatic operation system that controls the speed and torque of a device to be controlled, such as a dynamometer and a pump, according to a specified operation pattern, and more particularly to a method for creating / changing an operation pattern.

As an automatic driving system of this type, an application example to an engine test dynamometer is shown in FIG. 4 (see, for example, Patent Document 1). A dynamometer 3 having a motor configuration is directly connected to the output shaft of the engine 1 via a connecting shaft 2, and the output torque of the engine 1 is absorbed by the dynamometer 3. The torque control is performed by current control of dynamometer 3 by the torque controller 5 from the comparison between the detected torque by the torque command T _S and a torque meter 4.

Speed controller 6 obtains a speed command N opening control signal _S and the comparison of the detected speed of the speed detector 7 of the engine 1 throttle valve 1A theta *. The throttle controller 8 controls the opening of the throttle valve 1A via the throttle actuator 9 using the opening control signal θ * as an opening command.

Automatic operation command device 10 is a computer configuration, test engine (running test, such as the output test) generates a speed command N _S and the torque command T _S which changes every moment generated in accordance with the purpose.

  These commands are created as operation command data according to an operation pattern in which values for each period of acceleration, constant speed, and deceleration are set in units of steps, as shown in an example in a running test in FIG. Although some driving patterns are predetermined, unique patterns are often created according to the purpose of the test.

  The driving pattern, as shown in the table form in the figure, defines the value and time for each step as two-dimensional data, and according to this data, the automatic driving command device 10 has a constant inclination during acceleration and deceleration. A speed or torque command that changes with the speed is generated, and a constant speed or torque command is generated at a constant speed.

As shown in FIG. 6, an actual operation pattern is created in a data format format (CSV format) that enumerates data with commas as delimiters.
Japanese Patent Laid-Open No. 11-24703

  ・ In the case of CSV format, the operation pattern is only a list of data. For this reason, it is difficult to understand at a glance what each data represents, and it is difficult for a person to check an error of an operation pattern.

  For example, in “SWEEPEG, ATR, 716.0, 2” in FIG. 6, “SWEEPEG” represents the name of the pattern, “ATR” represents the control type, “716.0” represents the torque command value, “2” represents time (seconds), but simply writing “2” makes it difficult to understand what this means unless it is a person in charge or a designer.

  -In the CSV format, the order of data is an important factor. When the structure of the driving pattern is changed, such as increasing or decreasing part of the data or changing the unit, it is difficult to identify the corresponding part of the driving pattern. Yes, this change is not easy.

  For example, as shown in the example of change in FIG. 7, “SWEEPEG, ATR, 716.0, 2” before the change and “2” at the end represent time, but this portion is expressed as “step size” and “ If it is changed to “time”, the automatic operation command device 10 or the like recognizes the time “2” as a step size.

  If the unit of “2” represents “seconds” before the change, but changes the unit to “milliseconds”, “2” needs to be changed to “2000”.

  ・ When there are many controlled objects and there are many types of operation modes, a special tool is required to eliminate the above inconveniences and create / change (correct, delete, add, etc.) accurate operation patterns. This tool itself requires a complicated software configuration.

  An object of the present invention is to provide an operation pattern creation / change method and an automatic operation system that facilitate the creation / change of an operation pattern and facilitates the recognition and change of the operation pattern by a person.

  In order to solve the above-described problems, the present invention acquires an XML schema document that defines an operation pattern structure, and an XML document of an operation pattern that is described according to the operation pattern structure, and checks the validity of the operation pattern based on these documents. In addition, the operation pattern interpretation program is automatically created from the operation pattern structure, and the operation pattern data in the XML document can be automatically expanded to the operation pattern data that can be used in the automatic operation system by the operation pattern interpretation program. Features the following methods and systems.

In addition, the operation pattern interpretation program is automatically created from the operation pattern structure, and the operation pattern data can be automatically expanded from the operation pattern of the XML document to the operation pattern data usable in the automatic operation system by the operation pattern interpretation program. It is easy to create and change, and the person can easily recognize and change the driving pattern. Specifically, the following effects are obtained.

  ・ Because driving patterns can be described in XML documents, restrictions on data loss and arrangement order are relaxed and connectivity is improved.

  -Since there is information representing the contents of data in the tag, it becomes easier to understand what the data represents at a glance (improvement of readability). In addition, a change in tag name or a new tag is sufficient for changing the structure of the operation pattern.

  -Because the operation pattern can be described in an XML document, a dedicated tool for XML can be used without creating a dedicated tool when creating or changing the operation pattern.

  An operation pattern interpretation program can be automatically generated from an XML schema document that defines the structure of the operation pattern, and it is not necessary to redesign the operation test program when the structure of the operation pattern is changed.

  -By checking the validity of the structure of the created operation pattern before automatic operation, unexpected patterns will not appear during test execution.

  -In the CSV format, only a two-dimensional data structure can be expressed, but in the XML schema, a multi-dimensional data structure with a nested structure can be expressed, so that a design similar to a database can be performed.

(1) Creation of Driving Pattern FIG. 1 shows a procedure for creating driving pattern data showing an embodiment of the present invention, which is realized by a software configuration for creating and changing a driving pattern in an XML document. Will be described in detail.

  (S1) An XML schema document that defines a structure (relation between elements, attributes, types, groups, etc.) that can be taken by the XML document of the operation pattern is acquired as electronic data by an input device or the like. This XML schema document is created in advance, and an example thereof is shown in FIG. 2. In the structure definition sentence A, “the operation pattern is composed of a plurality of steps” is described, and in the structure definition sentence B, “step Is composed of a plurality of step contents, and further has a number and a time ”, and the structure definition sentence C describes“ the step contents have a name, a control type, a command value, and a time ”.

  (S2) An XML document defining an operation pattern to be actually tested is acquired as digitized data by an input device or the like. The operation pattern of the XML document is created in advance by an XML tool (for example, a text editor), and an example thereof is shown in FIG. 3. The pattern sentence P1 includes “the operation pattern is composed of two steps, 1 The first step is number 1, time 4, and is composed of two step contents. The first step contents include name SWEEPEG, control type ATR, command value-716.0, time 2 ". The pattern sentence P2 is similarly described.

  (S3) The validity of the XML document acquired in (S2) is checked using the operation pattern definition structure that becomes the XML schema document acquired in (S1) above. With this check, the correctness of the XML document is automatically extracted by collation between the XML schema document and the XML document.

  (S4) When an error occurs in the check of (S3) above, error information is displayed collectively or sequentially. This display can be displayed using an XML tool (for example, a converter).

  (S5) In response to the display of the error information in (S4) above, an error correction input by a person is made possible by using an XML tool (for example, a text editor), and the process returns to (S3).

  (S6) An operation pattern interpretation program is automatically created using an XML tool (for example, a converter) according to the operation pattern definition structure that becomes the XML schema document acquired in (S1) above.

  (S7) Using the interpretation program created in (S6) above, the XML document corrected in error in (S3) to (S5) is read and automatically developed into operation pattern data in a format that can be used in the automatic operation system.

  (S8) The operation pattern data developed in (S7) above is output, that is, transmitted or transferred to the automatic operation command device 10 to enable automatic operation of the system.

  As described above, the operation pattern can be created by automatically checking the validity of the operation pattern and correcting it by creating the structure that can be taken by the XML document defined in the XML schema document and the operation pattern created by the XML document. In addition, by automatically creating an operation pattern interpretation program from an XML schema document, the operation pattern of the XML document can be automatically expanded into operation pattern data that can be used in the automatic operation system. is there.

  -Since the operation pattern can be described in an XML document, restrictions on data loss and arrangement order are relaxed, and connectivity is improved.

  -The operation pattern structure and operation pattern are XML schema documents and XML documents, and information indicating the contents of the data exists in the tags, making it easy to understand what the data represents at a glance (improvement of readability) ).

  -Since the operation pattern definition structure and the operation pattern can be described in an XML document, a general-purpose text editor can be used without requiring a dedicated tool for operation pattern creation.

  -By checking the validity of the structure of the created operation pattern before automatic operation, unexpected pattern data will not appear during test execution.

  -The conventional CSV format operation pattern can express only a two-dimensional data structure, but the XML schema can express a multi-dimensional data structure with a nested structure, so that it can be designed in the same way as a database.

(2) Change of operation pattern The operation pattern is changed by changing the corresponding part of the operation pattern of the XML document acquired in the creation procedure (S2) of FIG. It is possible to obtain operation pattern data for which the validity check has been performed by executing the process of S8).

(3) Operation pattern structure change The operation pattern structure change is performed by changing the corresponding part of the operation pattern structure of the XML schema document acquired in the creation procedure (S1) of FIG. 1 and acquiring it in (S2) of FIG. If the corresponding part of the operation pattern of the XML document is changed, the XML schema document and the XML document of these operation patterns are acquired, the processes of (S3) to (S8) are executed, and the operation pattern structure and the operation pattern are valid. It is possible to obtain driving pattern data that has undergone a sex check.

  The change of the above operation pattern and operation pattern structure has the following advantages.

  -To change the structure of the operation pattern, you can change the tag name or add a new tag.

  -Since the operation pattern can be described in an XML document, a general-purpose text editor can be used without requiring a dedicated tool when the operation pattern is changed.

  -By automatically generating an operation pattern interpretation program from an XML schema document that defines the structure of the operation pattern, it is not necessary to redesign the operation pattern interpretation program when the structure of the operation pattern is changed.
