The present invention relates to an analysis system for analyzing intake gas or
exhaust gas of an internal combustion engine and to an information processing device to
be used therefor5 .
Background Art
An analysis system for an internal combustion engine of this type is composed
10 of one or more analysis devices and an information processing device for managing
these analysis devices. And multi-pieces of analysis-associated data such as
measurement data and setting data are given and received between each of the analysis
devices and the information processing device.
15 Unit systems for use in these multi-pieces of analysis-associated data are
different according to users. For example, there may be some cases of using unit
systems compliant with standards defined in countries or regions, or there may be also a
case of using an originally own unit system.
20 Therefore, conventionally, there has been performed, for example, a work such
that a unit system of analysis-associated data for use in an analysis system is previously
set to be one used in a shipping destination user. Also, for example, in the case where
certification tests in various countries are performed using this analysis system, there
may be a case that the unit system of the analysis-associated data is changed by a user
25 side every certification test in different countries.

However, even the analysis-associated data pertaining to one analysis device
may be up to multi-pieces, and there may be a case where various types of analysis
devices are used in one laboratory, In such a case, there is a problem that it takes much
time and effort to set the unit syste5 m.

Description of Embodiments
The following describes one embodiment of the present invention referring to
the accompanying drawings.
5
As shown in Fig. 1, an analysis system 1 pertaining to the present embodiment
is intended to calculate an analysis component concentration, fuel consumption and the
like by sampling exhaust gas of a vehicle internal combustion engine. This analysis
system 1 includes a plurality of exhaust gas analysis devices 2 and an information
10 processing device 3 for receiving measurement data measured by these analysis devices
2 or sending setting data to the analysis devices 2 to thereby integrally manage the
analysis devices 2. It is noted that the measurement data and setting data etc. given
and received between each of the analysis devices 2 and the information processing
device 3 are referred to as “analysis-associated data” hereinafter.
15
The analysis devices 2 include, for example, a CVS device, EGR measurement
device, exhaust gas comprehensive analysis device including a plurality of exhaust gas
analysis units therein or the like and each of the analysis devices 2 outputs multi-pieces
of measurement data. It is noted that, for convenience of management by the
20 information processing device 3, the plurality of analysis devices may be recognized as
one analysis device or may be vice versa. Also, the analysis devices may be
configured as a hierarchically-structured management system. In the case of a
hierarchically-structured configuration, various settings and the like as to be described
later for the analysis devices in upper layers can be commonly effected to the analysis
25 devices in lower layers. Meanwhile, the settings and the like as to be described later
8
can be effected only for some of the analysis devices belonging to the lower layers.
The information processing device 3 is configured of, for example, a CPU (not
shown), memory, A/D converter, D/A converter, communication interface, input means
(such as a mouse and keyboard), display and the like. The CPU and periphera5 l
equipment thereof are cooperated in accordance with a predetermined program stored in
the memory, thereby performing functions as a unit series data storage part 31, selection
input receiving part 32, data output part 33, unit series data editing part 34, available
unit storage part 35, unit editing part 36, analysis device management part 37 and the
10 like.
Next, the following describes a configuration of the analysis system 1
mentioned above, also serving as a detailed description of each of the parts.
15 The analysis-associated data described above is received by the data output part
33 via the analysis device management part 37 and is, for example, outputted to be
displayed on the display or outputted to be filed. In this embodiment, an operator can
set a unit of values of the outputted analysis-associated data using the input means.
20 Next, the setting of a unit is described in detail.
First, the selection input receiving part 32 displays a unit setting window 4
shown in Fig. 5 on the display referring to the unit series data storage part 31.
25 More specifically, as shown in Fig. 2, multi-pieces of unit series data are stored
9
in the unit series data storage part 31 with tie association in each of the analysis devices
2. As shown in Fig. 3, each unit series data includes a unit series name for identifying
the unit series data and, in addition thereto, one or more analysis-associated data names
(denoted as Data Category in Fig. 5) for identifying the analysis-associated data as
substantive contents. In association with each of the analysis-associated data na5 me,
the unit series data further includes: a physical phenomenon type name (denoted as Unit
Family in Fig. 5) indicating a physical phenomenon type such as a weight, length,
volume and temperature; a unit name (denoted as Unit in Fig. 5) indicating the unit of
the values of the outputted analysis-associated data; and a number of output digits
10 (denoted as Sig. Digit in Fig. 5).
Thus, the unit setting window 4 is provided with: an analysis device name
display column 41 for switchably displaying the analysis device name; a unit series
name display column 42 for selectably displaying the unit series names in a list which
15 can be used in the selected analysis device 2; a unit series data contents display column
43 for displaying the contents of the selected unit series data in a list, and the like. The
selection input receiving part 32 displays: the analysis device names stored in the unit
series data storage part 31 described above in the analysis device name display column
41; the unit series names in the unit series name display column 42; and the
20 analysis-associated data names, physical phenomenon type names, unit names, and the
output digit numbers in the unit series data contents display column 43.
In the unit setting window 4 displaying the above items in this way, regarding
the analysis device 2 displayed in the analysis device name display column 41, it is
25 indicated that the unit series data denoted to be active in the unit series name display
10
column 42 is under selection. In the example shown in Fig. 5, the unit series data of
the unit series name called Metric is selected for the analysis device named as CVS.
In this state, when an operator selects another unit series name displayed in the
unit series name display column 42 using, for example, a mouse, the contents of the 5 unit
series data is displayed in a list in the unit series data contents display column 43.
Then, although not shown, when a deciding operation is performed by the operator, the
selection input receiving part 32 receives the selected unit series data.
10 Then, the data output part 33 displays the values of the analysis-associated data
in each unit specified for the selected unit series data, for example, on the display,
respectively (not shown).
Further, in the present embodiment, the contents of the unit series data storage
15 part 31 can be edited. For that purpose, the operator performs an appropriate operation
such as clicking an EDIT button of the unit setting window 4. Then, a unit series data
editing window 5 shown in Fig. 6 is displayed so as to be able to change the contents of
each unit series data associated with each of the analysis devices 2, i.e., the
analysis-associated data name, physical phenomenon type name, unit name and number
20 of output digits. Then, the unit series data editing part 34 reads the contents selected
by the operator in this operation and changes the contents of the unit series data storage
part 31. Further, in Fig. 6, it is configured to be able to select the unit name and the
number of output digits from among a previously registered list.
25 In addition, the unit series data can be increased by clicking an ADD button
11
shown in Fig. 5, and the unit series data can be also deleted by clicking a DELETE
button shown in Fig. 5.
In addition, the contents of this available unit storage 35 can be also edited by
an operator. In that case, an available unit editing window 6 shown in Fig. 7 5 is
displayed by an appropriate operation by the operator. A physical phenomenon type
name list column 61 is provided in this available unit editing window 6, and upon
selection of one physical phenomenon type name in the list column 61, one or more unit
names available in the selected physical phenomenon type are displayed in a list in an
10 available unit column 62. Among the listed unit names, those unit names having
checked in check boxes are available, and upon taking off a check, the corresponding
unit name can be made unavailable. A scale of the unit is also editable. The unit
editing part 36 reads this operation and edits the available unit storage part 35.
15 With this configuration, since each unit of the values of a series of
analysis-associated data used in a certain analysis device can be collectively set and
changed by simply selecting any of the unit series data associated with the analysis
device, it is possible to greatly reduce the effort of the unit setting.
20 Further, since it is possible to add, change or delete a unit any time in
accordance with a need of an operator using the unit series data editing part 34 and unit
editing part 36, a flexible operation becomes possible.
In addition, the present invention should not be limited to the above
25 embodiment, and various modifications such as configurations of the respective
12
windows are possible within the scope unless departing from the intended spirit thereof.
