[0021]

1 and 2 are views for explaining a first embodiment of the present invention. FIG. 1 is a view showing the processing contents of a computer 7 of a car vaporized gas measuring apparatus 1 shown in FIG. An example is shown in the test results. In the following description, with reference to FIG. 5 as well, the members denoted by the same reference numerals as those in the description of the conventional example are the same or equivalent members, and the description thereof will be omitted to avoid duplicate description.

FIG. 1 shows a computer 7 of the test apparatus 1.
It is a figure explaining the flow of the processing which. In Figure 1, the internal S ₁ step of inputting a measured value indicating the state of the SHED2 from each controller 4,5 to input measurements from the gas analyzer 6, S _2, all of a single said measurements the step of converting into a unit, step S ₃ is for outputting a test result by computing the measured value converted into internal units, S
₄ step of determining a unit used for display of the test results, S ₅ is a step of outputting the test results expressed in the internal units. That is a computing means programmed to carry out the process of the step S ₃ calculates the arithmetic processing to the test results in a single internal unit system the measurements from the analyzer 6.

In this example, in step S ₂ , for example, the unit of distance is m (meter), the unit of pressure is Pa (Pascal), the unit of temperature is K (Kelvin),
The unit of weight is g (gram) and is uniformly converted and calculated. The arithmetic means shown in the step S ₃ is output as the test results obtained by processing with one internal unit test results file R for example to the hard disk.

Mt is a plurality of macro programs M which the computer 7 has, for example, recorded in its hard disk (computer-readable storage medium).
_Is a table of _{1,2,3, ..} , each macro program M
_{1,2,3, ..} of which are appropriately selected in accordance with the test result of the content or the unit to be output is selected by step S _4. The contents and units of the test results to be output can be changed according to the regulations in each region to be tested and the preference of the user, and a plurality of macro programs for obtaining possible outputs are prepared in advance. I have.

[0025] That is, selection of the unit by the step S ₄ is singled out appropriate macro program from among the tables Mt, output macro program file M
This is performed by, for example, outputting to a hard disk as o. The selection of the unit by the step S ₄ may be performed at a faster step. Further, it goes without saying that it is possible to change the contents of the calculation process in the step S ₃ in accordance with the content of the regulation.

Next, the computer 7 executes step S
_As shown in FIG. ₅ , the application program C (for example, spreadsheet software) is started, and the macro program Mo and the test result file R are specified in the application program C. That is, not only the test results to the application program C, by passing with a macro program defining the output method, the application program C, the test result is read files R in Step C _1, to read a macro program files R in Step C ₂ Can be.

[0027] By executing the read macro program as shown in Step C _3, it is possible to convert the desired test results in the desired units. That is, an output means and application programs C performing unit selection by the step S ₄ outputs at desired units tailored to restriction content by unit converts the test results.

In the case of this example, the unit of temperature is changed from K to ° C. (degree C) and the unit of pressure is Pa
To kPa, and the unit of distance is converted from m to km. That is, it is easier for the user to understand the unit C which is always used than the unit K which is unfamiliar. Further, when the size in a specific unit is determined by the regulation, it is possible to easily determine whether or not the size is within the range of the regulation by outputting the unit in accordance with the content of the regulation. Further, by adjusting the number of digits to be displayed according to the content of the regulation, the determination can be made more easily.

Here, as the application program C, numerical data is displayed in a good format such as text display or graph display as in commercially available spreadsheet software or the like.
With one having a function of printing, it can be output by the format may display 7a or printer simply converted test results as shown in step C _4. Further, if the spreadsheet software used as the application program C has a macro function, the present invention can be efficiently and easily implemented. As the spreadsheet software, for example, by using generally widely available commercial software such as Microsoft Excel, operability,
This is advantageous in terms of data compatibility and the like.

The application program C
It is needless to say that may be separately programmed for the test apparatus 1. In this case, the application program C does not need to use the above-described macro program Mo, but may be a program that allows a desired unit conversion by simply specifying a unit to be output.

As in the present invention, by uniformly converting all inputs into a single internal unit, step S ₃
The calculation formula described in the program for calculating the test results shown in (1) can be made as simple as the formula. Also,
If only one program for performing arithmetic processing is assembled, it can be displayed in various unit systems. That is, since a large number of units are not used in the arithmetic processing, the measurement value is not incorrectly calculated and the calculation error can be suppressed as much as possible. That is, the program development and the correction can be performed quickly.

[0032] Figure 2 shows an example of the output sheet P ₁ is an output example of the test results. As shown in FIG. 2, the test results include, for example, a test target display section 8 for displaying a test target such as a test date and a vehicle name, a test setting display section 9 for displaying an SHED volume and the like, when the test is started. It has a test environment display unit 10 for displaying a test environment from the end to the end, and a test result display unit 11 for displaying test results.

Each of the display sections 8 to 11 displays an item name N and an output O corresponding to each item, and includes a test setting display section 9, a test environment display section 10, and a test result display section 11.
In, the output is divided into a numerical value O ₁ indicating the measured value or test result of each item N and its unit O ₂ and displayed. The layout such as the arrangement order of these display units 8 to 11 is determined by the output macro program Mo passed to the application program C shown in FIG. 1, and can be arbitrarily changed by changing the macro program Mo. It is possible.

The display method of the numerical value O ₁ and the unit O ₂ is also determined by the macro program Mo. In this example, the unit representing volume is m ³ , the unit representing temperature is ° C., the unit representing pressure is kPa, and the unit representing concentration is p.
pm, unit of weight is g, unit of distance is km
And

As described above, since all of the unit conversions are performed by the application program C, no matter what unit is used for display, only the macro program Mo changes with the unit change. is there. In other words, no matter which unit system is used for output, the program for performing the calculation processing of the measured values and outputting the test results (step S
_2, since the operation in the corresponding) in only the internal units S _3, a program for outputting a test result can be performed a common process regardless of the output units.

Therefore, since the unit is common at the time of arithmetic processing, program development can be simplified. That is, development, maintenance, and improvement can be easily performed while minimizing the occurrence of program errors.

In this example, since a plurality of macro programs M _{1, 2, 3,... Are} prepared in order to display a unit system that can be considered in advance, the user can select the unit system to be used at the time of output. By simply selecting a macro program, it is possible to output test results in a desired unit system very easily.

[0038] In the above example, although the output of the test result shows an example of performing by printing on a recording sheet P _1, the present invention is not limited thereto. That is, you may output by displaying a test result in a graph. In this case, it is necessary for the application program C to have a graph display function, whereby a well-formed output can be obtained very easily. Also,
The output method is not limited to printing. That is, it may be displayed on the display 7a (see FIG. 5).

[0039] FIG. 3 is a diagram showing an output example by the recording paper P ₂ in the case of changing the macro program Mo be processed by the application program C. In this example, portions denoted by the same reference numerals as those in FIG. 2 are the same or equivalent portions, and thus detailed description thereof will be omitted, and redundant description will be avoided.

In this example, the unit representing the volume is f
t ³ , unit representing temperature is ° F, unit representing pressure is m
mAq, the unit representing the concentration is ppm, the unit representing the weight is g, and the unit representing the distance is Mile. The unit O ₂ for each entry N is in accordance with the restriction content which is determined in the region of the tests, and displays a unit system used to determine the regulatory limits.

Therefore, the user can directly compare the numerical value O ₁ of the output paper P ₁ or P ₂ according to the regulation content with the regulation value, and can easily determine whether or not the regulation content is exceeded. it can. Further, it is possible to display the numerical value O ₁ so as to have an appropriate value without being too large or too small.

It should be noted that the display unit O ₂ described above may be displayed not only in accordance with the contents of regulation but also in accordance with the user's preference by converting it into a unit required by the user. In this case, the test results can be easily understood by the user and the work efficiency can be improved.

FIG. 4 shows a plurality of measured values or test results.
Output paper P when outputting in units of _ThreeFIG.
Also in this case, the contents of the macro program Mo must be changed.
And can be dealt with. In this example,
In the following description, the same reference numerals as those in FIGS.
The duplicate description is omitted.

In this example, the unit representing the volume is m ³ and ft ³ , the unit representing the temperature is ° C., and the unit representing the pressure is k.
The unit representing Pa and mmAq, the unit representing the concentration is represented by ppm, the unit representing the weight is represented by g, and the unit representing the distance is represented by km and miles. That is, the unit O ₂ of each item N is adjusted in accordance with the regulation contents set in the region where the test is conducted.
In addition to displaying in the unit system used to determine the regulation value, it is also possible to simultaneously display in another unit that is easy for the user to use, or to compare with another regulation content. Operability can be further improved.

In each of the above-described examples, the macro program M for converting the measured values and test results into units and outputting them to the application program C in accordance with the contents of regulation.
_Although an example of recording _{1, 2, 3, ... On} the hard disk in the computer 7 is shown as an example, the present invention does not limit the medium on which the macro programs M _{1, 2, 3,.} . For example, it goes without saying that the program may be recorded on a CD-ROM, a floppy (registered trademark) disk, or the like so that a new macro program can be added in accordance with a change in the regulation content.

[0046]

As described above, according to the present invention,
Since the arithmetic means performs arithmetic processing in a single internal unit system, the program for calculating the test results is simplified, so that the development, maintenance and improvement of the program becomes simpler and errors are reduced. . Further, the output of the test result can be converted into a unit requested by the operator by the application program and displayed, so that the test result can be easily viewed.

When a computer-readable storage medium is provided in which a plurality of macro programs for converting the test results into required unit systems in accordance with the contents of the regulation are prepared and recorded, the regulation selected by the user is used. By the test apparatus selecting an appropriate macro program according to the contents of the above, the output method of the test result can be changed very easily.
