Abstract

To effectively utilize work information acquired by maintenance of an instrument in a plant, an apparatus is provided, which includes an acquisition unit that acquires work information about at least one of a calibration or an adjustment performed on the instrument in a plant; an extraction unit that extracts a plurality of data elements to be included in output information having a predetermined output format from the work information; and a generation unit that generates the output information from the plurality of data elements.

First claim

What is claimed is:

1. An apparatus comprising: an acquisition unit configured to acquire a plurality of calibration work information about a calibration of one or more instruments performed at different dates and times by a maintenance apparatus configured to perform the calibration of the one or more instruments, each of the one or more instruments being a measuring device in a plant; an extraction unit configured to extract, from the calibration work information, a plurality of data elements including the instrument identification information and the calibration result from the calibration work information that is related to the maintenance work performed for multiple times on each of the one or more instruments, the plurality of data elements having a predetermined output format; a generation unit configured to calculate a measurement error for each of the one or more instruments based on the calibration result from the plurality of data elements in a period of time and to generate an output information including an instrument identification information and said measurement error; a storage processing unit configured to store, on a storage device, the output information generated by the generation unit; and a display processing unit configured to acquire the output information from the storage processing unit and to display (1) a change with time of the measurement error of the one or more instruments presenting a tendency of aging degradation of the measurement error, per calibration points, of the one or more instruments, or (2) a change with time of a maximum measurement error of the one or more instruments, presenting the tendency of the aging degradation of the maximum measurement error of each of the one or more instruments, wherein the calibration is an adjustment among 5 measuring points acquired using a 5-point calibration, in the order of a first calibration measuring point at a lower limit point of a measurement range of the one or more instruments, a second calibration measuring point at a middle point in the measurement range, and a third calibration measuring point at an upper limit point of the measurement range, the first second and third calibration measuring points having been measured in order while increasing a parameter to be measured, thereafter a fourth calibration measuring point being measured at the middle point in the measurement range and a fifth calibration measuring point being measured at the lower limit point of the measurement range, the fourth and fifth calibration measuring points having been measured while decreasing the parameter to be measured.

2. The apparatus according to claim 1 , wherein
the extraction unit stores a plurality of input formats corresponding to a plurality of types of maintenance apparatuses; and
extracts the plurality of data elements from the calibration work information by using an input format corresponding to a type of the maintenance apparatus that is targeted from the plurality of input formats.

3. The apparatus according to claim 1 , wherein
the generation unit generates the output information by arranging the plurality of data elements in an order defined by the output format.

4. The apparatus according to claim 1 , wherein
the generation unit causes a result acquired by performing an operation defined by the output format on at least one data element of the plurality of data elements to be included in a part of the output information.

5. The apparatus according to claim 1 , wherein
the generation unit generates the output information including a worker who performs the calibration and a working time required to perform the calibration; and
the display processing unit performs a process of displaying, on the display device, the working time for each worker.

6. A non-transitory computer-readable recording medium recording a program that is executed by a computer and causes the computer to function as: an acquisition unit configured to acquire a plurality of calibration work information about a calibration of one or more instruments performed at different dates and times by a maintenance apparatus configured to perform the calibration of the one or more instruments, each of the one or more instruments being a measuring device in a plant; an extraction unit configured to extract, from the calibration work information, a plurality of data elements including the instrument identification information and the calibration result from the calibration work information that is related to the maintenance work performed for multiple times on each of the one or more instruments, the plurality of data elements having a predetermined output format; a generation unit configured to calculate a measurement error for each of the one or more instruments based on the calibration result from the plurality of data elements in a period of time and to generate an output information including an instrument identification information and said measurement error; a storage processing unit configured to store, on a storage device, the output information generated by the generation unit; and a display processing unit configured to acquire the output information from the storage processing unit and to display a change with time of the measurement error of the one or more instruments presenting a tendency of aging degradation of the measurement error, per calibration points, of the one or more instruments, or a change with time of a maximum measurement error of the one or more instruments, presenting the tendency of the aging degradation of the maximum measurement error of each of the one or more instruments, wherein the calibration is an adjustment among 5 measuring points acquired using a 5-point calibration, in the order of a first calibration measuring point at a lower limit point of a measurement range of the one or more instruments, a second calibration measuring point at a middle point in the measurement range, and a third calibration measuring point at an upper limit point of the measurement range, the first second and third calibration measuring points having been measured in order while increasing a parameter to be measured, thereafter a fourth calibration measuring point being measured at the middle point in the measurement range and a fifth calibration measuring point being measured at the lower limit point of the measurement range, the fourth and fifth calibration measuring points having been measured while decreasing the parameter to be measured.

7. The non-transitory computer-readable recording medium according to claim 6 , wherein
the extraction unit stores a plurality of input formats corresponding to a plurality of types of maintenance apparatuses; and
uses an input format according to a type of the maintenance apparatus that is targeted from the plurality of input formats and extracts the plurality of data elements from the calibration work information.

8. The non-transitory computer-readable recording medium according to claim 6 , wherein
the generation unit arranges the plurality of data elements in an order defined by the output format and generates the output information.

9. The non-transitory computer-readable recording medium according to claim 6 , wherein
the generation unit causes a result acquired by performing an operation defined by the output format on at least one data element of the plurality of data elements to be included in a part of the output information.

10. A method comprising: acquiring, by a device, a plurality of calibration work information about a calibration of one or more instruments performed at different dates and times by a maintenance apparatus configured to perform the calibration of the one or more instruments, each of the one or more in
