Abstract

A work management system includes a calibration instruction recorder and a work instruction recorder, wherein the calibration instruction recorder receives and stores a calibration work record of the calibration work from a first terminal, stores the calibration work record, stores device identification information included in the calibration work record as the device identification information, and stores “usable” or “not usable” as use propriety of the device, depending on whether the calibration determination result included in the calibration work record is “appropriate” or “inappropriate”. The work instruction recorder receives a work request from a second terminal and transmits the work contents to the second terminal when the use propriety of the device is “usable” and transmits an error notification to the second terminal when the use propriety of the device is “not usable”. The device is used for the work performed by the worker as a user of the second terminal.

First claim

What is claimed is:

1 . A work management system comprising:
a calibration instruction computer and a work instruction computer connected to a calibration instruction computer via a network, wherein the calibration instruction computer is programmed to: access a calibration instruction database that stores calibration work identification information, identification information on a device to be calibrated, calibration work contents, and calibration worker identification information, access a calibration record database that stores the calibration work identification information, the device identification information, the calibration worker identification information, date and time of calibration work, and a calibration determination result, and access a device information database that stores the identification information on the device and use propriety of the device, wherein the work instruction computer is programmed to: access a work instruction database that stores work identification information, work contents, worker identification information, and the identification information on the device used, access a work record database that stores the work identification information, the worker identification information, and date and time of work, and access the device information database, wherein the calibration instruction computer is programmed to execute processing including: receiving a calibration work request from a first terminal, acquiring identification information on the device to be calibrated by a calibration worker who uses the first terminal and the calibration work contents, and transmitting the identification information and calibration work contents to the first terminal, receiving a calibration work record of the calibration work from the first terminal and storing the calibration work record in the calibration record database, storing device identification information included in the calibration work record as the device identification information in the device information database, and storing “usable” or “not usable” as use propriety of the device in the device information database, depending on whether the calibration determination result included in the calibration work record is “appropriate” or “inappropriate”, and wherein the work instruction computer is programmed to execute processing including: receiving a work request from a second terminal, acquiring identification information on the work performed by the worker who uses the second terminal, the work contents, the worker identification information, the identification information on the device used, and the use propriety of the device used, transmitting the work contents and the identification information on the device used to the second terminal when the use propriety of the device is “usable”, receiving a work record of the work from the second terminal, and storing the work record in the work record database, and transmitting an error notification to the second terminal when the use propriety of the device is “not usable”.

2 . The work management system according to claim 1 ,
wherein the work instruction computer is programmed to: access a work instruction master database that stores work master identification information, the work contents, and the identification information on the device used, receive a work plan registration request including the work master identification information and the worker identification information from a third terminal, acquire a use propriety of the device used, store work contents corresponding to the work master identification information, the worker identification information, and the identification information on the device used in the work instruction database when the use propriety of the device is “usable”, and transmit an error notification to the third terminal when the use propriety of the device is “not usable”.

3 . The work management system according to claim 2 ,
wherein the device information database further includes an expiration date indicating a valid expiration date when the use propriety is “usable”, wherein the calibration instruction computer is programmed to store the expiration date determined by a predetermined method in the device information database when storing the use propriety in the device information database, wherein the work instruction computer is programmed to: acquire the use propriety and the expiration date of the device used when receiving the work plan registration request further including the date and time of work from the third terminal, store work contents corresponding to the work master identification information, the worker identification information, and the identification information on the device used in the work instruction database, when the use propriety of the device is “usable” and the date and time of work is before the expiration date, and transmit an error notification to the third terminal when the use propriety of the device is “not usable” or the date and time of work is past the expiration date.

4 . A calibration work management server comprising:
a calibration instruction computer, wherein the calibration instruction computer is programmed to access: a calibration instruction database that stores calibration work identification information, identification information on a device to be calibrated, calibration work contents, and calibration worker identification information, a calibration record database that stores the calibration work identification information, the device identification information, the calibration worker identification information, date and time of calibration work, and a calibration determination result, and a device information database that stores the device identification information and use propriety of the device, and wherein the calibration instruction computer is programmed to: receive a calibration work request from a first terminal, acquire identification information on the device to be calibrated by a calibration worker who uses the first terminal and the calibration work contents, and transmitting the identification information and calibration work contents to the first terminal, receive a calibration work record of the calibration work from the first terminal and storing the calibration work record in the calibration record database, store device identification information included in the calibration work record as the device identification information in the device information database, and store “usable” or “not usable” as use propriety of the device in the device information database, depending on whether the calibration determination result included in the calibration work record is “appropriate” or “inappropriate”, wherein the device information database is accessed by a work management server, wherein the work management server includes a work instruction computer that is programmed to access; a work instruction database that stores work identification information, work contents, worker identification information, and the identification information on the device used, and a work record database that stores the work identification information, the worker identification information, and date and time of work, and wherein the work instruction computer is programmed to: receive a work request from a second terminal, acquire identification information on the work performed by the worker who uses the second terminal, the work contents, the worker identification information, the identification information on the device used, and the use propriety of the device used, transmit the work contents and the identification information on the device used to the second terminal when the use propriety of the device is “usable”, receiving a work record of the work
