Abstract

A tool system includes a tool and an external system. The tool includes a first communications interface. The first communications interface transmits result information, including a work order number, to the external system with progress of work. The external system includes a second communications interface. The second communications interface receives the result information transmitted from the tool. The external system makes a storage device store the result information received by the second communications interface. At least one of the tool or the external system further includes a determiner. The determiner determines, based on progress information indicating the progress of the work being performed by the tool and the result information stored in the storage device, what part of the result information the second communications interface has failed to receive.

Claims (41)

1 . A tool system comprising:

a tool being configured to perform a fastening operation and including a first communications interface; and

an external system including a second communications interface,

the first communications interface being configured to transmit result information, including a fastening torque of the fastening operation and including a work order number, to the external system with progress of the work,

the second communications interface being configured to receive the result information from the tool,

the external system being configured to make a storage device store the result information received by the second communications interface,

at least one of the tool or the external system further including a processor,

the processor being configured to determine, based on progress information indicating the progress of the work being performed by the tool and the result information stored in the storage device, what part of the result information the second communications interface has failed to receive.

2 . The tool system of claim 1 , wherein

the external system includes the processor, and

the processor is configured to determine, based on the progress information transmitted from the first communications interface to the second communications interface and the result information stored in the storage device, what part of the result information the second communications interface has failed to receive.

3 . The tool system of claim 2 , wherein

the processor is configured to request the tool to transmit the part of the result information that the processor determines the second communications interface has failed to receive.

4 . The tool system of claim 2 , wherein

the processor is configured to detect any change in a status of wireless communication with the tool, and

the processor is configured to, when the communications detector has detected a recovery from a communication breakdown, determine what part of the result information the second communications interface has failed to receive.

5 . The tool system of claim 2 , wherein

the processor is configured to determine whether a series of predetermined work process steps to be performed by the tool has been finished, and determine, when deciding that the series of predetermined work process steps have been finished, what part of the result information the second communications interface has failed to receive.

6 . The tool system of claim 2 , wherein

the second communications interface is configured to transmit a work stop signal to the tool as needed, and

the processor is configured to, when the second communications interface has transmitted the work stop signal, determine what part of the result information the second communications interface has failed to receive.

7 . The tool system of claim 1 , wherein

the processor is configured to decide, based on the result information stored in the storage device and information about a series of predetermined work process steps, whether the series of predetermined work process steps has been finished.

8 . The tool system of claim 1 , wherein

the first communications interface is configured to transmit, to the external system, the part of the result information that the processor determines the second communications interface has failed to receive.

9 . The tool system of claim 1 , wherein

the result information includes a measured value of the fastening torque associated with the work order number, and

the processor is configured to determine that the second communications interface has failed to receive the measured value of the fastening torque associated with a specific work order number when the result information stored in the storage device lacks the measured value corresponding to the specific work order number despite the progress information indicating that the work associated with the specific work order number has been performed.

10 . An external system comprising:

a communications interface configured to receive, from a tool configured to perform a fastening operation, result information including a fastening torque of the fastening operation and including a work order number,

a storage device configured to store the result information received by the communications interface; and

a processor configured to determine, based on progress information indicating progress of the work being performed by the tool and the result information stored in the storage device, what part of the result information the communications interface has failed to receive.

11 . The external system of claim 10 , wherein

the result information includes a measured value of the fastening torque associated with the work order number, and

the processor is configured to determine that the communications interface has failed to receive the measured value of the fastening torque associated with a specific work order number when the result information stored in the storage device lacks the measured value corresponding to the specific work order number despite the progress information indicating that the work associated with the specific work order number has been performed.

12 . A determination method for use in a tool system, the tool system including a tool configured to perform a fastening operation and an external system, the tool being configured to transmit result information, including a fastening torque of the fastening operation and including a work order number, to the external system with progress of the work, the external system being configured to receive the result information from the tool and make a storage device store the result information, the determination method including:

determining, based on progress information indicating the progress of the work being performed by the tool and the result information stored in the storage device, what part of the result information the external system has failed to receive.

13 . A non-transitory storage medium storing thereon a program designed to cause one or more processors to perform the determination method of claim 12 .

14 . The determination method of claim 12 , wherein

the result information includes a measured value of the fastening torque associated with the work order number, and

the determining comprises determining that the external system has failed to receive the measured value of the fastening torque associated with a specific work order number when the result information stored in the storage device lacks the measured value corresponding to the specific work order number despite the progress information indicating that the work associated with the specific work order number has been performed.
