Abstract
To provide a monitoring device, a machine tool, and a monitoring system capable of collecting data efficiently required for examining an alarm. A monitoring device is connected to multiple machine tools through a network. The monitoring device comprises: a monitoring unit that monitors the occurrence of an alarm in the machine tools; an acquisition unit that acquires a set of measurement target data items responsive to an alarm from a database on the occurrence of the alarm; and a collection unit that sets the set of measurement target data items in the multiple machine tools, and collects data measured by following the setting.
Claims3
A monitoring device connected to multiple machine tools through a network, the monitoring device comprising:
- a monitoring unit that monitors the occurrence of an alarm in the machine tools;
- a counting unit that counts the number of time each alarm occurred;
- an acquisition unit that acquires a set of measurement target data items responsive to an alarm from a database on the occurrence of the alarm;
- a selection unit that selects a machine tool as a measurement target in which the set of measurement target data items is to be set based on a state of occurrence of the same alarm determined using a result of the counting by the counting unit;
- and
- a collection unit that sets the set of measurement target data items in the machine tool selected by the selection unit, and collects data measured by following the setting,
- wherein, if an alarm occurred at a frequency less than a predetermined frequency, the selection unit selects all the machine tools of the same type classified in advance.
A monitoring system comprising a monitoring device and multiple machine tools connected to the monitoring device through a network,
- the monitoring device comprising:
- a monitoring unit that monitors the occurrence of an alarm in the machine tools;
- a counting unit that counts the number of times each alarm occurred;
- an acquisition unit that acquires a set of measurement target data items responsive to an alarm from a database on the occurrence of the alarm;
- a selection unit that selects a machine tool as a measurement target in which the set of measurement target data items is to be set based on a state of occurrence of the same alarm determined using a result of the counting by the counting unit and
- a collection unit that sets the set of measurement target data items in the machine tool selected by the selection unit, and collects data measured by following the setting,
- wherein, if an alarm occurred at a frequency less than a predetermined frequency, the selection unit selects all the machine tools of the same type classified in advance,
- the machine tools each comprising:
- a notification unit that notifies the monitoring device of an alarm having occurred in the machine tool;
- a setting unit that receives the set of measurement target data items from the monitoring device, and makes setting about the set of measurement target data items;
- and
- a transmission unit that transmits data measured by following the setting about the set of measurement target data items to the monitoring device.
