Data collection device
A data collection device includes: a setting information storage unit storing setting information respectively associated with a plurality of cooperation levels set in accordance with a degree of cooperation with a higher system; a life-and-death monitoring unit monitoring a state of the cooperation with the higher system; a cooperation level determination unit determining the level of the cooperation with the higher system; a setting switching unit switching an operation setting of each function in accordance with the setting information corresponding to the cooperation level; a data collection unit collecting data in accordance with the operation setting switched by the setting switching unit; a data processing unit executing predetermined processing with respect to the data; and a data output unit outputting the data to a designated output destination.
1. A data collection device configured to, via a computer communication network, collect data from an industrial machine and output the data to a higher system, the data collection device comprising:
a setting information storage unit storing setting information respectively associated with a plurality of cooperation levels set in accordance with a degree of cooperation with the higher system;
a life-and-death monitoring unit monitoring a state of the cooperation with the higher system via the computer communication network;
a cooperation level determination unit determining a cooperation level of the plurality of cooperation levels with the higher system based on the state of the cooperation with the higher system;
a setting switching unit
reading the setting information corresponding to the cooperation level determined by the cooperation level determination unit from the setting information storage unit and
switching an operation setting of each function in accordance with the read setting information to allocate resources for cooperation with the higher system;
a data collection unit collecting the data from the industrial machine via the computer communication network in accordance with the operation setting switched by the setting switching unit;
a data processing unit executing processing, designated by the operation setting switched by the setting switching unit, on the data collected by the data collection unit, by using the resources allocated for cooperation with the higher system; and
a data output unit outputting the data processed by the data processing unit via the computer communication network to an output destination including the higher system designated by the operation setting switched by the setting switching unit.
2. The data collection device according to claim 1 , wherein
the setting information stored in the setting information storage unit is further associated with a plurality of operation states of the industrial machine,
the data collection device further comprises a state monitoring unit monitoring each of the plurality of operation states of the industrial machine, and
the setting switching unit
reads the setting information corresponding to the cooperation level determined by the cooperation level determination unit and an operation state of the plurality of operation states of the industrial machine specified by the state monitoring unit from the setting information storage unit and
switches the operation setting of each function in accordance with the read setting information.
3. The data collection device according to claim 1 , wherein
the data collection device comprises a plurality of operation modes including at least a single operation mode and a cooperative operation mode,
at least the setting switching unit functions in the cooperative operation mode, and
the data collection device further comprises a cooperation request standby unit waiting for a cooperation request from the higher system and switching the operation mode to the cooperative operation mode in response to the cooperation request being received.
4. The data collection device according to claim 1 , wherein an operation of the function in which the setting switching unit switches the operation setting includes at least one of whether or not to perform data collection from the industrial machine, selection of a data item acquired from the industrial machine, a cycle of data acquisition from the industrial machine, selection of a transmission or storage destination of acquired data, or data processing including compression or thinning of the acquired data.
