Abstract:
To collect time-adjusted data efficiently.SOLUTION: A data collection system 100 comprises a data collection device 1 for detecting a trigger and a data collection device 1 for inquiring about a trigger. The data collection device 1 for detecting a trigger comprises a trigger detection unit 15 for monitoring data acquired by a data acquisition unit 11. When a trigger condition is satisfied, an elapsed time measuring unit 16 measures an elapsed time Ttrg after the trigger is established. When a command reception unit 17 receives a command inquiring about the trigger from a second data collection device 1, an elapsed time notification unit 18 transmits the elapsed time Ttrg to the second data collection device 1. The second data collection device 1 calculates the occurrence time of the trigger based on the elapsed time Ttrg and a reception time Trcv of the elapsed time Ttrg.SELECTED DRAWING: Figure 6
