PROBLEM TO BE SOLVED: To provide a log data collection device, a log data collection system, and a log data collection method that can simply collect log data without depending on radio communication.SOLUTION: A log data collection device 100 comprises: a log data generation unit 101 for generating an output result from a sensor as log data; a log data storage unit 102 for storing the generated log data; a log data control unit 103 for performing control to obtain the log data from the log data generation unit to store it in the log data storage unit; a barcode generation unit 104 for generating a barcode by transforming the log data into barcode; and a display unit 105 for displaying the barcode generated by the barcode generation unit. The log data control unit obtains log data from the log data generation unit per elapse of a prescribed time to store it in the log data storage unit, and reads log data stored in the log data storage unit to transmit it to the barcode generation unit. The display unit renews and displays a barcode generated by the barcode generation unit.SELECTED DRAWING: Figure 2 |
