Title:
MEASUREMENT RECORDING DEVICE FOR MEASURING WORKING TIME WITH PHYSICAL QUANTITY SENSOR SIGNAL
Document Type and Number:
Japanese Patent JP2021067658
Kind Code:
A
Abstract:
To provide a measurement recording device with which it is possible to measure, by connection with only a physical quantity sensor, the working time of a motive power acting upon the physical quantity sensor.SOLUTION: Measurement means 10 of a measurement recording device 1 performs measurement on the basis of an electric signal from a physical quantity sensor 21 that measures a physical quantity changing by operation of a motive power device 22 of a facility 2 and stores measured data in recording means 11. A working time measurement means 12 measures the duration of time from the start to the termination of an electric signal obtained by the measurement means 10 and stores it in working time recording means 14. When the zero state of the electric signal continues for a determination time set by parameter setting means 13 continues, it is determined that measurement is terminated. This determination time is subtracted from the obtained working time to calculate a formal working time. The measurement data and working time data are recorded as a fixed period data for a sum total, an annual report, a monthly report, a weekly report, a daily report and an hourly report.SELECTED DRAWING: Figure 1
