  • Patent number: 12546806
    Abstract: A stretch detection system of a power transmission mechanism is connectable to a conveyor system including a motor, a rotation mechanism driven by the motor, and the power transmission mechanism driven by rotation of the rotation mechanism. The stretch detection system converts a signal of a current of the motor into a frequency domain signal, and calculates an integral value by performing integration on the frequency domain signal obtained by the frequency domain signal conversion unit, by using, as an integration range, at least one of regions of a sideband wave having a frequency determined using a rotation frequency of the rotation mechanism. A stretch diagnosis unit diagnoses a state of stretch of the power transmission mechanism by using the integral value calculated by the integral value calculation unit. Further, an output unit outputs a diagnosis result of the stretch diagnosis unit.

  • Publication number: 20240179098
    Abstract: When the number of real-time events received from the same device exceeds a threshold value within a predetermined period of time, the monitoring server transmits a data sending request for stopping transmission of real-time events but transmitting regular events to the device. When it is determined, based on the regular events received from the device that has been stopped from transmitting real-time events, that the abnormality in the device has been resolved, a data sending request for restarting to transmit real-time events is transmitted to the device.
