  • Publication number: 20200393824
    Abstract: When the learning process is performed and the learning result is set in the wireless slave device, the time required for installing the wireless slave device is increased. Further, when data including the state of the inspection target object detected by the wireless slave device is transmitted as it is, the data size is increased, and the power consumption of the wireless slave device is also increased. A wireless slave device transmits a state of an inspection target object to a setting device as learning data, obtains, as an analysis result, a degree of difference between the state of the inspection target object and the normal state of the inspection target object based on a learning result set by the setting device, and wirelessly transmits data including the analysis result to the wireless master device.
