Abstract: According to one embodiment, a conveyor diagnostic device diagnoses an abnormal state of a cyclically moving conveyor. The conveyor diagnostic device includes a first tilt sensor, a second tilt sensor, a table, and a processing unit. The first and second tilt sensors are attached to a predetermined position of the conveyor and detect tilt angles of the conveyor in a vertical direction and horizontal direction, respectively. The table indicates a relationship between a tilt angle which changes in the vertical direction and sections included in one revolution of the conveyor. The processing unit specifies an abnormality occurrence position of the conveyor based on a tilt angle in the vertical direction, the table, and an elapsed time after ingression for a section corresponding to the tilt angle in the vertical direction, when a tilt angle in the horizontal direction exceeds a predetermined management limit value.

Abstract: Embodiments relate to a data-collection apparatus and a data-collection system using the same. The data-collection apparatus includes a battery, a wireless unit to communicate wirelessly to an external device, a measurement unit to measure a measurement target, a power-supply circuit unit to control power supply to the wireless unit and the measurement unit, and a controller. In response to a data-collection start command from the external device, the controller performs a control such that the power-supply circuit unit supplies power to the measurement unit and wireless unit, and that the data measured by the measurement unit is transmitted via the wireless unit to the external device. In response to a power-saving command from the external device, the controller performs a control such that the power-supply circuit unit stops supplying power to the measurement unit and wireless unit for a predetermined period.

Abstract: According to one embodiment, a system includes a first operation sound collector, a second operation sound collector, a database, a receiver, and controller. The first operation sound collector is provided in a movable part of equipment, and transmits first data including inclination angle data and first operation sound data. The second operation sound collector is provided in a fixed part of the equipment, and transmits second data including second operation sound data being collected simultaneously with the first operation sound data. The database stores operation sound data in normal operation. The receiver simultaneously receives the first data and the second data. The controller determines whether an operation sound is abnormal based on the first data, the second data, and the operation sound data of the database.
