Abstract: In the disclosure, a failure of a device performing work while moving is more reliably detected while the data amount of failure diagnosis data is reduced. The disclosure includes a frequency analyzing part which performs a frequency analysis on acquired data from an acceleration sensor; a maximum frequency detecting part which detects a maximum frequency from a result of the frequency analysis; and a failure diagnosis data generating part which sets a frequency twice or more of the maximum frequency as a sampling frequency, samples the acquired data from the acceleration sensor, and generates the failure diagnosis data.

Abstract: The disclosure is provided to transmit a sensor value from a sensor to an external device with high efficiency. A sensor value of a sensor is acquired, basic data as time-series data is generated with reference to the acquired sensor value, differential data indicating a difference between the basic data and measurement data as time-series data corresponding to the sensor value acquired from the sensor is generated, and the differential data is transmitted to an external device through wireless communication.

Abstract: Provided is a technology that enables a plurality of sensor information to be synchronized for a technology of a sensor management device communicating with a plurality of wireless sensors in a time division manner. A sensor management device includes a transmission unit that transmits acquisition start instructions for starting acquisitions of sensor information to a plurality of wireless sensors respectively at different timings; and an extraction unit that extracts a plurality of common period sensor information that the plurality of wireless sensors have acquired in the common period from the plurality of sensor information with reference to deviation of times at which the transmission unit has transmitted the acquisition start instructions to the plurality of wireless sensors.

Abstract: A tag communication apparatus conducts wireless communication with an RFID tag through a radio wave. The tag communication apparatus includes a data receiver that receives transmit data to be transmitted to the RFID tag, a data compressor that compresses at least a part of the transmit data obtained by the data receiver, and outputs the compressed data, and a transmitter that transmits the compressed data, which is compressed and output by the data compressor, to the RFID tag.
