Abstract: A radio communication system includes: slave devices which repetitively transmit, a plurality of times, a radio signal with a prescribed frequency that includes device identification information during a radio communication with a master device; a master device which generates communication situation information including a reception success rate and received signal strength of a radio signal during each radio communication from each slave device; and a failure factor estimation apparatus which, based on communication situation information with respect to a plurality of radio communications including a radio communication in which a communication failure of the received signal strength is lower than prescribed strength and/or the reception success rate is lower than a prescribed rate has occurred, generates and outputs failure factor presentation information indicating a failure inducer estimated to have induced the communication failure and an estimation result of a position of the failure inducer.

Abstract: The disclosure provides a photoelectric sensor that provides useful information to set measurement conditions. The photoelectric sensor includes a light emitting unit having a light emitting element configured to emit detection light toward a detection area, a light receiving unit having a light receiving element configured to receive the detection light from the detection area and to obtain a detection value corresponding to the amount of light received, and a display unit configured to display information about the detection value in the light receiving unit. When the detection value varies across a predetermined threshold, the display unit displays a transit time that is the time from when the detection value crosses the predetermined threshold until when it crosses the predetermined threshold again, and a variation amount of the detection value in the variation.

Abstract: A wireless communication device is configured to wirelessly transmit predetermined information possessed by the wireless communication device to a master device corresponding thereto at predetermined transmission intervals, and the wireless transmission is performed in accordance with a predetermined time division multiple access scheme. The wireless communication device: acquires, from a predetermined wireless slave device included in one or more wireless slave devices different from the wireless communication device, unrelated transmission information that is transmission information wirelessly transmitted to a master device, corresponding to the predetermined wireless slave device, in accordance with the predetermined time division multiple access scheme and that includes identification information identifying the predetermined wireless slave device, the unrelated transmission information being acquired at the time of the wireless transmission; on the basis of the identification information included in the unrelated transmission information, the acquisition time of the unrelated transmission information, and information relating to a transmission sequence, determines a predetermined time slot for the wireless communication device to transmit the predetermined information to the master device corresponding thereto in accordance with the predetermined time division multiple access scheme; and transmits the predetermined information. Consequently, provided is wireless communication technology that enables information collection using high-speed and highly reliable wireless communication.
