摘要： A wireless communication device, a wireless information collection system, and a wireless communication method are provided. The wireless communication device is configured to wirelessly transmit predetermined information provided therein to its master device in a predetermined transmission cycle and executes the wireless transmission in a time slot of itself according to a predetermined time division multiple access scheme together with one or more wireless slave devices including at least a reference wireless slave device. First unrelated transmission information including reference transmission time information wirelessly transmitted from the reference wireless slave device to its master device in the predetermined time division multiple access scheme is acquired during the wireless transmission and a time counted by an internal timer unit is corrected based on an amount of correction calculated from an acquisition time of the first unrelated transmission information and the reference transmission time information included in the first unrelated transmission information.

摘要： A 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, the wireless communication device 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.

摘要： Provide is a radio communication system suitable for use in a factory or the like. The radio communication system includes a receiver provided with a plurality of antennas, and a transmitter for periodically transmitting a radio signal for information transmission including information to be notified to the receiver, and the receiver is an information receiver. Based on the output of each antenna during a period in which the transmission radio signal is not transmitted, a weighting factor for each antenna is generated, and the generated weighting factor is used to process the radio signal for information transmission from the receiver.

摘要： 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.

摘要： 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.
