Publication number: 20240098005Abstract: A master station (111) and a slave station (121) each communicate an individually set, fixed number of communication frames in a cyclic period. The communication frame contains, as communication information, a sequence number and a period number. The master base station (113) and the slave base station (123) determine, upon communication of each communication frame in a wireless manner, if there is a missing communication frame on a basis of the communication information of a this-time communication frame and the communication information of a last-time communication frame. When there is a missing communication frame, a history management server (300) records communication history information of the last-time communication frame and of the this-time communication frame, as preceding/succeeding history information.Type: ApplicationFiled: November 28, 2023Publication date: March 21, 2024Applicant: Mitsubishi Electric CorporationInventors: Yoshihiro OTSUKA, Teruko FUJII, Takenori SUMI, Takahisa YAMAUCHI
