Document Type and Number:
Japanese Patent JP6709982
Kind Code:
B2
Abstract:
An object would be to propose a communication system capable of establishing synchronous communication between upper system slaves even when the upper system slaves fail in receiving a beacon signal from an upper system master. The communication system (10) includes a plurality of upper system slaves (2) and an upper system master (1). The upper system master (1) sends a first beacon signal to the plurality of upper system slaves (2) to thereby establish synchronous communication with the plurality of upper system slaves (2). The plurality of upper system slaves (2) include a plurality of lower system slaves (4) and a lower system master (3). The lower system master (3) sends a second beacon signal (B2) to the plurality of lower system slaves (4) when at least any one of the plurality of upper system slaves (2) is in a receiving incapable state of being incapable of receiving the first beacon signal.
