Title:
WIRELESS COMMUNICATION SYSTEM, CONVEYANCE CARRIER-SIDE COMMUNICATION DEVICE, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/074291
Kind Code:
A1
Abstract:
A wireless communication system (10) comprises: a conveyance carrier (1); a conveyance carrier-side communication device (11); and a port-side communication device (3) that implements interlock communications with the conveyance carrier-side communication device (11) at a prescribed cycle through wireless communications. The conveyance carrier-side communication device (11) comprises a determination unit (111) and a processing unit (112). Before a pairing signal is transmitted, the determination unit (111) determines whether interlock communications are being implemented by another conveyance carrier (1) using the same channel as a channel scheduled to be used in wireless communications. If the determination unit (111) has determined that the abovementioned interlock communications are being implemented, the processing unit (112) implements control so as to shift the transmission timing of the signal pertaining to interlock communications from the transmission timing of the signal pertaining to interlock communications by the other conveyance carrier (1).
