AI Technical Summary

Technical Problem

In existing technologies, wireless communication between the conveyor trolley and the loading port is easily interfered with, resulting in prolonged dwell time and affecting conveying efficiency.

Method used

By setting a measuring unit on the conveyor trolley to measure the received signal strength of background noise, and controlling the start and stop of interlocking communication by the control unit, it is ensured that interlocking communication is carried out in a low interference environment and that stable communication is stopped in a high interference environment. The storage unit stores suitable radio wave transmission strength for communication.

Benefits of technology

It effectively shortens the dwell time of the conveyor trolley at the handover position, improves conveying efficiency, reduces interference with other communication devices, and enhances the overall communication quality.

Abstract

This invention relates to a wireless communication system and a wireless communication control method. The conveyor trolley (10) includes: a communication unit (11) which performs interlocking communication for the handover of items between the conveyor trolley (10) and the communication device (22) via wireless communication; a measuring unit (12) which uses the communication unit (11) to measure the received signal strength of background noise when the conveyor trolley (10) moves upstream of the handover position relative to the loading port (20); and a control unit (15) which controls the interlocking communication performed by the communication unit (11). The control unit (15) determines whether the received signal strength measured by the measuring unit (12) is less than a reference value. (a) If the received signal strength is determined to be less than the reference value, control is performed to start the interlocking communication when the conveyor trolley (10) moves upstream of the handover position. (b) If the received signal strength is determined to be not less than the reference value, control is performed to start the interlocking communication when the conveyor trolley (10) stops at the handover position.
