AI Technical Summary

Technical Problem

Existing systems for remotely managing pneumatic fenders face challenges in maintaining stable wireless communication due to radio wave interference from chain nets and the need to position receivers appropriately, while also adhering to legal restrictions on wireless communication.

Method used

A system comprising a sensor, transmitting/receiving terminal, battery, and storage container housed inside the fender, with an omnidirectional antenna and relay device outside, utilizing LPWA communication standards to transmit detection data through gaps in chain nets and adjust communication routes based on signal strength.

Benefits of technology

Enables stable and reliable remote monitoring of fender status without strict legal restrictions, reducing energy consumption and interference, and allowing flexible communication networks.

Abstract

To provide a management system and method that can reliably grasp the status of a pneumatic fender remotely while avoiding strict restrictions on wireless communication.SOLUTION: A sensor 2, a transmitting / receiving terminal 9, and a battery 10 are housed in a storage container 3 and installed inside a pneumatic fender 15 in a landscape-oriented state. The storage container 3 is attached to a mouth fitting 16a and extends in the cylinder axial direction of the pneumatic fender 15. The transmitting / receiving terminal 9 is designed to have an omnidirectional antenna 9b extending in the cylinder axial direction. Wireless communication based on a predetermined LPWA communication standard is performed between the transmitting / receiving terminal 9 and a relay device 11A. Detection data by the sensor 2 is transmitted from the transmitting / receiving terminal 9 to the relay device 11A by the omnidirectional antenna 9b and then transmitted via the relay device 11A to a communication network. Management indexes based on the detection data are displayed on a specific terminal device 12 connected to a communication network 13.SELECTED DRAWING: Figure 1
