Display Processing Device for Maritime Voice Wireless Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice wireless communication systems face interference issues when exclusive channels are already in use by other ships or land stations, leading to difficulties in maintaining normal communication and requiring additional time and effort to re-determine suitable channels.
Innovation Solution
A display processing device equipped with a receiver, analysis processor, and display processor that displays the time-series change in channel status and determines whether the radio wave source is from a ship or land station, allowing users to select a suitable exclusive channel and prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an exclusive channel is determined for voice wireless communications, then communication efficiency is improved, but interference occurs when the channel is already in use by others
Solution Approach 1:
The system performs preliminary channel status detection before establishing voice wireless communications. The display processing device shows the current usage status of each channel, allowing users to check whether a channel is already in use by other ships or land stations before selecting it for exclusive communication, thereby preventing interference in advance
Solution Approach 2:
The system provides real-time feedback on channel usage status through visual display. The display processor presents information about which channels are currently occupied and which are available, enabling users to make informed decisions about channel selection and avoid selecting channels that would cause interference
2Loss of time
If channel status is not monitored, then device complexity is reduced, but time is lost when re-determining exclusive channels due to interference
Solution Approach 1:
The display processing device automatically monitors and displays channel usage status without requiring manual intervention or complex processing. The system self-updates the channel status information based on detected radio waves, providing real-time information to users who can then independently make channel selection decisions
Solution Approach 2:
The display processing device acts as an intermediary between the radio wave detection system and the user. It receives raw detection data, processes it into meaningful channel status information, and presents it in an easily interpretable format, simplifying the overall system architecture while providing comprehensive channel monitoring capabilities

AI summary
A display processing device capable of preventing generation of interference when performing voice wireless communications between a plurality of ships, or between a ship and a land station, and making normal voice wireless communications start smoothly, is provided. The display processing device includes a receiver and processing circuitry. The receiver receives a radio wave for voice. The processing circuitry performs a determination of a channel used for propagation of the radio wave for voice and a ship/land determination for determining whether an output source of the radio wave for voice is either one of a ship and a land station. The processing circuitry displays, on a screen indicative of a time-series change in the status of use for every channel that may be used, a result of the ship/land determination for the used channel.
