Multi-Channel Radio with Dynamic Priority Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public safety personnel face challenges in managing communications during critical situations while using two radios to monitor multiple channels, leading to potential missed critical information due to cumbersome operation and divided attention.
Innovation Solution
A radio communication device operating in multi-watch mode that simultaneously receives communications on multiple channels, prioritizes the primary channel by default, but switches to prioritize the non-primary channel when critical information is detected, allowing for timely acknowledgment through a talk-back channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If public safety personnel use two physical radios to monitor more than one channel at a time, then the ability to monitor multiple channels is improved, but the ease of operation deteriorates and critical information may be missed
Solution Approach 1:
The patent combines multiple channel monitoring capabilities into a single radio device. The radio communication device is configured to simultaneously receive and monitor communications on a primary channel and multiple secondary channels, eliminating the need to use two separate physical radios. This merging approach maintains the ability to monitor multiple channels while significantly improving ease of operation by consolidating control and management functions in one device.
2Adaptability or versatility
If public safety personnel use two physical radios to monitor multiple channels, then channel monitoring capability is improved, but the reliability of critical information reception deteriorates due to divided attention
Solution Approach 1:
The patent implements a feedback mechanism that automatically detects when a secondary channel contains critical information and notifies the user. The radio communication device monitors communications on secondary channels and provides feedback alerts when critical information is detected, ensuring that important messages are not missed even when the user is primarily focused on the primary channel. This feedback system significantly improves the reliability of critical information reception.
Solution Approach 2:
The radio communication device performs self-service by automatically analyzing incoming communications on secondary channels to identify critical information. The device autonomously determines whether a communication contains critical information and generates appropriate notifications without requiring constant manual monitoring by the user, thereby improving reliability while reducing operator burden.
3Loss of time
If the radio communication device switches to prioritize non-primary channel when critical information is detected, then the response time to critical information is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamic channel prioritization where the radio communication device can switch between primary and secondary channel priorities based on the content being monitored. When critical information is detected on a secondary channel, the device dynamically adjusts its operation to prioritize that channel, allowing the user to respond immediately. This dynamic behavior is achieved through programmable logic that automatically manages the switching, minimizing the perceived complexity for the user while improving response time.
Data Source
AI summary
A method for operating a radio communication device in a multi-watch mode is provided. The radio communication device receives communications on a primary channel and at least one non-primary channel. Further, a talk-back channel is enabled to respond to communications received on the primary channel. The radio communication device determines whether there is any transmission activity in response to a communication received on the non-primary channel. The radio communication device further determines whether the communication received on the non-primary channel comprises critical information when there is no transmission activity for a pre-defined time period since the communication was received on the non-primary channel. When the radio communication device determines that the communication received on the primary channel comprises critical information, the radio communication device switches to the talk-back channel to respond to communications received on the non-primary channel.
