Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, existing technologies fail to effectively determine the influence range of an emergency situation and immediately establish communication with users within that range, limiting timely assistance in emergency scenarios.
Innovation Solution
A wireless communication system comprising a management device, operator terminal, and communication terminals that receive audio signals and position information to determine emergency situations, specify communication terminals within the influence range, and control communication to establish immediate contact with users through dual wireless communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio signals and position information are received from communication terminals to determine emergency situations, then the ability to identify emergency situations is improved, but the complexity of the management device increases
Solution Approach 1:
The management device is divided into distinct functional units: a reception unit for receiving audio signals and position information, a determination unit for analyzing emergency situations, a decision unit for determining influence ranges, and a specification unit for identifying transmission destinations. This segmentation allows each unit to perform its specific function independently, improving emergency detection reliability while organizing complexity into manageable modules.
2Measurement precision
If the influence range of emergency situations is determined based on positional relationships, then the precision of emergency area identification is improved, but the time required for decision making increases
Solution Approach 1:
The system continuously monitors and maintains position information from multiple communication terminals in advance. When an emergency situation is detected, the decision unit can immediately calculate the influence range using the pre-acquired positional data, avoiding time-consuming data collection during the emergency response phase while maintaining high precision in influence range determination.
3Speed
If control signals are transmitted to communication terminals within the influence range to establish immediate communication, then the speed of emergency response is improved, but the quantity of communication required increases
Solution Approach 1:
The specification unit identifies and targets only the specific communication terminals located within the determined influence range of the emergency situation. Control signals are transmitted selectively to these localized terminals rather than broadcasting to all terminals in the system. This localized approach enables fast emergency response by reaching affected users immediately while minimizing the total quantity of communication signals required.

AI summary
A wireless communication system includes a management device which receives an audio signal and position information from wireless communication terminals by a first wireless communication system, determines whether an emergency situation signal has been received, decides an emergency-situation influence range, specifies a transmission-destination communication terminal for a control signal, and transmits information to an operator terminal and the control signal to the transmission-destination communication terminal by the first wireless communication system, the operator terminal which receives, by the first wireless communication system, the position information and the audio signal and the transmission-destination information, and transmits, by a second wireless communication system, an audio signal of the operator terminal to the wireless communication terminal, and the wireless communication terminal which transmits the audio signal to the management device to generate the control signal and receives the control signal from the management device, and transmits/receives the audio signal to/from the operator terminal.
