Mobile Terminal Capture Signal for Emergency Evidence Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In emergency situations, users of mobile communication terminals face challenges in capturing and preserving evidence of crimes committed by individuals using nearby terminals, as existing systems lack the capability to identify and record information from other terminals within a specific distance.
Innovation Solution
A mobile communication system and method that involves a first mobile terminal transmitting a capture signal with location and identification information to a base station, which then uses GPS signals to gather and store location and identification data from nearby second mobile terminals, allowing for the identification of criminals based on their terminal information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile communication terminals are used for general communication, then communication convenience is improved, but the ability to capture and preserve crime evidence is insufficient
Solution Approach 1:
The system performs preliminary actions by pre-configuring the capability to capture information from nearby terminals and pre-establishing the protocol for receiving capture signals. When a crime occurs, the victim's terminal can immediately initiate information capture from nearby terminals without requiring real-time manual intervention, thus preserving evidence while maintaining communication convenience.
Solution Approach 2:
The base station serves as an intermediary between mobile terminals. It receives capture signals from victims, coordinates the information capture process, and aggregates data from multiple terminals. This intermediary mechanism enables evidence preservation without requiring direct terminal-to-terminal communication, maintaining the simplicity of regular communication operations.
2Reliability
If information capture capability is added to mobile terminals, then crime evidence preservation is improved, but device complexity increases
Solution Approach 1:
The base station acts as an intermediary that handles the complex information capture coordination. Terminals only need to receive simple capture signals and transmit their own information, while the base station manages the complex processes of identifying nearby terminals, collecting data, and verifying evidence. This significantly reduces terminal device complexity.
Solution Approach 2:
The base station performs multiple functions: it serves as a communication hub, a capture signal receiver, a data coordination center, and an evidence verification system. By consolidating these functions in the base station rather than distributing them across terminals, the system improves evidence preservation capability without increasing terminal complexity.
3Measurement precision
If GPS signals are used to locate terminals, then position accuracy is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous GPS operation, the system uses periodic GPS activation. Terminals only activate GPS to obtain location information when receiving capture signals during crime events. This periodic usage maintains high position accuracy for evidence preservation while significantly reducing overall energy consumption compared to continuous operation.
Solution Approach 2:
The system performs preliminary location determination by having terminals obtain their position data in advance or upon receipt of capture signals. This preliminary action ensures accurate positioning is ready when needed for evidence preservation, while avoiding unnecessary continuous GPS operation that would waste energy during normal communication periods.
