Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trunked radio systems face inefficiencies in acquiring location information from multiple radios simultaneously, leading to channel occupation delays and data collisions, especially when using GPS data queries, as they require sequential channel changes and are not optimized for simultaneous data transmission.
Innovation Solution
An accelerated location information acquiring system that uses a main communication unit with a wireless communication unit capable of broadcasting queries to multiple subscriber radios simultaneously, a global location data organization unit that manages channel allocation and data transmission, and a repeater to extend communication range, allowing for efficient channel use and simultaneous location data acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS data queries are sent to multiple radios sequentially through channel changes, then location information can be acquired from each radio, but channel occupation duration increases and system productivity decreases
Solution Approach 1:
The system segments the location data acquisition process by assigning dedicated time slots to different radios within a multi-slot frame structure. Each radio transmits its GPS data in its assigned slot, allowing parallel acquisition without channel conflicts. This segmentation eliminates the need for sequential channel changes while maintaining accurate location data collection from multiple radios simultaneously.
2Productivity
If radios transmit GPS data actively or passively on the same channel, then location information can be collected, but data collisions occur and reliability decreases
Solution Approach 1:
The system implements periodic action by organizing GPS data transmission into regular time slots within a frame structure. Each radio is assigned specific slots for transmission, creating a periodic pattern that prevents data collisions. The main communication unit collects data from multiple radios in an organized sequence, ensuring reliable acquisition without conflicts while maintaining high transmission efficiency.
3Measurement precision
If channel changes are performed for each GPS data query, then individual radio location data can be obtained, but device complexity and operation difficulty increase
Solution Approach 1:
The system merges multiple GPS data collection operations into a single unified frame structure that accommodates multiple radios simultaneously. Instead of performing separate channel changes for each radio, the main communication unit handles multiple radios within one frame using time-division multiplexing. This merging approach maintains accurate location data collection while significantly reducing channel management complexity and operational difficulty.
