Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing power communications systems face challenges in meeting the diverse communication requirements of different types of information due to the limitations of dedicated licensed frequency bands, which have limited bandwidth and are not suitable for real-time control information or high-data-throughput metering data.
Innovation Solution
The method involves using multiple frequency bands, including dedicated licensed, non-dedicated licensed, and unlicensed frequency bands, to adapt the frequency band licensing status to the type and emergency degree of the information being transmitted, allowing for flexible meeting of transmission requirements by determining the target frequency band based on the information type and emergency level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a dedicated licensed frequency band is used for power communications, then coverage area is improved, but bandwidth is limited
Solution Approach 1:
The patent combines multiple frequency bands (licensed and unlicensed) into a unified communication system. The base station aggregates resources from both licensed bands (providing coverage) and unlicensed bands (providing bandwidth), merging their advantages to simultaneously achieve wide coverage and high data throughput.
Solution Approach 2:
The communication system is designed to operate across multiple frequency bands with different licensing statuses. The base station performs multi-functionality by managing both licensed band communications (for control and coverage) and unlicensed band communications (for high-speed data), making the system versatile in handling different communication requirements.
2Reliability
If a dedicated licensed frequency band is used for power communications, then transmission reliability is improved, but adaptability to different information types is limited
Solution Approach 1:
The patent segments different types of information (control information, metering data, monitoring data) and assigns them to different frequency bands based on their requirements. Control information with high reliability requirements uses licensed bands, while metering data with high bandwidth requirements uses unlicensed bands, achieving differentiated service through segmentation.
Solution Approach 2:
The system dynamically selects frequency bands based on information type and channel conditions. The base station adaptively allocates licensed and unlicensed band resources according to real-time communication needs, making the system flexible and adaptable to varying information transmission requirements.
3Reliability
If only licensed frequency bands are used, then transmission quality is improved, but system complexity increases due to spectrum management
Solution Approach 1:
The base station acts as an intermediary that manages spectrum allocation between licensed and unlicensed bands. It handles the complexity of spectrum management by making centralized decisions on band selection and resource allocation, shielding terminal devices from complexity while maintaining high transmission quality.
4Quantity of substance
If unlicensed frequency bands are used to increase bandwidth, then data throughput is improved, but transmission reliability deteriorates
Solution Approach 1:
The patent applies different quality characteristics to different frequency bands. Licensed bands provide high reliability for control information, while unlicensed bands provide high bandwidth for metering data. Each band is optimized for its specific function, achieving local quality optimization that resolves the contradiction between throughput and reliability.
