Solution Overview
Problem
Current data communication systems face challenges in efficiently managing data conveyance and communication between multiple Low Voltage Drive Circuits (LVDCs) over a common bus, particularly in allocating channels effectively to support various communication modes such as one-to-one, one-to-many, and broadcast communications, which affects data rate and power consumption.
Innovation Solution
The implementation of Low Voltage Drive Circuits (LVDCs) that utilize a frequency band with multiple channels to transmit and receive data, allowing for efficient channel allocation and utilization through methods like channel allocation tables and dynamic channel allocation based on communication needs, enabling low-power, high-data-rate communications across multiple lines of a bus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple LVDCs share a common bus for data communication, then device complexity is reduced, but channel allocation and data rate efficiency deteriorate
Solution Approach 1:
The common bus is segmented into multiple frequency channels, allowing simultaneous data transmission between multiple LVDC pairs without interference. Each channel operates independently at a specific frequency, enabling parallel communication while maintaining system simplicity.
Solution Approach 2:
The system dynamically allocates frequency channels to LVDC pairs based on real-time communication needs. The channel allocation is not static but adapts to changing data traffic patterns, optimizing data rate efficiency while devices share the common bus.
2Productivity
If frequency-based channel allocation is implemented, then data rate increases, but system complexity increases
Solution Approach 1:
LVDCs autonomously select and allocate frequency channels from the available spectrum based on their communication requirements. The system self-organizes channel assignments without requiring complex centralized control, reducing overall system complexity while maintaining high data rates.
Solution Approach 2:
The system changes the operating frequency parameter dynamically to create multiple communication channels. By varying the frequency parameter across different LVDC pairs, high data rates are achieved while the complexity is managed through parameter diversity rather than structural complexity.
3Use of energy by moving object
If low voltage operation is used, then power consumption decreases, but noise immunity deteriorates
Solution Approach 1:
The system transitions from spatial/voltage-based signal differentiation to frequency-based signal differentiation. By moving to the frequency domain, low-voltage signals can be transmitted with sufficient noise immunity, as frequency separation provides inherent isolation between communication channels.
Solution Approach 2:
The system changes from relying on voltage amplitude for signal integrity to relying on frequency separation. This parameter change allows low-voltage operation to maintain noise immunity by encoding information in frequency rather than voltage level, reducing susceptibility to noise.
