Existing wired sensor systems face challenges with physical wiring damage, complexity, and inefficiency in real-time data transmission, particularly in harsh environments and when adding new sensors, as they require new wiring and are prone to damage from elements and vibrations.
Innovation Solution
A wireless sensor network system using remote transceivers that periodically report normal operating conditions and delay abnormal readings, with priority levels for communication to ensure timely and reliable data transmission to a base station, employing frequency shift keying, Gaussian Frequency Shift Keying, Frequency Hopping Spread Spectrum, or Direct Sequence Spread Spectrum for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical wiring is used to connect sensors to the logic device, then reliable data transmission can be achieved, but the system complexity increases and the wiring is susceptible to damage from elements and vibrations
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless communication system. Remote transceivers transmit sensor data wirelessly to the base station using radio frequency signals, eliminating the need for physical wiring while maintaining data transmission reliability. This substitution resolves the contradiction by removing the mechanical component that causes complexity and vulnerability.
Solution Approach 2:
The patent introduces remote transceivers as intermediary devices between sensors and the base station. These transceivers receive data from sensors and transmit it wirelessly to the base station, serving as a mediator that eliminates the need for direct physical wiring connections while ensuring reliable data transmission.
2Adaptability or versatility
If new sensors are added to the wired system, then monitoring capability is enhanced, but new wiring must be installed increasing system complexity
Solution Approach 1:
The wireless communication system allows new sensors to be added without any physical wiring installation. Each sensor is paired with a remote transceiver that communicates wirelessly with the base station, enabling easy system expansion while avoiding the complexity of wiring new connections.
Solution Approach 2:
The base station is designed to universally communicate with multiple remote transceivers using the same wireless communication protocol. This universal interface allows different types of sensors to be added to the system without requiring specialized wiring or communication infrastructure, enhancing adaptability while maintaining simplicity.
3Speed
If abnormal sensor readings are reported immediately, then rapid response to critical conditions is achieved, but lower priority communications may be delayed
Solution Approach 1:
The patent implements dynamic priority arbitration in the remote transceivers. When multiple transceivers need to communicate simultaneously, the system dynamically adjusts transmission priorities based on the nature of the data being transmitted. Abnormal readings are automatically assigned higher priority and transmitted immediately, while normal readings use lower priority channels, resolving the time conflict between different communication types.
Solution Approach 2:
Different parts of the communication system are assigned different quality characteristics. The patent creates separate communication channels with different priority levels - high-priority channels for abnormal readings that require immediate transmission, and low-priority channels for normal operational data. This local differentiation of communication quality allows rapid response to critical conditions without significantly impacting normal communications.
