Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sensing devices like cameras and radars are deployed to sense target objects, then sensing accuracy and coverage are improved, but deployment costs and system complexity increase
Solution Approach 1:
The patent makes existing wired communication nodes perform dual functions: both data transmission and target object sensing. By analyzing carrier signals already present in the power line communication system, the invention eliminates the need for separate sensing devices, thereby reducing deployment complexity while maintaining sensing capability
Solution Approach 2:
The communication system serves itself by using its own carrier signals for sensing purposes. The nodes in the wired communication system analyze the carrier signals they already transmit and receive to detect target objects, eliminating the need for external dedicated sensing equipment
2Area of stationary object
If conventional sensing devices like cameras and radars are deployed to sense target objects, then sensing coverage is improved, but deployment costs increase
Solution Approach 1:
Existing wired communication infrastructure is made multi-functional by enabling it to perform both communication and sensing tasks. The carrier signals used for data transmission are simultaneously analyzed for target object detection, leveraging the widespread presence of communication nodes to achieve broad sensing coverage without additional device deployment
Solution Approach 2:
The patent merges the sensing function with the existing communication infrastructure. By combining communication and sensing into a single system using the same hardware nodes and carrier signals, the invention achieves extensive coverage while avoiding the costs associated with deploying separate sensing devices
3Measurement precision
If carrier signals are analyzed in real-time to sense target objects, then sensing accuracy is improved, but calculation overhead and processing time increase
Solution Approach 1:
The patent performs preliminary analysis of carrier signal characteristics and stores them for later comparison. By pre-processing and caching signal features, the system reduces the computational burden during actual sensing operations, maintaining detection accuracy while improving sensing efficiency
Solution Approach 2:
The system uses historical sensing results and carrier signal patterns as feedback to improve future detections. By comparing current carrier signals with stored historical data, the system achieves accurate target object detection without requiring intensive real-time computation for every sensing operation

AI summary
This application provides a target object sensing method and a related device, and is applied to the communication field. The target object sensing method is performed by a first electronic device, and is applied to a wired communication system, where the system includes at least two nodes in a first environment, and the nodes are connected through a wired link. The method includes: obtaining first information, where the first information is information associated with a first carrier signal, and the first carrier signal is a carrier signal loaded by a first node in the at least two nodes to the wired link; determining second information that matches the first information and that is in historical information associated with the first environment, where the second information is information associated with a historically obtained second carrier signal, and information about a target object in the first environment is a known state when the second carrier signal is transmitted in the first environment; and determining, based on the known state corresponding to the second information, information about the target object in the first environment when the first carrier signal is transmitted in the first environment. This greatly reduces costs of deploying cables and devices.
