Problem

In non-network positioning systems, nodes cannot communicate with each other, making it difficult to automatically diagnose a failed node, relying on inefficient artificial maintenance for node state diagnosis.

Innovation Solution

A node state detection method and device that acquires and compares signal data from nodes with standard signal feature information, determining the running state of a target node based on visible node signal feature information and node path binding information, enabling automatic diagnosis of node failures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If nodes in non-network positioning system cannot communicate with each other, then system deployment is simple and extensible, but automatic diagnosis of node failures becomes impossible

Engineering Contradiction:
Improvesystem deploymentVSAvoidnode failure diagnosis
Core Design Contradiction:
Ease of manufactureVSExtent of automation

Solution Approach 1:

The patent introduces a server as an intermediary that collects signal data from multiple data acquisition terminals. The server performs the node state detection by comparing received signal data with standard signal feature information, enabling automatic diagnosis without requiring direct communication between nodes. This mediator approach resolves the contradiction by allowing centralized automation while preserving the decentralized node architecture.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback by having data acquisition terminals continuously receive signal data from nodes and send it to the server. The server compares this feedback data with standard signal features and determines node running states, creating a closed-loop monitoring system that enables automatic diagnosis without changing the node communication architecture.

Inventive Principle:
Principle #23Feedback

2Device complexity

If artificial maintenance is used for node state diagnosis, then system architecture remains simple, but diagnosis efficiency and timeliness deteriorate

Engineering Contradiction:
Improvesystem architectureVSAvoiddiagnosis efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system enables self-service by implementing automatic node state detection through the server that continuously monitors signal data from all nodes. The server autonomously compares received signals with standard features and identifies failed nodes without human intervention, dramatically improving diagnosis efficiency while adding only moderate system complexity through the detection module.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical artificial maintenance process with an automated electronic detection system. The server uses signal data processing and comparison algorithms to substitute human diagnostic activities, improving productivity while maintaining relatively simple system architecture through standardized detection procedures.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If manual node diagnosis is performed, then system operation is simple, but timeliness and operability of failure detection worsen

Engineering Contradiction:
Improvesystem operationVSAvoidfailure detection time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system implements continuous monitoring by having data acquisition terminals constantly receive signal data from nodes and transmit it to the server. The server continuously performs comparison operations with standard signal features, ensuring real-time detection of node failures without interrupting system operation, thus reducing detection time while maintaining operational simplicity.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system performs preliminary action by pre-establishing standard signal feature information for each node before operation begins. When signal data is received, the server can immediately compare it against these pre-prepared standards, enabling rapid failure detection without requiring complex real-time analysis, thereby reducing detection time while keeping the system easy to operate.

Inventive Principle:
Principle #10Preliminary action
