Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT solutions face challenges in navigation and protection systems for moving vehicles, particularly in mountainous terrains where IoT devices lack access to the IoT network and GPS, and there is a need for efficient data collection, processing, and decision-making in smart environments.
Innovation Solution
An object control system that utilizes roadside, lane line, and center barrier stud IoT devices, with a relay or grandmaster IoT device at the top of the mountain to provide access to the IoT network, and employs asynchronous communication links using Ethernet packet protocols, IP packet protocols, and precision time protocols like IEEE1588 for synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If roadside, lane line, and center barrier stud IoT devices are deployed in mountainous terrains, then navigation and protection capabilities are improved, but network connectivity and GPS access deteriorate due to terrain blockage
Solution Approach 1:
The patent introduces intermediary devices (roadside units, relay nodes) that act as mediators between GPS-denied areas and the external network. These intermediaries receive, store, and forward navigation data and vehicle telemetry, enabling continuous operation without direct GPS or network access. The relay nodes create a distributed communication infrastructure that bypasses terrain blockages.
Solution Approach 2:
The system pre-loads navigation routes, map data, and communication protocols into local devices before vehicles enter GPS-denied mountainous regions. Roadside units are pre-configured with route information and can provide guidance without real-time network access. This preliminary preparation ensures navigation continuity when external connectivity is unavailable.
2Measurement precision
If distributed IoT devices collect and process data in real-time, then navigation accuracy and collision prevention are improved, but data transmission latency increases in remote mountainous areas
Solution Approach 1:
The patent divides the navigation and data processing system into segmented, distributed components: onboard vehicle units, roadside units, and relay nodes. Each segment performs localized data processing and decision-making independently. This segmentation enables real-time navigation accuracy at each location while reducing the need for constant long-distance data transmission, thereby mitigating latency issues in remote areas.
3Reliability
If Ethernet packet protocols and precision time protocols are used for synchronization, then network coordination and collision prevention are improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent employs universal communication protocols (Ethernet, IEEE 1588 Precision Time Protocol) that can be implemented across diverse device types (onboard units, roadside units, relay nodes). These protocols provide multi-functional capabilities: Ethernet handles data transmission while IEEE 1588 provides time synchronization, both essential for collision prevention and coordinated navigation. This universality simplifies integration despite the inherent complexity of the protocols themselves.

AI summary
The rise of the connected objects known as the “Internet of Things” (IoT) will rival past technological marvels. This application discloses a novel object control system for navigation of moving vehicles in country roads and freeways. The object control system uses roadside, lane lines, and center barrier stud Internet of Things (IoT) devices to assist the navigation. In mountainous terrains that stud IoT devices have no access to IoT network and GPS a relay or grandmaster IoT device at the top of the mountain is used to provide access to IoT network by stud IoT devices.
