Movable Object Proximity Warning Using Multi-Device Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing proximity warning systems for large, movable objects in environments like surface mines are inaccurate due to difficulties in determining the orientation and dimensions of these objects, leading to potential collisions.
Innovation Solution
The system employs multiple monitoring devices on each object, with at least one device acting as a main unit and another as an auxiliary unit, or both operating identically, to generate device status datasets that include positional and orientation data, allowing for the calculation of a reserved non-circular volume of space, which is broadcast to other devices for accurate proximity warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single GNSS device is used on each vehicle, then the system is simple to install, but it cannot accurately determine the orientation and dimensions of large movable objects
Solution Approach 1:
The system divides a single monitoring function into multiple segmented monitoring devices distributed at different locations on the vehicle. Each device independently determines position and orientation, and their combined data provides comprehensive spatial information about the entire vehicle, resolving the contradiction between measurement precision and device complexity.
2Measurement precision
If multiple monitoring devices are installed on each object, then orientation and dimensions can be accurately determined, but the system complexity and installation difficulty increase
Solution Approach 1:
Each monitoring device is designed as a universal multi-functional unit that can independently perform position determination, orientation calculation, and data broadcasting. This standardization allows multiple devices to be installed without increasing system complexity, as each unit operates autonomously with identical functionality.
Solution Approach 2:
The system replaces complex mechanical cabling and physical connections with wireless communication technology. Monitoring devices exchange data radio-frequency signals, eliminating the need for physical wiring between devices and significantly simplifying installation while maintaining high measurement precision.
3Reliability
If traditional cabling is used to connect monitoring devices, then data transmission is reliable, but installation becomes complex and time-consuming
Solution Approach 1:
The patent substitutes mechanical cable connections with wireless radio-frequency communication for data transmission between monitoring devices. This eliminates complex cabling while maintaining reliable data exchange through standardized wireless protocols, resolving the contradiction between transmission reliability and installation complexity.

AI summary
Vehicles and other objects in a surface mine are equipped with monitoring devices that communicate by radio in order to detect the risk of collisions. The devices are equipped with GNSS-receivers. At least one of the objects has two devices mounted to it. Each of the two devices determines its position independently, which in turn allows determining not only the position, but also the orientation, of the object.
