PTZ Camera Path Selection for Slip Ring Wear Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The long-term and frequent rotation of pan-tilt-zoom cameras leads to damage of slip rings and cables due to friction, resulting in a shortened rotation life and increased hardware costs when trying to improve this life.
Innovation Solution
A method and apparatus that determine and select a rotation path for the pan-tilt-zoom camera based on life load values of preset position points to evenly distribute wear, thereby prolonging the life of the slip ring and cables without increasing hardware costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pan-tilt-zoom camera rotates frequently between preset positions to monitor different scenes, then the monitoring coverage and functionality are improved, but the friction damage to the slip ring and cables increases, shortening the rotation life
Solution Approach 1:
The patent applies dynamics by making the rotation direction adaptive rather than fixed. The control method dynamically selects between clockwise and counterclockwise rotation paths based on real-time wear conditions of the slip ring, allowing the system to adjust its operation to minimize damage accumulation in any single direction
Solution Approach 2:
The patent changes the operational parameters of rotation by introducing wear level as a decision parameter. The control method monitors wear levels of the slip ring and uses this parameter to determine the optimal rotation direction, transforming a simple on/off control into a parameter-based adaptive control system
2Duration of action of moving object
If hardware components with better wear resistance are selected to improve rotation life, then the durability of the slip ring and cables is improved, but the hardware cost increases
Solution Approach 1:
The patent changes the operational parameters to optimize wear distribution. By adjusting the rotation direction based on real-time wear conditions rather than relying on higher-quality materials, the system achieves extended rotation life through intelligent control rather than expensive hardware upgrades
Solution Approach 2:
The patent replaces mechanical improvement (better wear-resistant materials) with a control system approach. Instead of upgrading the physical components to be more durable, the system uses intelligent path selection and wear monitoring to reduce mechanical stress on existing components

AI summary
Provided are a pan-tilt-zoom camera control method and apparatus, a pan-tilt-zoom camera and a storage medium. The method includes following steps. A clockwise path and a counterclockwise path for a pan-tilt-zoom camera to rotate from a current preset position to a target preset position are determined; a current rotation path is selected from the clockwise path and the counterclockwise path according to life load values of at least two first position points that the clockwise path needs to pass and life load values of at least two second position points that the counterclockwise path needs to pass, where a life load value is used for characterizing the total number of times that the pan-tilt-zoom camera passes a preset position point in a pan and tilt; and the pan-tilt-zoom camera is controlled to rotate from the current preset position to the target preset position according to the current rotation path.
