Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video monitoring systems, pan-tilt-zoom devices are often manually configured, leading to increased workload and error probability for maintenance personnel, as existing technologies lack automatic sensing capabilities to differentiate between camera and pan-tilt-zoom device faults, resulting in poor maintenance real-time performance.
Innovation Solution
A pan-tilt-zoom device identification method that sends a keep-alive command with capability information when connecting to a predetermined interface, allowing the camera and management platform to determine the control function and report availability, reducing errors and improving maintenance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration method is used for pan-tilt-zoom device, then maintenance personnel can configure the device, but workload increases and error probability increases
Solution Approach 1:
The pan-tilt-zoom device automatically performs identification and capability reporting functions. When a device connects to the predetermined interface, the pan-tilt-zoom device autonomously sends keep-alive commands with capability information and automatically reports control capability information to the management platform, eliminating the need for manual configuration by maintenance personnel.
Solution Approach 2:
The system implements automatic feedback mechanisms where the pan-tilt-zoom device continuously sends keep-alive commands with capability information to the management platform. The management platform receives and processes this information automatically, enabling real-time status reporting and configuration verification without manual intervention.
2Reliability
If manual troubleshooting is used for device abnormalities, then fault detection can be performed, but maintenance real-time performance deteriorates
Solution Approach 1:
The pan-tilt-zoom device automatically sends keep-alive commands with capability information at regular intervals. The management platform continuously receives and monitors this feedback information, enabling real-time detection of device status changes, connection issues, or capability anomalies without requiring manual troubleshooting.
Solution Approach 2:
The patent replaces manual mechanical troubleshooting processes with automated electronic monitoring and communication systems. The keep-alive command mechanism and automatic capability reporting replace the need for maintenance personnel to physically visit and manually test devices, enabling remote real-time fault detection.
3Productivity
If automatic sensing capability is added to differentiate camera and pan-tilt-zoom device faults, then maintenance efficiency improves, but device complexity increases
Solution Approach 1:
The management platform is designed with universal functionality to handle multiple device types (cameras and pan-tilt-zoom devices) through a unified interface. The platform can automatically differentiate between device types and fault conditions based on the capability information received in keep-alive commands, eliminating the need for separate monitoring systems for different device types.
Solution Approach 2:
The patent introduces the management platform as an intermediary between the pan-tilt-zoom device and the monitoring system. The platform receives capability information from devices, processes the data, and performs fault differentiation, shielding the complexity of automatic sensing mechanisms from end users while maintaining high maintenance efficiency.
