Controller Smart Camera Inspection Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart cameras lack sufficient processing capability for complex image inspection tasks, particularly when handling high loads of inference and learning, necessitating a switch to controller-based operation to enhance processing capacity.
Innovation Solution
A controller system that can cooperate with smart cameras by allowing two operational modes: one where the smart camera performs all image generation and inspection processing, and another where the smart camera generates images and transfers them to the controller for inspection processing, thereby leveraging the controller's higher processing capability when needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smart camera is used to execute image inspection independently, then the installation location flexibility is improved and wiring is simplified, but the processing capability becomes insufficient for complex inspection tasks
Solution Approach 1:
The inspection system is segmented into two operational modes: smart camera-only mode for simple tasks and controller-assisted mode for complex tasks. The controller can be connected via wireless communication, allowing the system to segment processing responsibilities dynamically based on task requirements.
Solution Approach 2:
The smart camera is designed with multi-functionality to operate independently for basic inspection tasks while also being capable of collaborating with an external controller for advanced inspection tasks. This universal design allows the same device to adapt to different operational requirements without requiring separate systems.
2Reliability
If a controller is introduced to enhance processing capability, then the inspection processing capability is improved, but the device complexity increases
Solution Approach 1:
The system dynamically adjusts its complexity by allowing optional connection to a controller. When complex inspection tasks are required, the controller is connected to provide enhanced processing capability. When simple tasks are performed, the system operates without the controller, maintaining low complexity. This dynamic configuration resolves the contradiction between capability and complexity.
3Productivity
If multiple smart cameras are added to cope with increased processing load, then the processing capability is improved, but the system cost increases
Solution Approach 1:
Instead of adding multiple expensive smart cameras, the system introduces a controller as an intermediary device that provides enhanced processing capability. The controller receives inspection tasks from the smart camera, performs complex processing, and returns results. This intermediary approach achieves the desired productivity improvement at lower cost compared to multiplying smart camera units.

AI summary
Provided is a controller capable of cooperating with a smart camera. The controller to which the smart camera is connectable includes a setting unit that receives a setting of one of a first mode in which the smart camera alone executes generation processing of an inspection target image and inspection processing on the inspection target image, and a second mode in which the smart camera executes generation processing of the inspection target image and transfer processing of the inspection target image to the controller, and the controller executes inspection processing on the transferred inspection target image. When the setting of the second mode is received, the inspection unit of the controller executes inspection processing.
