Optical Safety System Area Designation Editing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional optical safety systems require cumbersome editing operations to verify if intruder sensing is appropriately performed within designated protection areas, as they necessitate updating safety scanner settings with area designation information.
Innovation Solution
The optical safety system includes a safety scanner with an area designation information receiving section and a setting support device that generates pseudo determination information based on area designation and distance measurement data, allowing for on-screen verification without transmitting updated settings to the scanner, using an edit screen display section and pseudo determination information generation section.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If area designation information is updated in the safety scanner to verify intruder sensing, then sensing accuracy can be checked, but the editing operation becomes troublesome and complex
Solution Approach 1:
The setting support device creates a copy of the area designation information and stores it locally. This copied data can be used for verification purposes without requiring updates to the safety scanner's settings, thereby simplifying the editing operation while maintaining sensing accuracy verification capability
Solution Approach 2:
The setting support device acts as an intermediary between the user and the safety scanner. It handles the verification process using stored area designation information, eliminating the need for users to directly update the safety scanner settings and thus reducing operational complexity
2Manufacturing precision
If area designation information is transmitted to the safety scanner for setting updates, then the protection area can be properly designated, but the setup process becomes time-consuming
Solution Approach 1:
The setting support device performs preliminary actions by storing area designation information locally before it would need to be transmitted to the safety scanner. This allows for quick verification and setup operations without repeated transmission cycles, reducing setup time while maintaining designation accuracy
Solution Approach 2:
By creating and storing a copy of the area designation information in the setting support device, the system eliminates the need for repeated transmissions to the safety scanner during setup and verification, significantly reducing the time required for protection area designation

AI summary
Provided is an optical safety system that enables simplification of an editing operation for area designation information. A safety scanner includes an intrusion sensing section that determines the presence or absence of an intruder into a protection area. The setting support device includes a pseudo determination information generation section that determines a presence or absence of an intruder into a protection area on the basis of an area designation information before being transmitted to the safety scanner and a distance measurement information received from the safety scanner and generates a pseudo determination information indicating the determination result.
