Robot Alarm Segmentation for Enable-State Fault Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot control systems face challenges in efficiently identifying alarms indicating robot abnormalities, as alarms for enable apparatus operation state changes can obscure other abnormality alarms, leading to decreased efficiency in alarm identification.
Innovation Solution
A robot control device with a communication processing unit to obtain operation states from enable apparatuses, an alarm setting unit to differentiate and set alarms for robot abnormalities and enable apparatus operation state changes, and an alarm cancellation unit to cancel alarms based on operation state changes, ensuring only relevant alarms are maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an alarm is set every time the enable apparatus operation state changes, then the robot safety is ensured, but it becomes difficult to identify alarms indicating other robot abnormalities
Solution Approach 1:
The alarm system is segmented into different types: enable apparatus operation state alarms and other robot abnormality alarms. The alarm display is divided into a first display region for enable apparatus alarms and a second display region for other alarms, allowing operators to easily distinguish and identify the specific type of alarm without confusion.
Solution Approach 2:
Different visual qualities are applied to different alarm types through distinct display regions. The first display region specifically displays enable apparatus operation state alarms, while the second display region displays other robot abnormality alarms, providing localized visual characteristics that help operators quickly identify the nature of each alarm.
2Reliability
If multiple alarms are set simultaneously, then comprehensive monitoring is achieved, but the alarm identification task becomes more complex
Solution Approach 1:
The alarm display is segmented into multiple independent regions: a first display region for enable apparatus operation state alarms and a second display region for other robot abnormality alarms. This segmentation allows comprehensive monitoring of all alarm types while maintaining simple identification through spatial separation.
Solution Approach 2:
The alarm system transitions from a single-dimensional alarm list to a two-dimensional display layout with distinct regions. By adding the spatial dimension of display regions, the system can present multiple alarm types simultaneously in an organized manner that reduces identification complexity.

AI summary
A robot control device according to one embodiment of the present disclosure comprises: a communication processing unit for acquiring, from an enable device, an operation state indicating whether operation of a robot is to be permitted; an alarm setting unit for stopping movement of the robot and setting an alarm when an operation state indicating that operation of the robot is not permitted is acquired, or another abnormality of the robot that is not based on the operation state is detected; and an alarm cancelation unit for executing a cancelation process for canceling the relevant alarm only when an operation state indicating that operation of the robot is permitted is acquired in a state in which the alarm has been set and also the alarm that has been set is the alarm based on the aforementioned operation state.
