Remote Operation Rights for Component Mounting Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting systems lack a specific operation method for seamless integration of on-site and remote operations, leading to inefficiencies when field workers and remote workers interact with processing devices in component mounting lines.
Innovation Solution
A component mounting system and method that includes a remote operation control unit, an operation right setting unit, and an error type determination unit, allowing for remote operation of processing devices via a network and adjusting operation rights based on error types, enabling appropriate on-site and remote operations by distinguishing between remote response errors and on-site response errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote operation is allowed for all processing devices, then remote workers can operate devices from distant locations, but on-site workers cannot perform necessary on-site operations
Solution Approach 1:
The operation right setting unit dynamically changes the operation mode between remote and on-site based on the type of error detected. When a remote response error is detected, remote operation rights are granted; when an on-site response error is detected, on-site operation rights are granted. This dynamic adaptation resolves the contradiction by making the system flexible rather than fixed in one operation mode.
Solution Approach 2:
The system changes the parameter of operation rights (remote vs. on-site) based on the error type parameter. The error type determination unit identifies the error category, and the operation right setting unit adjusts the operation mode parameter accordingly, allowing the system to adapt between remote and on-site operations based on operational conditions.
2Ease of operation
If on-site operation is performed for all errors, then field workers can directly address device issues, but remote workers cannot perform remote diagnostics and operations
Solution Approach 1:
The error type determination unit provides feedback about the error category to the operation right setting unit, which then adjusts the operation mode. This feedback loop enables the system to automatically determine whether remote or on-site operation is appropriate, resolving the contradiction by using information feedback to dynamically allocate operation rights between remote and on-site workers.
Solution Approach 2:
The system dynamically switches between on-site and remote operation modes based on real-time error conditions. Rather than being statically configured for one mode, the operation rights are dynamically adjusted according to the detected error type, enabling both remote automation and on-site intervention as needed.
3Productivity
If remote operation rights are granted without error type differentiation, then remote workers can operate devices, but inappropriate operations may occur for errors requiring on-site intervention
Solution Approach 1:
The error type determination unit performs preliminary classification of errors before granting operation rights. By pre-categorizing errors as either remote response errors or on-site response errors, the system ensures that the correct operation mode is selected in advance, preventing inappropriate remote operations and ensuring reliable error handling.
Solution Approach 2:
The system changes the operation rights parameter based on the error type parameter. When the error type is classified as a remote response error, remote operation rights are granted; when classified as an on-site response error, on-site rights are granted. This parameter-based control ensures high productivity for remote operations while maintaining reliability through accurate error-specific differentiation.

AI summary
A component mounting system includes a component mounting line in which a plurality of processing devices are connected to constitute the component mounting line and a management device (management computer) connected to the component mounting line by a network, and each of the plurality of processing devices can be remotely operated via the network by an input unit of the management device. In this component mounting system, it is determined whether or not an error occurring in the processing device is a remote response error (ST1) and a remote operation right enabling the remote operation is set (ST21) with respect to the management device based on a result of the error type determination in a case where the type of the error is the remote response error (Yes in ST1).
