Gas Supply Remote Control with Authority and Operation Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity and size of semiconductor manufacturing processes require more human resources and time to individually control multiple gas supply equipment, leading to inefficiencies in gas supply operations.
Innovation Solution
A method of remotely controlling gas supply equipment using a remote control server to check operation allowance conditions, authority, and perform operations, with a control apparatus, equipment controller, and communication interfaces to manage and display operation status and feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If gas supply equipment is individually controlled manually, then operation reliability can be maintained through direct monitoring, but human resources and time consumption increase significantly
Solution Approach 1:
A remote control server is introduced as an intermediary between operators and gas supply equipment. The server receives control requests, checks operation allowance conditions and remote control authority, then transmits commands to the gas supply equipment. This intermediary system enables centralized remote control of multiple equipment units, reducing manual intervention while maintaining operational reliability through automated monitoring and control protocols.
2Productivity
If remote control is implemented without comprehensive checks, then operation speed increases, but system reliability and security decrease
Solution Approach 1:
The system performs preliminary checks before executing remote control operations. The remote control server checks operation allowance conditions (whether the gas supply equipment can accept remote control) and remote control authority (whether the operator has permission) before transmitting control commands. This preliminary verification ensures system reliability and security while maintaining efficient operation speed by automating the check process.
Solution Approach 2:
The system implements feedback mechanisms where the gas supply equipment transmits operation status and feedback signals back to the remote control server. The server monitors operation completion status and maintains communication throughout the control process, enabling real-time verification and ensuring reliable operation while maintaining efficient remote control.
