Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control systems for semiconductor automation equipment face limitations, such as the inability to support USB/PS2 ports, which restricts mouse control and require separate IP allocation for communication, and are incompatible with different operating systems.
Innovation Solution
A real-time remote control system that uses a remote control converter and serial splitter to transmit mouse signals via serial ports, converting them into touch panel data, and employs a network transmission processing unit for IP sharing, allowing communication between semiconductor automation equipment computers without separate IP allocation and supporting diverse operating systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional remote control system uses USB/PS2 port transmission, then mouse control is supported, but the system cannot be applied to semiconductor automation equipment that does not support these ports
Solution Approach 1:
The patent introduces a serial splitter as an intermediary device that converts mouse signals into touch panel signals. The serial splitter receives mouse signals from the remote control system and transforms them into touch panel data that can be processed by the semiconductor automation equipment's front computer, enabling mouse control without direct USB/PS2 port support.
Solution Approach 2:
The patent changes the signal parameter type by converting mouse signals (typically USB/PS2 protocol) into touch panel signals (serial communication protocol). This parameter transformation allows the same control function to work across different communication interfaces, making the system compatible with equipment that only supports serial ports.
2Reliability
If an existing router automatically assigns public IP addresses, then communication is established, but a fixed IP cannot be used and communication with the high order communication unit becomes impossible
Solution Approach 1:
The patent performs preliminary IP address configuration by setting a fixed IP address for the remote control system before communication begins. The network transmission processing unit is pre-configured with a predetermined IP address, eliminating the need for automatic IP assignment during operation and ensuring stable communication with the high order communication unit.
Solution Approach 2:
The patent makes the IP address configuration universal by implementing a fixed IP address scheme that works consistently across different communication scenarios. The network transmission processing unit can handle both data transmission and control signals using the same predetermined IP address, simplifying the communication architecture.
3Adaptability or versatility
If remote control software is installed on both remote and local computers, then remote control functionality is achieved, but connection is impossible when operating systems of the two computers are not the same
Solution Approach 1:
The patent replaces the software-based remote control mechanism with a hardware-based signal conversion mechanism. Instead of relying on operating system-compatible software installations, the system uses a serial splitter and network transmission processing unit that convert and transmit control signals at the hardware level, bypassing operating system dependencies entirely.

AI summary
Disclosed is a real-time remote control system for semiconductor automation equipment which may monitor an operating condition of the semiconductor automation equipment in real-time and enable an Internet protocol (IP) to be shared, so that a plurality of semiconductor automation equipment computers are reliably connected. By transmitting a mouse signal of a remote computer via a serial port of the semiconductor automation equipment computer, even semiconductor automation equipment that does not support USB/PS2 ports can transmit a remote control signal through a mouse of the remote computer, and transmit a signal for monitoring or controlling an operation of the semiconductor automation equipment without a separate IP allocation operation in real-time.
