Remote Operation System Using Relay Server for Secure Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation systems for electronic appliances, such as measuring instruments, require cumbersome IP address specification and email-based notification, leading to security risks and increased manufacturing costs due to unnecessary features like email transmission and IP address notification functions.
Innovation Solution
A remote operation system that enables remote operation of electronic appliances via the Internet using a relay server and a mobile router, establishing encrypted communication paths without the need for fixed IP addresses or email notifications, allowing secure and cost-effective operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If e-mail transmission function and IP address notifying function are added to the measuring instrument, then the operator can access the measuring instrument without specifying IP address in advance, but the manufacturing cost increases
Solution Approach 1:
The invention introduces a server as an intermediary between the measuring instrument and the operation terminal. The server stores the IP address of the measuring instrument and provides it to the operation terminal through a URL, eliminating the need for the measuring instrument to have e-mail transmission functionality. This resolves the contradiction by achieving easy access without adding complex communication functions to the measuring instrument itself.
2Ease of operation
If e-mail transmission function is added to the measuring instrument, then the IP address can be automatically notified, but security risks increase due to potential unauthorized access
Solution Approach 1:
The server acts as a secure intermediary that controls access to the measuring instrument's IP address. Instead of the measuring instrument directly sending IP addresses via e-mail (which creates security vulnerabilities), the server authenticates operation terminals and selectively provides IP address information through URLs. This eliminates unauthorized access risks while maintaining automatic notification functionality.
3Ease of operation
If the measuring instrument has IP address notifying function, then the operator can easily access the instrument, but the task of copying and pasting IP address character string remains troublesome
Solution Approach 1:
The invention replaces the manual mechanical process of copying and pasting IP address character strings with an automated electronic system. The server sends a URL containing the IP address information directly to the operation terminal, where it is automatically extracted and used for connection. This eliminates the manual copying and pasting steps, saving time and reducing operational complexity.
4Ease of operation
If e-mail is used for IP address transmission, then the IP address can be delivered to the operator, but the process becomes extremely troublesome in locations where e-mail use is restricted
Solution Approach 1:
The server serves as a universal intermediary that works in all environments, including those where e-mail is restricted. Instead of relying on e-mail transmission (which is blocked in secure locations), the server provides IP address information through web-based URLs that can be accessed from any location. This ensures compatibility with restricted environments while maintaining efficient IP address delivery.

AI summary
A remote operation system enables remote operation by an operation terminal of an electronic appliance, which executes a process according to control data from an external apparatus and outputs response data to the external apparatus, via the Internet. The remote operation system includes a first processor connected to the Internet and a second processor locally connected to the electronic appliance and set up for access by the first processor via the Internet. The second processor executes a first process that establishes a first path for reception of transmission data via the Internet from the first processor at any time. The first processor executes a second process that instructs the second processor via the first path to establish a second path for end-to-end communication to enable remote operation of the electronic appliance by the operation terminal via the Internet.
