Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automation systems in industrial settings face challenges with restricted accessibility and the need for physical presence in a central control room for accessing and interacting with remote terminal units, limiting convenient access and real-time monitoring of alerts and alarms.
Innovation Solution
A method and system for setting up a remote terminal unit (RTU) for social networking, enabling configuration and registration on a social network platform with participant permissions and task management, allowing remote access and interaction through a social network platform, integrating with SCADA systems for data acquisition and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical access control is implemented in a central control room, then security and controlled access are improved, but accessibility and convenience for remote monitoring are worsened
Solution Approach 1:
The patent introduces a social network platform as an intermediary between the automation system and users. This mediator enables remote access to monitoring data and alert notifications without requiring physical presence in the control room, thus resolving the contradiction between security (maintained through controlled access lists) and accessibility (improved through remote social network access).
Solution Approach 2:
The patent transitions access from a single physical dimension (control room location) to multiple dimensions by enabling access through social network platforms. Users can access the system from any location with internet connectivity, adding a spatial dimension freedom while maintaining security through authenticated access control lists.
2Reliability
If operators must be present in the control room to monitor alerts and alarms, then real-time monitoring is improved, but loss of time for travel and physical presence is worsened
Solution Approach 1:
The social network platform serves as a mediator that delivers alert and alarm notifications directly to participants' devices. This eliminates the need for operators to physically travel to the control room to check for alerts, maintaining real-time monitoring capability while eliminating travel time and physical presence requirements.
Solution Approach 2:
The system creates digital copies of alert and alarm information and transmits them through the social network platform to participants' devices. This copying mechanism allows operators to receive real-time notifications anywhere with internet access, eliminating the need for physical presence in the control room while maintaining monitoring effectiveness.
3Reliability
If centralized control room architecture is used, then system control and supervision are improved, but adaptability for distributed access is worsened
Solution Approach 1:
The patent makes the control system universal by enabling access through multiple channels: traditional control room interfaces and social network platforms. This multi-functionality allows the same centralized control system to serve both centralized and distributed access needs, improving adaptability without sacrificing control capability.
Solution Approach 2:
The system dynamically adapts to different access scenarios by routing notifications and interactions through appropriate channels. The social network platform provides dynamic access for distributed participants while the control room maintains centralized control capabilities, allowing the system to flexibly handle both centralized and distributed operation modes.
