Plant Management Screen Generation With Tiered Data Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In management systems for production plants, generating a real-time management screen image that indicates the state of facilities is challenging due to the need for faster and wider network bandwidth, which increases operational costs, making it difficult to respond quickly to changes in facility states.
Innovation Solution
A screen image generation method and device that classify data acquisition into real-time alerts from facility controllers and regular data from sensors, allowing for real-time monitoring of critical alerts while reducing the frequency of less critical data acquisition, thereby ensuring real-time updates without the need for excessively fast and wide network bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information is acquired from the facility and sensor at shorter time intervals to update the management screen image in real-time, then the real-time property of the management screen image is improved, but the network speed and bandwidth requirements increase, leading to higher operational costs
Solution Approach 1:
The patent segments data into two categories: alert information from controllers that requires real-time acquisition, and general operational data from sensors that can be acquired at regular intervals. This segmentation allows the system to prioritize critical information while reducing overall data transmission frequency, thereby maintaining real-time monitoring capability for important parameters while lowering network bandwidth requirements and operational costs.
Solution Approach 2:
The patent changes the acquisition parameter (time interval) based on data type: short time intervals for alert information from controllers, and regular longer intervals for sensor data. This parameter adjustment optimizes the balance between real-time monitoring needs and network resource consumption, reducing operational costs while maintaining essential real-time monitoring capabilities.
2Speed
If the network is made faster and wider to reduce operational costs, then the real-time monitoring capability is improved, but the operational costs increase
Solution Approach 1:
The patent segments data transmission requirements by type, transmitting only critical alert information at high speed and frequency, while transmitting general sensor data at lower frequencies. This selective segmentation optimizes network utilization, allowing the system to achieve effective real-time monitoring for critical parameters without requiring continuously high network bandwidth, thereby reducing operational costs.
Solution Approach 2:
The patent dynamically adjusts data acquisition and transmission parameters based on data criticality: alert information from controllers is transmitted with high priority and frequency, while sensor data uses regular intervals. This parameter optimization reduces overall data transmission volume and network resource consumption, lowering operational costs while maintaining essential monitoring speed for critical parameters.
