Solution Overview
Problem
Existing management systems for production plants face challenges in generating real-time management screen images due to the need for faster and wider network bandwidth, which increases operational costs, making it difficult to respond quickly to facility state changes.
Innovation Solution
A screen image generation method and device that classify information acquisition into real-time and regular categories, ensuring real-time management screen images while reducing network speed and bandwidth requirements by prioritizing real-time alerts from controllers and regular data updates from sensors.
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 applies local quality by differentiating the acquisition timing based on information type: critical facility state information (alerts) is acquired in real-time with high priority, while general sensor data is acquired at regular intervals. This selective approach ensures real-time monitoring of important parameters without uniformly increasing network bandwidth requirements for all data types, thus resolving the contradiction between real-time property and operational cost.
2Speed
If the network is made faster and wider to enable real-time updates of the management screen image, then the real-time property is improved, but the operational costs increase
Solution Approach 1:
The patent implements local quality by assigning different acquisition priorities to different information types. Facility state information containing alerts is marked for real-time acquisition, while other sensor data uses regular interval acquisition. This differentiated approach allows the system to achieve real-time monitoring capabilities for critical parameters without requiring the entire network infrastructure to operate at maximum speed and bandwidth, thereby reducing operational costs.
3Use of energy by stationary object
If information acquisition is performed at regular intervals to reduce network bandwidth requirements, then operational costs are reduced, but the real-time property of the management screen image deteriorates
Solution Approach 1:
The patent resolves this contradiction by applying local quality through selective information acquisition. Instead of using a uniform acquisition strategy, the system identifies facility state information containing alerts as requiring real-time acquisition, while other information types use regular interval acquisition. This targeted approach ensures that the real-time property is maintained for critical monitoring data without incurring the full operational cost of real-time acquisition for all data types.
4Reliability
If all information from sensors and controllers is acquired in real-time, then the real-time property of the management screen image is improved, but the network bandwidth and speed requirements increase significantly
Solution Approach 1:
The patent applies local quality by differentiating between information types that require real-time acquisition and those that do not. Facility state information, particularly alerts indicating abnormal conditions, is prioritized for real-time acquisition. Other sensor data is acquired at regular intervals. This selective approach reduces the total quantity of data requiring real-time transmission, thereby lowering network bandwidth requirements while maintaining real-time monitoring for critical parameters.
