Unit Controller Fallback Control When Display Panel Communication Fails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users cannot operate equipment units when the display panel is damaged or abnormal, as existing systems rely solely on communication with the display panel controller for control operations.
Innovation Solution
The unit controller detects communication with the display panel controller and processes control data independently to perform operations, including delay processes and locking/unlocking instructions, even if communication is lost, allowing for continued operation of the equipment unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system relies solely on communication with the display panel controller for control operations, then the display panel can provide unified control interface, but the equipment unit cannot operate when the display panel is damaged or abnormal
Solution Approach 1:
The patent divides the control function into two independent parts: the display panel controller handles control when communication is normal, while the unit controller handles control when communication is lost. This segmentation allows the system to maintain control capability through different pathways depending on the communication status, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The unit controller pre-stores parsed control data and delay information received from the state controller. When communication with the display panel controller is lost, these pre-stored data enable the unit controller to immediately execute control operations without waiting for new instructions, ensuring continuous operation and resolving the contradiction.
2Reliability
If the unit controller processes control data independently, then the equipment unit can operate with faulty display panel, but the processing load shifts from unit controller to display panel controller
Solution Approach 1:
The patent implements dynamic control architecture where the display panel controller and unit controller can switch roles based on communication status. The display panel controller performs parsing when communication is normal, while the unit controller takes over parsing when communication is lost. This dynamic adaptation reduces system complexity by avoiding the need for dual independent parsing systems.
Solution Approach 2:
The state controller acts as an intermediary that sends control data to both the display panel controller and unit controller. This intermediary approach allows the system to maintain centralized control logic while enabling independent operation paths, resolving the contradiction between reliability and complexity.
3Manufacturing precision
If the display panel controller performs delay process, then the locking operation can be precisely timed, but the communication requirement increases system complexity
Solution Approach 1:
The display panel controller receives and stores delay information from the state controller in advance. When control is needed, it retrieves this pre-stored delay information and executes the delay process without requiring real-time communication, ensuring precise timing while reducing communication requirements.
Solution Approach 2:
The display panel controller performs the delay process independently using pre-stored delay information, without requiring continuous communication with other controllers. This self-service capability ensures precise timing execution while simplifying the communication architecture.
Data Source
AI summary
An equipment unit state controlling method and device, and an equipment unit. After receiving control data transmitted from a state controller, a unit controller detects whether the unit controller communicates with a display panel controller, in which the state controller transmits the control data to the unit controller and the display panel controller simultaneously. If the unit controller communicates with the display panel controller, the unit controller performs an operation on the equipment unit corresponding to instruction information transmitted from the display panel controller, and if the unit controller does not communicate with the display panel controller, the unit controller parses the control data by itself to obtain the parsing result and performs the operation on the equipment unit corresponding to the parsing result.
