Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator systems face challenges in reliably processing elevator calls, particularly in ensuring that calls are received and managed effectively across multiple wireless communication modules, which can lead to inefficiencies and potential failures in call assignment.
Innovation Solution
A distributed processing system is implemented, where multiple wireless communication modules are deployed in the elevator service area, each associated with call units, capable of independently assigning call units based on operation states and communicating with terminal devices to manage elevator calls, reducing reliance on centralized processing and enhancing system robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized processing system is used for elevator call management, then call assignment can be controlled from a single point, but system robustness deteriorates and data transmission overhead increases
Solution Approach 1:
The patent divides the centralized call processing function into multiple distributed wireless communication modules deployed across different locations in the elevator service area. Each module can independently perform call assignment operations, eliminating the single point of failure in centralized systems and improving overall system robustness through spatial distribution of processing capabilities.
Solution Approach 2:
The patent introduces wireless communication modules as intermediary devices between terminal devices and call controllers. These modules receive elevator calls from terminal devices, perform local call assignment based on operation states, and communicate with relevant call controllers, thereby distributing the processing load and reducing direct communication overhead between terminal devices and central controllers.
2Reliability
If multiple wireless communication modules are deployed for call processing, then system robustness improves, but device complexity increases
Solution Approach 1:
The patent designs wireless communication modules with multi-functional capabilities, allowing each module to perform multiple operations including receiving elevator calls from terminal devices, determining operation states of call units, performing call assignment decisions, and communicating with multiple call controllers. This universal design reduces the need for specialized dedicated devices for each function, thereby managing complexity while maintaining robustness through distribution.
3Loss of energy
If call assignment is performed locally by wireless communication modules, then data transmission overhead is reduced, but communication coordination complexity increases
Solution Approach 1:
The patent implements local call assignment processing where each wireless communication module independently determines operation states of associated call units and performs call assignment decisions based on local information and predefined criteria. This local processing approach minimizes the need for continuous data transmission between central controllers and individual modules, reducing overall data transmission overhead while maintaining efficient call management.
