Solution Overview
Problem
Existing methods for setting parameters in electronic motor controls of hoisting equipment require additional accessories and equipment, leading to high costs and limited variability, especially when adapting to different applications or changing circumstances.
Innovation Solution
A method that uses the existing hoisting switch, lowering switch, and emergency shutoff switch, in conjunction with the microprocessor, to automatically run through and display parameters, allowing binary selection and change without additional accessories, enabling easy and comprehensive parameter adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rewiring by means of plug-in patches and switch bays is used for parameter adjustment, then parameter setting is achieved, but device complexity and cost increase significantly
Solution Approach 1:
The control system performs self-configuration through automatic parameter recognition and setup. The microprocessor automatically identifies the type of hoisting equipment, retrieves appropriate default parameters, and configures the control system without requiring manual rewiring or external assistance, thereby eliminating the need for complex plug-in patches and switch bays
Solution Approach 2:
The invention changes the approach from physical parameter adjustment through rewiring to digital parameter configuration. Instead of physically modifying connections, the system uses software-based parameter storage and retrieval mechanisms, allowing all adjustments to be made through digital means without any physical rewiring
2Ease of operation
If data interfaces with parameterization terminal or PC are used for parameter adjustment, then parameter setting is achieved, but additional equipment and overhead costs are required
Solution Approach 1:
The existing microprocessor and display in the control system are made multi-functional by enabling them to perform both normal control operations and parameter configuration. The same hardware components serve dual purposes, eliminating the need for separate parameterization terminals or PCs while maintaining full parameter adjustment capability
Solution Approach 2:
The control system configures itself using its existing microprocessor and display without requiring external computing equipment. The system automatically performs parameter recognition, retrieval, and configuration tasks that would otherwise require a separate parameterization terminal or computer interface
3Adaptability or versatility
If comprehensive parameter adjustment is enabled, then adaptability is improved, but device complexity increases
Solution Approach 1:
The parameter configuration process is segmented into distinct phases: equipment type recognition, default parameter retrieval, and individual parameter adjustment. This segmentation allows comprehensive adaptability to be achieved through a structured, manageable process rather than a monolithic complex system
Solution Approach 2:
Default parameters are pre-stored in the microprocessor memory for various types of hoisting equipment. Before actual parameter adjustment is needed, the system automatically retrieves and loads the appropriate default settings, preparing the control system for configuration without requiring complex real-time calculations or additional processing
