Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevator communication systems require significant cost and invasive modifications to replace Bluetooth modules, necessitating a solution that minimizes wiring and preserves existing investments.
Innovation Solution
An elevator communication system that uses a combination of first and second wireless processing units, where the first unit receives requests via wireless or wired interfaces and forwards them to the elevator controller through a wired communication interface, reducing the need for new wiring and allowing existing cables to be reused.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a brand new Bluetooth module is used for elevator communication, then wireless communication capability is improved, but system cost and modification complexity increase
Solution Approach 1:
The existing elevator communication system is designed to support multiple communication modes (wired and wireless) through a unified architecture. The controller can selectively use either wired connections or wireless Bluetooth/Wi-Fi modules depending on availability, making the system universally adaptable without requiring complete redesign for wireless functionality
Solution Approach 2:
A wireless communication module acts as an intermediary between the elevator control system and external devices. This module interfaces with existing wired infrastructure while providing wireless connectivity, thereby enabling wireless communication without directly modifying core elevator components
2Ease of manufacture
If existing wiring is reused for wireless communication, then installation cost is reduced, but communication reliability may be affected
Solution Approach 1:
The communication system is segmented into independent functional modules: wireless communication module, wired communication interface, and controller. This segmentation allows the wireless module to handle wireless traffic while wired connections provide redundant reliable communication paths, ensuring overall system reliability without requiring complete rewiring
3Adaptability or versatility
If invasive modifications are made to existing elevator devices, then wireless communication is enabled, but system disruption and installation time increase
Solution Approach 1:
The wireless communication module is designed as a pre-assembled unit with all necessary components (antenna, processor, communication protocols) integrated before installation. This preliminary preparation allows for quick plug-and-play installation in existing elevator systems without requiring on-site customization or extensive modification work
Solution Approach 2:
The wireless communication module autonomously manages communication protocols, signal processing, and device pairing without requiring complex configuration or intervention during installation. The module self-configures to work with existing elevator infrastructure, minimizing installation time and disruption

AI summary
The present application relates to an elevator communication system (10) and method, a storage medium. The system (10) comprises: a first wireless processing unit (101, 102) configured to receive a request for elevator in a wired manner, and configured to forward the request for elevator in a wireless manner; and a second wireless processing unit (103) configured to receive the request for elevator from the first wireless processing unit (101, 102) in a wireless manner, and configured to forward the request for elevator to an elevator controller (133) in a wired manner. By such system, the elevator can be called in a wireless manner.
