Elevator Communication Device for Unmanned Device Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned devices face challenges in communicating with the cloud platform due to poor network signals within elevator cars, leading to difficulties in determining whether they have entered the elevator and continuing their journey.
Innovation Solution
An elevator controlling communication device is introduced to provide network access within the elevator car, allowing the unmanned device to establish a communication connection and send requests directly to the elevator controlling device, ensuring real-time information exchange and accurate elevator operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the unmanned device communicates with the cloud platform through remote connection, then elevator scheduling and monitoring can be achieved, but network signals within elevator cars are poor leading to communication failures
Solution Approach 1:
The patent introduces an elevator controlling communication device as an intermediary component installed within the elevator car. This device receives elevator control signals and communicates with the unmanned device through local wireless connection, acting as a mediator between the cloud platform and the unmanned device. When remote communication fails due to poor signals, the intermediary device ensures continuous local communication, resolving the contradiction between achieving remote scheduling and maintaining communication reliability in poor signal environments.
2Extent of automation
If the unmanned device sends elevator call requests through the cloud platform, then centralized scheduling is achieved, but real-time information exchange and accurate operation control are difficult
Solution Approach 1:
The patent segments the elevator control system into two parts: centralized cloud platform for scheduling decisions and local elevator controlling communication device for real-time execution. The cloud platform handles high-level scheduling automation, while the local device processes real-time communication and control signals immediately. This segmentation allows both centralized automation and real-time response to coexist, resolving the contradiction between automated scheduling and real-time response requirements.
3Productivity
If the unmanned device enters the elevator without reliable communication, then elevator taking process can proceed, but the device cannot determine whether it has entered the elevator
Solution Approach 1:
The patent implements a feedback mechanism where the elevator controlling communication device continuously monitors and reports the unmanned device's status within the elevator car. The device receives acknowledgment signals confirming successful entry, and can detect when the unmanned device has left the elevator. This feedback loop ensures that entry status information is maintained throughout the elevator journey, resolving the contradiction between maintaining productivity and preventing information loss about entry status.
