Passenger Conveyor Controller Handshake for OS Status and Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In new installations of passenger conveyor systems like elevators and escalators, manually uploading the controller configuration to enable communication with the management service is time-consuming after a new software installation.
Innovation Solution
A passenger conveyor system with a maintenance controller that transmits signals to identify communication capabilities, determines the operating system status, and issues alerts or updates as needed, utilizing protocols like CAN and serial over networks such as CAN and cloud services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual upload of controller configuration is used, then the management service can communicate with the controller, but significant time is required for the action
Solution Approach 1:
The controller automatically performs self-identification by transmitting its communication capabilities and operating system status to the maintenance controller without requiring manual intervention. This self-service mechanism eliminates the time-consuming manual upload process while ensuring the management service can communicate with the controller.
Solution Approach 2:
The controller pre-transmits its communication capabilities and configuration information to the maintenance controller before actual communication is needed. This preliminary action ensures that when the management service needs to communicate with the controller, the information is already available, eliminating delays.
2Adaptability or versatility
If multiple protocols are used for communication, then compatibility with different device controllers is improved, but system complexity increases
Solution Approach 1:
The maintenance controller is designed with multi-functionality to support multiple communication protocols (CAN, serial, and other I2C-based protocols). This universal capability allows the same controller to communicate with different types of device controllers using different protocols, improving adaptability without requiring separate dedicated controllers for each protocol type.

AI summary
An passenger conveying system for confirming a status of an operating system of a device controller of a passenger conveyor, having: a maintenance system; a maintenance controller coupled to the device controller via a first network and to the maintenance system via a second network, wherein the maintenance controller is configured to: transmit a first signal to the device controller utilizing one or more of a plurality of protocols to identify the communication capabilities of the device controller; transmit a second signal including current parameters of the operating system to the maintenance system, upon receiving a responsive signal from the device controller, to determine the status of an operating system; and issue an alert to the maintenance system after failing to receive a responsive signal from the device controller.
