Door Arrangement Maintenance via Mobile Data Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote-controlled building automation systems for door arrangements do not allow for effective remote maintenance, as technicians lack access to necessary information and data for troubleshooting and updating control devices.
Innovation Solution
A maintenance system with a control device featuring a motor control unit, non-temporary memory for door data, and bidirectional data connections enabling a mobile maintenance device to access and update door data, ensuring that maintenance data is synchronized with a central maintenance data memory for efficient troubleshooting and updating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote-controlled building automation system is used for door arrangements, then the operation of door drives and lighting systems can be controlled remotely via mobile devices, but maintenance of the control device is not possible and technicians lack access to necessary information for troubleshooting
Solution Approach 1:
A mobile maintenance device serves as an intermediary between the control device and the central maintenance data memory. This intermediary enables technicians to access door data from the control device's non-temporary memory and maintenance data from the central memory, facilitating remote maintenance without requiring physical intervention in the control device itself.
Solution Approach 2:
The system creates a copy of the door data storage architecture by implementing a non-temporary memory in the control device that mirrors the structure of the central maintenance data memory. This allows the mobile maintenance device to access and manipulate data locally without needing to physically access the control device's internal components.
2Reliability
If technicians lack access to door data and maintenance information, then system security is maintained, but troubleshooting and updating control devices becomes impossible
Solution Approach 1:
The mobile maintenance device acts as a secure intermediary that authenticates and authorizes access to door data and maintenance information. It establishes bidirectional data connections that allow technicians to retrieve necessary information while maintaining security protocols, enabling maintenance without compromising system security.
Solution Approach 2:
The data access system is segmented into different levels: door data stored in the control device's non-temporary memory and maintenance data stored in the central maintenance data memory. The mobile maintenance device accesses these segmented data stores through controlled bidirectional connections, allowing selective access to different data types based on maintenance needs.
3Stability of the object's composition
If maintenance data is stored centrally, then data consistency and updates are improved, but access time and maintenance speed decrease due to lack of local data availability
Solution Approach 1:
Door data is extracted from the central maintenance data memory and stored locally in the control device's non-temporary memory. This extraction allows the mobile maintenance device to access and download door data quickly from the local memory during maintenance operations, while still maintaining the ability to update data from the central memory when needed.
Solution Approach 2:
Door data is preliminarily stored in the control device's non-temporary memory before maintenance operations are needed. This preliminary action ensures that when a technician performs maintenance, the necessary door data is already available locally for quick access and download, reducing maintenance time while maintaining data consistency with the central memory.
Data Source
AI summary
A maintenance system for a door arrangement. The door arrangement includes a door member and a drive unit configured to drive the door member. The maintenance system includes a control device comprising a motor control unit configured to control the drive unit and a non-temporary memory configured to store door data, a central maintenance data memory comprising maintenance data for at least one of configuring, monitoring and modifying the control device, a first bidirectional data connection, a second bidirectional data connection, and a mobile maintenance device. The door data is retrievable from the non-temporary memory. The mobile maintenance device is configured to be coupled to the non-temporary memory of the control device via the first bidirectional data connection to maintain the door arrangement, and to be directly or indirectly coupled to the central maintenance memory via the second bidirectional data connection.
