Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building automation systems often experience issues with wired and wireless devices freezing or locking up due to hardware or software faults, leading to communication dead spots and incomplete control implementation.
Innovation Solution
A method and system for regularly polling or querying automation components within a building automation system to initiate a reset function based on predefined criteria, utilizing a communication link between components to detect changes and activate a reset, ensuring continuous operation and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If devices are operated continuously within the building automation system, then system productivity is improved, but device reliability deteriorates due to freezing or locking up from hardware or software faults
Solution Approach 1:
The system performs preliminary actions by continuously polling devices and detecting communication link changes before complete device failure occurs. When a device becomes unresponsive or freezes, the system detects the communication breakdown and automatically initiates a reset function, preventing prolonged operational failures and maintaining overall system productivity.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring communication links between automation components. When a device fails to respond or becomes unresponsive, the polling mechanism detects this feedback signal, triggering an automatic reset function to restore device reliability without manual intervention.
2Reliability
If manual intervention is used to reset frozen devices, then device reliability is improved, but loss of time increases due to service requests and technician deployment
Solution Approach 1:
The system implements self-service by automatically detecting when devices become unresponsive through continuous polling and autonomously initiating reset functions without requiring technician intervention. This eliminates service requests and reduces loss of time while maintaining device reliability through automated fault recovery.
Data Source
AI summary
A method for wireless communication within a building automation system is disclosed. The method includes establishing a communications link between a first automation component and a second automation component, detecting a change in the communications link at the second automation component, and initiating a reset function on the second automation component in response to the detected change in the communications link. A building automation system is further disclosed. The system includes a first automation component, a second automation component in communication with the first automation component via a communication link. The second automation component further includes a reset function stored on a memory and executable by a processor in communication with the memory, such that the reset function is activated in response to a change in the communications link.
