Remote Zigbee Network Monitoring via Cloud Decoded Event Logs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ZIGBEE networks lack effective remote monitoring capabilities, making it difficult to detect malfunctioning devices without direct access and requiring specialized expertise, especially in residential settings where such expertise is often unavailable.
Innovation Solution
A system and method for remotely monitoring ZIGBEE networks by storing event logs on devices, transmitting them to a gateway, decoding into human-readable format, and uploading to a cloud server for analysis, allowing remote access and analysis via smartphones or other devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If direct querying of gateway or sensor is used to determine device functionality, then device operation can be monitored, but operator must be co-resident with gateway or sensor requiring on-site presence
Solution Approach 1:
The patent introduces an intermediary system comprising a gateway device, cloud server, and remote device that mediates between the operator and the ZIGBEE network devices. The gateway collects event logs from sensors, transmits them to the cloud server for processing, and enables remote devices to access monitoring information without requiring operator presence at the device location.
2Measurement precision
If specialized expertise is required to monitor network operation, then accurate monitoring can be achieved, but such expertise is often not available in residential settings
Solution Approach 1:
The system enables self-service monitoring through automated event log collection, transmission, and processing. The gateway device automatically monitors network events, the cloud server automatically processes and stores the data, and remote devices automatically retrieve monitoring information, eliminating the need for specialized human expertise in residential deployments.
Solution Approach 2:
The system performs preliminary actions by pre-configuring the gateway device with monitoring capabilities and event log collection mechanisms. The infrastructure is prepared in advance with automated processes for data collection, transmission, and storage, so that monitoring can occur without requiring specialized knowledge at the time of deployment.
3Ease of operation
If event logs are stored and transmitted from network devices to gateway and then to cloud server, then remote monitoring capability is achieved, but system complexity increases
Solution Approach 1:
The patent segments the monitoring system into distinct functional modules: event log storage at network devices, data transmission to gateway, processing and storage at cloud server, and retrieval at remote devices. Each component has a specific function, reducing overall system complexity through modular design and clear separation of responsibilities.
Data Source
AI summary
A system and method for remotely monitoring and analyzing devices on a wireless network, such as a ZIGBEE® network, is disclosed. The devices store event logs in a memory device whenever certain events occurs. These event logs are transmitted to a gateway device. The gateway device may operate in standalone mode or in network coprocessor (NCP) mode. The gateway device may then decode the event logs into a human readable output. This human readable output may then be uploaded to a server in the cloud, where further analysis of the human readable output may be performed. This information may then be retrieved by remote devices, such as smart phones. In other modes, the event logs are uploaded to the server in the cloud and the decoding is performed in the cloud.
