Hierarchical Sensor Data Dispatcher for Real-Time Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large volumes of sensor data from distributed sensor networks can overwhelm networks and users, leading to delays and the transmission of stale data, reducing the utility and value of the data for users.
Innovation Solution
Organizing sensor networks in a hierarchical structure and providing a graphical user interface to allow users to selectively receive data from specific sensors, using a sensor data dispatcher to transmit real-time data through a real-time messaging system, thereby reducing unnecessary data transmission and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all sensor data is transmitted to the server, then complete data collection is achieved, but network bandwidth is overwhelmed and transmission delays occur
Solution Approach 1:
The patent extracts and transmits only the necessary sensor data to the server based on user selections, rather than transmitting all sensor data. The sensor data dispatcher filters data streams according to selected sensors, extracting only relevant data for transmission, which reduces network bandwidth consumption while maintaining data completeness for the needed parameters.
2Loss of information
If all sensor data is transmitted, then comprehensive data is available, but the user is overwhelmed by the volume of data
Solution Approach 1:
The patent applies local quality by allowing users to select specific sensors or data streams based on their local needs and preferences. The system provides different data quality levels to different users based on their selections, rather than providing uniform comprehensive data to all users. This makes the data more usable and relevant to each user's specific application.
3Loss of information
If sensor data is transmitted over the network, then data delivery is achieved, but network delays cause data to become stale
Solution Approach 1:
The system extracts and transmits only the essential sensor data directly to users without unnecessary network routing delays. By filtering data at the source and transmitting only selected streams, the system reduces transmission time and maintains data freshness while still achieving reliable data delivery.
4Loss of energy
If selective sensor data transmission is implemented, then network efficiency is improved, but system complexity increases
Solution Approach 1:
The patent introduces a sensor data dispatcher as an intermediary component that manages the complexity of selective data transmission. This mediator sits between the sensors and the server/users, handling the filtering and routing logic. While this adds a system component, it centralizes the complexity management and provides efficient network resource usage through intelligent data selection.

AI summary
Methods and systems for operating a sensor network are provided. In one example, a server may provide graphical data representing a hierarchical sensor network for displaying at a client device. The server may receive a selection to display sensor data from a first node of the nodes of the hierarchical sensor network and determine, based on the selection, a hierarchical sensor label associated with one or more first sensors of the hierarchical sensor network corresponding to the first node. The server may also receive a plurality of messages including sensor data generated by a plurality of sensors of the hierarchical sensor network from an in-bound real-time message processor, and identify a first set of messages based on the hierarchical sensor label. The server may extract the sensor data from the first set of messages and provide the sensor data for displaying at the client device.
