Autonomous Point Device State Querying for Master Controller Complexity Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As security systems and home automation systems incorporate more point devices, the complexity of the master controller increases, leading to delays, errors, and limited versatility due to the need for explicit commands and manual interaction for each device, which affects power management and system reliability.
Innovation Solution
Point devices are configured to automatically determine the current system state by querying external devices and modify their operation accordingly, reducing the complexity of the master controller and enabling autonomous power management, even in the absence of timely commands from the master controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the master controller manages more point devices, then the system coverage and monitoring capability improve, but the master controller complexity increases leading to delays and errors
Solution Approach 1:
The patent divides the control functionality into two parts: the master controller handles system-level coordination while individual point devices handle their own operational decisions. This segmentation reduces the master controller's complexity by eliminating the need for it to manage every device's operational state directly.
Solution Approach 2:
Point devices autonomously determine the current system state by querying external devices and automatically modify their operation based on this state information. This self-service capability reduces the burden on the master controller, allowing it to scale without proportionally increasing complexity.
2Adaptability or versatility
If the master controller manages more point devices, then the system coverage improves, but processing delays and errors increase
Solution Approach 1:
Point devices independently query external devices for system state information and automatically adjust their operation without waiting for master controller commands. This eliminates processing delays associated with master controller bottlenecking.
Solution Approach 2:
Point devices proactively query for system state information before needing to make operational decisions, enabling them to anticipate and respond to system state changes without waiting for master controller instruction.
3Measurement precision
If explicit commands are sent to each point device, then precise control is achieved, but the need for manual interaction increases reducing ease of operation
Solution Approach 1:
Point devices automatically determine system state and adjust their operation without requiring explicit commands or manual interaction. This maintains precise control through autonomous decision-making while eliminating the operational burden of manual device-by-device configuration.
Solution Approach 2:
Point devices query external devices for system state information and use this feedback to automatically modify their operation. This closed-loop approach enables precise control through autonomous response to system conditions rather than manual commanding.
4Device complexity
If the master controller manages all device operations, then centralized control is maintained, but system reliability decreases when the master controller is unavailable
Solution Approach 1:
The patent segments control authority from the master controller to individual point devices. Each point device can independently determine system state and adjust its operation, maintaining functional autonomy even when the master controller is unavailable.
Solution Approach 2:
Point devices autonomously query external devices for system state information and self-adjust their operation without requiring master controller availability. This distributes reliability across multiple independent nodes rather than creating a single point of failure.

AI summary
Methods and systems for operating a point device included in a system of point devices. One method includes transmitting a query, with a transceiver included in the point device, to at least one device external to the point device for system state information and receiving, with the transceiver, a response from at least one device external to the point device in response to the query. The method also includes determining, with an electronic processor included in the point device, a current state of the system of point devices based on the received response and automatically modifying, with the electronic processor, operation of the point device based on the current state of the system of point devices.
