Movable Barrier Gateway Delay for Local Command Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Movable barrier systems face conflicts when both local and remote commands are received simultaneously, potentially leading to unsafe operation due to the lack of coordination between local and remote control signals.
Innovation Solution
A movable barrier gateway device that receives remote commands, delays signal transmission for a predetermined time, detects movement during this period, and ignores the remote command if local movement is detected, ensuring safe operation by prioritizing local commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote command is received to move the movable barrier, then the barrier can be operated remotely for convenience, but a conflict may arise if a local command is received during the predetermined time period, causing unsafe operation
Solution Approach 1:
The system performs a preliminary check by detecting whether the barrier is already in motion before executing a remote command. A predetermined time period is established after receiving a remote command during which local motion is detected. If motion is detected during this period, the remote command is ignored, preventing conflicting operations and ensuring safe barrier control.
2Reliability
If the barrier waits for a predetermined time period before executing remote commands to allow for imminent movement notification, then safety notification is improved, but the response time for legitimate remote commands is delayed
Solution Approach 1:
The system dynamically adjusts its response based on real-time conditions. Rather than applying a fixed delay to all remote commands, the system only waits for the predetermined time period when necessary to detect local motion. If no motion is detected during this period, the command executes immediately after the brief wait, optimizing both safety and responsiveness.

AI summary
In one embodiment, a method conducted by a movable barrier gateway device is disclosed for controlling a movable barrier, comprising receiving, by a communication interface, a remote command from a remote control device to move the movable barrier, the remote command sent over a network, delaying transmission of a signal to a movable barrier controller to move the movable barrier, by a processor, for a predetermined time period after the remote command is received, detecting movement of the movable barrier within the predetermined time period by a barrier movement detector, and ignoring the remote command by the processor in response to detecting movement of the movable barrier within the predetermined time period.
