Solution Overview
Problem
Wireless mesh networks, particularly those used in outdoor luminaires and air-conditioning systems, are susceptible to electromagnetic interference from load drivers, leading to reduced communication efficiency and stability due to outdated routing tables and increased noise levels.
Innovation Solution
A device and method that adjust the communication mode of nodes in a wireless network based on the operation state of load units, such as increasing transmit power or changing communication protocols, to mitigate interference effects and maintain reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the lamp driver is switched on to provide lighting, then the lighting function is achieved, but electromagnetic interference increases causing reduced communication reliability
Solution Approach 1:
The communication mode is dynamically adjusted based on the operation state of the load unit. When the lamp driver is switched on, the system automatically switches from a first communication mode to a second communication mode, making the communication parameters adaptive to the electromagnetic environment rather than static.
Solution Approach 2:
The invention changes communication parameters (such as transmit power, modulation scheme, or protocol) based on the operation state of the load unit. By detecting whether the lamp driver is on or off, the system selects appropriate communication parameters to maintain reliability under varying electromagnetic interference conditions.
2Reliability
If the communication mode is adjusted to mitigate interference, then communication reliability is maintained, but additional control complexity is introduced
Solution Approach 1:
The node performs self-adjustment of its communication mode based on its own operation state. The control unit detects when the load unit is switched on or off and automatically selects the appropriate communication mode without requiring external intervention or complex centralized control, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The system uses feedback from the operation state of the load unit to adjust the communication mode. The control unit monitors the state of the lamp driver and uses this information to select appropriate communication parameters, creating a closed-loop control system that maintains reliability while keeping the control mechanism relatively simple.
