Bus electromagnetic loop self-adapting adjusting method and device of fire alarm controller

Abstract

This application provides a method and device for adaptive adjustment of the electromagnetic loop immunity of a fire alarm controller bus, relating to the field of information transmission technology. The method includes: monitoring communication on the fire alarm controller bus; identifying electromagnetic interference based on an initial signal quality dataset, determining the electromagnetic loop interference parameters of the bus, and performing feature analysis; adaptively optimizing bus transmission based on the electromagnetic loop interference feature parameters and the initial signal quality dataset; dynamically reconstructing bus communication using an anti-interference transmission strategy; determining the signal quality dataset based on the reconstructed bus communication; verifying the signal quality dataset based on the initial signal quality dataset; and formulating an electromagnetic loop adjustment scheme based on the verification results to adaptively adjust the electromagnetic loop immunity of the fire alarm controller bus. This application solves the technical problem of poor anti-interference performance of the fire alarm controller bus in existing technologies, achieving a significant improvement in anti-interference effectiveness.
