Anti-interference water control terminal control method and system with abnormality alarm

By time-marking and threshold-based discrimination of the water shortage, anti-magnetic, and flow sampling interface signals of the intelligent water control terminal, a hardware alarm event set is generated. Board-level partitioning and power isolation processing are then implemented to solve the problem of unstable alarm signals of the water control terminal under strong interference environment, thus achieving stable and reliable alarm processing.

AI Technical Summary

Technical Problem

Existing intelligent water control terminals suffer from unstable alarm sensor interface signals, scattered interface recognition and event mapping, and disconnected partition layout processing and power isolation processing under conditions of water shortage, strong magnetic interference, and abnormal flow. This results in discontinuous alarm message generation and uploading processing, making it difficult to achieve stable alarm processing.

Method used

By reading the water shortage, antimagnetic, and flow sampling interface signals of the water control terminal in parallel, performing time stamp alignment and threshold discrimination, generating a hardware alarm event set, performing board-level partitioning layout, configuring power ground interference immunity and power isolation, laying a metal shielding structure, generating a board-level electromagnetic compatibility configuration set, and finally uploading alarm messages via Bluetooth or 4G channels.

Benefits of technology

It achieves stability and reliability of alarm signals in strong interference environments, ensures data consistency and traceability throughout the entire chain from event acquisition to alarm reporting, avoids false alarms or missed alarms, and realizes a complete closed loop from detection to handling.

Abstract

This invention relates to the field of intelligent water control terminal control and electromagnetic compatibility processing technology, and particularly to an anti-interference water control terminal control method and system with abnormal alarm. The method includes: reading raw signals in parallel from water shortage, anti-magnetic, and flow sampling interfaces; processing and mapping these signals into alarm events and writing them into a hardware alarm event set; performing board-level partitioning layout based on the information in the event set to generate a partitioning layout configuration set; configuring decoupling units, laying grounding wires and copper plating, and setting multiple grounding nodes accordingly; assigning power supplies to each detection interface to an analog power path and power supplies to the main control and communication modules to a digital power path, configuring filtering units and isolation nodes; laying grounding copper foil and vias for the crystal oscillator, and configuring metal shielding structures for key modules; reading alarm signals based on the obtained configuration set and encapsulating them into alarm messages, uploading them via Bluetooth or 4G channels, receiving management results, and generating a terminal alarm processing status. This invention improves the anti-interference capability and alarm reliability of the water control terminal through event-driven board-level layout and power supply link isolation.
