Air Mover Communication Upgrade Module Using Escape Sequence Detection

The communication module is designed to work with existing three-wire and four-wire air mover configurations by interpreting standard signals (PWM, tachometer) in multiple ways. It can detect escape sequences within these standard protocols to initiate two-way communication, allowing a single module to provide both traditional control and advanced communication capabilities without requiring separate dedicated communication wires or protocols.

The communication module acts as an intermediary between the processing component and the air mover motor controller. It intercepts and analyzes signals on existing wires, detects escape sequences, and facilitates bidirectional communication by translating between the standard air mover protocol and higher-level communication protocols, thereby enabling enhanced functionality without modifying the fundamental three-wire or four-wire architecture.

The intelligent fan functionality is segmented into a separate, removable communication module that can be independently manufactured and tested. This module can be optionally installed in the air mover connector, allowing manufacturers to produce both traditional and intelligent versions of air movers using the same base motor controller, thereby simplifying the manufacturing process while still providing upgraded capabilities where needed.

The system provides dynamic configurability where the communication module can be selectively installed or removed based on specific application requirements. The module itself can dynamically detect the presence of an escape sequence capability in the connected air mover and adapt its communication mode accordingly, allowing the system to operate intelligently only when the enhanced capability is present, thus maintaining ease of manufacture for standard units while enabling upgrades where required.

The communication module is designed to be universally compatible with both three-wire and four-wire air mover configurations by interpreting standard PWM and tachometer signals. It detects escape sequences within these existing protocols to initiate two-way communication, allowing the same module to work across different wire configurations without requiring modifications to the underlying electrical architecture or connector types.

Instead of modifying the air mover or connector to add communication capability, the invention inverts the approach by using the communication module to interpret and repurpose existing signals on standard wires. The module detects escape sequences embedded within normal control signals and facilitates bidirectional communication by translating these standard protocols, thereby enabling enhanced functionality without changing the fundamental electrical architecture that the air mover was designed to support.
