## What is ayi9?

Ayi9 IoT Management Platform
Built on the wlink IoT protocol, Ayi9 focuses on full-lifecycle management of UPS, air conditioners, voltage regulators, and solar systems. With "remote, real-time, intelligent" features, it’s a core O&M tool across industries.
I. Core Functions
1. Equipment Monitoring
It collects/analyzes key data in real time (via dashboards/reports), covering:
UPS: Input/output voltage/current, battery level, fault alarms.
Air conditioners: Mode, temp (set/actual), wind speed, component status.
Voltage regulators: Input fluctuation, output stability, load rate.
Solar systems: PV power generation, inverter efficiency, battery status.
2. Remote/Local Operation
Users control equipment anywhere:
UPS: Remote on/off, mode switching, parameter adjustment.
Air conditioners: Temp setting, mode/wind speed change, scheduled on/off.
Voltage regulators: Output calibration, protection activation.
Solar systems: Inverter control, battery threshold adjustment.
II. Technical Foundation: wlink Protocol
Low latency: Fast data sync and command execution.
High reliability: Anti-interference, stable connection in complex environments.
Security: Encrypted transmission, preventing tampering/leakage.
III. Application Scenarios
Widely used in:
Telecom: Equipment room UPS/air conditioner monitoring.
Base stations: UPS/solar system management.
Finance: ATM voltage regulator/UPS monitoring.
Transportation: Expressway toll system UPS monitoring.
Energy: Solar power station equipment management.
