Comprehensive Perception, Stable Operations and Maintenance | MXR04 Integrated Telemetry Terminal

The MXR04 is a low-power remote terminal unit (RTU) specifically designed for water‑conservation and pipeline‑network applications. It is ideally suited for scenarios such as drainage networks and hydrological‑water‑resource monitoring, enabling multi‑parameter data acquisition, edge computing, wireless communication, and remote control, while complying with industry‑standard protocols for the water‑conservation sector.

I. Product Positioning and Core Features

1) Positioning

► Ultra-low-power integrated RTU, suitable for unmanned field monitoring applications such as manholes, pipeline networks, river channels, and reservoirs.

2) Core Features

►Data Acquisition: Integrates sensors for water level, flow rate, rainfall, water quality, pressure, temperature, and more.

► Edge Computing: local data preprocessing (filtering, outlier removal, unit conversion), scheduled or event-triggered data acquisition, threshold-based alerts, and data packet completion.

►Wireless Communication: 4G/NB‑I►T, supporting protocols such as SL651‑2014, MQTT, and M►dbus, enabling one‑stop multi‑channel transmission to multi‑tiered platforms.

►Remote Operations and Maintenance: remote parameter configuration, firmware upgrades, and status diagnostics; supports Bluetooth and local serial‑port configuration.
