Hero V9 Series: Low Power Self-Powered Portable Remote Telemetry Terminal (RTU)
The Hero V9 Series Self-Powered Portable Remote Telemetry Unit is an ultra-low power, IP68 waterproof RTU designed for demanding field operations and underground environments like DMA (District Metering Area) systems. It enables sophisticated data strategies including "regular timed acquisition + abnormal high-frequency acquisition" and "routine limit alarm + instantaneous mutation alarm" for flow, pressure, and level sensors, providing a professional, scenario-specific solution for wireless measurement and control.
Core Design & Application for Smart Water Systems
This integrated RTU combines a dual-core processor, a large 114Ah lithium battery, e-ink display, and multi-interface acquisition modules into a single, portable unit. It is the optimal solution for implementing high-frequency acquisition and high-reliability wireless telemetry in smart water perception layer equipment, particularly addressing the critical need for monitoring low night flow in DMA leakage analysis.
The device's professional functions are tailored for specific scenarios, ensuring reliable data collection and alarm management even in the most challenging underground or remote locations where power and access are limited.
Key Features & Technical Advantages
Ultra-Low Power Design
Sleep current <50μA. With 15-min collection & 2-hour reporting, battery endurance is ≥4 years.
IP68 Waterproof Rating
Features silicone sealing, potting, and a waterproof antenna for long-term submerged operation.
Large Capacity Power
Standard 114Ah@3.6VDC LiFePO4 battery, with options for external expansion packs.
Dual-Core Processor
ARM Cortex-M3 + MSP430 CPUs with an RTOS for enhanced reliability and stability.
High-Precision 5PPM Clock
Ensures clock error <1 second, critical for timed functions and data sequence integrity.
Flexible 4G Communication
Industrial 4G module compatible with major carriers, with optional cloud platform software.
Reliable Communication and Intelligent Firmware Management
The RTU utilizes a self-developed, lightweight proprietary IP communication technology optimized for embedded systems, offering small code size, low memory footprint, and high operational efficiency. Its industrial-grade 4G design provides universal network compatibility.
For easy maintenance, the Hero V9 RTU firmware supports wireless remote upgrades via Bluetooth or 4G, facilitating feature iteration and reducing long-term operational costs. Parameters can be flexibly configured through serial port, APP, or Web platform.
Advanced Data Acquisition and Alarm Functions
Beyond standard limit alarms, this remote telemetry terminal supports instantaneous mutation alarm configuration for flow, pressure, and liquid level. For DMA night flow analysis, it can be configured to automatically switch from regular to ultra-high-frequency (second-level) collection cycles during specified night hours, ensuring accurate data for leakage algorithms.
The unit features large-capacity data storage with 16M Flash memory, capable of storing over 50,000 historical data points. It also supports multi-center reporting to up to 3 data centers in either multi-active or primary/backup mode for maximum data reliability.
Comprehensive Sensor Integration Capabilities
The Hero V9 portable RTU is equipped with versatile input interfaces to connect with a wide array of field instruments. It supports one RS485 interface for standard MODBUS-RTU, CJ-188, and other meter protocols.
An independent pulse acquisition module handles three switch signal inputs, compatible with Hall effect and reed switch signals from pulse mechanical meters. Additionally, two analog interfaces support connection to pressure or level sensors, accepting voltage (0-5V) and current (4-20mA) signals with independently configurable ranges.
User Interface & Installation
E-Ink Display and Easy Installation Design
A standard e-ink display with magnetic control buttons provides clear visual status for signal strength, battery voltage, process variables, and cycle settings. This low-power display is ideal for field viewing.
The RTU comes with a mounting bracket and a unique buckle connection, allowing for direct installation on instrument well walls. This design enables quick secondary disassembly, greatly simplifying both initial construction and subsequent maintenance work.
