Product Introduction

Geodetic GNSS receiver

SP1000-BD

The geodetic GNSS receiver is a versatile deformation‑monitoring device that integrates a high‑precision GNSS module with MEMS sensors. It supports multi‑system, multi‑frequency signal reception, including BeiDou‑3, GPS, and GLONASS, and delivers millimeter‑level static monitoring as well as centimeter‑level dynamic monitoring. Equipped with an advanced intelligent fusion algorithm, the device combines satellite positioning data with inertial sensor information to enable continuous, reliable displacement monitoring in complex environments. It is widely applicable to geological hazard and engineering safety monitoring scenarios, such as landslides, subsidence, and mining‑area deformations.

APPLICATION FIELD

This solution targets potential geological hazard sites along railway corridors—such as slope faces, tunnel portals, and embankments—by deploying smart sensors including inclinometers, crack meters, GNSS devices, and rain gauges to establish an automated monitoring and early‑warning system. It collects real-time data on deformation, rainfall, and other parameters, transmitting it via multi‑link communication to a cloud platform, where intelligent algorithms perform analysis and issue tiered alerts. The system has been successfully implemented in projects such as the Xiang–Gui Line, the Nanning Railway Bureau’s flood‑control network, and the Huangbai Railway, significantly enhancing the railway sector’s capacity for preventing and mitigating geological hazards.

Geological Hazard Monitoring and Early Warning Solution for Railway Corridors

The smart port monitoring solution covers multiple aspects, including port equipment, cargo handling processes, yard safety, personnel operating procedures, environmental changes, port operational efficiency, and energy consumption. By collecting and analyzing data in real time, the system can promptly identify and address issues, thereby ensuring stable, safe, and efficient port operations. At the same time, monitoring and optimizing energy consumption helps ports reduce energy use and improve energy efficiency.

Smart Port Solution

By leveraging a variety of sensors and wireless communication devices, farm data can be transmitted in real time and automatically to the screens of agricultural managers, thereby establishing an integrated, IoT-based connection between farmers and their fields. Furthermore, the application of RFID and other tagging technologies enables the development of modern agricultural logistics systems for warehousing and transportation, facilitating effective monitoring and assurance of food safety. At the same time, the collection and networking of farm data support the monitoring and early warning of natural disasters, streamline regional management, and promote extensive information sharing and agricultural automation.

Smart Agriculture Cultivation Solutions

This solution is designed for scenarios such as tailings ponds, heap leaching sites, and industrial waste‑slag storage facilities in both metallic and non‑metallic mines. It deploys intelligent monitoring devices—including GNSS, piezometers, water level gauges, rain gauges, flume flow meters, inclinometers, crack meters, and video surveillance—to establish an online safety monitoring and early‑warning system for tailings facilities. By continuously collecting real‑time data on dam displacement, the phreatic line, pond water levels, seepage rates, rainfall amounts, and on‑site imagery, the system transmits this information via 4G, Beidou, or LoRa to a cloud‑based platform. Advanced stability analysis models then perform intelligent data interpretation and tiered warning assessments. When threshold values are exceeded, the system automatically issues alerts and activates on‑site alarm devices, providing round‑the‑clock, comprehensive technical support for safe tailings‑pond operations, flood‑control and emergency management, thereby effectively mitigating the risk of dam failures.
