Product Introduction

Vibrating-wire piezometer

The vibrating‑wire piezometer is a pore‑water pressure measurement device based on the vibrating‑wire sensing principle. It is designed for long-term installation in soil, concrete dams, or foundations to monitor seepage pressures and water‑level fluctuations. The sensor features a stainless‑steel construction and a thermally stable design, offering high accuracy, low drift, and excellent corrosion resistance. When paired with an intelligent data‑acquisition system, it enables remote calibration, fault diagnosis, and seamless integration with cloud platforms, making it widely used in hydraulic engineering, geological hazard monitoring, and geotechnical applications.

APPLICATION FIELD

Railways are hailed as the bridge that propels a nation toward modernization and represent an indispensable pathway for developing a modern transportation system. As China enters a critical phase of economic development, the railway network plays an exceptionally vital role in driving economic growth, improving people’s livelihoods, and supporting national defense. Rail travel offers a remarkably fast and convenient mode of transportation; accordingly, the effective monitoring of railway infrastructure—particularly slope stability—has become a pressing priority.

Monitoring and Early Warning Solution for Geological Hazards and Structural Safety Along Railway Lines

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

Tailings are the solid waste remaining after ore has been extracted from a mine, and their treatment typically involves hydraulic beneficiation, tailings pond impoundment, and other processes. However, if not properly treated and managed, tailings can pose potential risks to the environment and human health. Common causes of tailings dam failures include inadequate design, improper construction and maintenance, extreme weather events, and natural disasters. When a tailings dam is damaged, breaches occur, or leaks develop, large volumes of tailings and process wastewater can be rapidly released, leading to severe contamination and ecological damage to surrounding soils, rivers, lakes, and even residential areas, while also posing immediate threats to human safety. To prevent and mitigate tailings dam accidents and to maximize protection of the environment and public safety, safety monitoring of tailings dams has garnered widespread attention and is now being implemented. By continuously monitoring key parameters such as dam structural stability, hydrological and water-quality conditions, deformation and displacement, and groundwater seepage, it is possible to detect anomalies early and take timely corrective and remedial actions. Analysis and interpretation of monitoring data enable engineers to assess the safety status of the tailings dam and to develop appropriate management and maintenance plans.
