Dam seepage pressure monitoring system

　　Dam seepage pressure monitoring systemThe system collects real-time pore water pressure data and accurately senses changes in the seepage field by deploying high-precision pressure gauges at key locations such as the dam body and foundation. After the data is automatically processed by the collection terminal, it is uploaded to the monitoring platform through a wireless communication module to generate a seepage pressure distribution map and dynamic curve. The system has built-in intelligent analysis algorithms that can automatically identify abnormal pressure fluctuations and trigger warnings immediately when the value exceeds the safety threshold.

　　Dam seepage pressure monitoring systemThe seepage monitoring system mainly consists of on-site detection equipment, remote monitoring equipment, and other components.

On site testing equipment: composed of measuring weirs, triangular weirs, etc., responsible for measuring the seepage flow data of the reservoir and monitoring the flow rate on site.

Remote monitoring equipment: i.e. remote monitoring terminal, responsible for collecting data information detected by on-site detection equipment and transmitting the on-site information to the monitoring center through wireless transmission.

Introduction

The water measuring weir adopts magnetostrictive sensors for liquid level measurement, which have the characteristics of high resolution, good stability, reliable performance, fast response speed, linear measurement, no wear and tear, and long working life. The water head on the weir is measured by a measuring weir, and the flow rate is calculated based on empirical formulas for weir channels (triangular weir, trapezoidal weir, rectangular weir, etc.).

Structure and Principle

The water measuring weir is composed of a magnetic rod, a floating ball, a measuring circuit, and a stainless steel casing. When the water level in the weir tank changes, it will drive the floating ball to produce a liquid level difference. The upper computer uses the current liquid level to subtract the calibrated base value to obtain the actual water level on the weir, and then calculates the flow rate based on the type of weir tank.
