Surface displacement monitoring system

1.Surface displacement monitoring system product introduction

Surface displacement monitoring system is a displacement monitoring device for real-time monitoring of surface subsidence, settlement and ground displacement.The surface displacement monitoring system is a millimeter-level displacement monitoring product that uses differential RTK technology. It can be widely used in engineering fields such as dam safety monitoring, bridge health detection, and landslide warning. The product has high precision, high stability, and real-time data transmission capabilities, and can accurately monitor the tiny displacement changes of the target in various complex environments. The surface displacement monitoring system is simple to operate and easy to install. It can be remotely monitored and analyzed for data, providing strong protection for engineering safety. In addition, its powerful data processing capabilities and compatibility allow the product to be easily integrated into various monitoring systems to achieve data sharing and integration, providing a strong guarantee for engineering safety monitoring.

Provide comprehensive and efficient solutions.

3. Surface displacement monitoring system product installation

Installation requirements:

1. There should be no tall buildings around either the base station or the measuring station. If this is unavoidable, they should be at least 20 meters away.

2. The recommended distance between the base station and the measuring station (baseline distance) is less than 500 meters, and the maximum distance is no more than 2 km. They should be installed at the same altitude as much as possible. Too large a distance will cause the longitude to decrease.

3. The base station and the measuring station should be visible to each other as much as possible. If they cannot be completely visible, high walls, buildings, etc. should be avoided.

4. Ensure that the measuring antenna is the highest point within 20 meters.

5. The installation base should be firm to avoid loss of accuracy due to wind.

6. The height of the data transmission antenna and lora antenna cannot be higher than the measurement antenna, and should be kept as far away from the measurement antenna as possible. To ensure the accuracy of subsequent measurements, you can also contact the company's after-sales video guidance for specific installation matters.
