Wuhan Zhongdi Hengda - Pile Body Internal Force Monitoring System
System Introduction
The pile body internal force monitoring system is mainly used for real-time automated monitoring of the internal force of anti-sliding pile bodies, and is applicable to application fields such as foundation pits, national land geological disasters, mine geological disasters, and water conservancy and hydropower monitoring. The monitoring system adopts an integrated design, integrating the sensors required for pile body internal force monitoring, data acquisition, data transmission, solar power supply, upright brackets, etc., making field installation operations simple and convenient.

3. Monitoring System Configuration
Serial Number | Name | Description |
1 | Sensor | Rebar Stress Gauge, Earth Pressure Cell |
2 | Vibrating Wire Signal Collector | Used for data acquisition and storage |
3 | GPRS Antenna | Used for data transmission |
4 | Solar Panel | 100W (can be adjusted according to actual conditions, or can be replaced with mains power supply) |
5 | Storage Battery | 65Ah maintenance-free battery (can be adjusted according to actual conditions) |
6 | Charge Controller | Protects the storage battery and prevents overcharging; 12V/24V 20A |
7 | Chassis | Houses internal equipment and provides protection |
8 | Integrated Installation Bracket | Stainless steel galvanized steel pipe, 2 meters (can be adjusted according to actual conditions) |
9 | Cloud Platform | Data display, export, and early warning |
4. Functional Features
1) Supports sending data in different protocol formats to 3 or more addresses;
2) Auto-recovery after disconnection, and automatically re-sends unsuccessfully transmitted data when the network is restored;
3) Optional synchronous monitoring of storage battery/solar voltage, charge and discharge information, temperature and humidity, signal strength, location information, etc.;
4) Supports multiple working modes: sleep mode, online mode, early warning mode;
5) Has a threshold trigger function, and automatically reports immediately when monitoring data exceeds the threshold;
6) Can store data for more than 2 years, with the function of automatically overwriting old data in a cycle;
7) Remote control, online upgrade of hardware programs;
8) By installing multiple rebar stress gauges or embedded strain gauges inside slope anti-sliding piles (retaining walls, lattice beams), the monitoring system can be used to automatically measure the internal force of the structure for a long time;
9) By installing multiple earth pressure cells on the slope-facing side of slope anti-sliding piles (retaining walls), the monitoring system can be used to automatically measure the lateral earth pressure of the structure for a long time;
10) The equipment has strong corrosion resistance and rust resistance, and factors such as temperature, freeze-thaw, rain, dust, and strong wind will not affect the normal operation of the equipment system.
