Design plan for monitoring the deformation and settlement of signal towers
Design principles of the monitoring system: 1. Reliability; 2. Advancement; 3. Scalability; 4. High cost-performance ratio;
The main technologies and products of the system are mature, stable, and practical, fully meeting the needs of actual applications, technology development, and information management. It ensures precise monitoring under harsh weather conditions. In the event of a sudden power outage, the system can operate continuously 24/7.
Network design ensures the reliability of network operation, allowing the entire system to continue functioning even if an unexpected event occurs at any node. Sensors are calibrated by national metrology departments and have relevant measurement certificates. Mature self-developed core technologies are used, and equipment selection should consider brands with good market technical support, strong service capabilities, stable equipment performance, and good scalability, ensuring the design has stability and foresight. The system construction should not blindly pursue high configurations but should design a system structure with good scalability while ensuring reliability. Products with good scalability and upgrade capabilities should be selected, and the system structure should be modular to ensure the overall scalability of the system.
1. Monitoring scope:
1. Structural settlement monitoring 2. Inclination and horizontal displacement monitoring
2. Monitoring content:
Using sensors, data acquisition devices, and wireless transmission systems for real-time, comprehensive, wireless, and automated monitoring of the overall settlement, differential settlement, and inclination of the signal tower.
3. System composition:
The system consists of sensors (static level gauges, inclination sensors), data acquisition devices, wireless signal transmission devices, central signal receiving and processing devices, computer rooms, and software systems. The system establishes an open data interface, allowing access through dedicated lines or the public internet under bandwidth conditions, supporting remote expert consultations.
4. System functions:
On-site data is sent to the monitoring center PC via a wireless GPRS transmitter, and the software automatically converts the measurement data, directly outputting the monitored physical quantities for data transmission via the internet or internal local area network, completing the collection and monitoring of sensor data. The software can set upper limit alarm commands, and mobile SMS alarms can provide real-time control. Data collection and monitoring can be performed via PC connected to the network.
5. Sensor parameters:
Inclination sensor (inclination and horizontal displacement monitoring), accuracy: 0.3-0.001° selectable, acquisition frequency: 100Hz; static level gauge (structural settlement monitoring), accuracy: ±0.1MM, range: 0.2-2000MM; communication methods: GPRS, Bluetooth, ZigBee (optional); transmission distances: GPRS (3G4G network), Bluetooth <10M, ZigBee <250M customizable.
Sensor type: small size, low power consumption, using hydraulic static level gauges, customized inclination meters for tower monitoring, with an integrated 24-bit ARM chip system, resolution of 4 seconds, and response frequency up to 100HZ. Power supply: optional mains power, solar energy, lithium battery; power consumption: less than 1.5W; input voltage: DC9-36V; operating temperature range: -40℃ to +85℃;
Forecast and early warning:
Real-time analysis and interpretation of various monitoring data, providing single or multiple comparison alarm functions, and establishing a mechanism for elimination during the handling of forecast and early warning situations, ensuring timely processing of forecasts and warnings.
System management:
Provides good management support for the information release platform, making the information release platform more flexible.
