Monitoring Principles
Based on the analysis of time-series InSAR data, buildings with abnormal deformations are automatically screened in a large urban area and classified into abnormal deformation classes.

Monitoring Principles
This system adopts BeiDou automated monitoring method to monitor the surface displacement of the monitoring area for automated deformation monitoring, and its working principle is as follows: each BeiDou monitoring point and reference point receiver receives BeiDou signals in real time and sends them to the control center in real time through the data communication network, and the BeiDou data processing software of the server of the control center decodes the three-dimensional coordinates of each monitoring point, and the data analysis module acquires the three-dimensional coordinates of each monitoring point and compares them with the initial coordinates to obtain the amount of change of the monitoring point. The data analysis module acquires the three-dimensional coordinates of each monitoring point and compares them with the initial coordinates to obtain the amount of change of the monitoring point, and at the same time, the analysis software alarms according to the pre-set warning value.

The technical parameters are as follows

Observation parameters
BDS: B1, B2, B3
GPS: L1 C, L2 P, L2 C, L5
GLONASS: L1 C/A, L2 C/A, L5
positioning accuracy
Level 2.5mm+1ppm RMS
Vertical 5mm+1ppm RMS

Monitoring Principles
The static level utilizes the principle of connecting fluids, and the liquid level of multiple reservoirs connected together by connecting tubes is always at the same level. By measuring the height of the liquid level of the non-functional reservoirs, the relative difference in the settling of each static level can be calculated.

The technical parameters are as follows

Measuring range: 400/1000/2000mm
Measurement accuracy: ≤0.1F.S.
Resolution: 0.01%F.S.
Operating mode: answering type
Supply voltage: 12VDC
Working Temperature: -20℃~50℃

Monitoring Principles
Seam gauge is installed on the surface of the building to measure the degree of opening and closing (deformation) of expansion joints or peripheral joints of the structure, and can be synchronized to measure the temperature of the buried point. With the addition of supporting accessories can be composed of bedrock displacement meter, surface crack meter, multi-point displacement meter and other deformation measurement instruments.

The technical parameters are as follows
- Displacement range: 20, 50, 100, 200mm (optional according to the actual situation)
- Sensitivity: ≤0.08mm
- Fitting accuracy: ≈ 0.5%F.
- Working temperature: -40~+85℃
- Water pressure resistance: > 1MPa

Monitoring Principles
Rainfall automated monitoring using tipping bucket rain gauge sensor for monitoring. Rainwater is collected by the water receiver - through the water inlet valve - into the water storage room - the water level rises - the float rises - the sensor reads the data - the microcomputer control circuit output passive pulse.

The technical parameters are as follows

Rainbow caliber: 200±0.6mm
Resolution: 2mm;
Rain intensity range: 01 to 4mm/min (Allowed to pass the maximum rain intensity of 8mm/min);
Measurement accuracy: ≤±4%
Working environment: temperature: -10 ~ +50 ℃, the relative humidity of the air is unlimited
BER: less than 10-4
Reliability index: MTBF ≥25000 hours
The rain gauge has a good ability to adapt to outdoor working conditions and should be protected against rust, corrosion, blocking and insects.

Monitoring Principles
Dangerous houses to establish video surveillance, dangerous houses in the region "no dead angle, full coverage" supervision, once the risk is found, can be linked with the higher part of the platform, timely verification and monitoring of the housing situation, and resolutely put an end to the occurrence of safety accidents.
