Dangerous Houses Monitoring

     System Advantages    

     Monitoring elements    

  • 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

    • 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)

    • 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);

    • 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.
