GCG1000The series of dust detectors ensure data accuracy through multi-dimensional technology design, including:

1. Laser scattering core detection technology
Using the principle of laser irradiation, when particles pass through the detection area, the laser beam scatters with the particles. The device captures the intensity and distribution characteristics of scattered light signals through precision optical sensors, and uses a mathematical relationship model between scattered light intensity and particulate matter mass concentration to accurately invert them in the airPM2.5ThePM10andTSPReal time concentration values. This technology has high sensitivity and anti-interference ability, and can effectively distinguish particles of different sizes.

2. Structural design of anti pollution machinery
The movement adopts an open sensing probe structure and forms a stable airflow channel through fluid dynamics optimization design. This structure can ensure the smooth passage of the measured gas through the detection area and prevent large particles or dust from directly depositing on the surface of the optical component. Compared to a closed chamber design, an open structure significantly reduces measurement errors caused by pollutant adhesion, while avoiding particle breakage or secondary dust issues that may arise from traditional fan sampling.

3. Dynamic environment compensation algorithm
Built in intelligent temperature and humidity compensation module, capable of real-time monitoring of environmental temperature and humidity changes (working range:0℃~+40℃, humidity≤95%RH）. By establishing temperature and humidity-The concentration correction model automatically eliminates the influence of water vapor condensation or temperature fluctuations on laser scattering signals. For example, in high humidity environments such as underground coal mines (with relative humidity close to)95%RH）In the middle, it can still maintain±5%FSMeasurement accuracy.

4. Multi level signal calibration system
Implement full range calibration during the production process:

Zero point calibration: using a dust-free air reference environment

Range calibration: Use a standard particle size generator (such as0.3μmThe2.5μmThe10μmStandard particles)

5. Anti interference circuit design
The power module adoptsDC18VLow ripple power supply, operating current<50mAEffectively suppress electromagnetic interference. The signal processing unit integrates digital filtering algorithms, which can automatically identify and eliminate vibrations（≤5g）Impact（≤50m/s²）Waiting for mechanical interference and explosive gases such as methane concentration<5%）Chemical interference.

6. Real time self inspection and fault diagnosis
Each device24Automatically execute the optical path self-test program on an hourly basis, verifying the system response by emitting standard optical signals. When detecting light intensity attenuation exceeding15%Immediately trigger the sound and light alarm and output a fault code, prompting the user to clean the optical window or replace key components.
