Whether the air quality is good or not, a very important indicator is to look at the particulate matter and content in the air. So do you know how the monitoring department monitors microparticles and aerosols in the air? The monitoring department will use a professional equipment called aerosol lidar to monitor and analyze particulate matter and aerosols in the air.

Aerosol lidar application scenarios

 

So what is aerosol lidar? It is based on the principle of atmospheric laser telemetry, which realizes the detection of the physical characteristics of atmospheric aerosols (particulate matter, sand and dust, etc.), can continuously monitor the distribution of atmospheric aerosols, and analyze the composition structure and temporal and spatial evolution of aerosols. At the same time, lidar can monitor the diffusion law of environmental pollutants above cities such as industrial smoke and dust emissions, and monitor weather processes such as haze and sandstorms. It is an important means and tool for atmospheric environmental monitoring and atmospheric scientific research.

 

At present, in aerosol lidar systems, a large number of connectors are used to provide functional and technical interconnection support. However, because the aerosol lidar is placed outdoors and limited by the particularity of the service conditions, the current connection technology solutions and products of aerosol lidar are mostly selected for industrial waterproof connectors with more guaranteed tolerance and adaptability.

CNLINKO industrial connector for aerosol lidar

 

CNLINKO, as a professional and mature industrial connector brand manufacturer, has had many successful cases in the field of aerosol lidar in recent years. Here to share the connection technology application of CNLINKO in the aerosol lidar application field.

 

In the aerosol lidar product of a certain manufacturer, the main part of the lidar is powered by CNLINKO's DH20-3 core power connector; the lidar device has a variety of built-in sensors that can monitor the laser status, ambient temperature and humidity in real time , UPS power, system status, fault alarm and other functions. Once the signal returned by the sensor shows abnormality, the alarm reminder function will be activated, and for some faults, the remote fault diagnosis and self-repair function will be activated. Among them, CNLINKO's DH24 is used. -RJ45 signal sensor; Lidar analyzes the distribution of aerosols through laser emission and echo, and then collects aerosol environmental data in the monitored area through the data acquisition system. These data can be returned to the data with the help of CNLINKO's DH24-USB data connector. The leaflet machine realizes data storage. If it is connected to the Internet, it can also realize real-time data upload for real-time access and analysis by scientific researchers and inspectors.

CNLINKO's connection solutions and products for aerosol lidar (partial)

 

 

CNLINKO's industrial waterproof connector can meet the professional connection technical requirements of aerosol lidar, and has the following characteristics:

 

1. Waterproof and dustproof, no fear of bad weather such as rain and fog

 

      The main part of the aerosol lidar detection is in an outdoor environment, and severe weather such as rain and fog poses a huge threat to the reliability of the lidar. CNLINKO's waterproof connector adopts an integrated shell with multiple waterproof rings inside, which can reach IP67 waterproof level (or above) in the connected state, effectively avoiding the intrusion of foreign objects such as water, liquid, dust, etc., and ensuring the reliability of the aerosol lidar connector Sex and safety;

 

2. The locked state is firm and does not fall off

 

      During the detection process, the aerosol lidar detection body rotates the body and emits lasers in different directions. In addition, the lidar device installed on a moving vehicle is subject to vibration and turbulence. Therefore, anti-vibration and anti-dropping are rigid requirements. The above-mentioned industrial connector products of CNLINKO have high-strength structural design and snap spring locking structure design. The connection is firm and reliable. Under vibration and other conditions, there will be no loosening, falling off, or poor contact;

 

3. High and low temperature impact resistance

 

The main part of the aerosol lidar detection is outdoors, and the external environment such as high temperature exposure in summer and freezing and cold in winter is normal, and the resistance of the connector under high and low temperatures is very high. CNLINKO's connectors are manufactured according to industrial standards to meet the wide range of high and low temperature applications: -40℃—+85℃, which can meet the high and low temperature tolerance requirements of aerosol lidar connectors in applications;

 

4. High-speed signal transmission without delay

High-speed, fidelity, and no delay of signal transmission are important in signal transmission such as monitoring laser status, ambient temperature and humidity, and UPS power. CNLINKO's waterproof aviation plug socket adopts anti-interference shielding structure design, has electromagnetic compatibility, helps reduce crosstalk and maintain signal integrity, and can transmit signals at high speed;

 

5. Powerful data transmission performance

CNLINKO's USB interface data connector, high-conductivity material, stable and reliable contact points, and supplemented by high-quality wires, can achieve high-speed transmission of large-capacity collected data, reliable data without loss, completeness and other requirements.

 

 

At present, environmental monitoring stations and scientific research institutions in various places are equipped with monitoring equipment such as aerosol lidar to monitor and research the quality of the urban atmospheric environment, to fully grasp the distribution of atmospheric pollutants, and to timely find and accurately locate the source of pollution , The implementation of all-weather supervision and monitoring work is conducive to the monitoring of environmental changes and pollution sources, accurate law enforcement, effective maintenance of environmental safety, and the construction of livable cities.

 

Protecting the environment and contributing to environmental protection has always been one of CNLINKO's persistent goals. For this reason, CNLINKO gives full play to the core advantages of the company, and cooperates with domestic environmental protection companies such as aerosol lidar and other lidar equipment enterprises to better adapt to harsh service scenarios, more innovative, high-performance, and highly reliable industrial waterproof connector products and The plan supports environmental protection enterprises, serves environmental protection undertakings, and contributes the strength and responsibility of the enterprise to build a better home and create a more livable living environment.
