Problems solved by technology

[0003] In order to solve the deficiencies in the prior art, the present invention provides a sensor, a monitoring station based on the sensor and a monitoring method of the monitoring station, which can continuously and automatically measure atmospheric particulate matter with low measurement cost, can measure the concentration of atmospheric particulate matter in real time, and are convenient for maintenance , and overcome the shortcomings of the general light scattering method, such as poor accuracy, short life, and unsuitable for outdoor measurement. It can also calibrate the adverse effects of the external environment and humidity on the detection results, increase the accuracy of monitoring, and form a monitoring station. The monitoring network can obtain more detailed monitoring data than the national control station, and fill in the monitoring shortage of the national control station. People can determine the air quality level based on the monitoring data of the sensors used for atmospheric particulate matter monitoring near where they live, helping people determine Protective measures for going out to reduce the increase of atmospheric particles in the local air and the harm to the people in the area

Abstract

The invention discloses a sensor, a monitoring station based on the sensor and a monitoring method of the monitoring station. The monitoring station comprises a cloud server device and a plurality of sensors and also comprises temperature and humidity sensors corresponding to the sensors both in number and position, wherein the cloud server device is in signal connection with atmosphere particle monitoring sensors and national-level monitoring stations. The sensor, the monitoring station and the monitoring method have the benefits that atmospheric particulates are continuously and automatically measured, the measurement cost is low, the concentration of atmospheric particulates can be measured in real time, maintenance is convenient, and defects that an ordinary light scattering method is poor in accuracy, short in service life and not suitable for outdoor measurement and the like are overcome.

Description

technical field [0001] The invention mainly relates to the field of atmospheric particle detection, in particular to a sensor, a monitoring station based on the sensor and a monitoring method for the monitoring station. Background technique [0002] At present, the main means of detection of atmospheric particulate matter are: gravimetric method, micro-oscillating balance method, β-ray method and light scattering method. Low, about 1 hour for one piece of data, expensive (generally 100,000 to hundreds of thousands of sets), and complicated maintenance. These characteristics make these mainstream methods inconvenient for grid detection of atmospheric particulate matter with high-density coverage, and cannot meet the air pollution detection in my country, and gradually increase the grid development trend of monitoring density. The low-cost light scattering method currently has problems such as insufficient measurement accuracy, short lifespan, and is easily affected by the ex...
