Embodiment Construction

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] The monitoring system consists of a group of nodes, recorded as NODE={Node 1 ,Node 2 ,...,Node n}, these nodes contain a cluster head node, and the rest are ordinary nodes; these nodes follow the set time slot (t 0 ,t 1 ,...,t m ) to monitor air quality.

[0033] For any Node i Contains 8 modules, which are sensor group, data cleaning module, DHPFF (Distributed Hybridparticle / Finite impulse response Filter) filter module, Kalman filter...

The sensor group is connected with the data cleaning module, the data cleaning module is connected with the DHPFF filtering module and the Kalman filtering module, the DHPFF filtering module is connected with the Kalman filtering module and the parameter library, the Kalman filtering module is connected with the cognitive management module and the parameter library, and the cognitive management module is connected with the transceiver module. The invention is used for solving the problem of inaccurate measurement caused by factors such as air humidity, air pressure and wind speed of a single sensor.

Description

technical field [0001] The invention belongs to the field of air pollution monitoring; in particular, it relates to an air pollutant concentration monitoring device, a monitoring system and a monitoring method based on joint filtering. Background technique [0002] With the rapid development of my country's economy, people's living standards have been greatly improved, but it has also brought about problems such as air pollution. Factory exhaust, vehicle exhaust, and coal-fired heating have led to more and more air pollution. Air pollution not only affects It not only affects people's production and life, but also has a great impact on people's health. In recent years, the air quality in China has been far below the recommended standards of the World Health Organization (WHO). Fine particle pollution has become an extreme environmental and social problem that has a significant impact on human health and the national economy. Facing the serious problem of fine particle pollut...
