Embodiment 1

[0045] refer to figure 1 , the first embodiment of the present invention provides an online monitoring method for the concentration of negative oxygen ions in the air, comprising:

[0046] Step S10, collecting current negative oxygen ion measurement data;

[0047]As mentioned above, it needs to be understood that air is a mixture composed of various molecules. Due to the influence of natural cosmic rays, ultraviolet rays, soil and air radiation, some molecules in the air release electrons and anions. Most of the free electrons produced by the ionization of air molecules under the action of high pressure or strong rays are obtained by oxygen. Therefore, negative air ions are often collectively referred to as "negative oxygen ions". Negative oxygen ions are negatively charged, colorless and odorless. According to medical data, air negative oxygen ions are known as vitamins in the air, which can degrade and neutralize harmful gases in the air. Regulate human physiological funct...

Embodiment 2

[0059] refer to figure 2 , the second embodiment of the present invention provides an online monitoring method for the concentration of negative oxygen ions in the air, based on the above figure 2 In the first embodiment shown, the "confirming the mode in the current negative oxygen ion measurement data, and calculating the current negative oxygen ion concentration according to the mode" includes:

[0060] Step S21, judging whether the number of occurrences of the mode in the current negative oxygen ion measurement data exceeds a first threshold;

[0061] After the current negative oxygen ion measurement data is collected, the mode evaluation algorithm is performed on the current negative oxygen ion measurement data, that is, whether the number of occurrences of the mode in the current negative oxygen ion measurement data exceeds The first threshold is judged.

[0062] As mentioned above, the number of occurrences of the mode is the number of times the mode appears in one ...

Embodiment 3

[0086] refer to image 3 , the third embodiment of the present invention provides an online monitoring method for the concentration of negative oxygen ions in the air, based on the above figure 2 In the third embodiment shown, after the "judging whether the number of occurrences of the mode in the current negative oxygen ion measurement data exceeds the first threshold", it also includes:

[0087] Step S24, if the number of occurrences of the mode in the current negative oxygen ion measurement data does not exceed the first threshold, then use the average value of all the current negative oxygen ion measurement data as the current negative oxygen ion concentration.

[0088] As mentioned above, if the number of occurrences of the mode does not exceed the first threshold, the average value of all the collected current negative oxygen ion measurement data is used as the current negative oxygen ion concentration. In this embodiment, the first threshold may be 3.

[0089] For e...

Abstract

The invention provides an online monitoring method for air negative oxygen ion concentration and device, wherein the method comprises the following steps: collecting current negative oxygen ion concentration measurement data; determining a mode in the current negative oxygen ion concentration measurement data and calculating the current negative oxygen ion concentration according to the mode. According to the invention, by obtaining the current negative oxygen ion concentration according to a mode estimation algorithm for the collected collecting current negative oxygen ion concentration measurement data, more accurate and more steady current negative oxygen ion concentration data can be obtained in the conditions that the collected data are usually unsteady and numerical value transitionconstantly occurs, and therefore, the reliability of the data is improved, an air quality monitoring worker can accurately and effectively master the current air quality condition in real time, and convenience is brought for the air quality monitoring work.

Description

technical field [0001] The invention relates to the technical field of air quality monitoring, in particular to an online monitoring method and device for the concentration of negative oxygen ions in the air. Background technique [0002] Negative oxygen ions are known as "air vitamins". High concentrations of negative oxygen ions are beneficial to physical and mental health. Therefore, the concentration of negative oxygen ions in the air is a positive indicator for judging the freshness of the air and the living environment. Many tourist attractions, such as valleys, forests, seashores, etc., play the "negative oxygen ion" brand, and the high concentration of negative oxygen ions has become the business card of many scenic spots. Therefore, the monitoring of the concentration of negative oxygen ions in the air has broad market prospects. [0003] In the environmental evaluation system, the concentration of negative oxygen ions in the air has been listed as an important par...
