Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air detection, in particular to an air detection method and system. BACKGROUND

[0002] Air detection refers to a process of collecting and analyzing air samples by professional technical means to determine the types and concentrations of pollutants therein and to judge whether they meet relevant air quality standards.

[0003] After a room is decorated, the decoration materials and furniture will release indoor air pollutants, and long-term exposure to excessive pollutants can easily harm the body. In order to investigate potential health risks in indoor air, air detection of the room is generally needed. When air detection of the room is performed, a detection personnel generally determines sampling points according to the area of the room, and uses professional equipment (such as an air sampler) to collect air samples at the sampling points, and then sends the samples to a laboratory, analyzes the pollutant concentration by using professional instruments such as a gas chromatograph and a spectrophotometer, and thus detects the air.

[0004] When air detection of a room is performed, the detection personnel determines sampling points according to the area of the room, and then detects the air. If the detection personnel does not strictly distribute the points according to the area or the sampling points are close to local high-concentration areas such as door and window gaps and furniture gaps, the samples may not represent the overall air quality of the room, and thus air detection may have deviations.

[0032] The sampling device specification refers to the technical parameters of the device used to collect air samples. The sampling device specification includes sampling unit area value, sampling flow, sampling accuracy, etc. The sampling device specification is pre-selected and set by the detection personnel.

[0034] The space area value refers to the total area value of the internal space of the house building. The space layout refers to the layout of the rooms, doors, windows, ventilation openings, etc. inside the house building. The space placement refers to the type and location of furniture, decorations, and other items placed inside the house building.

[0037] The area sampling number refers to the number of air sample collection points that need to be arranged in the detection house according to the total area of the internal space of the house building.

[0038] The sampling unit area value is retrieved through the sampling device specification, and the quotient between the space area value and the sampling unit area value is calculated. The rounded calculation result is used as the area sampling number, which facilitates subsequent use.

[0048] The number corresponding to the single room range is counted, and the counting result is used as the room number. Then, the single room area value and the room center position points of the single room are calculated. When the area sampling number is consistent with the room number, the room center position points of each room are used as the single room position points.

[0049] When the area sampling number is not consistent with the room number, the single room area values are sorted from large to small. If the area sampling number is less than the room number, the room center position points of the rooms corresponding to the first area sampling number in the sorting result are selected as the single room position points. If the area sampling number is greater than the room number, the difference between the area sampling number and the room number is calculated as the excess sampling number, and the single room range corresponding to the first excess sampling number in the sorting result is selected as the excess placement range.

[0086] The comprehensive adjustment value and the comprehensive reverse information are combined to obtain the reverse vector value, and the reverse vector value is taken as the single adjustment vector value, improving the accuracy of the obtained single adjustment vector value.

[0087] S4536: Determine the room reference direction information based on the single room range.

[0088] The room reference direction information refers to reference direction information determined according to the room shape.

[0089] The single room shape is called by the single room range. When the single room shape is a regular shape, the direction of the longest side length or the direction of the central axis is directly used as the room reference direction information. When the single room shape is an irregular shape, the direction of the longest diagonal line in the single room shape is used as the room reference direction information, thereby facilitating subsequent use.

[0090] S4537: Generate the reference selection vector value according to the door window distance vector value, the ventilation opening distance vector value, and the room reference direction information, and use the reference selection vector value as the single adjustment vector value.

[0093] In order to further ensure the rationality of the reference selection vector value, it is necessary to make a further separate analysis and calculation on the reference selection vector value. The specific steps are as follows.

[0100] S45373: When the door window deviation angle value and the air vent deviation angle value are less than the preset deviation reference angle value, the larger value of the door window deviation angle value and the air vent deviation angle value is selected as the selected angle value, and the door window distance vector value or the air vent distance vector value corresponding to the selected angle value is taken as the selected distance vector value.

[0101] The deviation reference angle value refers to the maximum angle value corresponding to the door window or the air vent that is not easy to produce interference. The deviation reference angle value is set by the detection personnel according to the demand in advance.
