The air quality monitoring meter can monitor the air quality in the classroom and has the characteristics of intuition and precision.
Description
Technical field
The utility model relates to a kind of classroom and uses the air quality monitoring table, belongs to electronic technology field.
Background technology
The classroom is personnel's places with dense, owing to the metabolic carbon dioxide that discharges of human body, volatile organic matter etc., can cause air dirt in the classroom.CO in the air of classroom
2The survey showed that to the influence of the mental work capacity of student for concentration, along with air CO
2Concentration increases, and mental work capacity obviously descends, and the air dirt is to cause that the student is tired, very important factor of reduction results of learning.Air quality in current China classroom allows of no optimist, and resh air requirement is seriously not enough, and gas concentration lwevel exceeds standard more.In the air of health, learn, the student can better remember that institute gains knowledge, and teacher also still less calls in sick.Also do not see to the air quality monitoring instrument in the classroom at present.The utility model provides a kind of instrument that can monitor and point out air quality in the classroom.
The utility model content
The purpose of the utility model provides a kind of classroom and uses the air quality monitoring table, satisfies the monitoring demand of people to air quality in the classroom.
The technical scheme that the utility model adopted is:
The air quality monitoring table is used in a kind of classroom, comprises air borne sensor and monitoring form main body; Said monitoring form main body comprises circuit control section, display and o controller; Described air borne sensor comprises one or more in carbon dioxide sensor, formaldehyde sensor, VOC sensor, particulate matter sensors, the water vapor sensor, and various sensors use one or more than one, various sensors are installed in the classroom; Said circuit control section is collected the monitor signal of air borne sensor, flows to said display and said o controller after the processing, and said display is used to show each monitoring index; Said o controller is used to control VMC or air cleaning system.
The air quality monitoring table is used in described classroom, and said air borne sensor and said monitoring form main body become one.
The air quality monitoring table is used in described classroom, said air borne sensor and the partial installation of said monitoring form main body.
The air quality monitoring table is used in said classroom, can in display, point out according to monitoring result, and reminding method has variable color backlight, flicker, literal prompting etc.
The utility model can be monitored the air quality in the classroom, has characteristics directly perceived, accurate.
Description of drawings
Fig. 1 is the structural representation of embodiment 1 classroom with the air quality monitoring table;
Fig. 2 is the structural representations of embodiment 2 classrooms with the air quality monitoring table.
Embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
Embodiment 1
Like Fig. 1, air borne sensor adopts single carbon dioxide sensor, and the monitoring form main body has: attaching plug, circuit control section and display.Wherein said carbon dioxide sensor is integrated in the monitoring form body interior; Said display is a liquid crystal display; Said attaching plug can connect the civilian power supply of 220V; Said circuit control section receives the signal that said carbon dioxide sensor transmits, and this signal transition is become the gas concentration lwevel value, and concentration value calculates the pure and fresh index of representing degree with fresh air in the current classroom thus.Said circuit control section is passed to said display with gas concentration lwevel value and pure and fresh index, is shown by said display.
Embodiment 2
Like Fig. 2; Air borne sensor comprises carbon dioxide sensor 1, carbon dioxide sensor 2 and particulate matter sensors; The monitoring form main body has: attaching plug, circuit control section, display and o controller; Wherein said carbon dioxide sensor 1 is installed on the ceiling of classroom middle front part, and carbon dioxide sensor 2 is installed on the ceiling of postmedian.Said particulate matter sensors is installed in anterior top, dais, classroom, mainly is used for surveying the chalk dust equal size.Said carbon dioxide sensor 1, carbon dioxide sensor 2 and particulate matter sensors pass to said circuit control section through data line with signal; Said circuit control section is separately converted to gas concentration lwevel value 1, gas concentration lwevel value 2 and particle concentration value with the signal of said carbon dioxide sensor 1, carbon dioxide sensor 2 and particulate matter sensors, and said gas concentration lwevel value 1, gas concentration lwevel value 2 and particle concentration value are carried out the pure and fresh index that full scale segmentation and weighted mean are handled degree with fresh air in the current classroom of reflection that obtains.Said circuit control section sends to said display and said o controller with said gas concentration lwevel value, gas concentration lwevel value 2 and particle concentration value and said pure and fresh index.Said display is a LED display, shows said gas concentration lwevel value 1, gas concentration lwevel value 2, particle concentration value and pure and fresh index.Said controller can be used to control the keying or the rate of venting of VMC.Said attaching plug directly connects the civilian power supply of 220V.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model accompanying claims according to above-mentioned explanation.
Claims (3)
