Cortex-M3 processor.The machine adopts two kinds of display modes mutually to supplement in the application, with satisfied different demand, thus provides reference more to user.The machine has superior performance, and reliability is high, and cost is low, the feature easily promoted.
Description
Technical field
The utility model relates to air detection equipment, specifically a kind of PM2.5 measurement mechanism.
Background technology
In recent years, people more and more pay close attention to air quality, environmental problem.In the face of haze, national government is put into effect a series of policy and is administered air pollution problems inherent under overall situation.And also emerge in large numbers on the market and the PM2.5 measurement mechanism of polymorphic display can understand the air quality of environment for people in a large number.But great majority the PM2.5 measurement mechanism of polymorphic display can only possess single Presentation Function in a large number, and do not possess the characteristic of polymorphic display, the utility model provides a kind of scheme of PM2.5 concentration value of polymorphic display.
Above-mentioned discussion content object be to reader introduce may to below by the various aspects of technology relevant for the various aspects of the present utility model be described and/or advocate, believe that this discussion content contributes to for reader with background's information, to be conducive to understanding various aspects of the present utility model better, therefore, should be appreciated that it is discuss to read these with this angle, instead of admit prior art.
Utility model content
The purpose of this utility model is to provide a kind of superior performance, and what reliability was high can the PM2.5 measurement mechanism of polymorphic display.The machine can testing environment PM2.5 concentration value and by liquid crystal display and LED, these two kinds of modes show.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of can the PM2.5 measurement mechanism of polymorphic display, include cabinet and establish dust sensor, controller and display screen in the chassis, described dust sensor sends air detection information to controller, and the detected value of dust sensor is sent to display screen display by controller; Also comprise the air detection result pilot lamp be electrically connected with described controller, described air detection result pilot lamp, adopts multiple color LED lamp, the color that different PM2.5 concentration correspondence displays is different.
Further, described display screen adopts TFTLCD liquid crystal display.
Further, described controller adopts ARM Cortex-M3 processor.
Further, described color LED lamp is arranged on the side of cabinet top cover.
Useful effect of the present utility model: the machine adopts two kinds of display modes mutually to supplement in the application, with satisfied different demand, thus provides reference more to user.The machine has superior performance, and reliability is high, and cost is low, the feature easily promoted.
Accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing does not form any restriction of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the following drawings.
Fig. 1 is structural representation of the present utility model.
In figure: 1, cabinet; 2, dust sensor; 3, controller; 4, display screen; 5, air detection result pilot lamp.
Embodiment
The technical solution of the utility model is understood better in order to make those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, it should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As shown in Figure 1, can the PM2.5 measurement mechanism of polymorphic display, include cabinet 1 and be located at dust sensor 2, controller 3, display screen 4 and the air detection result pilot lamp 5 in cabinet 1, described dust sensor 2 sends air detection information to controller 3, and controller 3 sends the detected value of dust sensor 2 to display screen 4 and shows.Described display screen adopts TFTLCD liquid crystal display, and described controller adopts ARM Cortex-M3 processor.
Described air detection result pilot lamp 5, adopt multiple color LED lamp, color LED lamp is arranged on the side of cabinet top cover, is symmetric.The instruction that color LED lamp receiving control system sends, the color that different PM2.5 concentration correspondence displays is different.Specifically, color LED lamp display PM2.5 concentration adopts grade display mode, and air quality is divided into four grades: excellent, good, in, poor.Controller controls LED by algorithm and shows white respectively, green, blue, red four kinds of colors.To reach the object of reminding user current air mass situation.
The machine accurately shows PM2.5 concentration by adopting TFTLCD liquid crystal display, utilizes LED hierarchical display PM2.5 concentration, therefore has practical strong feature; Detect filter paper color by color mark sensor and carry out automatic paper-changing function to control steering wheel rotation.
Set forth a lot of detail in description above so that fully understand the utility model, but the utility model can also adopt other to be different from other modes described here and implement, and therefore, can not be interpreted as the restriction to the utility model protection domain.
