Description

Wall-hung type indoor air quality monitoring device

Technical field

A kind of indoor air quality monitoring instrument of this utility model design, is suspended on the place walls such as gymnasium, gymnasium, dancing room, infant room, factory floor, for the high accurate indoor air quality monitoring instrument of monitoring in 24 hours particularly to one.

Background technology

Along with China's expanding economy, the contradiction of economic development and environmental pollution highlights day by day, and the situation of nationwide severe haze is of common occurrence, and the case that the cough brought out because of haze, asthma are even suffered a shock is appeared in the newspapers repeatly.On the other hand, owing to the restriction of material technology or the virtue of material maker are uneven, formaldehyde after new house finishing, benzene, ammonia and TVOC pollute situation about exceeding standard and get married normal potluck, even fit up the house after for many years and also often occur that harmful gas exceeds standard.The places such as gymnasium, gymnasium, dancing room, infant room, factory floor are relatively big due to quantity of motion, are more prone to be subject to the infringement of the harmful substance such as PM2.5 and formaldehyde, and neonate is owing to having a low resistance, more fragile in face of the harmful substance such as PM2.5 and formaldehyde.

Summary of the invention

For above-mentioned ubiquitous Tough questions, this utility model provides a kind of based on ARM high-performance processor, the useful equipment hanging on wall monitoring upper 24 hour IAQ (indoor air quality).

This utility model solves the technical scheme of above-mentioned technical problem: a kind of wall-hung type indoor air quality monitoring device, and this device is made up of internal structure and shell, and internal structure is installed in the enclosure；Internal structure includes PM2.5 sensor assembly 1, formaldehyde sensor module 2, VOC sensor assembly 3, Temperature Humidity Sensor module 4, clock module 5, power module 6, WIFI module 7, voice module 8, quiet fan 9, main controller module 10, numeral method module 11；Wherein, PM2.5 sensor assembly 1, formaldehyde sensor module 2, VOC sensor assembly 3, Temperature Humidity Sensor module 4, clock module 5 are in parallel and connect to form groups of sensor；Groups of sensor, power module 6, WIFI module 7, voice module 8, numeral method module 11, being connected with main controller module 10 respectively, quiet fan 9 is connected with power module 6.

Shell is provided with draw-in groove and deck, and draw-in groove matches with deck and is movable part, and deck is fixed on body of wall by bolt or glue bond.

Described main controller module 10 adopts high-performance 32-bit super low-power consumption ARM microprocessor as master controller, by PM2.5 sensor, formaldehyde sensor, VOC sensor analogue signal change into digital signal, and through software filtering, optimization, calculate the real-time concentration of PM2.5, formaldehyde and TVOC.

Further, described wall-hung type indoor air quality monitoring instrument, by a quiet fan, promote air flowing, one side can, so that PM2.5 reading is more stable accurately, can promote to react rapider when formaldehyde and TVOC detection on the other hand.

Further, described wall-hung type indoor air quality monitoring instrument, using a power module is that direct current 5V and direct current 3.3V powers to monitor by civilian for 220V/50Hz Power convert.

Further, 32 described arm processors are STM32F103R8T6, and carry multiple 12 analog-digital converters inside it.

Further, air quality data can not only be sent to mobile phone and PC by described WIFI module, it is also possible to when air quality is not good enough, automatically turn on purification utensil air by WIFI module.

Further, the parameters such as Time of Day can be adjusted by mobile phone terminal application software, the parameter such as PM2.5 and formaldehyde is calibrated.

The beneficial effects of the utility model are: this utility model can not only remind people stop motion and other aggravating activitieses when haze is serious, it is prevented that because haze induces an illness；Also being able to remind resident family when the harmful substances such as indoor formaldehyde, benzene, ammonia exceed standard, window in time ventilation or unlatching purification utensil air, when being not easy to execute-in-place, monitor can automatically turn on depurator.

Adopting high-performance 32-bit arm processor as master controller, disposal ability is remarkably reinforced, and processing speed significantly improves, and circuit structure is simplified, and reliability and capacity of resisting disturbance get a promotion.
