Accompanying drawing explanation

The present invention can be further illustrated by the nonlimiting examples that accompanying drawing is given;

Fig. 1 is the structural representation of the embodiment of the present invention a kind of intelligent air quality monitoring device.

Detailed description of the invention

In order to make those skilled in the art that the present invention be may be better understood, below in conjunction with the accompanying drawings with embodiment to the technology of the present invention Scheme further illustrates.

As it is shown in figure 1, a kind of intelligent air quality monitoring device of the present invention, including temperature sensor, humidity sensor, oxygen Gas sensor, ammonia gas sensor, volatile organic matter sensor, dust sensor, central processing unit, LED, it is wirelessly transferred mould Block, air cleaning facility, main frame, server and mobile phone A PP, central processing unit is PIC18 series monolithic, temperature sensing Device and humidity sensor are physical sensors, and oxygen sensor is electrochemical sensor, and ammonia gas sensor and volatile organic matter pass Sensor is semiconductor chemical sensor, and dust sensor is the defeated of infrared diffusion sensor, temperature sensor and humidity sensor Go out end to be connected with the common I/O port of central processing unit, the outfan of oxygen sensor and ammonia gas sensor and the simulation of central processing unit Port connects, and the outfan of volatile organic matter sensor is connected with the IIC peripheral hardware of central processing unit, the output of dust sensor Holding the seizure with central processing unit to input IO to be connected, central processing unit includes A/D conversion, table look-up evaluation and data process, central authorities The input that the outfan of the common I/O port of processor, IIC peripheral hardware and seizure input IO processes with data is connected, and central authorities process The analog port outfan of device and A/D conversion, evaluation and the data of tabling look-up process and are sequentially connected with, and the outfan that data process divides two Branch road is connected with wireless transport module and LED respectively, and the outfan of wireless transport module is connected with the input of air cleaning facility, The outfan of wireless transport module and the input wired connection of the input wireless connections of main frame, the outfan of main frame and server, The outfan of server and the input wireless connections of mobile phone A PP.

In the present embodiment, after powering on, temperature sensor, humidity sensor, volatile organic matter sensor, dust sensor will The content information of temperature, humidity, volatile organic matter and dust in spatial environments passes to central processing unit in real time, and transmits Processing to data, the content of the oxygen in spatial environments and ammonia is processed by oxygen sensor and ammonia gas sensor by central authorities simultaneously The analog port of device passes to A/D conversion, it is achieved analogue signal is converted to digital signal, and the signal after conversion is by evaluation of tabling look-up Pass to after obtaining actual concentrations data data process, data process receive temperature, humidity, volatile organic matter, dust, It is analyzed after the content data of oxygen and ammonia and processes, then outputing signal to LED and show, when finding air quality Time abnormal, transmit a control signal by wireless transport module to air cleaning facility, make air cleaning facility switch open, Thus the air cleaning in spatial environments can be realized.

The outfan of temperature sensor and humidity sensor is connected with the common I/O port of central processing unit, and oxygen sensor and ammonia pass The outfan of sensor is connected with the analog port of central processing unit, the outfan of volatile organic matter sensor and central processing unit IIC peripheral hardware connects, and the outfan of dust sensor inputs IO with the seizure of central processing unit and is connected, and such rational deployment can To avoid the interference between each sensor, improve the precision of monitoring, improve the monitoring effect of air quality.

It is pointed out that the setting of main frame, server and mobile phone A PP, primary concern is that, the gas number after data process Transmit to main frame according to by wireless transport module, just reported a secondary data to main frame, normal condition every 15 seconds in abnormal cases Under reported once every 1 hour, after data report main frame, main frame carries out whole bag, then uploads onto the server, when user need During current air mass to be known, it is only necessary to refreshing mobile phone A PP interface, mobile phone A PP just can get new data from server Sending a signal, even if family no one, user also is understood that the situation of air quality to home.

It addition, central processing unit is PIC18 series monolithic, such structure designs, and the processing speed of data is faster, anti-dry Disturb ability higher.It practice, other kinds of processor can also be selected according to practical situation.

Temperature sensor and humidity sensor are physical sensors, and in the case of temperature difference, the electromotive force that thermocouple produces is different, A kind of energy transducer of thermocouple, converts heat energy into electric energy, can measure temperature by produced thermoelectrical potential, In the case of humidity difference, the capacitance of capacitive original paper can change, and has degree of precision.

The aerial content of oxygen is typically no variation in, but the minor variations of oxygen content can cause the many reflections of human body.For Measurement oxygen content, use the sensor of galvanic element be most economical effectively.The reduction that oxygen occurs on the working electrode (s is anti- The corresponding reduction reaction that should occur with cathode material produces electric current, and the size of electric current and the concentration of oxygen are directly proportional, by test electricity The size of stream i.e. can determine that the size of oxygen concentration.

Measure ammonia and mainly use the sensor with stannic oxide electrode, tin ash and other metal-oxide semiconductor (MOS)s Being sensitive to light concentration gas, during work, the agglomerate of quasiconductor can be heated and be resistively heated to uniform temperature, and detects it Conductance.Reproducibility or oxidizing gas are in the notable change adding the device conducts caused that interacts on hot surface with absorption oxygen. When tin ash element contacts with tested gas, once react with absorption oxygen, n the electronics fettered by oxygen discharged, As reacted with ammonia, plane of crystal conductance increases, and makes device resistance reduce, then by ball bearing made, resistance is converted into voltage Signal just can be measured.

Volatile organic matter of a great variety, such as aldehydes, arene, esters, its representative is exactly formaldehyde.Due to theirs Common denominator, it is possible to use integrated integral sensor measures, integral sensor volume is little, and precision is high.

The dust that people are touched substantially can be divided into two classes: PM2.5 and PM10, these granules according to particulate matter diameter Thing is evenly distributed in air under the disturbance of air-flow in a jumble.When specific light source irradiates the air particles of air-supply assembly consentrated air supply Time, collect the light intensity of air particles scattering, light intensity is converted to granule pulse signal;Turned with light intensity by input again The signal amplification module that the outfan of die change block connects, is amplified granule pulse signal, generates and amplifies granule pulse signal, After pulse signal exceedes the threshold value of comparator, output pulse signal.For receiving the pulse signal of output, count pulse letter Number time, i.e. can get the content of dust in environment.

The principle of above-described embodiment merely exemplary explanation present invention and effect thereof, not for limiting the present invention.Any it is familiar with this skill Above-described embodiment all can be modified under the spirit and the scope of the present invention or change by the personage of art.Therefore, all institutes Belong to and technical field has all equivalences that usually intellectual is completed under without departing from disclosed spirit and technological thought Modify or change, must be contained by the claim of the present invention.
