Be engaged in device on, transmission while, by GNSS units obtain positional information, according to positional information calculation out position twice whether
Offset, when judging that offset distance exceedes alarm distance, that is, produce stolen alarm signal.
2nd, sensor embodiment
The electrochemical sensor signal of gridding miniature air monitoring sub-station collection is faint nA level current signals, therefore
Need using low input offset current, low input offset voltage, the low high precision operating amplifier 5 for exporting temperature drift.Such ability
The small-signal for ensureing to gather is unaffected and disturbs.In order that stable output signal, eliminates various High-frequency Interferences, in high accuracy
The output end of operational amplifier 5 is needed by one-stage low-pass twt amplifier.Although faint electrochemical sensor signal by
Amplification, but still it is very faint, it is therefore desirable to high-precision analog/digital converter is used, so as to realize the resolution of the signal of collection
Rate precision is sufficiently high.Due to sharing No. 4 electrochemical sensors, therefore the analog/digital converter selected should be that belt switch is cut
The multi-channel analog/digital converter changed.
Specifically, it is defeated as shown in Fig. 2 the nA levels electric current of electrochemical sensor is after the amplification of high precision operating amplifier 5
Go out for mv magnitude voltage signals；The voltage signal of output passes through low pass filter 6, filters out High-frequency Interference；Stable signal input
To 16 high-precision analog/digital quantizers (resolution ratio 1/65536), the signal of measurement is set to be accurate to 0.01mv, completely
It disclosure satisfy that the requirement of measurement.16 high-precision analog/digital quantizers are led to by digital interface and central processing unit 8
Letter, complete the switching of unlike signal passage and the collection of signal.
There are air inlet and air outlet in particulate matter sensors 10, carry mini-fan 11, fan inhales air from air inlet
Enter in particulate matter sensors 10, exclude air from air outlet, light scattering principle is utilized in whole gas circuit, measure in air
The particulate matter number of grain thing concentration and various different-grain diameters.Measurement result sends central processing unit 8 to by digital interface.
In the present embodiment, the measurement of the electrochemical sensor of gridding miniature air quality-monitoring substation belongs to passive survey
When amount, only outside air are diffused into inside electrochemical sensor, effective measurement result can be just obtained, this causes the reality of measurement
When property is poor.In order to obtain measurement result in real time, it is necessary to increase gas circuit, outside air is set to enter electrochemical sensing in real time
Inside device.Consider power consumption and the limiting factor of flow, low-voltage Ultra-Low Speed DC micro fan need to be used.Differentiated to improve
Rate, the special electrochemical sensor of air quality monitoring of lower range need to be used.
, will be extraneous fresh with 400mL/min ultralow speed therefore the present embodiment preferably selects 3.3V miniature low speed fan
Air sucks sensor, meets the real-time measurement request of sensor, while increase between mini-fan and sensor and dehumidified
Device is filtered, the humidity of air is met the requirement of measurement, fresh air is after electrochemical sensor, from electrochemical sensor
Both sides are returned in air.
The SO at gridding miniature air station2Electrochemical sensor is adopted using 0-1000ppb range, CO electrochemical sensors
With 0-20ppm range, NO2Electrochemical sensor uses 0-250ppb range, O3Electrochemical sensor is using 0-250ppb's
Range.Such measurement range, the resolution ratio of measurement will be greatly improved.

It can be adjusted correspondingly completely according to the use demand of reality, i.e., can also be further in order to realize more accurate measurement
Improve the range of various electrochemical sensors.Therefore any obvious change and adjustment the present embodiment protection domain it
It is interior.
3rd, anti-theft feature embodiment
Because gridding miniature air monitoring sub-station realizes miniaturization, in order to prevent being removed, it is desirable to provide antitheft work(
Energy.When antitheft, if GSM antenna or GNSS antenna are removed, alarm can not be realized, this is also to need what is solved to ask
Topic.GNSS function collection GPS and the Big Dipper are positioned at one, and constant speed is fast, and precision is higher, are good solutions.
The micro energy lose mobile network transport module 9 that GSM units and GNSS Elementary Functions are integrated in one in the present embodiment,
The connection with central processing unit 8 can be realized by a digital interface.Central processing unit 8 realizes control by digital interface
The timing start-up function of GSM units and GNSS units, after start, this positional information is obtained by GNSS units, then
Compared with the positional information obtained with last time, by the geometrical relationship of longitude and latitude and earth radius, position twice is calculated
Deviation, if position deviation twice exceedes normal value, triggering alarm, after alarm, GSM units and GNSS units will be every 1
Second to server send a positional information, while to related director send alarming short message breath.
4th, Low-power Technology solution
Gridding miniature air monitoring sub-station should realize miniaturization, measure many sensor parameters again；Need simultaneously
Consider the battery powered situation of continuous rainy days.Therefore, requirement of the gridding miniature air monitoring sub-station to power consumption is very high.
In whole circuit, GSM units, GNSS units, particulate matter measurement are power consumption the best parts, therefore, it is necessary to examine during circuit design
Consider to their power supply.
In the present embodiment, because GSM units and GNSS units employ all in one intergration models, it enormously simplify and set
Meter, while farthest reduce power consumption；In addition, as shown in Fig. 2 either the power supply of GSM units or GNSS units is all
Working time in intermittent operation mode, can largely be reduced, so as to reduce power consumption with independent control.Other particulate matter
At work, fan is maximum power consuming units to sensor 10, in intermittent operation mode, when not working, and central processing
Device 8 can control particulate matter sensors 10 to enter park mode by digital interface, fan is stopped, so also can be maximum
Reduce to degree the power consumption of particulate matter sensors 10.
In addition, whole system designs, it is preferred to use low-voltage lithium battery power supply, hardware low-dropout regulator LDO voltage stabilizings,
Also the energy loss during level conversion can farthest be reduced.
The present invention is under conditions of measurement accuracy is ensured, on the one hand, air quality monitoring is miniaturized, before being greatly lowered
Phase builds input and later stage operation maintenance cost；On the other hand, realize that air quality gridding monitors, be some areas air capacity
The dynamic analysis of change provide data, so as to be country and ring in terms of Causes for Pollution, pollution sources explanation, in terms of heavily contaminated reply
Border protection authorities provide Feasibility Solution.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The most wide scope caused.
