Any failure warning is as appearing significantly from the part of device data downloaded.
Open first valve 38 and second valve 60 (step 104) and activate pump 48 (step 106), have the self-drilling up-to-date gaseous sample of coming to guarantee sensor so that gas is passed above-mentioned gas flow paths from the boring pumping.VOC detecting device 40 and VOC gatherer 42 are positioned at the front of filtrator 44, otherwise filtrator 44 will be removed VOC from gas flow.Can be through the collected VOC of VOC gatherer through removing the VOC gatherer and making VOC be eluted to instrument such as in the gas chromatograph and by quantitatively.The measurement (step 108) of VOC concentration is carried out through VOC detecting device 40.Remove moisture and particulate through filtrator 44.
Then, borehole gases is passed detecting device 50, analyzes (step 110) in detecting device 50 place's borehole gases through gas tester 57,54,56 and 58.
Simultaneous gas pressure measurement (step 112) carries out through first pressure transducer 38, and the atmospheric pressure force measurement of reference carries out through second pressure transducer 66.Record sensing time and pump operated time span (step 114).Rule of thumb measure or through calculating, can confirm that when pump 48 operations time per unit passes the gas volume of device 8.Therefore, can confirm how many gas volumes that in given arbitrarily test period, passes device is.This data storing is in controller/storer 70.Then, can obtain the measured value of VOC concentration divided by the gas volume that passes gatherer through the amount of the collected VOC of VOC gatherer.
Then, close first valve 38 and second valve 60 (step 116).Come self-drilling gas to circulate and turn back to boring through the boring end of device.
Through gas tester 52,54,56 and 58, carry out the measurement of gas variable.Can monitor any suitable variable, comprise in existence or shortage, gas concentration level, the gaseous tension of specific gas, the moisture content in the gas etc. one or more.Be stored in controller/storer 70 from the gas variable data measured.
Reset the timer in the controller 70, make and to carry out periodic measurement subsequently.
The data that are stored in controller/storer 70 can be downloaded from hardwired connects via connector 82 or through wireless transmission.This connection also can be used for programmable controller 70, to come operating means 8 according to required.For example, the frequency of variable such as sampling can be set also, no matter sample regular or irregular, whether should regularly be disposed to atmosphere or the like.
Is the basis with above-mentioned, if water content detection device 80 detects the existence of moisture in device, then the detection of moisture signal is sent to and can takes appropriate steps in the controller 70 of (such as stopping device 8, transmit caution signal, light emergency warning lamp or the like).But this protective device 8 is without prejudice and avoids reading the reading of pollution.
Because gas is assembled a period of time in boring, therefore making boring and atmosphere is favourable with the pressure that reduces the there, but also through allowing boring and atmospheric equilibrium to offer an opportunity for restarting sampling operation effectively.Therefore, the reconfigurable mutation analysis that is used for the baseline of monitoring arbitrarily and can carries out the gas variable of a period of time.Installing 8 configurable one-tenth periodically or according to instruction ventilates to atmosphere boring.
Therefore, portable self contained IGM device is provided, it can be deployed in the boring to read the periodic data reading of the gas variable in the boring expediently.
Particularly, of the present inventionly preferred embodiment make it possible to monitor VOC.VOC detecting device and VOC controller make that with the combination of confirming of the gas volume that passes device calculating can be realizing of how changing through absolute concentration and the absolute concentration of the specific VOC in the boring together in a period of time.Through the result of time mark, the variation of VOC in a period of time can be monitored, for example make can with other time-the variable phenomenon compares such as atmospheric pressure or weather conditions.
