It is connected according to capture card Data Input Interface with pressure transmitter data output interface and does waterproof sealing；
The pressure transmitter, be put into and test in wellhole by second step, and enters level of ground water depth identified below, the depth root
The setting of height scene is excited according to head；
3rd step, after setting sample frequency, pressure value to be shown to stablize by the portable computer software interface, open
The dynamic pressure transmitter starts the frequency collection data according to setting；
After 4th step, the portable computer obtain the data of the pressure transmitter collection, then to the ground in experiment wellhole
Lower water level is instantaneously excited, and makes well water level in borehole that instantaneous lifting fluctuation occur；
5th step, by the portable computer software interface observation water pressure change and recovery process situation, treat number pressure
When being close to or up to initial value according to display, the data of collection are stored in portable computer storage dish by off-test.
The invention has the advantages that major embodiment is in the following areas：
1st, operation is simplified：The present invention uses the window interface of portable computer, complete by the button at operation control software interface
Paired data collection, control, preserve, and simplifies manual operation process, is grasped easy to field technician, improves work on the spot effect
Rate.
2nd, data acquisition is simplified：Operated by software, signal transmission, pass the data in experiment back portable computing in real time
Machine, in that context it may be convenient to store data into the storage dish of computer, data preserve form and fix, in addition, data acquisition quantity
Unrestricted, memory space shared by data storage can reach the size of portable computer hard disc subregion in theory.
3rd, the time is saved：The method of the present invention simplifies test operation process, shortens the time of field test；Pass through
Storage and arrangement of the control software to data use set form, data-handling procedure are simplified, easy to later data analysis meter
Calculate, save the Data Management Analysis time.
4th, place is adaptable：Electric power is provided to whole system using portable computer, has broken away from field test to electricity
The dependence of power, improves the flexibility of experiment, relaxes the requirement condition to test site.

Fig. 2 is the system block diagram for implementing the method for the present invention.
Embodiment
Elaborate below in conjunction with the accompanying drawings to the embodiment of the present invention, the present embodiment using technical solution of the present invention before
Put and implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, 2, drilling slug test test method of the present invention, comprises the following steps：
The first step, pass through USB data line and 2 data output interface of data collecting card by the USB interface of portable computer 1 and connect
Connect, for the data transfer between portable computer 1 and data collecting card 2, and for the power supply to data collecting card 2；Number
It is connected according to 2 Data Input Interface of capture card with 3 data output interface of pressure transmitter by signal transmission cable and pressure is become
3 data output interface of device is sent to do waterproof sealing processing, for pressure transmitter 3 and the data signal transmission of data collecting card 2, and
For the power supply to pressure transmitter 3；The analog signal that pressure transmitter 3 exports is converted to portable meter by data collecting card 2
The digital signal that calculation machine 1 can identify, data processing is carried out by portable computer 1, is converted to hydraulic pressure force data and is shown
And it is stored in portable computer 1；The measurement range of pressure transmitter 3 is 0-50kPa（Corresponding water-column is 0-5m）, essence
2 ‰ are spent, input voltage 24v, output current 4-20mA, pressure transmitter 3 are used for the number that water level signal is converted to 4-20mA
Word signal；
Second step, by pressure transmitter 3 be put into experiment wellhole 4 in, and enter level of ground water depth identified below, the depth according to
Head excitation requirement for height scene setting；
3rd step, the pressure value shown according to 1 software interface of portable computer judge whether signal transmission is normal；If data
Display is abnormal, checks whether each several part connection is correct, firmly；If data show the essential information for normally, inputting test section, will
In the information such as the length of test section, depth location, lithology, 3 position of pressure transmitter input 1 software of portable computer, then
The pressure zero setting button in software interface is clicked on, using the pressure after the stabilization observed at this time as pressure zero, i.e. initial value；
Finally determine the frequency acquisition of experiment, the sample frequency of setting is selected in frequency regulation button, start pressure transmitter 3 and start
According to the frequency collection data of setting；
After 4th step, the data by the acquisition collection of pressure transmitter 3 of portable computer 1, then to the underground in experiment wellhole 4
Water level is instantaneously excited, and makes water level in experiment wellhole 4 that instantaneous lifting fluctuation occur；
5th step, the change by 1 software interface of portable computer observation pressure value real-time display, if not up to pressure zero
Point, illustrates that water level does not recover to initial value, need to continue gathered data；If reaching initial zero, illustrate that water level is recovered to first
Initial value, off-test, the data of collection are stored in 1 storage dish of portable computer, and test section is included in the file of preservation
Information and test data etc..
Abnormal appearance can be determined whether during experiment in the form of real time inspection pressure-time curve.
