Specific embodiment
It elaborates below in conjunction with the accompanying drawings to the embodiment of the utility model, the present embodiment is with the utility model technology
Implemented under premised on scheme, give detailed embodiment and specific operating process, but the protection of the utility model
Scope is not limited to following embodiments.
Fig. 1, shown in 2, drilling slug test test system described in the utility model, including portable computer 1, data
Capture card 2 is arranged on the pressure transmitter 4 of level of ground water depth identified below and head excitation apparatus in experiment wellhole 3；Head
Excitation apparatus is made of more piece hand rod 5 with the cylindrical excitation block 6 for being screwed onto its lower end, for ground in provocative test wellhole 3
Lower water-level fluctuation；The USB interface of portable computer 1 is connected by USB data line with 2 data output interface of data collecting card,
For the data transmission between portable computer 1 and data collecting card 2, and for powering to data collecting card 2；Data acquisition
Block 2 Data Input Interfaces to be connected by signal transmission cable with 4 data output interface of pressure transmitter, and to pressure transmitter 4
Data output interface does waterproof sealing processing, for pressure transmitter 4 and the data signal transmission of data collecting card 2, and is used for
It powers to pressure transmitter 4.
As shown in figure 3, the utility model experimental test step is as follows：
The USB interface of portable computer 1 is passed through 2 data output interface of USB data line and data collecting card by the first step
Connection, for the data transmission between portable computer 1 and data collecting card 2, and for the power supply to data collecting card 2；
2 Data Input Interface of data collecting card is connected by signal transmission cable with 4 data output interface of pressure transmitter and does waterproof
Encapsulation process, for pressure transmitter 4 and the data signal transmission of data collecting card 2, and for the confession to pressure transmitter 4
Electricity；The number that the analog signal that pressure transmitter 4 exports is converted to portable computer 1 and can identified by data collecting card 2 is believed
Number, data processing is carried out by portable computer 1, hydraulic pressure force data is converted to and is shown and be stored in portable computer 1
It is interior；The measurement range of pressure transmitter 4 is 0-50kPa（Corresponding water-column is 0-5m）, precision 2 ‰, input voltage 24v,
