The utility model is that a kind of high-performance low-power-consumption one-chip computer and high-capacity FLASH memory of adopting is the volume detection tape deck in down-hole little, low in energy consumption of core development.Pocket computer is to have USB interface, the universal notebook computer that probe is carried out parameter setting, data readback and analyzing and processing special-purpose software is housed, after probe is taken out by the down-hole, utilize USB interface cable one end to be connected with the USB interface of record probe circuit plate, other end plug can be connected with the USB interface of portable computer.
Compared with prior art, the utility model has following advantage:
1) under the situation that does not need real-time Transmission,, need not the ground logging cable, saving equipment and construction cost because probe carries battery operatedly.
2) gather and the volume of memory circuit plate reduces greatly, can accomplish that the well casing annular space surveys, further enlarge range of application.
3) data of playback can be handled on PC very easily flexibly after acquisition and recording finished.
