Abstract
The utility model discloses a device used for updating a downhole instrument circuit board onboard central processing unit (CPU) program. The device used for updating the downhole instrument circuit board onboard CPU program overcomes the defects that at present, when a downhole instrument circuit board onboard CPU program is updated, efficiency is low, cost is high and huge danger exists. The device comprises a program reader and a firmware loader. The program reader reads a hexadecimal (HEX) document compiled by an updating program, sends the packed HEX document to the firmware loader, and receives and analyzes a data package passed back from the firmware loader. The firmware loader unpacks the HEX document, repacks the document to form data frames, sends the data frames out from a bus, packages a data packet uploaded by the bus, and passes away the data packet to the program reader. According to the device used for updating the downhole instrument circuit board onboard CPU program, a downhole instrument is free of being transferred outside a well mouth to be disassembled and program updating operations of a functional circuit board which is embedded on the interior of the instrument can be directly conducted.
