Embodiment
[0030] figure 1 It is a functional block diagram of the downhole program remote updating device based on the 485 bus of the present invention.
[0031] Such as figure 1 As shown, in this embodiment, the surface logging system includes a program processing module and a data sending module, and the program processing module further includes a program format analysis module and a data format encapsulation module. The software development platform for remote updating of downhole programs includes CCS development environment and QUARTUS development environment.
[0032] The program format analysis module converts the DSP update program compiled and generated by the CCS development environment, that is, the COFF file with the .OUT suffix, into a .BIN file that only contains download information, and then encapsulates the module number in the data format with the CPLD configuration file generated by the QUARTUS development environment , that is, the .JBC file is combined and packag...
