| During the process of Marine Magnetotelluric Signal acquiring, we needto design a kind of non-realtime intelligent monitor and control drivingprogramme. In order to visually set the acquiring mode, personnel computersare used to control acquiring parameters that have visual interface developedby Microsoft Visual C++ language. Designed software can factitiously readparameter files by serial port, then realize prospective acquiring mode.Parameter files record the settings of measure stations and dataacquiring parameters. The settings of measure stations contain names ofthe districts ,work area, frequency and files. The settings of data acquiringparameters include acquiring frequency numbers,the sampling interval,acquiring time,electromagnetismic plus,starttime and endtime of the acquirngetc.Before every time running the data acquirng software, the user need tocompile the parameter file according to self requirements. The parameter fileis made up of many records which are controlled by chain tables.The acquiring software can set the work mode of serial port andparameters using MSComm activeX control. At the moment, the software hascompleted data acquirement according to RS-232 protocols. |
