The distributed and centralized data collecting system of microsounding

The paper describes the principal and the studying level of micro sounding in the world, introduces the characteristics of the distributed centralized survey system and analyses the communication between the host computer and client server, the elimination of the influence of the high grounding resistance, the bases of work frequency selection and the soft hardware structure of the whole machine. The system applies the principal and subordinate distributed multi machine communication to the geophysics instrument for the first time, and the technology of the principal and subordinate distributed multi machine communication can also be fit for other electric instruments such as dual frequency, multi frequency IP machine. It has some practical value. In the end, the paper presents the results of the model experiments by this system.
