【Abstract】 In order to acquire ultra long period magnetotelluric signal intelligently, this paper designs data acquisition broad hardware, replants Windows CE 5.0 kernel, develops the monolithic stream drivers for data acquisition broad under Windows CE kernel, and designs the acquisition application based on the driver. The experiment on field shows that this instrument has high credibility, high precision, low power consumption, and is easy to be operated.更多还原
