Integration and Research of the Multifunctional Geological Survey Information Acquisition System

In traditional geological surveys, the compass, GPS and record forms are usually used as tools. However, these tools are time-consuming and less efficient, and bring certain inconvenience to the field survey work. In addition, misoperations may occur during data acquisition and processing as well, seriously affecting the quality of survey data. With the development of mobile communication technologies, the computing and processing performance of intelligent mobile terminals is getting more and more powerful, and they are basically integrated with hardware devices such as the GPS, gyroscope and high-definition camera. The integration of GPS, gyroscope and close-range photogrammetry contributes to the establishment of the field geological survey data acquisition system that can quickly acquire distance and spatial position information and fill in the information. By making full use of intelligent mobile terminals to solve the problem of data acquisition and recording during the traditional field geological survey, an App, i.e.the mobile terminal-based field geological survey data acquisition system was developed, which can improve the field survey and indoor data collation efficiency. In this study, The field geological survey acquisition system(APP) based on the Android operating platform was developed, using dart2.9.0 as the client development language, python3. 7.7 as the server-side development language and MySQL6.0 as the database. With the system, the coordinate measurement (single-point positioning and remote telemetry), the attitude measurement, length measurement, photography and information reporting and other functions can be realized, which improves the accuracy of field geological surveys, increases the work efficiency and control quality, and realizes the whole-process supervision and log recording.
