With the continuous development of national geological exploration, infrastructure construction and information technology, the traditional method of rock and soil composition analysis characterized by manual sampling, off-line experiment and expert judgment needs to be improved. As a typical in-situ test method, static cone penetration test is more and more used in geotechnical engineering because of its high efficiency, accuracy, small soil disturbance and good data continuity. In addition, static penetration test is an important method to evaluate engineering geological conditions and geological hazards. Therefore, there are more and more studies on the complete set of static penetration system. Firstly, the design of baseband board is introduced, including data acquisition module design, data storage module design, probe tilt control module design, baseband board communication module design, time synchronization module design and digital temperature control sensor module design, to design and develop the lower computer. Secondly, through the design of RTC clock interface, parameter setting interface and data transmission interface, the design of the host computer is completed to facilitate interaction with the computer. Finally, through the experimental results, a functional analysis of the simple static penetration probe acquisition system was carried out. Through the combination of high-performance and low-cost STM32 and various peripheral chips, the hardware and software configuration strategy of the baseband board is designed. At the same time, the research and development of the host computer function was completed, the design of the simple static penetration surveying system based on STM32 was completed, and the cost-effective rock mass component analysis solution was realized. To provide important support for the preliminary analysis of the project.
