“…The probe used in the cableless CPT system proposed in this paper is a cylinder made of metal material with a cone-shaped tip. The bottom area of the probe is 15 cm 2 , the top angle of the cone is 60°, and the cone tip can withstand a maximum force of 6300 N [ 31 ]. In the cone penetration test, a lot of probe rods will be installed behind the probe, and the probe pushing-down device will press the probe rod down at a constant speed, thereby driving the probe to continuously push down into the ground.…”

The traditional cone penetration test system uses cable to transmit data; as the probe goes deeper into the ground, the length of the cable will become longer. This makes the installation of the test equipment more complicated, and excessively long cables cause signal distortion and seriously affect data accuracy. To simplify the experimental equipment and improve the accuracy of data acquisition, a cableless cone penetration test system is proposed. The improved system uses an SD card to store the experimental data, as opposed to using cables for communication which, often lead to the distortion of signals caused by long-distance communication and data loss caused by accidental cable breaks. Therefore, the accuracy of the collected data is higher, and the experimental device is simplified. To evaluate the applicability and efficiency of our design, we have carried out exploration experiments with the sensor system proposed in this paper. The test results show that the experimental data collected by the new system are basically consistent with the data collected by traditional cable CPT equipment, and the accuracy of the collected data is higher. It is more reliable and accurate to analyze the comprehensive mechanical properties of the soil layers with the data collected by the new system.
