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.

锥穿透试验临时数据存储方法的理论研究与实现

传统的锥入度测试系统使用电缆传输数据。随着探头深入地下，电缆的长度将变长。这使得测试设备的安装更加复杂，并且过长的电缆会导致信号失真并严重影响数据准确性。为了简化实验设备，提高数据采集的准确性，提出了一种无电缆锥入度测试系统。改进的系统使用SD卡存储实验数据，而不是使用电缆进行通信，这通常会导致由于长距离通信引起的信号失真以及由于电缆意外断开而导致的数据丢失。因此，所收集数据的准确性较高，并且简化了实验装置。为了评估我们设计的适用性和效率，我们对本文提出的传感器系统进行了探索实验。测试结果表明，新系统采集到的实验数据与传统电缆CPT设备采集到的数据基本吻合，采集数据的准确性更高。使用新系统收集的数据来分析土壤层的综合机械性能更加可靠和准确。
