Ropeless static penetrometer and method for acquiring and processing data

Abstract

The invention discloses a ropeless static penetrometer and a method for acquiring and processing data. The ropeless static penetrometer comprises an underground static probing DAC (data acquisition card), a management system of a static probing data upper computer and an underground static probing data acquisition instrument, wherein the management system of the static probing data upper computer is used for processing and displaying data which is acquired by and stored in the underground static probing DAC, and the underground static probing data acquisition instrument is used for uploading the data. The method comprises the following steps: 1, acquiring and processing a signal of an initial detection value of a static prober in real time; 2, acquiring, processing and displaying depth signals of a probe rod and signals output by the underground static probing DAC in real time; 3, uploading the data; and 4, processing and displaying static probing data. The structure is simple, the design is reasonable, the operation is convenient and quick, the data memory space is large, the storage time is long, the continuous working time is long, the reliability is high, the working efficiency is high, the data processing capacity is strong, the use efficiency is good, and the promotion and application are convenient.

Description

technical field [0001] The invention belongs to the technical field of engineering geological survey, and in particular relates to a cableless static penetration sounder and a data acquisition and processing method. Background technique [0002] Static sounding is an in-situ test method in engineering geological survey, which is suitable for soft soil, general cohesive soil, silt and sandy soil. In areas with many soft soils, static sounding can improve The reliability of survey results. [0003] At present, the static penetrometers used in China mainly use cables to transmit pressure signals and depth signals. Due to the widespread use of computers, the static penetration test can input standard programs into the static penetration data acquisition system through the computer to control the static penetration test process, thereby obtaining rapid and accurate results. However, during the static penetration test, there is a lot of inconvenience in connecting the probe to t...

Problems solved by technology

Although these two transmission methods solve the inconvenience of the cable method very well, their disadvantages are also obvious, which are mainly reflected in the following two points: First, due to the unpredictability of the underground environment, radio and light transmission will change in different environments , so that the signals transmitted to the ground through these two methods are seriously interfered, and the measurement results have large deviations; secondly, the convenience of these two methods also greatly increases the cost of the system

Due to these unfavorable factors, although it solves the inconvenience of traditional data collection, its promotion and application are still difficult, and there are very few in China.

[0005] From the above content, it can be seen that the current domestic and foreign research on static penetration can not meet the actual needs well.
