Abstract

The invention discloses a pipeline type karst underground space detection device and method based on WIFI positioning. The device comprises a plurality of detection sensors, connecting wires, a controller and a data processing terminal, wherein the detection sensors are sequentially arranged side by side, the adjacent detection sensors are connected through the connecting wires, the detection sensor located at the tail end is connected with the controller through the connecting wires, and the detection sensors are in network connection with the data processing terminal. The detection method comprises the following steps of S1, searching an underground river skylight so as to place a detection sensor; S2, estimating a detection length, and connecting a plurality of detection sensors to theconnecting line according to the detection length; and S3, putting the detection sensor and the connecting line into the underground river, transmitting detected data to a data processing terminal bythe detection sensor through a WIFI module, and analyzing the data by the data processing terminal to form a three-dimensional underground river distribution map, thereby completing the detection operation of the underground river pipeline.

Description

technical field [0001] The invention relates to the field of karst underground space detection, in particular to a pipe-type karst underground space detection device and detection method based on WIFI positioning. Background technique [0002] The distribution and scale of karst geological bodies, such as karst underground rivers, large karst pipelines, and caves, need to be identified for land space planning, underground engineering construction, and water resource development and utilization in karst areas. [0003] At present, the detection of karst underground space at home and abroad mainly uses geophysical exploration methods, such as seismic, electrical, magnetic, etc., but due to the influence of geological conditions, site environment and the multiple solutions of geophysical exploration itself, the detection effect is not ideal, especially For the detection of deep and long-distance karst pipelines or underground rivers, there are not many effective means, and accu...

Problems solved by technology

[0003] At present, the detection of karst underground space at home and abroad mainly uses geophysical exploration methods, such as seismic, electrical, magnetic, etc., but due to the influence of geological conditions, site environment and the multiple solutions of geophysical exploration itself, the detection effect is not ideal, especially For the detection of deep and long-distance karst pipelines or underground rivers, there are not many effective means, and accurate positioning cannot be achieved

For the detection of the connectivity of karst underground rivers, tracer tests can better solve this problem, but generally it can only confirm that the tracer input point and the receiving point are connected, and it is impossible to finely describe the subsurface between the input point and the receiving point. The movement path and morphological scale of the river, and limited by conditions such as rainfall and the accuracy of detection instruments, are prone to missed judgments, which are passive detection methods

At the same time, because karst underground rivers generally develop deep underground and have a long distance, the use of input detection equipment with GPS positioning function cannot be used for positioning and detection because there is no way to receive satellite signals; therefore, it is necessary to study a A kind of underground space detection device to solve the above problems
