Description

technical field [0001] The invention relates to an in-situ pore water harvesting column intelligent operation control system, which belongs to the technical field of marine exploration equipment. Background technique [0002] At present, when conducting deep-sea exploration and geological research, it is often necessary to collect the in-situ pore water contained in the deep-sea seabed mud with the help of the in-situ pore water extraction column, and the depth of the seabed where the samples are collected is generally not lower than 4000 Therefore, it is difficult to control the operation of the in-situ pore water collection column during sample collection. The current in-situ pore water collection column mainly utilizes the electromagnetic valve inside the in-situ pore water collection column to control the in-situ pore water. Controlling the collection work of the water collection column has low control accuracy and high failure rate, and there is no effective information...

[0002] At present, when conducting deep-sea exploration and geological research, it is often necessary to collect the in-situ pore water contained in the deep-sea seabed mud with the help of the in-situ pore water extraction column, and the depth of the seabed where the samples are collected is generally not lower than 4000 Therefore, it is difficult to control the operation of the in-situ pore water collection column during sample collection. The current in-situ pore water collection column mainly utilizes the electromagnetic valve inside the in-situ pore water collection column to control the in-situ pore water. Controlling the collection work of the water collection column has low control accuracy and high failure rate, and there is no effective information feedback on the operation status of the in-situ pore water collection column and the surrounding seabed environment of the in-situ pore water collection column, resulting in the current in-situ pore water collection. The automation degree and control ability of water column operation are relatively low, which further leads to the disadvantages of low sample collection efficiency and cannot effectively meet the needs of deep sea sample collection. In view of this situation, it is urgent to develop a professional in-situ pore water A control system with a high degree of automation and strong information feedback capabilities is used for the water collection column to meet the needs of actual use
