Underground water monitoring device for preventing underground water cross contamination and monitoring method thereof

The invention relates to the technical field of hydrogeological survey, and is to provide an underground water monitoring device and method for preventing underground water cross contamination. The device comprises a monitoring pipe and a water seepage port. The monitoring pipe comprises a water taking part and a water stop part; cavities are formed in the water taking part at intervals along theheight direction of the monitoring pipe; the water stop part is annular and wraps and is fixed to the side face of the water taking part; horizontal screw rods are rotationally connected to the positions, corresponding to the upper ends of the cavities, of the two sides of the water taking part; each screw rod is in threaded connection with a stop block, and the screw rod and the stop block are located in the water stop part; outlets allowing the stop blocks to penetrate out are formed in the positions, right opposite to the stop blocks, of the side face of the water stop part; and before monitoring, the monitoring pipe is located in the drill hole, and when the stop block slides to the end, away from the water taking part, of the corresponding screw rod, the stop block is exposed out of the outlet and extrudes the drill hole. The method has the advantages that cross contamination of underground water is reduced, and meanwhile, stratified water pumping and sampling are conducted on theaquifers of different depth sections in the drilled holes with the same hole diameter.

Task migration method and system of underwater ad hoc network based on edge gateway

The invention discloses a task migration method and system of an underwater ad hoc network based on an edge gateway. The method comprises the steps of selecting the edge gateway used for task migration management; adding sensor node information to a resource manager of the edge gateway; arranging the sensor node information by the edge gateway to form priority ranking of the nodes in the resourcequeue; arranging the task information of the original sensor nodes in a descending order by the edge gateway according to task priorities and puts the task information into a task queue of a task manager, and selecting an optimal task cooperation node; and migrating the task to the task cooperation node through the edge gateway for task calculation, and sending a calculation result to the originalsensor node. According to the method, the underwater self-organizing network node sends the collected seabed heterogeneous data to the nearest edge gateway, and the edge gateway migrates the task ofthe resource-limited node to the node with rich resources for cooperative completion, thereby balancing the network load, reducing the node energy consumption, and improving the marine data observation efficiency.
