Large batches are automatically sorted and stored, which greatly facilitates environmental monitoring and sampling.

The invention discloses a phase shift compensation method for single resistance current sampling. The method comprises the steps of (S20) judging whether T1+T2 is larger than 2*Tmin or not, executing a step S(31) if so, and executing a step (S32) if not; (S31) judging whether T1 is larger than or equal to Tmin, executing a step (S41) if so, and carrying out phase shift compensation on a middle phase and then executing a step (S41) if not, (S32) judging whether T1 is larger than or equal to Tmin, and executing a step (S42) if so, and carrying out phase shift compensation on a maximum phase and then executing a step (S42) if not; (S41) judging whether T2 is larger than or equal to Tmin, executing a step (S51) if so, and carrying out phase shift compensation on a middle phase and then executing a step (S51) if not; (S42) judging whether T2 is larger than or equal to Tmin, executing a step (S52) if so, and carrying out phase shift compensation on a minimum phase and then executing a step (S52) if not, (S51) sampling at two sides of the maximum phase and the minimum phase, and (S52) sampling at the same sides of the maximum phase and the middle phase. According to the phase shift compensation method, T1 or T2 is always larger than the minimum current sampling time Tmin, and thus a sampling blind area is completely eliminated.

The invention discloses a soft robot for sampling water in deep waters, comprising: at least one base part, the base part is a flexible part, the base part can be filled with gas, and when the base part is filled with gas, the The base part can wriggle forward; several probes are arranged on the outside of the base part at intervals, and the probes can monitor the outside state of the base part; air is pumped into the base part through an air pump, and the inside of the base part is provided with Several channels, the change of gas pressure in several channels can make the base part squirm, turn or turn around, so that the soft robot has a variety of operating states, and can be threaded according to different designs of the building to prevent the wire from being stuck in the reserved hole of the building , Improve the flexibility and safety of threading.
