摘要： An electric field sensor for underwater, including a sensing unit that senses a change in an electric field and transfers a sensing signal of the electric field to a signal line, a waterproof sealing unit that keeps a signal transferring portion of the sensing unit in a waterproof state, and a water-passing protection unit that shields and protects an exposed portion of the sensing unit. The sensing unit includes a nonconductive hollow pipe connected to the signal line, a sheet of carbon fiber that is wound around the outer surface of the hollow pipe and that senses an electric field, and a terminal ring that is electrically conductively installed at an end portion of the sheet of carbon fiber to provide a connection portion of the signal line and that is watertightly sealed by the waterproof sealing unit.

摘要： Provided are an underwater detector and a method for an underwater detection, and more particularly, an underwater detector including two direct current electrodes and a plurality of measurement electrodes in order to sense a movement of an object having conductivity different from that of water underwater. Since the underwater detector according to the present invention includes two direct current electrodes, a plurality of measurement electrodes, and a control and measurement module for measuring voltages of the plurality of measurement electrodes, the plurality of measurement electrodes each include an electrode control module and the electrode control module includes a first switch, a second switch, a controlling unit, and the like, the number of voltage measurement lines may be small and a voltage between two selected electrodes may be easily calculated.
摘要翻译： 本发明提供一种用于水下检测的水下检测器和方法，更具体地，涉及一种水下检测器，其包括两个直流电极和多个测量电极，以便感测具有与水下方的导电性不同的导电体的运动。 由于根据本发明的水下检测器包括两个直流电极，多个测量电极和用于测量多个测量电极的电压的控制和测量模块，所述多个测量电极各自包括电极控制模块和 电极控制模块包括第一开关，第二开关，控制单元等，电压测量线的数量可以较小，并且可以容易地计算两个所选择的电极之间的电压。
