Summary:An intelligent polar identifying device includes an electromagnetic module (1) and a control circuit (2). The electromagnetic module (1) includes a magnetic inductor (101), an active contact strip (102) coaxial with the magnetic inductor (101) and a fixed contact strip (103). The control circuit (2) comprises a reverse connection alarm protection module and a straight connection conducting module. The reverse connection alarm protection module includes an alarm module and a protection module in parallel. The protection module includes a second diode (D2) and a photoelectric coupler (U1) in series. The straight connection conduction module includes a conducting part and an indicating module that are electrically connected with the photoelectric coupler (U1). The device utilizes magnetic force for controlling and insures automatically identify the connecting state of the electric apparatus weather clamps is rightly connected to a positive pole and a cathode of the exterior power source and guarantees normal charging, thus protecting the power source and the electric apparatus.
