The utility model discloses a remote handheld terminal. The terminal comprises a signal capturing interface, a signal processing module and a digital processing module; the signal capturing interface is electrically connected with electric wires and acquires electric wire carrier signals; an input end circuit of the signal processing module is connected with an output end of the signal capturing interface, receives the electric wire carrier signals output by the signal capturing interface, performs signal demodulation and decoding and then outputs phase line identification code information; and an input end circuit signal of the digital processing module is connected with an output end of the signal processing module, receives the phase line identification code information, records the strength of the signal, performs comparison on strengths of the signals obtained through detecting the different electric wires, and outputs electric wire identification results. The electric wire carrier signals are introduced to the electric wires, acquisition and identification are performed by the remote handheld terminal, the electric wires are identified through differences of the electric wire carrier signals, operation efficiency is high, and identification accuracy is improved at the same time.
