The invention relates to an intelligent charging pile device for a new energy automobile. The intelligent charging pile device comprises a remote signaling isolation input circuit, a control guide circuit and a temperature monitoring and fingerprint processing circuit. The remote signaling isolation input circuit processes an input signal through voltage stabilization, filtering and an optoelectronic isolator, interacts with a control signal through the isolator, can identify the input signal to control detected equipment to be in a working/stopping state, and effectively avoids interference caused by electrical characteristics and severe working environments. The control guide circuit can judge the connection condition of the alternating current charging pile and the electric vehicle and judge the charging power of the charging pile. The temperature monitoring and fingerprint processing circuit judges the working state of the charging pile by measuring the temperature of the circuit and analyzing an incoming signal, and screens out a real-time monitoring effective signal; and the fingerprint processing circuit finds out basically same matching points through the reference point, performs feature matching on user data and a fingerprint database through signal processing, and permits to execute charging operation if matching succeeds, thereby realizing intelligent man-machine interaction.
