The invention discloses a single-phase intelligent electric energy meter based on the Internet of Things, and belongs to the technical field of single-phase intelligent electric energy meters, the single-phase intelligent electric energy meter comprises an electric energy meter body, the left and right sides of the electric energy meter body are provided with support plates, and the back surfaces of the support plates are fixedly connected with the front surface of a mounting plate. According to the electric energy meter, the electric energy meter body, the access terminal, the conductive sleeve, the conductive plate, the first contact piece, the second contact piece, the hydraulic rod, the conduction piece, the insulating plate and the contact rods are arranged, and the insulating plate drives the multiple contact rods to move upwards and make contact with the second contact piece in the upward moving process; the two second contact pieces on the left side and the two second contact pieces on the right side are conducted, so that the two output phase lines on the left side and the two output zero lines on the right side are communicated, normal circulation of current is achieved while the electric energy meter body is taken out, power-off processing is not needed in the process of replacing the electric energy meter body, and normal power utilization of a user is not affected. The power supply reliability is improved.
