The invention provides an electricity meter information reporting system based on plastic optical fibers. The electricity meter information reporting system comprises a collecting terminal and multiple electricity meters. The collecting terminal comprises a first master control unit and a POF link management unit connected with the first master control unit. Each electricity meter comprises a second master control unit and a POF collecting unit connected with the second master control unit. The POF link management unit comprises multiple first communication ports. Each POF collecting unit comprises a second communication port. The second communication ports are connected with the first communication ports through the plastic optical fibers, so that a star structure with the POF link management unit as a central node and the POF collecting units as sub nodes is formed. According to the star structure, multiple communication links are formed, the collecting terminal is connected with the port of each electricity meter in a point-to-point mode, parallel meter reading can be achieved, the meters do not influence one another, and the data throughout rate is increased; because the POF link management unit is connected with the POF collecting units through the plastic optical fibers, the reliability of meter reading is improved, and the cost of the meter reading system is reduced.
