The invention discloses an electric automobile charging pile electric energy quality monitoring processing method based on the Internet of things. According to the method, a work state and the electric energy quality information of a charging pile are acquired by a monitoring module through an electric energy measurement sensor, the electric energy quality data is transmitted to a main data analysis processing station, the data is determined and analyzed, if electric energy quality is lower than a lowest threshold, an early warning signal is sent by the main data analysis processing station to an online monitoring terminal, an instruction is further sent to a regional electric energy processing device, regional unified electric energy quality processing can be realized, and the main data analysis processing station keeps interaction contact with the online monitoring system terminal through a communication module; the electric energy processing device comprises a voltage compensator and an electric power stabilizer. The method is advantaged in that manual operation is reduced, untimeliness of manual operation can be avoided, electric energy quality processing efficiency and a power distribution network automation degree are improved, electric automobile storage batteries and other loads can be effectively protected, and service life of the batteries and the loads is prolonged.
