The invention discloses an ordered charging control system and method based on master-slave RS485 communication, and belongs to the technical field of ordered charging control. The system comprises a master device and a plurality of slave devices. The main device is connected with a gateway electricity meter in a station and collects an active power value in the station in real time. The master device is connected with the plurality of slave devices through an RS485 communication network; the master device is configured with a master device address, a slave device address range and a station output power threshold; and the slave equipment is configured with an equipment address. The method comprises the steps that a master device collects the total active power of a station and operation data of each slave device in real time; the master device determines the output power of each slave device based on a station output power threshold preset in advance in combination with the total active power and the operation data of each slave device; and the master device transmits the determined output power of each slave device to the corresponding slave device through an RS485 communication network. According to the invention, additional ordered charging equipment is prevented from being added to each charging station.
