Zusammenfassung:	The utility model discloses an automatic control system of a dissolved oxygen meter of a blower. The automatic control system comprises an online dissolved oxygen meter and a blower frequency converter, wherein the online dissolved oxygen meter is connected to a PLC control cabinet; the blower frequency converter is connected with a blower for aerating an aerobic tank; the online dissolved oxygen meter comprises an online dissolved oxygen meter electrode probe arranged at a water outlet of the aerobic tank, the online dissolved oxygen meter electrode probe is connected to an online dissolved oxygen meter display screen and the PLC control cabinet. The PLC control cabinet is connected with a PLC display screen. According to the automatic control system disclosed by the utility model, the dissolved oxygen value in the aerobic tank is subjected to online monitoring by virtue of the online dissolved oxygen meter electrode probe at any time and the data from the online dissolved oxygen meter electrode probe is acquired and processed by virtue of the PLC control cabinet, and then the rotation speed and air flow of the blower are further subjected to online automatic adjustment by virtue of the blower frequency converter. By virtue of the automatic control system, the frequency of the blower motor is effectively increased and decreased, the purposes of controlling air flow and saving conservation are achieved, and meanwhile the control of constant dissolved oxygen value of different water qualities states is achieved.
