The invention discloses an aerator control system and method based on a mobile internet and a cloud computing technology. The aerator control system comprises user clients, a cloud server, a wireless communication module, a microcontroller, a relay, a dissolved oxygen probe, a temperature sensor, and a current transformer; all the relay, the dissolved oxygen probe, the temperature sensor and the current transformer are connected with the microcontroller, the microcontroller is connected with the cloud server through the wireless communication module, and the user client is connected with the cloud server; the user clients include a PC (personal computer) client and an intelligent mobile device client. The aerator control system also includes a GPS (global positioning system) positioning module, a display module, an LED light and a buzzer. The aerator control system provides system user management, aerator equipment and data management and other functions, can push information to specified user cellphones according to system-set dissolved oxygen overrun, aerating pump abnormality, power supply outage, communication link interrupt and other warning conditions, and users may also access and manage the aerator control system through a cellphone APP or browser.
