Abstract：Aerator is the guarantee of high density and production of shrimp culture. To reduce the loss caused by aerator fault for shrimp farmers, and ensure continuous and reliable operation of the aerator, this paper proposed an aerator-monitoring system based on GSM communication network. This system consists of a mobile terminal and monitoring execution terminal, and the the main control chip of latter is the STC12C5A32S2. AC current detection circuit and SIM900 module are chosen for remote communication and aerator working condition monitoring. Through the mobile terminal, shrimp farmers can achieve the real-time monitoring and control of the aerator. When the aerator is abnormal, the system will immediately inform the farmers by calling and enable local audible alarm; if spare aerator is equipped by the shrimp farmers, the system will automatically open the spare aerator. The application showed that the system could satisfy the users' requirement for real-time monitoring for the aerator , which was characterized by stable running, simple installation, convenient operation, and effective reduction of the strength of inspections and maintenance work for shrimp farmers.
