An equipment for aquaculture was developed which consisted of unmanned automatic cruise boat, environmental and ecological monitoring devices and remote service platform. It achieved a real- time online monitoring and precise control of field devices with high efficiency and low cost. By using the technology of automatic heading speed control, navigation and anti-collision, the unmanned boat realized the function of automatic cruise. Then, the boat carried a self-made multi-functional device （one controller with different probes） to obtain ecological characteristics and various environmental parameters at each specified location, including water temperature, pH value, dissolved oxygen （DO）, and oxidation-reduction potential （ORP）. Detection parameters could be expanded according to the actual needs. The boat could obviously reduce the number of monitoring device and effectively improve its detection accuracy. Furthermore, information fusion, statistical analysis and configuration control were used to analyze the obtained data and precisely manage field aquaculture equipment. The result showed that the integrated monitoring equipment could meet the needs of large-scale and factory-style aquaculture, and promoted the wider application of precision agriculture equipment in ordinary farmers.
