The aquaponics system is a compound agricultural production system combine with recirculating aquaculture and hydroponic cultivation. It can produce aquatic products such as aquatic products and fruits and vegetables at the same time. Although the architecture is simple, its management is a cross-domain management method, which is more complicated than the former two.Intelligent management is one of the effective ways to improve the output and quality of the aquaponics system.In the past, PLC was used as the host to develop automation in agriculture, which was costly and difficult to maintain.The development of micro-control boards has accelerated the development of agricultural automation management in recent years.By automatically monitoring and controlling temperature, pH, dissolved oxygen, EC, etc., it can not only effectively reduce the manpower of management, but also increase the productivity of the system.A smart surveillance system for aquaponics systems was built this year.The relevant environmental factor data (temperature and humidity, illumination, E.C., pH, water temperature and dissolved oxygen, etc.) can be compared.The corresponding device is automatically turned on or off when the set range is exceeded.The environmental factor data monitored during the test was compared with the general test results, and the difference was less than 5%. At the same time, the establishment of a micro-element supplement fertilizer for Aquaponics can be used in the general plant growth process to supplement the insufficient trace elements in the system.
