With the reduction of available water resources, the development of industrialized recirculating aquaculture becomes the trend of modern fishery. In order to improve the automation degree of industrial recirculating aquaculture and to better combine it with the Internet of Things, an industrial recirculating aquaculture system based on INSPEC has been designed and introduced in this paper. The system adopts closed recirculating aquaculture technology, uses microfiltration machine, fluidized bed, low pressure oxygen mixing device and other domestic advanced circulating water aquaculture equipment to build the hardware system, constructs the control system using SIEMENS S7-300 PLC and other intelligent instruments, and uses INSPEC as a human-computer interaction platform and to integrate all the elements together. The system realizes the intelligent control of aquaculture process, precise control of aquaculture water quality, and networked control of aquaculture in industrialized recirculating aquaculture system, with the advantages such as higher degree of automation, stable operation, and strong expansion. While being easy to popularize, the system also provides theoretical and data basis for future welfare breeding system.
