基于水产物联服务平台的智能增氧控制系统的开发
Development of intelligent aeration control system based on internet of things services platform
摘要
Abstract
Traditional methods of aeration cannot meet the needs of modern and intelligent aquaculture with the advance of technology. Control strategies in existing automatic aeration systems are not smart enough to react to the changes in dissolved oxygen. The development of this intelligent aeration control system was to solve above problems. Programmable logic controller (PLC) was used as the central progressing unit (CPU) in intelligent aeration control system which was based on the Internet of Things services platform. PLC was connected to the Internet by GPRS modem to communicate with the server and exchange data with the database. Optical dissolved oxygen sensors were adjusted to the system to monitor water quality and collect data. The wireless sensor network, which was based on ZigBee technology, was to transmit data in the intelligent system. Coordinator was installed beside the PLC to coordinate other devices in the pond. The wireless sensor network was powered by solar cells which were mounted on the lfoat bowls. Being dependent on the control parameters, the controller used dissolved oxygen status determination mechanism to divide dissolved oxygen into ifve states, and outputting a corresponding control strategy. The results show that the intelligent control system can run stably under a long term operation test. Communication and data transmission between controller and server or devices were unobstructed, timely and reliable. The control system can determine the status of the pond dissolved oxygen based on the settings of the control parameter, and trigger the system mechanisms for water diversion or aeration intelligently. Design of intelligent aeration control system achieves the requirements for ponds aquaculture because of stable and efifcient control effect. Risks of the ifsh-farming under the management of intelligent aeration control system can be reduced and production efficiency was improved. The system can be unattended and would be more efifcient and popular when it is utilized widely in aquaculture.关键词
