The traditional aquaculture industry is characterized by extensive feeding methods such as sacrificing natural environmental resources and a large amount of material consumption. It has low economic benefits and pollutes the water environment. More and more modern aquaculture methods, such as cage culture and flow aquaculture, etc., use the ecological fisheries produced by the three-dimensional use of water areas and land and water to produce sustainable use of fishery resources.
The development of Internet of Things technology has created conditions for the production of smart aquaculture. The intelligent aquaculture system based on the Internet of Things technology such as intelligent sensing technology, intelligent processing technology and intelligent control integrates functions of data, real-time image collection, wireless transmission, intelligent processing and issuance of prediction and early warning information, and auxiliary decision-making. The accurate detection of parameters, the reliable transmission of data, the intelligent processing of information and the intelligent automatic control of the control mechanism realize the management of aquaculture.
The aquaculture environment intelligent monitoring system is developed for the aquaculture intensive, high-yield, efficient, ecological and safe development needs, based on intelligent sensing, wireless sensor network, communication, intelligent processing and intelligent control and other Internet of things technology, water quality environment The aquaculture IoT system with the functions of online parameter collection, intelligent networking, wireless transmission, intelligent processing, early warning information release, decision support, remote and automatic control.
Farmers can use mobile phones, PDAs, computers and other information terminals to grasp real-time aquaculture environment information, obtain abnormal alarm information and water quality warning information in a timely manner, and can automatically adjust control equipment in real time according to water quality monitoring results to achieve scientific aquaculture cultivation. And management, and ultimately achieve the goals of energy saving and consumption reduction, green environmental protection, and increase production and income.
Generally speaking, the Internet of Things system is composed of subsystems such as water quality monitoring station, aeration control station, on-site and remote monitoring center.
The water quality monitoring station can be optionally equipped with dissolved oxygen sensor, pH sensor, water level sensor, salinity sensor, turbidity sensor, etc. In conjunction with the intelligent data collector, it mainly realizes online collection, processing and transmission of water quality environmental parameters of the farm.
The aeration control station includes a wireless control terminal, a distribution box, an air compressor and an aeration and aeration pipeline (or aeration machine). The wireless control terminal gathers the information collected by the water quality monitoring station. According to the needs of different breeding species for dissolved oxygen, Control the action of aeration equipment through the algorithm model.
The on-site monitoring center includes a WSN wireless access point and an on-site monitoring computer. The data collected by the wireless control terminal is aggregated to the on-site monitoring computer through the wireless access point. Users can query the water quality parameter data locally, and the monitoring computer analyzes and processes the data. Control decisions, send control instructions to the distribution box through the wireless access point.
The remote monitoring center receives the data information gathered by the wireless control terminal through the GPRS remote access point. Users can query the water quality information remotely through mobile phones, PDAs, computers and other information terminals. At the same time, they can also make control decisions by analyzing and processing the data. Control aeration equipment.
After more than three years of research and development and practical use, we have developed a completely independent intellectual property rights aquaculture Internet of Things solution: aquaculture water quality online monitoring system. The system includes high-precision sensor probes, data collection and analysis terminals, wireless communication terminals, intelligent oxygen transmission control cabinets, intelligent mobile display terminals, Internet cloud servers, online mobile terminal display control software and other complete software and hardware facilities, providing information for aquaculture. The realization of intelligentization and intelligence provides a powerful scientific and technological backing.
The system allows managers in related fields to view the sampling data of probes at various monitoring sites online. At the same time, it provides a text message reminder function, which is convenient for managers to timely understand the value of each parameter of water quality, so that managers can get the news of water quality problem warning in the first time. In order to take timely measures to avoid losses.
When the system is running, the data of dissolved oxygen and temperature collected by RIU is transmitted to the WEB server in real time through DTU. The WEB server stores these data in real time and provides users with the function of inquiring at any time in the form of a web page. At the same time, according to the alarm or prompt conditions set by the user, the system will send the dissolved oxygen and temperature information to the mobile phone designated by the user in real time via SMS, so that the user can understand the water quality status anytime, anywhere.
The following figure shows the display pages of the WEB and mobile terminals respectively.
