Intelligent Monitoring system of Water quality Environment in Modern Aquaculture

The continuous deepening of scientific research and technology of agricultural and aquatic products in China and the continuous improvement of awareness of environmental protection have put forward higher requirements for continuous real-time monitoring of water quality parameters. however, at present, most of China's agricultural production still stays at the traditional level of relying on manual experience, and few automatic control is realized. Aquaculture environment intelligent system is a new aquaculture method produced in the process of modernization, enterprise and large-scale development of aquaculture industry, which realizes high-density, high-yield and high-efficiency fishery production. The intelligent aquaculture water quality monitoring system is oriented to the development needs of intensive, high-yield, efficient, ecological and safe aquaculture, based on Internet of things technologies such as intelligent sensing, wireless sensing network, communication, intelligent processing and intelligent control. The Internet of things system of aquaculture integrates the functions of online collection of water quality environmental parameters, intelligent networking, wireless transmission, intelligent processing, early warning information release, decision support, remote and automatic control.

Intelligent system of Aquaculture Environment

The intelligent system of aquaculture environment is developed to meet the development needs of intensive, high-yield, efficient, ecological and safe aquaculture, and is based on Internet of things technologies such as intelligent sensing, wireless sensing network, communication, intelligent processing and intelligent control. The Internet of things system of aquaculture integrates the functions of online collection of water quality environmental parameters, intelligent networking, wireless transmission, intelligent processing, early warning information release, decision support, remote and automatic control. Through information terminals such as mobile phones, PDAs and computers, farmers can grasp the environmental information of aquaculture water quality in real time, obtain abnormal alarm information and water quality early warning information in time, and automatically adjust the control equipment in real time according to the monitoring results of water quality. realize the scientific breeding and management of aquaculture, and finally achieve the goal of saving energy and reducing consumption, green environmental protection, increasing production and income.

Through the monitoring system in the monitoring center, aquaculture technicians can grasp the environmental information of aquaculture water quality in real time, obtain abnormal alarm information and water quality early warning information in time, and adjust the control equipment in real time according to the water quality monitoring results. realize the scientific breeding and management of aquaculture, and finally achieve the goal of saving energy and reducing consumption, green environmental protection, increasing production and income. Users can also grasp the water quality information and staff working conditions of farms distributed in different locations in real time through the network.

Water quality monitoring stations can choose to install dissolved oxygen sensor, pH sensor, water level sensor, salinity sensor, turbidity sensor, etc., together with intelligent data acquisition, mainly to achieve on-line collection, processing and transmission of water quality environmental parameters of the farm. The oxygen enrichment control station includes a wireless control terminal, a power distribution box, an air compressor and an aeration oxygen enhancement pipe (or aerator). The wireless control terminal gathers the information collected by the water quality monitoring station, according to the demand for dissolved oxygen of different breeds, the action of the oxygen enrichment equipment is controlled by the algorithm model. The site and the remote monitoring center include the WSN wireless access point and the field monitoring computer. The data collected by the wireless control terminal is collected to the field monitoring computer through the wireless access point. The user can query the water quality parameter data locally, at the same time, the monitoring computer analyzes and processes the data, makes the control decision, and sends 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 analyze and process the data, make control decisions, and remotely control the oxygen equipment. The aquaculture water quality on-line monitoring system includes high precision sensor probe (sensor), data acquisition and analysis terminal, wireless communication terminal, intelligent oxygen transmission control cabinet, intelligent mobile display terminal, Internet cloud server, online mobile terminal display and control software and other software and hardware facilities, which provides a strong scientific and technological backing for the information and intelligent realization of aquaculture. The system allows managers in related fields to view the sampling data of the probes of each monitoring station online. At the same time, it provides a short message prompt function, which makes it convenient for managers to know the parameters of water quality in time, so that managers can get the warning news of water quality problems at the first time. So as to take timely measures to avoid losses.

When the system is running, the data collected by RIU, such as dissolved oxygen and temperature, are transmitted to the WEB server through DTU in real time. The WEB server stores these data in real time and provides users with the function of querying at any time in the form of web pages. 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 user-designated mobile phone in real time through a text message, so that the user can know the water quality anytime and anywhere.

Finally, the editor of the industrial mining network gives you the popularity of the two most popular and popular water quality sensors, and they are all high-quality products imported from the United States. You know, the strict testing requirements of the United States in terms of export product quality are famous all over the world and are trusted by countries all over the world.
