1. Industry background
When the Internet of Things has not had any impact on agricultural applications, most of China's irrigation operations are still in the traditional irrigation mode, using flood irrigation, low irrigation efficiency and serious waste of water; personnel need to visit the site to check the irrigation situation, which requires a lot of manpower and time-consuming . The lack of scientific data in the entire irrigation process led to arbitrary irrigation water, fertilization, low water and fertilizer utilization, and waste of resources. Long-term randomness also breeds agricultural planting problems such as soil structure destruction and environmental pollution.
In addition, agricultural production is basically in relatively remote areas and the crop planting area is large, making manual monitoring difficult. With the expansion of wireless signal coverage and the rapid development of Internet of Things technology, the application of Internet of Things in agriculture is also common. For example, the use of Internet of Things to make farmland irrigation using wireless communication technology to control irrigation has become a new irrigation method, and has received strong support from the state.
The Ministry of Agriculture and Rural Affairs “Notice on Assigning Farmland Construction Tasks for 2019” pointed out that under the guidance of the socialist ideology with Chinese characteristics in the new era, the Central Rural Work Conference and the State Council ’s winter and spring farmland water conservancy infrastructure construction video and telephone conferences were fully implemented to ensure national food security The overall requirements, improve the high-standard farmland construction planning system and related policies, strengthen capital integration, establish a multi-funding mechanism, increase capital investment, accelerate the construction of high-standard farmland, develop high-efficiency water-saving irrigation, and play a leading role in the demonstration of major projects To implement regionalized overall construction, establish a regular scheduling system, strengthen project management, strengthen supervision and evaluation, achieve rewards and punishment for disadvantages, and ensure that more than 80 million mu of high-standard farmland is added in 2019, and simultaneously develop an efficient water-saving irrigation area of 20 million mu. To lay a solid foundation for ensuring national food security.
Second, the solution
The agricultural water-saving irrigation system adopts the principle of adapting to local conditions, chooses different irrigation facilities according to different needs of different regions and different crops, and uses sensor technology, 4g technology, lora wireless communication technology, and big data processing technology to monitor and manage farmland irrigation. To ensure that the water needed for crop growth is met at the right time in order to achieve the purpose of water-saving irrigation.
Agricultural water-saving irrigation system is mainly composed of soil moisture sensor, meteorological monitoring station, valve and pump control, video, acquisition control terminal, wireless communication module, photovoltaic power system and agricultural management monitoring platform. The system integrates information such as hydrology and water conditions, meteorological crops, and construction conditions in the area to realize the functions of information collection, statistics, analysis, control, and scheduling. Provide scientific decision-making basis for irrigation district management department, improve irrigation district management efficiency, and realize agricultural irrigation automation.
Three, program advantages
1. Get energy locally and run forever
The system's power supply system uses a combination of solar + lithium battery to provide long-lasting and stable power output. In addition, the entire system is designed with low power consumption, which can ensure that it can run in the absence of light for many days.
2. Flexible networking, convenient construction
According to the on-site situation, the monitoring equipment, the control equipment and the collection and control terminal can be wired or Lora. The collection and control terminal and the wireless communication module are connected by wire. The wireless communication module uploads the data to the agricultural management monitoring platform through 4G. The wireless communication module has the characteristics of anti-interference and strong stability. The Lora networking scheme can cover a range of 10KM in diameter, which can reduce problems such as field wiring difficulties.
3. Intelligent platform
The agricultural management monitoring platform presents the monitoring results in an intuitive way. Users can understand the water level, flow, rainfall and other information in real time, summarize and analyze the data, and generate data reports; they can complete the query, statistics and analysis of historical data. Through the platform, quantitative irrigation, scheduled irrigation and on-demand irrigation can also be achieved.
4. Mobile monitoring
Through the mobile phone APP, the location information and monitoring values of each monitoring point can be viewed, and real-time monitoring images on site can also be retrieved.
4. Industry Application
The agricultural water-saving irrigation system has monitoring and control functions, and at the same time integrates meteorology and water regime monitoring into one, providing data support for irrigation operations and scientifically guiding the rationality of irrigation operations. The system has many functions such as automatic irrigation, automatic rotation irrigation, on-demand irrigation, and intelligent decision-making. It can not only meet the needs of agricultural field irrigation, but also be used for urban greening, park greening, and other scenarios. Farming irrigation that is more efficient, economical and efficient.
