Soil moisture monitoring system for soil moisture monitoring in regional farmland
Water-saving irrigation occupies a very important position in the development of China's agriculture. Considering the sustainable development of the national economy, the current task of water-saving irrigation planning is to study various engineering measures, control methods and methods that are technologically advanced and economically reasonable. , Reduce the useless loss of irrigation water; reasonably allocate water resources in time and space, and implement scientific irrigation decision-making and precise irrigation control methods in the field to achieve rational use of water resources and promote the sustainable development of agricultural efficient water-saving technologies . As an emerging agricultural water-saving technology field, the monitoring of farmland waterlogging during crop growth has received increasing attention. It integrates expert knowledge and experience and solves problems through computers. Soil moisture monitoring system can effectively monitor soil nutrients.
In the development of control hardware for precision irrigation systems, the controllable range of the system is large, and the versatility, standardization, and extensibility of the hardware are the key. The research and development of advanced wireless communication transceivers provide the hardware basis for large-scale regional irrigation group control. Due to the vast area of ​​irrigation, there is a wireless patrol center communication transceiver device in the central control room to complete the spatial transmission of many dynamic data collected on the site. The entire hardware system not only achieves information processing and processing and security information management under the wireless network carrier, but also controls the system independently. The control parameters are modified for wireless and on-line portability. There are not many lines to be laid and maintained. The system has a certain degree of fault tolerance. Local damage will not affect the entire system.
Soil moisture monitoring system in the entire farmland, facility soil moisture monitoring system, the system can not only provide regional irrigation decision data and the corresponding precision control mode, but also presets the common control mode, the user can easily select the desired mode. During the operation process, the user can freely set the control process according to his own needs, and set several irrigation groups to work in one or several groups to achieve arbitrary setting of farmland and facility system irrigation order, and complete the opening of any irrigation group in the region. Or close. Users can automatically complete farmland and facility irrigation according to the set time sequence, and start the preset irrigation work schedule at regular time. After the system completes the irrigation workflow, the user can save the control flow that he has set for reuse, and does not need to be set before each job. Computer system operation platform working status icon and real-time status of irrigation site to achieve tracking and synchronization.
