System of Data Acquisition and Detection for Automatic Irrigation

摘要

It is important to adopt changes in agricultural practices and employ innovative ideas for the agricultural industry to maintain its current rate of production. As for acquiring soil, crop and environmental variables of precision agriculture, the real-time, robust, low-cost acquiring data system is indispensable. Sensor technology can be used to study soil dynamics based on information gathered at regular intervals, and the data collected can be used as feedback to improve irrigation efficiency. Wireless sensor network (WSN) technology development is driven by its use in different applications. Data acquisition and detection in precision agriculture is an area of significant research in the field of wireless sensor networks (WSNs). The coordination of control and instrumentation data is most effectively managed using data networks and low-cost microcontrollers. In the past few years, many WSNs had been deployed. These applications serve to explore the requirements, constraints and guidelines for general sensor network architecture design. In near future, sensor networks will be an integral part of our everyday life. Sensor networks will be an integral component in most industries. For example, sensor networks could provide precise information about crops with respect to the soil quality and water content, enabling better irrigation schedules, pesticide usage and enhancing environment protection. Aim at automatic irrigation, this paper analyzed the condition of development about system of data acquisition and detection for automatic irrigation in China, especially in Xinjiang, northwest of China and analyzed the application of WSNs in precision agriculture. We discussed about problem of starve for on system of data acquisition and detection for automatic irrigation from aspect of application on agriculture irrigation. The barriers for development and adoption of automation technology for this system are also pointed out.
