Remote Acquisition and Management System of Information on Crop Water Requirement

Abstract

Irrigation time and irrigation intensity is determined by manual observation and experience in traditional irrigation, which would cause waste of water resources. In addition, there is a serious shortage of labor, and no one wants to collect information in the field. In view of the above situation, a remote acquisition and management system of crop water requirement information based on Internet of Things(IoT) technology is proposed in this paper. The system includes an information collection module, a wireless transmission module, and a host computer. The information collection module acquires soil moisture information by collecting the soil moisture sensor and the environmental information collected by the small weather station (wind speed, rainfall, temperature, humidity)in real time; the wireless transmission module sends the data collected by the information collection module to the server for analysis and processing in real time. C# language programming is applied to read, convert, store, and display real-time data stored in peripheral data sources through digital radio stations and wireless bridges in this paper. By using Visual Studio 2013.NET programming, the upper computer designs the monitoring interface of the system host computer, which could not only do real-time detection and storage of soil and environmental parameters, but also could do analysis and management of crop water demand status and draw curve. Experiment results show that: the functions are working well and the fault tolerance mechanism is favorable; the system proposed in this paper improves the stability of data collection; by realizing remote access to the crop growth environment in real time, manpower and material resources could be greatly saved and labor intensity could be effectively reduced. saving manpower and material resources and effectively reducing labor intensity.
