The Design And Implementation Of The Provincial Automatic Soil Moisture Detection System Based On Wireless

With the progress of society and the development of science and technology, especially since the 18th century Industrial Revolution, the capacity of human in exploiting natural resources increased continuously, meantime, the fuel consumption increased sharply. During this time, a large number of underground mines are exploited and smelted and the industry is highly developed. On one hand it can promote the development of industry and agriculture greatly; however, human activities cause dramatic changes in climate and the frequent weather disasters, which include storm floods, droughts, tropical cyclones, frost and low temperature freezing damage, hail, rain and fog and even sandstorms and other disasters. Shandong is a major agricultural province, and drought is one of the major meteorological disasters which caused agricultural production dropped. Soil moisture is the main factor for crop growth, as its conditions impact crop growth and yield greatly. The traditional method of borrow is time-consuming, poor-represented, long-cycled, Inefficient and cannot meet the needs of modern agricultural services.This paper gives a detailed study to the provincial radio-based automatic soil moisture monitoring system from three aspects:the system functional requirements, non-functional requirements and system construction feasibility of Shandong Province. It also analyzes the current situation at home and abroad of soil moisture monitoring and discusses the development and contrast of soil moisture detection technology and wireless communication technology in depth. The article describes detailed from three parts of hardware design, communication network design and software design. The part of hardware includes the observation site, equipment and instruments composition and application principle. The part of communication network includes network design and architecture section and implementation process. The part of software includes the design and function modules complement of provincial automatic soil moisture central station based on C/S structure and the network platform display of soil moisture monitoring based on B/S structure. It focuses on the design and implementation of the various systems of data processing, remote control, manual processing and real-time monitoring of soil moisture and other provincial automatic central station modules design. At the same time it shows the data query, browse, download, statistical analysis and other functions of automatic soil moisture monitor network platform.The construction and completion of this system makes the soil moisture observations in Shandong Province achieve a qualitative leap from manual operations to the detection process through automated detection equipment and real-time detection of wireless transmission. The intensive storage management of the high-frequent, high-perceive and multi-site large data enables users to obtain the required data elements and associated data analysis chart in real time via the meteorological network. At present the province’s 123 counties have been completed several of observation sites which have provided important data support for the agricultural production and disaster prevention and mitigation in our province and have provided quality meteorological services for the majority of farmers. It will also enhance the ability and level of social services greatly.
