System for automatic collection and management of farmland experimental data

Abstract

The invention discloses a system for automatic collection and management of farmland experimental data. The system comprises: a presentation layer, which is used to receive requests or instructions that a user submit or issued through a browser and to call a business logic processing module corresponding to a business logic layer by processing the user's requests so as to achieve interaction with the business logic layer, and is also used to encapsulate data into a data model; a business logic layer, which is used to respond to and process the user service requests from the presentation layer and to return the process results to the presentation layer so as to present the user, and is the link between the presentation layer and a data layer; the data layer, which is used to receive the process results of the business logic layer, is responsible for data storage and retrieval and provides the data to the business logic layer, wherein the business logic layer feeds the data back to the presentation layer in response to the user's requests. The invention realizes the functions of collecting, querying, statistically processing, analyzing, inputting and outputting the farmland experimental data and also managing and sharing the collected test data uniformly.

Description

technical field [0001] The invention relates to the field of information agriculture, in particular to an automatic collection and management system of farmland experiment data. Background technique [0002] my country is a large agricultural country. Over the past 60 years since the founding of the People's Republic of China, 22% of the world's population has been fed with 7% of the world's arable land, and agricultural development has made remarkable achievements. However, with the growth of population and the steady development of economy, the consumption of agricultural water continues to increase, and the serious shortage of water resources has become one of the main factors restricting the development of agriculture in our country. For example, due to the low agricultural water productivity in my country, the water productivity of irrigated agricultural food crops is less than 1kg / m 3 , the agricultural area of ​​dry land accounts for about 60%, and its water producti...

Problems solved by technology

For example, due to the low agricultural water productivity in my country, the water productivity of irrigated agricultural food crops is less than 1kg / m 3 , the agricultural area of ​​dry land accounts for about 60%, and its water productivity is only 0.3kg / m 3 -0.4kg / m 3

However, there are many problems in the collection, processing and control of soil moisture and other data.

For example, most of the traditional soil moisture collectors use analog sensors to transmit data to PCs through analog-to-digital conversion and serial communication. However, environmental factors such as high humidity and strong light in the farmland test area make the installation of PCs relatively expensive. high

And due to the harsh environmental conditions on site, the aging speed of the PC is increased

In addition, the transmission rate of serial communication is limited, which increases the difficulty for soil moisture monitoring
