Abstract
Precision agriculture is the trend of modern agriculture, and it is also one of the important ways to realize the sustainable development of agriculture. In order to meet the production requirements of precision agriculture—efficient use of agricultural resources, and improving the crop yields and quality—some necessary field information in crop growth environment needs to be collected and monitored. In this paper, a farmland information collection system is developed, which includes a portable farmland information collection device based on STM32 (a 32-bit comprehensive range of microcontrollers based on ARM Crotex-M3), a remote server and a mobile phone APP. The device realizes the function of portable and mobile collecting of multiple parameters farmland information, such as chlorophyll content of crop leaves, air temperature, air humidity, and light intensity. UM220-III (Unicore Communication Inc., Beijing, China) is used to realize the positioning based on BDS/GPS (BeiDou Navigation Satellite System, BDS/Global Positioning System, GPS) dual-mode navigation and positioning system, and the CDMA (Code Division Multiple Access, CDMA) wireless communication module is adopted to realize the real-time remote transmission. The portable multi-function farmland information collection system is real-time, accurate, and easy to use to collect farmland information and multiple information parameters of crops.
Highlights
With the continuous development of information technology, it is used to realize the transformation of traditional agriculture to the precise and intensive informationized agriculture, which is system engineering used to maintain the sustainable development of agriculture and is the tendency in modern agriculture technology
This paper firstly introduces the composition of the farmland information collection system, which consists of three parts of the farmland information collection device, the remote server, and the mobile phone app
The system scheme of farmland information collection system is shown in Figure 1, which is composed of three parts, including the farmland information collection device, the remote server and the mobile phone app
Summary
With the continuous development of information technology, it is used to realize the transformation of traditional agriculture to the precise and intensive informationized agriculture, which is system engineering used to maintain the sustainable development of agriculture and is the tendency in modern agriculture technology. The application of information technology in agriculture is bound to be one of the key research areas in modern agricultural engineering. With the development of electronics and communication technologies, the new generation of information technology represented by 3S (GIS, GPS, and RS), Internet of things, cloud computing, and big data has been widely used in all kinds of agriculture fields, which promotes the development of agricultural modernization [1,2,3,4,5,6,7,8,9]. The collection, transmission, storage, and processing of farmland information are the basis of the development of modern agriculture. Du et al [2] proposed an approach to evaluation of the agricultural environment from on-farm sites to regional scales, and designed a regional-scale monitoring system by integrating with the spatial analysis technology of WebGIS
