Research And Implementation Of Facility Crop Monitoring System Based On Modbus/UDP

In recent years,China has proved its’ capability in the development of agriculture and facilities.The vigorous development in agriculture is conducive to alleviating the shortage of land resources and to ease the stress by the growing vegetable demand of people.The improvement of facility agriculture has become an important indicator to measure the agricultural modernization level of a country.At present,however,the agricultural facilities and equipment are outdated with backward technological means,and the capabilities of environmental monitoring and regulation system are difficult to meet actual requirements.In this paper,the Modbus communication mode is studied during data transmission.The UDP transmission protocol is compared and analyzed.Based on the Android platform,the.NET MVC+HTML5+EasyUI method is used to design the facility crop monitoring system,which realizes the data collection,transfer and management functions during the growth process of the facility crop.The realization of the system can effectively improve the crop yield of facilities,reduce environmental pollution,and make an effective attempt to explore a path for the development of facility agriculture featured by high-quality,high-yield and sustainable development.The specific research contents are as follows:(1)The Modbus protocol communication is studied.Taking the advantages of the Modbus protocol,the optimal transmission scheme between the internal wireless sensor and the collector is determined,and the data transmission mode between the sensor and the collector is realized,ensuring that the data can be transferred to the collector according to the demand.(2)The UDP transmission protocol is studied.The UDP transmission protocol and GPRS are used to realize the digital transmission mode between the collector and the server.The format and specification of the GPRS-based UDP transmission are designed to realize the communication and transmission between the collector and the server,so as to ensure that all the data can be transferred to the server quickly and accurately.(3)The paper studied the technology such as.NET,adopted the methods of.NET+HTML5+EasyUI and encapsulation,designed the facility crop monitoring system based on Android platform,realized the real-time monitoring function of relevant environmental factors,so as to achieve a system that is of high efficiency and low error.
