4G technology helps agricultural Internet of Things construction
The Smart Agricultural IoT Cloud Platform solution combines the most advanced IoT, cloud computing, sensors, automatic control, etc., and displays the temperature, humidity, PH value, light intensity, etc. of greenhouses, fields, greenhouses, etc. in real time on the browser or mobile client. CO2, or as an automatic control parameter, participates in the automatic control to ensure that the crop has a good and suitable growth environment. Including greenhouse greenhouse intelligent monitoring system, underground pipe salt monitoring system, field irrigation / drip irrigation / wheel irrigation system, agricultural products e-commerce platform, water and fertilizer integration system.
the pilot province of agricultural internet of things in the country. It has
taken the lead in launching the first batch of 13 pilot demonstration counties
and 50 demonstration sites in the country. In Wuzhou, Anhui Province, the
birthplace of China's rural reform, Anhui Mobile cooperated with the local
government to carry out the pilot project of agricultural Internet of Things,
using the characteristics of high bandwidth and high speed of 4G network,
focusing on the application of agricultural Internet of Things technology,
cultivating multiple sample projects and promoting The demonstration and
promotion of agricultural Internet of Things has achieved good results.
The Ganzhou Agricultural Internet of Things Construction Project focuses on the Quanjiao County Agricultural Internet of Things Integrated Service Platform and builds 50 application demonstration sites throughout the city, covering vegetable facility agricultural applications, large-scale animal husbandry applications, aquaculture applications, grain and oil production and processing applications, Fruit planting application, Chinese herbal medicine application, seedling production application, crop “four emotions” monitoring 8 areas, integrated production environment real-time monitoring, production equipment remote control, agricultural product quality traceability, disease expert diagnosis, agricultural production warning, agricultural e-commerce, farmers Distance education and training 7 functions to achieve construction goals that can be seen, available, and promoted.
Relying on the Internet of Things to accelerate the transformation and upgrading of agriculture. In the process of building the agricultural Internet of Things, Anhui Mobile and Chenzhou City have strengthened cooperation, focusing on the four leading industries of aquaculture, livestock and poultry breeding, facility vegetables and high-quality grain, focusing on practical problems in agricultural production, management, management and service. The construction of a good agricultural Internet of Things platform, demonstration counties and demonstration enterprises will promote the application of agricultural Internet of Things technology in the city in an orderly manner, improve the level of precision and intelligence of agriculture, and promote the transformation of rural industries and the transformation of agricultural development methods. At present, the construction projects of 50 IoT application demonstration sites are progressing in an orderly manner. All the websites of the agriculture-related departments have been integrated, and the overall access to the agricultural Internet of Things integrated service platform has been fully put into use. It has covered more than 400,000 households and the total output value. 3.75 billion yuan, plans to complete the agricultural sector and agricultural enterprises at all levels in the city by 2020, and the agricultural Internet of Things application pattern in several areas including planting and aquaculture and deep processing of agricultural products.
Increase information to benefit the people and promote farmers to increase production and income. Anhui Mobile makes full use of the advantages of 4G network and resources, relying on the application of Internet of Things technology to help farmers achieve professional and precise agricultural production management, and truly realize information to benefit the people. In the modern aquatic product base of Quanjiao County, Anhui Mobile realized the real-time display of water quality and environmental parameters such as dissolved oxygen, PH value, water temperature and water level and surrounding conditions by deploying water quality monitoring, water level water temperature sensor and smart camera in the fish pond. The farmer can control the aerator, the feeding machine and other feeding equipment through the on-site equipment and network terminal to control the timing, automatic and SMS. According to the actual measured data at the demonstration site, the local agricultural committee used the mobile ADC management platform to send mobile phone text messages to more than 1,000 large aquaculture households in Quanjiao County to provide farmers with weather forecast-type aquaculture water quality forecasting and warning services to help farmers achieve increased production and income.
Establish a normalized collaborative working mechanism. Anhui Mobile, in conjunction with the status quo of local agricultural Internet of Things construction, actively contacted local government commissions, the Economic and Information Commission, the China Merchants Bureau and other government departments to focus on issues such as IoT development planning, preferential policies, infrastructure construction, capital investment, and technology applications. Promote the development of IoT technologies, industries and applications with regional characteristics according to local conditions, promote the sharing and sharing of communication infrastructure, sensing infrastructure, computing and storage infrastructure across industries, and form synergies among government departments, industries and communication operators to promote Ganzhou The agricultural Internet of Things construction project is in an orderly and healthy development.
In the practical application of the agricultural Internet of Things, there are also many difficulties. Due to factors such as scattered agricultural production, low degree of organization, and low added value of agriculture, large-scale promotion of agricultural Internet of Things is difficult, which restricts the further expansion of the industrial scale. The author suggests that operators should actively recommend to the government departments to establish a package of support policies including fiscal, taxation, finance, scientific research, talents, land, facilities, and comprehensive information services, encourage social funds to invest in the agricultural Internet of Things industry, and mobilize the main body of the parties. The enthusiasm of networking technology has gradually formed a commercial operation mode of agricultural Internet of Things (the government leads, the market operates, the parties cooperate and promote together).
