Internet of Things greenhouse greenhouse construction and application of the role of agricultural modernization
Agricultural informatization is the basis and an important part of informatization of national economy. It is an important means to plan urban and rural areas and promote the development of agricultural economy. The construction of agricultural informatization has always been the top priority of the national work. Internet of Things technology is another information revolution after computer, Internet and mobile communication network. IoT technology applied to the field of facility agriculture, facility agriculture has a broader perspective. Attention and research on the needs of customers for IoT technologies will help IoT technologies to better integrate with the agricultural markets of facilities and achieve win-win results. The Role of Informatization in Agricultural Modernization Information services need to be diversified. Farmers need market information as well as information on new technologies and new achievements. They also need extension workers to help with decision analysis and actual production and management issues. This puts higher demands on the quality of rural extension workers. They not only provide agriculture Technology or achievements, but also to help farmers make scientific decisions and provide technical services that are compatible with the whole process of agricultural production and management to help farmers realize their incomes, affluence and rural comprehensive development. Information services also need personalization. Currently, planting large need seed sources, seed prices, planting environment and other information, and such a large planting has its own individual needs. For ordinary farmers, they have the technology of production management. For example, large growers planting tomatoes have a need for tomato cultivation and production management. Liquidity of information services, low cost requirements. Now pay attention to low-cost agricultural production, agricultural production and distribution of users more scattered, how to provide information services anytime, anywhere low-cost way, then the need for information technology promotion. Each specific agricultural extension activities, content and methods of effective combination is the key to the success of the promotion work, but also affect the efficiency of the promotion of the main factors. Promotion Content × Promotion Method × Audience Acceptance Ability = Promotion effect, from this formula can be seen as the method and content are equally important, only to achieve a reasonable mix in order to achieve the best results. In the process of improving the efficiency of promotion, information technology has changed our lifestyles relatively. The contents of promotion should be digitized and the means of information promoted so as to greatly promote the promotion efficiency. The way of agricultural technology promotion will gradually change farmers' cognition, and from understanding and understanding of adopting new technologies to promote the diffusion of technologies, the whole process needs information technology to support it. In other words, information technology supports the modern agricultural technology extension system. At present, the rural informatization in our country has entered a period of rapid promotion. Since the reform and opening up for 30 years, our country has gradually entered the ranks of low- and middle-income countries from low-income countries. Agricultural and rural areas have been leapfrogged. In 2015, the per capita income in agricultural areas 6977 yuan, equivalent to more than 1,000 US dollars. Former Soviet scholars have suggested that when the average per capita of 1,000 US dollars, the information will show a strong demand. At present, China's agriculture is facing a shortage of resources, ecological deterioration, labor shortage, food safety pressures, the need to substantially increase land productivity, labor productivity and resource utilization. Therefore, there is an urgent need to upgrade traditional agriculture with information technology and equipment technology, to change the mode of development and to raise the level of agricultural modernization. This is an objective requirement of our agriculture.
Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.
First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.
Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.
Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
