[China Agricultural Machinery Network Industry News] Since the reform and opening up, China's agricultural development has achieved remarkable results, and the grain output has increased by 12, and the per capita possession of vegetables, fruits, meat, eggs and aquatic products is also among the highest in the world. But it is expensive. First, the abuse of chemical fertilizers and pesticides, over-exploitation of groundwater resources and excessive consumption of soil fertility, leading to deterioration of the ecological environment, food safety issues are prominent; second, extensive management, resulting in agricultural competitiveness is not strong, there is agricultural production increase, import increase and inventory increase " The phenomenon of three-volume increase, more and more low-end agricultural products are slow-moving. To solve these problems, we need to vigorously develop smart agriculture that uses advanced technologies such as smart devices, Internet of Things, cloud computing and big data as the main means. Smart agriculture promotes the transformation and upgrading of the agricultural industrial chain. 
The development of smart agriculture in Jiangxi Province aims to realize the “four modernizations†such as intelligent agricultural production, e-commerce, management, and service convenience, and promotes next-generation information technology and agriculture such as mobile Internet, cloud computing, big data, and Internet of Things. Production, management and management services will be integrated and developed, innovative agricultural product circulation channels will be realized, agricultural management will be transparent, agricultural information services will be promoted into the village, and a new information-based pattern will be established to support the development of modern agriculture and urban-rural integration.
Jiangxi Province allocates 30 million yuan to build "smart agriculture"
In 2016, Jiangxi Province's financial integration related agriculture-related funds of 30 million yuan specifically supported the province's smart agriculture construction, focusing on the operation and maintenance of the 123 N platform, the construction of agricultural big data centers, the construction of agricultural products e-commerce system, and the construction of demonstration centers. Strive to make the agricultural informatization level of Jiangxi Province exceed 60% through five years of efforts.
Developing smart agriculture: national capital investment and guidance are indispensable
The development of smart agriculture in Jiangxi Province aims to realize the “four modernizations†such as intelligent agricultural production, e-commerce, management, and service convenience, and promotes next-generation information technology and agriculture such as mobile Internet, cloud computing, big data, and Internet of Things. Production, management and management services will be integrated and developed, innovative agricultural product circulation channels will be realized, agricultural management will be transparent, agricultural information services will be promoted into the village, and a new information-based pattern will be established to support the development of modern agriculture and urban-rural integration.
The construction of smart agriculture in Jiangxi Province will focus on creating “123 Nâ€, namely: building “1 cloud terminal†– Jiangxi Agricultural Data Cloud; “2 Centers†– Jiangxi Agricultural Command and Control Center, Jiangxi 12316 Information Service Center; “3 Platforms - Jiangxi Agricultural Internet of Things Platform, Jiangxi Agricultural Products Quality and Safety Supervision Traceability Platform, Jiangxi Agricultural Products E-Commerce Platform; "N Systems" - involving agricultural production, project management, fund supervision, comprehensive law enforcement, administrative approval, market information , agricultural technology services, government offices and other subsystems. The “Smart Farm†project will be implemented. By 2020, there will be more than 100 demonstration enterprises with the application of agricultural Internet of Things technology as the core. The “Baixian Baiyuan†modern agricultural demonstration park will basically realize the application of Internet of Things. By 2020, the rural e-commerce model such as the Yinong Information Agency basically covers most of the administrative villages in the province, and the comprehensive level of agricultural informatization with the application of agricultural information technology is 53%.
Developing smart agriculture, capital investment is a big problem
Capital investment is the primary issue in the development of the agricultural Internet of Things. The construction of agricultural IoT infrastructure has the characteristics of large one-time investment and long return period. In the case of low overall efficiency of agriculture and the decentralized operation of small farmers, many Internet of Things equipment is difficult to promote on a large scale due to high prices. It is understood that a set of Internet of Things equipment, due to its core sensors, prices range from 10,000 yuan to several hundred thousand yuan. If it is not engaged in scale management or aquaculture, farmers who grow large fields are unable to afford it.
"The lack of special sensors for agriculture is the bottleneck of the development of agricultural Internet of China. At present, the number of agricultural sensors in China is less than 10% of the world, the localization rate is low, and the market scale effect is lacking. There is still much room for improvement in terms of coverage and applicability. Li Changjian, director of the Information Center of the Ministry of Agriculture, said that China's sensors mainly focus on monitoring temperature and humidity, and pay less attention to other environmental factors, especially the perception of biological ontology. The performance of the domestic sensor is not stable enough, making the monitoring data inaccurate, often requiring correction, and the equipment has a short life.
At the same time, IoT equipment is not enough to meet the "ground gas", and we must continue to explore in meeting the needs of farmers. At present, China's agricultural IOT equipment is mainly produced in the laboratories of colleges and universities, with many conceptual products, the actual industrialization rate is not high, and the laboratory theory research and agricultural practical application are quite different.
“Internet of Things equipment should strive for convenience and “fooling.â€â€ Professor Li Daoliang, head of the Yixing Agricultural Internet of Things Research Center of China Agricultural University, said that Yixing Aquaculture Internet of Things has developed from laboratory concept products to mature application systems. In the 3rd generation products, the three modules of circuit, communication and model have been improved hundreds of times in total, and most of them are improved to adapt to the local environment and the simple operation of farmers.
Control costs and accelerate technology development
According to reports, the Ministry of Agriculture is actively planning to launch the “Yi (e) Agricultural Plan†with the support of the Ministry of Finance, and systematically promote the construction of the national agricultural production and management information and information service system. At the same time, it is studying the establishment of an agricultural information subsidy system, accelerating the promotion of agricultural Internet of Things related products and equipment into the agricultural machinery purchase subsidy catalogue, in order to encourage the enthusiasm of telecom operators, IT-related agricultural enterprises, research institutes and other social forces, and gradually form the government. The diversified investment entities under the guidance, marketization of operation and maintenance, and joint efforts to promote the development of agricultural Internet of Things.
Zhao Chunjiang, director of the National Agricultural Information Technology Research Center, said: The Agricultural Internet of Things is a complex project. It is generally in the experimental stage. It should not only pay attention to it, but also blindly exaggerate its role. It should be combined with the existing informationization work. The development and application of the Internet of Things should focus on the key points, and it is necessary to give priority to industries with good foundation and high scale. Priority should be given to the development and utilization of land and water resources, fine management of production processes, and agricultural products and food safety monitoring systems.
Facing the development status of domestic sensors, relevant experts said that it is necessary to adhere to independent research and development and import and absorption. To enhance the independent innovation capability of the agricultural Internet of Things, the difficult technology should be accelerated to introduce and absorb. The short-and-fast technology should be independently researched and developed, and the sensors should be converted into low-cost, portable instruments and equipment. Through single technology breakthroughs and integrated applications, technology development and application should be accelerated. pace.
The so-called "smart agriculture", popular point of view is to install a sensor control system in the greenhouse, farmers can remotely view and control the light, temperature, soil moisture and other indicators in the greenhouse remotely through the computer or mobile phone; at the same time, the system can also Pre-set parameters automatically adjust the environmental indicators in the greenhouse. With only one mobile phone in the whole process, it is easy to get the vegetable planting, which completely changed the traditional agricultural labor mode of “facing the loess back to the sky and sweating like mudâ€.
But this smart agriculture is good, but it has not grown in most parts of China. First, the financial constraints are serious; second, the lack of agricultural sensors; third, the equipment is not connected to the "ground gas." At present, most agricultural IoT products are R&D products, and the cost is high. It is necessary to encourage large-scale IT operators to enter the industry. It is also hoped that agricultural IoT products can be incorporated into the agricultural subsidy sequence to promote the development of this industry. That is to say, wisdom agriculture is generally a process of top-down reform initiated by the government. In the absence of basic information and technology, farmers need government support and guidance. With the advancement of science and technology, information technology and intelligent agricultural equipment such as Internet of Things, mobile internet, 3S and other fields are increasingly applied in the field of agricultural production. After a few years, smart agriculture will spread all over the fields of hope.
The five most common types of car sensors parts:
1. Throttle position Sensor
The throttle position sensor is mounted on the throttle door to detect the throttle opening. It is connected with the throttle gate through the lever mechanism, and then reflects the different working conditions of the Engine Auto Parts. This sensor can be detected in different operating conditions of the engine input electronic control unit (ECU), so as to control the different fuel injection volume.
2. Inlet pressure sensor
The inlet pressure sensor can measure the absolute pressure in the intake manifold according to the load state of the engine, and convert the electrical signal and the rotational speed signal into the computer as the basis for determining the basic fuel injection quantity of the injector.
3. Crankshaft Position Sensor
Computer-controlled Ignition System is the most important sensor, its role is to detect the top stop signal, crank angle signal and engine speed signal, and input into the computer, so that the computer can be in the ignition sequence of the cylinder issued the best ignition time instructions.
4. Air Flow sensor
Air flow sensor is to convert the inhaled air into electrical signals sent to the electronic control Unit (ECU), as a decision to fuel injection of one of the basic signals.
5. Knock Sensor
The detonation sensor is installed on the cylinder of the engine to monitor the detonation of the engine at any time. At present, there are two kinds of resonant and non resonant type!
The car sensor is the input device of the automobile computer system, it transforms the information of various working conditions, such as the speed, the temperature of the medium, the engine running condition, into the electric signal to the computer, so that the engine is in the best working condition. Car sensors are many, to determine the fault of the sensor, should not only consider the sensor itself, but should consider the entire circuit failure.
