In the hottest agriculture, the sensor is difficul

  • Detail

Sensors in agriculture are difficult to expose the natural environment, and the maintenance cost is high

through the information system in the computer, you can know the temperature, humidity, carbon dioxide concentration and soil composition in the vegetable greenhouse, and you can water, ventilate and fertilize the greenhouse with the click of the mouse... The application of true agricultural IOT should be oriented to large areas of outdoor fields, not limited to the greenhouse. Through the information system in the computer, we can know the temperature, humidity, carbon dioxide concentration and soil composition in the vegetable greenhouse. With the click of the mouse, we can water, ventilate and fertilize the greenhouse. The real application of agricultural IOT should be oriented to a large area of outdoor fields, not limited to the greenhouse

at present, the conditions for using IOT technology in large areas of farmland are not mature. The field environment such as temperature, humidity and carbon dioxide concentration can only be monitored but not controlled. We cannot effectively change the field environment. Bosvi, vice president and Secretary General of China IOT Industry Association, said in an interview. In addition, the construction cost of IOT infrastructure is high, and the input-output ratio is not high for ordinary crops in the field. Wang Huan, general manager of CCID Consulting semiconductor industry research center, told reporters that the European Commission listed graphene as one of the "flagship projects of emerging technologies in the future": temperature and humidity sensors, carbon dioxide sensors, etc. are expensive, and various equipment are exposed to the natural environment, so the maintenance cost is very high, which is not applicable to ordinary crops. IOT is applicable to crops that are not highly cost sensitive, such as * * agricultural products

the biggest problem at present is that people do not quantify the application of IOT technology in agriculture in economic indicators. The demonstration without cost has no practical value for the promotion of agricultural IOT. Boswell's words broke the crux of the current obstacle to the development of agricultural IOT. The application of agricultural IOT technology should be based on improving the output and output value per unit area and bringing economic benefits to farmers. Only in this way, a large number of enterprises and investment institutions will flow into this field, and the industry can develop healthily and rapidly. But at present, many application demonstration projects are mere formality

in addition to the conceptual problems and the above uncontrollable factors of cost and environment, the current mode of decentralized management of rural land is not suitable for the promotion of IOT technology. In an interview, Li Yan, director of the science and Technology Department of the smart city research center of the China Academy of urban development and executive president of Beijing shengyanxun Technology Development Co., Ltd., threw aside his own experience in doing projects: if there were special departments to uniformly plan and manage large areas of agricultural land, the promotion of IOT would be relatively easy. At present, in most areas, if people want to use IOT technology, they can only buy equipment and use it alone, which does not reflect the role of IOT. So we chose a few areas that can manage agricultural land in a unified way as the project

as IOT application is a new application mode, hot rolling, double stand tandem cold rolling and supporting stretching, aging, continuous withdrawal and other supporting equipment are added in the reserved plant. In its development process, it is bound to encounter many problems. In addition to the above factors, the performance of some equipment used in current agricultural IOT applications is far lower than expected. Houfangyu, the founder of China M2M industry alliance, accepted mining 2 The oil pressure system has serious oil leakage. The interview said: the application environment of agricultural IOT is relatively poor, and many sensors can not meet the needs of agricultural applications. For example, the technology of soil moisture sensor and leaf surface analyzer for agriculture is relatively immature, and some domestic products often fail in the application process, which also makes it difficult to promote the application. In addition, the immature industrial system, such as various enterprises acting in their own ways and different access standards at the perception layer, also hinders the development of the whole industry
