The major project "Key Technologies for Global Quantitative Remote Sensing Quantitative Monitoring of Large-scale Crops" in the field of Earth Observation and Navigation Technology in the field of Earth Observation and Navigation Technology undertaken by the Institute of Remote Sensing and Digital Earth, Chinese Academy of Sciences Inversion methods and product production have constructed a new global remote sensing quantitative monitoring system for bulk crops. For the first time, the Chinese and English bilingual "Global Agricultural Remote Sensing Quick Report" has been released globally, providing the international community with access to information on the food production situation. The subject passed the mid-term inspection organized by the National Remote Sensing Center of the Ministry of Science and Technology on December 25, 2013.
According to reports, on the basis of making full use of the remote sensing data of domestic meteorological satellites (FY-2 / 3) and environmental satellites (HJ-1), the research group independently developed a series of crop remote sensing monitoring indicators and evaluation methods, some of which are the first It has been used for global agricultural assessment, and has constructed a new multi-level, multi-index global remote sensing monitoring technology system for bulk crops. The relevant results have been incorporated into the annual report system of global ecological environment remote sensing monitoring promoted by the Ministry of Science and Technology, and on November 20, 2013 The "Global Agricultural Remote Sensing Newsletter" was published in Chinese and English for the world. The English version of "Global Agricultural Condition Remote Sensing News" is the first global agricultural condition monitoring information released by China to the world.
This subject is one of the major projects of the 863 Program "Synthetic Quantitative Remote Sensing System and Application Demonstration of Satellite-to-Earth". The project as a whole overcomes satellite-ground collaborative observation and satellite networking, multi-scale spatio-temporal remote sensing data rapid quantitative process processing and comprehensive quantitative remote sensing On the basis of key technologies such as product generation, research and development of special information products for remote sensing quantitative monitoring of bulk crops and research on remote sensing monitoring technology of crop planting area and output for global scales, to form independent and fast global bulk crops (wheat, corn, rice, soybeans) ) Quantitative remote sensing monitoring technology system for planting area and yield to meet the global monitoring and strategic needs for food security for food and other strategic resources.
Pvc Waterproof High Frequency Welding Machine,The machine have strong output power, reliable performance, using low-loss oscillation system, and special design oscillation tuner, so machine output power very strong and material can be welded in short time, automatic worktable help to improve production.
Using high sensitivity America-Imported anti-spark triode tube, which is useful for protect mould and products once machine over current. Adopting famous brand OMROM relay and CKC timer, greatly extend the life of the machine, reduce the machine failure.
