Confucius said that the three-person line must have my teacher. Although in terms of land area, China ranks in the top five in the world, but in some 'small countries' and 'small areas, there are still places for learning and learning. Like Israel. This country, the land area is only comparable to the two capitals of China, and most of them belong to the desert, but it is such a place that should be barren and absurd in traditional cognition, but has a 'European fruit basket', 'the world's first milk production 'A variety of titles. The root cause, the use of various scientific and technological means to assist agriculture, animal husbandry and other high yields, this land has almost miraculous phenomenon.
In the last issue, the author found the common characteristics of Israel and our dairy companies: trying to increase the production of dairy cows with limited resources. In this way, we tried to expose what technologies can be used to assist the dairy cows to increase production. In this issue, we passed Some products on the International Agricultural Science and Technology Expo held in Israel this year, look at the innovative ways of using sensors by Israeli companies, and explore the ways of reference for related companies.
At the expo, an Israeli company used sensors for irrigation and fertilization of field crops. Using high-precision sensors developed in combination with control systems, it is possible to fully realize autonomous field crop irrigation and fertilization. Currently, China's smart water and fertilizer machine usually requires labor. Irrigation and fertilization procedures are set up to achieve irrigation and automation of fertilization projects. However, this method cannot accept feedback from the soil in the field. It is only suitable for greenhouse agriculture with a complete system. However, direct introduction of such fertigation systems requires different water quality. The resulting clogging phenomenon and the high cost of introduction, etc., also require relevant equipment manufacturers in China to speed up the research and development of equipment and promote the improvement of irrigation and fertilization systems.
Another Israeli company has developed a fruit and vegetable ripening detection system. This detection system can be installed as an application on a mobile phone. After taking photos of fruits and vegetables with a mobile phone, the sensor wirelessly connected to the mobile phone can automatically receive the picture information, and Feed the sugar content, net weight, color, size and other information about the maturity of the fruit to the screen of the mobile phone.
In fact, many fruit maturity detectors have already appeared in China. However, they do not use sensors for analysis. Some devices use different characteristics such as different maturity of fruits and vegetables and different external hardness. They also use photoelectric methods to measure fruits and vegetables. The chlorophyll content, to determine the maturity of fruits and vegetables; more advanced, more widely used fruit maturity detector is to use the near-infrared light detected by the hair to non-destructive testing of fruit and vegetable foods, the equipment can feedback the sugar and sugar of the fruit and vegetable within 3s, acidity , maturity, color and other indicators. But this device weighs 1.5kg, there are inevitable defects in the convenience of carrying. So comprehensively, the company developed a way to wirelessly connect sensors using mobile phones to fruits and vegetables. The detection of maturity is a relatively high-quality choice, and it is hoped that relevant enterprises in China can speed up the pace of research and development in this area.
We know that the sensor is actually a detection device, which can convert the perceived information into the information that people need, and is widely used in automation and intelligent equipment. Nowadays, China's food industry is in the midst of intelligent wave, innovation The use of sensors, the rational use of sensor equipment can greatly enhance the sensor's sensing ability, and promote the further development of China's food production equipment.
