[ China Instrument Network Instrument Development ] With the advancement of smart manufacturing, many organizations have organized many events to inspire people to carry out more inventions. Recently, the 2018 Microsoft Innovation Cup was held in the finals of Guangzhou, Guangdong Province. In the finals, the handheld smart spectrometer developed by the 98k squad won the championship.
It is reported that the Microsoft "Innovation Cup" that was founded in 2003 is the largest student science and technology competition in the world. More than 2 million students from 190 countries and regions have participated in the "Innovation Cup" and related activities. As early as 2004, Chinese players participated in the Microsoft Innovation Cup and scored many achievements in the world. As of now, they have won 5 first prizes, 9 second prizes, 11 third prizes and several special awards. .
Food safety has always been an area of ​​great concern for people. China is also building inspection booths throughout the country to help food testing. The 98k squad is facing the problem of food testing and has developed a new handheld spectrometer.
The spectrum is the same as each person's unique fingerprint, so the differences in the characteristic line (fingerprint) of the corresponding food can be analyzed and identified by its composition, nature, and status. The pork that has been put for a day and the pork that has been put for several days have different spectra. The spectrum of fresh oil and cooking oil is also different.
The 98k squad uses this principle to upgrade the database of things samples and expand the types of foods detected by the spectrometer. At the same time with accurate detection, the spectrometer also greatly improves the detection efficiency. Spectral detection is not only non-destructive, but also results directly. In terms of energy, the R&D team switched to the USB port of the mobile phone, which is more of a civilian preference. At present, the 98k squad has completed the test of the poisonous floss and pollen samples through a spectrometer, and is undergoing tests for pork deterioration and waste oil.
In addition to spectrometers, R&D teams have also invented safety helmets for those in need of security protection against frequent mine problems. In the event of a miner falling or falling, even if it is 600 meters downhole, the helmet can be automatically positioned and an alarm issued to inform emergency personnel.
Through the holding of these events, not only can people increase their interest in scientific research, expand their influence, but also invent more interesting and practical instruments.
