After the outbreak of the new crown epidemic, the offline demand scenarios such as traditional retail, catering, hotel and entertainment have almost completely stagnated, but some online demand has shown "explosive growth" and the online, digital and intelligent process of offline services has accelerated.

During the anti-epidemic period, new forms of "non-contact" transactions and services emerged. The Internet of Things and other cutting-edge technology applications have blossomed in many fields such as medical diagnosis, long-distance distribution and convenience services, becoming the key support for "scientific and technological warfare" and stable growth and livelihood protection.

"Non-contact" application was not only vigorously promoted during the anti-epidemic period, but in fact, in the industrial field, "non-contact" application has many advantages, which are embodied in:

1.Ensure the personal safety of equipment commissioning personnel;

2.Improve customer maintenance response level;

3.Greatly reduce the after-sale debugging cost of the equipment;

4.Through cloud data storage, the equipment data maintenance library is established at low cost;

5.Cross-platform data monitoring and alarm mode;

6.Data is directly acquired from the equipment side in real time to avoid man-made intermittent collection and errors and reduce the collection cost.
