The house number of object grid is a digital production means of anchoring land. Based on the object lattice in Wei Xu's "code chain new world, object lattice new economic system", the inventor of the global two-dimensional code "Sweep" patent technology, according to the remote sensing data of Beidou satellite, the earth surface of the three-dimensional world is digitally divided into grids of 10m× 10m. Each object lattice (grid) has a unique "Beidou latitude and longitude".
The object lattice can correspond to the geographical coordinates in the real world one by one when networking through scanning code, and match different weights according to the level of behavior. Because the Internet of Things is marked by latitude and longitude, it replaces the IP address/domain name in the network and appears in the digital "Internet of Things Digital Earth". Clicking on different object codes can replace IP and access different services. The service provider is equivalent to the service provider of the website. In this way, a brand-new Internet of Things ecosystem has been established. "Wu Ge" is anchored by real physical time and space and precious land.
