When the building blocks are the (i + 1) th layer building blocks, determining that the upper building block is the (i) th layer building block; and the control unit in the building block of the ith layer sends a data request to the building block of the (i + 1) th layer through the downlink contact.

The data request is used for requesting building block information of the building block and the lower building block from the building block by the upper building block, namely the data request is used for requesting building block information of the building block at the (i + 1) th layer and the building block information of the building block at the (i + 1) th layer from the building block at the (i + 1) th layer.

In step 402, the building block receives a data request and sends building block information for itself and lower building blocks to an upper building block.

The control unit in the (i + 1) th layer of building block receives the data request through the uplink contact; and then, the control unit in the (i + 1) th layer of building block sends the building block information of the building block and the building block information of the next-level building block to the control unit in the (i) th layer of building block through the uplink contact.

When the building block at the i-th layer is the building block at the previous level of the building block, the steps 401 to 402 are executed in a loop, so that the building block information of the building block is continuously transmitted to the building block at the previous level.

And the control unit of the (i + 1) th layer of building block receives the data request sent by the (i) th layer of building block through the uplink contact.

Step 4022, the building blocks determine the level of the building blocks as the level 1, and the levels of the lower building blocks are added by one to determine the level information of the lower building blocks.

The control unit of the (i + 1) th layer building block determines the level of the control unit as the 1 st level, and adds one to the levels in the level information of the i layer building block sent by the (i + 2) th layer building block to determine the level information of the i layer building block.
