Id number setting method, computer-readable storage medium and modular device

A non-transitory computer-readable storage medium storing one or more programs to be executed in a modular device that comprises a master building element and a plurality of slave building elements that are connected to the master building element, the one or more programs, when being executed by one or more processors of the modular device, causing the modular device to perform processing comprising:

• disconnecting the slave building elements from the master building element;
• setting ID numbers of all of the slave building elements to be a preset ID number;
• and
• assigning new ID numbers to slave building elements of N tiers that are connected to one output interface of the master building element in an order from first tier to Nth tier, wherein the slave building elements of the first tier are slave building elements that are directly connected to the output interface, the slave building elements of the Nth tier are slave building elements that are indirectly connected to the output interface through slave building elements of a (N−1)th tier, N is a natural number greater than 1.

A modular device comprising:

• a master building element;
• a plurality of slave building elements;
• one or more processors;
• a memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs comprises:
• instructions for disconnecting the slave building elements from the master building element;
• instructions for setting ID numbers of all of the slave building elements to be a preset ID number;
• and
• instructions for assigning new ID numbers to slave building elements of N tiers that are connected to one output interface of the master building element in an order from first tier to Nth tier, wherein the slave building elements of the first tier are slave building elements that are directly connected to the output interface, the slave building elements of the Nth tier are slave building elements that are indirectly connected to the output interface through slave building elements of a (N−1)th tier, N is a natural number greater than 1.
