step S0.2: the acquisition terminal generates a module identification number according to a set rule and then sends the module identification number to acquisition equipment;
step S0.3: after receiving the module identification number, the acquisition equipment is burned to a communication control unit of the module;
step S0.4: the acquisition equipment sequentially lights each lamp bead of the module, records brightness information and chromaticity information of each lamp bead and position information of the lamp bead in a lamp bead matrix of the module, and sends the information to the acquisition terminal;
step S0.5: and the acquisition terminal corresponds the module identification number with the brightness information and the chromaticity information of each lamp bead in the module and the position information of the lamp bead in the lamp bead matrix of the module, and then sends the module identification number to the cloud server for storage.
