Preferably, the first wireless module 101 is a Bluetooth module, and the second wireless module 201 is a Bluetooth module. In this embodiment, Bluetooth connection is used as an example.

[0024] In the specific operation process, the second wireless module 201 and the first wireless module 101 are successfully connected via Bluetooth; the wireless positioning terminal 200 sends a lamp flashing instruction to the smart street lamp 100 through the first wireless module 101, and after the street lamp control module 102 parses the lamp flashing instruction, the smart street lamp 100 flashes, and returns the flashing success response instruction to the wireless positioning terminal 200 through the first wireless module 101 and the second wireless module 201, and the wireless positioning terminal 200 identifies the smart street lamp 100 as the target street lamp. Among them, the number of flashes in the flashing instruction is N, and after the street lamp control module 103 parses the flashing instruction, the number of flashes of the smart street lamp 100 is controlled to be N, where N≥1, and the flashing number 3 is used as an example in this example. Specifically, the wireless positioning terminal 200 sends a lamp flashing instruction to the smart street lamp 100 through the second wireless module 201, and the number of lamp flashing times in the flashing instruction is 3; the street lamp control module 103 parses the instruction and controls the smart street lamp 100 to flash 3 times.
