A street lamp controller includes: a switch configured to turn on or turn off a street lamp; a control module adapted to control the turning on and turning off of the switch; at least one detection module adapted to detect at least one data information relevant to operation of the street lamp; a data acquisition module connected to the at least one detection module and adapted to acquire the at least one data information detected by the at least one detection module; and a wireless transmission module communicating with a server and adapted to transmit the at least one data information acquired by the data acquisition module to the server and receive a control instruction sent from the server. The control module is communicated with the backend server via the wireless transmission module and is adapted to control the street lamp based on the control instruction received by the wireless transmission module. Thus, working state of the street lamp may be adjusted in real time based on the detected data information and intelligent control of the street lamp is improved.
