The invention provides an intelligent street lamp measurement and control device based on the NB-IoT technology. The device comprises an MCU circuit, and an electric parameter measurement circuit, anNB-IoT communication circuit, a dimming circuit and a switching control circuit which are respectively connected with the MCU circuit. The electric parameter measurement circuit determines and transmits the electric parameter data and electric energy data of a street lamp load to the MCU circuit. The MCU circuit actively uploads the electric parameter data and/or electric energy data to a remote control center according to a preset time interval, receives a control instruction from the remote control center, and sends out a switching signal and/or a dimming signal according to the control instruction. The switching control circuit controls the on-off of the street lamp load according to the switching signal. The dimming circuit adjusts the light intensity of the street lamp load accordingto the dimming signal. Based on the scheme provided by the invention, the running state of a street lamp can be monitored in real time and the energy consumption can be analyzed, so as to achieve thepurpose of fine power utilization. A variety of switching and dimming strategies are realized, the lighting power loss is reduced, and the purpose of energy saving and emission reduction is achieved.
