Title:
NB-IOT TECHNOLOGY-BASED INTELLIGENT STREET LAMP MEASUREMENT AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/224528
Kind Code:
A1
Abstract:
The present invention provides an NB-IoT technology-based intelligent street lamp measurement and control device, comprising an MCU circuit, and an electrical parameter measurement circuit, an NB-IoT communication circuit, a dimming circuit, and a switching control circuit which are respectively connected to the MCU circuit. The electrical parameter measurement circuit determines electrical parameter data and electric energy data of a street lamp load and transmits same to the MCU circuit. The MCU circuit actively uploads the electrical 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 connection/disconnection of the street lamp load according to the switching signal. The dimming circuit adjusts the light intensity of the street lamp load according to the dimming signal. On the basis of the solution provided by the present 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 the purpose of fine power utilization. A variety of switching and dimming strategies are realized, the lighting power loss is effectively reduced, and the purpose of energy saving and emission reduction is achieved.
