Design of wireless measurement and control system for LED street lights in smart park based on ZigBee
Based on the ZigBee wireless sensor network,combined with the construction requirements of the intelligent park,the LED street light intensity sensing control system is designed and realized,which mainly includes two parts:hardware design and software design.The hardware core part includes the design of LED sensing terminal node and Zigbee central module(coordi-nator).It is equipped with two-level high-performance MCU to provide edge computing capability at the edge of the network,it mainly involves the design of power circuit,serial port circuit,LED driver circuit,interface circuit,etc.Its software part first com-pletes the design and debugging of the coordinator control program and terminal node control program based on the IAR develop-ment environment and Z-Stack protocol stack.Finally,a monitoring software with an interactive GUI interface was developed and implemented based on VS software,achieving remote access and control functions.
