Design of Gateway of 4G and ZigBee Network Fusion Technology Based on Intelligent Street Light System

摘要

In order to solve the problem of poor switching between wireless communication signals in traditional streetlight systems, the intelligent streetlight gateway based on ZigBee wireless sensor network and 4G network module is designed. The gateway uses Freescale's ARM Cortex-A9 embedded processor as the master chip, ARM Linux real-time operating system, using ZigBee and 4G fusion of communication technology to achieve the formation of wireless networks and the connection with the Internet, and gives the wisdom of street lamps Gateway hardware component structure and software implementation process. ZigBee module to complete the data acquisition, 4G module with the remote WEB server data transmission to meet the needs of lighting control and remote monitoring. The experimental results show that the gateway is reliable and stable, and is superior to wired gateway and GPRS gateway in packet loss rate and time response, and is suitable for application in intelligent streetlight system.
