摘要
为了满足设施农业中数据采集、无线传输和远程应用的要求,设计并实现了一种以STM32W108及AX22001为核心芯片的ZigBee-WiFi无线网关,该无线网关实现ZigBee与WiFi网络间的数据互通,拓展了设施农业装备的感知、监控范围。无线网关根据ZigBee、WiFi信号的频谱特性,采用信道选择和复用的方式减少ZigBee与WiFi间的信号互扰。测试结果表明,所实现的无线网关信号稳定,丢包率小,运行可靠,可满足设施农业装备数据采集和远程应用的需要。
In order to meet the requirements ofdata acquisition,wireless transmission and remote application in facility agricultur,a ZigBee-WiFi wireless gateway based on STM32W108 and AX22001was designed to extend the perception and monitoring scope of agricultural facilities and equipment.Channel selection and software channel multiplexing approach are used to reducing interference between ZigBee and WiFi signals based on their spectrum characteristics in this wireless gateway.The experimental results show that this wireless gateway has stable signal,lower data packet loss rate and can interconnect ZigBee and WiFi networks to satisfy the needs of data acquisition and remote application in facilityagriculture.
