摘要
针对精准农业监测系统中终端设备通过WiFi接入到无线传感网络的需求,设计ZigBee/WiFi农业网关。该网关通过ZigBee协调器传输终端节点采集的温湿度和光照信息;以LPC1768为主控制器,WiFi模块为信息转换器,实现ZigBee信息到WiFi信息的相互转换;将WiFi模块配置指令写入主控制器,省去使用网关前的配置操作。定义ZigBee数据包,设计ZigBee协调器串口和无线数据接收、主控制器双串口和配置WiFi模块程序等。测试结果表明,该网关能够满足各终端设备WiFi接入,且传输转换信息稳定。
According to the demand for the terminal equipment of precision agriculture monitoring system to access the wireless sensor network through the WiFi, ZigBee/WiFi agricultural gateway is designed. This gateway uses the ZigBee coordinated transmission terminal nodes to collect data of temperature, humidity and illumination information. With lpc1768 as its main controller and WiFi module as the information converter, the gateway can achieve the conversion between ZigBee information and WiFi information. WiFi module configuration directives are written into the main controller to eliminate the use of network before the configuration operation. The gateway also defines the ZigBee data packet, designs ZigBee coordinator serial port and wireless data reception and the main controller dual serial port, and also configures the WiFi module program, etc. Test results show that the gateway can meet the WiFi access of each terminal device, and the transmission and conversion information is stable.
