摘要
为了对野外无人值守的自动气象站可视化监控,基于C328摄像模块,以ARM7体系结构的LPC2387芯片为处理器,嵌入μC/OS-Ⅱ操作系统,采用多任务软件设计方法,通过复用自动气象站的GPRS模块与上位机的通信,提供上位机命令、定时、红外感应三种触发方式,设计了自动气象站可视化监控系统.将监控系统移植到自动气象站后,测试表明,系统在保障气象要素信息安全传输的前提下,能够及时获取气象要素传感器运行时候的图像信息,延迟时间不超过20s,满足自动气象站可视化监控的管理需求。
In order to realize visual monitoring for automatic weather station （AWS） in the field,based on the camera module C328, using LPC2387 with ARM structure as the processor and embedding u C/ OS-Ⅱ operating system, the visual monitoring system of automatic weather station is proposed,which adopts multitask software, communicates with the PC by utilizing GPRS and provides three trigger modes including command, timing and infrared inductive. After transplantation of monitoring system to automatic weather station, the experimental results show that the system can acquire the image information from meteorological element sensor under the condition that the element security is guaranteed. And the delay time is within 20 seconds, which is satisfied with management requirements of visual monitoring for AWS.
