摘　　要：介绍了一种基于ARM7处理器和CDMA1X无线数据业务的无线图像监控系统。监控终端以μCLinux操作系统为软件平台,以ARM7微处理器LPC2214为硬件平台,采用CMOS图像采集模块C328对图像进行采集和压缩,生成JPEG格式的数据。LPC2214将JPEG图像数据进行处理后发送到CDMA无线模块,通过CDMA1X业务将图像数据发送到监控中心。监控中心通过发送控制信号对监控终端进行实时控制。该系统主要应用在无人值守的变电站监控中。An embedded wireless image surveillance system based on ARM7 and wireless data service CDMA 1X was introduced. The monitoring terminal took the μCLinux system as the software platform, took the ARM7 microprocessor LPC2214 as the hardware platform, dedicated to the acquisition and compression of digital video by using the CMOS image acquisition module C328, and generated JPEG picture data. After the JPEG picture data was processed by LPC2214, the data was sent to the CDMA wireless module. Finally,the data was sent to the remote monitoring center through CDMA 1X wireless service. The remote monitoring center controlled the monitoring terminal by sending control signal. The system was mainly used for monitoring in the unattended substation.
