| 摘 要： | 研制了基于GPRS技术的远端无线图像采集系统,利用已有移动通信GSM无线网络实现图像数据的传输,具有覆盖面广,无需增加传输设备和线路的特点。采用JPEG硬件压缩编码技术,对静态图像进行压缩编码,较大地减少了网络传输的数据量,节省了网络资源,提高了图片的传输速度。系统硬件结构采用微控制器加可编程逻辑控制芯片(MCU+CPLD)的方案,各子功能由标准通用模块完成,降低了系统复杂度,提高了系统整体性能,用户可以用PC机在Internet上实现图像的远端采集与现场监控。该系统经过现场运行与测试,达到设计要求。

| Abstract: | Distal wireless image acquisition system based on GPRS technologies is able to transmit image data through existing mobile communication GSM wireless network.The system can be used in most occasions without special equipment.Images are compressed and encoded with JPEG standard by hardware to reduce the transmission quantity of image data.Micro controller and programmable logic device are used in system hardware.This structure can connect the high speed part of image compression control with the low speed part of data transmission.Modules with general standard interface are used in the image capture system.The performance is increased with the reduction of system complication.Users can capture the image of the actual scene,and can also inspect and control it remotely.By debugging and running in scene,it shows that the image capture system can meet the requirement of design. |
