摘　　要：建立基于ZigBee的无线图像传输系统。设计简单图像传输协议,详细介绍其图像数据帧格式,通过增加1个字节的帧计数建立确认机制和重传机制,保证图像数据帧的可靠传输。以C++Builder作为开发工具,主机软件采用多线程技术,结合简单图像传输协议,实现图像数据的快速传输及图像显示,提高数据传输速度。测试不同波特率下不同发送延时对图像传输的影响,给出实验结果并对影响图像传输速度的因素进行讨论。A wireless image transmission system based on ZigBee has been set up. The simple image transmission protocol is designed with detailed introduction of its format of image data frame. By adding one byte frame counter, the acknowledgement and retransmission mechanism are established, which ensures the reliable delivery of data frame. C ＋ ＋ Builder is used as the development tool, the host software achieves fast image data transmission and image display as well as improves data transmission rate through multi-thread technology and in combination with simple image transmission protocol. The impacts of varying time delay to image transmission under different baud rates are tested. The test results are presented and the factors that affect the rate of image transmission are discussed as well.
