| Abstract: | 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. |
