| It is significant to get image information from the field of environment monitoring, transport monitoring, intelligent living, medical service and visualization monitoring at battle, which offers an important opportunity to promote and improve the Wireless Sensor Network (WSN) technology. Wired image colleting and transmitting system is complex to design, while WLAN counterpart needs more power and covers limited area, which restraints the broad application of image monitoring at different ranges. The Wireless Multimedia Sensor Network (WMSN), which can collect and transmit the image information, can offer a good choice to resolve the former described problem.This paper analyzes the demands of collecting image and transmitting wirelessly among some area, calculating speed and transmitting speed of WSN, and develops a new system, which can overcome the shortage of existing monitoring system and transmit colleted image at some area.Firstly, was designs S3C6410 key board and S3C6410 bottom board circuit based on the S3C6410 processor. The main task is to accomplish the design of image collecting module and other related modules, which can collect image at some area.Secondly, the paper studies the characters of WSN, calculating speed and transmitting speed of CC2430. What's more, the paper designs the WSN node and the system can collect images and transmit efficiently through WSN based on ZigBee.Lastly, combined with the strong ability of image processing in S3C6410 and the characteristics of low power, low cost, distributed, and automatic networking in CC2430,the paper designs an image collecting and transmitting system based on S3C6410 and CC2430, which can collect and transmit the image information efficiently through WSN based on ZigBee.After test, the system is stable and easy to achieve, which can meet the demand of image collecting and ZigBee transmitting among some area. What's more, it overcomes the shortages of existing systems and realizes the expected target. |
