| Wireless Multi-sensor Network System is composed of Command Center and lots of Detection Units. Each Detection Unit, placed in the given area, integrates kinds of sensors with wireless transmitter and receiver. Command Center can decode the compressed information, display it and monitor the area on the monitoring platform by means of bi-directional communication between it and each unit. In the System, the research of the image data communication by wireless channel is a very important project. This paper details in the development of image data communication by wireless channel, which is based on the research findings achieved during the tenth five-year Plan for National Economic and Social Development. It mainly includes the following items: design of the data communication by wireless channel, design of the image sampling system and the design of different units developed to system including the Modem and unit of radio interface. According to the system need, the research has constructed under the monolithic integrated circuit control modem module, the modem and the wireless military station's interface module in the wireless data transmission system aspect. In image gathering system aspect, using the FPGA and SAA7111 to carry on the simple treatment to the image, and has achieved the effective transmission image goal. The micro controller string mouth correspondence development use assembly language, the FPGA development uses the Verilog hardware to describe the language. |
