| Along with the fast development and the widespread application of the computer technology,the network technology and the wireless communication technology,the wireless sensor network has become apopular and advanced research field recent years. Wireless sensor networks shows large potential in a wide range of applications,such as, military,cnvironmental monitoring,medical sanitation,smart spaces.It was the promising technique in the 21st century.Through to the research of wireless sensor network development present situation, the tendency and the water environment multi-parameter monitor characteristic,this article proposed a wireless sensor network monitor system solution,which faces to the water environment multi-parameter wireless monitor application,analyzed the system design goal and the function,pointed out the hardware platibrm design request and the principle of design.Depended on the science and technique project of Jiangsu province "intelligent multi-parameter high-precision detecting and control instrument based on bus" in 2006,designed the hardware platform based on the Silicon Labs C8051F310 processor and TI CC2420 radio frequency chip,described the hardware platform each function module in detail,realized and improved the protocol of SimpliciTI and IEEE 802.15.4/Zigbee on the platform,and finally carried on the test to the system.The overall system takes wireless sensor network technology as a core,which strengthens the system flexibility,the maintainability and the extendibility.Meanwhile the system modulation and the open style structure enable the system to have a good probability.Applying the wireless sensor network technology in the water environment multi-parameter monitor involves to the sensor technology,the wireless communication, the computer application technology and so on many kinds of technologies.So far, along with the science and technology unceasing progress,it also in unceasingly consummates,and the prospect especially is broad. |
