Background technology
Wireless sensor network WSN (Wireless Sensor Networks) technological incorporation communication technology, sensor
Technology and computer networking technology, are the popular research of multi-crossed disciplines.As one of 21 century most important technology, begin earliest
Eighties of last century seventies, used at first by U.S. army on Vietnam battlefield.From the eighties in last century, U.S. Department of Defense successively throws
Enter the research that substantial contribution is used to monitor " over the horizon " battlefield Sensor, main achievement has the distributed sensor system of U.S. army
System, naval's Cooperative Engagement Capability system and long-range battlefield sensor-based system.The mark that wireless sensor network technology formally rises is
In 1999 by global famous business-to business magazines (b to b)《Business Weekly》It is classified as one of 21 most potential and influence power technologies.Nothing
The multihop self-organizing network system that line sensor network is formed by a large amount of inexpensive sensor nodes disposed in monitored area, section
Cooperated between point, so as to realize the transmission of the perception of external environmental information, data acquisition and information.
Wireless radio frequency discrimination RFID (Radio Frequency Identification) technology utilizes radiofrequency signal space
Coupling is propagated, to realize non contact transmission and the identification of information, and it is that a kind of speed is exceedingly fast the automatic identification and letter of ultrahigh in efficiency
Cease acquisition technique.In World War II earliest use militarily, thereafter with the fast development of semiconductor technology,

Automatic management etc. is managed, the various aspects of our lives have been penetrated into, the life with us contacts more and more closer.
Currently, both technologies are that both fusions use seldom quilt along respective technology path explored going forward
Consider.But for the angle of Communication Development, the communication system that RFID and WSN are constituted each has its weak point, limited
Its application field scope is made.Wireless sensor network does not use overall identification typically to the node in network, and RFID is to node
It is identified but transmission range limitation is obvious, therefore, combining RFID has opportunity while as inevitable with WSN.
WSN sensing nodes realize there is data redundancy and mass flow discrepancy between networking, node based on distributed networking protocol
Weighing apparatus, while being required to adjust automatically to adapt to external change.Therefore network system complexity needs greater energy consumption to maintain network
Presence.The reason for data acquisition errors are larger is caused to come from many factors：High-frequency crosstalk from radio-frequency module, come from
The power supply crosstalk of sensor in itself etc..In addition to the power supply crosstalk of sensor in itself, other crosstalks are passed by power supply and ground
Enter ADC sampling channels.
