Description
Technical field
The utility model relates to field of radio frequency identification, is specifically related to a kind of wireless sensing RFID information acquisition terminal that adopts the integrated RF identification sensor.
Background technology
Radio-frequency (RF) identification (RFID) technology is a kind of non-contact automatic identification technology (following common name RFID technology) that utilizes radio communication to realize.RFID utilizes the automatic recognition objective object of radiofrequency signal and obtains relevant information, and it is an important branch of automatic identification field.RFID have a plurality of labels of single treatment and treatment state can be write label, not be subjected to the restriction of size and shape, environment resistant strong, many advantages such as penetrability is strong, the memory capacity of data is big, can reuse.Therefore, the RFID technology has been widely used in various fields such as society, economy, national defence in recent years, in all conglomeraties such as manufacturing industry, service sector, demonstrate huge development potentiality and application space, and will be to the raising of entire society's level of IT application, and strengthen national defense safety etc. and produce wide influence, its prospect is very considerable.
Although it is a kind of based on label that RFID also can often be described as, and be used for the sensor of recognition objective, with respect to the sensor on the ordinary meaning, rfid interrogator still has a lot of shortcomings.Because what label can be stored only is a unique identification code, can not respond to the change of current environment in real time.And the read-write scope of rfid system also is subjected to the influence of distance between read write line and the label.Therefore improve the sensing capability of rfid system, the covering power that enlarges rfid system is a problem demanding prompt solution.
Wireless sensor network (WSN) be low by a large amount of power, volume is little, low price, have " intelligence " autonomous measurement and control network system that communication and the small sensor node of computing power constitute, the general intensive unattended guarded region that is laid in, can independently finish appointed task according to environment, its objective is the information in perception synergistically, collection, the processing network coverage and provide it to user (hereinafter to be referred as WSN).WSN has been subjected to global concern on a large scale at present, becomes popular research field.WSN has integrated sensor technology, embedded calculating, automatic control technology, wireless communication technique, and the environmental information around the detection that can be real-time, induction, collection.
Along with more and more higher demand is used in development and each field of RFID and WSN technology, RFID and WSN integrate and the integrated inevitable development trend that become.One, RFID label of new generation, especially initiatively the RFID label has embedded sensing function usually.In addition, in the application based on sensor network, usually need individual sensor or destination object are found and discerned.Sensing and recognition technology are integrated, add the configuration of global I T and communication system, can allow people that the state of physical world is had more deep understanding, and in order to instruct or to change the interactive mode of people and physical environment, realization is to the more efficiently mutual and management in many fields, as fields such as logistics management, tele-medicine, environmental monitoring, housing administration and control, security maintenance and commercial Application.
The application of RFID and WSN is different.Most WSN is applied in the planned system that physical environment is monitored, and RFID then is that the single product that are applied in the supply chain are discerned.Although it is different that RFID and WSN have aspect a lot, the both interrelates by infotech and physical world, possesses the condition that combines.
Using at present comparatively ripely at the RFID at wireless sense network end, but only all is at a certain field or the single design of a certain engineering, and there is no at the multiple sensors collection is the multifunctional application design of one.
