Radio-frequency (RF) identification (RFID) is a kind of wireless communication technology, can read and write related data by radio signals identification specific objective, and without the need to setting up machinery or optical contact between recognition system and specific objective.
Wireless signal is the electromagnetic field by furnishing radio frequency, and data are sent out from the label be attached to article, with automatic Identification and these article of tracking.The elect magnetic field that some label sends from recognizer when identifying just can obtain energy, does not need battery; Also there is label itself to have power supply, and initiatively can send radiowave (electromagnetic field of furnishing radio frequency).Label contains the information of Electronic saving, can identify within several meters.With bar code unlike, radio-frequency (RF) tag does not need to be within recognizer sight line, can embed within tracked object yet.
Many industries have all used REID.Label is attached to an automobile just aborning, this car progress on a production line just can be followed the trail of by manufacturer.The place of medicine can be followed the trail of in warehouse.Radio-frequency (RF) tag also can invest on livestock and pet, facilitates the positive identification (actively identify and be meant to prevent several livestocks from using same identity) to livestock and pet.The identification card of radio-frequency (RF) identification can make employee be entered the building part of pinning, and the radio frequency transponder on automobile also can be used for imposing the expense in charging section and parking lot.
Displacement transducer is also called linear transducer, and be a kind of linear unit belonging to metal induction, the effect of sensor is that various measurand is converted to electricity.In process of production, the measurement of displacement is generally divided into measurement full size and mechanical shift two kinds.Different by the form of measured variable conversion, displacement transducer can be divided into analog and digital two kinds.Analogly can be divided into again physical property type and structural type two kinds.
Gyro sensor be a kind of be simple and easy to move and the location of gesture and control system based on free space.Imaginary plane brandishes mouse, and the cursor on screen will and then movement, and can draw a circle and click keys around link.When giving a lecture or leave desk, these operations can both realize easily.Gyro sensor has been widely used on this kind of Mobile portable equipment of mobile phone, the three-axis gyroscope technology of such as IPHONE.
Current REID is all No. ID, the identity of launching people or thing, and this No. ID some fixing information being only associated with people or thing, the information such as dynamic position, direction, angle, displacement can not be provided.
