Suzhou Zhiguan Yisheng Information Technology Co., Ltd. has been committed to the Internet of Things since its inceptionRFIDResearch and implementation of industry application technology. For years of service1000+Home to all types of customers.
RFIDtag, alias electronic tag. There are many kinds of electronic tags, eachRFIDLabels all have different characteristics.
Electronic tags can be divided into active electronic tags, passive electronic tags and semi-passive electronic tags.
Advantages: The efficacy distance is far, activeRFIDTag andRFIDreaderThe distance between can reach tens of meters.
Defects: large size, relatively high cost. The use time depends on the battery life.Applications: industrial production, freight logistics, instant road traffic, car access control, etc.
When passive electronic tag is nearRFIDreaderWhen the external antenna of the passive electronic tag converts the received radio wave energy into electromagnetic energy, excitationRFIDTag inside the chip and putRFIDThe information in the processing chip is pushed out.
Advantages: small size, light weight, low cost, long service life, can be made into a variety of shapes for different types of natural environments.
Defect: requires large output powerRFIDThe reader.Application: Warehouse management, fixed assets management,Logistics supply chain management,Library management, archival keeping, etc.
Semi-active electronic tag is equipped with the advantages of active electronic tag and passive electronic tag, as a special marker. Under normal conditions, it is in hibernation mode and does not start and does not spread to the publicRFIDThe data signal will only work after the tag is excited if it is within the range of the excited data signal.
Advantage: Compared with passive electronic tags. Semi-active electronic tags have a faster reaction rate and greater efficiency. Compared with active electronic tags, semi-active electronic tags consume less battery power.Defects: large size, relatively high cost.
Application: access control management, parking management, etc.
