Active electronic tags as well as system and method applying active electronic tags

Abstract

The invention provides multifunctional active electronic tags as well as a system and method applying the active electronic tags in order to solve the problem of achieving low power consumption, bidirectional communication, working on demand and remote information transmission of the active electronic tags. The system comprises a control processor, a coordinator, the active electronic tags and a reader, wherein the active electronic tags are used for receiving command signals in the time period (namely the moment of monitoring the signals after waking from periodic sleep) of monitoring the states; the active electronic tags comprise soft filtering modules and hard filtering modules; the soft filtering modules are used for judging whether the address codes of the signals received by the active electronic tags in a first channel are correct; and the hard filtering modules are used for filtering the signals at the hardware side before the signals are subjected to soft filtering so as to get rid of the invalid signals. The invention has the beneficial effects of achieving low power consumption, bidirectional communication, working on demand and remote information transmission of the active electronic tags, further optimizing the standard communication flows of the active electronic tags and prolonging the service lives of the tags.

Description

technical field [0001] The invention relates to information transmission technology, in particular to an active electronic tag and its application system and method. Background technique [0002] The existing active electronic tags are mainly used for long-distance identification and management of targets such as people, objects and vehicles. Its basic working method is to read the ID number of the active electronic tag installed on the identified target through radio frequency communication, and then use the ID number to call the corresponding ID number stored in the database of the control processor (such as a computer) in advance. The relevant information of the ID number is used to realize the identification and management of the target. Therefore, the application of this technology must be connected with the relevant database in the control processor. [0003] At present, the most commonly used working method of active electronic tags is to periodically and actively t...

AI Technical Summary

Problems solved by technology

Active electronic tags need to have two-way and long-distance communication capabilities, and need to have the ability to handle a large number of tags, but at the same time consume very low power

However, there is currently no proposed solution that meets this need.
