Double-activating method of active electronic label

Abstract

The invention relates to a method for bi-activating an active electronic tag, in particular to a method for activating an active electronic tag in the state of semi-dormancy by means of timing activation, and a method for activating the active electronic tag in the state of complete dormancy by means of passive activation. Two activation modes achieve free conversion by using a reader-writer, and the mode of passive activation is always effective in the life cycle of the whole active electronic tag. In the process of passive activation, passive activation equipment generates continuous low frequency signals, and sends the self ID. The signals are received by passive receiving equipment to generate a pulse signal, which is to be transmitted into the tag to activate an internal circuit of the tag and make the state of the tag converted into working from complete dormancy. The method can ensure that the active electronic tag works coordinately under the control of two activation modes to be awoken within 1ms, ensure practicability and reliability of the reading and writing of data, and prolong the service life of the active electronic tag with low energy consumption.

Description

technical field [0001] The patent of the present invention relates to the technology of electronic tags, especially the activation method of active electronic tags in terms of service life and real-time reading. Background technique [0002] With the progress and development of society, active electronic tags have been widely used. The battery capacity of the power supply of the active electronic tag is limited, and effective low power consumption technology must be adopted to prolong its service life and reduce its use cost. The power consumption of the electronic tag depends not only on the power consumption of the chip itself, but also on the system-level low-power design method, especially the use of the activation method of the electronic tag to control the transition between its dormant and active states, which can greatly reduce the power consumption of the electronic tag. Tag dynamic power consumption, prolonging its life. [0003] The current active electronic tag...

AI Technical Summary

Problems solved by technology

[0004] (1) In the absence of a reader, the tag will also be activated regularly, wasting power consumption for listening;

[0005] (2) If the sleep time of the tag is too long, the tag may not be able to respond in time when there is a need to read and write data, and cannot meet the real-time requirements

If the set sleep time is too short, the tag will be activated repeatedly, wasting more listening power consumption

[0006] (3) There is always a timer working in the tag, which consumes battery energy

[0007] It can be seen that the timing activation method alone cannot achieve the best effect
