In addition, the active electronic tag is powered by a battery, and is usually not powered off after being electrified and activated, and enters a low-power consumption mode in a non-working state so as to achieve the purpose of prolonging the service life of the battery.

Therefore, the current power supply activation mode of the active electronic tag improves the convenience, safety and reliability of the activation of the active electronic tag to a certain extent, but the activation accuracy of the active electronic tag cannot be ensured, and the power-off control of the active electronic tag cannot be realized.

Obviously, the circuit structure and the connection structure of each unit of the active electronic tag ensure that the active electronic tag can realize safe and reliable control of power supply activation and power failure of the active electronic tag according to the power supply activation control information initiated by the target object for the active electronic tag.

Therefore, in the embodiment of the application, when the active electronic tag detects the power supply activation control information initiated by the target object for the active electronic tag, the active electronic tag is switched from the tag power-off state to the power supply activation state, and if the power supply activation control information characterizes that the active electronic tag does not need to be activated by power supply, the active electronic tag is switched from the power supply activation state to the tag power-off state.

The power supply activating method of the active electronic tag according to the exemplary embodiment of the present application is described below with reference to the above-described system architecture and with reference to the accompanying drawings, and it should be noted that the above-described system architecture is only shown for the convenience of understanding the spirit and principles of the present application, and embodiments of the present application are not limited in this respect.

Referring to fig. 5, which is a schematic implementation flow chart of a power supply activating method of an active electronic tag according to an embodiment of the present application, an execution body uses an MCU as an example, and a specific implementation flow of the method is as follows:

s501: when the power supply activation control information initiated by the target object aiming at the active electronic tag is detected, the active electronic tag is switched from the tag power-off state to the power supply activation state.

Wherein, the power supply activation control information characterizes: whether the active electronic tag is activated by power supply.

Optionally, the power supply activation control information is used to indicate any one of the following cases:

1. activating the power supply of the active electronic tag, namely a tag power supply activation instruction;

2. the active electronic tag is powered off, namely a tag power-off instruction or a non-activation instruction;

3. and activating the power supply of the active electronic tag according to the power supply activation time length set by the target object for the active electronic tag, namely the tag activation time length.

In addition, the above power supply activation control information may also be used to indicate other situations or information related to power supply activation of the active electronic tag, and in this embodiment of the present application, the present application is not limited specifically, that is, the above description of the power supply activation control information used to indicate the situations is only a partial example, and is not an exhaustive result.

For example, when step S501 is executed, based on the radio frequency identification technology, the working state of the active electronic tag may be set by the dedicated contactless card reader-writer in a wireless manner, that is, the power supply activation control information is set, and when the MCU detects that the target object passes through the dedicated contactless card reader-writer and initiates/sets the power supply activation control information for the active electronic tag, the active electronic tag may be switched from the tag power-off state to the power supply activation state.

Therefore, the set power supply activation control information can be subjected to data writing by the special non-contact card reader-writer, and data reading by the MCU and the special non-contact card reader-writer; alternatively, when the MCU detects the power supply activation control information, the power supply activation control information may be stored in a dual interface unit (card) of the active electronic tag.

In an optional implementation manner, when the MCU detects power supply activation control information initiated by the target object aiming at the active electronic tag, a power switch of the active electronic tag can be communicated through a carrier detection unit of the active electronic tag, so that the active electronic tag is switched from a tag power-off state to a power supply activation state.

In this way, the carrier detection unit on the active electronic tag controls the power switch to be turned on while the special non-contact reader-writer is used for setting information (namely, power supply activation control information), so that the active electronic tag is electrified, namely, the power switch unit can be electrified by the carrier detection unit.

Further, after the active electronic tag is in the power supply activated state (i.e. the active electronic tag is powered on), the setting information (i.e. the power supply activation control information) in the dual-interface unit (card) can be read first, and the setting information (i.e. the power supply activation control information) is analyzed.

S502: and if the power supply activation control information characterizes that the active electronic tag does not need to be activated by power supply, switching the active electronic tag from a power supply activation state to a tag power-off state.

Therefore, when executing step S502, after analyzing the power supply activation control information, if it is determined that the power supply activation control information characterizes that the active electronic tag does not need to be activated by power supply, the MCU may switch the active electronic tag from the power supply activation state to the tag power-off state; the power supply activation control information is used for indicating that the active electronic tag is powered off, namely the power supply activation control information is a tag power-off instruction or a non-activation instruction.

In an alternative implementation manner, the MCU may generate a power switch off signal of the active electronic tag based on power supply activation control information characterizing that power supply is not required to activate the active electronic tag, so that the power switch of the active electronic tag is turned off based on the power switch off signal, so that the active electronic tag is switched from a power supply activation state to a tag power-off state; thus, the power-off processing of the active electronic tag based on the power supply activation control information for activating the active electronic tag without power supply is realized, namely, the active electronic tag enters an inactive state.

Otherwise, if the power supply activation control information characterizes that the active electronic tag needs to be activated by power supply, the active electronic tag can be maintained in a power supply activation state.

In an alternative implementation manner, the MCU may generate a power switch on signal of the active electronic tag based on power supply activation control information characterizing that power supply is required to activate the active electronic tag, so that the power switch of the active electronic tag is connected based on the power switch on signal, so that the active electronic tag is maintained in a power supply activation state; thus, the power-on/power-supply activation processing of the active electronic tag based on the power supply activation control information of the active electronic tag which needs to be powered on is realized, namely, the activation state is maintained.

Obviously, based on the power switch on/off signal generated by the MCU for the active electronic tag, the control of the MCU on the power supply activation/power-off processing of the active electronic tag is realized, and when the power switch does not output a signal at the carrier detection unit, the MCU can control the power supply activation/power-off processing of the active electronic tag.

In an optional implementation manner, when the MCU determines that the active electronic tag is in a power supply activation state, carrier detection interruption enabling is performed on a carrier detection unit of the active electronic tag, an interruption enabling result is obtained, if the interruption enabling result characterizes triggering carrier detection interruption, reading time is delayed according to set information, and next power supply activation control information is read and analyzed; thus, once the MCU determines that the active electronic tag is in a power supply activation state, the carrier detection interrupt enabling can be started, and when carrier detection interrupt triggering is generated (namely, new setting information (namely, power supply activation control information) can be written into by a special non-contact card reader-writer at the moment), the setting information (the power supply activation control information) is read and analyzed after 100ms of delay; the information delay read time set above is exemplified by: the delay is 100ms.

It should be noted that, if the interrupt enable result indicates that the carrier detection is not triggered, when it is determined that the active electronic tag is in the power supply active state, a loop determination is made as to whether the interrupt enable result indicates that the carrier detection is triggered, until it is determined that the interrupt enable result indicates that the carrier detection is triggered.

It can be seen that, based on the method steps described in steps S501 to S502, the active electronic tag can be controlled to be electrically activated by a wireless manner and an electromagnetic field; in addition, as the power supply activation of the active electronic tag is carried out through a specific communication protocol, the problem of false activation is solved, and the problem of false activation caused by the fact that the active electronic tag is activated in a point in a strong magnetic environment is solved; in addition, the power-off control and the effective working time maximization of the active electronic tag are realized; moreover, because the power supply activation and power-off processing (shutdown) operation of the active electronic tag is set by adopting special equipment (such as a special non-contact card reader-writer), the control mode is safe and reliable.

For example, referring to fig. 6, the following steps of the power supply activating method of the active electronic tag may be implemented, and the specific implementation flow of the method is as follows:

s601: an inactive state.

S602: setting information is written in, and meanwhile, the carrier detection unit controls the power switch to be turned on, and the active electronic tag is powered on.

Illustratively, the above setting information is power supply activation control information, including, but not limited to, any of the following:

And the active electronic tag is powered on, namely the active electronic tag is powered and activated.

After the steps S601 to S602, when the MCU determines that the setting information (power supply activation control information) initiated by the target object for the active electronic tag is detected and the active electronic tag is switched from the tag power-off state to the power supply activation state, the MCU may perform the following operations:

s603: the setting information is read.

S604: and analyzing the setting information.

S605: the setting message is "activate active electronic tag power supply", if yes, the step S606 is shifted to, if no, the step S610 is shifted to.

S606: and outputting a power switch on signal to enable the active electronic tag to be maintained in a power supply activated state.

S607: and (5) a power supply activation state.

It should be noted that, when step S607 is executed, the active electronic tag is powered on, i.e., is already activated by power supply, at step S602, so that it is in the form of maintaining the power supply activated state.

S608: if yes, go to step S609, if no, go to step S607, and again make a determination as to whether to trigger the carrier detection interruption.

S609: and (5) time delay.

After the delay, the process proceeds to step S603; illustratively, the delay is 100ms.

S610: and outputting a power switch closing signal to power off the active electronic tag.

After step S610, the process proceeds to step S601.

In summary, in the power supply activation method of the active electronic tag provided in the embodiment of the present application, when power supply activation control information initiated by a target object for the active electronic tag is detected, the active electronic tag is switched from a tag power-off state to a power supply activation state, so that power supply activation of the active electronic tag is achieved through electromagnetic field control; if the power supply activation control information indicates that the active electronic tag does not need to be activated by power supply, the active electronic tag is switched from a power supply activation state to a tag power-off state, so that power-off control of the active electronic tag is realized; therefore, by adopting the mode, the problem of false activation when the magnetic field controls the active electronic tag to supply power for activation in the related technology is avoided, namely, the activation accuracy of the active electronic tag is lower, and the problem that the active electronic tag cannot be subjected to power-off control is solved, so that the activation accuracy of the active electronic tag is improved, the power-off control of the active electronic tag is realized, and the safe and reliable control of the power supply activation and the power-off of the active electronic tag is realized.
