With reference to
The photodynamic energy converter 105 is used for converting light energy into electric energy;
The power supply managing module 103 is connected with the photodynamic energy converter 105, the processor 101 and the battery 104, and is used for providing the electric energy formed by converting the light energy to the processor 101 and the battery 104;
The triggering circuit 102 is connected with the photodynamic energy converter 105 and the processor 101, and is used for sending out a triggering signal to enable the photodynamic energy electronic label to be in a working state when an output of the photodynamic energy converter 105 reaches a set condition; and
The processor 101 is connected with the triggering circuit and is configured to receive the triggering signal and proceed to a working state according to triggering of the triggering signal so as to enable the photodynamic energy electronic label to be in the working state.
The photodynamic energy converter 105 can convert the light energy into the electric energy, and the photodynamic energy electronic label is in a sleeping state at ordinary times; the triggering circuit 102 triggers the photodynamic energy electronic label to work when the output of the photodynamic energy converter 105 reaches the set condition; not only the photodynamic energy electronic label can convert the light energy into the electric energy to charge the battery and supply power to modules such as the processor 101, but also the modules such as the processor 101 are in a sleeping state at ordinary times and consume little energy; when the photodynamic energy electronic label needs to work, illumination on the photodynamic energy electronic label is controlled to enable the output of the photodynamic energy converter 105 to reach the set condition, and then the photodynamic energy electronic label proceeds to the working state under the triggering action of the triggering circuit 102, thereby achieving an effect of prolonging the service life of the electronic label.
The set condition may be a sudden increase in the output of the photodynamic energy converter 105 caused by sudden reinforcement of illumination, or a sudden increase in the output of the photodynamic energy converter 105 caused by sudden weakening of illumination, or may be that the output of the photodynamic energy converter 105 reaches a set change rule due to a change in illumination in a set mode, e.g., illumination is suddenly reinforced to reach a certain value and then suddenly weakened, or illumination is suddenly reinforced twice or the like.
For example, the set condition is that in a first set time, an absolute value of a change value of an output signal of the photodynamic energy converter is greater than or equal to a set value; and when the output of the photodynamic energy converter 105 is increased by the set value or reduced by the set value in the first set time with respect to a previous moment, the photodynamic energy electronic label is triggered to work.
For example, the output signal may be a voltage signal or a current signal.
The photodynamic energy converter 105 may adopt a photodynamic energy converting sheet, or any other module capable of collecting light energy and converting the light energy into electric energy.
Further, when the photodynamic energy electronic label is triggered to work, the processor 101 may be triggered to work first, and then the processor 101 triggers other modules to work according to actual demands at the time.
At the moment, sending out the triggering signal to enable the photodynamic energy electronic label to be in the working state may be that:
The triggering signal is sent out to trigger the processor to work; and
After proceeding to the working state, the processor triggers the corresponding module to work or sleep according to current demands.
For example, after the processor 101 proceeds to the working state, if communication needs to be carried out, the processor 101 triggers a communication-related module to work, and if display needs to be carried out, the processor 101 triggers a display-related module to work.
The processor 101 in the embodiments of the present disclosure may adopt a Micro Control Unit (MCU), and the triggering circuit 102 may interrupt a triggering signal triggering the MCU to work by an IO (Input/Output) port.
In one embodiment of the present disclosure, a triggering condition may be sudden reinforcement or sudden weakening of light; at the moment, intensity of the output signal of the photodynamic energy converter 105 also may be suddenly increased or suddenly weakened accordingly; and at the moment, the triggering circuit 102 may be that:
When the output signal of the photodynamic energy converter 105 is changed to the set value in a set time, the triggering circuit 102 triggers the processor to work.
When sudden reinforcement or weakening of the light is taken as the triggering condition, the structure of the triggering circuit 102 may be shown in
An analog-to-digital converting module 201, configured to convert the voltage signal output by the photodynamic energy converter 105 into a digital signal;
A latch 202, configured to latch the digital signal output by the analog-to-digital converting module 201 for a set period T;
A digital-to-analog converting module 203, configured to convert the digital signal output by the latch 202 into an analog voltage signal;
A voltage dividing circuit 204, configured to carry out voltage division on the analog voltage signal output by the digital-to-analog converting module 203; and
A comparator 205, configured to compare a signal output by the voltage dividing circuit 204 to the voltage signal output by the photodynamic energy converter 105, wherein when an absolute value of a difference between a voltage signal currently output by the photodynamic energy converter 105 and a voltage signal output by the photodynamic energy converter 105 in a previous period is greater than or equal to the set value, a signal output by the comparator 205 triggers the processor 101 to work.
For example, the set value may be 50%, 60% or more of a value of the output signal in the previous period, and the embodiments of the present disclosure do not make any limit thereto.
The voltage signal output by the photodynamic energy converter 105 is latched for one period by the latch 202 so as to implement comparison between the current output of the photodynamic energy converter 105 and the output of the photodynamic energy converter 105 in the previous period; and if the light is suddenly reinforced or weakened, the difference between the current output of the photodynamic energy converter 105 and the output of the photodynamic energy converter 105 in the previous period is large so as to trigger the processor 101 to work.
A voltage output by the photodynamic energy converter 105 is converted into a digital signal by the analog-to-digital converting module, a digital amount of a voltage value is input into the latch, and an updating period of the latch is T; and an output voltage of the latch is converted into an analog voltage signal by the digital-to-analog converting module, and is output to the comparator through the voltage dividing circuit, wherein a voltage dividing ratio of the voltage dividing circuit is a, and the voltage dividing ratio may be regulated according to testing light intensity in the actual field. Assuming that V1 is a voltage output by the photodynamic energy converting sheet when a triggering lamp is not turned on, V2 is a voltage output by the photodynamic energy converting sheet when the triggering lamp is turned on, a may be determined according to a formula below:
In order to avoid that under a condition that the electronic label is triggered due to a false triggering case, the energy consumption is larger, and thus, after the electronic label is triggered to start to work, it may be specified that if a signal sent by a managing apparatus is not received in the set time, the electronic label proceeds to a sleeping state, and at the moment, the processor 101 is further used for:
After being triggered to start to work, if the signal sent by the managing apparatus is not received in a second set time, proceeding to a sleeping state again; and
After receiving the signal sent by the managing apparatus, if no triggering signal or not any signal sent by the managing apparatus is received in a third set time, proceeding to the sleeping state and enabling the photodynamic energy electronic label to proceed to the sleeping state.

Power supply managing circuit: the power supply managing circuit takes charge of keeping a voltage of the motherboard stable, coordinating an energy flowing direction and charging the battery.
Triggering circuit: the triggering circuit uses a voltage of the photodynamic energy converting sheet as a signal source, acquires a voltage change of the photodynamic energy converting sheet, converts the voltage change into an MCU wakening triggering signal and takes charge of wakening the MCU from the sleeping state.
In a state of no triggering signal, the motherboard is in the sleeping state; when the triggering signal is received, the triggering circuit converts an optical signal into an IO port interrupt triggering signal of the MCU, the MCU is triggered to be wakened, and the motherboard proceeds to a communicating state; after communication is completed, the motherboard proceeds to an updating state; and after update is completed, the motherboard proceeds to the sleeping state again.

For the false triggering problem caused by accidentally illumination reinforcement, after the photodynamic energy electronic label is triggered to be wakened, if the querying signal is not received in the second set time (e.g., in three minutes), it is illustrated that the label is abnormally wakened, and the label automatically proceeds to the sleeping mode; and for a case of not triggering due to factors of accidental shielding and the like, after a gateway wakens the label, if a label which is not wakened is queried in a set time, a control terminal is reminded to resend out a wakening signal, and if there is still the label which is not wakened, the manager is prompted to carry out manual processing.
