Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

Used in the prior art are BLE electronic tags, which require a battery to supply power to operate, and which require battery replacement after the battery is exhausted to continue operating.

And the electronic tags in the embodiment of the application can be passive display tags, that is, the electronic tags can not carry a battery, and the electronic tags' screen can use a low-power electronic ink screen which displays the non-disappearance of the content after power failure, so that for the electronic tags, the electronic tags do not need to be powered by the battery, the condition that the battery is replaced due to the exhaustion of the battery does not need to be considered, and therefore, the trouble brought to the working personnel can be avoided.

Secondly, in the prior art, when data needs to be displayed on the BLE electronic tag, a base station needs to be used in addition to the mobile phone. And in this application, the optical signal sending end can directly transmit the data to be displayed to the optical signal receiving module of the electronic tag based on the optical signal, and does not need to use a base station.

In addition, in the prior art, after the mobile phone sends the data to be displayed to the cloud, the cloud sends the data to be displayed to the base station, and the base station sends the data to be displayed to the electronic tag. The distance between the cloud and the base station is usually very far, so that the cloud and the base station often need to communicate through the internet, the communication distance is very far, usually several kilometers or dozens of kilometers, even hundreds of kilometers and the like, and the distance between the base station and the electronic tag is often also far, usually several meters or even dozens of meters and the like.

In this application, the optical signal transmitting end does not need to use a network when transmitting the data to be displayed to the electronic tag, and can transmit the data to be displayed to the optical signal receiving module of the electronic tag by transmitting the light beam loaded with the optical signal, so that the optical signal transmitting end can be supported to transmit the data to be displayed to the optical signal receiving module of the electronic tag at a short distance, for example, a worker can hold the intelligent device to be close to the optical signal receiving module of the electronic tag at a short distance, for example, the distance is 10cm or 20cm and the like.

The farther the transmission distance is, the lower the difficulty of stealing the data to be displayed in the transmission process, that is, the higher the possibility of stealing the data, and the closer the transmission distance is, the higher the difficulty of stealing the data to be displayed in the transmission process, that is, the lower the possibility of stealing the data. Therefore, compared with the prior art, the method and the device can improve the difficulty of stealing the data to be displayed in the transmission process, further reduce the possibility of stealing the data to be displayed in the transmission process and improve the safety of the data.

Fig. 1a and 1b are block diagrams illustrating a data processing system according to an exemplary embodiment, as shown in fig. 1, the system includes a smart device 01, an electronic tag 02, and a cloud 03.

The intelligent device 01 can interact with the cloud 03 through the network module based on the network, and the intelligent device 01 and the electronic tag 02 can interact based on the light beam. The cloud 03 may be a server side.

The intelligent device 01 comprises a mobile terminal such as a mobile phone, an intelligent code scanning device and a tablet personal computer, and comprises a camera, a flash lamp and a data networking function (WiFi or other modes), wherein the flash lamp can be used as a light sending module, and can be used as a light energy collecting module of the electronic tag 02 by outputting more light energy when data is transmitted. Terminals such as a common mobile phone/tablet personal computer can be used as the intelligent device 01 capable of displaying the label update by installing the APP. The electronic tag 02 is provided with a screen (display module) including an electronic ink screen and the like, and the electronic tag 02 can display data on the screen. The light energy collection module of the electronic tag 02 converts the light energy into electric energy, and supplies the electric energy to the whole electronic tag 02 for use.

In this application, the optical sending module of the smart device 01 may transmit data to be displayed, which needs to be displayed on the screen of the electronic tag 02, to the electronic tag 02 based on the optical beam, and the optical signal receiving module of the electronic tag 02 receives the data to be displayed based on the optical beam and displays the data to be displayed on the screen (display module) of the electronic tag 02.

Specifically, the electronic tag 02 is provided with a tag identification ID, and the tag ID may be a unique ID number such as a barcode or a two-dimensional code printed when the electronic tag 02 leaves a factory, and a secret key corresponding to the tag ID may be preset and stored in the cloud 03. The intelligent device 01 scans a tag ID corresponding to the electronic tag 02 through a camera, and transmits the tag ID and data to be displayed to a cloud 03; optionally, the data to be displayed may also come directly from the cloud 03. The cloud 03 encrypts the data to be displayed according to the pre-stored key corresponding to the tag ID and then transmits the encrypted data to the intelligent device 01. The intelligent device 01 modulates the received data to be displayed by the light transmitting module and then transmits the modulated data to the electronic tag 02. An optical signal receiving module of the electronic tag 02 extracts an optical signal from the input light beam, and converts the optical signal into a command or data to be executed; the security verification module of the electronic tag 02 decrypts the command or data output by the optical signal receiving module by using the key corresponding to the tag ID, and transmits the data to the display module for display. The camera of the intelligent device 01 scans the display content of the electronic tag 02, compares the display content with the image data sent by the cloud 03, verifies whether the update is successful, and feeds back the result to the cloud 03.

The electronic tag 02 can adopt an electronic ink screen with low power consumption, and the display content can still be kept after power failure.

In the present application, the electronic tag 02 may have various design forms, and may include a card-shaped tag, a rectangular parallelepiped tag, an information display film that can be attached to another object or can be pasted to another object, and the like.

FIG. 2 is a flow chart illustrating a method of data processing, as shown in FIG. 1, for use in the system shown in FIG. 1, the method including the following steps, according to an exemplary embodiment.

In step S101, the intelligent device obtains data to be displayed in the form of an electrical signal, where the data to be displayed is used for displaying on a screen of an electronic tag, and an optical signal receiving module is arranged on the electronic tag;

in this application, when data displayed on the screen of the electronic tag needs to be replaced by data to be displayed, a user may input the data to be displayed on the smart device, and the smart device obtains the data to be displayed in the form of an electrical signal input by the user, and then executes step S102.

In step S102, the smart device modulates data to be displayed in the form of an electrical signal into an optical signal;

the present application may use any debugging method in the prior art to modulate the data to be displayed in the form of an electrical signal into an optical signal, and the present application does not limit the specific modulation method, and any modulation method is within the scope of the present application.

In one embodiment, the smart device may select one modulation scheme from a plurality of modulation schemes, and then modulate the data to be displayed in the form of an electrical signal into an optical signal using the selected modulation scheme.

For example, modulation may be based on alternating flashes of light, flash frequency, and light intensity.

For example, the electronic tag is used to display a certain article selling price, the latest selling price of the article is 32 yuan, and the selling price currently displayed on the screen of the electronic tag needs to be updated to 32 yuan, that is, the data to be displayed is "32 yuan".

The smart device may encode "3", "2", and "meta" separately, e.g., "3" as "1010", "2" as "1400", and "meta" as "5143".

Where "0" can be represented by an extinguished beam, the period of extinction can represent the number of consecutive "0", e.g., 1 "0" is 1ms,2 "0" is 2ms, etc., i.e., several "0" are several ms, and in this application, ms is milliseconds. A value above "1" can be represented by a lighting beam, and the greater the value, the greater the beam brightness. For example, the luminance corresponding to the value "1" is the first-level luminance, the luminance corresponding to the value "2" is the second-level luminance, the luminance corresponding to the value "3" is the third-level luminance, and so on, and the luminance corresponding to the value "9" is the nine-level luminance. The luminance of the number of stages with a large numerical value is larger than the luminance of the number of stages with a small numerical value.

Thus, the "32-element" code is "101014005143" and "101014005143" is the optical signal.

In step S103, the smart device transmits a first light beam loaded with an optical signal to the electronic tag;

so that the electronic tag receives the optical signal through the optical signal receiving module and displays the data to be displayed on the screen of the electronic tag.

Following the example in step S102, the optical signal is "101014005143", and the first light beam transmitted by the smart device to the electronic tag may include: first-level brightness light beam 1ms extinguishes 1ms, first-level brightness light beam 1ms, fourth-level brightness light beam 1ms extinguishes 2ms, fifth-level brightness light beam 1ms, first-level brightness light beam 1ms, fourth-level brightness light beam 1ms and third-level brightness light beam 1ms.

In step S104, the electronic tag receives a first light beam loaded with an optical signal and transmitted by the smart device;

following the example in step S103, the first light beam received by the electronic tag includes: first-level brightness light beam 1ms extinguishes 1ms, first-level brightness light beam 1ms, fourth-level brightness light beam 1ms extinguishes 2ms, fifth-level brightness light beam 1ms, first-level brightness light beam 1ms, fourth-level brightness light beam 1ms and third-level brightness light beam 1ms.

In step S105, the electronic tag acquires an optical signal from the first light beam;

next to the example in step S104, according to the first-level luminance light beam 1ms, the fourth-level luminance light beam 1ms, the second-level luminance light beam 2ms, the fifth-level luminance light beam 1ms, the first-level luminance light beam 1ms, the fourth-level luminance light beam 1ms, and the third-level luminance light beam 1ms, the optical signal "101014005143" may be obtained.

In step S106, the electronic tag demodulates the optical signal into data to be displayed in the form of an electrical signal;

in this step, the optical signal may be demodulated into the data to be displayed in the form of an electrical signal using a demodulation method corresponding to the modulation method used in step 102.

In the present application, after one data is modulated into an optical signal by using one modulation method, a special field may be added to the optical signal, and an identifier of the modulation method is stored in the special field, where the identifiers of different modulation methods are different, so that the electronic tag may obtain the identifier of the modulation method in the special field in the received optical signal, determine the modulation method according to the obtained identifier, then determine a demodulation method corresponding to the modulation method, and demodulate the optical signal into to-be-displayed data in the form of an electrical signal by using the demodulation method corresponding to the modulation method.

Next to the example in step S105, the optical signal "101014005143" is split into codes "1010", "1400", and "5143", then 1010"," 1400", and" 5143 "are decoded respectively to obtain" 3"," 2", and" element ", and then the codes are combined into" 32 element "in sequence, that is, the data to be displayed.

In step S107, the electronic tag displays data to be displayed on the screen.

Following the example in step S106, the electronic tag displays "32 yuan" on the screen, thereby achieving updating of the price of the product.

Taking an anti-counterfeiting asset tag of a passive dynamic two-dimensional code as an example, the soft solar energy is utilized to provide permanent electric energy for the electronic tag, and the encryption chip of the safety verification module dynamically generates the two-dimensional code according to time and displays the two-dimensional code on an ink screen. During the use, scan the dynamic two-dimensional code that the two-dimensional code and server side (high in the clouds) adopted the same encryption algorithm to generate through cell-phone APP and compare, verify the authenticity.

Taking the electronic tag as an example of an electronic price tag, the electronic price tag can be used in shopping malls such as supermarkets and retail stores, and is used for displaying relevant information such as price, name, discount, attribute and the like of a commodity,

when an electronic price tag is required to display certain data, the intelligent device can acquire the data in the form of an electrical signal and modulate the data in the form of the electrical signal into an optical signal. And transmits the first light beam loaded with the optical signal to the electronic price tag. The light beam can be a light beam provided by flexible solar energy, or a light beam emitted by a fluorescent lamp, and the like.

Then the electronic price tag receives a first light beam loaded with an optical signal and transmitted by the intelligent device through the optical signal receiving module; acquiring an optical signal from the first light beam; the optical signal is demodulated into the data in the form of an electrical signal and the data is displayed on the screen on the electronic tag.

The intelligent terminal may be a mobile phone + application program mode, for example, an application program is installed in the mobile phone, and the mobile phone executes the above-mentioned "acquiring the data in the form of an electrical signal" based on the application program, and modulates the data in the form of the electrical signal into an optical signal. And transmitting the first light beam loaded with the optical signal "to the electronic price tag.

Of course, the intelligent terminal can also be an intelligent code scanning gun and other devices.

In one example, the data to be displayed on the electronic price tag can be set on the intelligent terminal in advance, and then the intelligent terminal transmits the data to the cloud for encryption to obtain encrypted data returned by the cloud. When the electronic price tag is needed to display certain data, a user can input a write operation on the intelligent terminal, for example, a touch button for "writing data" is clicked, so that the intelligent terminal is controlled to execute "acquiring the data in the form of an electric signal", and the data in the form of the electric signal is modulated into an optical signal. And transmitting the first light beam loaded with the optical signal to the electronic price tag.

In another embodiment, the electronic tag may be an identity information card or the like for displaying identity information such as name and position and the like which are suitably encoded, or an electronic business card, a worker card, an electronic workstation card, a student card or the like.

In another embodiment, the electronic tag may also be an anti-counterfeit tag, an asset tag, and the like.

In the foregoing embodiment, it is necessary to display a new piece of data, for example, data to be displayed, in the electronic tag, so that the first light beam transmitted by the smart device to the electronic tag includes an optical signal modulated by the data to be displayed, that is, the light beam needs to be encoded.

In another embodiment, if the electronic tag is displaying old data before the smart device transmits the first light beam to the electronic tag, the electronic tag may erase the displayed old data before displaying the data after acquiring the optical signal from the first light beam and demodulating the optical signal into the data to be displayed in the form of an electrical signal.

In another embodiment, if the data to be displayed that is to be displayed in the electronic tag is required to be displayed on the electronic tag before and the data to be displayed is stored in the electronic tag, the first light beam transmitted by the smart device to the electronic tag may not include a light signal modulated by the data to be displayed, that is, the light beam does not need to be encoded, that is, the smart device may transmit only the light beam to the electronic tag, and the electronic tag may display the data to be displayed according to the energy provided by the light beam.
