Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of electronic price tag, and particularly relates to a method for pushing an electronic price tag, a terminal and a storage medium. BACKGROUND

[0002] Electronic Shelf Label (ESL) is used to replace the traditional paper price tag and has become a trend, and has become a standard in the new retail industry. Some large supermarkets use electronic price tags. The use of electronic price tags improves the work efficiency of the store, releases the hands of the employees, and can save a large amount of manpower and time cost for the merchant in the long term. The electronic price tag needs to update the product information displayed on the electronic screen from time to time, and this process is generally completed by pushing the latest product information from the server to the corresponding electronic price tag (that is, in the process of pushing the latest product information to the corresponding electronic price tag from the server, the corresponding electronic price tag is directly pushed without any processing on the product image size carrying the latest product information). However, due to the various sizes of electronic price tags, and the different sizes of product images carrying product information, the existing way of directly pushing new product information to electronic price tags to complete the corresponding update operation is prone to compatibility problems, that is, when the size-mismatched product information is pushed to the corresponding electronic price tag, either the pushing fails or the price tag displays abnormally after the pushing succeeds, thereby seriously affecting the user experience.

[0011] Optionally, after the step of obtaining a new information picture of the pre-updated commodity and comparing size information of the new information picture with pre-stored size information of the pre-push electronic price tag to obtain a corresponding comparison result, before the step of pushing the display picture to the pre-push electronic price tag for display on an electronic screen of the pre-push electronic price tag, the method further comprises: if the comparison result is size matching, directly storing the new information picture as the display picture of the pre-updated commodity.

The mobile terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0026] The following will be described in combination with Figure 1 The components of the mobile terminal will be described in detail:

[0027] The radio frequency unit 101 can be used for receiving and sending signals in the process of receiving or sending messages or calls. Specifically, the downlink message of the base station is received and sent to the processor 110 for processing. In addition, the uplink data is sent to the base station. Generally, the radio frequency unit 101 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier, a duplexer, etc. In addition, the radio frequency unit 101 can also communicate with the network and other devices through wireless communication.

[0028] WiFi belongs to a short-range wireless transmission technology. The mobile terminal can help users send and receive emails, browse web pages, and access streaming media through the WiFi module 102. It provides users with wireless broadband Internet access. Although Figure 1 The WiFi module 102 is shown, but it can be understood that it does not belong to the necessary components of the mobile terminal, and can be omitted as needed without changing the essence of the application.

[0029] The audio output unit 103 can convert audio data, which are received from the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109, into an audio signal and output the audio signal as sound when the mobile terminal 100 is in a call signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. Moreover, the audio output unit 103 can provide a specific function related to a particular function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, and the like). The audio output unit 103 can include a speaker, a buzzer, and the like.

[0030] The A / V input unit 104 is for receiving audio or video signals. The A / V input unit 104 can include a graphic processing unit (GPU) 1041 and a microphone 1042. The graphic processing unit 1041 processes image data of a still picture or a video obtained by an image capture device (e.g., a camera) in a video call mode or an image call mode. Processed image frames can be displayed on the display unit 106. The image frames processed by the graphic processing unit 1041 can be stored in the memory 109 (or other storage medium) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 receives a sound (audio data) in a phone call mode, a recording mode, a voice recognition mode, and the like via the microphone 1042, and can process such a sound into audio data. Processed audio (voice) data can be converted into a format transmittable to a mobile communication base station in a phone call mode and outputted via the radio frequency unit 101. The microphone 1042 can implement various types of noise removal (or cancellation) algorithms to remove (or cancel) noise generated in the process of receiving and transmitting audio signals.

[0031] The mobile terminal 100 further includes at least one sensor 105, such as a light sensor, a motion sensor, and the like. Specifically, the light sensor includes an ambient light sensor to adjust the brightness of the display panel 1061 according to the brightness of ambient light, and a proximity sensor to turn off the display panel 1061 and / or the backlight when the mobile terminal 100 approaches an ear. As one of the motion sensor, an accelerometer sensor can detect the magnitude and direction of acceleration in each of the three axes, and can be used to identify the posture of the mobile terminal 100 (e.g., a screen rotation, a game, a magnetometer posture calibration), a vibration recognition-related function (e.g., a pedometer, a knock), and the like. The mobile terminal 100 can further include a fingerprint sensor, a pressure sensor, an iris sensor, a molecular sensor, a gyroscope, a barometer, a hygrometer, a thermometer, an infrared sensor, and the like, which are not described herein.

[0033] The user input unit 107 can be configured to receive an inputted numeric or character message, and to generate a key signal input related to user settings of the mobile terminal and control of the function. Specifically, the user input unit 107 can include a touch panel 1071 and other input devices 1072. The touch panel 1071, also called a touch screen, can collect a touch operation of a user on or proximate thereto (such as an operation of the user using a finger, a stylus, or the like, or any suitable object or accessory on or proximate to the touch panel 1071), and can drive a corresponding connection device according to a pre-set program. The touch panel 1071 can include two parts, a touch detecting device and a touch controller. The touch detecting device detects a user's touch position and detects a signal resulting from the touch operation, and transmits the signal to the touch controller. The touch controller receives a touch message from the touch detecting device, converts it into a touch coordinate, and transmits it to the processor 110, and can receive a command from the processor 110 and execute it. In addition, the touch panel 1071 can be implemented in various types such as a resistive type, a capacitive type, an infrared type, and a surface acoustic wave type. In addition to the touch panel 1071, the user input unit 107 can include other input devices 1072. Specifically, the other input devices 1072 can include one or more of a physical keypad, a function key (such as a volume control button, a switch button, or the like), a trackball, a mouse, a jog, or the like, without being limited thereto.

[0034] Further, the touch panel 1071 can cover the display panel 1061, and when the touch panel 1071 detects a touch operation on or proximate thereto, it can transmit the same to the processor 110 to determine a type of the touch event, and then the processor 110 can provide a corresponding visual output on the display panel 1061 according to the type of the touch event. Although in the above-described embodiment, the touch panel 1071 and the display panel 1061 are implemented as two separate components to realize the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the mobile terminal, without being limited thereto.

The processor 110 can include one or more processing units; preferably, the processor 110 can integrate an application processor and a modem processor, where the application processor mainly processes an operating system, a user interface, and application programs, etc., and the modem processor mainly processes wireless communication. It is understood that the above-mentioned modem processor can also not be integrated into the processor 110.

[0038] The mobile terminal 100 can further include a power supply 111 (such as a battery) that supplies power to each of the components, and preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, thereby enabling the power management system to perform functions such as management of charging, discharging, and power consumption management, etc.

The communication network system is a LTE system of general mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203 and an operator's IP service 204 connected in sequence.

[0047] Based on the aforementioned mobile terminal hardware structure and communication network system, various embodiments of the method of the present invention are proposed.

[0048] Example 1

[0049] like Figure 3 As shown, Embodiment 1 of the present invention proposes a method for pushing electronic price tags, which specifically includes the following steps:

[0050] Step S110: Obtain the new information image of the product to be updated, and compare the size information of the new information image with the pre-stored size information of the electronic price tag to be pushed, and obtain the corresponding comparison result.

[0051] Specifically, the method in this embodiment of the invention is mainly applied to the following electronic shelf label system, which mainly consists of an electronic shelf label server, a gateway (main control + broadcast and data gateway), and several electronic shelf labels. The electronic shelf label server and the gateway are connected via a wired Ethernet connection, and the gateway and the electronic shelf labels communicate via a 2.4G proprietary communication protocol or other communication protocols. The electronic shelf label server is mainly used for data calculation and data communication with the gateway and electronic shelf labels to update the data information of the electronic shelf labels; the electronic shelf labels should include an independent storage medium (for storing original product information) and an electronic screen for displaying product information.

[0052] When a certain electronic shelf label in the aforementioned electronic shelf label system (that is, a pre-push electronic shelf label) needs to update the product information displayed on its electronic screen (i.e., the original product information of the product to be updated), its server will first obtain the new information image of the product to be updated, and compare the size information of the new information image with the pre-stored size information of the pre-push electronic shelf label (i.e., the electronic shelf label whose product information needs to be updated on its electronic screen) to obtain the corresponding comparison result.

[0053] Since the size information of the new information picture is compared with the pre-stored size information of the pre-push electronic price tag to obtain the corresponding comparison result in the above method steps, the server needs to perform the following method steps before performing the above method steps: receiving and saving the display size of the electronic screen of the pre-push electronic price tag reported by the pre-push electronic price tag to generate the pre-stored size information. The pre-stored size information includes the horizontal display length x of the electronic screen and the vertical display width y of the electronic screen. Correspondingly, the size information of the new information picture in the above method steps includes the horizontal length x1 of the new information picture and the vertical width y1 of the new information picture.

[0054] At this time, as shown in Figure 4 The specific process of performing the method step of "comparing the size information of the new information picture with the pre-stored size information of the pre-push electronic price tag to obtain the corresponding comparison result" is as follows:

[0055] Step S111: comparing the horizontal length of the new information picture with the horizontal display length of the electronic screen to obtain a first comparison result.

[0056] Step S112: comparing the vertical width of the new information picture with the vertical display width of the electronic screen to obtain a second comparison result.

[0057] Step S113: obtaining the corresponding comparison result according to the first comparison result and the second comparison result.

[0058] At this time, if the first comparison result and the second comparison result are both size matching, the corresponding comparison result is size matching; if any or both of the first comparison result and the second comparison result are size mismatching, the corresponding comparison result is size mismatching. That is, x and x1, y and y1 are compared respectively; when any one value is mismatching, the corresponding comparison result is size mismatching, and only when both values are matching, the corresponding comparison result is size matching.

[0059] Step S120: if the comparison result is size mismatching, performing digital image processing on the new information picture to adjust the size information of the new information picture to be matched with the pre-stored size information to obtain and store the display picture of the pre-updated commodity.

[0060] Specifically, when the comparison is performed through the method steps, and the corresponding comparison result is that the sizes do not match, then the new information picture is subjected to digital image processing, so that the size information of the new information picture is adjusted to match the pre-stored size information, to obtain the display picture of the pre-updated commodity and store it. The specific process is as follows: the image information of the new information picture is cropped or supplemented through a preset image processing algorithm, so that the size information of the new information picture is adjusted to match the pre-stored size information, and the preset image processing algorithm includes any one or any combination of the nearest neighbor interpolation method, the bilinear interpolation method, and the bicubic interpolation method.

[0061] In addition, when the comparison is performed through the method steps, and the corresponding comparison result is that the sizes match, then the new information picture is directly stored as the display picture of the pre-updated commodity.

[0062] Step S130: The display picture is pushed to the pre-push electronic price tag to be displayed on the electronic screen of the pre-push electronic price tag.

[0063] Specifically, after the server obtains the display picture of the pre-updated commodity through the method steps, the display picture can be pushed to the pre-push electronic price tag to be displayed on the electronic screen of the pre-push electronic price tag. The specific process is as follows: the display picture of the commodity is subjected to data packaging (compression or other processing) through a preset communication protocol, and then is pushed to the pre-push electronic price tag, so that the display picture is displayed on the electronic screen of the pre-push electronic price tag after being subjected to corresponding data recovery processing by the pre-push electronic price tag. The preset communication protocol is preferably a 2.4G private communication protocol.

[0064] Embodiment Two

[0065] As shown in Figure 5 Embodiment Two of the present application proposes a terminal 20, which comprises a memory 21, a processor 22, a program stored on the memory and executable on the processor, and a data bus 23 for realizing connection communication between the processor 21 and the memory 22. When the program is executed by the processor, the steps of the method for pushing the electronic price tag in Embodiment One are realized, and the details are as described above, which will not be repeated here.

[0066] It should be noted that the terminal 20 of Embodiment of the present application and the method of Embodiment One belong to the same concept, and the specific implementation process is detailed in Embodiment One, and the technical features in Embodiment One are all applicable to the terminal 20, which will not be repeated here.

[0067] Embodiment Three

[0068] Embodiment three of the present application provides a storage medium for computer readable storage, the storage medium storing one or more programs, the one or more programs being executable by one or more processors to implement the specific steps of the method of electronic price tag pushing in embodiment one.

[0069] It should be noted that the above storage medium and method embodiments belong to the same concept, and the specific implementation process is detailed in method embodiment one, and the technical features in method embodiment one are all applicable in the storage medium embodiment, which will not be repeated here.

[0070] The method, terminal and storage medium for electronic price tag pushing provided by the embodiments of the present application, when the electronic price tag needs to update the product information displayed on the electronic screen, the server end will first obtain the new information picture of the pre-updated product, and compare the size information of the new information picture with the pre-stored size information of the pre-pushed electronic price tag (i.e. the electronic price tag that needs to update the product information displayed on the electronic screen), to obtain the corresponding comparison result. When the comparison result is that the sizes do not match, the new information picture is subjected to digital image processing, so that the size information of the new information picture is adjusted to match the pre-stored size information, to obtain the display picture of the product and store it. Then the display picture is pushed to the pre-pushed electronic price tag for display on the electronic screen of the pre-pushed electronic price tag. In this way, by adaptively adjusting the size information of the new information picture carrying the product information on the server end to match the pre-stored size information of the pre-pushed electronic price tag, the corresponding pushing is performed when the sizes match, thereby effectively solving the technical problem that the existing electronic price tag pushing method is prone to compatibility problems and thus affects the user experience.

A method for pushing electronic price tags, characterized in that, The method includes the following steps: Receive and save the display size of the electronic screen of the pre-push electronic price tag reported by the pre-push electronic price tag, so as to generate pre-stored size information, wherein the pre-stored size information includes the horizontal display length and the vertical display width of the electronic screen; Obtain a new information image of the product to be updated, and compare the size information of the new information image with the pre-stored size information of the electronic price tag to be pushed, and obtain the corresponding comparison result. The size information of the new information image includes the horizontal length and the vertical width of the new information image. If the comparison result indicates a size mismatch, then digital image processing is performed on the new information image to adjust its size information to match the pre-stored size information, thereby obtaining and storing the display image of the pre-updated product. Specifically, a preset image processing algorithm is used to crop or supplement the image information of the new information image to adjust its size information to match the pre-stored size information. The preset image processing algorithm includes any one or more of nearest neighbor interpolation, bilinear interpolation, and bicubic interpolation. If the comparison result is a size match, the new information image is directly stored as the display image of the pre-updated product; The display image is pushed to the pre-push electronic price tag for display on the electronic screen of the pre-push electronic price tag. The display image of the pre-updated product is packaged and processed using a preset communication protocol and then pushed to the pre-push electronic price tag. After the pre-push electronic price tag performs the corresponding data recovery processing, the image is displayed on the electronic screen of the pre-push electronic price tag. in, The horizontal length of the new information image is compared with the horizontal display length of the electronic screen to obtain the first comparison result; The vertical width of the new information image is compared with the vertical display width of the electronic screen to obtain a second comparison result; Based on the first comparison result and the second comparison result, the corresponding comparison result is obtained; If both the first comparison result and the second comparison result are size matches, then the corresponding comparison result is a size match. If either or both of the first comparison result and the second comparison result are size mismatched, then the corresponding comparison result is a size mismatch.

2. A terminal, characterized in that, include: The method comprises a memory, a processor, a program stored in the memory and executable on the processor, and a data bus for establishing communication between the processor and the memory, wherein the program, when executed by the processor, implements the steps of the method as described in claim 1.

3. A storage medium for computer-readable storage, characterized in that, The storage medium stores one or more programs, which can be executed by one or more processors to implement the steps of the method as described in claim 1.
