[0025] FIG. 6 is a schematic diagram of a system for transmitting electronic shelf label information in an embodiment of the present invention.
[0026] FIG. 1 is a flowchart of a method for transmitting electronic shelf label information in an embodiment of the present invention. As shown in FIG. 1, the method comprises:
[0027] a step 101: adjusting a volume of to-be-displayed information which is to be displayed on an electronic shelf label according to a buffer size of the electronic shelf label, to obtain at least one to-be-displayed information block which is compatible to the buffer size so that the to-be-displayed information block can be transmitted to the electronic shelf label at one time;
[0028] a step 102: sending the at least one to-be-displayed information block to the electronic shelf label in sequence.
[0029] In the embodiment of the present invention, adjusting a volume of to-be-displayed information which is to be displayed on an electronic shelf label to obtain at least one to-be-displayed information block which is compatible to the buffer size so that the to-be-displayed information block can be transmitted to the electronic shelf label at one time. The obtained to-be-displayed information block is compatible to the buffer size of the electronic shelf label and requires less space than that of the to-be-displayed information, thereby can be sequentially sent to the electronic shelf label with higher communication efficiency.
[0030] Before the step 101, the buffer size of the electronic shelf label sent by the electronic shelf label may be obtained firstly, and then the to-be-displayed information may be obtained. The to-be-displayed information may include prices, production places, brands, and other data related to products on sale. Due to different screen sizes of the electronic shelf labels, different to-be-displayed information may also have different sizes with a variation of about a thousand bytes to tens of thousands bytes. However, a MCU (Micro Control Unit) inside the electronic shelf label has limited storage space, and different MCUs may have different storage spaces. To adapt to a plurality of MCUs with different storage spaces and plenty of to-be-displayed information with different sizes, the electronic shelf label may send a size of space in its memory that can be utilized as a buffer through heartbeat data. Then in the step 101, adjusting a volume of to-be-displayed information which is to be displayed on an electronic shelf label according to a buffer size of the electronic shelf label, to obtain at least one to-be-displayed information block which is compatible to the buffer size so that the to-be-displayed information block can be transmitted to the electronic shelf label at one time. The obtained to-be-displayed information block is compatible to the buffer size of the electronic shelf label and requires less space than that of the to-be-displayed information, thereby can be sequentially sent to the electronic shelf label in the step 102 with higher communication efficiency. The to-be-displayed information block may have many forms, among which the picture is a common form. The to-be-displayed information may be a to-be-displayed picture. The size adjustment of the to-be-displayed picture of the electronic shelf label is a procession to the to-be-displayed picture to obtain a plurality of to-be-displayed information blocks, and the size of each to-be-displayed information block is smaller than or equal to the buffer size of the electronic shelf label. So the at least one to-be-displayed information block can be successfully transmitted to the buffer space in sequence.
[0031] In a specific implementation, there are many methods for adjusting the volume of the to-be-displayed information according to the buffer size of the electronic shelf label to obtain at least one to-be-displayed information block which is compatible to the buffer size, among which a method in an embodiments will be given below.
[0032] Adjusting the volume of the to-be-displayed information according to the buffer size of the electronic shelf label to obtain at least one to-be-displayed information block which is compatible to the buffer size, comprising:
[0033] determining whether a segmentation and compression process on the to-be-displayed information is necessary from the buffer size of the electronic shelf label and the volume of the to-be-displayed information;
[0034] obtaining a plurality of compressed packages of the to-be-displayed information which conform to the buffer size of the electronic shelf label, if it is determined that the segmentation and compression process is necessary;
[0035] obtaining one compressed package of the to-be-displayed information which is compatible to the buffer size of the electronic shelf label, if it is determined that the segmentation and compression process is not necessary.
[0036] In the above-described embodiment, a case where the buffer size of the electronic shelf label is smaller than the volume of the to-be-displayed information has been taken into account. For example, the buffer size of the electronic shelf label is only 4 Kbytes, while the volume of the to-be-displayed information (e.g., the to-be-displayed picture) is 10 Kbytes. Then determining whether a segmentation and compression process on the to-be-displayed information is necessary from the buffer size of the electronic shelf label and the volume of the to-be-displayed information. When the buffer size of the electronic shelf label is smaller than the volume of the to-be-displayed information, the segmentation and compression process is necessary and a plurality of compressed packages of the to-be-displayed information compatible to the buffer size of the electronic shelf label need to be obtained. In other words, the to-be-displayed information blocks compatible to the buffer size of the electronic shelf label are a plurality of the compressed packages. For example, when the buffer size of the electronic shelf label is only 4 Kbytes, and the volume of the to-be-displayed information is 10 Kbytes, three compressed packages of the to-be-displayed information compatible to the buffer size of the electronic shelf label need to be obtained.
[0037] When the buffer size of the electronic shelf label is not smaller than the volume of the to-be-displayed information, the segmentation and compression process is not necessary, and only one compressed package of the to-be-displayed information compatible to the buffer size of the electronic shelf label need to be obtained.
[0038] By obtaining the at least one compressed package, the volume of the to-be-displayed information can be further reduced, and the communication efficiency that the to-be-displayed information transmitted to the electronic shelf label can be further improved.
[0039] In an embodiment, before determining whether the segmentation and compression process on the to-be-displayed information is necessary from the buffer size of the electronic shelf label and the volume of the to-be-displayed information, the method further comprises:
[0040] determining whether a differentiation process on the to-be-displayed information is necessary, and performing the differentiation process on the to-be-displayed information if it is determined that the differentiation process is necessary;
[0041] wherein determining whether the segmentation and compression process on the to-be-displayed information is necessary from the buffer size of the electronic shelf label and the volume of the to-be-displayed information comprises:
[0042] determining whether a segmentation and compression process on the to-be-displayed information on which the differentiation process has been performed is necessary from the buffer size of the electronic shelf label and the volume of the to-be-displayed information on which the differentiation process has been performed.
[0043] In the above-described embodiment, a case where some information stored in the electronic shelf label is similar to the to-be-displayed information has been taken into account. In this case, a differentiation process on the to-be-displayed information of the electric shelf label may be performed to further reduce the volume of the to-be-displayed information, thereby further improving the communication efficiency of transmitting the to-be-displayed information to the electronic shelf label. Thereafter, determining whether the segmentation and compression process on the to-be-displayed information on which the differentiation process has been performed is necessary from the buffer size of the electronic shelf label and the volume of the to-be-displayed information on which the differentiation process has been performed.
[0044] In an embodiment, determining whether the differentiation process on the to-be-displayed information is necessary, and performing the differentiation process on the to-be-displayed information if it is determined that the differentiation process is necessary, comprising:
[0045] obtaining a stored picture of the electronic shelf label;
[0046] generating a to-be-displayed picture of the electronic shelf label and a keyword of the to-be-displayed picture from the to-be-displayed information;
[0047] determining whether the differentiation process on the to-be-displayed picture is necessary from a keyword of the stored picture and the keyword of the to-be-displayed picture; and
[0048] performing the differentiation process on the to-be-displayed picture of the electronic shelf label according to the stored picture of the electronic shelf label, if it is determined that the differentiation process is necessary.
[0049] In the embodiment described above, the stored picture of the electronic shelf label may not be sent by the electronic shelf label and may be obtained by other means. For example, the information transmission method of the electronic shelf label may be performed by a server communicatively coupled to the electronic shelf label. The server may be communicatively coupled to a plurality of the electronic shelf labels. The server may receive the buffer size of the electronic shelf label sent by the electronic shelf label and send at least one to-be-displayed information block compatible to the buffer size of the electronic shelf label to the electronic shelf label. That is, before being received by the electronic shelf label, the stored picture as the to-be-displayed information has been sent to the electronic shelf label by the server, so it has been recorded in the server and can be obtained from the server.
[0050] In general, the information stored in the electronic shelf label is usually pictures. Accordingly, the to-be-displayed picture is generated from the to-be-displayed information for being sent to the electronic shelf label. It should be appreciated that the to-be-displayed information may also be in other forms, such as character strings compatible to a preset rule. The corresponding electronic shelf label can display the character strings compatible to the preset rule according to the template of the electronic shelf label. Although embodiments of the to-be-displayed information being pictures have been provided, other alternations made by those skilled in the art shall fall within the scope of the invention.
[0051] To compare the to-be-displayed picture with the stored picture stored in the electronic shelf label, a keyword of the to-be-displayed picture may need to be generated according to the to-be-displayed information. Then determining whether the differentiation process on the to-be-displayed picture is necessary form a keyword of the stored picture and the keyword of the to-be-displayed picture. The categories of the keyword of the to-be-displayed picture and the stored picture may be various and may include prices and appearances. If the keyword of the stored picture is consistent with that of the to-be-displayed picture, the differentiation process is necessary. The differentiation process on the to-be-displayed picture according to the stored picture of the electronic shelf label is subtracting the corresponding pixel values of the to-be-displayed picture and the stored picture to weaken the similar portions of the two pictures and highlight the different portions of the two pictures. The to-be-displayed picture subjected to the differentiation process has a smaller size and can be sent to the electronic shelf label only with information different from the stored picture of the electric shelf label, thereby significantly improving communication efficiency. The electronic shelf label can achieve the to-be-displayed picture by an inverse differentiation process. If the keyword of the stored picture of the electronic shelf label is not consistent with that of the to-be-displayed picture, the differentiation process on the to-be-displayed picture is not necessary.
[0052] In a specific implementation, the electronic shelf label may obtain at least one to-be-displayed information block, e.g., a plurality of compressed packages of a to-be-displayed picture, by receiving the to-be-displayed information. The server performing the information transmission method of the electronic shelf label may send display control information to the electronic shelf label to perform a control to the electronic shelf label to display the picture.
[0053] Therefore, in an embodiment, the method for transmitting electronic shelf label information may further comprise: sending display control information to the electronic shelf label.
[0054] In the above embodiment, the display control information of the electronic shelf label may be an identifier of the picture of the electronic shelf label.
[0055] In the method of transmitting electronic shelf label information provided in the embodiments of the invention, the to-be-displayed information block compatible to the buffer size of the electronic shelf label can be obtained by adjusting the volume of the to-be-displayed information according to the buffer size of the electronic shelf label. The obtained to-be-displayed information block is compatible to the buffer size of the electronic shelf label and requires less space than that of the to-be-displayed information before adjusting, thereby can be sequentially sent to the electronic shelf label with higher communication efficiency. The electronic shelf label may store a received to-be-displayed information block in its memory and then receive the next to-be-displayed information block.
[0056] In addition, the to-be-displayed picture has a smaller size by the differentiation process, and can be sent to the electric shelf label only with information different from the stored picture of the electric shelf label, thereby significantly improving communication efficiency. By obtaining at least one compressed package, the size of space required by the to-be-displayed information to display can be further reduced, and the communication efficiency can be further improved.
[0057] FIG. 2 is flowchart of a method for transmitting electronic shelf label information in another embodiment of the present invention. As shown in FIG. 2, the method comprises:
[0058] a step 201: if at least one to-be-displayed information block compatible to a buffer size of an electronic shelf label is at least one compressed package of a to-be-displayed picture, performing the following steps iteratively for each compressed package of the to-be-displayed picture until all of the at least one compressed package is received: receiving the compressed package; storing the compressed package in a memory of the electronic shelf label; and releasing a buffer of the electronic shelf label; wherein the at least one to-be-displayed information block compatible to the buffer size of the electronic shelf label is obtained by adjusting a volume of to-be-displayed information which is to be displayed on the electronic shelf label according to the buffer size of the electronic shelf label, so that the to-be-displayed information block can be transmitted to the electronic shelf label at one time; and
[0059] a step 202: performing a decompression process on the at least one compressed package in the buffer of the electronic shelf label to obtain the to-be-displayed picture.
[0060] The memory used in the step 201 may be a non-transitory memory to realize reliable data storage.
[0061] Before the step 201, the electronic shelf label may send out a size of a storage space of the electronic shelf label. For example, the electronic shelf label may send the size of the storage space to a server communicatively coupled to the electronic shelf label. Then the electronic shelf label receives the at least one to-be-displayed information block compatible to the buffer size of the electronic shelf label according to the step 201. Wherein the at least one to-be-displayed information block is obtained by adjusting the volume of the to-be-displayed information according to the buffer size of the electronic shelf label, and the specific adjustment method may be the steps 101 to 102 in the embodiment described above. The at least one to-be-displayed information block sent by the server may be a plurality of compressed packages. Accordingly, in the step 201, determining whether the to-be-displayed information block compatible to the buffer size of the electronic shelf label is at least one compressed package of the to-be-displayed picture, and if the at least one to-be-displayed information block is at least one compressed package, performing the following steps iteratively for each compressed package until all of the at least one compressed package is received: receiving the compressed package; storing the compressed package in a memory (such as Flash) of the electronic shelf label; and releasing the buffer of the electronic shelf label.
[0062] By iteratively executing the above steps, all of the at least one compressed package can be received in sequence, and then in the step 202, performing the decompression process on the at least one compressed package in the buffer of the electronic shelf label to obtain the to-be-displayed picture. The electronic shelf label is in a standby mode except when receiving the to-be-displayed information block to reduce its power consumption, which is a tradeoff between reducing power consumption of chips and improving communication efficiency.
[0063] In specific implementation, if the to-be-displayed picture that has been subjected to a differentiation process, a complete to-be-displayed picture needs to be obtained by a method in the following embodiment.
[0064] In an embodiment, the method for transmitting electronic shelf label information further comprises:
[0065] performing, if the obtained to-be-displayed picture has been subjected to a differentiation process, an inverse differentiation process on the to-be-displayed picture according to a picture stored in the electronic shelf label.
[0066] In the above embodiment, an inverse differentiation process on the to-be-displayed picture is recovering all information of the to-be-displayed picture from the keyword of the to-be-displayed picture and the stored picture of the electronic shelf label.
[0067] In specific implementation, the electronic shelf label receives the to-be-displayed information and displays the to-be-displayed picture according to display control information.
[0068] In an embodiment, the method for transmitting electronic shelf label information further comprises:
[0069] receiving display control information for electronic shelf label; and
[0070] displaying the stored picture in the electronic shelf label according to the display control information.
[0071] In the above embodiment, the electronic shelf label may receive the display control information from a server, and the display control information may be an identifier of the to-be-displayed information (e.g., the to-be-displayed picture).
[0072] In the method of transmitting electronic shelf label information provided in the embodiments of the invention, if at least one to-be-displayed information block compatible to a buffer size of an electronic shelf label is at least one compressed package of a to-be-displayed picture, performing the following steps iteratively for each compressed package of the to-be-displayed picture until all of the at least one compressed package is received: receiving the compressed package; storing the compressed package in a memory of the electronic shelf label; and releasing a buffer of the electronic shelf label; wherein the at least one to-be-displayed information block compatible to the buffer size of the electronic shelf label is obtained by adjusting a volume of to-be-displayed information which is to be displayed on the electronic shelf label according to the buffer size of the electronic shelf label, so that the to-be-displayed information block can be transmitted to the electronic shelf label at one time; and
[0073] performing a decompression process on the at least one compressed package in the buffer of the electronic shelf label to obtain the to-be-displayed picture.
[0074] Therefore, the buffer size of the electronic shelf label has been taken into account and each of the compressed package is received after the buffer of the electronic shelf label has been released, thereby improving communication efficiency. In addition the electronic shelf label is in a standby mode except when receiving the to-be-displayed information block to reduce its power consumption.
[0075] Based on the same inventive concept as the method for transmitting electronic shelf label information, an embodiment of the present invention further provides a server as described below. Since the principle of solving problems is similar to that of the method for transmitting electronic shelf label information, the implementation of the server can be referred to that of the method as described above, and the repetition will not be described in detail.
