Referring to fig. 1 and 2, an embodiment of the present invention provides an information interaction method. The information interaction method is used for the gateway apparatus 200, and the information interaction method may be implemented by the gateway apparatus 200. The gateway apparatus 200 may not be dedicated to implementing the information interaction method according to the embodiment of the present invention, but may implement other functions and methods. In some embodiments, the information interaction method includes:
step S10A, under the condition that a data transmission instruction is received, acquiring wake-up time of a plurality of electronic shelf labels 100, wherein the electronic shelf labels 100 are in a wake-up state in the wake-up time;
step S20A, determining a preset time interval according to the wake-up time of the plurality of electronic shelf labels 100;
step S30A, a first data packet is sent to the plurality of electronic shelf labels 100 in a wireless broadcast manner at predetermined time intervals, so that the plurality of electronic shelf labels 100 receive the first data packet in an awake state.
The gateway device 200 supports Periodic broadcasting with responses (Periodic ADVERTISING WITH Responses, PAwR). The gateway apparatus 200 may transmit the first data packet to the plurality of electronic shelf labels 100 in a wireless broadcast manner at predetermined time intervals so that the electronic shelf labels 100 update information of the electronic shelf labels. The gateway device 200 does not need to establish a connection with the electronic shelf label 100 one by one, and power consumption of the gateway device 200 is reduced. The predetermined time interval may be determined according to wake-up times of the plurality of electronic shelf labels 100, so as to ensure that the electronic shelf labels 100 receive the first data packet in the wake-up state, so that the electronic shelf labels 100 can update the displayed information according to the first data packet. The electronic shelf label 100 can be in a dormant state for a period of time, and be in an awake state for a period of time, and the electronic shelf label 100 is not in the awake state for a long time, so that the power consumption of the electronic shelf label 100 is reduced.
Optionally, the gateway device 200 includes a first acquisition module, a determination module, and a first sending module. The first obtaining module may perform the step S10A, the determining module may perform the step S20A, and the first sending module may perform the step S30A.

The electronic shelf label 100 and the gateway device 200 may be provided in the same device. For example, the electronic shelf label 100 and the gateway device 200 may both be disposed within a computer device, and the electronic shelf label 100 may be an electronic display screen of the computer device. The electronic shelf label 100 and the gateway device 200 may also be provided in different devices. For example, the electronic shelf label 100 may be disposed on a commodity counter, and the gateway device 200 may be disposed in a computer.
The gateway device 200 may enable data transfer between a host computer and the electronic shelf label 100. The computer host issues a data transmission instruction to the gateway device 200, the gateway device 200 sends a first data packet to the electronic shelf label 100 according to the data transmission instruction, and the electronic shelf label 100 displays corresponding content on the electronic shelf label according to the received first data packet.
Gateway device 200 may be communicatively coupled to a plurality of electronic shelf labels 100 based on the protocol of bluetooth 5.4. The gateway device 200 supports Periodic broadcasting with responses (Periodic ADVERTISING WITH Responses, PAwR). The gateway device 200 may periodically transmit the first data packet to the plurality of electronic shelf labels 100 in a wireless broadcast manner, without establishing a connection with the electronic shelf labels 100 one by one, thereby reducing power consumption of the gateway device 200.
The plurality of electronic shelf labels 100 may be in a dormant state for a period of time and in an awake state for a period of time. The power consumption of the electronic shelf label 100 in the awake state is greater than the power consumption of the electronic shelf label 100 in the sleep state. In the case where the electronic shelf label 100 is in the awake state, the electronic shelf label 100 may update information of the electronic shelf label according to the received first data packet. When the electronic shelf label 100 is in the sleep state, the electronic shelf label 100 does not update information of the electronic shelf label according to the received first data packet.
In step S10A and step S20A, in the case where the gateway apparatus 200 receives the data transmission instruction, the gateway apparatus 200 may acquire the wake-up times transmitted by the plurality of electronic shelf labels 100 and determine the predetermined time interval according to the wake-up times of the plurality of electronic shelf labels 100. The wake-up time transmitted by the plurality of electronic shelf labels 100 may be a plurality of time periods, respectively, and the gateway apparatus 200 determines the predetermined time interval T0 according to the plurality of time periods. Wherein, the Ta-Tb time period may be a wake-up time period of one electronic shelf label 100, and the Tc-Td time period may be a wake-up time period of another electronic shelf label 100. The predetermined time interval T0 may be set to an absolute value less than Ta-Tc and less than Tb-Td to ensure that the plurality of electronic shelf labels 100 may receive the first data packet within the wakeup period.
The wake-up time sent by one electronic shelf label 100 may also be multiple time periods. For example, the Ta-Tb period and the Tc-Td period may be wake-up periods of one electronic shelf label 100. The Te-Tf period may be a wake-up period of another electronic shelf label 100. The predetermined time interval T0 may be set to be less than the absolute value of Ta-Tc and less than the absolute value of Tb-Td, and the predetermined time interval T0 may also be set to be less than the absolute value of Ta-Te and less than the absolute value of Tb-Tf to ensure that the plurality of electronic shelf labels 100 can receive the first data packet within the wakeup period.
In step S30A, at the determined time interval T0, the gateway apparatus 200 may transmit the first data packet to the plurality of electronic shelf labels 100 in a wireless broadcast manner to the plurality of electronic shelf labels 100 at the time interval T0, the gateway apparatus 200 may simultaneously transmit the first data packet to the plurality of electronic shelf labels 100, and the plurality of electronic shelf labels 100 may receive the first data packet in the wake-up time.
Alternatively, the gateway device 200 may send the first data packet to the N electronic shelf labels 100, and the M electronic shelf labels 100 may receive the first data packet in the wake-up time. M may be equal to N, i.e., all electronic shelf labels 100 receive the first data packet in the wake-up time. M may also be less than N, i.e., a portion of electronic shelf label 100 receives the first data packet during the wake-up time and another portion does not receive the first data packet during the wake-up time.
The electronic shelf label 100 may receive the first data packet in the wake-up time and update information of the electronic shelf label according to the received first data packet. The electronic shelf label 100 can be in a dormant state for a period of time, and be in an awake state for a period of time, and the electronic shelf label 100 is not in the awake state for a long time, so that the power consumption of the electronic shelf label 100 is reduced.
Referring to fig. 2 and 3, the embodiment of the invention further provides an information updating method. The information updating method is used for the electronic shelf label 100, and the information updating method can be implemented by the electronic shelf label 100. The electronic shelf label 100 may not be dedicated to the implementation of the information updating method according to the embodiment of the present invention, but may implement other functions and methods. In some embodiments, the information updating method includes:
step S10B, a wake-up time is sent to the gateway equipment 200, wherein the wake-up time is the time when the electronic shelf label 100 is in a wake-up state;
Step S20B, acquiring a first data packet transmitted by the gateway apparatus 200 in a wireless broadcast manner at a predetermined time interval, where the predetermined time interval is determined by the gateway apparatus 200 according to the wake-up times of the plurality of electronic shelf labels 100;
And step S30B, updating information displayed by the electronic shelf label according to the first data packet.
Alternatively, in step S10B, the electronic shelf label 100 may transmit a wake-up time to the gateway apparatus 200 according to its own situation. For example, the wake-up time sent by the electronic shelf label 100 with the larger power may be longer, and the wake-up time sent by the electronic shelf label 100 with the smaller power may be shorter.
The electronic shelf label 100 may also alter the wake-up time sent to the gateway device 200 when a change occurs in the condition of the electronic shelf label 100 itself. For example, the charger may charge the electronic shelf label 100 with a smaller amount of power. The less charged electronic shelf label 100 may change the wake-up time sent to the gateway device 200 when entering the charging state.
After step S10B, the gateway apparatus 200 starts to perform steps S10A to S30A, and the gateway apparatus 200 performs steps S10A to S30A may refer to the above-described embodiments.
After the gateway apparatus 200 performs step S10A to step S30A, the electronic shelf label 100 starts to perform step S20B and step S30B. In the wake-up state of the electronic shelf label 100, the received first data packet may be a first data packet for drawing, and the electronic shelf label 100 may update information of the electronic shelf label according to the first data packet for drawing.
For example, the electronic display screen may be communicatively connected to the gateway device 200 based on the bluetooth 5.4 protocol, and in the awake state, the electronic display screen may receive the first data packet for drawing sent by the gateway device 200, and update the display content of the electronic display screen according to the first data packet for drawing. The electronic shelf label 100 arranged on the shelf can be in communication connection with the gateway device 200 based on the Bluetooth 5.4 protocol, and the electronic shelf label 100 can receive the first data packet of the map sent by the gateway device 200 in the wake-up state, and update the commodity information displayed by the electronic shelf label 100 according to the first data packet of the map. The electronic display screen can be in a dormant state for a period of time and in an awake state for a period of time, and is not in the awake state for a long time, so that the power consumption is reduced.
Referring to fig. 4 and 5, the interactive system 1000 may include an electronic shelf label registration phase, a swipe confirmation phase, and a data transfer phase. In the electronic shelf label 100 registration phase, there is no binding information when the electronic shelf label 100 leaves the factory, so the electronic shelf label 100 needs to bind gateway information and complete registration. After the electronic shelf label 100 completes registration, the gateway apparatus 200 replies to the electronic shelf label 100 and provides a packet number to the electronic shelf label 100.
In some embodiments, gateway apparatus 200 may perform an information interaction method comprising:
Step S01A, acquiring a registration request of the electronic shelf label 100;
Step S02A, determining whether the electronic shelf label 100 is matched with the gateway equipment 200 according to the registration request;
in step S03A, when the registration request determines that the electronic shelf label 100 matches the gateway device 200, the packet number of the electronic shelf label 100 is configured.
In some embodiments, the electronic shelf label 100 may perform an information updating method comprising:
Step S01B, a registration request is sent to the gateway apparatus 200;
In step S02B, a fourth feedback signal sent by the gateway device 200 is obtained, where in the case where the electronic shelf label 100 matches the gateway device 200, the fourth feedback signal is used to configure a packet number of the electronic shelf label 100, and the gateway device 200 is used to send a second data packet to the electronic shelf label 100 according to the packet number.
Alternatively, in step S01B, the electronic shelf label 100 may transmit a registration request to the gateway apparatus 200 by transmitting a broadcast packet. The electronic shelf label 100 after power-on will periodically send a broadcast packet to the surrounding, where the broadcast packet may include an equipment manufacturer ID, current version information, battery power information, and other customizable broadcast information.
Specifically, the broadcast packet format sent by the electronic shelf label 100 may be "packet length+device vendor id+device serial number+behavior information+version information+battery power+reservation information". The behavior information sent by the electronic shelf label 100 is search registration, and since the electronic shelf label 100 has just shipped, the version information may be default 0x00. The additional verification information may correspond to a verification manner adopted by the electronic shelf label 100, for example, a timer or a verification code is adopted to verify the electronic shelf label 100.
In step S01A-step S03A, the gateway apparatus 200 may acquire the electronic shelf label 100 to transmit the broadcast packet and analyze the broadcast packet. The electronic shelf label 100 may be grouped and the group number of the electronic shelf label 100 may be configured according to whether the device is a product of itself or a product of a partner by analyzing the device vendor ID transmitted from the electronic shelf label 100, if yes, that is, if the electronic shelf label 100 and the gateway device 200 are matched.
In the case where it is determined that the electronic shelf label 100 and the gateway device 200 are matched, the gateway device 200 may transmit a fourth feedback signal, which may be a data packet, and the data packet format may be "data packet length+gateway id+device vendor id+device serial number+behavior information+version information+device id+binding mode". The behavior information sent by the gateway device 200 is "ID assignment", and the version information may be arbitrarily set according to the requirement of the issued data. The binding mode is a binding mode of the gateway and the electronic shelf label 100, and can comprise code scanning binding and manual binding, wherein the code scanning binding is suitable for binding the electronic shelf label 100 in a small scale, the code scanning binding is used for photographing and identifying the electronic shelf label 100, and the identified electronic shelf label 100 is transmitted to the gateway equipment 200 through the code scanning. Manual binding may import the shelf good map and the map of the corresponding label into gateway device 200 to effect the binding. The device ID may include information of the electronic shelf label 100, such as detailed information of the kind of display price, specific commodity name, and the like. The packet number of the electronic shelf label 100 may be determined according to the device ID of the electronic shelf label 100.
In step S02B, after the electronic shelf label 100 completes binding with the gateway device 200, the device ID completed data packet may be rewritten to the gateway, and the format of the transmitted data packet may be "data packet length+device vendor id+device id+behavior information+version information", where the behavior information is "registration completion reply". The device ID is a device ID that the gateway device 200 pushes to the electronic shelf label 100, and the electronic shelf label 100 writes the device ID into its own memory, and can determine the packet number of the electronic shelf label 100 from the device ID of the electronic shelf label 100.
When the electronic shelf label 100 works abnormally, for example, when the time for writing the device ID into the electronic shelf label 100 is over, or when the electronic shelf label 100 is weak and cannot be connected with the gateway device 200 in a communication manner, the behavior information of the electronic shelf label 100 for transmitting the data packet to the gateway device 200 is "device abnormality code", which indicates that the electronic shelf label 100 fails to bind with the gateway device 200.
Referring to fig. 4 and 6, after the electronic shelf label registration phase, the workflow of the interactive system 1000 enters a swipe confirmation phase.
In some embodiments, after step S03A, the gateway apparatus 200 may perform an information interaction method including:
Step S04A, acquiring a group number of each electronic shelf label 100, wherein a plurality of electronic shelf labels 100 correspond to one group number;
step S05A, the second data packet is sent to the electronic shelf labels 100 with the same packet number.
In step S04A and step S05A, the gateway apparatus 200 may transmit the second data packet according to the packet number of the electronic shelf label 100. The gateway device 200 can synchronously send the periodic broadcast signal to all electronic shelf labels 100 of a certain group number, without performing communication connection to all electronic shelf labels 100 of a group number one by one, thereby reducing the power consumption of the gateway device 200. The gateway apparatus 200 transmits a second packet to the electronic shelf label 100 of the same packet number and waits for the electronic shelf label 100 to respond.
Alternatively, the packet format of the second packet sent by the gateway device 200 may be "packet length+gateway id+device id+behavior information+total packet number+version information", where the behavior information is "map brushing+first packet number", and the version information is used to check the current electronic shelf label 100 display information version.
In some embodiments, after step S05A, the gateway apparatus 200 may include:
Step S06A, obtaining first feedback signals of a plurality of electronic shelf labels 100;
Step S07A, determining whether the electronic shelf label 100 replies to the second data packet according to the first feedback signal;
Step S08A, determining the electronic shelf label 100 as the brush-drawing electronic shelf label 100 when the electronic shelf label 100 receives the second data packet;
the above-described step S10A to step S30A are performed according to the brush electronic shelf label 100.
In some embodiments, after step S02B, the information updating method includes:
step S03B, obtaining a second data packet sent by the gateway equipment 200;
In the case where it is determined to reply to the second packet, the above-described step S10B-step S30B is performed, and the wake-up time of the electronic shelf label 100 is transmitted to the gateway apparatus 200.
In step S03B, after the electronic shelf label 100 receives the second data packet of the gateway apparatus 200, the electronic shelf label 100 may reply to the gateway apparatus 200 according to its own operation condition. The packet format replied by the electronic shelf label 100 may be "packet length+device id+gateway id+behavior information+version information", and in the case where the electronic shelf label 100 determines that the second packet can be received, the behavior information replied by the electronic shelf label 100 is "open reception".
In step S06A to step S08A, when the behavior information returned from the electronic shelf label 100 is "on reception", the electronic shelf label 100 is determined to be the brush electronic shelf label 100.
After the gateway device 200 determines the electronic shelf label 100 for brushing, the gateway device 200 may determine the wake-up time of the plurality of electronic shelf labels 100 for brushing, and determine a predetermined time interval according to the wake-up time of the electronic shelf label 100 for brushing, and send the first data packet for brushing to the plurality of electronic shelf labels 100 at the predetermined time interval, which may refer to the above steps S10A-S30A for specific embodiments.
In the case that the electronic shelf label 100 determines that the second data packet is received, the electronic shelf label 100 may report the wake-up time to the gateway device 200, and update the information of the electronic shelf label according to the first data packet of the map sent by the gateway device 200, and the specific embodiment may refer to the above step S10B-step S30B.
In some embodiments, when the electronic shelf label 100 does not receive the second data packet, the electronic shelf label 100 is determined to be an abnormal electronic shelf label 100, and the abnormal electronic shelf label 100 is reported.
In step S03B, when the electronic shelf label 100 itself cannot recover the second data packet due to the write timeout, insufficient power, weak signal, identical version information, or the like, the behavior information recovered by the electronic shelf label 100 is "abnormal code".
In step S06A to step S08A, when the behavior information returned from the electronic shelf label 100 is the "abnormal code", the electronic shelf label 100 is determined to be the abnormal electronic shelf label 100. The gateway device 200 may report the abnormal electronic shelf label 100 to a corresponding server, so that a technician may find the corresponding abnormal electronic shelf label 100 for processing.
Referring to fig. 4 and 7, after the swipe confirmation phase, the workflow of the interactive system 1000 enters the data transfer phase.
In some embodiments, after step S30A, the information interaction method includes:
step S40A, obtaining a second feedback signal of the electronic shelf label 100;
Step S50A, determining a first data packet received by the electronic shelf label 100 according to a second feedback signal, wherein a plurality of first data packets are used for forming a first data packet group;
Step S60A, under the condition that the electronic shelf label 100 does not receive all the first data packets of the first data packet group, determining that the electronic shelf label 100 is a packet-loss electronic shelf label 100, and determining that the first data packets which are not received by the packet-loss electronic shelf label 100 are packet-loss data packets;
step S70A, a packet loss packet is sent to the packet loss electronic shelf label 100.
The gateway apparatus 200 transmits the first data packets to the electronic shelf label 100 at predetermined time intervals for a plurality of times, and the plurality of first data packets may form a first data packet group, and each first data packet group may be bound with a sequence number by the server for use when packet padding is lost.
The first data packet format transmitted by the gateway apparatus 200 may be "first data packet length+gateway id+apparatus id+behavior information+map brushing packet sequence number+map brushing packet", the behavior information being "data transmission".
In step S40A and step S50A, the electronic shelf label 100 may receive the first data packet transmitted by the gateway apparatus 200 during the wake-up time, and in the case where the gateway apparatus 200 has transmitted all the first data packets of the first data packet group, the electronic shelf label 100 may transmit a second feedback signal to the gateway apparatus 200to feed back the case where the electronic shelf label 100 receives the first data packet.
In the case where the electronic shelf label 100 receives all the first data packets of one first data packet group, the format of the data packet representing the second feedback signal may be "packet length+device id+gateway id+behavior information", the behavior information is "reception complete", and the gateway device 200 may determine that the electronic shelf label 100 receives all the first data packets of one first data packet group.
In step S60A and step S70A, when the electronic shelf label 100 does not receive all the first data packets of one first data packet group, the format of the data packet representing the second feedback signal may be "data packet length+gateway id+device id+behavior information+packet loss sequence number+packet loss content", the behavior information is "packet padding", and the "packet loss sequence number+packet loss content" may be the sequence number and the content corresponding to the packet loss data packet. The "packet loss sequence number+packet loss content" may be determined according to "packet number+packet refresh" in the first data packet received by the electronic shelf label 100.
For example, the corresponding packet number of the first packet in the first packet group is 1-N, and the packet number of the first packet received by the electronic shelf label 100 is 1-N-1, it may be determined that the first packet with the packet number N is a packet loss packet.
The gateway device 200 may determine a packet loss data packet according to the "packet loss sequence number+packet loss content" in the first data packet, determine the packet loss electronic shelf label 100 according to the "device id+behavior information", and send the packet loss data packet to the packet loss electronic shelf label 100.
After the packet-loss electronic shelf label 100 receives the packet-loss data packet, the packet-loss electronic shelf label 100 may feed back behavior information of "reception completion" to the gateway device 200, which indicates that all the first data packets of one first data packet group are received by the electronic shelf label 100.
In some embodiments, the interactive system 1000 may set different schemes for updating the electronic shelf label according to actual requirements. For example, the data of the first data packet may be switched according to the service type, and different values may be used to distinguish between behavior information, such as updating the full graph, updating the base graph, and updating the valid data.
The image may be composed of a plurality of layers, wherein the base map may be a layer that is placed at the bottom of the plurality of layers during the patterning process. A full picture may be all layers of an image.
When the whole image needs to be updated, the first data packet of the whole image can be provided by the gateway device 200, and the computer software can convert the original image data into data capable of being transmitted by processing the original image data and then push the data to the electronic shelf label 100 for pattern updating.
When the base map needs to be updated, the gateway device 200 may transmit the base map data to the electronic shelf label 100, and the electronic shelf label 100 updates the base map portion.
When the valid data needs to be updated, the gateway device 200 may send the valid data, such as price information and article information, the base map portion is stored in the memory of the electronic shelf label 100, and after the electronic shelf label 100 receives the valid data of the gateway device 200, the electronic shelf label 100 may perform the package packing process on the valid data and the base map portion sent by the gateway.
Referring to fig. 8, the gateway apparatus 200 may also implement a positioning function for the electronic shelf label 100 based on bluetooth 5.1.
In some embodiments, the gateway apparatus 200 may further perform an information interaction method, including:
acquiring third feedback signals of the plurality of electronic shelf labels 100, wherein the third feedback signals are determined based on shelf positions corresponding to the electronic shelf labels 100;
Determining a plurality of shelf locations corresponding to the plurality of electronic shelf labels 100 based on the plurality of third feedback signals;
acquiring a mapping relation between a goods shelf position and goods;
the positions of the plurality of products corresponding to the plurality of electronic shelf labels 100 are determined based on the shelf positions and the mapping relationship.
After the electronic shelf label 100 is started, the electronic shelf label is placed on a shelf, and based on the positioning function of bluetooth 5.1, the gateway device 200 can obtain shelf positions and shelf layout diagrams corresponding to a plurality of electronic shelf labels 100. After the commodity placement diagram is imported into the gateway device 200, the gateway device 200 may determine a mapping relationship between the shelf positions and the commodities, and implement binding of the commodity information and the price tag information, so as to obtain positions of a plurality of commodities corresponding to the shelf positions.
For example esl1 may correspond to a shelf layout and th1 may correspond to a merchandise layout. The goods shelf in the goods shelf layout chart and the goods in the goods shelf layout chart have a mapping relation. The gateway device 200 may determine the mapping relationship between each shelf and each commodity by importing the commodity placement diagram and the shelf placement diagram.
Taking the x-axis and z-axis as an example, the coordinate locations of the three shelves within the shelf layout diagram may be esl1 (x 1, z 1), esl1 (x 2, z 2), and esl1 (x 3, z 3). After determining the mapping relationship between each shelf and each commodity, three commodity coordinate positions th1 (X1, Z1), th1 (X2, Z2) and th1 (X3, Z3) corresponding to the coordinate positions esl1 (X1, Z1), esl1 (X2, Z2) and esl1 (X3, Z3) of the three shelves can be determined, so that the commodity is positioned.
Further, after the gateway device 200 binds the electronic shelf label 100, the location of each commodity may be determined according to the shelf location corresponding to the electronic shelf label 100.
Referring to fig. 9, the bluetooth 5.1 based positioning function may implement a supermarket item guiding function. For example, when the user needs to query the commodity location, the user may scan the code or open the binding between the corresponding application software and the corresponding shelf location of the electronic shelf label 100, and after the binding is completed, the user may query the commodity location on the interface.
After the user opens the Bluetooth use permission through the mobile phone, the mobile phone can be in communication connection with the plurality of electronic shelf labels 100 through the gateway device based on the Bluetooth protocol so as to determine the coordinate positions of shelves corresponding to the plurality of electronic shelf labels. Because the position of the commodity is bound to the corresponding shelf position of the electronic shelf label 100, the user can query the coordinate position of the commodity at the interface.
The gateway device 200 may determine the location of the commodity to be queried based on the information interaction method, and may generate a corresponding navigation line according to the location of the user and the location of the commodity to be queried, and the user may find the commodity to be queried according to the navigation line.
