Detailed Description

In order to make the technical solution of the present specification better understood by those skilled in the art, the technical solution of the present specification embodiment will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present specification, and it is apparent that the described embodiment is only a part of the embodiment of the present specification, but not all the embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are intended to be within the scope of the present disclosure.

The electronic price tag, also called electronic shelf tag, is an electronic display device, and can communicate through low-power consumption bluetooth protocol (Bluetooth Low Energy, BLE), wireless fidelity (Wireless Fidelity, wiFi) protocol, or private communication protocol based on 2.4GHz band and SUB 1GHz band, etc. to update and display the latest price and promotion information. The electronic price tag is generally used in places such as a large supermarket and a market, can improve sales efficiency and management efficiency, and has the advantages of high updating speed, accurate information, labor cost saving and the like. Electronic tags are typically powered by batteries, such as button cells, which are often capable of operating for 4-5 years or even longer after the battery is installed or replaced.

Because the number of the electronic price tags in places such as a large supermarket and a market is large, the distribution range is wide, the electronic price tags tend to move along with the commodity placement position, a cellular network is generally formed by a plurality of base stations to cover the areas of all the electronic price tags in the market and the supermarket, and networking and communication are performed on the basis of the plurality of base stations and the electronic price tags under the coverage areas of the base stations. In the related art, when the electronic price tag is networking, a heartbeat packet is generally sent to the base station through the electronic price tag, network access management is carried out on the electronic price tag based on the heartbeat packet sent by the electronic price tag, and because the heartbeat packet is sent at the electronic price tag timing, the electronic price tag is easy to cause higher power consumption in the network access process, so that the service life of the electronic price tag is reduced, and in the related art, the interval period of each heartbeat packet sent by the electronic price tag is longer, and the network access speed is slower.

In addition, in a large supermarket or a market, the number of commodities and goods is numerous, the number of corresponding electronic price tags is also very large, and often, management and operation are required to be performed on a large batch of electronic price tags at the same time, for example, when some large market has sales promotion activities, thousands, tens of thousands or hundreds of thousands of electronic price tags are required to be networked, and operations such as price changing and upgrading are required to be performed on a large batch of electronic price tags in a short time (for example, 20 minutes), but in the related art, the operations such as price changing and upgrading are difficult to be performed on a large batch of electronic price tags to be networked.

Therefore, it is necessary to provide a communication method of electronic price tags, in which an activation message is broadcast to a plurality of electronic price tags through a base station, so that when the electronic price tags receiving the activation message meet a preset network access condition, a network access request message carrying specified time information is sent to the base station, and after the network access request message is sent, a dormant state is maintained according to the specified time information so as to reduce power consumption in a network access process, and the base station can send a network access confirmation message carrying network access configuration information to the electronic price tag ending the dormant state according to the specified time information, so that the electronic price tag can access the network with the network access configuration information, and in this way, the power consumption of the electronic price tag can be reduced in the network access process of the electronic price tag.

Referring to fig. 1, fig. 1 is a schematic diagram of an electronic price tag communication system according to an embodiment of the present disclosure. The electronic price tag communication system may be a three-level network architecture including a server 110, a base station 120 and an electronic price tag 130, wherein the server 110 and the base station 120 may communicate through ethernet or 4G/5G, and the base station 120 and the electronic price tag 130 may communicate through 2.4G/Sub 1G.

The server may manage the base station and the electronic price tag through the base station. For example, the server may store upgrade package data of the base station and the electronic price tag, and the server may issue a base station OTA (Over the Air) upgrade instruction and the base station upgrade package data to the base station to instruct the base station to perform the base station OTA upgrade based on the base station upgrade package data. The server can issue a price tag OTA upgrade instruction and electronic price tag upgrade package data to the base station so as to instruct the base station to conduct price tag OTA upgrade on the electronic price tag based on the electronic price tag upgrade package data. For example, the server may store the price tag picture data, and the server may issue a price tag picture data refresh instruction and price tag picture data to the base station so that the electronic price tag may be instructed by the base station to refresh a price tag picture displayed by the electronic price tag based on the price tag picture data. The server may also monitor for anomalies in operation of the base station and the electronic price tag, for example. The server may also illustratively interface with supermarket/mall goods or cargo systems, etc.

The electronic price tag communication system can comprise a plurality of base stations, and the base stations can perform network access management, price tag awakening, price tag picture data refreshing, price tag OTA upgrading, indication reminding management and the like on the electronic price tag. The price tag awakening means that an electronic price tag in a dormant state is awakened to end the dormant state, so that price tag picture data refreshing, price tag OTA upgrading, indication reminding management or other operations can be performed on the electronic price tag.

Specifically, each base station may include a plurality of radio frequency modules, or may include a plurality of radio frequency chips, and each base station may correspond to a plurality of channels, where the plurality of channels corresponds to the plurality of radio frequency modules one to one. The plurality of channels corresponding to each base station may include at least one active channel, at least one common channel, and a plurality of data channels. Each base station may have a plurality of subnets, each of which corresponds to a plurality of data channels of the base station, or the subnets of each base station are determined according to the corresponding plurality of data channels. In order to suppress co-channel interference, respective frequency points of the at least one active channel are discontinuous, respective frequency points of the at least one common channel are discontinuous, and respective frequency points of the plurality of data channels are discontinuous.

The frequency points of the activation channels corresponding to the plurality of base stations are the same, the frequency points of the common channels corresponding to the plurality of base stations are the same, the frequency points of the data channels corresponding to the adjacent base stations are different, in other words, the plurality of base stations in the electronic price tag communication system share at least one activation channel and at least one common channel, and the plurality of data channels are used independently. Through the same active channel and the same common channel, when the electronic price tag moves to a cell corresponding to any base station in the electronic price tag communication system, the electronic price tag can quickly access the network through the same active channel and the common channel, so that the network access efficiency of the electronic price tag is improved; in addition, the network capacity of the base station can be improved by the independent and parallel networking of a plurality of corresponding subnets and a plurality of data channels, and the batch operation capability of the electronic price tag can be improved by the plurality of data channels, so that the management efficiency of the electronic price tag is improved.

Illustratively, the frequency points for each of the active channel, the common channel, and the data channel may be determined based on 40 channels of the industrial, scientific, medical (Industrial Scientific Medical Band, ISM) frequency band of bluetooth low energy technology (Bluetooth low energy, BLE) at 2.4 GHz. The BLE frequency band is divided into 40 channels, including 3 primary broadcast channels and 37 general purpose channels, and any one of the 37 general purpose channels may also be used as a standby broadcast channel, where the frequency points of the 3 primary broadcast channels are discontinuous.

As an example, at least one active channel and at least one common channel may be allocated based on 3 primary broadcast channels in a BLE band, and a plurality of data channels may be allocated based on 37 general purpose channels in the BLE band. As another example, allocation into at least one active channel and at least one common channel may be made based on at least one spare broadcast channel and 3 main broadcast channels preselected among 37 general use channels in the BLE band, and allocation into a plurality of data channels may be made based on general use channels other than the preselected at least one spare broadcast channel among the 37 general use channels in the BLE band.

For example, at least some of the 37 general purpose channels in the BLE frequency band may be used as preset data channels, and the preset data channels may be grouped to obtain a plurality of data channel groups, each data channel group may include a plurality of preset data channels, frequency points of the preset data channels in each data channel group are discontinuous, and the plurality of data channels corresponding to any base station may be a plurality of preset data channels in any preset data channel group.

For example, referring to fig. 2, any base station may include 6 radio frequency modules, and the base station may correspond to 1 active channel, 2 common channels, and 3 data channels. For example, the radio frequency modules 1, 2, 3, 4, 5, 6 may correspond to an active channel 1, a common channel 2, a data channel 1, a data channel 2, and a data channel 3, respectively. Wherein data channel 1, data channel 2 and data channel 3 may act as a subnet of the base station. As an example, the active channel 1 may be any one of 3 primary broadcast channels, and the common channel 1 and the common channel 2 may be the other 2 of the 3 primary broadcast channels. As an example, 3 data channels may be determined by: 24 of 37 general use channels in a BLE frequency band are selected as preset data channels, the 24 preset data channels are divided into 8 data channel groups, each data channel group comprises 3 discontinuous preset data channels of frequency points, and 3 preset data channels in any data channel group are selected as 3 data channels of a base station.

For example, referring to fig. 3, a plurality of base stations in the electronic price tag communication system may be a micro cellular network structure including a plurality of cells, a plurality of data channels corresponding to any base station may be a plurality of preset data channels in any one of the above 8 data channel groups, for example, the 8 data channel groups may be denoted by A, B, C, D, E, F, G, H, and data channel groups corresponding to adjacent base stations are different.

The active channel and the common channel of any base station may be configured by a server, for example.

Illustratively, the multiple data channels of any base station may be configured by: (1) After the base station is on line, receiving a base station detection starting instruction issued by a server, responding to the base station detection starting instruction, periodically broadcasting a detection message on a public channel, wherein the detection message carries the base station address of the base station, adding the base station address to a neighbor table after the adjacent base station receives the detection message, recording a base station signal strength indication value (Received Signal Strength Indication, RSSI) when the detection message is received, and adding the base station RSSI value to the neighbor table. (2) Meanwhile, the base station can also receive the detection message broadcast by the adjacent base station on the public channel, and the address of the adjacent base station and the corresponding RSSI value of the adjacent base station are added to the neighbor table of the base station. (3) The base station can stop sending the detection message and stop receiving the detection message broadcasted by the adjacent base station after receiving the detection instruction of stopping the base station issued by the server. (4) The base station can upload the neighbor list of the base station to the server after receiving the instruction of reading the neighbor list of the base station issued by the server. (5) The server may allocate a data channel group according to the address of the neighboring base station and the RSSI value of the base station in the neighbor table uploaded by each base station, so that a plurality of base stations in the electronic price tag communication system form a micro-cellular network structure as shown in fig. 3.

The electronic price tag communication system may include a plurality of electronic price tags. Any one of the plurality of base stations has a cell corresponding to the base station, and when any electronic price tag is in the cell of the base station, the electronic price tag can access to the network and communicate through the base station corresponding to the cell. For example, the cell in which the electronic price tag is located may be determined according to the signal quality between the electronic price tag and any base station, or the base station that is networked with the electronic price tag may be directly determined.

In particular, the electronic price tag may be in any of a variety of modes of operation. The plurality of working modes can comprise at least one of a shutdown mode, an offline mode, a network access mode and an online mode. For example, the electronic price tag can activate the shutdown mode to reduce the power attenuation caused by long-term placement in the warehouse before production is completed and put into use, or can be readjusted to the shutdown mode when the electronic price tag is put back into the warehouse after a period of use or does not receive downlink messages such as heartbeat messages, wake-up messages and the like of the base station due to specific reasons, so as to reduce the power consumption of the electronic price tag and prolong the service life of the electronic price tag. When in the offline mode, the electronic price tag can perform network access judgment to judge whether the electronic price tag can access the network. When in the network access mode, the electronic price tag can execute a network access interaction flow with the base station so as to acquire network access configuration information for network access and access the network by the network access configuration information. When in the online mode, the price tag picture data can be refreshed and displayed, the price tag OTA is upgraded, the indication reminding and the like. For example, the electronic price tag may be configured with an indicator Light such as a Light-emitting diode (LED), and the indication alert may refer to the LED flashing. For example, the electronic price tag may be configured with a sound emitting component such as a buzzer, and the indication alert may also mean that the buzzer sounds.

Specifically, the electronic price tag in the shutdown mode, the offline mode or the online mode can periodically open the receiving window, so as to receive the downlink message issued by at least one base station through the receiving window. The electronic price tag in the off mode, the off-line mode or the on-line mode may enter a sleep state when the receiving window is not opened. The electronic price tag in the network access mode can also enter a dormant state when the network access interaction flow is executed but the downlink message issued by the base station is not received. The power consumption level corresponding to the sleep state is lower than the power consumption level corresponding to the sleep state when the network access mode is in the shutdown mode, the offline mode or the online mode. Wherein, the higher the power consumption level, the higher the power consumption of the electronic price tag.

For example, the power consumption level corresponding to the sleep state being maintained in the shutdown mode, the offline mode, or the online mode may be LP2, and the power consumption level corresponding to the sleep state being maintained in the network access mode may be LP0, where the power consumption of LP0 is greater than the power consumption of LP 2.

For example, an electronic price tag in a shutdown mode may periodically open a receiving window at intervals of a first sleep duration, and an electronic price tag in an online mode may periodically open a receiving window at intervals of a second sleep duration. As one example, an average current of an electronic price tag in a shutdown mode for one sleep period is 1.52 μa, including a 1.2 μa bottom current that remains dormant at the LP2 power consumption level, and a receive window average current of 0.32 μa, with a power consumption of about 13.3mA for 1 year.

Illustratively, the electronic price tag in the online mode and the electronic price tag in the offline mode are the same in the interval duration of opening the receiving window. The interval duration of opening the receiving window when in the on-line mode is longer than the interval duration of opening the receiving window when in the off-line mode.

Illustratively, the electronic price tag may display price tag picture data through an ink screen. The ink screen, also called electronic paper display screen, can adopt electrophoretic display technology (Electrophoresis Display, EPD) as a display panel, and has the characteristic of ultra-low power consumption in the later period.

Referring to fig. 4, fig. 4 is a schematic flow chart of the electronic price tag communication method provided in the present embodiment, and the present embodiment provides the method operation steps as the flow chart, but may include more or less operation steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one implementation of a plurality of step execution orders and does not represent a unique execution order. In actual system or server product execution, the methods illustrated in the embodiments may be performed sequentially or in parallel (e.g., in parallel processors or in the context of multi-threaded processing). The electronic price tag communication method can be applied to any one of a plurality of base stations in an electronic price tag communication system, and particularly as shown in fig. 4, the electronic price tag communication method can comprise the following steps.

Step S410: broadcasting an activation message to a plurality of electronic price tags within a specified activation time period; the method comprises the steps of designating an activation time period to be longer than a first dormancy time period; the activation message is used for indicating that the electronic price tag in the shutdown mode is adjusted from the shutdown mode to the offline mode; the electronic price tag in the offline mode can be adjusted to the online mode from the offline mode when the preset online condition is met.

In some cases, among a plurality of electronic tags in the electronic tag communication system, a part of electronic tags can be in a shutdown mode in a plurality of working modes, the electronic tags in the shutdown mode can periodically open a narrower receiving window at intervals of a first sleep time length, so that whether base stations exist around or whether base stations send activation messages or not is detected through the receiving window, if the base stations send the activation messages, the network access is started, and if the base stations do not send the activation messages, the shutdown mode with low power consumption is kept continuously.

In this embodiment, the base station may broadcast the activation message to a plurality of electronic price tags within a specified activation time period. The electronic price tag in the shutdown mode in the plurality of electronic price tags can be adjusted from the shutdown mode to an offline mode capable of performing network access determination under the condition that an activation message is received through a receiving window. Specifically, the electronic price tag may store a preset network access condition for performing network access determination, and when the preset network access condition is satisfied, the electronic price tag in the offline mode may be adjusted from the offline mode to the network access mode for executing the network access interaction procedure.

For example, referring to fig. 5, the first sleep duration corresponding to the shutdown mode may be 600 seconds, and the receiving window may be 5 ms, that is, the electronic price tag in the shutdown mode may open a receiving window of 5 ms every 600 seconds. The designated activation duration of the base station may be 610 seconds, or the duration of one activation message broadcast by the base station may be 610 seconds. Because the appointed activation time length 610 seconds is longer than the first dormancy time length 600 seconds, when the base station broadcasts an activation message once, the electronic price tag in the shutdown mode can receive the activation message through the receiving window, responds to the activation message, is adjusted to an offline mode capable of performing network access judgment based on a preset network access condition by the shutdown mode, and is adjusted to a network access mode for executing a network access interaction flow by the offline mode under the condition that the preset network access condition is met.

Illustratively, the base station may broadcast the activation message in an activation period. For example, with continued reference to fig. 5, the ACTIVATION period may be 3610 seconds, i.e., the activation_ind ACTIVATION message is broadcast once every 3610 seconds, and the designated ACTIVATION period for broadcasting the activation_ind ACTIVATION message is 610 seconds. The activation period may be set by the server, for example.

Step S420: receiving a network access request message sent by an electronic price tag in a network access mode; the network access request message carries appointed time information; the electronic price tag in the network access mode can maintain the sleep state based on the specified time information.

In some cases, after the electronic price tag in the offline mode is adjusted from the offline mode to the online mode, the online interaction process with the base station may be performed, that is: the electronic price tag sends a network access request message to the base station, the base station determines network access configuration information after receiving the network access request message, and feeds back a network access confirmation message to the electronic price tag, and the electronic price tag receives the network access confirmation message and accesses the network by the network access configuration information carried in the network access confirmation message. However, after receiving the network access request message sent by the electronic price tag, the base station needs time to determine network access configuration information, often cannot immediately feed back the network access confirmation message, the electronic price tag consumes longer time in the process of waiting for receiving the network access confirmation message fed back by the base station with high power consumption, so that the power consumption of the electronic price tag is higher, and in order to reduce the power consumption of the electronic price tag in the network access process, the electronic price tag can be kept in a dormant state after sending the network access request message and before receiving the network access confirmation message.

In this embodiment, the electronic price tag that is adjusted to the network access mode from the offline mode may determine the specified time information, and after sending the network access request message to the base station, enter and maintain the sleep state according to the specified time information. The base station can receive the network access request message carrying the appointed time information sent by the electronic price tag in the network access mode. Specifically, the specified time information may refer to a specified end time of the sleep state of the electronic price tag in the network access mode, that is, after the specified end time, the electronic price tag in the network access mode may receive the network access confirmation message, or the specified time information may refer to a specified receiving time of the electronic price tag in the network access mode to the network access confirmation message. Specifically, the specified time information may also refer to a time offset, where the time offset may represent an offset between a current time and a specified end time, that is, an offset between the current time and a specified receiving time, in the process of maintaining the sleep state of the electronic price tag in the network access mode. When the time offset is zero, the electronic price tag in the network access mode can end the dormant state and prepare to receive the network access confirmation message issued by the base station.

For example, with continued reference to fig. 5, in fig. 5, TX represents transmission (transport), RX represents reception (receive), an electronic price tag adjusted from offline mode to network access mode may send a join_req network access request message with a time offset to a base station, and may enter and maintain a sleep state based on the time offset after sending the join_req network access request message until a specified end time or a specified reception time.

Step S430: based on the appointed time information, sending a network access confirmation message carrying network access configuration information to the electronic price sign in the network access mode, so that the electronic price sign in the network access mode is adjusted to an online mode from the network access mode in response to the network access confirmation message; the electronic price tag in the online mode can be accessed to the internet through the access configuration information.

In this embodiment, after receiving a network access request message sent by an electronic price tag in a network access mode, a base station may determine corresponding network access configuration information for the electronic price tag, and send a network access confirmation message carrying the network access configuration information to the electronic price tag based on specified time information carried in the network access request message, so that the electronic price tag may be adjusted from the network access mode to an online mode capable of accessing the network with the network access configuration information in response to the network access confirmation message.

For example, referring to fig. 5, the join_req network access request message may carry a time offset time_offset, and the base station may send a join_resp network access confirmation message to the electronic price tag in the network access mode that ends the sleep state according to the time offset time_offset, so that the electronic price tag in the network access mode is adjusted from the network access mode to an online mode capable of accessing the network with the network access configuration information carried in the network access confirmation message in response to the network access confirmation message.

In the above embodiment, the electronic price tag in the shutdown mode can determine whether to access the network only through the periodically opened narrower receiving window, without sending a message to the base station, and in the process of indicating the electronic price tag to access the network by the base station, the electronic price tag can complete the network access only by sending fewer messages, so that the power consumption in the network access process can be reduced to a certain extent, and meanwhile, in the network access interaction process with the base station after determining to access the network, the electronic price tag can keep the dormant state in the time period between sending the network access request message to the base station and receiving the network access confirmation message issued by the base station, so that the power consumption of the electronic price tag in the network access process can be further reduced.

In some embodiments, sending the network entry confirmation message carrying the network entry configuration information to the electronic price sign in the network entry mode may include: if the network access confirmation query message sent by the electronic price tag in the network access mode after the sleep state is ended is received, the network access confirmation message carrying network access configuration information is sent to the electronic price tag in the network access mode.

In some cases, in the network access interaction flow between the electronic price tag in the network access mode and the base station, a network access confirmation query message can be sent to the base station according to the specified time information, or the network access confirmation query message can be sent to the base station after the sleep state is ended, so that the base station is instructed to send the network access confirmation message to the electronic price tag in the sleep state is ended.

In this embodiment, after determining the network access configuration information of the electronic price tag in the network access mode, the base station may prepare a network access confirmation query message of the electronic price tag in advance according to the specified time information, and if the network access confirmation query message sent by the electronic price tag is received, it may determine that the electronic price tag has ended the sleep state, and send the network access confirmation message carrying the network access configuration information to the electronic price tag. The base station may send the network entry confirmation message to the electronic price tag, and then upload the network entry configuration information to the server, so that the server may determine a mapping relationship between the electronic price tag and the base station according to the network entry configuration information of the electronic price tag, and further, the server may manage the electronic price tag based on the mapping relationship.

For example, with continued reference to fig. 5, the specified time information may be a time offset time_ofest, after the electronic price tag in the network access mode ends the sleep state according to the time offset time_offset, the electronic price tag may send a get_join_resp network access confirmation query message to the base station, meanwhile, the base station may prepare the get_join_resp network access confirmation query message in advance according to the time offset time_offset, and if the base station receives the get_join_resp network access confirmation query message, send the join_resp network access confirmation message to the electronic price tag, so that the electronic price tag can access the network with the network access configuration information carried by the join_resp network access confirmation message.

In the above embodiment, the network access confirmation message is issued to the electronic price tag only when the network access confirmation query message is received, so that the issued network access confirmation message can be received by the electronic price tag in the network access mode in the sleep state, thereby improving the network access success rate under the condition of reducing the network access power consumption of the electronic price tag, and simultaneously, the electronic price tag in the network access mode can be timely accessed after the sleep state is ended, and improving the network access speed.

In some embodiments, the electronic price tag in online mode can open the receive window for a second sleep period. The second dormancy duration is smaller than the first dormancy duration.

In some cases, the electronic price tag in the online mode can determine the duration of the online mode through a heartbeat message broadcast by the base station, or can maintain the online mode based on the heartbeat message, so as to ensure the normal use of the electronic price tag.

In this embodiment, the communication method of the electronic price tag may further include: and broadcasting a heartbeat message to the electronic price tag in the online mode according to the heartbeat period to indicate that the electronic price tag in the online mode maintains the online mode. Wherein the heartbeat cycle is greater than the second sleep duration. Specifically, when the base station broadcasts a heartbeat message to the electronic price tag in the online mode according to the heartbeat period, the heartbeat time length in each heartbeat period is longer than the second dormancy time length. In the process of maintaining the online mode based on the heartbeat message, if the heartbeat message broadcast by the base station according to the heartbeat period is not received within the appointed duration, the electronic price tag in the online mode can be adjusted to an offline mode from the online mode. The designated duration is greater than the heartbeat period, and the designated duration can be a duration spanned by a plurality of receiving windows continuously designated. That is, if the electronic price tag in the online mode continuously designates a number of receiving windows to not receive the heartbeat message, the online mode may be adjusted to the offline mode to perform the network access determination again.

For example, with continued reference to fig. 5, the second sleep period corresponding to the online mode may be 60 seconds, and the receiving window may be 5 ms, that is, the electronic price tag in the online mode may open a receiving window of 5 ms at 60 seconds intervals. The heartbeat period may be 10 minutes, i.e. the base station may broadcast a heartbeat message every 600 seconds, the heartbeat duration in one heartbeat period may be 61 seconds, or the duration of the base station broadcasting a heartbeat message once is 61 seconds. Because the heartbeat time length 61 seconds is longer than the second dormancy time length 60 seconds, when the heartbeat message is broadcast once, the electronic price tag in the online mode in the cell corresponding to the base station can receive the heartbeat message through the receiving window. As an example, the specified duration may be a duration spanned by 60 consecutive receiving windows, and if no heartbeat message is received within the specified duration, the electronic price tag in the online mode is adjusted to the offline mode from the online mode, or if no heartbeat message is received by 60 consecutive receiving windows, the electronic price tag in the online mode is adjusted to the offline mode from the online mode.

As one example, an electronic price tag in online mode may determine whether to adjust from online mode to offline mode through an offline counter. For example, based on the periodically opened receiving window, if the heartbeat message is received in the receiving window, the offline counter is reset to 0, and if the heartbeat message is not received in the receiving window, the offline counter counts until the count of the offline counter reaches 60. When the count of the offline counter reaches 60, the online mode is adjusted to the offline mode to make a network access determination again.

In the above embodiment, the base station broadcasts the heartbeat message according to the heartbeat period, so that when the electronic price tag in the online mode does not receive the heartbeat message of the base station for a long time, for example, when the communication between the electronic price tag and the base station fails due to link interference or when the electronic price tag moves out of a cell of the base station, the electronic price tag exits the online mode with higher power consumption in time, thus, the network access power consumption of the electronic price tag can be reduced, and the service life of the electronic price tag is prolonged.

In some embodiments, any base station may communicate with a plurality of electronic tags through its corresponding plurality of channels.

In some cases, for any base station, in order to improve networking and communication efficiency, in the networking and communication process of the electronic price tag, different types of messages can be broadcast or transmitted through corresponding types of channels.

In this embodiment, the activation message may be broadcast on at least one activation channel corresponding to the base station. Specifically, since the active channel may be shared or shared by multiple base stations in the electronic price tag communication system, before broadcasting on the active channel, the base station may initiate an active channel occupation request to the server, and after receiving the designated active channel fed back by the server, broadcast an active message to multiple electronic price tags on the designated active channel in the corresponding at least one active channel. As an example, the base station may also broadcast the activation message over the designated activation channel for the occupied period after receiving the designated activation channel and the occupied period of the designated activation channel fed back by the server. As an example, the plurality of channels corresponding to the base station may include an active channel, and the base station may further broadcast the active message through the active channel during the occupied period after receiving the occupied period fed back by the server.

Specifically, the activation message may carry common channel frequency point information, where the common channel frequency point information indicates a frequency point of at least one common channel corresponding to the base station. The electronic price tag in the network access mode may determine at least one common channel for transmitting the network access request message based on the common channel frequency point information.

In this embodiment, the network access request message may be transmitted on at least one common channel corresponding to the base station. Specifically, the base station may receive the network access request message on any one of the corresponding at least one common channel, and store information carried by the network access request message. The network access request message may carry specified time information and network access confirmation random channel information indicating a network access confirmation random channel.

The network access confirmation random channel is determined when the electronic price tag in the network access mode sends the network access request message, and is used for transmitting the network access confirmation inquiry message and the network access confirmation message. The network access acknowledgement random channel may be any one of 37 general purpose channels in the BLE frequency band, may be any one of a preset data channel in any one of a plurality of data channel groups, or may be any one of a plurality of data channels corresponding to the base station.

For example, before sending the network access request message to the base station through at least one common channel, the electronic price tag in the network access mode may determine an idle state of any one of 37 general purpose channels in the BLE frequency band and select any one of the 37 general purpose channels as a network access acknowledgement random channel, may determine an idle state of a preset data channel in any one of a plurality of data channel groups and select any one of the idle state as a network access acknowledgement random channel, or may determine an idle state of any one of a plurality of data channels and select any one of the idle state data channel as a network access acknowledgement random channel.

In this embodiment, the network access confirmation query message and the network access confirmation message may be transmitted on a random network access confirmation channel. Specifically, the base station may determine a network access confirmation random channel according to the network access confirmation random channel information in the network access request message, and receive the network access confirmation query message sent by the electronic price tag in the network access mode on the network access confirmation random channel, and may send the network access confirmation message to the electronic price tag in the network access mode on the network access confirmation random channel after receiving the network access confirmation query message.

In this embodiment, the heartbeat message may be broadcast on a plurality of data channels of the base station. Specifically, the base station may begin broadcasting the heartbeat message on each of the corresponding plurality of data channels after the corresponding plurality of data channels are configured.

For example, referring to fig. 2 and 5, the base station may broadcast an activity_ind ACTIVATION message to a plurality of electronic tags on an ACTIVATION channel 1, and receive a join_req network access request message sent by the electronic tags in a network access mode on a common channel 1 or a common channel 2; the network access request message may carry a time offset and network access confirmation random channel information random_channel, the base station may determine the network access confirmation random channel from the data channel 1, the data channel 2 and the data channel 3 according to the network access confirmation random channel information ramdom_channel, and the base station may prepare to receive the get_join_resp network access confirmation query message on the network access confirmation random channel according to the time offset, and then send the join_resp network access confirmation message on the network access confirmation random channel after receiving the get_join_resp network access confirmation query message. The base station may broadcast heartbeat messages on data channel 1, data channel 2, and data channel 3, respectively, when configuration of data channel 1, data channel 2, and data channel 3 is complete.

In the above embodiment, when the activation message is broadcast on the shared activation channel and the network access request message is transmitted on the shared public channel, the electronic price tag can be quickly accessed to the network through the activation channel and the public channel when moving to the cell of any base station in the electronic price tag communication system, so that the network access efficiency of the electronic price tag is improved.

In some embodiments, for any base station, any subnet of the base station has a corresponding short address space having a plurality of communication short addresses, wherein the plurality of communication short addresses includes at least one free short address. Wherein the free short address in the short address space of any one of the subnets represents a communication short address which has not been allocated to the electronic price tag, and the communication short address except the free short address in the short address space of any one of the subnets is a communication short address which has been allocated to the electronic price tag.

In this embodiment, referring to fig. 6, the network access configuration information corresponding to the electronic price tag in the network access mode by any base station may be determined in the following manner.

Step S610: determining the residual capacity of a base station of the base station and the corresponding request signal quality when receiving a network access request message; wherein the base station remaining capacity represents the number of free short addresses in a plurality of short address spaces of the base station.

In some cases, due to the location of the electronic price tag, there may be a plurality of base stations receiving the network access request message of one electronic price tag at the same time, so any base station receiving the network access request message may initiate a base station network access request to the server, so that one base station may be preferentially selected as a parent base station of the electronic price tag through the server.

In this embodiment, after receiving the network access request packet, the base station may record the quality of the request signal corresponding to the network access request packet when receiving the network access request packet, that is, the RSSI value corresponding to the network access request packet when receiving the network access request packet, determine the number of idle short addresses based on the short address spaces of all subnets of the base station, and use the number of idle short addresses as the remaining capacity of the base station.

Step S620: and uploading the residual capacity of the base station and the quality of the request signal to a server.

In this embodiment, the base station may upload the base station remaining capacity and the request signal quality to the server, so that the server may determine whether to use the base station as a parent base station of the electronic price tag based on the base station remaining capacity and the request signal quality of the base station. Specifically, the server may further receive the remaining capacity and the request signal quality of the neighboring base station for the electronic price tag uploaded by any neighboring base station, and the server may determine the parent base station of the electronic price tag according to the remaining capacity and the request signal quality of the base station of the neighboring base station, and the remaining capacity and the request signal quality of the neighboring base station.

Step S630: if a parent base station confirmation instruction fed back by the server based on the base station residual capacity and the request signal quality is received, determining network access configuration information corresponding to the electronic price tag in the network access mode.

In some cases, the server may issue a parent base station confirmation instruction to the parent base station after determining the parent base station of the electronic price tag.

In this embodiment, if the base station receives the parent station confirmation instruction fed back by the server, the base station may determine the network access configuration information corresponding to the electronic price tag in response to the parent station confirmation instruction.

In the above embodiment, after receiving the network access request message sent by the electronic price tag, the base station determines the base station residual capacity of the base station, records the corresponding request signal quality when receiving the network access request message, and uploads the base station residual capacity and the request signal quality to the server, so that the server can preferentially select a suitable parent base station according to the base station residual capacity and the request signal quality of the base station and the adjacent base station, and thus, the network access stability of the electronic price tag can be improved. In addition, through a plurality of subnets of the base station and the corresponding short address space, the network access capacity of the base station to the electronic price tags can be improved, meanwhile, network access configuration information can be determined for a plurality of electronic price tags through a plurality of subnets in parallel, and the networking efficiency of the electronic price tags is improved.

In some embodiments, the plurality of subnets have respective subnet encodings. Wherein the subnet code is used to uniquely identify the corresponding subnet.

In this embodiment, referring to fig. 7, determining the network access configuration information corresponding to the electronic price tag in the network access mode may include the following steps.

Step S710: any one of a plurality of subnets is selected.

Specifically, the base station may select any one subnet from the multiple subnets of the base station as the subnet corresponding to the electronic price tag in the network access mode in response to the parent base station confirmation instruction issued by the server. For example, the sub-network corresponding to the electronic price tag may be selected according to the number of free short addresses in the short address space of each sub-network. For example, a subnet corresponding to a short address space having the largest free short address may be used as a subnet corresponding to the electronic price tag. For example, the plurality of subnets may have respective selection orders, and a subnet in which a free short address exists in the short address space may be regarded as a subnet corresponding to the electronic price tag according to the selection orders.

Step S720: and taking any free short address in the short address space of the selected subnet as a price tag address.

Specifically, the plurality of communication short addresses in each short address space have a corresponding address sequence, and the base station may sequentially select one free short address as a price tag address corresponding to the electronic price tag according to the address sequence of the plurality of communication short addresses in the selected short address space of the subnet.

Step S730: and determining networking configuration information corresponding to the electronic price tag in the networking mode based on the price tag address and the subnet code of the selected subnet.

Specifically, the base station may determine the network access configuration information corresponding to the electronic price tag in the network access mode based on the price tag address and the subnet code of the selected subnet. The network access configuration information corresponding to the electronic price tag comprises a price tag address and a subnet code.

In the above embodiment, after the base station is determined as the parent base station of the electronic price tag, by selecting the subnet and the idle short address in the short address space corresponding to the subnet, the network access configuration information including at least the subnet code and the price tag address can be determined, so that the electronic price tag in the network access mode can access the network based on the network access configuration information, and the base station can wake up the electronic price tag, and further can perform operations such as price tag picture data refreshing, price tag OTA upgrading, and indication reminding management on the electronic price tag in the online mode.

In some embodiments, any base station has a respective base station code, wherein the base station code is used to uniquely identify the corresponding base station. The determining network access configuration information corresponding to the electronic price tag in the network access mode may further include: and determining network access configuration information corresponding to the electronic price tag in the network access mode based on the base station code. The network access configuration information corresponding to the electronic price tag can include a base station code of the base station to which the electronic price tag belongs.

In some embodiments, determining the network access configuration information corresponding to the electronic price tag in the network access mode may further include: and determining network access configuration information corresponding to the electronic price tag in the network access mode based on the data channel corresponding to the selected subnet. The network access configuration information corresponding to the electronic price tag may include a data channel of the corresponding subnet. Therefore, after the electronic price tag is accessed to the network, the heartbeat message issued by the base station can be received through the corresponding data channel to maintain the network access state, or the wake-up message issued by the base station is received to realize price tag picture data refreshing, price tag OTA upgrading, indication reminding and the like.

In some embodiments, the method of communicating an electronic price tag may further include: and sending a wake-up message to the electronic price tag in the online mode to indicate that the electronic price tag in the online mode can respond to the wake-up message, so as to realize price tag picture data refreshing, price tag OTA upgrading or indication reminding.

In some cases, the electronic price tag in the online mode can periodically open a receiving window to receive a wake-up message issued by the base station to which the electronic price tag belongs, and wake up from a sleep state in response to the wake-up message.

In this embodiment, the wake-up message may carry any one of a price tag OTA upgrade command, a price tag picture data refresh command, or an instruction alert command. The price tag OTA upgrade command, the price tag picture data refresh command and the indication reminding command may be determined according to a price tag OTA upgrade command, a price tag picture data refresh command and an indication reminding command issued by the server, respectively, and the price tag OTA upgrade command, the price tag picture data refresh command and the indication reminding command are used for indicating that an electronic price tag in an online mode enters a price tag OTA upgrade state, a price tag picture data refresh state and an indication reminding state, respectively.

Specifically, the wake-up message may carry a wake-up bitmap, where the wake-up bitmap is determined based on a short address space of any subnet of the base station, and the wake-up bitmap includes a wake-up address for indicating any electronic price tag to wake up, so that after the electronic price tag in online mode receives the wake-up message, whether a wake-up address corresponding to the price tag address in the network access configuration information exists in the wake-up bitmap can be determined, and if so, the wake-up message can be responded.

Specifically, after issuing a wake-up message carrying a price tag OTA upgrade command to an electronic price tag in an online mode, the base station may issue a data message carrying electronic price tag upgrade package data to the electronic price tag in the online mode, so that the electronic price tag can perform electronic price tag OTA upgrade based on the electronic price tag upgrade package data. Therefore, the firmware of the electronic price tag can be repaired, updated or upgraded, and the stability of the electronic price tag is improved.

Specifically, after issuing a wake-up message carrying a price tag picture data refreshing command to an electronic price tag in an online mode, the base station issues a data message carrying price tag picture data to the electronic price tag in the online mode, so that the electronic price tag can be refreshed and displayed based on the price tag picture data, and the price information of the corresponding commodity is modified and displayed.

Specifically, the indication reminding command can carry the appointed reminding time length information, and the electronic price tag in the online mode can keep the indication reminding state according to the appointed reminding time length information. For example, the electronic price tag in the on-line mode indicating the reminding state may perform LED flashing, buzzer sounding, or the like indicating the reminding. Therefore, the position of the electronic price tag can be quickly determined and searched, and the electronic price tag can be conveniently managed.

Specifically, the wake-up message and the data message may be transmitted through corresponding data channels.

Referring to fig. 8, fig. 8 is a schematic flow chart of an electronic price tag communication method provided in the present embodiment, where the electronic price tag communication method may be applied to any one of a plurality of electronic price tags in an electronic price tag communication system, and specifically as shown in fig. 8, the electronic price tag communication method may include the following steps.

Step S810: and under the condition of being in a shutdown mode, if the activation message broadcast by any base station is received in the receiving window, the shutdown mode is adjusted to be an offline mode capable of judging based on the preset network access condition.

In some cases, multiple base stations of the electronic price tag communication system may broadcast activation messages to multiple electronic price tags within a specified activation time period, respectively. When the electronic price tag is in a shutdown mode, a narrower receiving window can be periodically opened, so that whether base stations exist around or whether base stations issue an activation message is detected through the receiving window, if the base stations issue the activation message, network access is started, and if the base stations do not issue the activation message, the shutdown mode with low power consumption is continuously maintained.

In this embodiment, when the electronic price tag is in the power-off mode, the electronic price tag may periodically open the receiving window at intervals of a first sleep duration, where the activation time period is specified to be longer than the first sleep duration. If the electronic price tag in the shutdown mode receives the activation message broadcast by any base station in the receiving window, the shutdown mode can be adjusted to the offline mode so as to perform network access judgment in the offline mode.

Step S820: and under the condition of being in an offline mode, if the preset network access condition is met, adjusting the network access mode from the offline mode.

In this embodiment, the electronic price tag may store a preset network access condition for performing the network access determination, and when the electronic price tag is in the offline mode, if the preset network access condition is satisfied, the electronic price tag may be adjusted from the offline mode to the network access mode for executing the network access interaction procedure.

Step S830: and under the condition of being in the network access mode, sending a network access request message carrying the specified time information to the base station, and keeping the dormant state based on the specified time information.

In this embodiment, when the electronic price tag is adjusted from the network access mode to the network access mode, the specified time information may be determined, and the network access request message carrying the specified time information may be sent to the base station, so that the base station may issue the network access confirmation message based on the specified time information. Meanwhile, the electronic price tag can enter and keep a dormant state according to the appointed time information after sending a network access request message to the base station.

Specifically, the specified time information may refer to a specified end time when the electronic price tag is in the network access mode and keeps in a dormant state, or may refer to a specified receiving time of the electronic price tag for the network access confirmation message issued by the base station.

Specifically, the specified time information may also refer to a time offset, where the time offset may represent an offset between a current time and a specified end time, that is, an offset between the current time and a specified receiving time, in the process of maintaining the sleep state of the electronic price tag.

Step S840: receiving a network access confirmation message sent by a base station based on the appointed time information; the network access confirmation message carries network access configuration information.

In some cases, after receiving the network access request message, the base station may determine corresponding network access configuration information according to the electronic price tag, and issue a network access confirmation message carrying the network access configuration information based on the specified time information carried in the network access request message.

In this embodiment, after the electronic price tag ends the sleep state based on the specified time information, the electronic price tag may receive an access confirmation message sent by the base station based on the specified time information. Specifically, the electronic price tag may end the sleep state at a specified end time or a specified receiving time, and then receive the network access confirmation message sent by the base station, or may end the sleep state when the time offset is zero, and then receive the network access confirmation message sent by the base station.

Step S850: and responding to the network access confirmation message, and adjusting the network access mode to an online mode capable of accessing the network by using the network access configuration information.

In this embodiment, after receiving the network access confirmation message issued by the base station, the electronic price tag may be adjusted from the network access mode to an online mode capable of accessing the network with the network access configuration information in response to the network access confirmation message.

In the above embodiment, whether network access is needed can be determined through the narrower receiving window which is periodically opened by the electronic price tag, and a message is not required to be sent to the base station, and in the process that the base station indicates the electronic price tag to access the network, the electronic price tag can complete network access only by sending fewer messages, so that the power consumption in the network access process can be reduced to a certain extent, and meanwhile, in the network access interaction process with the base station after the network access is determined, the electronic price tag can keep a dormant state in the time period between sending the network access request message to the base station and receiving the network access confirmation message issued by the base station, so that the power consumption of the electronic price tag in the network access process can be further reduced.

In some embodiments, the network access confirmation message sent by the receiving base station based on the specified time information may include: based on the appointed time information, sending a network access confirmation query message to the base station; receiving a network access confirmation message; the network access confirmation message is sent after the base station receives the network access confirmation query message based on the appointed time information.

In some cases, the base station may determine the corresponding network access configuration information for the electronic price tag after receiving the network access request message, and may prepare a network access confirmation query message for the electronic price tag in advance according to the specified time information, and if the network access confirmation query message sent by the electronic price tag is received, may determine that the electronic price tag has ended the sleep state, and send the network access confirmation message carrying the network access configuration information to the electronic price tag.

In this embodiment, after the sleep state is finished based on the specified time information, the electronic price tag may send a network access confirmation query message to the base station, and receive a network access confirmation message carrying network access configuration information fed back by the base station.

In the above embodiment, the network access confirmation query message is sent to the base station after the sleep state is finished, so that the base station sends the network access confirmation message after receiving the network access confirmation query message, and thus, the receiving rate of the electronic price tag to the network access confirmation message can be improved, the network access success rate can be improved under the condition of reducing the network access power consumption of the electronic price tag, and meanwhile, the electronic price tag can access the network in time after the sleep state is finished, and the network access speed is improved.

In some embodiments, the receiving window can be opened at intervals of a second sleep period when the electronic price tag is in an online mode. The second dormancy duration is smaller than the first dormancy duration.

In this embodiment, referring to fig. 9, the electronic price tag communication method may further include the following steps.

Step S910: under the condition of being in an online mode, receiving a heartbeat message broadcasted by any base station according to a heartbeat period based on a receiving window opened at intervals of a second dormancy duration; wherein the heartbeat cycle is greater than the second sleep duration.

In some cases, the base station may broadcast a heartbeat message to the electronic price tag in online mode in a heartbeat cycle to indicate that the electronic price tag in online mode remains in online mode.

In this embodiment, when the electronic price tag is in the online mode, the receiving window may be periodically opened at intervals of the second sleep duration, and the heartbeat message broadcasted by the base station according to the heartbeat cycle may be received through the receiving window. Specifically, when the electronic price tag is in the online mode, the affiliated base station can be determined according to the network access configuration information, and the heartbeat message issued by the affiliated base station is received through the receiving window.

Step S920: and maintaining an online mode according to the heartbeat message.

In some cases, the electronic price tag may maintain an online mode based on whether a heartbeat message is received within a specified period of time.

In this embodiment, when the electronic price tag is in the online mode, if the heartbeat message broadcast by the base station according to the heartbeat cycle is not received within the specified duration, the online mode may be adjusted to the offline mode. The designated duration is greater than the heartbeat period, and the designated duration can be a duration spanned by a plurality of receiving windows continuously designated. That is, when the electronic price tag is in the online mode, if the heartbeat messages are not received by the continuously specified number of receiving windows, the online mode can be adjusted to the offline mode so as to carry out network access judgment again.

In the above embodiment, the heartbeat message periodically broadcast by the base station is received by periodically opening the receiving window, and when the heartbeat message is not received within the specified duration, for example, when the electronic price tag moves out of the cell of the base station to which the electronic price tag belongs or when the link interference occurs to cause the communication failure between the electronic price tag and the base station to which the electronic price tag belongs, the online mode with higher power consumption is timely exited, so that the network access power consumption of the electronic price tag can be reduced, and the service life of the electronic price tag is prolonged.

In some embodiments, when the electronic price tag is in the online mode, if the continuous specified number of receiving windows does not receive any message, the online mode may be adjusted to the offline mode, so as to make a network access determination again. Wherein, the arbitrary message can activate message, heartbeat message, wake-up message or data message.

As one example, when the electronic price tag is in online mode, it may be determined by an offline counter whether to adjust from online mode to offline mode. For example, based on the periodically opened receiving window, if any message is received in the receiving window, the offline counter is reset to 0, and if any message is not received in the receiving window, the offline counter is used for counting until the count of the offline counter reaches 60. When the count of the offline counter reaches 60, the online mode is adjusted to the offline mode to make a network access determination again.

In some embodiments, the electronic price tag communication method may further include: and under the condition of being in the offline mode, if the preset network access condition is not met, the offline mode is adjusted to be in the shutdown mode.

In this embodiment, when the electronic price tag is in the offline mode, the network access determination may be performed based on a preset network access condition, and the offline mode may be adjusted to the online mode or the shutdown mode according to the determination result. Specifically, the preset network access condition may include any one of the following conditions: (1) The network access times in the appointed time period do not exceed the threshold value of the network access times; (2) If any message of the original base station is received in the receiving window and the signal quality of the any message is within the signal quality threshold value range under the condition of being in the offline mode; the original base station refers to a base station corresponding to a last mode of the offline mode when the last mode is the online mode. As an example, the specified period may refer to one day, i.e., one natural day. For example, a day may be divided into a plurality of periods, and a specified period may also refer to any one of the plurality of periods in the day. Illustratively, the specified period of time may also refer to a week, a month, etc.

For example, when the electronic price tag is adjusted from the shutdown mode to the offline mode, if the number of times of network access in the specified period does not exceed the threshold value of the number of times of network access, it may be determined that the electronic price tag satisfies the preset network access condition, otherwise, the preset network access condition is not satisfied. Therefore, frequent network access of the electronic price tag can be avoided to a certain extent, and power consumption of the electronic price tag is reduced.

In an exemplary embodiment, when the electronic price tag is adjusted from the online mode to the offline mode, in the specified determination duration, if any message of the original base station is received in the receiving window and the signal quality of the any message is within the signal quality threshold range, it may be determined that the electronic price tag meets the preset network access condition, or else, the preset network access condition is not met. Wherein, the arbitrary message can activate message, heartbeat message, wake-up message or data message. Therefore, when the communication link between the electronic price tag and the base station is recovered, or the electronic price tag returns to the original base station cell after moving, the network access can be rapidly performed, and the network access speed of the electronic price tag is improved.

When the electronic price tag is adjusted from the online mode to the offline mode, in the specified determination time period, if any message of the original base station is received in the receiving window, and the signal quality of the any message is within the signal quality threshold range, and the number of times of network access in the specified period does not exceed the number of times of network access threshold, the electronic price tag can be determined to meet the preset network access condition, otherwise, the preset network access condition is not met.

In some embodiments, the electronic price tag may receive an activation message sent by the base station on the activation channel, send a network access request message to the base station on at least one common channel, send a network access confirmation query message to the base station on a network access confirmation random channel, and receive a network access confirmation message sent by the base station on the network access confirmation random channel. Therefore, when the electronic price tag moves to the cell corresponding to any base station, the electronic price tag can quickly access the network through the same active channel and common channel, so that the network access efficiency of the electronic price tag is improved.

In some embodiments, the electronic price tag may receive a heartbeat message broadcast by the base station over the data channel. Thus, the electronic price tag can be communicated with any one of a plurality of subnets of any base station through a data channel corresponding to the base station after being networked.

In some embodiments, when the electronic price tag is in the online mode, the wake-up message issued by the base station may be received through the receiving window.

In some cases, the wake-up message may carry a wake-up bitmap, where the wake-up bitmap is determined based on a short address space of any subnet of the base station, and the wake-up bitmap includes a wake-up address for indicating any electronic price tag to wake up. Therefore, in this embodiment, the electronic price tag may determine whether there is a wake-up address corresponding to the price tag address in the network access configuration information in the wake-up bitmap, and if so, may respond to the wake-up message.

In some cases, the wake-up message may carry any one of a price tag OTA upgrade command, a price tag picture data refresh command, or an instruction alert command. In this embodiment, if the wake-up message carries any one of a price tag OTA upgrade command, a picture data refresh command or an instruction prompt command, the price tag picture data refresh, price tag OTA upgrade or instruction prompt may be implemented in response to the wake-up message. Specifically, the method can enter a price tag OTA upgrading state according to a price tag OTA upgrading command, receive electronic price tag upgrading package data issued by a base station based on the price tag OTA upgrading state, and upgrade firmware by using the electronic price tag upgrading package data, so that firmware repair, updating or upgrading of the electronic price tag can be realized, and the stability of the electronic price tag is improved.

Specifically, the price tag picture data refreshing state can be entered according to the price tag picture data refreshing command, price tag picture data issued by the base station is received based on the price tag picture data refreshing state, and refreshing display is carried out by using the price tag picture, so that the price information of the commodity is modified and displayed.

Specifically, the indication reminding state can be entered and maintained according to the indication reminding command and the carried indication reminding duration information. For example, when the electronic price tag enters an indication reminding state, an indication reminding such as LED flashing, buzzer sounding or the like can be performed. Therefore, the position of the electronic price tag can be quickly determined and searched, and the electronic price tag can be conveniently managed. For example, an indication alert close button may be further provided on the electronic price tag, and the electronic price tag may end the indication alert state in response to a close operation of the indication alert close button.

The embodiment of the specification provides an electronic price tag communication method, which can be applied to an electronic price tag communication system. Any base station in an electronic price label communication system may correspond to 1 active channel, 2 common channels, and 3 data channels. The electronic price tag can be in any one of a shutdown mode, an offline mode, a network access mode and an online mode. Referring to fig. 10, the electronic price tag communication method may include the following steps.

Step S1001: the base station may broadcast an activity_ind ACTIVATION message on the ACTIVATION channel with a specified ACTIVATION duration according to the ACTIVATION period, where the ACTIVATION message may carry frequency points of 2 common channels. The activation period may be set by the server, for example, 3610 seconds. The activation time length is designated to be longer than the first sleep time length corresponding to the shutdown mode. Since the active channel is a shared channel for multiple base stations, the base stations need to initiate an active channel occupancy request to the server before occupancy, which determines when it can be used.

Step S1002: when the electronic price tag is in a shutdown mode, if the electronic price tag receives an activation message broadcast by the base station in an activation channel, the electronic price tag can enter an offline mode to perform network access judgment, and network access is prepared.

Step S1003: when the electronic price tag is in an offline mode, if the network access times of the electronic price tag on the same day do not exceed the network access times threshold, the electronic price tag can be adjusted to the network access mode from the offline mode so as to execute the network access interaction flow; if the network access times of the electronic price tag on the same day exceed the threshold value of the network access times, the electronic price tag can be adjusted to be in a shutdown mode from an offline mode.

When the electronic price tag is adjusted from the online mode to the offline mode, the message of the network access base station corresponding to the original online mode is received again, and the signal quality of the message is within the signal quality threshold range, so that the electronic price tag can be adjusted from the offline mode to the online mode.

Step S1004: when the electronic price tag is in the network access mode, a network access interaction flow with the base station can be executed, in the network access interaction flow, if the electronic price tag receives a network access confirmation message issued by the base station, the electronic price tag is successful in network access, the network access mode is adjusted to be in an online mode, and if the electronic price tag does not receive the network access confirmation message of the base station, the electronic price tag is failed in network access, and the network access mode is adjusted to be in an offline mode so as to carry out network access judgment again.

Specifically, when the electronic price tag is in the network access mode to execute the network access interaction flow, the method comprises the following steps:

(1) The electronic price tag broadcasts network access request messages JOIN_REQ on 2 public channels respectively, wherein each network access request message carries a time offset time_offset and a frequency point of a network access confirmation random channel random_channel; the time offset represents an offset from the current time to a designated receiving time, and the designated receiving time represents a set starting time of the electronic price tag receiving the network access confirmation message join_resp. The network entry acknowledgement random channel may be any of the 37 general purpose channels in the BLE band. After the broadcast network access request message is finished, the electronic price tag can keep the dormant state at the power consumption level LP 0.

(2) The base station can receive the network access request message sent by the electronic price tag at any public channel, store the time offset time_offset and the frequency point of the network access confirmation random channel random_channel carried in the network access request message, and send the network access request of the electronic price tag to the server.

(3) If the base station receives a parent base station confirmation instruction issued by the server, the network access configuration information of the electronic price tag can be determined, wherein the parent base station confirmation instruction is used for indicating that the base station is a parent base station of the electronic price tag.

(4) After the electronic price tag finishes the sleep state according to the time offset, wake up at the appointed receiving moment, enter the set network access confirmation random channel, at this moment, in order to reduce the power consumption loss of the electronic price tag, the base station can start the receiver at the set network access confirmation random channel in advance to prepare to receive the network access confirmation query message. For example, the base station may enter the network entry acknowledgement random channel 100 milliseconds before the specified receive time to wait for receipt of the network entry acknowledgement query message.

(5) The electronic price tag sends a network access confirmation query message GET_JOIN_RESP on a network access confirmation random channel, after receiving the network access confirmation message, the base station issues the JOIN_RESP network access confirmation message, and after receiving the network access confirmation message, the electronic price tag can acquire network access configuration information carried by the network access confirmation message, such as base station codes, subnet codes, data channels, price tag addresses and the like, and access the network by using the network access configuration information, and the network access configuration information is adjusted to an online mode by the network access mode, and exits the network access confirmation random channel.

(6) If the electronic price tag does not receive the network access confirmation message within a period of time after the appointed receiving time, the electronic price tag can send the network access confirmation query message to the base station again. The base station may wait for a period of time after sending the join_resp network access confirmation message, for example, may wait for 20ms, if the network access confirmation query message sent again by the electronic price tag is not received, it may determine that the electronic price tag is successful in network access, then exit the network access confirmation random channel, and send network access configuration information to the server, so that the server may determine a mapping relationship between the base station and the electronic price tag based on the network access configuration information.

Step S1005: the base station can broadcast a heartbeat message on each corresponding data channel according to the heartbeat period, wherein the heartbeat time length in each heartbeat period is longer than the second sleep time length corresponding to the online mode.

Step S1006: when the electronic price tag is in the online mode, if any message of the base station is not received in the continuously appointed number of receiving windows, the online mode can be adjusted to the offline mode so as to carry out network access judgment again.

Step S1007: when the electronic price tag is in an online mode, if the electronic price tag receives a wake-up message which is sent by the base station and carries a wake-up bitmap, and the price tag address of the electronic price tag is judged to correspond to the wake-up address in the wake-up bitmap, if so, the electronic price tag can respond to the wake-up message. Illustratively, the wake-up message may carry any one of a price tag OTA upgrade command, a price tag picture data refresh command, or an indication alert command. The electronic price tag can respond to the price tag OTA upgrade command and enter a price tag OTA upgrade state to upgrade the electronic price tag OTA. The electronic price tag can respond to the price tag picture data refreshing command and enter a price tag picture data refreshing state to refresh the price tag picture data. The electronic price tag can enter an indication reminding state in response to the indication reminding command so as to carry out indication reminding such as LED flashing, buzzer ringing and the like, thereby being convenient for searching the electronic price tag.
