Description

TECHNICAL FIELD

The present disclosure relates to a technical field of electronic shelf label communications, and particularly to an electronic shelf label and an electronic shelf label system, and a method for processing data.

BACKGROUND

The core technologies of the traditional electronic shelf label data communication are generally based on 2.4G, WIFI, Bluetooth, zigbee, Sub1G, infrared, etc. However, those communication modes have defects. For example, the 2.4G communication mode is based on the 2.4G private protocol to communicate, and the development of the whole application layer and service layer can be extended into cloud management. However, electronic shelf labels in different regions can only be updated based on the smallest unit of stores. The electronic shelf label of each store has to rely on its own wireless private AP (Access Point), and the number of electronic shelf labels is directly proportional to the number of the APs to be deployed, which is not only high in cost, but also difficult for later maintenance upgrade and management. The Bluetooth communication mode has a large power consumption, the Sub1G communication mode has few channels, the infrared communication mode has a high requirement for a network layout that cannot be obstructed, and the WIFI coverage is narrow. Therefore, the communication effects of the above communication modes need to be improved.

In summary, the traditional electronic shelf label data communication has problems of high costs of installation and later maintenance in stores, and poor communication effect.

DESCRIPTION OF EMBODIMENTS

For a clear understanding of the objectives, technical features and effects of the embodiments of the present invention, specific embodiments will now be described with reference to the drawings. The described embodiments are intended only to schematically illustrate and explain this invention and do not limit the scope of this invention.

FIG. 1 is a schematic diagram of an electronic shelf label in an embodiment of the present disclosure. As illustrated in FIG. 1, the electronic shelf label comprises: an NB-IoT network module configured to:

• • receive task data from a server and/or send electronic shelf label data to the server through an NB-IoT network; and
  • send the task data received through the NB-IoT network to a controller and/or receive the electronic shelf label data sent by the controller; and
  • the controller, which is configured to execute a task based on the task data, and/or send the electronic shelf label data to the NB-IoT network module.

In the embodiment of the present disclosure, the NB-IoT network module receives the task data from and/or sends the electronic shelf label data to the server through the NB-IoT network; sends the task data received through the NB-IoT network to the controller and/or receives the electronic shelf label data sent by the controller; the controller executes the task based on the task data and/or sends the electronic shelf label data to the NB-IoT network module. In the electronic shelf label, it is unnecessary to install or maintain any AP, so the cost is low. The coverage of the B-IoT network is wide, so the communication effect of sending and receiving data through the NB-IoT network is improved.

In the electronic shelf label, the electronic shelf label data may include many kinds, such as heartbeat data of the electronic shelf label, stored content, identifier, size information, etc. The NB-IoT (Narrow Band Internet of Things) is an important branch of the Internet. The NB-IoT network, built in a cellular network, consumes a bandwidth of only about 180 KHz and can be directly deployed in a GSM network, a UMTS network or an LTE network to reduce a deployment cost and realize a smooth upgrade. The NB-IoT network, also known as a Low-Power Wide Area (LPWA) network, supports a cellular data connection of a low-power device in a wide area network. The NB-IoT network supports an efficient connection of a device with a long standby time and a high requirement for network connection. A battery life of an NB-IoT device can be increased to at least 10 years, while a very comprehensive coverage of an indoor cellular data connection can be provided. Therefore, the embodiments of the present disclosure can achieve a good communication effect by receiving the task data from and/or sending the electronic shelf label data to the server through the NB-IoT network. In the embodiments of the present disclosure, the NB-IoT network module is a universal interface, which can establish a communication relationship with any communication manufacturer, and has no limitation.

In one embodiment, the controller is further configured to generate network registration information, and send the network registration information and electronic shelf label identification information to the NB-IoT network module;

• • the NB-IoT network module is further configured to send the network registration information and the electronic shelf label identification information to the server through the NB-IoT network, receive and forward electronic shelf label registration result data to the controller, and receive the task data from and/or send the electronic shelf label data to the server through the NB-IoT network, in response to the electronic shelf label registration result data indicating a successful registration.

In the above embodiment, after the electronic shelf label is powered on, the controller may firstly check whether the electronic shelf label has been registered in the NB-IoT network, and generate the network registration information if the check result indicates that the electronic shelf label has not been registered, and send the network registration information and the electronic shelf label identification information to the NB-IoT network module. Next, the NB-IoT network module sends the network registration information and the electronic shelf label identification information to the server through the NB-IoT network to register the electronic shelf label, and then the NB-IoT network module receives and forwards the electronic shelf label registration result data to the controller. If the check result indicates that the electronic shelf label has been registered, the task data may be received from and/or the electronic shelf label data may be sent to the server directly through the NB-IoT network.

In specific implementation, the electronic shelf label may support other communication modes besides the communication through the NB-IoT network, and one embodiment will be given below.

In one embodiment, the electronic shelf label further comprises an NFC module configured to:

• • receive task data from and/or send electronic shelf label data to an NFC device or an APP device;
  • send the task data to the controller and/or receive the electronic shelf label data sent by the controller.

In the above embodiment, the NFC (Near Field Communication) is a short-range and high-frequency radio technology, which operates at a frequency of 13.56 MHz in a distance of 20 cm, with a transmission speed of 106 Kbit/s, 212 Kbit/s or 424 Kbit/s. At present, the near-field communication has passed the ISO/IEC IS 18092 international standard, the ECMA-340 standard and the ETSI TS 102 190 standard. The NFC adopts active and passive reading modes. The NFC device is generally an NFC chip, while software of the NFC chip can be programmed independently with strong universality and consistency, and can be developed by users according to actual needs. APP is an abbreviation of ‘application’, which usually refers to application software on a mobile phone, or is called as a mobile client. In addition, there are many online APP development platforms. The NFC module can receive the task data sent by the NFC device or the APP device, and then send the task data to the controller, which executes a task based on the task data. In addition, the NFC module can also receive the electronic shelf label data sent by the controller, and then send the electronic shelf label data to the NFC device or the APP device. The NFC module enables the communication mode of the electronic shelf label to be more flexible, thereby being suitable for different scenes.

In one embodiment, the controller is further configured to:

• • control the electronic shelf label into a low power consumption state or a wake-up state according to a preset wake-up mode which comprises a periodic wake-up mode and a timed wake-up mode;
  • perform, when the electronic shelf label is in the wake-up state, a compression process on the electronic shelf label data to generate a compressed package of the electronic shelf label data.

In the above embodiment, when the preset wake-up mode is the periodic wake-up mode, a wake-up period may be dynamically configured by a user according to his own business requirement, e.g., a maximum wake-up period may be configured as 2 weeks, or a default wake-up period may be adopted, such as 24 hours. When the preset wake-up mode is the timed wake-up mode, it may be configured to wake up the electronic shelf label at a specific moment in a specific time zone. When the electronic shelf label is controlled to be in the low power consumption state, the power consumption of the electronic shelf label can be reduced and the service life thereof can be prolonged. In addition, when the electronic shelf label is in the wake-up state, the electronic shelf label data is compressed so as to be subsequently sent in the form of a compressed package, thereby improving sending efficiency, saving sending time, and reducing power consumption of the electronic shelf label.

In one embodiment, the NFC module is further configured to:

• • wake up the electronic shelf label upon a preset wake-up condition, when the electronic shelf label is in the low power consumption state.

In the above embodiment, the NFC module wakes up the electronic shelf label upon the preset wake-up condition, which means a forced external wake-up of the electronic shelf label, and the preset wake-up condition can be formulated according to actual needs.

In one embodiment, the NB-IoT network module is further configured to:

• • stop receiving and sending the task data and the electronic shelf label data, when the electronic shelf label is in the low power consumption state;
  • receive the task data from and/or send the electronic shelf label data to the server in batches through the NB-IoT network, when the electronic shelf label is in the wake-up state.

In the above embodiment, when the electronic shelf label is in the low power consumption state, the reception and sending of the task data and the electronic shelf label data are stopped, i.e., the NB-IoT network module is disabled and shut down, thereby reducing the power consumption of the electronic shelf label and prolonging the service life thereof. When the electronic shelf label is in the low power consumption state, it is necessary to receive and send data. In order to prevent the service life of the battery module of the electronic shelf label from being reduced due to the long-term data reception by the electronic shelf label, a manner of receiving and sending data in batches may be adopted, i.e., the data may be received from and sent to the server in batches through the NB-IoT network, including the reception of the task data and/or the sending of the electronic shelf label data on a time basis or a volume basis. The above manner can ensure that no data will be lost while prolonging the service life of the battery module.

In one embodiment, the NB-IoT network module is further configured to:

• • receive a compressed package of the task data sent by the server in batches through the NB-IoT network, and/or send the compressed package of the electronic shelf label data to the server in batches through the NB-IoT network, when the electronic shelf label is in the wake-up state.

The above manner of receiving the task data and sending the electronic shelf label data in the form of compressed package can greatly reduce the sending and receiving time, improve sending efficiency and save power consumption of the electronic shelf label.

In one embodiment, the NB-IoT network module is further configured to:

• • obtain the compressed package of the electronic shelf label data corresponding to a transmission breakpoint, and send the compressed package corresponding to the transmission breakpoint to the server in batches through the NB-IoT network, when the electronic shelf label is in the wake-up state.

The sending process of the compressed package of the electronic shelf label data is a resume transmission process from a breakpoint, which records a last data transmission interruption point, i.e., a transmission breakpoint, identify the compressed package of the electronic shelf label data corresponding to the transmission breakpoint, and re-sends the compressed package of the electronic shelf label data corresponding to the transmission breakpoint in batches. The above process can prevent the loss of the electronic shelf label data in the transmission process.

In one embodiment, the NFC module is further configured to:

• • stop receiving and sending the task data and the electronic shelf label data, when the electronic shelf label is in the low power consumption state;
  • receive the task data from and/or send the electronic shelf label data to the NFC device or the APP device in batches, when the electronic shelf label is in the wake-up state.

In the above embodiment, when the electronic shelf label is in the low power consumption state, the NFC module stops receiving and sending the task data and the electronic shelf label data, i.e., the NFC module is disabled, thereby reducing the power consumption of the electronic shelf label and prolonging the service life thereof. When the electronic shelf label is in the low power consumption state, it is necessary to receive and send data. In order to prevent the service life of the battery module of the electronic shelf label from being reduced due to the long-term data reception by the electronic shelf label, a manner of receiving and sending data in batches may be adopted, i.e., receiving the task data from and/or sending the electronic shelf label data to the NFC device or the APP device in batches, including the reception of the task data and/or the sending of the electronic shelf label data on a time basis or a volume basis. The above manner can ensure that no data will be lost while prolonging the service life of the battery module.

In one embodiment, the NFC module is further configured to:

• • receive a compressed package of the task data of the NFC device or the APP device in batches, and/or send the compressed package of the electronic shelf label data to the NFC device or the APP device in batches, when the electronic shelf label is in the wake-up state.

The above manner of receiving the task data and sending the electronic shelf label data in the form of compressed package can greatly reduce the sending and receiving time, improve sending efficiency and save power consumption of the electronic shelf label.

In one embodiment, the NFC module is further configured to:

• • obtain the compressed package of the electronic shelf label data corresponding to a transmission breakpoint, and send the compressed package of the electronic shelf label data corresponding to the transmission breakpoint to the NFC device or the APP device in batches, when the electronic shelf label is in the wake-up state.

The sending process of the compressed package of the electronic shelf label data is a resume transmission process from a breakpoint related to the NFC module, which records a last data transmission interruption point, i.e., a transmission breakpoint, identify the compressed package of the electronic shelf label data corresponding to the transmission breakpoint, and re-sends the compressed package of the electronic shelf label data corresponding to the transmission breakpoint in batches. The above process can prevent the loss of the electronic shelf label data in the transmission process.
