In view of the above problems, an embodiment of the present invention provides an information display system, in which a master control node and a plurality of tag nodes form a wireless MESH network, and the tag nodes have information display modules, and the information display modules can display information under the control of the master control node, thereby implementing electronic display of information and reducing labor cost. In addition, the wireless MESH network has the advantages of convenient networking, flexible structure, high reliability of data transmission, convenient maintenance and the like, so that the whole information display system is more convenient to use, and the user experience is improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides an information display system, which may include a main control node 11 and a plurality of tag nodes. The master control node 11 and the plurality of tag nodes form a wireless MESH network. Any one of the label nodes comprises an information display module, and the information display module is suitable for displaying information under the control of the main control node 11.
In the wireless MESH network, the connection between any two nodes is a wireless connection. Each node is connected with at least two other nodes, each node is an Access Point (AP), and each node can send and receive data, so that each node has automatic configuration and centralized management capabilities, and management and maintenance of a network are simplified.
In addition, in the wireless MESH network, each node may directly communicate with one or more peer nodes, for example, referring to fig. 1, the main control node 11 may be directly connected to the tag node 121, or may be connected to the tag node 121 through other nodes, so that each node has multiple transmission paths, when one of the transmission paths is congested, data transmission may be automatically performed through other paths, and reliability of data transmission is high.
In addition, when the node is added into the wireless MESH network, the node is only required to be in wireless connection with other nodes in the wireless MESH network, networking is convenient, meanwhile, the structure of the wireless MESH network is more flexible, and when the wireless MESH network is applied specifically, the appropriate number of the nodes can be arranged according to the actually required network coverage range, so that space signal full coverage is realized.
In the embodiment of the invention, as the main control node 11 and the plurality of tag nodes form the wireless MESH network, the whole information display system is convenient to network, flexible in structure, high in data transmission reliability and convenient to maintain while electronic information display is realized, so that the use is more convenient.
In the specific implementation, in the areas such as supermarkets which need a small network coverage, the information display system can only consist of the main control node 11 and the label nodes, wherein the number of the label nodes can be set according to the actual needs,
for example, as shown in fig. 1, 7 tag nodes may be provided, which are tag nodes 121 to 127, respectively. At this time, the main control node 11 may be connected to some or all of the tag nodes 121 to 127, and the two tag nodes may also be connected to each other, and data sent by the main control node 11 to the tag node 125 may be transmitted through the connection between the main control node 11 and the tag node 125. The data sent by the main control node 11 to the tag node 127 can be transmitted through the connection between the main control node 11 and the tag node 124 and the connection between the tag node 124 and the tag node 127.
In an embodiment of the present invention, in order to increase a network coverage area to be suitable for a large area such as a mall, the information display system may further include a relay node. The relay node, the master control node 11 and the plurality of tag nodes form the wireless MESH network. At least one of the label nodes is connected with the main control node 11 through the relay node.
The number of the relay nodes can be set according to actual needs. For example, when the network coverage is large, a plurality of relay nodes may be provided to improve the stability of the network. Each tag node may be connected to the main control node 11 through a relay node. Of course, the tag node may be directly connected to the master node 11 without passing through the relay node.
For example, referring to FIG. 2, the information display system may further include relay nodes 131-135. The tag node 128 is connected to the master node 11 via the relay nodes 133 and 135. The relay node 134, although having the capability of relaying transmissions, may also be used as a label node, i.e. may also be used for displaying information.
In addition, the number of tag nodes connected to each relay node is not limited. For example, as shown in fig. 2, the number of connected label nodes is 4 for the relay node 135, 5 for the relay node 132, and 7 for the relay node 133.
In a specific implementation, the wireless MESH network formed by the information display system may be a MESH network based on any one of wireless communication protocols. For example, each node in the wireless MESH network can be provided with a wifi communication module, and the nodes are wirelessly connected through wifi to form the MESH network.
In an embodiment of the present invention, in order to reduce power consumption of each node, prolong a service life of each node, and further reduce cost, the wireless MESH network may be a bluetooth-based MESH network, that is, each node may be connected to other nodes through bluetooth, so as to form a MESH network.
Fig. 3 is a schematic structural diagram of a tag node according to an embodiment of the present invention. Referring to fig. 3, the tag node may include a bluetooth control module 31 and an information display module 32. Wherein:
the bluetooth control module 31 is adapted to perform bluetooth connection with other nodes in the wireless MESH network, receive data information sent by other nodes in the wireless MESH network, and send the received data information to the information display module 32.
The information display module 32 may display the received data information.
In a specific implementation, the bluetooth control module 31 may be a Micro Controller Unit (MCU) supporting bluetooth MESH. The MCU can be connected with other nodes through Bluetooth, and then receives data information sent by other nodes.
In a specific implementation, the information display module 32 may be a display screen, and the display screen may display the received data information. The data information may be price information, discount information, etc. of the commodity.
In a specific implementation, the tag node or the relay node may be a fixed electronic device having an information display module, or may be a mobile device having an information display module, such as a mobile phone, a notebook, a tablet computer, and a vehicle-mounted computer, and is not limited specifically. In scenes such as large exhibition places and the like, the label nodes can be manufactured into large display terminals, and in scenes such as markets, supermarkets and the like, the label nodes can be manufactured into miniature display terminals and can be specifically determined according to the amount of data information to be displayed.
In a specific implementation, the main control node 11 is adapted to control the tag node and the relay node to join the wireless MESH network.
Specifically, referring to fig. 2, when joining the wireless MESH network, the tag node 128 performs bluetooth connection with the relay node 133, and sends a network access request to the main control node 11 through the relay node 133 and the relay node 135. After receiving the access request, the main control node 11 performs authentication on the tag node 128, and allows the tag node 128 to join the wireless MESH network after the authentication is passed.
Meanwhile, the main control node 11 will assign an identification information to the tag node 128, and the identification information will be bound with the information of the article to be displayed by the tag node 128. How to bind the tag node 128 identification information with the item information to be displayed by the tag node 128 can be achieved in various ways, for example, the tag node 128 identification information can be bound with the item information by an input operation of a user at the main control node 11.
In a specific implementation, the master node 11 may further delete the tag node or the relay node from the wireless MESH network.
Specifically, referring to fig. 2, the master node 11 may receive a command input by a user, and delete the tag node 128 or the relay node 134 indicated in the input command from the wireless MESH network. When the input instruction indicates deletion of the relay node 132, for a tag node connected to the relay node 132, connection with other relay nodes is possible.
In a specific implementation, referring to fig. 2, the information display system may further include a database 14, where the database 14 is adapted to store the identification information of each tag node and the corresponding display information.
In an embodiment, taking the tag node 128 as an example, when the tag node 128 accesses the wireless MESH network, the master node 11 allocates identification information to the tag node 128, where the identification information can uniquely identify the tag node 128. The master node 11 can bind the identification information of the tag node 128 with the corresponding display information and store it in the database 14.
In other embodiments, the information stored in the database 14 may be obtained in other manners. For example, the identification information of the tag node and the corresponding display information may be directly stored in the database 14 by the user, rather than being transmitted through the main control node 14.
In an embodiment of the present invention, as shown in fig. 2, the main control node 11 is further adapted to update the identification information of the tag node and the corresponding display information stored in the database 14. For example, when the display information bound by the tag node 128 changes, the updated display information may be obtained by the main control node 11 and stored in the database 14.
In a specific implementation, the main control node 11 may obtain the updated display information in a variety of ways. For example, the updated display information may be obtained through an input operation of a user, that is, the updated display information is directly input into the main control node 11 by the user.
In an embodiment of the present invention, in order to facilitate the user to use, other nodes in the wireless MESH network may send the updated display information to the main control node 11. The other nodes may be handheld terminal devices. Because the handheld terminal device is usually carried by the user, the information displayed by the label node can be updated in real time through the handheld terminal device, and the updating efficiency is improved.
For example, referring to fig. 2, the relay node 134 may be a mobile phone, and the updated display information is sent to the main control node 11 through the relay node 134.
In a specific implementation, when receiving the updated display information, the main control node 11 may obtain the tag node to be updated based on the updated display information, and may further send the updated display information to the tag node to be updated. Meanwhile, the master node 11 updates the information stored in the database 14 accordingly.
Compared with the existing paper price label, the information display system in the embodiment of the invention can add tens of thousands of electronic labels into the network by relying on the strong networking capability of the Bluetooth MESH network, so as to update the price and discount information of the commodity in real time, realize online and offline synchronization, avoid the inconsistency between the price and the data in the database and reduce the occurrence of errors. And moreover, by utilizing the low-power-consumption node characteristic of the Bluetooth MESH network, one tag can be used for years, the consumption of paper is reduced, the energy is saved, the environment is protected, and all tag nodes can be maintained by only a few people, so that the labor input is greatly reduced.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
