Embodiment 1

[0042] This embodiment provides a BLE cascade network, such as figure 1 As shown, the topology of the cascaded network includes a plurality of independent links, and each link includes a plurality of BLE devices connected step by step, wherein the first-level device and the server establish a link connection through wireless communication; the service The message sent by the terminal is passed to the next-level device of this link step by step through the first-level device to the destination device.

[0043] In this embodiment, the server can be a smart terminal, a smart device central controller, etc., and can issue commands or configurations to any BLE device in the network.

[0044] The BLE cascaded network in this embodiment is different from the mesh topology of the BLE Mesh network in the prior art. The link structure is simplified to form relatively independent links, which can reduce the repeated transmission of messages between devices and eliminate the need for The...

Embodiment 2

[0046] This embodiment provides a link routing method for a BLE cascaded network, which is applicable to the above-mentioned BLE cascaded network, and can reduce broadcasting of data packets in the network.

[0047] Such as figure 2 As shown, the link routing method includes the following steps:

[0048] S11, the server collects link information of BLE devices connected to the network to form a link information table.

[0049] The BLE communication connection is established between the BLE devices to form a link, and the registration is connected to the network, and the server establishes a connection with the first-level BLE device in the link through wireless communication. The BLE device collects the link information of the link, and reports it to the server through the link; the server collects the link information of each BLE device, forms a link information table, and stores it in the memory and / or in the database. The server updates the link information table accordi...

Embodiment 3

[0066] This embodiment provides a link routing device for a BLE cascaded network, including: a BLE device and a server, the BLE device and the server form the BLE cascaded network of the first embodiment above, and are used to implement the above embodiment Two link routing methods.

[0067] The server and the BLE device have the necessary functional modules to execute the above link routing method, which can solve the same technical problem and achieve the same technical effect. Such as image 3 shown.

[0068] The server includes:

[0069] The storage module is used to store the link information of the BLE device connected to the network to form a link information table;

[0070] A routing module, configured to query the link information table for all levels of equipment that need to pass through when the message is sent to the destination device, to form a routing table;

[0071] a data encapsulation module, configured to encapsulate the routing table into the message; ...

Abstract

The invention discloses a BLE cascade network and a link routing method and device thereof, and relates to the technical field of wireless data transmission. The link routing method comprises the following steps: a server collects link information of BLE equipment accessing a network to form a link information table; the server queries each level of equipment through which the message needs to besent to the destination equipment in the link information table to form a routing table; the server encapsulates the routing table into a message, and issues the message to a first-level equipment ineach link; and each level of equipment in the link judges whether the message is processed by the local machine or not according to the routing table, and if not, the message is sent to the next levelof equipment of the link. According to the invention, the network structure is simplified; relatively independent links are formed, repeated transmission of messages among the devices can be reduced,the network topology relation can be mastered through link information collection, the messages carry routing tables, the equipment processes the messages or transmit the messages step by step according to the routing tables, message broadcasting is effectively reduced, and data congestion and network delay are avoided.

Description

technical field [0001] The invention relates to the technical field of wireless data transmission, in particular to a BLE cascaded network and a link routing method and device thereof. Background technique [0002] At present, it involves the routing function of Bluetooth. One of the ways is to extend and extend the Bluetooth signal through a Bluetooth router to realize a large-scale mesh connection and networking of multiple Bluetooth devices. It can extend the Bluetooth transmission distance to 300 meters. The other is the BLE Mesh network, which is composed of Mobile and Node. Mobile is a smart phone, which acts as the control terminal of the Mesh network, and Node is a BLE node device in the network. The BLE Mesh network is implemented by broadcasting. Node A broadcasts the message. When Node B receives the message from Node A, it broadcasts the message from Node A. By analogy, using the infection method, all the All nodes within wireless range receive this message. Ho...
