Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Bluetooth mesh gateway data aggregation reporting method of the present invention, such as figure 1 As shown, all sub-device changes are cached locally in the mesh gateway; the Mesh gateway compares the aggregated data to be updated of each sub-node; the gateway aggregates a set of data and forwards it to the cloud server, and at the same time reports the difference in device status, and the device status does not change Data is not reported.

[0027] In a preferred embodiment of the present invention, as figure 2 As shown, the Bluetooth Mesh network obtained in the present invention includes 14 Bluetooth node sub-devices, and the sub-devices are surrounded by circles of different sizes, indicating their respective state data changes, and the changes of the sub-devices are all cached locally in the mesh gateway. Such as image 3 As s...

Abstract

The invention discloses a Bluetooth mesh gateway data aggregation reporting method of the invention, which comprises the following steps: step 1, the equipment status of the sub-equipment is reportedto the Bluetooth mesh gateway; step 2, the Bluetooth Mesh gateway caches the status data reported by all the sub-devices locally; 3, the Bluetooth mesh gateway compares the aggregated data to be updated of each sub-device; 4, the data is aggregated into a group by the Bluetooth mesh gateway and forwarded to the cloud server. One set of data includes heartbeat packets. The data format of heartbeatpacket is child device id + device online status + function data + product type. Child device id, device online status, function data, and product type are all represented in one byte. After the MeshGateway powers up, the child device status is synchronized to the cloud server in batches. The device status can be checked at the mobile terminal, such as on-line, on-off status and so on. Remote group control equipment, equipment status gradually synchronized, the final state and local consistency.

Description

technical field [0001] The invention relates to the technical field of bluetooth, in particular to a data aggregation reporting method of a bluetooth mesh gateway. Background technique [0002] The Bluetooth Mesh network is a new network topology of Bluetooth Low Energy (Bluetooth Low Energy, also known as Bluetooth LE) for establishing many-to-many (many:many) device communication. It allows you to create a large-scale network based on multiple devices. The network can contain dozens, hundreds or even thousands of Bluetooth Mesh devices. These devices can transmit information to each other. There is no doubt that such an application form is building automation. Wireless sensor networks, asset tracking and other solutions offer ideal options. [0003] At this stage, Bluetooth mesh devices can only be controlled locally, and the Bluetooth mesh gateway is used to endow the mesh network with remote control functions. However, due to the large number of child nodes in the Blue...
