Embodiment Construction

[0032] The technical solution of the invention will be described in detail below in conjunction with the accompanying drawings.

[0033] The present invention provides an optimization method for the Bluetooth Mesh remote control system. The basic logical idea of ​​the remote control system is: when the application program (PC end) needs to remotely control the light node, send a control command, through the The MQTT server forwards to the smart device that is also connected to the MQTT server. The smart device sends the message to the proxy node of the Bluetooth Mesh network through the low-power Bluetooth GATT bearer. The proxy node converts the proxy data packet into a Bluetooth Mesh data packet and then passes the message through the broadcast. Direct delivery or forwarding to the controlled node through the relay node, and then perform corresponding operations; when the application program needs to obtain node information, taking the sensor node as an example, after the mes...

Abstract

The invention discloses an optimization method for a Bluetooth Mesh remote control system. The limited retransmission of a data package which does not receive an ack message in a set time is carried out through an ack and a timeout retransmission mechanism, and the reliability of the system can be improved to a certain degree; for the problem that a packet loss retransmission mechanism may cause time delay increase, the queuing time delay of high-priority instructions is reduced through a priority queue algorithm such that the overall time delay of the instructions is reduced. On the premise of ensuring the reliability of remote data transmission, the end-to-end time delay of the high-priority instructions in remote control is effectively reduced such that the method is suitable for widerapplication scenarios, and the value of Bluetooth Mesh in remote control of the Internet of Things is further improved.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things remote control, and in particular relates to an optimization method for a Bluetooth Mesh remote control system. Background technique [0002] Bluetooth is a short-range wireless communication technology and one of the basic technologies of the Internet of Things. Bluetooth technology mainly includes classic Bluetooth and low-power Bluetooth technology. Low-power Bluetooth technology is widely used in many fields such as medical care, sports and fitness, security systems, and sensor Internet of Things. [0003] In order to solve the problems of short transmission distance and poor networking capability of Bluetooth low energy technology, in July 2017, the Bluetooth SIG issued the first version of the Bluetooth Mesh standard specification to achieve global interoperability of the Mesh protocol. Mesh is a new network topology choice for low-power Bluetooth. Compared with the previous poin...
