Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0032] An embodiment of the present invention provides a data transmission method, which can be applied to a LoRa (Long Rang, long-range) communication system. The LoRa communication system is a communication system based on LoRa technology. The LoRa communication system is a long-distance, low-power, low-speed wireless communication system. Such as figure 1 As shown, it is a frame diagram of the LoRa communication system provided by this embodiment, including a gateway device, a s...

Abstract

Embodiments of the invention provide a method and a device for transmitting data and belong to the technical field of communication. The method is applied to a gateway device in a LoRa communication system. The method comprises the following steps of receiving uplink data sent by terminal equipment; sending a terminal uplink message carrying the uplink data to a server; and if a terminal downlinkmessage sent by the server is received within the preset time and the terminal downlink message carries downlink data corresponding to the uplink data, sending the downlink data to the terminal equipment. Through adoption of the method and the device, the message interaction between the gateway device and the server can be simplified, the time for message interaction is reduced and the data transmission efficiency is improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for transmitting data. Background technique [0002] With the development of communication technology, the application of LoRa (Long Rang, long range) technology is becoming more and more extensive. LoRa technology is a wireless modulation technology used in long-distance, low-power, low-speed applications. [0003] In the LoRa communication system, the terminal device can communicate with the server through the gateway device, and the LoRa GWMP (Gateway Message Protocol, Gateway Information Protocol) protocol can be used for communication between the gateway device and the server. According to this protocol, the gateway device and the server The communication process can be as follows: the gateway device receives the uplink data sent by the terminal device, and then sends a terminal uplink message (such as PUSH_DATA) carrying uplink da...
