Problems solved by technology
However, in the case of many device levels, it takes a lot of time whether point-to-point transmission or broadcast transmission is adopted, resulting in low data transmission efficiency. In addition, since many LoRa devices are powered by batteries, the long-term battery Power supply will reduce the power supply voltage of LoRa communication devices, which will reduce the transmission power of individual devices, thus affecting the reliable transmission of data between device levels

Embodiments of the present application provide a Lora-based wireless data transmission method, device, and system, which relate to the field of communication technologies. The method includes: controlling the first device to broadcast the data to be broadcast within the first range, so that the first receiving device within the first range receives the data based on the broadcast; after the first device finishes broadcasting the data to be broadcasted, controlling the second The second device broadcasts the data to be broadcast within the second range; and when the first receiving device within the second range receives less data than the data to be broadcast, the first receiving device receives the data to be broadcast based on the broadcast Data other than received data. Since it can be broadcast by the second device to the second receiving device when the data to be broadcast is broadcast, the first receiving device located within the second range of the second device can receive the missing data based on the broadcast of the second device , which greatly shortens the time-consuming of reissuing and improves the data transmission efficiency of the wireless transmission method.
Description
technical field [0001] The present application relates to the field of communication technology, in particular, to a Lora-based wireless data transmission method, device and system. Background technique [0002] When data transmission between devices is carried out through LoRa wireless communication, the device receiving data will often lose packets due to the constant changes in the communication environment. At this time, it is necessary to use point-to-point transmission or broadcast transmission. Resend the lost data packet to the device receiving the data. However, in the case of many device levels, it takes a lot of time whether point-to-point transmission or broadcast transmission is adopted, resulting in low data transmission efficiency. In addition, since many LoRa devices are powered by batteries, the long-term battery Power supply will reduce the power supply voltage of LoRa communication devices, which will reduce the transmission power of individual devices, t...
