Abstract

The invention discloses a data transmission method and device, computer equipment and a computer readable storage medium, and belongs to the technical field of networks. According to the invention, when first node equipment determines that the message transmission satisfies the first target condition, the data length of the preamble applied when the next message is sent is reduced, so that the time consumption of sending the preamble by the first node equipment is reduced, the equipment energy consumption of the first node equipment is reduced, and the data sending efficiency of the first nodeequipment can also be improved; the occupation of channel resources is reduced, and when the message transmission satisfies the second target condition, the second node device can reduce the time consumption for detecting the lead code next time, thereby improving the detection efficiency of the lead code, and reducing the equipment energy consumption of the second node equipment.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a data transmission method, device, computer equipment and computer-readable storage medium. Background technique [0002] LoRa (Long Range) is one of the LPWAN (Low Power Wide Area Network, Low Power Wide Area Network) communication technologies. It has the characteristics of long data transmission distance and low transmission power consumption, and is widely used in the field of Internet of Things. For example, the LoRa technology is combined with intelligent hardware to build an Internet of Things platform to realize smart cities, smart agriculture, and smart medical care. [0003] At present, CAD (Channel Activity Detection) is introduced in LoRa technology to reduce the power consumption of the device. In the CAD detection mode, the LoRa receiving node will detect the preamble of the air interface under the current spreading factor and detect the preamble It wil...
