The invention discloses a network access method, which belongs to the technical field of Lora equipment networking, and comprises the following steps: a network access step: setting a transmission spread spectrum factor and a receiving spread spectrum factor, randomly selecting a transmission channel, carrying out channel activity detection on the selected transmission channel, if the channel is detected to be idle, transmitting a network access message, waiting for distributing a short address, and if the channel is not idle, sending the network access message; if the short address distribution is not overtime, the network access is successful; a spread spectrum factor self-adaption step: using the spread spectrum factor which is successfully accessed to the network, entering a receiving mode, randomly selecting a sending channel if a preset sending time is reached, carrying out channel activity detection on the selected sending channel, and sending data if the channel is idle; according to the Lora equipment ad hoc network method and the upgrading system, the energy consumption of operation is reduced, the optimization of equipment operation is realized, the high transmission efficiency is realized through the definition improvement of the message, the error rate of communication is reduced, the automatic upgrading is realized, and the working efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of Lora equipment networking, and particularly relates to a Lora equipment self-organizing network method and an upgrading system. Background technique [0002] Now we are in the era of the Internet of Things. With the development of Internet of Things technology, wireless communication technology has also received great attention. Among various wireless communication technologies, not only 5G technology with higher speed and stability is required, but also we LPWAN technology with low power consumption, long distance, and large connection is also required. The development of diversity enables us to choose suitable communication technologies according to different situations; among them, Lora technology is favored by its unique flexibility. Recognition by the majority of IoT users; [0003] LoRa is widely deployed in smart communities, smart homes and buildings, and smart meters because of its low power con...
