Abstract

The invention provides a data acquisition method and device based on an LORA low-power-consumption wireless communication technology, and relates to the field of electronic communication engineering,and the method comprises the following steps: 1, enabling a gateway to send a polling instruction to a terminal node; 2, the terminal node intermittently monitoring a polling instruction, and if the channel frequency of the received polling instruction is consistent with that of the local machine, the terminal node entering a sleep awakening mode; if the channel of the received polling instructionis inconsistent with the local machine, the terminal node continuing to monitor the polling instruction intermittently; 3, after entering the sleep awakening mode, the gateway node entering a sleep state, and the RTC performing timing according to the acquisition period to awaken the terminal node to receive data and sending the data to the gateway; and step 4, when the gateway receives the data,storing the data and then clearing the data. On the basis of a time division multiple access technology, a synchronous locking method is adopted, so that the awakening time of the device is minimized, and the energy consumption of the device is greatly reduced.

Description

technical field [0001] The invention relates to the field of electronic communication engineering, in particular to a data acquisition method and device based on LORA low-power wireless communication technology. Background technique [0002] LORA wireless communication technology is a wireless communication technology based on spread spectrum modulation technology. It has the advantages of long transmission distance, low transmission power consumption, and strong anti-interference performance. It is mainly used in harsh environments such as agricultural monitoring and industrial control. Nodes require high processing power and power consumption. [0003] Patent application number: 201510794196.0 Chinese patent discloses a low-power wireless network implementation method based on LORA wireless modules. Each terminal node maintains a work-sleep time timer by itself, and wakes up the node through the timer. When the node is woken up After entering the CAD mode, taking advantag...
