A low-power wireless communication method for monitoring nodes and aggregation gateways

Abstract

The invention discloses a method of low-power consumption wireless communication between a monitoring node and a convergence gateway. The method at least comprises three stages of monitoring node registration, authentication and encryption and data transmission. In the data transmission stage, the monitoring node organizes and stores acquired sensor data in a data grouping mode. In order to improve the transmission efficiency and reduce the power consumption, grouped sensor data are firstly segmented or merged to adapt to the characteristics of monitoring business; and then, wireless transmission protocol adaptation is carried out on business data frames to select the best wireless transmission protocol, and the best transmission performance and the energy-saving efficiency are thus acquired. In order to acquire better energy-saving efficiency, the monitoring node continuously learns and improves a sleep awakening control strategy of a node radio frequency unit according to safety assessment and energy consumption assessment results to reduce the activity time of the radio frequency unit. The sleep awakening control with a learning ability can better adapt to various different intelligent security application scenes, and the energy consumption efficiency and the system performance are thus maximized.

Description

【Technical field】 [0001] The invention belongs to the fields of wireless communication, smart home and smart security, and relates to a low-power wireless communication method used between a monitoring node and a convergence gateway. 【Background technique】 [0002] In the field of smart home and smart security, general monitoring and control systems usually use wired systems. Take natural gas leakage monitoring in the kitchen as an example. The traditional monitoring method uses an externally powered gas sensor device placed near the gas meter. When a leak is detected, an audible and visual alarm will be activated. Although such a system can detect leakage events relatively safely, the monitored process data and detection results cannot be output, let alone known by users in real time, and there is no communication interface between system equipment and users. [0003] Taking lighting control as an example, traditional intelligent lighting control is usually controlled dire...
