Internet of Things wireless star network low-power-consumption equipment

Abstract

The invention discloses Internet of Things wireless star network low-power consumption equipment which comprises a concentrator, a plurality of collectors and equipment corresponding to the collectors, and a star network is formed between the concentrator and the collectors; the concentrator compares the collector network retreating quantity value with a network retreating quantity threshold value; and when the condition meets the set condition, the concentrator adjusts the collector network access sequence list, and the collector calculates the wake-up time of the next period according to thedistributed network access sequence number, the number of the accessed collectors, the time interval between the collectors and the uploading time of the previous collector data packet. The whole wake-up period of the concentrator can be dynamically adjusted along with the conditions of network access and network withdrawal, the network communication power consumption is reduced, the electrification time is prolonged, meanwhile, equipment can be directly replaced when the concentrator works abnormally, and the normal work of the collector is not influenced.

Description

technical field [0001] The present invention relates to the technical field of the Internet of Things, and more specifically, to a low-power consumption device of a wireless star network of the Internet of Things. Background technique [0002] The existing wireless star network of the Internet of Things connects many collectors together through the concentrator, and the collectors regularly send data packets to the concentrator according to the time slice polling method. As new collectors join the network, or existing collectors withdraw from the network, the concentrator fails to adjust the polling interval of the collectors, resulting in channel congestion or idle channels, data loss, and increased device power consumption. , Reduce wireless channel utilization and other shortcomings. Abnormal operation of the concentrator will also cause confusion in the sending cycle of the collector. Contents of the invention [0003] The purpose of the present invention is to provi...
