Node and control method thereof, gateway and control method thereof

Abstract

The invention relates to the technical field of electronics, and discloses nodes and a control method thereof, a gateway and a control method thereof. In the embodiment of the invention, the control method of the nodes comprises the following steps: receiving a heartbeat broadcast by the nodes by taking a first preset time length as an interval; if the heartbeat broadcast comprises nodes to be updated which need to be updated before a next heartbeat broadcast and update time corresponding to each node to be updated, then judging whether the nodes belong to the nodes to be updated; and if the nodes belong to the nodes to be updated, then waking up at the corresponding update time, and receiving update data; and if the nodes do not belong to the nodes to be updated, then waking up at the receiving time of the next heartbeat broadcast, wherein the nodes enter a sleep state after receiving the heartbeat broadcast or the corresponding update time is over. Through the embodiment of the invention, the power consumption of the nodes is greatly reduced, and the battery life is prolonged.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a node and its control method, a gateway and its control method. Background technique [0002] A network node refers to a device in the Internet of Things that has an independent address and has the function of transmitting or receiving data. A node can be a single tag or multiple tags in the electronic label system (controlled by an IoT communication node), or it can be other low-power IoT devices, such as sensors, logistics monitoring nodes, storage monitoring nodes and other devices. Every IoT device, that is, a device with its own unique network address is a network node. The entire network is composed of many network nodes. A gateway is also called a network connector or a protocol converter. A gateway can drive multiple nodes. [0003] At present, supermarkets, convenience stores, pharmacies, etc. mostly use paper price tags to display product information. The displ...

AI Technical Summary

Problems solved by technology

[0004] The inventors of the present application found that in the prior art, there are at least the following problems: as a single node in the electronic price tag system, each electronic price tag consumes a large amount of power, and the entire system needs to manually replace the battery frequently, which increases the Operating costs and staff workload
