Node device and internet of things communication subsystem

Abstract

The invention provides a node device and an internet of things communication subsystem; the node device is low in power consumption, and can easily add tasks; the node device comprise a task adding portion, a calculating portion, a task storage portion, a time obtaining portion, a control portion, a concurrent task obtaining portion, a task execution portion and an updating portion; the task adding portion can add tasks according to a cycle frequency and execution periods; the calculating portion calculates the interval time of each task; the task storage portion stores the task, the cycle frequency and the interval time, and ranks same in order; the calculating portion calculates the next wake up time before the node device enters a sleep mode; the task execution portion executes the task corresponding to the minimum interval time; the concurrent task obtaining portion obtains a concurrent executing task, and the task execution portion executes the task; the updating portion updates the task storage portion before the node device enters the sleep mode, and the task storage portion is re-ranked after the updates.

Description

technical field [0001] The invention belongs to the field of the Internet of Things, and in particular relates to a low-power consumption node device and an Internet of Things communication subsystem containing the node device. Background technique [0002] As an important part of the new generation of information technology and an important product of the information age, the Internet of Things has been applied to smart home, factory smart monitoring and other fields, providing great opportunities for people to remotely monitor, manage and control various smart devices. convenience. [0003] The Internet of Things mainly includes two parts: node modules and gateway devices. Each node module can be connected with one or more information collectors of smart devices, so as to receive the operation data information sent by the information collector, or the monitoring instruction information sent by the gateway. On the one hand, the gateway device communicates with the node mo...

Problems solved by technology

[0006] However, sometimes the time interval between several tasks is very short, so the node module has to wake up and sleep continuously. Such frequent wake-up and sleep will not only fail to achieve the purpose of reducing power consumption, but will also increase power consumption

[0007] In addition, during the use of the node module, when a new task needs to be added, the wake-up and sleep programs in the node module are usually rewritten according to the requirements of the new task. The process of adding a new task is cumbersome and time-consuming
