Problems solved by technology

However, the frequency of events that need to be detected and processed by the node in the specific environment may be constantly changing
If the sleep time is too long relative to the interval between events, it will cause the node to miss some events and affect the overall performance; if the sleep time is too short relative to the interval between events, it will cause the node to wake up unnecessary. Waste the energy of the node, resulting in a reduction in the working life of the node

Embodiment Construction

[0023] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0024] figure 1 is a flowchart of a method for periodically waking up a node according to an embodiment of the present invention. This method can be used in various devices such as wireless sensors, which are also referred to as nodes in the present invention, such as figure 1 As shown, the method may include the following steps.

[0025] In step S110, periodically sleep the node according to the sleep duration.

[0026] For example, initially, the sleep duration may be a configured value, and a sleep timer is set in the node. Turn on the dormancy timer to start counting. During the dormancy time, the node stops all or part of its functions. When the dormanc...

Abstract

The invention relates to the technical field of electronic equipment and discloses a method and a device for periodically awaking a node. The method comprises steps as follows: periodical dormancy is performed on the node according to dormancy duration; the node is awakened to detect events every time dormancy time arrives; a time interval between the event and the last event is determined when the events are detected; the dormancy duration is changed according to the determined time intervals between multiple events when the time intervals between multiple events are determined. With the adoption of the method, the dormancy duration can be automatically adjusted according to changes of the time intervals of the events, accordingly, the working performance of the node is improved, and the service life of the node can be prolonged.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a method and device for periodically waking up a node. Background technique [0002] In the prior art, some devices are powered by batteries, such as wireless sensors in a wireless sensor network, these devices need to use a sleep mechanism to prolong their service life due to the limitation of power supply capability. Devices in these networks may be referred to as nodes. [0003] In the prior art, the dormancy mechanism adopted for the nodes in the network is a way of setting a fixed dormancy duration and performing periodic dormancy according to the dormancy duration. However, the frequency of events that need to be detected and processed by nodes in a specific environment may be constantly changing. If the sleep time is too long relative to the interval between events, it will cause the node to miss some events and affect the overall performance; if the...
