US 10,952,143 B2 · Sleeping and wake-up methods and apparatuses of master-slave network, and power saving system of master-slave network

Abstract

Example sleeping and wake-up methods and apparatuses of a master-slave network, and a power saving system of a master-slave network, are described. One example method includes obtaining running statuses of slave devices on links from a link management list. A target device is determined. The target device is a slave device whose running status is idle. If running statuses of the target slave device to an end slave device on a link on which the target slave device is located are all idle, it is determined that a sublink from the target slave device to the end slave device on the link on which the target slave device is located is a target sublink. A power saving message is sent to at least one slave device on the target sublink, so that the slave device enters a sleep and listen state when receiving the power saving message.

Dependent claims

A sleeping method in a master-slave network, wherein the master-slave network comprises a master device, a first slave device and a second slave device, wherein the first slave device is a lower level slave device connected to the master device and the second slave device is a lower level slave device connected to the first slave device, and wherein the method comprises:

obtaining, by the master device, running statuses of the first slave device and the second slave device;
determining, by the master device, the second slave device as a target slave device, wherein a running status of the target slave device is idle;
and
sending, by the master device, a power saving message to at least one of the first slave device or the second slave device in response to determining that the second salve device is the target slave device and that a running status of the first slave device is idle, wherein the at least one of the first slave device or the second slave device enters a sleep and listen state, wherein the sleep and listen state is a running status indicating that signal transmission is disabled.

A wake-up method in a master-slave network, wherein the master-slave network comprises a master device, a first slave device and a second slave device, wherein the first slave device is a lower level slave device connected to the master device and the second slave device is a lower-level slave device connected to the first slave device, and wherein the method comprises:

determining, by the master device, according to one of detected radio-frequency signal strengths and a received detection request, whether to perform wake-up, wherein the detection request is used to connect to the master-slave network;
switching to an operating state in response to determining to perform wake-up, wherein the operating state is a running status indicating that signal transmission is enabled;
and
waking up the first slave device and the second slave device.

1 more element

A sleeping apparatus in a master-slave network, wherein the master-slave network comprises a master device, a first slave device and a second slave device, wherein the first slave device is a lower level slave device connected to the master device and the second slave device is a lower-level slave device connected to the first slave device, and wherein the apparatus comprises:

at least one processor;
a memory storing instructions executable by the at least one processor, wherein the instructions, when executed by the at least one processor, instruct the at least one processor to obtain running statuses of the first slave device and the second slave device and to determine the second slave device as a target slave device, wherein a running status of the target slave device is idle;
and
a transmitter, configured to send a power saving message to one of the first slave device and the second slave device in response to determining that the second salve device is the target slave device and a running status of the first slave device is idle, wherein the at least one of the first slave device or the second slave device enters a sleep and listen state, wherein the sleep and listen state is a running status indicating that signal transmission is disabled.
