Description

Energy-saving state control method, device, equipment, system and medium Technical Field The present application relates to the field of optical communications technologies, and in particular, to a method, an apparatus, a device, a system, and a medium for controlling an energy saving state. Background In an optical access network, the problem of power consumption of optical communication devices is receiving a great deal of attention. In the related art, some energy-saving management policies are formulated for ONUs in a PON (passive optical network, PON) system. In case the optical line terminal (optical LINE TERMINAL, OLT) allows the optical network unit (optical network unit, ONU) to enter the power saving state, if the ONU needs to enter the power saving state, a sleep request message is sent to the OLT to enter the power saving state. And in the energy-saving state, the ONU is circularly switched between an awake state and a low-power-consumption state, wherein in the low-power-consumption state, part of modules of the ONU are fixedly closed, and part of modules are periodically opened, so that the power consumption of the ONU is reduced. However, this power saving approach is not applicable to a master device in a fiber-to-room (fiber to the room, FTTR) network. Disclosure of Invention The application provides a control method, a device, equipment, a system and a medium for energy-saving state, which are beneficial to reducing the power consumption of a main device in FTTR networks. In a first aspect, the present application provides a method for controlling an energy saving state. The control method of the power saving state is performed by the master device. The control method of the energy-saving state comprises the steps that a master device determines that a plurality of slave devices connected with the master device are in a first energy-saving state, and the master device enters a second energy-saving state. Since the master device is connected not only to an Optical Line Terminal (OLT) but also to a plurality of slave devices, it is not possible to directly adopt an ONU energy saving system in the PON system. In the application, when the plurality of slave devices connected with the master device are in the first energy saving state, the master device also enters the second energy saving state, so that the power consumption of the master device can be reduced. Optionally, the second power saving state includes a light sleep state (LIGHT SLEEP), a deep sleep (DEEP SLEEP), and an awake (aware) state. That is, the master device enters a second power saving state including the master device transitioning between a light sleep state and an awake state, or the master device transitioning between a deep sleep state and an awake state. Wherein, when the main device is in a light sleep state or a deep sleep state, all or part of the modules of the main device are closed. By turning off all or part of the modules of the main device, the power consumption of the main device in the light sleep state or the deep sleep state is reduced. While transitioning the master device between the sleep state (including the light sleep state or the deep sleep state) and the awake state may enable the master device to receive and transmit data in the awake state, thereby enabling exit from the second power saving state when needed. Optionally, the transition between the light sleep state and the wake state comprises the steps of transitioning from the wake state to the light sleep state when a first timer is overtime and a slave device in a doze state exists in the plurality of slave devices, wherein the first timer is used for indicating the duration that a master device is in the wake state, and transitioning from the light sleep state to the wake state when a second timer is overtime, and the second timer is used for indicating the duration that the slave device is in the light sleep state. And controlling the duration of the main equipment in the awakening state and the light sleep state by using the first timer and the second timer so as to realize cyclic transition between the light sleep state and the awakening state. Optionally, the switching between the deep sleep state and the wake state comprises switching from the wake state to the deep sleep state when a first timer times out and no slave device in a doze state exists in the plurality of slave devices, wherein the first timer is used for indicating the duration that the master device is in the wake state, and switching from the deep sleep state to the wake state when a second timer times out, and the second timer is used for indicating the duration that the slave device is in the deep sleep state. And controlling the duration of the main equipment in the awakening state and the light sleep state by using the first timer and the second timer so as to realize cyclic transition between the light sleep state and the awakening state. Here, the deep sleep state
