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 optical access networks, such as passive optical networks (passive optical network, PON), the problem of power consumption of optical communication devices is of great concern. The PON system comprises an Optical Line Terminal (OLT) and a plurality of optical network units (optical distribution network, ONUs), wherein the OLT and the ONUs are connected through an optical distribution network (optical distribution network, ODN). In the related art, some energy-saving management policies are formulated for ONUs. Under the condition that the OLT allows the ONU to enter the energy-saving state, if the ONU needs to enter the energy-saving state, a sleep request message is sent to the OLT to enter the energy-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, there is still a shortage of energy saving management for the OLT. Disclosure of Invention The application provides a control method, a device, equipment, a system and a medium for an energy-saving state, which are beneficial to reducing the power consumption of an OLT. 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 OLT. The control method of the energy-saving state comprises the steps that the OLT determines that a plurality of ONUs connected with the OLT are in a first energy-saving state, and the OLT enters a second energy-saving state. In the application, when the plurality of ONUs connected by the OLT are in the first energy-saving state, the OLT also enters the second energy-saving state, so that the power consumption of the OLT can be reduced. Optionally, the second power saving state includes a low power state (low power) and a wake state (away). That is, the OLT enters a second power-saving state, including the OLT transitioning between a low-power state and an awake state. And when the OLT is in a low-power consumption state, all or part of the modules of the OLT are closed. By turning off all or part of the modules of the OLT, the power consumption of the OLT in the low-power state is reduced. The OLT is configured to switch between the low power state and the awake state, so that the OLT can receive and transmit data in the awake state, and can exit the second power saving state when needed. Optionally, the switching between the low power consumption state and the wake-up state comprises switching from the wake-up state to the low power consumption state when a first timer is timed out, wherein the first timer is used for indicating the duration of the OLT in the wake-up state, and switching from the low power consumption state to the wake-up state when a second timer is timed out, and the second timer is used for indicating the duration of the ONU in the low power consumption state. And controlling the duration of the OLT in the wake-up state and the low-power consumption state by using the first timer and the second timer so as to realize cyclic conversion between the low-power consumption state and the wake-up state. Optionally, the method further comprises exiting the second power saving state when any ONU exits the first power saving state. When the ONU exits the first energy saving state, the OLT also needs to exit the second energy saving state so as to ensure that the ONU exiting the first energy saving state can work normally. Optionally, the condition that the OLT exits the second energy-saving state includes any one of receiving, in an awake state, a sleep request awake message sent by any one ONU, where the sleep request awake message is used to instruct the ONU to exit the first energy-saving state, detecting, in the awake state, a local wake-up indication (LWI), detecting, in a low power consumption state, an optical signal sent by any one ONU, and detecting, in the low power consumption state, the LWI by the OLT. Optionally, the modules that the OLT shuts down in the low power state include one or more of a receiver of the optical module, a transmitter of the optical module, a serial-to-parallel converter, a media access control (medium access control, MAC) module, or a dynamic bandwidth allocation (DYNAMICALLY BANDWIDTH ASSIGNMENT, DBA) module under some or all of the channels of the OLT's target port. When the method is realized, the energy-saving requirement of the OLT and the time required by the OLT to switch from the low-power-consu
