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) system. In case the optical line terminal (opticallineterminal, OLT) allows the optical network unit (opticalnetworkunit, 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, since the time at which each ONU enters the power saving state is different, the duration of the awake state and the duration of the low power consumption state may also be different, and thus the power saving states of the respective ONUs are unsynchronized. Disclosure of Invention The application provides a control method, a device, equipment, a system and a medium for an energy-saving state, which can realize the synchronization of the energy-saving states of a plurality of slave devices. 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 master device is connected to a plurality of slave devices through optical fibers. The control method of the energy-saving state comprises the steps that a master device determines that at least two slave devices in the energy-saving state exist in the plurality of slave devices, and energy-saving indication information is sent to the at least two slave devices in the energy-saving state, wherein the energy-saving indication information is used for indicating the slave devices to set the energy-saving state based on energy-saving configuration information, and the energy-saving configuration information comprises duration of a sleep state and duration of a wake-up state. After the plurality of slave devices receive the energy-saving indication message, the energy-saving state is set based on the energy-saving configuration information, so that the synchronization of the energy-saving states of the plurality of slave devices can be realized. That is, the present application can achieve synchronization of the power saving state of at least part of the slave devices connected to the master device. Here, synchronization of the power saving states of the plurality of slave devices means that the plurality of slave devices simultaneously enter the power saving state, simultaneously enter the sleep state from the awake state, and simultaneously transition from the sleep state to the awake state. Optionally, the power saving state of the slave device includes a sleep state, a sleep awake state, a doze state, and a doze awake state. The slave device is in a sleep state and a doze state, at least part of the modules of the slave device are turned off to reduce the power consumption of the slave device. The sleeping state and the dozing state have the same duration, and the sleeping wake-up state and the dozing wake-up state have the same duration. When the slave device is in the sleep state and the doze state, the master device needs to store downlink data of the slave device, and the downlink data is sent to the slave device after the slave device enters the sleep awake state or the doze awake state. Therefore, when the sleep state is long and the energy-saving states of the slave devices are not synchronous, if the downlink data of the plurality of slave devices need to be queued for transmission, the slave devices corresponding to the downlink data received first may be in the sleep state or the doze state, so that the downlink data received later cannot be transmitted to the corresponding slave devices. The downlink data transmission of the plurality of slave devices is blocked, so that the data amount required to be stored by the master device is larger, and the storage capacity requirement of the master device is higher. By synchronizing the energy-saving states of the slave devices, the application can send out the downlink data of each slave device in the wake-up state, thereby avoiding the situation of downlink data blocking and further reducing the requirement on the storage capacity of the master device. Optionally, the energy saving indication message is a sleep permission message. The energy-sav
