Description

CROSS-REFERENCE TO RELATED APPLICATION The present disclosure is a national stage filing under 35 U.S.C. § 371 of international application number PCT/CN2022/098374, filed Jun. 13, 2022, which claims the priority to Chinese patent application no. CN 202110725871.X filed on Jun. 29, 2021, the disclosure of which is incorporated herein by reference in its entirety. TECHNICAL FIELD Examples of the disclosure relate to the field of terminal devices, and in particular to a method and apparatus for controlling power consumption of an optical network unit (ONU). BACKGROUND With an optical network constantly developed, an optical network unit (ONU), a terminal product, has also been used in a wide range in line with widespread popularization of fiber to the home (FTTH). With ongoing development of a passive optical network (PON) technology and growing demand of users for products, increasing functions of the ONU are fulfilled. For example, a smart home gateway device typically requires multi-core processing and supports Wireless Fidelity (WiFi) 5 or wifi6, a first generation mobile communication (1 G)/2.5 G/10 G network port, a Universal Serial Bus (USB), voices, etc., resulting in a constant increase in power consumption. Generally, the smart home gateway device's power consumption is 6 W or more in a full load running state, and remains high in a standby state without effective power consumption reduction measures. Operators at home and abroad focus on power consumption of the ONU. China Mobile and China Unicom have set out power consumption test requirements for different scenarios, such as a power consumption capacity in the case of running all services and a power consumption capacity in the case of stopping all services. The European Union divides the ONU into an off-state, an idle-state, and an on-state. Different power consumption levels must be reached in different states. Different operators have different requirements for power consumption of the ONU. The energy saving requirement is also defined in the PON standard. In a passive optical network system, energy saving support capacities in different PON modes vary. In the PON standard, energy saving interrupt and energy saving state machine skipping methods corresponding to different energy saving modes are defined, but no particular solutions have been provided yet. Therefore, no particular energy saving solution in different energy saving states have been provided in the related art, and there is no way to reduce running power consumption of the ONU effectively. SUMMARY Examples of the disclosure provide a method and apparatus for controlling power consumption of an optical network unit (ONU), an electronic device, and a storage medium, so as to effectively reduce running power consumption of the ONU and realize energy saving and emission reduction of an operator network communication system. In order to solve the above technical problems, a method for controlling power consumption of an ONU is provided in an example of the disclosure. The method includes: monitoring a current state of the ONU in real time, where the current state at least includes a deep energy saving state, and data flow of the ONU in the deep energy saving state is lower than a preset threshold; and performing message processing on received data through a central processing unit (CPU) channel and performing a power-off operation on a hardware module in an acceleration channel of the ONU when the ONU is currently in the deep energy saving state; where the acceleration channel is connected to a data ingress of the ONU, and the hardware module in the acceleration channel is configured to perform message processing on the received data of the ONU; and the CPU channel is a channel established between the data ingress of the ONU and a CPU and is configured to perform message processing on the received data of the ONU through the CPU. An apparatus for controlling power consumption of an ONU is further provided in an example of the disclosure. The apparatus includes: a monitoring module configured to monitor a current state of the ONU in real time, where the state at least includes a deep energy saving state, and data flow of the ONU in the deep energy saving state is lower than a preset threshold; and a processing module configured to perform message processing on received data through a CPU channel and perform a power off operation on a hardware module in an acceleration channel of the ONU when the ONU is currently in the deep energy saving state; where the acceleration channel is connected to a data ingress of the ONU, and the hardware module in the acceleration channel is configured to perform message processing on the received data of the ONU; and the CPU channel is a channel established between the data ingress of the ONU and a CPU and is configured to perform message processing on the received data of the ONU through the CPU.
