While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
Referring to fig. 1, there is shown a block diagram of a first embodiment of an energy saving control system according to the present invention, the system comprising: a low power processor 101 and an RRU102, where the low power processor 101 is in communication connection with the RRU102, and the RRU102 at least includes: a digital control unit 1021, an optical module 1022 and a power supply unit 1023, wherein the power supply unit 1023 supplies power to the optical module 1022 and the low power consumption processor 101 through a first circuit 103, and supplies power to other components in the RRU except for the optical module 1022 through a second circuit 104, and the low power consumption processor 101 comprises:
an energy saving start information receiving module 1011, configured to receive the energy saving start information sent by the digital control unit 1021.
The low-power processor is a processor with simple processing capability and low power consumption, such as a common single chip microcomputer. The embodiment of the invention does not limit the specific model of the low-power processor. In the embodiment of the present invention, the low power consumption processor may be integrated on the RRU or may be independent of the RRU.
And the RRU converts the baseband optical signals into radio frequency signals at a far end, amplifies the radio frequency signals and transmits the radio frequency signals.
The digital control unit is used for controlling cooperation and response of each unit in the RRU, and is usually a multi-core processor which comprises a peripheral circuit, so that the power consumption of the digital control unit is higher than that of a low-power processor by multiple orders of magnitude. The energy saving start information may be an electrical signal from the digital control unit to the processor with low power consumption, and the digital control unit and the processor with low power consumption are connected through an interface (e.g., a serial port).
The optical module can receive and transmit an optical signal and transmit energy-saving start information to the digital control unit when receiving the energy-saving start information in the form of the optical signal.
The power supply unit is used for supplying power to each unit in the RRU, and in the embodiment of the present invention, power needs to be supplied to a newly added low power consumption processor.
The second circuit is respectively connected with the power supply unit, the transceiver, the power amplifier, the digital intermediate frequency unit, the clock unit, the low noise amplifier, the antenna, the digital control unit and the digital interface unit.
A power saving processing module 1012, configured to control the power supply unit 1023 to switch off the second circuit 104 after a preset first time period, and keep the first circuit 103 in an on state.
The first time period is used for providing a certain response delay, ensuring that each unit in the RRU receives the energy-saving starting information, and making energy-saving starting preparation. It is understood that the first time period may be set according to an actual application scenario, which is not limited in the embodiment of the present invention, and of course, the first time period is generally a time value with an extremely small order of magnitude, and may be accurate to nanoseconds, so as to provide better accuracy.
After the second circuit is cut off, other components (such as a transceiver, a power amplifier, a digital intermediate frequency unit, a clock unit, a low noise amplifier, an antenna, a digital control unit and a digital interface unit) except the optical module and the low power consumption processor are powered off, and the operation is stopped; and because the first circuit keeps the opening state, the optical module and the low-power processor are both in the power supply state and continue to work.
Since the power consumption of the low power consumption processor is much smaller than that of the digital control unit, it contributes to a reduction in power consumption compared to when the digital control unit is in a power supply state.
An embodiment of the present invention provides an energy saving control system, where the system includes: the RRU comprises a low-power processor and an RRU, wherein the low-power processor is in communication connection with the RRU, and the RRU at least comprises: the RRU comprises a digital control unit, an optical module and a power supply unit, wherein the power supply unit supplies power to the optical module and a low-power processor through a first circuit respectively, and supplies power to other components except the optical module in the RRU through a second circuit, and the low-power processor comprises: the energy-saving starting information receiving module is used for receiving the energy-saving starting information sent by the digital control unit; and the energy-saving processing module is used for controlling the power supply unit to cut off the second circuit after a first time period is preset and keeping the first circuit in an open state. When the RRU does not work, all parts including the digital control unit and the digital interface unit are powered off, and the low-power processor and the optical module are kept in a power supply state.
Example two
Referring to fig. 2, a block diagram of an embodiment of an energy saving control system according to the invention is shown, the system includes: the system comprises a low-power processor 201, an RRU202 and a BBU205, wherein the low-power processor 201 is in communication connection with the RRU202, the optical module is in communication connection with the BBU, and the RRU202 at least comprises: a digital control unit 2021, a light module 2022 and a power supply unit 2023, wherein the power supply unit 2023 supplies power to the light module 2022 and the low power consumption processor 201 through a first circuit 203, respectively, and supplies power to other components in the RRU except the light module 2022 through a second circuit 204, and the low power consumption processor 201 includes:
an energy saving start information receiving module 2011, configured to receive the energy saving start information sent by the digital control unit 2021.
The module may refer to the detailed description of the power saving activation information receiving module 3011, and is not described herein again.
The energy saving processing module 2012 is configured to control the power supply unit 2023 to switch off the second circuit 204 after a preset first time period, and keep the first circuit 203 in an on state.
The module can refer to the detailed description of the energy saving processing module 3012, and is not described here again.
An electrical signal monitoring module 2013, configured to monitor an electrical signal sent by the optical module 2022.
In practical application, the BBU is also a decision maker for recovering power supply, and after the BBU decides to recover power supply, an optical signal is sent to an optical module in the RRU through an optical module in the BBU, so that the output level of the optical module in the RRU changes; otherwise, the BBU does not send optical signals to the RRU all the time and keeps the power-off state all the time.
In the embodiment of the present invention, after each unit in the RRU is powered off, the low power consumption processor needs to monitor the electrical signal from the optical module in the RRU, and determine whether the electrical signal has a preset change, where the preset change represents that power supply is restored.
The preset change may be that the level changes from high to low or from low to high. It can be understood that the change direction and the change amount can be set according to an actual application scenario and a circuit implementation of the optical module in the RRU, which is not limited in the embodiment of the present invention. For example, when a circuit of the optical module in the RRU outputs a low level when the optical module does not receive an optical signal, and outputs a high level when the optical module receives the optical signal, the preset change may be set to be a jump from the low level to the high level.
And a recovery control module 2014, configured to determine whether to control the RRU202 to recover the operating state according to the electrical signal.
Specifically, the direction and the amount of transition of the electrical signal may be determined.

It can be understood that the operation recovery information is used to indicate that each unit in the RRU is powered on and can operate normally. The job restoration information is an optical signal.
The embodiment of the invention can inform the BBU after the RRU recovers work, and is beneficial to ensuring the communication quality between the BBU and the RRU.
The digital control unit 2021 further includes:
a first optical signal stop sending subunit 20211, configured to receive the energy saving start information sent by the BBU205, and control the optical module to stop sending the first optical signal to the BBU205 after a preset second time period, where the second time period is less than the first time period.
The BBU (Building base band Unit, indoor Baseband processing Unit) is installed indoors, and performs Baseband processing functions (e.g., encoding, multiplexing, modulating, and spreading) of a Uu interface, Iub interface functions, signaling processing, local and remote operation and maintenance functions of an RNC (Radio Network Controller), and a working state monitoring and alarm information reporting function of a NodeB system. The BBU and the RRU are connected through optical fibers, and optical modules are arranged in the BBU and the RRU, so that optical signals are transmitted.
In the embodiment of the invention, the decision maker for energy saving is also the BBU, and after deciding energy saving, the BBU sends the energy saving start information to the optical module in the RRU through the optical module in the BBU.
The second time period may be set according to an actual application scenario, which is not limited in the embodiment of the present invention.
The first optical signal is an optical signal sent by the RRU to the BBU and is used for carrying communication information from the RRU to the BBU. In the embodiment of the invention, in the energy-saving mode, the optical module in the RRU stops sending the first optical signal to the optical module in the BBU, so that the electric quantity consumed by sending the optical signal can be saved, and further energy saving is facilitated.
It will be appreciated that the second time period being less than the first time period may ensure that: the second circuit is switched prior to the time when the first optical signal is stopped being transmitted.
The BBU205 further includes:
a second optical signal sending stop sub-unit 2051, configured to stop sending the second optical signal to the RRU202 when the first optical signal is not received within a preset third time period.
The third time period may be set according to the normal transmission time of the first optical signal in the actual application scenario, which is not limited in the embodiment of the present invention. It is understood that the third time period is greater than the second time period.
The second optical signal is an optical signal sent by the BBU to the RRU and carries communication information from the BBU to the RRU. In the embodiment of the invention, the optical module in the BBU stops sending the second optical signal to the optical module in the RRU in the energy-saving mode, so that the electric quantity consumed by sending the optical signal can be saved, and further energy saving is facilitated.
Optionally, in another embodiment of the present invention, the recovery control module 2014 includes:
and the level jump determining submodule is used for determining whether the electrical signal has level jump or not.
Wherein the level hopping includes: jump from low level to high level and jump from high level to low level.
And the second circuit starting submodule is used for controlling the power supply unit to start the second circuit under the condition that the electrical signal has level jump.
It can be understood that after the second circuit is turned on, the power supply to the power supply unit and the transceiver, the power amplifier, the digital intermediate frequency unit, the clock unit, the low noise amplifier, the antenna, the digital control unit, and the digital interface unit is restored, and each unit in the RRU can operate normally.
In addition, under the condition that the electrical signal has no level jump, the second circuit is not started, and all units in the RRU are kept in a power-down state.
