All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
With the continuous development of 5G technology, the number of 5G base stations increases. Because the power consumption of the radio frequency part of the 5G base station is 3 to 4 times that of the radio frequency part of the 4G base station, it is highly desirable to effectively control the power consumption of the 5G base station. The existing base station electricity-saving means are logic objects facing to the base station such as time slots, symbols, channels, cells and the like from time slot turn-off of the 2G age, carrier turn-off to symbol turn-off of the 4G age, channel turn-off and even cell turn-off, and the electricity-saving efficiency is generally low, and the electricity consumption of the base station is still high.
In order to solve the technical problems, according to the base station energy-saving control system provided by the invention, the server generates the control instruction according to the performance data sent by the N base stations, forwards the control instruction to the baseband processing unit of the base station to be controlled through the wireless operation maintenance center, and improves the energy-saving efficiency of the base station and effectively reduces the power consumption of the base station by determining the power supply condition of the output voltage control equipment of the dry contact interface according to the control instruction through the baseband processing unit.
Fig. 1 is a schematic structural diagram of a base station energy-saving control system according to an embodiment of the present invention. As shown in fig. 1, the base station energy saving control system provided in the embodiment of the present invention includes a server 10, a wireless operation and maintenance center 20, and N base stations 30, where each base station 30 includes a baseband processing unit 301 and M power supply circuits 302, each power supply circuit 302 includes a power switch 3021, an apparatus 3022, and a power source 3023, the server 10 is connected to the wireless operation and maintenance center 20, the wireless operation and maintenance center 20 is connected to the baseband processing unit 301 of each base station 30, and the baseband processing unit 301 is connected to the power switch 3021 of each power supply circuit 302 through M dry interface, where N and M are positive integers.
In the embodiment of the present invention, the server 10 generates a control instruction according to the performance data sent by the N base stations 30, and sends the control instruction to the wireless operation maintenance center 20, where the control instruction includes a base station identifier to be controlled, a power supply loop identifier to be controlled, and a voltage parameter; the wireless operation maintenance center 20 forwards the control instruction to the baseband processing unit 301 of the base station to be controlled according to the base station identifier to be controlled; the baseband processing unit 301 controls the output voltage of the dry contact interface according to the power supply loop identifier to be controlled and the voltage parameter, and the power switch 3021 is used for controlling the power supply of the device to be controlled according to the output voltage.
Illustratively, the base station identities of all the base stations to be controlled, and the identities of all the power supply loops included in each base station are pre-stored in the server 10. The server 10 receives performance parameters sent by all the base stations to be controlled, determines a power supply loop and a base station identifier to which the equipment to be controlled belongs by analyzing the performance parameters, and generates a control instruction according to the power supply loops and the base station identifier to which the equipment to be controlled belongs. The control instruction may include identifiers of a plurality of base stations to be controlled. Specifically, if the control instruction includes the identifiers of the plurality of base stations to be controlled, the wireless operation maintenance center 20 forwards the control instruction to the baseband processing units 301 of all the base stations to be controlled. The baseband processing unit 301 parses the control instruction, and determines a power supply loop identifier and a voltage parameter corresponding to the current base station identifier, so that the baseband processing unit 301 controls the output voltage of the dry contact interface according to the power supply loop identifier and the voltage parameter to be controlled. Specifically, the control instruction may be used to turn off the power switch 3021 in the power supply circuit, or turn on the power switch 3021 in the power supply circuit. Illustratively, the power switch 3021 is a relay switch, and when the voltage parameter in the control instruction is a low level voltage, the baseband processing unit 301 controls the output voltage of the dry contact interface to be a low level. When the voltage applied to the relay switch is low, the relay switch is turned off, and the power supply in the power supply circuit stops supplying power to the apparatus 3022.

According to the embodiment, the control instruction is generated by the setting server according to the performance data sent by the N base stations, the control instruction is forwarded to the baseband processing unit of the base station to be controlled by the wireless operation maintenance center, and the power supply condition of the output voltage control equipment of the dry contact interface is determined by the baseband processing unit according to the control instruction, so that the energy saving efficiency of the base station is improved, and the electricity consumption of the base station is effectively reduced.
Fig. 2 is a schematic structural diagram of a base station energy-saving control system according to an embodiment of the present invention. As shown in fig. 2, in the base station energy-saving control system provided in fig. 1, in an exemplary base station energy-saving control system provided in the embodiment of the present invention, M power supply loops 302 include a first power supply loop 40 and a second power supply loop 50, M dry contact interfaces include a first dry contact interface and a second dry contact interface, the first power supply loop includes a first power switch 401, a machine room air conditioner 402 and an air conditioner power supply 403, the second power supply loop includes a second power switch 501, an active antenna processing unit 502, a remote radio unit 503 and a power supply 504, where the baseband processing unit 301 is connected with the first power switch 401 through the first dry contact interface, and the baseband processing unit 301 is connected with the second power switch 501 through the second dry contact interface.
The machine room air conditioner 402, the active antenna processing unit 502 and the remote radio unit 503 are the most main power consumption devices of the base station, and the total power consumption of the machine room air conditioner 402, the active antenna processing unit 502 and the remote radio unit 503 is more than ninety percent of the power consumption of the base station. In the embodiment of the present invention, by setting that each base station 30 includes a first power supply loop 40 and a second power supply loop 50, where the first power supply loop 40 includes a first power switch 401, a machine room air conditioner 402 and an air conditioner power supply 403, the second power supply loop 50 includes a second power switch 501, an active antenna processing unit 502, a remote radio unit 503 and a power supply 504. The performance data includes a first parameter, a second parameter, and a third parameter, where the first parameter is a room temperature of the base station 30, the second parameter is a number of radio resource control connection users accessing the base station in a preset time period, and the third parameter is an uplink and downlink data traffic of the base station in the preset time period.
In one possible implementation manner, if the server 10 determines that the first parameter of the base station 30 is less than or equal to the preset temperature threshold, the server generates an energy-saving control instruction, where the energy-saving control instruction includes a base station identifier to be powered off, a first power supply loop identifier, and a low level parameter; the wireless operation maintenance center 20 forwards the energy-saving control instruction to the base station 30 to be powered off according to the base station identifier to be powered off; the baseband processing unit 301 determines, according to the first power supply loop identifier and the low level parameter, that the output voltage of the first dry interface is a low level voltage, and the first power switch 401 is configured to turn off the air conditioning power supply 403 of the machine room air conditioner 402 according to the low level voltage.
For example, when the server 10 determines that the temperature in the machine room is less than or equal to the preset temperature threshold, it indicates that the current temperature in the machine room is not high, the server 10 generates an energy-saving control instruction for turning off the machine room air conditioner 402 without turning on the machine room air conditioner 402, and when the server 10 determines that the temperature in the machine room is higher than the upper limit value of the temperature, it indicates that the current temperature in the machine room is too high, it is urgently required to turn on the machine room air conditioner 402 to cool, the server 10 generates an on control instruction, and turns on the air conditioner power supply 403 of the machine room air conditioner 402.
In one possible implementation manner, if the server 10 determines that the second parameter of the base station 30 is less than or equal to the preset user number threshold and the third parameter is less than or equal to the preset flow threshold, the energy-saving control instruction is generated, where the energy-saving control instruction includes a base station identifier to be powered off, a second power supply loop identifier, and a low level parameter; the wireless operation maintenance center 20 forwards the energy-saving control instruction to the base station 30 to be powered off according to the base station identifier to be powered off; the baseband processing unit 301 is configured to determine, according to the second power supply loop identifier and the low level parameter, that the output voltage of the second dry interface is a low level voltage, and the second power switch 501 is configured to turn off the power supply 504 of the active antenna processing unit 502 and the remote radio unit 503 according to the low level voltage.
For example, if the second parameter of the base station 30 is less than or equal to the preset number of users threshold and the third parameter is less than or equal to the preset traffic threshold, the server 10 indicates that the number of users served by the current base station 30 is smaller, and if the current base station 30 is turned off, the influence on the users is smaller. Therefore, the power consumption of the base station 30 can be reduced by turning off the power supply 504 of the active antenna processing unit 502 and the remote radio unit 503 of the current base station 30, so as to achieve the purpose of energy saving.
In one possible implementation manner, if the server 10 determines that the second parameter of the peripheral base stations of the powered-off base station 30 is less than or equal to the preset user quantity threshold, or the third parameter is greater than the preset flow threshold, then generating a power-on control instruction, where the power-on control instruction includes a base station identifier to be powered on, a second power supply loop identifier, and a high level parameter, where a distance between the peripheral base stations and the powered-off base station 30 is less than or equal to the preset distance, and the identifier of the base station to be powered on is the same as the identifier of the powered-off base station; the wireless operation maintenance center 20 forwards the power-on control instruction to the baseband processing unit 301 of the base station to be powered on according to the base station identifier to be powered on; the baseband processing unit 301 is configured to determine, according to the second power supply loop identifier and the high level parameter, that the output voltage of the second dry interface is a high level voltage, and the second power switch 501 is configured to turn on the power supply 504 of the second power supply loop 50 according to the low level voltage, where the power supply 504 supplies power to the active antenna processing unit 502 and the remote radio unit 503.
Illustratively, after powering off the active antenna processing unit 502 and the remote radio unit 503 of the base station 30, the server 10 is no longer able to receive performance data of the base station. To avoid that the base station is turned off for a long time, which affects the user experience, the server 10 decides when to turn on the base station again according to the performance data of the base stations around the turned-off base station. Specifically, all base stations with the distance smaller than or equal to the preset distance from the powered-off base station are used as the peripheral base stations of the base station, and when the server 10 determines that the second parameter of any peripheral base station is smaller than or equal to the preset user quantity threshold value or the third parameter is larger than the preset flow threshold value, the load of the peripheral base stations is higher, and the base stations need to be opened in time to provide data access service for users. The server 10 generates an energizing control instruction, and the wireless operation maintenance center 20 forwards the energizing control instruction to the baseband processing unit 301 of the base station to be energized according to the base station identifier to be energized; the baseband processing unit 301 determines, according to the second power supply loop identifier and the high level parameter, that the output voltage of the second dry interface is a high level voltage, and the second power switch 501 is configured to turn on the power supply 504 of the active antenna processing unit 502 and the remote radio unit 503 according to the high level voltage.
According to the embodiment, the power supplies of the machine room air conditioner and the active antenna processing unit with higher power consumption and the remote radio unit in the base station are precisely controlled, so that the energy-saving efficiency of the base station is improved to the maximum extent and the power consumption of the base station is effectively reduced under the condition that the temperature control effect of the machine room is not affected and the service experience of a user is not affected.

Specifically, the power switch is a relay switch. After the relay switch is connected, the output high level of the dry contact interface is smaller than 3V, the control requirement of the relay switch cannot be met, the output voltage of the dry contact interface can be boosted through the voltage controller, and the control of the relay switch is realized according to the boosted voltage.
