With the continuous development of 5G technology, the number of 5G base stations is increased. Since the power consumption of the radio frequency part of the 5G base station is 3 to 4 times of that of the radio frequency part of the 4G base station, it is necessary to perform effective energy-saving control on the power consumption of the 5G base station. The existing power saving means of the base station are from time slot turn-off in the 2G era, carrier turn-off to symbol turn-off in the 4G era, channel turn-off and even cell turn-off, all of which are base station-oriented logic objects such as time slot, symbol, channel, cell and the like, the power saving efficiency is generally low, and the power consumption of the base station is still high.
In order to solve the technical problem, 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 determines the power supply condition of the output voltage control equipment of the dry contact interface according to the control instruction by using the baseband processing unit, so that the base station energy-saving efficiency is improved, and the power consumption of the base station is effectively reduced.
Fig. 1 is a first structural schematic 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 loops 302, each power supply loop 302 includes a power switch 3021, a device 3022, and a power supply 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 loop 302 through M dry contact interfaces, 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 command 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 configured to control the power supply of the device to be controlled according to the output voltage.
For example, base station identifiers of all base stations to be controlled and identifiers of all power supply loops included in each base station are prestored in the server 10. The server 10 receives the performance parameters sent by all the base stations to be controlled, determines the power supply loop and the 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 loop and the base station identifier to which the equipment to be controlled belongs. The control command may include the identifiers of a plurality of base stations to be controlled. Specifically, if the control command includes the identifiers of a plurality of base stations to be controlled, the wireless operation and maintenance center 20 forwards the control command to the baseband processing units 301 of all the base stations to be controlled. The baseband processing unit 301 analyzes 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 may be used to 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 command 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 at a low level, the relay switch is turned off, and the power supply in the power supply loop stops supplying power to the device 3022. Accordingly, when the voltage parameter in the control command is a high level voltage, the relay switch is closed, and the power supply in the power supply loop starts supplying power to the device 3022.
It can be known from the above embodiments that the setting server generates the control instruction according to the performance data sent by the N base stations, the wireless operation maintenance center forwards the control instruction to the baseband processing unit of the base station to be controlled, and the baseband processing unit determines the power supply condition of the output voltage control device of the dry contact interface according to the control instruction, thereby improving the energy saving efficiency of the base station and effectively reducing the power consumption of the base station.
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, based on the base station energy saving control system provided in fig. 1, for example, in the 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 room air conditioner 402 and an air conditioner power supply 403, and the second power supply loop includes a second power switch 501, an active antenna processing unit 502, a radio remote unit 503 and a power supply 504, where the baseband processing unit 301 is connected to the first power switch 401 through the first dry contact interface, and the baseband processing unit 301 is connected to 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 important devices for power consumption 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 accounts for more than ninety percent of the power consumption of the base station. In the embodiment of the present invention, each base station 30 is configured to include 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 room air conditioner 402, and an air conditioner power supply 403, and the second power supply loop 50 includes a second power switch 501, an active antenna processing unit 502, a radio remote unit 503, and a power supply 504. Illustratively, the performance data includes a first parameter, a second parameter, and a third parameter, where the first parameter is a temperature of a machine room of the base station 30, the second parameter is a number of users of radio resource control connections accessed to the base station within a preset time period, and the third parameter is uplink and downlink data traffic of the base station within the preset time period.
In a 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, an energy-saving control instruction is generated, 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 that the output voltage of the first dry contact interface is a low-level voltage according to the first power supply loop identifier and the low-level parameter, and the first power switch 401 is configured to turn off the air conditioner power supply 403 of the machine room air conditioner 402 according to the low-level voltage.
Illustratively, 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 temperature in the machine room is not high at present, and the machine room air conditioner 402 does not need to be turned on for cooling, the server 10 generates an energy-saving control instruction for turning off 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 temperature in the machine room is too high at present, and the machine room air conditioner 402 needs to be turned on for cooling urgently, the server 10 generates a turn-on control instruction, and turns on the air conditioner power supply 403 of the machine room air conditioner 402.
In a 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 server generates an energy-saving control instruction, 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 contact 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 radio remote unit 503 according to the low level voltage.
For example, 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 traffic threshold, it indicates that the number of users served by the current base station 30 is less, and if the current base station 30 is turned off, the influence on the users is less. 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, and the purpose of energy saving is achieved.
In a possible implementation manner, if it is determined that the second parameter of the peripheral base station of the powered-off base station 30 is less than or equal to the preset user number threshold, or the third parameter is greater than the preset flow threshold, the server 10 generates an energization control instruction, where the energization control instruction includes a base station identifier to be energized, a second power supply loop identifier, and a high level parameter, where a distance between the peripheral base station and the powered-off base station 30 is less than or equal to a preset distance, and the base station identifier to be energized is the same as the identifier of the powered-off base station; the wireless operation maintenance center 20 forwards the power-on control command 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 that an output voltage of the second dry contact interface is a high level voltage according to the second power supply loop identifier and the high level parameter, 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, and the power supply 504 supplies power to the active antenna processing unit 502 and the remote radio unit 503.
Illustratively, after the power of the active antenna processing unit 502 and the remote radio unit 503 of the base station 30 is turned off, the server 10 cannot receive the performance data of the base station any more. In order to avoid the influence on the user experience caused by the long-time closing of the base station, the server 10 determines when to open the base station again according to the performance data of the base stations around the closed base station. Specifically, all base stations with a distance from the powered-off base station being less than or equal to a preset distance are taken as peripheral base stations of the base station, and when the server 10 determines that the second parameter of any peripheral base station is less than or equal to a preset user number threshold or the third parameter is greater than a preset flow threshold, it indicates that the load of the peripheral base station is high, and the base station needs to be opened in time to provide data access service for the user. The server 10 generates an energization control instruction, and the wireless operation maintenance center 20 forwards the energization control instruction to the baseband processing unit 301 of the base station to be energized according to the identifier of the base station to be energized; the baseband processing unit 301 determines that the output voltage of the second dry contact interface is a high level voltage according to the second power supply loop identifier and the high level parameter, and the second power switch 501 is configured to turn on the active antenna processing unit 502 and the power supply 504 of the remote radio unit 503 according to the high level voltage.

Specifically, the power switch is a relay switch. After the relay switch is connected, the output high level of the dry contact interface is less 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 relay switch can be controlled according to the boosted voltage.
