Specifically, the power control module 101 is configured to control the power module 102 to turn on and off.
It will be appreciated that the micro base station also includes a network switching module not shown in fig. 1. The network switching module is used for receiving a cell setting instruction input by a user. The network switching module includes a plurality of wired network ports for communicating with the internal modules of the micro base station. The wired network ports are connected to the power control module 101 and the baseband modules 103, respectively, so that the received cell setting command can be transmitted to the power control module 101 and the baseband modules 103 through the wired network ports.

A main controller chip (MCU for short) on the power control module 101 processes and controls data, and the control of the power module is implemented by connecting a General Purpose Input/Output (GPIO) Output on the power control module 101 to switches of a plurality of power modules. The power control module 101 further includes a network switch chip (ethernet PHY; Port Physical Layer, PHY for short).
The cell setting instruction refers to an instruction for creating, reconstructing or deleting a cell. And modifying the cell means modifying relevant parameters (such as standard and frequency point) of the cell. When a cell is reconfigured, a cell service interruption may occur.

The power module 102 supplies power (i.e., supplies power) to the baseband module 103 connected thereto or to the power amplifier module 104 connected thereto.
Each power supply module 102 is connected to the GPIO of the power supply control module 101 through a control line, and receives a control instruction sent by the power supply control module 101. The control command is a command for turning on or off the power module 102.

According to the cell setting instruction, each baseband module 103 can drive and control the corresponding power amplifier module 104 to work, so as to implement new establishment, reconstruction or deletion of the cell.

The information of the baseband module and the power amplifier module comprises the information of the baseband module and the power amplifier module corresponding to the current pre-established system and the frequency point cell. The cell setting instruction carries information of a current pre-established system and a frequency point cell; according to the mode and the frequency point of the current pre-established cell, the information of the baseband module and the power amplifier module corresponding to the current pre-established mode and the frequency point cell can be obtained. And the current pre-established standard and frequency point cell refers to a current pre-established cell generated according to the standard and the frequency point.

The power module corresponding to the information of the baseband module and the power amplifier module refers to the power module which needs to change states and is determined according to the information of the baseband module and the power amplifier module. The state of the power module includes on and off.
For example, a cell C1 is established by the baseband module a1 and the power amplifier module B1, if the cell setting instruction is to newly establish a cell C2, the power control module analyzes the cell setting instruction to determine that the carried information of the baseband module and the power amplifier module is the baseband module a1 and the power amplifier module B2, and since the state of the power module connected to the baseband module a1 is on and does not need to be modified, the corresponding power module is the power module connected to the power amplifier module B2 (the power module connected to B1 is different from the power module connected to B2), the power module connected to the power amplifier module B2 is turned on; if the cell setting instruction is a newly-built cell C3, the power control module analyzes the cell setting instruction to determine that the carried information of the baseband module and the power amplifier module is baseband module a2 and power amplifier module B3, so that the corresponding power modules are the power module connected to baseband module a2 and the power module connected to power amplifier module B3 (the power modules connected to B1 and B3 are different), and the two power modules are turned on.
According to the embodiment of the invention, the power control module analyzes the cell setting instruction, the corresponding power module is turned on or off, the power module can be turned on or off according to the requirement of a user, but not all the power modules are always in the power-on state, the power consumption in unit time can be reduced, the uninterrupted working time of the micro base station at one time can be prolonged, the service life of each module in the micro base station can be prolonged, and the waste of electric energy and the endurance time of the micro base station can be reduced. Furthermore, through the control of the intelligent mobile terminal, the power supply operation and the state monitoring of the whole micro base station can be intelligentized and visualized, and the user experience is improved.

the storage battery module is used for providing electric energy for the plurality of power supply modules;
correspondingly, the power supply control module is also used for controlling the rotating speed of the fan according to the load of the micro base station.
Specifically, the battery module is connected to each power module 102, and supplies electric power to each power module 102.
It can be understood that, because the output voltage of the storage battery module may be different from the working voltage of the baseband module 103 or the working voltage of the power amplifier module 104, the input voltage of the power supply module is the output voltage of the storage battery module, and the output voltage is the working voltage of the baseband module 103 or the power amplifier module 104 connected thereto, so as to implement the voltage transformation function.
It can be understood that, since each module of the micro base station generates heat during operation, a cooling fan (fan for short) is required to cool down. The rotational speed of the fan may be adjustable, i.e. the rotational speed of the fan may be adjustable.
The power control module is connected with the fan through a control line.
It is understood that the micro base station further includes a power module for supplying power to the power control module and a power module for supplying power to the fan. The power supply module which supplies power to the power supply control module is connected with the storage battery module, and the storage battery module supplies power to the storage battery module. And the power supply module is used for supplying electric energy to the fan and is connected with the storage battery module, and the storage battery module supplies electric energy to the power supply module.

By controlling the power on and off, the baseband module and the power amplifier module in the working state are changed, and after the power module corresponding to the information of the baseband module and the power amplifier module is turned on or turned off, the power control module 101 recalculates the load of the micro base station and controls the rotating speed of the fan according to the new load of the micro base station obtained by recalculation. The power control module 101 recalculates the load of the micro base station, which is the power consumption of the baseband module and the power amplifier module corresponding to the current pre-established system and the frequency point cell.
Comparing the new load of the micro base station obtained by recalculation with the load of the micro base station before the power module corresponding to the information of the starting or closing baseband module and power amplifier module, and if the load is increased, increasing the rotating speed of the fan; if the load is reduced, the rotating speed of the fan can be reduced; the specific variation of the rotation speed of the fan may be determined according to a preset rotation speed control algorithm.
The embodiment of the invention adjusts the rotating speed of the fan according to the load of the micro base station, and can prevent the fan from always running at full speed, thereby reducing the waste of electric energy and prolonging the endurance time of the storage battery.
Based on the content of the foregoing embodiments, the micro base station further includes: a temperature sensor; the temperature sensor is used for acquiring the temperature at the heat dissipation air outlet of the micro base station;
correspondingly, the power control module is also used for controlling the rotating speed of the fan according to the temperature at the heat dissipation air outlet.
Specifically, the rotation speed of the fan may be adjusted according to the temperature at the heat radiation outlet of the micro base station, in addition to the rotation speed of the fan adjusted according to the load of the micro base station.
The temperature at the heat dissipation air outlet of the micro base station is acquired through a temperature sensor. After the power module corresponding to the information of the baseband module and the power amplifier module is turned on or turned off, the temperature at the heat dissipation air outlet may change. The temperature change comes from two aspects: firstly, the cell standard frequency point is not changed, and the transmitting power is manually adjusted; and the other is the temperature change of the working environment where the whole micro base station is located.
If the temperature at the radiating air outlet rises after the power supply module corresponding to the information of the baseband module and the power amplifier module is turned on or turned off, the rotating speed of the fan can be increased; if the temperature is reduced, the rotating speed of the fan can be reduced, and the power supply is saved to the maximum extent under the condition of ensuring good heat dissipation of the whole machine; the specific variation of the rotation speed of the fan may be determined according to a preset rotation speed control algorithm.
According to the embodiment of the invention, the rotating speed of the fan is adjusted according to the temperature at the radiating air outlet, so that the fan can be prevented from always running at full speed, the waste of electric energy can be reduced, and the endurance time of the storage battery can be prolonged.
