As shown in FIG. 1 , a second embodiment of the present invention provides a method for monitoring power consumption of a base station, including: Step 11: The power consumption unit of the base station is divided into power consumption groups according to changes in power consumption thereof, and the power consumption group includes a first power consumption group composed of power consumption units with stable power consumption, and power consumption changed by power consumption law The second power consumption group formed by the unit is a third power consumption group composed of power consumption units whose power consumption changes irregularly.

Specifically, the foregoing step 11 may include: hierarchically dividing the base station into the smallest power consumption unit, determining whether the power consumption of each of the minimum power consumption units is affected by the environment, the service, and the like, and the relationship between the power consumption change and the environment, the service, and the like. And dividing the power consumption unit into the first power consumption group, the second power consumption group, or the third power consumption group.

Exemplarily, as shown in FIG. 2, taking an indoor macro base station as an example, the base station is hierarchically divided into minimum power consumption units:

The first layer: carrier frequency cabinet, power cabinet.

The second layer: The carrier frequency cabinet includes: an antenna feeder unit, a carrier frequency unit, a heat dissipation unit, and a control unit. The heat dissipating unit may include a fan unit, or an air conditioning unit, or a heat exchange unit.

The third layer: The carrier unit includes: PA (Power Amplifier) unit, TRX unit, BB unit, power unit.

For example, the power consumption of the power consumption unit is basically unchanged or the change is negligible due to environmental, service, etc., that is, the power consumption of the power consumption unit is stable, and then divided into the first power consumption group. For example, the antenna feeder unit in FIG. 2, the TRX (Transmission Receiver Unit), the BB (Base Band) unit, and the like of the carrier frequency.

If the power consumption of the power consumption unit is changed by the influence of the environment, the service, etc., that is, the power consumption law of the power consumption unit changes, it is divided into the second power consumption group. Exemplarily, the heat dissipation unit of the carrier frequency as in Fig. 2, and the like.

If the power consumption of the power consumption unit is irregular due to the influence of the environment and the service, that is, the power consumption of the power consumption unit changes irregularly, it is divided into the third power consumption group. For example, the PA (Power Amplifier) unit of the carrier frequency in FIG. 2 is hereinafter referred to as a power amplifier unit.

Step 12: Determine the number of power consumption units in the first power consumption group, and obtain the power consumption value of the power consumption unit in the first power consumption group. Specifically, in the foregoing step 12, determining the number of power consumption units in the first power consumption group may include:

The number of power consumption units in the first power consumption group is determined by querying the configuration of the base station.

Since the number of hardware units based on the base station is fixed, the number of power consumption units can be obtained by querying the configuration analysis of the base station. Obtaining the power consumption value of the power consumption unit in the first power consumption group in the foregoing step 12 may include:

The power consumption value corresponding to the power consumption unit in the first power consumption group is obtained according to a pre-established database of power consumption units in the first power consumption group and the power consumption value thereof.

It can be seen that the power consumption of the power consumption unit in the first power consumption group is basically unchanged or the change is negligible due to environment, service, etc., that is, the power consumption of the power consumption unit is stable, and the power consumption unit and its power consumption value can be established in advance. Corresponding to the database of the relationship, thereby obtaining the power consumption value of the power consumption unit by querying the database.

Step 13, determining the number of power consumption units in the second power consumption group, and acquiring the power consumption value of the power consumption unit in the second power consumption group, or monitoring the first relevant parameter of the power consumption unit in the second power consumption group according to The power consumption variation law obtains the corresponding power consumption value.

Specifically, in the foregoing step 13, determining the number of power consumption units in the second power consumption group may include:

The number of power consumption units in the second power consumption group is determined by querying the configuration of the base station, and details are not described herein.

In the foregoing step 13, obtaining the power consumption value of the power consumption unit in the second power consumption group may include: The input current value and the input voltage value of the power consumption unit in the second power consumption group are monitored by the sampling circuit.

According to the input current value and voltage value obtained by the monitoring, the corresponding power consumption value is obtained.

It can be seen that by using the inherent sampling circuit, without adding special measuring instruments, without involving the transformation of the equipment room, the input current value Iin and the input voltage value Uin of the power consumption unit in the second power consumption group can be obtained, and then according to the input power Pin=Uin * Iin, which is the power consumption P of the power consumption unit.

Exemplarily, when the power consumption unit in the second power consumption group includes a heat dissipation unit, for example, the heat dissipation unit may include a fan unit, or an air conditioning unit, or a heat exchange unit, etc., by using a sampling circuit inherent to the heat dissipation unit, the heat dissipation unit is monitored. Output current value and voltage value.

Alternatively, in the foregoing step 13, the output current value and the voltage value of the power consumption unit in the second power consumption group may not be directly monitored, but the first relevant parameter of the power consumption unit in the second power consumption group may be monitored according to the power consumption. Obtaining a corresponding power consumption value according to the change rule may include: monitoring a first relevant parameter of the power consumption unit in the second power consumption group, where the first related parameter and the power consumption value conform to a power consumption variation rule. And obtaining a power consumption value corresponding to the power consumption unit in the second power consumption group according to a database of the first related parameter and the power consumption value of the power consumption unit in the second power consumption group established in advance.

Based on the change of the power consumption law of the power consumption unit in the second power consumption group, the database of the first correlation parameter and the power consumption value may be established in advance according to the first relevant parameter and the power consumption value according to the power consumption variation rule, thereby The first relevant parameter is monitored to query the database to obtain the power consumption value of the power consumption unit.

Exemplarily, when the power consumption unit in the second power consumption group includes the fan unit, the first relevant parameter is the fan rotation number or the base station temperature, and the fan rotation number or the base station temperature and the power consumption value of the fan unit conform to the power consumption variation rule.

Specifically, parameters such as the number of fan revolutions or the temperature of the base station can be obtained through the sensor.

Step 14: Determine a quantity of power consumption units in the third power consumption group, and obtain a power consumption value of the power consumption unit in the third power consumption group, or monitor a second related parameter of the power consumption unit in the third power consumption group and calculate Get the power consumption value.

Specifically, in the foregoing step 14, determining the number of power consumption units in the third power consumption group may include:

The number of power consumption units in the third power consumption group is determined by querying the configuration of the base station, and details are not described herein.

In the foregoing step 14, obtaining the power consumption value of the power consumption unit in the third power consumption group may include:

The input current value and the input voltage value of the power consumption unit in the third power consumption group are monitored by the sampling circuit.

Exemplarily, the power consumption unit in the third power consumption group may include a power amplifier unit. As shown in FIG. 3, in order to protect the power amplifier unit, the base station carrier frequency often designs a sampling circuit for the voltage and current of the power amplifier unit, and is used for real-time monitoring of the power amplifier unit. status. The inherent sampling circuit is used, the special measuring instrument is not added, and the equipment room transformation is not involved. The input voltage value Uin and the input current value Iin of the power amplifier unit can be obtained, and according to Pin = Uin * Iin, the input power Pin of the power amplifier unit is obtained. That is, the power consumption of the power amplifier unit is obtained? .

Exemplarily, as shown in FIG. 4, the current and voltage samples are converted by A/D (Anolog I Digital, analog/digital) and processed by an FPGA (Field-Programmable Gate Array). The CPU (Central Processing Unit) reads the input voltage value and current value of the power amplifier unit and uploads it to the BSC (Base Station Controller) through the control unit.

Alternatively, in step 14 above, the input current value and the voltage value of the power consumption unit in the third power consumption group may not be directly monitored, but The second related parameter of the power consumption unit in the third power consumption group is monitored and the corresponding power consumption value is obtained, which may include:

A second related parameter of the power consumption unit in the third power consumption group is monitored.

And obtaining, according to the relationship between the second related parameter and the second related parameter and the power consumption value, a power consumption value corresponding to the power consumption unit in the third power consumption group.

It can be seen that although the power consumption of the power consumption unit in the third power consumption group changes irregularly, based on the relationship between the second correlation parameter and the power consumption value, the second related parameter is obtained by monitoring, thereby calculating the power consumption of the power consumption unit. value.

Exemplarily, as shown in FIG. 5, when the power consumption unit in the third power consumption group includes the power amplifier unit, the second related parameter is the output power Pout of the power amplifier unit and the power amplifier efficiency II, and the power consumption P of the power amplifier unit can pass through the power amplifier unit. The output power Pout and the power amplifier efficiency II are calculated. The formula is as follows

Wherein, II represents the power amplifier efficiency, Pout represents the output power of the power amplifier unit, and P represents the power consumption of the power amplifier unit.

Power amplifier efficiency n can be obtained by query. Specifically, the power amplifier efficiency II can be obtained by querying the power amplifier efficiency curve. The power amplifier efficiency curve is the corresponding relationship between the power amplifier efficiency and the output power, and is the characteristic of the power amplifier unit, that is, the power amplifier efficiency curve of a product is certain.

The output power Pout of the power amplifier unit can be obtained by querying the input power Pin and RF (radio frequency) channel gain G of the power amplifier unit in real time, and then calculating it by the formula Pout = Pin +G.

The input power of the power amplifier unit Pin can be obtained by querying the DA conversion. Figure 5 shows TS (Time-Slot) 0-TS7, the input power of a total of 8 time slot power amplifier units Pir! .

The RF channel gain G is obtained by querying the relevant parameters of the base station carrier frequency.

Step 15. Obtain a base station power consumption value according to the number of power consumption units and the corresponding power consumption value.

Specifically, in the above step 15, the power consumption of the base station is equivalent to the power consumption sum of N ( ΓΝ) minimum power consumption units. If the power consumption of each of the smallest power consumption units is Pm and the number is M, the power consumption of the base station is simplified as a multiplication operation:

Pm = M1P1 + + MNPN.

It is worth noting that there is no strict sequence requirement between Step 12, Step 13, and Step 14 above.

Exemplarily, the indoor macro base station is taken as an example, and the number of each power consumption unit and the acquisition path of the power consumption value of each unit are described in conjunction with Table 1:

Table 1 The information acquisition channel needs to obtain the number of each power consumption unit. By querying the configuration-specific configuration conditions of each base station, the hardware analysis obtains the number of units. The TRX of each carrier frequency establishes the data power consumption value of each power consumption unit. stable

The power consumption value changes regularly. The unit's database The carrier frequency of the power amplifier single. Using the inherent sampling of the carrier frequency board, the power consumption value changes irregularly. The circuit collects the voltage and electricity of the power amplifier unit.

Stream, and thus the power consumption of the power amplifier unit,

Or obtain an amplifier by indirect testing

The power consumption of the element further, in order to obtain a more accurate power amplifier voltage and current value, the sampling period of the power amplifier voltage and current is explained. Exemplarily, as shown in FIG. 6, for a time division multiplexed GSM (Global System for Mobile Communications) system, one frame is divided into 8 TSs (Time-Slots), 8 The output powers transmitted in the time slots (TS0-TS7) will be different from each other. Therefore, to accurately measure the voltage and current of the power amplifier unit, the instantaneous voltage and current of each time slot must be collected.

A GSM time slot occupies approximately 577us. From the operability considerations, about Is collects data once, and eight acquisitions are one acquisition cycle (about 8s), that is, one acquisition cycle collects the current and voltage values corresponding to the eight time slots of one frame.

In addition, since the minimum reporting period of the statistical traffic on the BSC is 15 minutes, the minimum reporting period of the reported sample value is also 15 minutes, that is, the average value of the 110 collection periods is averaged and reported once.

Similarly, as shown in FIG. 5, the average talk time per telephone is about 45 seconds. Therefore, the period of the output power of the power amplifier unit is up to 45 seconds, and the minimum period can be adjusted according to the processor resource space. .

In order to obtain accurate power consumption of the power amplifier unit, a detailed design is performed on the sampling period of the output power of the power amplifier unit. Especially for time-division multiplexed GSM products, one frame is divided into 8 time slots, and the output power transmitted in 8 time slots will be affected by power control. Not the same, so the transmission power of 8 time slots should be collected separately.

In addition, the power consumption based on the heat dissipation unit generally does not change, so the sampling period of the voltage and current of the heat dissipation unit is not too high, and can be collected and reported in units of hours. The speed of the fan is collected, and the temperature of the fan can be collected and reported in hours. It can be seen from the technical solution provided by the foregoing embodiments of the present invention that the special measurement instrument is not added, and the equipment room transformation is not involved, and the power consumption unit of the base station is divided into power consumption groups according to the change of the power consumption thereof, thereby improving the monitoring base station.

It can be seen that the number of hardware units based on the base station is fixed, and the number of power consumption units can be obtained by querying the configuration of the base station. The power consumption of the power consumption unit in the first power consumption group is basically unchanged by the environment, the service, or the like. The change can be neglected, that is, the power consumption of the power consumption unit is stable, and the database of the power unit and the power consumption value correspondence relationship can be established in advance, thereby obtaining the power consumption value of the power consumption unit by querying the database.

Corresponding power consumption value.

It can be seen that, according to the power consumption law of the power consumption unit in the second power consumption group, the database of the first correlation parameter and the power consumption value may be established in advance according to the first relevant parameter and the power consumption value complying with the power consumption variation rule. Thereby, the power consumption value of the power consumption unit is obtained by monitoring the first relevant parameter to query the database.

The power will vary depending on the power control. Therefore, to accurately measure the voltage and current of the power amplifier, the instantaneous voltage and current of each time slot must be collected. A GSM time slot occupies approximately 577 us. From the viewpoint of operability, about one data is collected once, and eight times are collected for one acquisition period (about 8 s), that is, one collection period collects current and voltage values corresponding to eight time slots of one frame.

In addition, since the minimum reporting period of the statistical traffic on the BSC is 15 minutes, the minimum reporting period of the reported sample value is also 15 minutes, that is, the average value of the 110 collection periods is averaged and reported once. A GSM time slot occupies approximately 577us. From the standpoint of operability, about Is collects data once, and eight acquisitions are one acquisition cycle (about 8s). The time points of eight consecutive acquisitions correspond to eight time slots in one frame, respectively. The values of one acquisition cycle are averaged once, and the average value is consistent with the macro measurement.

In addition, since the period of the statistical traffic on the BSC is 15 minutes, the period for reporting the sampled value corresponds to 15 minutes, that is, the average value of the 110 acquisition periods is averaged and reported once.

The period of the statistics traffic on the BSC is 15 minutes, and the time of the user-defined time can be changed.

Exemplarily, as shown in Figure 5, the average talk time per call is about 45 seconds. Therefore, the period of collecting the output power of the power amplifier is up to 45 seconds, and the minimum period can be adjusted according to the processor resource space.

In order to obtain accurate power consumption of the amplifier, a detailed design is performed on the sampling period of the power output of the power amplifier. Especially for time-division multiplexed GSM products, one frame is divided into 8 time slots, and the output power transmitted in 8 time slots will have different effects due to power control, so the transmission power of 8 time slots should be separately collected. .

In addition, the power consumption based on the heat dissipation unit generally does not change, so the sampling period of the voltage and current of the heat dissipation unit is not too high, and can be collected and reported in units of hours. The speed of the fan is collected, and the temperature of the fan can be collected and reported in hours.
