Abstract
The invention discloses a method for prolonging the electricity supplying time of a storage battery. The storage battery is used for supplying electricity in a base station and is provided with at least three threshold value voltages according to the discharge characteristic of the storage battery, wherein one threshold value voltage is a blackout voltage v <d>, and other threshold value voltages are both greater than the blackout voltage v <d>. The discharge voltage V <f> output by the storage battery is detected and is compared with every threshold value voltage to judge the discharge capacity reduction of the storage battery and hierarchical regulation total power consumption. Because the hierarchical regulation total power consumption is used, the present invention can prolong the electricity supplying time of the storage battery. As long as V <f> is greater than V <d>, base station important load electricity supply is reserved, and the service time of personal communication business in mobile users in a base station coverage residential area is prolonged.
Description
Technical field
The present invention relates to communication equipment and adopt storage battery power supply, particularly relate to a kind of storage battery power supply time method that is used to prolong.
Background technology
At present, the outdoor version macro base station in the communication system generally all is equipped with storage battery, so that after the Alternating Current Power Supply outage, continues as the macro base station power supply by storage battery, to ensure the proper communication of communication system.
See also Fig. 1, the networking of existing base station is adopted in the chain communication mode, controls a plurality of base stations by a base station controller.Wherein, connect successively until base station N-1, base station N in base station controller, base station 1, base station 2.Base station 1 is directly with base station controller communication; Base station 2 connects base station 1, and passes through base station 1 with base station controller communication; Base station 3 connects base station 2, and communicates by letter with base station controller by base station 2, base station 1; By that analogy, connecting base station N-1, base station N-2 until base station N communicates by letter with base station controller until base station 2, base station 1.Therefore, the base station in the communication system not only possesses the function that Personal Communications Services is provided for its coverage cell, also possesses the function that transmission channel is provided for other base stations and base station controller simultaneously.Thereby, if in the communication system in case there is a base station not interrupt transmitting because of there being sufficient power supply, communicating by letter and will be interrupted between base station and the base station controller in the whole system then.
This shows that the storage battery that the base station is equipped with must possess sufficient discharge capacity to ensure sufficient power-on time.If there is not alternating current for a long time, battery capacity emptying, the base station will not have power supply and service disconnection occur.
But in actual applications, the discharge capacity of storage battery is big more, and its volume is also just big more, causes cost correspondingly to improve simultaneously.Therefore, in view of the consideration of volume and cost, the battery discharging finite capacity that existing outdoor version macro base station is equipped with, storage battery is that the power-on time of base station is also correspondingly more limited.
In addition, according to the discharge principle of storage battery, the long-term emptying of battery capacity is prone to damage.In existing design, system detects battery discharging voltage, and (this threshold values can be set, and for the cell batteries of 2V, is set at 1.8V usually when being lower than certain cut-ff voltage Vd; For the cell batteries of 12V, be set at 10.8V usually.), system will cut off being connected of storage battery and base station.Therefore, storage battery will be more limited to the time of base station power backup.
In order to prolong the power-on time of storage battery, in actual applications by the carrier frequency of control base station, the method that reduces its transmitting power or close all carrier frequency reduces the total power consumption of base station, with the power-on time of further prolongation storage battery.
The communication base station system comprises main control unit, Base Band Unit, transmission unit, radio-frequency (RF) power amplification unit and auxiliary unit.Wherein Base Band Unit, transmission unit, main control unit are guaranteed communicating by letter of base station and base stations control, belong to important load (also claiming the second load); Radio-frequency (RF) power amplification unit and auxiliary unit belong to less important load (also claiming the principal load).
The radio-frequency (RF) power amplification unit can be divided into a plurality of power grades, and the power grade value of different base station is set according to local networks planning and optimization situation, and not heightening or turn down of power grade can influence mobile communication business, only influences network communication quality.It is bigger that the power of radio-frequency (RF) power amplification unit accounts for total base station power proportion.With the base station that disposes 6 power amplifiers is example, the about 1080W of power amplifier gross power during the full power emission, account for 70% of total base station power (about 1550W), if power amplifier power reduces 3db (50%), the power amplifier gross power is 630W, and then total base station power is 1100W, reduce by 30%, therefore can effectively reduce total base station power by the class of emission that reduces the radio-frequency (RF) power amplification unit, to prolong the charging time of storage battery
Only set a threshold value (that is threshold voltage) of storage battery output voltage in the prior art; When alternating current cut off the power supply, it was each unit power supply in the base station that storage battery at first comes with the predetermined power grade; Monitoring storage battery output voltage in case when the output voltage of storage battery is lower than threshold value, turn-off all principal loads in the base station, is only given the second electric of base station.
In a single day the output voltage that detects storage battery by said method is lower than threshold value, carrier frequency unit and power amplifier unit in the base station can all be turned off, storage battery is only given main control unit, base band and the transmission unit power supply of enable transmission, thus the power-on time that can prolong storage battery.But, in application in practice,, thereby cause the mobile subscriber's Personal Communications Services in this sub-district to be interrupted in case after carrier frequency unit in the base station and power amplifier unit can all be turned off, the mobile subscriber in the sub-district that the base station covered can't be linked into this base station.
