Description
Technical field
The present invention relates to the power supply power supply technique, the method that refers to a kind of backup power supply system especially and realize powering.
Background technology
As everyone knows, for assurance equipment energy reliably working, equipment disposition has primary power cource and stand-by power supply usually, general stand-by power supply is a storage battery, belongs to the part of backup power supply system, and backup power supply system can place in the equipment, also can be placed on outside the equipment, this equipment can be described as dual power supply equipment.Primary power cource is generally by mains-supplied, be power devices behind the required power supply of the equipment that converts to, when reasons such as the mains-supplied interruption occur causes the primary power cource power down, equipment sends the primary power cource power fail warning to its place network management center, and automatically switch to by backup power supply system and power, make equipment can continue to keep the work of a period of time, provide the regular hour guarantee for primary power cource restores electricity.
But the power-on time of stand-by power supply is subjected to the restriction of battery capacity, and the big more power-on time of capacity is long more, and capacity is always limited, so the power-on time of stand-by power supply also is limited.Particularly carry out such as networkings such as chain, tree types, being connected by transport module between every grade of equipment under the situation of networking at a plurality of equipment.Such as, after certain grade of equipment primary power cource power down that is arranged in chain networking, switch to by stand-by power supply to this grade power devices, guaranteed the operate as normal of equipment at the corresponding levels, the proper communication by equipment at the corresponding levels and back level equipment simultaneously makes the back level equipment also can operate as normal.After the stand-by power supply electric weight exhausted, equipment at the corresponding levels can only be deactivated, and at this moment, the equipment that is positioned at the back level also has to deactivate owing to communication disruption.In this case, if back level number of devices is many, the professional ability of whole system will be subjected to very big influence.
With the Radio Access Network is example, at present, and in wireless base system, wireless access network provides wireless access function for the user, base station and radio-frequency module such as radio frequency remoto module (RRU, Radio RemoteUnit) can carry out the networking of various forms, as: star-like, chain, tree type etc.Base station or RRU can cover certain zone, and for the user in the overlay area provides service, link to each other by transport module between the RRU at different levels and realize and the communicating by letter of base station.Fig. 1 a is the chain networking structural representation of base station and RRU, as shown in Figure 1a, adopts the chain networking mode between base station and the RRU, and concerning RRU1, the back level equipment of RRU1 comprises RRU2 and RRU3, and the higher level equipment of RRU1 is the base station.Fig. 1 b is the tree group network structural representation of base station and RRU, shown in Fig. 1 b, adopts the tree group network mode between base station and the RRU, and concerning RRU1, the back level equipment of RRU1 comprises RRU2, and RRU3 and RRU4, the higher level equipment of RRU1 are the base station.
RRU generally is furnished with backup power supply system except primary power cource, owing to reasons such as mains-supplied interruption cause under the situation of primary power cource power down, can be that RRU continues power supply by the storage battery in the backup power supply system, to prolong the operating time of RRU.
But, because the capacity of storage battery is limited, make that the power-on time of backup power supply system also is limited, supporting that if primary power cource generation power down, after the accumulator electric-quantity of RRU exhausts, RRU will withdraw from service under chain or the tree group network situation.As shown in Figure 1a, if RRU1 has enabled backup power supply system, after accumulator electric-quantity exhausts the service of withdrawing from, also have to withdraw from service because of communication disruption as the back level RRU2 of RRU1 and RRU3.When after level RRU number more for a long time, shown in Fig. 1 b,, will withdraw from service simultaneously as back level RRU2, RRU3 and the RRU4 of RRU1 if after the battery electric quantity of RRU1 exhausts the service of withdrawing from, the professional ability of whole system will be subjected to very big influence; In addition,, will cause a large amount of complaints of user, reduce the degree of belief of user network if the zone of back level RRU service is the key area.
In sum, in the prior art, the task of backup power supply system is exactly after the primary power cource power down appears in equipment, puts into the state into the entire equipment power supply, and the electric weight of storage battery exhausts in backup power supply system.Such processing, when in equipment, having big power consumption module, the electric weight that can cause backup power supply system exhausts too early, thereby cause equipment to withdraw from service too early, especially carry out the situation of networking by chain or tree type for equipment room, be easy to cause because the stand-by power supply electric weight exhausts very soon and causes communication disruption, and cause influence equipment place system service quality.

(2) in case the primary power cource power down switches to by after the backup power supply system power supply, main control module just sends classification power supplying control signal cut-off switch K to backup power supply system, makes backup power supply system enter the classification supply power mode.
(3) other preset condition, such as this equipment whether level whether be associated with back level equipment, back level equipment important etc. in network, if it is very important etc. in network that level is associated with back level equipment, back level equipment, then enter the classification supply power mode by the master control module controls backup power supply system.
(4) after the primary power cource power fail warning is received by network management center, pass through OM channel, adopt the far-end control signal to send and start the classification power supplying control signal to main control module, and then send classification power supplying control signal cut-off switch K to backup power supply system by main control module, make backup power supply system enter the classification supply power mode; Perhaps network management center is by OM channel, directly to the backup power supply system cut-off switch K that transmits control signal, cuts off the power supply of reserve battery to big power consumption module, makes backup power supply system enter the classification supply power mode.
Above condition can make up to be judged, but combination should be reasonably, such as: if be provided with condition (2) or condition (4), other condition is provided with useless so; Condition (1) can and condition (3) when being combined as power consumption at storage battery and reaching preset value and level and be associated with back level equipment, enter classification supply power mode or the like.
The description of step 302～step 303 from the method for the invention described above backup power supply system and realization power supply thereof, as can be seen: backup power supply system of the present invention provides independent function of supplying power to the big power consumption module in the equipment, promptly can be by classification power supplying control signal control stand-by power supply whether to big power consumption module for power supply, after entering the state of powering at equipment by backup power supply system, this disconnection stand-by power supply of the present invention is to the power supply of big power consumption module, the power-on time that can prolong stand-by power supply.This method can be according to user's request, and whether control cuts off the power supply of backup power supply system to big power consumption module, has reasonably prolonged the time that equipment place system can keep operate as normal, has guaranteed the professional ability of system.

Main control module: be used for the operation and the state of each module of control and management RRU, wherein, by the classification power supplying control signal, the control backup power supply system enters the classification supply power mode; By the operating state of detection signal acquisition backup power supply system, such as: whether the power-on time whether power consumption of storage battery surpasses default power consumption value, storage battery reaches default power-on time value etc.
Radio frequency power amplification modules: the wireless receiving and the sending function that are used to provide RRU.The power consumption of radio frequency power amplification modules accounts for the overwhelming majority of RRU power consumption, usually greater than 80% of complete machine power consumption.In the present embodiment, radio frequency power amplification modules is big power consumption module in RRU.
Transport module: be used to provide between RRU and the base station, and the communication port between RRU and the RRU, be used to transmit information such as data, clock.
Primary power cource:, be depicted as the primary power cource line as black thick line among Fig. 4 for each module among the RRU provides working power.
Backup power supply system: when the primary power cource power down of RRU,, be the stand-by power source line as shown in phantom in Figure 4 for each module among the RRU provides working power.Wherein, to the classification power supplying control signal that K switch sends, can disconnect the power supply of backup power supply system by main control module separately to RF Amplifier Module.Backup power supply system can place the inside of RRU, also can place the outside of RRU to become an equipment separately, and the stand-by power supply in the present embodiment in the backup power supply system is a storage battery.
As shown in Figure 4, if RRU1 the civil power interruption of power supply occurs and causes the primary power cource power down, when primary power cource can not continue power supply for RRU1, in conjunction with Fig. 3 the inventive method flow chart, the concrete course of work was as follows:
At first, judge whether power down of primary power cource, if then switching to by backup power supply system is the RRU1 power supply; Otherwise main control module continues to judge.Specific implementation and step 300～step 301 is in full accord, no longer repeats here.
In the present embodiment, because the civil power power down causes the primary power cource power down, RRU1 enters by backup power supply system working power is provided.Then, whether master control module judges satisfies the condition that starts the classification supply power mode, if satisfy, main control module sends the classification power supplying control signal to backup power supply system, cuts off the power supply of storage battery to radio frequency power amplification modules; Otherwise main control module continues to judge whether to satisfy the condition that enters the classification supply power mode.
