Description
Technical field
The present invention relates to communication base station technical field, particularly, relate to a kind of base station energy-saving Intelligent fresh air system.
Background technology
Traditional base station machine room Intelligent fresh air system Problems existing sets out, the various problem occurred in working control process and shortcoming.Such as, from base station energy-saving aspect, mainly there is following problem in traditional intelligence VMC:
(1) traditional VMC logic, is not suitable for the base station being in diverse geographic location characteristic sum climate characteristic:
Traditional Intelligent fresh air system, the threshold value that some are fixing can only be set, such as open temp, the base station alarm temperature of new wind open temp, air-conditioning 1 or air-conditioning 2, the closing temperature etc. of new wind closing temperature and air-conditioning 1 or air-conditioning 2, these values are all fixed values in traditional VMC, are not suitable for the base station being in diverse geographic location characteristic sum climate characteristic.
Fixing new wind logic can only can be regarded as the most basic a kind of new wind algorithm, the energy-saving effect more optimized must have adaptive new wind logic to correspond to different base station geographic positions and climate characteristic etc., is can carry out changing with different geographical features and seasonal climate to make these threshold values in intelligent fresh air logic.
(2) the control logic of traditional VMC, does not have telemanagement and more new tool:
Due in systems in practice, each base station has different energy consumption characters, such as load of base station size, air conditioner refrigerating efficiency, base station location and climate characteristic etc., so the control Energy Saving Strategy required for each base station is also different, need to be optimized, make backstage or server will according to these actual conditions, in real time power saving logic is pushed to the VMC of each base station, carry out long-range new wind logic control, reach the managing power consumption more become more meticulous.
Tradition VMC is not because have long-range means, therefore the logic operation state of the operation maintenance personnel also current base station of there is no telling.Energy consumption management system should be the concept of a system in addition, instead of a management isolated island, and an equipment of buying is arranged on machine room, and this is far from being enough, and finally namely mismanagement is given it up.Perfect energy consumption management system not only should have local system in base station, and has background data center, and the energy consumption control data obtained will be a huge resource; Internet of Things is in the future exactly the real network producing data formation based on real world devices, and this is the Internet being different from the first generation.
(3) traditional VMC does not have Large Copacity and large computing capability to carry out new wind logic optimization in real time to carry out energy consumption data analysis:
Traditional VMC adopts single-chip computer control system mostly, and can only provide simple simply and gather and transparent transmission function, not competent more complicated local thing, even if local logic also just very simply realizes.Relative to monolithic system, even if the new wind logic that native system ARM9 system is very complicated, current processor has also just been used less than 20%, has enough resources to do poor efficiency and the non-productive work problem of other function air-conditioning of base station.
(4) the acquisition problems of new wind outdoor temperature:
When ensureing that new wind is arranged on north, new wind off-premises station produces high temperature under the direct projection of the sun, causes temperature acquisition higher than actual air temperature, decreases the time that new wind rationally runs; When outdoor warming is contained in wall face, due to the radiation response of the sun and the reflecting effect on ground, all can cause outdoor temperature data " pollution ", serious situation may cause temperature data to have the error of tens degree.Another phenomenon is exactly that outdoor warming is contained on the hook of the cover of new wind air inlet, and when blower fan is idle time, outdoor warming data are vulnerable to the pollution of Indoor Thermal air-flow.Often can see that outdoor temperature can heave a parcel phenomenon at temperature data, this acquisition problems obviously causing outdoor temperature is incorrect.
All inaccuracies that all can cause outdoor temperature data acquisition are as shown in Figure 6 above, after can cause the untrue property of new wind logic operation, make energy-saving effect produce certain infringement, the abnormal of new wind work time serious, can be caused.
(5) the interlock logical problem of fresh air conditioner:
The startup temperature difference that the new wind of tradition is arranged is fixed value, there is the risk producing ping-pong in high capacity base station; In the base station of low load, because indoor temperature is gone up comparatively slow, too highly there is again new wind utilization rate situation on the low side, so it is irrational that fixing new wind starts the temperature difference as arranged in the temperature difference that new wind starts.
The new wind principle of traditional intelligence is in base station machine room, mainly contain several equipment, except the main DC load equipment for communicating, being exactly some alternating current equipments, having comprised air-conditioning, constant temperature cabinet air-conditioning, new wind and battery rack.
Here, more sensitive to temperature is battery rack, and general battery rack needs to remain on temperature at about 25 degree.And miscellaneous equipment such as direct current and alternating current equipment do not need this to limit, and temperature can reach up to about 35 degree.How to ensure that these equipment normally can work and can also save electric energy? have employed the way of constant temperature cabinet here classically, at battery rack overcoat constant temperature cabinet, battery rack and miscellaneous equipment environment are separated consideration.Constant temperature cabinet hangs a little air-conditioning, remains on 25 degree, to make battery rack working properly.Miscellaneous equipment is then by new wind, and air-conditioning makes monolithic chamber environment remain on less than 35 degree, so both ensure that the normal operation of equipment, has economized many electric energy again to base station machine room.But the setting of new wind logic and need Different Logic strategy all to need good means to implement the execution of new wind logic for different energy consumption of machine room, it is not very large for arranging bad energy-saving effect on the contrary.Next the state carrying out simply to set forth herein new wind logic realizes.
Realizing in process of the present invention, inventor finds at least there is adaptive ability difference in prior art, communication capacity is poor, capacity is little, computing capability is weak and the defect such as temperature control poor accuracy.

In the present embodiment, the main new logic from base station energy-saving Intelligent fresh air system, new architecture and these three aspects of new data feature, the remote support means (i.e. intelligent managing power consumption operation system is called for short SEMOS) of this base station energy-saving Intelligent fresh air system are described.
In the present embodiment, from framework, base station energy-saving Intelligent fresh air system can be divided into local control section and Long-distance Control part, specific features is as follows:
(1) the feature of local control section:
1. local control system, in the local warm and humid angle value of indoor and outdoor according to collect, independently can carry out the analysis/judgement of data, and carries out further controlling behavior, comprises opening or closing of new wind and air-conditioning.There is a default control logic this locality.
2. threshold control system, has various threshold values to come startup and the closedown of various equipment in control system.As new wind start-up temperature/Income level/new wind closing temperature/air-conditioning closing temperature etc.
3. dynamic threshold system, these threshold values of VMC are on the market unmodifiable after arranging end.This does not optimize in the weather/load of base station environment of complexity change, and be sometimes not energy-conservation, the worst situation can cause equipment switching between startup with closedown very continually, and problem is that staff does not also know whether have this problem condition to occur, and thinks that new wind is working properly.
(2) the feature of Long-distance Control part
1. become more meticulous energy-saving management system, backstage or the data that server meeting is regular or each base station of real-time analysis obtains, such as load of base station size, air conditioner refrigerating efficiency, base station location and climate characteristic etc., formulate the Energy Saving Strategy of this base station, and real time propelling movement is to the VMC of each base station; This energy-saving management system that becomes more meticulous also can carry out rank to the base station energy-saving rate of this area, lists best the worst, then carries out energy-saving analysis and stragetic innovation, accomplishes more Optimization of Energy Saving management.

3. long-range new wind logical renewal system, this long-range new wind logical renewal system supports that long-range new wind logic parameter is arranged and logical renewal, similar as system software update, but this part only upgrades logical gate, reach the feature of each base station according to the different logic of different base station feature configuration.
In the present embodiment, the maximum feature of VMC new logic of this base station energy-saving Intelligent fresh air system, the threshold value controlling various equipment is exactly adaptive, according to the diverse geographic location of base station, climatic characteristic, machine room load and air conditioner refrigeration effect etc.
The intelligent fresh air new logic of this base station energy-saving Intelligent fresh air system of brief description, definable five states:
(1) S0 is the state of equipment complete shut-down; (2) S1 is that new wind is opened, the state of other complete shut-down; (3) S2 is the state that new wind is closed, air-conditioning 1 is opened, air-conditioning 2 is closed; (4) S3 is the state that the closedown of new wind, air-conditioning 1 and air-conditioning 2 are all opened; S4 be fresh air conditioner 1, the state all opened of fresh air conditioner 2.
Can suppose: air-conditioning 1 start-up temperature is Ch_Tmp1, new wind start-up temperature is Ch_Tmp2, and air-conditioning 2 start-up temperature is Ch_Tmp3, and it is Ch_Tmp4 that equipment opens temperature entirely, and there are following mapping relations between each value:
(Ch_Tmp1 Ch_Tmp2 Ch_Tmp3 Ch_Tmp4)＝f(P,Q,U,V)
P, Q, U and V in above-mentioned mapping relations on the right of equation, represent the geographical position of base station, climatic characteristic, machine room load and air conditioner refrigeration effect respectively.In the base station energy-saving Intelligent fresh air system of reality, the function f on the right of equation has different ways of realization.In addition, there are some state transfer relationships as shown in Figure 1-Figure 3 in the equation left side in above-mentioned mapping relations.
In the soaking condition transfer process figure shown in Fig. 1 and Fig. 2, there is following transfer:
(1), when environment temperature is less than new wind start-up temperature, system is in state S0;
(2), when environment temperature slowly raises, when temperature is greater than new wind start-up temperature and is less than air-conditioning 1 start-up temperature, system has transferred to state S1 from state S0, and new wind is opened;
(3) when environment temperature slowly raises, when temperature is greater than air-conditioning 1 start-up temperature and is less than air-conditioning 2 start-up temperature, system has transferred to state S2 from state S1, and new wind is closed, and air-conditioning 1 is opened;
(4), when environment temperature slowly raises, temperature is greater than air-conditioning 2 start-up temperature and is less than Ch_Tmp4 when spending, and system has transferred to state S3 from state S2, and air-conditioning 2 is opened, and air-conditioning 1 also opens;
(5), when environment temperature slowly raises, temperature is greater than Ch_Tmp4 when spending, and system has transferred to state S4 from state S3, and all devices is all opened.
In the cooling state migration procedure figure shown in Fig. 3, there is following transfer:
(1) when environment temperature slowly reduces, this base station energy-saving Intelligent fresh air system is in state S2, state S1 is transferred in the capital of S3 and S4, and namely two air-conditionings are all closed and new wind is opened;
(2) when environment temperature continues to decline, this base station energy-saving Intelligent fresh air system can transfer to S0 from state S1, and namely new wind is also closed, all devices contract fully.
In actual moving process, these start-up parameter should be dynamically changeables, and these start-up parameter need the energy consumption characters concrete according to base station to determine.
State diagram shown in above-mentioned Fig. 1, Fig. 2 and Fig. 3, also can make following straight line work sheet into, and in Fig. 4, some fixed value carrys out specific explanations use as an example, convenient understanding.
In addition, the new wind logic in above-mentioned base station energy-saving Intelligent fresh air system, is all directed to working state figure when indoor temperature is greater than outdoor.Fig. 5 give also working state figure corresponding to all temperature conditions.
In Figure 5, new wind logic can carry out redirect in lower work state diagram, considers actual indoor and outdoor temperature situation, certainly, can also add certain temperature filter action in the new wind logic of practice, make new wind logic be unlikely to redirect and very frequently produce ping-pong.
In order to overcome the defect of traditional intelligence VMC in outdoor temperature reset, can provide two kinds of solutions in the present embodiment, these two kinds all make outdoor temperature data be compensated by software way.
Solution 1: use software treating method, blower fan close before one section of outdoor temperature data area in do forward temperature prediction, extend to blower fan close scope in all do forward prediction, until next time blower fan open.
In above-mentioned formula, Z
t+t0the outdoor temp angle value at moment t+t0, Z
tthe outdoor temp angle value at moment t, a
iit is the temperature compensation coefficient of moment I.
Solution 2: use software treating method too, on the basis of front a kind of way, then the number of times of the machine that blows in when increasing some, to increase the correctness of outdoor temperature reset.Do not blow in for a long time at some the occasion of machine, the outdoor temperature reset of the machine that carries out blowing in, each opening time is about 3-4 minute, and each interval of opening is about half an hour to 1 hours.
In order to overcome the defect of traditional intelligence VMC in self adaptation facility switching threshold value, these threshold values can carry out changing with different geographical features and seasonal climate in the present embodiment.In addition, due in systems in practice, each base station has different energy consumption characters, such as load of base station size, air conditioner refrigerating efficiency, base station location, climate characteristic etc., so the control Energy Saving Strategy required for each base station is also different, backstage or server according to these actual conditions, will push to power saving logic the VMC of each base station in real time, carry out long-range new wind logic control, reach the managing power consumption more become more meticulous.
The base station energy-saving Intelligent fresh air system of the present embodiment, have employed new VMC framework, control logic is divided into two parts: local control logic (i.e. local control section) and remote control logic (i.e. Long-distance Control part), remote control logic can be referred to as server mode or cloud mode.
Local control logic is placed on the local energy saving net Central Shanxi Plain, and when intervening without remote control logic, directly just adopt local control logic, the various threshold values in local logic can be arranged according to the geographical position of this locality and climatic characteristic.Remote control logic is placed in long-range cloud computing server, cloud computing server can comprehensive data analysis that is real-time and history and excavation now, draw the control logic of this base station the most applicable and respectively control threshold value, then this base station of real-time informing, this method is called remote control logic.Remote control logic can be divided into again manual intervention logic and automatic control logic two kinds, and these two kinds of systems all adopt at real system at present, and effect is very good.
Such as, in the winter time in weather, in new wind logic, the opening and closing temperature spot of new wind can be adjusted to and follow the temperature that air-conditioning 1 or 2 is opened in summer, because in this season, outdoor temperature is almost close to the air outlet temperature value of air conditioner refrigerating, therefore this time can the new wind of long-range adjustment unlatching threshold value is set, this stylish wind facies when in air-conditioning use, substantially increase energy-conservation efficiency.
Can suppose: air-conditioning 1 start-up temperature is Ch_Tmp1+delta1, new wind start-up temperature is Ch_Tmp2+delta2, and air-conditioning 2 start-up temperature is Ch_Tmp3+delta3, and it is Ch_Tmp4 that equipment opens temperature entirely.Here air-conditioning 1, air-conditioning 2 and new wind start-up temperature, add different variable quantities (delta amount) all simultaneously, make the energy-conservation efficiency more optimized.
In the present embodiment, the new data feature of base station energy-saving Intelligent fresh air system is as follows:
