The purpose of design of system diagram has two, and one is to represent all devices, device, antenna, the Topology connection of feeder line to close
System, two be represent in vertical shaft longitudinal direction how cabling, what line walked.How the key of system G- Design is by signal source（A bit）
Power reasonably distribute according to need to each antenna（Multiple spot）, i.e. need to design and somewhere place what device to ensure
The reasonability of power distribution.Generally speaking, the design of system diagram is exactly that how much work(needed according to signal source how many power, antenna
How rate, decision reasonably distributes these power.
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with specific embodiment, and reference
Accompanying drawing, the present invention is described in more detail.
Fig. 1 is the power distribution method flow chart of indoor distributed system of the present invention, and this method comprises the following steps：
S101, on plan batch or mark out individually each antenna and its required power, each antenna to device installation
The cabling route and line style of feeder line between point or vertical shaft.
S102, by frame choosing the antenna on plan, feeder line, device mount point or vertical shaft etc. are automatically generated in system diagram
On, power and feeder loss according to needed for antenna, the feeder line of each antenna of connection rises at comptograph part mount point or vertical shaft
Power required for top, and by its ascending automatic longitudinal arrangement.
So-called frame choosing is exactly the antenna in region, the feeder line chosen by square frame with mouse standardized square frame on plan
Etc. will automatically generate on system diagram.
Below in conjunction with instantiation, illustrate the feeder line initiating terminal that each antenna is connected at calculating device mount point or vertical shaft
The process of required power.For example, we set power needed for antenna A1-F1 as 2dBm, from the antenna to vertical shaft
Feed line length be 50 meters, feeder loss be hundred meters of 7dB/, then at vertical shaft connect A1-F1 antennas feeder line initiating terminal needed for work(
Rate be 2+50/100*7=5.5dBm, wherein power needed for antenna by designer it is single or batch set.Other antennas are all according to this
Mode is calculated, and whole calculating process is calculated completion by computer automatically.
Assuming that certain floor of building one has 10 antennas, according to method described above, the feeder line that this 10 antennas are connected rises
Power needed for top according to order longitudinal arrangement from small to large, the purpose for the arrangement is that in order to by required power it is close as far as possible
It is arranged together, so as to be connected using suitable device.
Insertion Loss difference between S103, each output port of difference power and passive device according to needed for adjacent feeders is passive to select
Device, by a plurality of feeder line tandem to a passive device, and calculates the power needed for passive device input port.According to this side
Formula is by all antennas all tandems to one or several passive devices in a floor.The passive device include power splitter and
Coupler.
Passive device how is selected for the ease of description, 3 conditions are first defined.
Definition condition is to illustrate in what situations using the connection of what device.The order of Rule of judgment is from condition 1
To condition 3.Meet a kind of connected mode of each condition correspondence.In the device used in the industry at present, output port is at most
It is four output ports of the input port of four power splitters, i.e., one, it is can be four demand power tandems into a demand work(
Rate, so it is just much of that at most to compare four demand powers.
Condition 1：Insertion Loss between each output port of 1st article of feeder line and the 4th article of difference power needed for feeder line and power splitter is poor
（0dB）Between difference be no more than the first setting value, such as 2dB（Variable）；
Condition 2：Insertion Loss between each output port of 1st article of feeder line and the 3rd article of difference power needed for feeder line and power splitter is poor
（0dB）Between difference be no more than the second setting value, such as 2dB（Variable）；
Condition 3：Insertion Loss between each output port of 1st article of feeder line and the 2nd article of difference power needed for feeder line and power splitter is poor
（0dB）Between difference be no more than the 3rd setting value, such as 2dB（Variable）.
If meeting condition 1, preceding 4 feeder lines are connected using four power splitters, and the 5th article of feeder line is designated as automatically
Feeder line 1, feeder line below is designated as feeder line 2,3,4 etc. successively；
If being unsatisfactory for condition 1, but condition 2 is met, then connected preceding 3 feeder lines using three power splitters, and by the 4th
Bar feeder line is designated as feeder line 1 automatically, and feeder line below is designated as feeder line 2,3,4 etc. successively；
If condition 2 is not satisfied, but meet condition 3, then preceding 2 feeder lines are connected using two power splitters, and by the 3rd
Bar feeder line is designated as feeder line 1 automatically, and feeder line below is designated as feeder line 2,3,4 etc. successively；
If being unsatisfactory for condition 3, selection coupler two output port Insertion Loss difference is closest with difference power needed for two feeder lines
Coupler preceding 2 feeder lines are connected, the coupled end of coupler connection feeder line 1 leads directly to end connection feeder line 2, and by the 3rd article
Feeder line is designated as feeder line 1 automatically, and feeder line below is designated as feeder line 2,3,4 etc. successively.
More than each step complete to be both needed to after connection to mark required performance number foremost in inserter instrument.
For example, certain floor has 10 antennas, power sequential needed for the initiating terminal of its corresponding each feed line be A10
A07 A08 A09......, it is corresponding needed for power be respectively 2.7/3.0/4/0/4.1dBm.......Due to A10 and A09 couples
The difference power answered（4.1-2.7=1.4dBm）In 2dBm（First setting value）, so by A10 A07 A08 A09 feeder line connect
It is connected to four power splitters.
Wherein, the operation for calculating the power needed for passive device input port is：Take power needed for connected feeder line
Maximum and minimum value, be then averaging, obtain to the loss of corresponding output port plus passive device input port respectively
Power to needed for passive device input port.
Or by taking above-mentioned example as an example, then the power needed for the input port of four power splitters is：
Take A10 A07 A08 power needed for A09 antennas and its feeder line maximum 4.1 and minimum value 2.7, add respectively
Then the input port of four power splitters is averaging to the loss 6.5 and 6.5 of output port, obtains four power splitter input port institutes
The power needed, i.e., (（4.1+6.5）+（2.7+6.5）〕/2=9.9dBm.
Similarly, selection using another four power splitter by A02 A04 A03 A06 tandems, needed for the four power splitters input port
Power be 11.7dBm；Using two power splitters by A01 A05 tandems, the power needed for two power splitter input ports is
10.4dBm.Thus by all 10 antennas of the floor and its all tandems of corresponding feeder line to two four power splitters and one
On two power splitters.
Insertion Loss difference between S104, each output port of difference power and passive device according to needed for adjacent passive device is selected
The passive device of insertion is selected, by multiple passive device tandems to a passive device to be inserted, and the passive of insertion is calculated
Power needed for device input mouthful.In this manner by all passive device tandems of insertion to one or more passive devices
On.So operate repeatedly, until all antennas, feeder line, device tandem of the floor are untill a passive device.This is just completed
The Automated Design of flat bed system diagram.
If general power needed for a flat bed system diagram is no more than the first setting value, such as 10dBm（Variable）, to avoid
Backbone power dissipation, then by S103 and S104 operation, a flat bed system diagram is connected with adjacent flat layer system figure, shape
Into a new flat bed system diagram.Now just complete the Automated Design of flat bed system diagram
In S104, the operation for selecting the passive device of insertion is：
Compare the power needed for preceding 4 devices, if the difference power needed for any two of which device is no more than first
Setting value, such as 2dB（Variable）, then preceding 4 devices are connected using four power splitters；
If difference power needed for wherein there are two devices is more than the first setting value, more preceding 3 devices it is required
Power, will be first 3 using three power splitters if the difference power needed for any two of which device is no more than the first setting value
Device is connected；If the difference power needed for there are two devices in preceding 3 devices compares the first two device more than the first setting value
The two, if its required difference power is no more than the first setting value, is connected by part using two power splitters；If its required power surpasses
The first setting value is crossed, then the two is connected with its immediate coupler using two output port loss differences, connected mode is coupling
Close lower-powered device needed for the connection of port, the larger device of power needed for the connection of coupler straight-through port.
More than each step complete to be both needed to after connection to mark required performance number foremost in inserter instrument.
The operation for calculating the power needed for the passive device input port of insertion is：Take the passive device institute being attached thereto
Need the maximum and minimum value of power, respectively plus insertion the corresponding input port of passive device to output port loss,
Then it is averaging, the power needed for the passive device input port inserted.
According to above-mentioned example, the difference power needed for the power splitter of above-mentioned two four and two power splitters is no more than 2dB, institute
So that a three power splitter tandems should be used, i.e., three devices are respectively connecting to the output port of three power splitters, three power splitters
Input port needed for power be：
〔（The power splitter insertion loss of 11.7+ tri-）+（The power splitter insertion loss of 9.9+ tri-）〕/2=〔（11.7+5.5）+
（9.9+5.5）〕/2=14.1dBm.
By now, all flat bed system diagrams have been generated, i.e., each layer of antenna all tandems a to passive device
It is upper, for example, antenna A01-A10 all tandems are on three power splitters.
The whole process of the step is automatically performed by computer, and this causes design standard to be able to unification, and power distribution is more
Rationally, it also avoid power dissipation.
S105, the position and power distribution direction for selecting active equipment.What the operation can automatically be pointed out according to software covers
Lid scope is selected.If prompting has power margin on distribution direction, also need further to select power margin reserved location
Etc. information.
Due to by active equipment power distribution to the position of this operation of flat bed system and active equipment, the side of power distribution
To relevant, and also relate to if also have after the power distribution of active equipment is to all floors it is more than needed if this how to handle.
So needing user to select which layer active equipment position, power distribution direction, and power margin are reserved in.
Judge for the ease of user, after user selectes active equipment position, system can point out can to cover upwards how much
Layer, how many layer can be covered downwards, if having power margin, and reference is provided for user's selection power distribution direction.If power
Have more than needed, user is also an option which layer power margin is reserved in.After these parameters are selected, system can be automatically performed
Source device and the Topology connection of floor system, i.e., complete connection between active equipment and flat bed system diagram with what device.
S106, selection passive device, connect active equipment, i.e., power to be allocated is passive by the input port of passive device
The input port of the appointed output terminal mouthful connection floor tandem device of device, that is, need distribution power, the connection of another output port
Floor gap connects feeder line, i.e., new power to be allocated.So operate repeatedly, until the power to be allocated of active equipment is divided completely
Match somebody with somebody.If the power distribution of active equipment give all floors after, also there is power margin, then be reserved in specified location or
As virtual active equipment, S105~S106 is repeated in other floors.If the power of only one active equipment fails point
All floors of dispensing, then repeat S105~S106 operations, until all floors are all assigned to the unallocated floor to power
Untill required power.Now just complete the automatic distribution of active equipment power.
For the ease of description, first illustrate be available for user select several power distribution directions and its with device location
Relation：
Direction 1：Upwards, if user selects this direction, active equipment position is in floor minimum in coverage.
Direction 2：Downwards, if user selects this direction, active equipment position is in highest floor in coverage.
Direction 3：Get on, get off：If user selects this direction, active equipment position be in coverage in the middle of certain
Floor.
Direction 4：It is first up and then down：If user selects this direction, active equipment position be in coverage in the middle of certain
Floor.
Afterwards, two kinds of power distribution algorithms are re-defined：
Forward power allocation algorithm：Power to be allocated is poor with needing distribution power to make, when it is damaged with the insertion of two power splitters
Consumption difference is no more than the 4th setting value, such as 1dB（Variable）When, two power splitters are selected, otherwise select the degree of coupling most to connect therewith
The two is connected by near coupler, and connected mode is the input port that power to be allocated connects two power splitters（The input of coupler
Port）, need distribution power to connect an output port of two power splitters（The coupling aperture of coupler）.Another of two power splitters is defeated
Exit port（Coupler it is straight-through）Floor gap connection feeder line is connected, herein as the starting point of new power to be allocated, is treated with original
Distribution power subtracts two power splitter Insertion Loss（The straight-through loss of coupler）, again subtract floor gap connecting line loss, its result conduct
New power to be allocated.
Reverse power allocation algorithm：Since the distalmost end floor of overlay area, if power subtractive needed for adjacent two floor
The feeder loss of floor gap is gone to be no more than the 5th setting value, such as 2dB（Variable）,（Wherein, all antennas of adjacent two floor
All respective tandem is on a device）, then that device of two floors is connected using two power splitters, connected mode is two
The larger floor of power needed for the output port connection of power splitter, its another port connection floor gap feedback of two power splitters
Line, lower-powered floor needed for the other end connection of feeder line, and by mean power needed for two floors（Feeder line containing floor gap is damaged
Consumption）Plus two power splitter Insertion Loss new distribution power is needed as one；
If difference power is more than the 5th setting value, such as 2dB needed for adjacent two floor（Variable）, then using the degree of coupling with
Insertion Loss difference coupler immediate therewith is connected, coupled end connection floor gap feeder line, power needed for the connection of the feeder line other end
Less floor, leads directly to the larger floor of power needed for the connection of end, and by power needed for two floors（Feeder loss containing floor gap）
Plus being averaged after the degree of coupling or Insertion Loss, along with the connecting line of floor gap is lost, its result needs distribution power as new.
Above-mentioned forward power allocation algorithm and reverse power allocation algorithm are to be used to distribute active equipment（Or signal source）Work(
Rate, in units of active equipment, each active equipment is required for by being so assigned.
For S105 and S106, it is described below in the case of having selected power distribution direction and inactivity more than needed, has
The power distribution operation of source device：
User's selection power distribution direction is direction 1（Or direction 2）, inactivity is had more than needed, then completely using forward power point
Power distribution is carried out with algorithm.
User's selection power distribution direction is direction 3（Or direction 4）, inactivity is had more than needed, then first using reverse power distribution
Algorithm is calculated to active equipment site layer from the minimum or uppermost storey in coverage, then using forward power allocation algorithm pair
Remaining floor carries out power distribution.
It is described below in the case of having selected power distribution direction and having had power more than needed, the power point of active equipment
With operation：
User's selection power distribution direction is direction 1（Or direction 2）, there is power and have more than needed, then first using reverse power point
Calculated with algorithm from the farthest floor in coverage to power margin and reserve layer, then using forward power allocation algorithm from active
Layer where equipment calculates to power margin and reserves layer, the power margin and reverse power that last forward power allocation algorithm is calculated
The required power that allocation algorithm is calculated is connected by forward power allocation algorithm, and the difference between the two stays in reserved as power margin
Layer, i.e., be no longer allocated for power margin.
User's selection power distribution direction is direction 3（Or direction 4）, there is power and have more than needed, then first using reverse power point
Calculated with algorithm from the farthest floor in coverage to nearest power margin and reserve layer or active equipment site layer, then used
Forward power allocation algorithm calculates to power margin from layer where active equipment and reserves layer, by last forward power allocation algorithm meter
The power margin of calculation is connected with the required power that reverse power allocation algorithm is calculated by forward power allocation algorithm, the difference between the two
Reserved layer is stayed in as power margin, i.e., is no longer allocated for power margin.
User's selection distribution direction, the distribution direction can be any of the above-described direction, and power to be allocated is with needing distribution power
Difference is no more than the 6th setting value, such as 1dB（Variable）, then the two is joined directly together.That is, this kind situation may be considered and treat
Power to be allocated then is fully allocated to need distribution power by distribution power with needing distribution power basically identical.
User's selection distribution direction, the distribution direction can be any of the above-described direction, and power ratio to be allocated needs distribution power
It is small（Such case is considered as power margin for negative value）, and difference absolute value more than the 6th setting value, such as 1dB（It is variable
Amount）, then the system diagram for needing distribution power floor is broken step by step, part therewith direct phase of the selection closest to power to be allocated
Even, remainder with reference to S103 and S104 operation formed one newly need distribution power floor.
Below by one embodiment, the power allocation procedure of active equipment is illustrated.
For example, certain building amounts to 10 layers, 5 meters of floor height.It is upward to select coverage direction, and software prompt has power margin, choosing
It is 9 layers to select power margin and reserve layer.The power output of active equipment is 30dBm, and every layer of flat bed system needs the distribution power to be
11dBm, active equipment position is 1 layer, then first from apart from layer where equipment（1 layer）Farthest 10 layers are reverse to calculate pre- to power
Stay 9 layers of layer, it should using two power splitters by 9,10 layers of tandem device be connected, power needed for two power splitters is [11+（11+9、10
Interlayer feeder loss）The power splitter insertion loss of/2+ bis-]=[11+（11+0.4）/ 2+3.5]=14.6dBm, this power is 9,10
The required power of layer；Again from layer where active equipment（1 layer）Start, by active equipment power output compared with power needed for 1 layer
Compared with, the insertion of 20dB couplers should be used between, i.e. 20dB coupler inputs mouthful connection active equipment output port,
Coupling aperture connects the input port of 1 layer of tandem device, and the power output of straightthrough port subtracts floor feeder loss and treated point as new
It is 2 Layer assignment power with power, then new performance number to be allocated is：30- couplers -5 meters of feeder losses of straight-through loss）=30-
0.4-0.4=29.2dBm。
According to 2,3,4 ... Layer assignment power are followed successively by this way, it is assigned to always after 9 layers, remaining power to be allocated
For 22.0dBm, according to forward power allocation algorithm, remaining power to be allocated and 9,10 layers need used between distribution power
7dB couplers are connected, the remaining power to be allocated of coupler input mouthful connection, coupling port connection 9,10 layers of need distribution work(
Rate, the straight-through port of coupler is reserved in 9 layers as power margin, and its power is 22.0-1.4（The straight-through loss of coupler）=
20.6dBm。
The whole process of the step is automatically performed by computer, it is ensured that uniformly reasonably press the power of active equipment
Need distribution so that design standard is able to unification, power distribution is more reasonable, it also avoid power dissipation.
As shown in figure 1, after this step, following operation can also be included：
S107, connection active equipment and source device.To ensure the flexibility of conceptual design, and consider this part workload
It is smaller, it is possible to by the annexation of user's designed, designed active equipment.
The overall power that S108, computer are automatically performed from source device to antenna is calculated and mark.
After the annexation of the complete active equipment of user's designed, designed, a complete system topological connection is just fully completed
.Order is automatically updated by power, system automatic can carry out power distribution from source device to antenna direction and calculate with updating,
And need mark place mark out power distribution to herein when be how many.Due to being all reverse in design process before this
, that is be all to need how much power to be designed as starting point, but it is actual real can distribute how much power be it is positive,
So it is accomplished by all power forward directions to distribute one time.Complete to update and mark.
The present invention completes a large amount of artificial work using computer, realize indoor distributed system power distribution it is automatic
Change, substantially increase design efficiency, also ensure that the accuracy and reasonability of power distribution, reduce error probability.The present invention is set
The power algorithm of rational distribution according to need is counted so that indoor distributed system conceptual design job specification is unified, reasonable in design, office
The adjustment of portion or the overall situation becomes very simple for designer, all.
