It is to be appreciated that the backup ring of the requirement in step (1) is exactly the backup ring formed in step (3), specifically
It is that the backup ring in step (1) is formed not yet.
The specific method is as follows:
(1) backup ring is divided
For a N:K backup ring, N-K submodule can be divided into.For example, the backup ring of a 8:6, can divide
At 2 submodules.
The dividing method of submodule is as follows.
A) N-K=1 is not divided, and second step is directly entered.
B) N-K=2 is divided into two submodules
If N, K is odd number, two submodules are respectivelyWithSuch as 11:9
Backup ring will be divided into two submodules of 6:5 and 5:4.
If N, K is even number, two submodules are for equivalentsSubmodule.
C) N-K >=3 are divided into N-K submodule.
Divide submodule, gap of the factor in need of consideration between each submodule maximal submodule small as far as possible and most boy
Difference≤2 of module.
For example, the backup ring of a 16:13, can be divided into two 6:5 submodules and a 4:3 submodule.15:12's
Backup ring can be divided into the backup ring of three 5:4, but to reduce the quantity of odd number module, be divided into 6:5,5:4 and 4:3 tri-
A module.
(2) submodule is generated
The generation basis of submodule is 4:3 module or 5:4 module, both modules become basic module, respectively such as Fig. 1 and
Shown in Fig. 2.This two kinds of modules can be used as the basis that all backup rings generate.Smaller backup ring does not discuss herein.
It is clear to refer to, as follows to switch classification naming herein:
Main part connection switch: the switch being connected with main alternate device；
Backup connection switch: the switch being connected with alternate device still claims even if being also connected with main alternate device on the switch
For backup connection switch；
Transmitting switch: be only connected with other switches the switch of equipment of being not directly connected.
As shown in Figure 1, finding out from 4:3 basic module, a basic module one shares 3 main part connection switches, 1 backup
Connection switch does not transmit switch.Main part connection switch has 4 ports, a port be used for and back up switch connection formed it is standby
Part ring basic module, a port connect main alternate device, and a port becomes connection as output port, remaining a port
End, connect for the connecting pin with other submodules, forms bigger backup ring.There are four port, a ports for backup switch
It is connect with alternate device, the other three port is connected to form three branches with other switches respectively.
As shown in Fig. 2, finding out from 5:4 basic module, a basic module one shares 3 main part connection switches, 1 backup
Connection switch, a transmitting switch.Main part connection switch has 4 ports, a port be used for and transmit switch connection formed it is standby
Part ring basic module, a port connect main alternate device, and a port becomes connection as output port, remaining a port
End, connect for the connecting pin with other submodules, forms bigger backup ring.There are four port, a ports for backup switch
It is connect with alternate device, other two port is connected as main alternate device and output end, and remaining a port and transmitting switch connect
It connects.Transmitting switch three main part connection switches of connection form three branches, form an end chain with a backup connection switch.
Generate the submodule of M:M-1.The submodule of M:M-1 is formed by basic module derivative, and specific method is known as growing.Root
Different according to the sum of backup ring, growth pattern is divided into two kinds, referred to as extends growth and derivative growth.
Extend growth: for the backup ring of N:K, as N-K≤2, i.e., composition backup ring submodule quantity≤2 when, can
Using extension growth.Extend growth i.e. on the basis of 4:3 basic module, main part connection switch and backup connection switch it
Between new main part connection switch is added, circuit sequentially operation, make branch chain elongation.As shown in figure 3, by 4:3 basic module
Branch -1 forms the basic module of a 5:4 using growth is extended.It should be raw using impartial speedup to the growth of each branch
It is long, such as the submodule to form a 7:6, it needs to increase by three main part connection switches, Ying on the basic module of 4:3
Every branch increases a switch on three branches.
Extending growth has following characteristics:
The connecting pin quantity of basic module is not will increase, therefore the connecting pin quantity of a basic module is still 3；
The quantity switched in backup ring increases identical as the increased number of backup ring gauge mould；
With the increase of backup ring module scale, it is more that equipment switches to the switch number that backup is passed through.
Derivative growth: for the backup ring of any N:K, basic module growth can be using derivative growth.
Derivative growth on the basis of 4:3 basic module, increases transmitting switch on branch, transmits two ends of switch
Mouth connects the main part connection switch and backup connection switch on former branch, other two port for transmitting switch is respectively connected to need to increase
The new main part connection switch added.As shown in figure 4, forming one using derivative growth by the branch -1 to 4:3 basic module
The basic module of 6:5.It should be using impartial speedup growth, such as the basis to form a 10:9 to the growth of each branch
Module needs to do derivative growth on every branch of the basic module of 4:3.
The characteristics of derivative growth, has:
The quantity * 2 of the quantity 3+ transmitting switch of the connecting pin of basic module, i.e., derivative number is more, connecting pin quantity
It is more；
The sum of basic module switch, such as M:M-1 module, number of switches beWherein,
Roundup operator is to round up, such as roundup (1.2)=2.
The selection of basic module, the backup ring of a N:K may be partitioned into the basic module M:M-1 of N-K, then even number is advised
The submodule (M is even number) of mould then is grown to obtain by 4:3 basic module, and the submodule (M is odd number) of odd number scale is then by 5:4 base
Plinth module generates.
(3) submodule connects
It after submodule needed for generating, needs for each submodule to be connected, forms backup ring.
Respectively using two backup connection switches as starting point, choose two submodules connecting pin be connected, herein as far as possible according to
Isometric principle connection, i.e., the switch number phase as far as possible being spaced between backup connection switch in the submodule after the connection of connecting pin belonging to it
It is same or close, until all submodule connecting pins connections that can be interconnected finish.Isometric principle is illustrated, such as Fig. 5 institute
Show, it is assumed that have the backup ring of a 14:11, be divided into the submodule of two 4:3 and the submodule of a 6:5.Figure Neutron module 1
Middle connecting pin -1 is connected by connecting line 1 with the connecting pin -1 in submodule 2.Backup connection switch in this way in submodule 1 with
Backup connection switch in submodule 2 is spaced 2 switches.Likewise, in connecting pin -5 in submodule 1 and submodule 3
Connecting pin -1 by connecting line 2 be connected, 2 switches are spaced in two backup connection switches.The connecting pin -3 of submodule 1 with
The connecting pin 3 of submodule 2 is connected by connecting line 4,3, the backup connection switch interval switch of said module.
All submodules should all be connected with other submodules, and there can be no all connecting pins of a submodule and separately
One submodule is connected.
If the sum of connecting pin is odd number, after connection is completed in all connecting pins, one and only one connecting pin is surplus
It is remaining, the connection terminating load.
If it is the quantity switched in reduction backup ring, but the submodule of backup ring is allowed to be all made of extension growth pattern.
(4) supportive to the backup of backup ring to check
When the connecting pin quantity of submodule is less than the quantity of submodule, then will appear backup ring can not support full backup
The case where switching.Such as the backup ring for 1 15:12, if cannot achieve any 3 main parts with Fig. 6 connection type
Under HPA failure, the ability of work is taken over by backup.
Transmitting switch is added in two submodule connections, can solve backup ring overall situation backup capabilities.As shown in fig. 7,
In the connecting pin of 3 5:4 submodules, increase a connection switch, which can satisfy any 3 main part amplifiers events
Barrier, the ability that can be taken over by backup.
The overall situation for meeting backup ring N:K is supportive, should ensure that in the connection of backup ring as follows:
A. work as N-K > 2, any 3 main part connection switches cannot be connected directly, i.e., after every 2 main part connection switches are connected again
It is connected with other main part connection switches, centre will increase transmitting switch；
B. when N-K >=5, it is being using 4:3 submodule, the main part connection switch being connected with the same backup connection switch is not
It can exceed that 4, that is, need to increase transmitting switch between backup connection switch and main part connection switch.
The present embodiment is able to solve the design of complicated switch backup ring, and the design constraint of this method is to form minimum backup
Ring, i.e. master switch minimum number, and the switch passed through when meeting and making under the premise of user's requirement and switch to backup from main part
Minimum number.
