Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
The embodiment provides a modularized design method for a backup ring of a satellite-borne transponder, which comprises the following steps:
(1) dividing the required backup ring to form each submodule needing to grow;
(2) according to each submodule needing to be grown in the step (1), the basic module generates each required submodule through prolonged growth or derivative growth;
(3) connecting all required sub-modules to form a backup ring;
(4) and meeting the backup support of the backup ring according to the connection condition of the backup ring.
It should be understood that the backup ring required in step (1) is the backup ring formed in step (3), and specifically, the backup ring in step (1) is not formed yet.
The specific method comprises the following steps:
(1) backup ring partitioning
For an N: K backup ring, it can be split into N-K sub-modules. For example, an 8:6 backup ring may be split into 2 sub-modules.
The partitioning method of the sub-modules is as follows.
a) And (3) directly entering the second step without segmentation, wherein the N-K is 1.
b) N-K2 is divided into two submodules
If N, K is odd, the two submodules are respectively
And
for example, an 11:9 backup ring, would be split into two sub-modules, 6:5 and 5: 4.
If N, K is even, the two submodules are of equal form
And (5) sub-modules.
c) N-K is more than or equal to 3 and is divided into N-K submodules.
And dividing the submodules, wherein the factor to be considered is that the difference between the maximum submodule and the minimum submodule is less than or equal to 2 when the difference between the submodules is as small as possible.
For example, a 16:13 backup ring may be divided into two 6:5 sub-modules and a 4:3 sub-module. A 15:12 backup ring may be divided into three 5:4 backup rings, but into three modules of 6:5,5:4 and 4:3 to reduce the number of odd modules.
(2) Generating sub-modules
The generation basis of the sub-modules is 4:3 or 5:4 modules, which become the basic modules, as shown in fig. 1 and 2, respectively. Both modules can be the basis for all backup ring generation. The smaller backup ring is not discussed here.
For clarity of reference, the switch classes are named here as follows:
the master part is connected with the switch: a switch connected to the master device;
a backup connection switch: the switch connected with the backup device is still called as a backup connection switch even if the switch is also connected with the master device;
a transfer switch: the switches are connected only to other switches and not directly connected to the device.
As shown in fig. 1, from the 4:3 base module, one base module has 3 primary connection switches, 1 backup connection switch, and no transfer switch. The main connection switch is provided with 4 ports, one port is used for being connected with the backup switch to form a backup ring basic module, one port is connected with the main equipment, one port is used as an output port, and the other port is used as a connecting end and is used for being connected with the connecting ends of other sub-modules to form a larger backup ring. The backup switch has four ports, one port is connected with the backup device, and the other three ports are respectively connected with other switches to form three branched chains.
As shown in fig. 2, as seen from the 5:4 base module, there are 3 primary connection switches, 1 backup connection switch, and one transfer switch for one base module. The master connection switch is provided with 4 ports, one port is used for being connected with the transfer switch to form a backup ring basic module, one port is connected with the master device, one port is used as an output port, and the other port is used as a connecting end and is used for being connected with the connecting ends of other sub-modules to form a larger backup ring. The backup switch has four ports, one port is connected with the backup device, the other two ports are used as the connection and output end of the master device, and the remaining one port is connected with the transfer switch. The transfer switch is connected with the three main part connecting switches to form three branched chains, and the three branched chains and a backup connecting switch form an end chain.
And generating sub-modules of M: M-1. M: the submodule of M-1 is derived from the basic module, a specific method called growth. The growth regimes are divided into two, termed elongation growth and derivative growth, depending on the total number of backup loops.
And (3) prolonging growth: for the backup ring of N: K, when N-K is less than or equal to 2, namely the number of the sub-modules forming the backup ring is less than or equal to 2, the prolonged growth can be adopted. And the extension growth is that on the basis of a 4:3 basic module, a new main connection switch is added between the main connection switch and the backup connection switch, and the cyclic operation is performed in sequence to extend the branched chain. As shown in FIG. 3, a 5:4 building block was formed by using elongation growth for branch-1 of the 4:3 building block. Equal acceleration growth should be adopted for growth of each branched chain, for example, if a 7:6 submodule is to be formed, three main connecting switches should be added on a 4:3 basic module, and one switch should be added on each branched chain of the three branched chains.
The prolonged growth has the following characteristics:
the number of the connection ends of the base module is not increased, so that the number of the connection ends of one base module is still 3;
the number of switches in the backup ring is increased by the same amount as the increase of the scale of the backup ring;
with the increase of the scale of the sub-module of the backup ring, the number of switches for switching the equipment to backup is large.
And (3) derivative growth: for any N: K backup ring, the growth of the basic module can adopt derivative growth.
The derivation growth is that on the basis of a 4:3 basic module, a transfer switch is added on a branched chain, two ports of the transfer switch are connected with a master connection switch and a backup connection switch on the original branched chain, and the other two ports of the transfer switch are respectively connected with a new master connection switch needing to be added. As shown in FIG. 4, a 6:5 building block was formed by using derivatization growth for branch-1 of the 4:3 building block. An equal acceleration rate should be used for growth of each branch, for example, if a 10:9 basis module is to be formed, a derivative growth is required on each branch of the 4:3 basis module.
The characteristics of the derivative growth are as follows:
the number of the connecting ends of the basic module is 3+ the number of the transfer switches is 2, namely the more the derived counts are, the more the connecting ends are;
total number of base module switches, e.g. M: m-1 module with a number of switches of
The roundup operator is rounding up, for example, roundup (1.2) ═ 2.
The selection of the basic module, an N: K backup ring, can be divided into N-K basic modules M: M-1, so that even-scale submodules (M is even) are grown from 4:3 basic modules, and odd-scale submodules (M is odd) are generated from 5:4 basic modules.
(3) Submodule connection
After the required sub-modules are generated, the sub-modules need to be connected to form a backup ring.
The two backup connection switches are respectively taken as starting points, the connection ends of the two sub-modules are selected to be connected, and the connection ends are connected according to the equal length principle as much as possible, namely, the number of the switches at intervals between the backup connection switches in the sub-modules to which the connection ends belong is the same or similar as much as possible after the connection ends are connected until the connection of all the sub-module connection ends which can be connected with each other is finished. To illustrate the equal length principle, as shown in FIG. 5, assume that there is a 14:11 backup ring divided into two 4:3 sub-modules and a 6:5 sub-module. The connecting end-1 in the sub-module 1 is connected with the connecting end-1 in the sub-module 2 through a connecting wire 1. So that the backup connection switch in submodule 1 is spaced from the backup connection switch in submodule 2 by 2 switches. Similarly, the connection terminal-5 in the sub-module 1 is connected with the connection terminal-1 in the sub-module 3 by the connection line 2, and 2 switches are separated between the two backup connection switches. The connecting end-3 of the sub-module 1 is connected with the connecting end 3 of the sub-module 2 through a connecting wire 4, and the backup connecting switches of the modules are 3 switches at intervals.
All sub-modules should be connected to other sub-modules, and it cannot happen that all connection terminals of one sub-module are connected to another sub-module.
If the total number of the connection terminals is an odd number, one and only one connection terminal remains after all the connection terminals are connected, and the connection terminals the load.
If the number of switches in the backup ring is reduced, the submodules of the backup ring all adopt an extended growth mode.
(4) Checking backup support of a backup ring
When the number of the connecting ends of the sub-modules is less than the number of the sub-modules, the situation that the backup ring cannot support all backup switching occurs. For example, for 1 15:12 backup ring, if the connection mode of fig. 6 is used, the capability of taking over the work by the backup under any 3 primary HPA failures cannot be realized.
A transfer switch is added in the connection of the two sub-modules, so that the global backup capability of the backup ring can be realized. As shown in fig. 7, a connection switch is added at the connection end of 3 5:4 sub-modules, and the backup ring can meet the fault of any 3 main share amplifiers and can be replaced by the backup.
To satisfy the global support of the backup ring N: K, the following should be ensured when the backup ring is connected:
a. when N-K is more than 2, any 3 master connection switches can not be directly connected, namely every 2 master connection switches are connected with other master connection switches, and a transfer switch is added in the middle;
b. when N-K is more than or equal to 5, if the 4:3 submodule is used, the number of the main share connecting switches connected with the same backup connecting switch cannot exceed 4, namely a transfer switch needs to be added between the backup connecting switch and the main share connecting switch.
The embodiment can solve the design of the complex switch backup ring, and the design constraint of the method is to form the minimum backup ring, namely the total switch number is minimum, and the number of switches passing through when switching from the master to the backup is minimum on the premise of meeting the requirements of a user.
The above-described embodiments are merely preferred embodiments of the present invention, and general changes and substitutions by those skilled in the art within the technical scope of the present invention are included in the protection scope of the present invention.
