Description

Technical Field

[0001] The invention relates to the field of satellite overall circuit design, in particular to a communication series satellite power distribution cable contact distribution design system. Background Art

[0002] The distributor is a key device in the satellite power supply and distribution subsystem. Its function is to reliably complete the distribution of power distribution points for satellite primary power units according to the satellite's mission characteristics and power demand of the power units. With the significant improvement in the payload configuration and performance of communication satellites, the corresponding satellite power demand has increased significantly, and the number and types of power units have increased. It is of great significance to ensure the power supply safety of power units, improve the main and backup power supply interfaces, and the high-reliability distribution point allocation design of the main and backup units' redundant backup.

[0003] The traditional distribution cable contact design method requires manual design of the distribution cable contacts for the entire satellite power unit. During the design process, the power distribution capacity of each distributor, distribution module, and electrical connector under the distribution module must be considered. At the same time, the distribution power of each distributor, each distribution module, and each electrical connector must be as balanced as possible. For the main power unit with a main and backup distribution interface, different distribution modules must be selected to distribute the distribution contacts of the main / backup distribution interface. When the module that the distributor distributes power to the main distribution interface of the single unit fails, the module that distributes power to the backup distribution interface of the single unit can work normally, thereby improving the reliability of power distribution. For power units of the same series that adopt the single-machine backup form, it is necessary to ensure that the power units are evenly distributed under different distribution modules and different electrical connectors under the same distributor. When a distribution module or electrical connector fails, it will not affect the power supply of the units in the same series.

[0004] As the power demand of communication satellites increases significantly, the number and types of power units are increasing. The traditional design method of power distribution cable joints is time-consuming, error-prone, and inefficient, and cannot meet the increasing model mission requirements. Summary of the invention

[0050] In order to better understand the technical solution of the present invention, the specific implementation mode of the present invention is described in detail below with reference to the accompanying drawings.

[0051] The present invention provides a communication series satellite power distribution cable contact distribution design system, comprising:

[0052] An input module receives a satellite power distribution auxiliary table and a power consumption unit auxiliary table; the satellite power distribution auxiliary table includes power distribution unit location information, and the power consumption unit auxiliary table includes power consumption equipment location information;

[0053] The parsing module obtains a list of the power distributor and the power consumption equipment located at the same location according to the power distributor location information and the power consumption equipment location information;

[0054] The sorting module sorts the power consumption units according to the type of the power consumption units; the power consumption units are divided into three types, the type I power consumption unit contains a main power supply interface and a backup power supply interface; the type II power consumption unit only contains a single main power supply interface; the type III power consumption unit is a plurality of units of the same series, each of which contains only a single power supply interface, but adopts a single machine backup form; the three types of power consumption units at the same location are sorted from large to small according to power, and when the power of different types of power consumption units is the same, they are sorted according to the priority of type I power consumption unit> type II power consumption unit> type III power consumption unit;

[0055] The power distribution module uses the power distributor at the same location to allocate power distribution contacts to the three types of power-consuming units at that location in the order in which the power-consuming units are sorted.

[0056] Specifically, the design process is as follows Figure 1As shown. The satellite distributor and power-consuming unit auxiliary table are input into the system. The distributor auxiliary table contains "distributor name", "distribution module number", "electrical connector code", and "distributor location information"; the power-consuming unit auxiliary table contains "power-consuming equipment name", "power-consuming equipment power", "power-consuming equipment type", and "power-consuming equipment location information"; the system parses the distributor and power-consuming unit auxiliary tables, and sorts out the distributors and power-consuming equipment at the same location based on the "distributor location information" and "power-consuming equipment location information".

[0057] For example, the "service cabin south board", the electrical equipment on the service cabin south board all use the service cabin south board's distributor for power distribution, and the electrical equipment at the same location use the distributor at the same location for power distribution, thus avoiding the problem of "long detours" in the distribution cables and improving the reliability of the distribution of distribution points.

[0058] Furthermore, according to the auxiliary table of power-consuming units, the types of power-consuming units are analyzed. Here, power-consuming units are divided into three categories: Type I power-consuming units contain primary and backup power supply interfaces, and the power supply interfaces inside the power-consuming units are redundantly backed up; Type II power-consuming units contain only a single primary power supply interface, and the power supply interfaces inside the units are not redundantly backed up; Type III power-consuming units refer to multiple units of the same series, which only contain a single power supply interface, but adopt a single-machine backup form. The three types of power-consuming units in the same location are sorted from large to small according to power. When the power of different types of power-consuming units is the same, they are sorted according to the priority of Type I power-consuming units>Type II power-consuming units>Type III power-consuming units.

[0059] Based on this general principle for allocating distribution points, it can be ensured that the distribution power of each distribution module under the distributor and the distribution power of the electrical connector under each module are as balanced as possible, avoiding the situation where the distribution power of a certain distribution module or electrical connector exceeds its distribution power upper threshold while the remaining multiple distribution points of another distribution module or electrical connector are not in use.

[0060] Furthermore, the distributor at the same location is selected. The distributor is composed of Figure 2 As shown in FIG. 1 , a power distributor is composed of m (m = 1, 2, ..., M) identical power distribution modules, each of which contains c (c = 1, 2, ..., C) identical electrical connectors, each of which contains 1A-5B and 250W distribution channels, a total of 11 distribution contact resources, such as Figure 3 In the satellite power distribution cable point distribution design system, each distributor u is equipped with a main power pool P 主 (U u ), 1 backup power pool P 备 (U u )、1 flag counter flag(U u );Each power distribution module m is equipped with a main power pool P主 (U u ,M m ), 1 backup power pool P 备 (U u ,M m ), 1 flag counter flag (U u ,M m ); Each electrical connector c is provided with a main power pool P 主 (U u ,M m ,C c ), 1 backup power pool P 备 (U u ,M m ,C c ), 1 flag counter flag (U u ,M m ,C c ).

[0061] Furthermore, after the three types of power-consuming units at the same location are sorted in descending order of power, the distributor at the same location selects the electrical connector distribution channel under the distribution module to allocate distribution contacts; when different types of power-consuming units with the same power appear at the same location, distribution contacts are allocated in the order of priority: Type I power-consuming unit > Type II power-consuming unit > Type III power-consuming unit.

[0062] The distribution contact allocation process of type I power consumption unit is as follows: Figure 4 As shown, assuming that the power of a single machine of type I is P t , select the same position distributor u, first allocate the distribution points for the main distribution interface of the power-consuming single machine, and determine whether the electrical connector contained in the distributor u has distribution points. If not, the system will automatically report an error prompt that the distributor has no distribution points; if yes, select the main power pool P in the distribution module under the distributor u. 主 (U u ,M m ) The smallest power distribution module. After selecting the power distribution module m, determine whether the electrical connector contained in the power distribution module m of the power distribution device u has a power distribution contact. If not, delete the power distribution module m in the power distribution device u and select the main power pool P from the remaining M-1 power distribution modules. 主 (U u ,M m ) the smallest power distribution module; if there is one, select the main power pool P in the power distribution module m under the power distribution u 主 (U u ,M m ,C c) the smallest electrical connector, determine whether the electrical connector c in the power distribution module m of the power distribution device u has a power distribution contact, if not, delete the electrical connector c in the power distribution module m of the power distribution device u, and select the main power pool P from the remaining C-1 electrical connectors 主 (U u ,M m ,C c ) the smallest electrical connector; if there is one, the distribution points are allocated to the main power distribution interface of the I-type power consumption unit in the order of electrical connectors 1A to 5B and 250W distribution channels. At this time, the main power pool P of the distributor u 主 (U u )=P 主 (U u )+P t , the main power pool P of the distribution module m under the distribution device u 主 (U u ,M m )=P 主 (U u ,M m )+P t , electrical appliances u under the power distribution module m in the electrical connector c main power pool P 主 (U u ,M m ,C c )=P 主 (U u ,M m ,C c )+P t . After the distribution contacts of the main power distribution interface of a type I power consumption unit are allocated, select the same power distribution unit u to allocate the distribution contacts of the backup power distribution interface of the power consumption unit, delete the distribution module m allocated to the distribution contacts of the main power distribution interface, and select different distribution modules to allocate the distribution contacts of the main / backup power distribution interface of the type I power consumption unit. When the module that the power distribution unit uses to distribute power to the main power distribution interface of the single-machine fails, the module that distributes power to the backup power distribution interface of the single-machine can work normally, thereby improving the reliability of power distribution. After deleting the remaining M-1 distribution modules after the distribution module m under the power distribution unit u, determine whether the electrical connector contained in the power distribution unit u has distribution contacts. If not, the system will automatically report an error prompt that the power distribution unit has no distribution contacts. If so, select the backup power pool P 备 (U u ,M m ) the smallest power distribution module; after selecting the power distribution module m', determine whether the electrical connector contained in the power distribution module m' of the power distribution device u has a power distribution contact. If not, delete the power distribution module m' in the power distribution device u, and select the backup power pool P from the remaining M-2 power distribution modules 备 (U u ,M m) the smallest power distribution module; if so, select the backup power pool P in the power distribution module m' under the power distribution u 备 (U u ,M m ,C c ) the smallest electrical connector, determine whether the electrical connector c' in the power distribution module m' of the power distribution device u has a power distribution contact, if not, delete the electrical connector c' in the power distribution module m' of the power distribution device u, and select the backup power pool P from the remaining C-1 electrical connectors 备 (U u ,M m ,C c ) the smallest electrical connector; if there is one, the distribution contacts are allocated to the Class I power stand-alone backup power distribution interface in the order of electrical connectors 1A to 5B and 250W distribution channels. At this time, the backup power pool P of the distributor u 备 (U u )=P 备 (U u )+P t , the power distribution module m' under the distributor u is the main power pool P 备 (U u ,M m )=P 备 (U u ,M m )+P t , the power distribution module m' in the electrical connector c' backup power pool P of the electrical appliance u 备 (U u ,M m ,C c )=P 备 (U u ,M m ,C c )+P t . Complete the distribution contact allocation of Type I power consumption units.

[0063] The distribution contact allocation process of type II single-unit power consumption is as follows: Figure 5 As shown in the figure, the power distribution contact logic of the type II power consumption unit is the same as the power distribution contact allocation of the main power supply interface of the type I power consumption unit. Assuming that the power of the type II power consumption unit is P t , select the same position distributor u, first allocate the distribution points for the main distribution interface of the power-consuming single machine, and determine whether the electrical connector contained in the distributor u has distribution points. If not, the system will automatically report an error prompt that the distributor has no distribution points; if yes, select the main power pool P in the distribution module under the distributor u. 主 (U u ,M m) The smallest power distribution module. After selecting the power distribution module m, determine whether the electrical connector contained in the power distribution module m of the power distribution device u has a power distribution contact. If not, delete the power distribution module m in the power distribution device u and select the main power pool P from the remaining M-1 power distribution modules. 主 (U u ,M m ) the smallest power distribution module; if there is one, select the main power pool P in the power distribution module m under the power distribution u 主 (U u ,M m ,C c ) the smallest electrical connector, determine whether the electrical connector c in the power distribution module m of the power distribution device u has a power distribution contact, if not, delete the electrical connector c in the power distribution module m of the power distribution device u, and select the main power pool P from the remaining C-1 electrical connectors 主 (U u ,M m ,C c ) the smallest electrical connector; if there is one, the distribution points are allocated to the main power distribution interface of the I-type power consumption unit in the order of electrical connectors 1A to 5B and 250W distribution channels. At this time, the main power pool P of the distributor u 主 (U u )=P 主 (U u )+P t , the main power pool P of the distribution module m under the distribution device u 主 (U u ,M m )=P 主 (U u ,M m )+P t , electrical appliances u under the power distribution module m in the electrical connector c main power pool P 主 (U u ,M m ,C c )=P 主 (U u ,M m ,C c )+P t .

[0064] The distribution contact allocation process of type III single-unit power consumption is as follows: Figure 6 As shown, assuming that the power of a single machine of the same series of type III is P t , select the same position distributor u, first for the distributor u flag counter flag (U u )、Distribution module m flag counter flag(U u ,M m ), electrical connector c flag counter flag (U u ,Mm ,C c ) is set to zero. Select the flag counter flag (U u ) the smallest distributor, to determine whether there are multiple distributor flag counters flag (U u ) the same situation, if yes, then add auxiliary conditions, for the selection of the primary / backup of the same series of type III power consumption units, select the same flag (U u ) The main power pool of the distributor P 主 (U u ) or backup power pool P 备 (U u )The smallest distributor u. Next, select the flag counter flag (U u ,M m ) The smallest power distribution module. Similarly, if the power distribution unit has multiple power distribution module flag counters (U u ,M m ) the same situation, then add auxiliary conditions, for the selection of the primary / backup of the same series of type III power units, select the same flag (U u ,M m ) The main power pool P of the power distribution module 主 (U u ,M m ) or backup power pool P 备 (U u ,M m ) The smallest power distribution module m. Next, select the flag counter flag (U u ,M m ,C c ) The smallest electrical connector. Similarly, if the power distribution module has multiple electrical connector flag counters (U u ,M m ,C c ) the same situation, then add auxiliary conditions, for the selection of the primary / backup of the same series of Class III power units, select the same flag (U u ,M m ,C c ) Main power pool P of the electric connector 主 (U u ,M m ,C c ) or backup power pool P 备 (U u ,M m ,C c) The smallest electrical connector c. Next, determine whether the electrical connector contains a power distribution point. If so, select the main / backup status of the same series of type III power units. If it is a type III main power unit, then the main power pool P of the power distributor u is 主 (U u )=P 主 (U u )+P t , the main power pool P of the distribution module m under the distribution device u 主 (U u ,M m )=P 主 (U u ,M m )+P t , the main power pool P of the power distribution module m in the power distribution device u 主 (U u ,M m ,C c )=P 主 (U u ,M m ,C c )+P t , the u flag counter of the distributor u )=flag(U u )+1, the flag counter of the power distribution module m under the power distribution device u (U u ,M m )=flag(U u ,M m )+1, the flag counter of the electrical connector c in the power distribution module m under the power distribution device u (U u ,M m ,C c )=flag(U u ,M m ,C c )+1; if it is a Type III backup power unit, then the backup power pool P of the distributor u 备 (U u )=P 备 (U u )+P t , the backup power pool P of the power distribution module m under the power distribution device u 备 (U u ,M m )=P 备 (U u ,M m )+P t , the backup power pool P of the power distribution module m in the power distribution unit u 备 (U u ,M m,C c )=P 备 (U u ,M m ,C c )+P t , the u flag counter of the distributor u )=flag(U u )+1, the flag counter of the power distribution module m under the power distribution device u (U u ,M m )=flag(U u ,M m )+1, the flag counter of the electrical connector c in the power distribution module m under the power distribution device u (U u ,M m ,C c )=flag(U u ,M m ,C c )+1. If the electrical connector has no distribution contacts, delete the electrical connector and reselect from the remaining C-1 electrical connectors of the same distribution module; if none of the C electrical connectors in the distribution module have distribution contacts, delete the distribution module and reselect from the remaining M-1 distribution modules of the selected distributor. If the electrical connectors of all distribution modules under the distributor have no distribution contacts, an error message will be displayed to indicate that the distributor has no distribution resources. After the distribution contacts of the Type III series power consumption units are allocated in sequence, the u flag counter flag (U u )、Distribution module m flag counter flag(U u ,M m ), electrical connector c flag counter flag (U u ,M m ,C c ) is set to zero.

[0065] Through this distribution method, under the premise of ensuring that the distribution power of each distribution module under the distribution device and the distribution power of the electrical connector under each module are as balanced as possible, the Type III power-consuming units can be evenly distributed under different distribution modules and different electrical connectors under the same distribution device. When a distribution module or electrical connector fails, it will not affect the power supply of the units in the same series, which greatly improves the safety and reliability of the distribution cable contact design.
