Description

Technical Field

[0001] This invention belongs to the field of launch vehicle control systems, specifically relating to a method and apparatus for parallel power supply of dual systems. Background Technology

[0002] In launch vehicles, the basic stage and upper stage each have independent control systems. During the basic stage flight phase, the basic stage control system controls the entire rocket's flight, while the upper stage serves as the payload of the basic stage. After separation, the upper stage operates independently. During ground testing, they are powered by ground power from their respective ground-based telemetry, launch, and control systems. Before liftoff, they are powered by their respective batteries. To meet the onboard power requirements, the ground-based telemetry, launch, and control systems typically incorporate remote voltage regulation circuits. These circuits connect the positive and negative lines of the feedback point to the remote load, ensuring that the operating voltage of the remote equipment remains within a set range. Simultaneously, the power outputs of the basic stage and upper stage are confined within their respective stage sections. During the basic stage flight phase, the upper stage equipment requires power, which is supplied by the upper stage's batteries.

[0003] In certain application scenarios, while maintaining the independence of the base stage and the upper stage, the base stage needs to provide operating power to the upper stage during the flight phase to reduce battery consumption in the upper stage. However, the current solution of enclosing the power distribution output within the stage segment cannot meet this requirement. Summary of the Invention

At this time, the external feedback terminal of the upper-level ground power supply is floating, and the upper-level ground power supply enters the local voltage regulation state and outputs voltage according to the set voltage.

[0016] Upper-level ground voltage regulation point status: By connecting the external feedback terminal of the upper-level ground power supply to the upper-level ground voltage regulation point through the upper-level voltage regulation switching circuit, the upper-level ground power supply enters the remote voltage regulation state, ensuring that the power supply in the upper-level generator control assembly is within the set voltage range.

[0017] Upper stage arrow voltage regulation point status: By connecting the external feedback terminal of the upper stage ground power supply to the upper stage arrow voltage regulation point through the voltage regulation switching circuit, the upper stage ground power supply enters the remote voltage regulation state, ensuring that the power supply to the upper stage arrow is within the set voltage range.

[0026] A method for operating a dual-system parallel power supply device, characterized in that it includes the aforementioned dual-system parallel power supply device and comprises the following steps:

[0027] 1. Before ground-based power transfer, the foundation stage, upper stage ground equipment, and onboard equipment are powered separately without affecting each other;

[0028] 2. During ground-to-ground power transfer, the basic-level ground computer sends a power transfer command to the basic-level power distributor, which then switches to basic-level battery power supply. During ground testing, a basic-level analog cable is used instead of the basic-level battery power supply. At the same time, the upper-level power distribution output of the basic-level power distributor supplies power to the upper-level output to provide working power for the upper-level.

[0030] The beneficial effects of this invention are as follows:

[0031] 1. The present invention provides a dual-system parallel power supply device and method, which realizes that under the premise that the basic stage and the upper stage of the launch vehicle are independent, the basic stage of the flight segment provides working power to the upper stage, and the upper stage switches to self-powered power supply before the basic stage and the upper stage are separated, thereby reducing the battery consumption of the upper stage;

[0032] 2. Different voltage regulation modes are used for the upper stage and the base stage ground power supply. The upper stage adopts the "local-ground-on-rocket" voltage regulation mode, and the base stage adopts the "local" voltage regulation mode, which solves the voltage regulation competition problem when the two sets of measurement, launch and control systems are connected in parallel.

[0033] 3. The basic-level power distributor is divided into two modules: "upper-level power distribution" output and "basic-level power distribution output". This not only enables power distribution output to the upper level, but also ensures the independence of the basic level.

[0037] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.

[0038] Example 1

[0039] This application discloses a dual-system parallel power supply device, such as... Figure 1 As shown, it includes: upper-level systems and basic-level systems.

[0040] The upper stage system includes: the upper stage rocket system and the upper stage ground system.

[0041] The upper stage onboard system includes: upper stage battery, upper stage power distributor, and other upper stage equipment; the upper stage ground system includes: upper stage ground power supply, upper stage ground computer, and upper stage launch and control assembly.

[0042] The basic-level system includes: the basic-level onboard system and the basic-level ground system.

[0043] The basic-level onboard system includes: basic-level battery, basic-level power distributor, and other basic-level equipment; the basic-level ground system includes: basic-level ground power supply, basic-level ground computer, and basic-level launch control assembly.

[0044] The upper-stage ground power supply provides operating power to the upper-stage system and is connected to the upper-stage generator-control assembly (GCA). The GCA, controlled by the upper-stage ground computer, distributes the operating power provided by the upper-stage ground power supply to the upper-stage power distributor. The upper-stage power distributor receives instructions from the upper-stage computer and distributes the operating power from the ground to other equipment on the upper-stage rocket. The upper-stage power distributor is also connected to the base-stage power distributor, receiving power outputs and transfer commands from the base-stage power distributor. It distributes the operating power distributed by the base-stage power distributor to other equipment on the upper-stage rocket and can also receive transfer commands from the base-stage power distributor to power the upper-stage battery.

[0045] A voltage regulation feedback point is set within the upper-level power distribution unit, called the upper-level arrow-mounted voltage regulation point. This feedback point is connected to the voltage regulation switching circuit of the upper-level ground-based power generation and control assembly. A voltage regulation feedback point is also set within the upper-level ground-based power generation and control assembly, called the upper-level ground-based voltage regulation point. One end of the voltage regulation switching circuit in the upper-level ground-based power generation and control assembly is connected to the external feedback terminal of the upper-level ground power supply, and the other end is connected to its voltage regulation switching point. By controlling the voltage regulation switching circuit, the voltage regulation switching point can be in three states: "suspended," upper-level ground-based voltage regulation point, and upper-level arrow-mounted voltage regulation point. Figure 2 As shown. The voltage regulation switching circuit is controlled by the upper-level ground computer. When the upper-level ground computer is selected in the "floating" state, the voltage regulation switching point is floating, and the external feedback terminal of the upper-level ground power supply is also floating. The upper-level ground power supply enters the local voltage regulation state and outputs voltage according to the set voltage. When the upper-level ground computer is selected in the "ground voltage regulation point" state, the voltage regulation switching point in the upper-level ground generator-control assembly is connected to the ground voltage regulation point in the generator-control assembly. At this time, the external feedback terminal of the upper-level ground power supply is also connected to the ground voltage regulation point, and the upper-level ground power supply enters the remote voltage regulation state, regulating voltage according to the set voltage to ensure that the power supply in the generator-control assembly is within the set voltage range. When the upper-level ground computer is selected in the "arrow-mounted voltage regulation point" state, the voltage regulation switching point in the upper-level ground generator-control assembly is connected to the arrow-mounted voltage regulation point in the upper-level power distribution unit. At this time, the external feedback terminal of the upper-level ground power supply is also connected to the arrow-mounted voltage regulation point, and the upper-level ground power supply enters the remote voltage regulation state, regulating voltage according to the set voltage to ensure that the power supply on the upper-level arrow is within the set voltage range. The upper-stage ground computer controls the switching of the voltage regulation point according to the test procedure. Before the upper-stage ground generator control assembly supplies power, the voltage regulation point is set to the "suspended" state. After the upper-stage ground generator control assembly is powered on, the voltage regulation point is set to the "ground voltage regulation point" state. After power is supplied to the upper-stage rocket, the voltage regulation point is set to the "rocket voltage regulation point" state.

[0046] The base-level ground power supply provides operating power to the base-level system and is connected to the base-level generator-control assembly. The base-level generator-control assembly is controlled by the base-level ground computer, which allocates the operating power provided by the base-level power supply to the base-level power distributor. The base-level power distributor receives instructions from the base-level computer and distributes the operating power from the ground to other equipment on the base-level rocket, or to the upper-level power distributor. The base-level power distributor has two types of power outputs: base-level power output and upper-level power output. These two types of outputs can be controlled independently and distributed in a time-sharing manner as needed. Generally, power is first supplied to the base-level outputs, and then to the upper-level outputs during power transfer. Similar to the upper level, when the external feedback terminal is floating, the base-level ground power supply enters a local voltage regulation state and outputs the set voltage.

[0047] A voltage regulation feedback point, called the base-level on-arrow voltage regulation point, is set within the base-level power distributor. This feedback point is connected to the base-level ground control and generation assembly. A voltage regulation feedback point, called the base-level ground voltage regulation point, is also set within the base-level ground control and generation assembly. The base-level ground control and generation assembly has a voltage regulation switching circuit. One end of this circuit is connected to the external feedback terminal of the base-level ground power supply, and the other end is connected to its voltage regulation switching point. By controlling the voltage regulation switching circuit, the voltage regulation switching point can be in three states: "floating," base-level ground voltage regulation point, and base-level on-arrow voltage regulation point. The base-level voltage regulation switching point is controlled by the base-level ground computer. Its voltage regulation point setting and adjustment method is the same as the previous level, except that the base-level ground computer always sets the voltage regulation point to the "floating" state, and the base-level ground power supply always operates in the local voltage regulation state.

[0048] The dual-system parallel power supply device in this application embodiment operates in a "local-ground-arrow" voltage regulation mode for the upper stage and in a local power supply voltage regulation mode for the basic stage.

[0049] As an extension of the embodiments of this application, other devices at the upper level include devices in the upper level that can access the bus system, such as upper-level inertial navigation systems, upper-level servos, upper-level receivers, etc., which can be added or removed according to the needs of system design; other devices at the basic level include devices in the basic level that can access the bus system, such as basic-level inertial navigation systems, basic-level servos, basic-level receivers, etc., which can be added or removed according to the needs of system design. These devices do not affect the implementation of the embodiments of this application.

[0053] (2) During ground-based power transfer, a power transfer command is sent from the ground-level computer to the base-level power distributor to transfer the power to the base level.

[0054] The basic stage is powered by a battery. During the basic stage flight phase, the basic stage battery provides power for the basic stage and the upper stage.

[0055] (3) Before the upper stage is separated from the base stage, the base stage power distributor sends a power transfer command to the upper stage power distributor to switch to power supply to the upper stage battery.

[0056] (4) During the upper stage flight phase, the upper stage battery provides power for the upper stage to operate.
