Description
Technical Field
[0001] The present invention belongs to the technical field of power supply in complex environments, and in particular relates to an integrated redundant mutual backup power supply system in complex environments. Background Art
[0002] With the continuous development of modern intelligent submersibles and aircraft, the importance of stable and durable power supplies has become increasingly prominent. Submersibles are often used for missions such as deep-sea exploration, seabed resource exploration, and military reconnaissance. Operating in extremely harsh environments, a stable power supply is crucial. Submersibles face the risk of power board failure or malfunction while operating in the deep sea. Redundant, mutually backed-up power systems can extend mission duration and ensure their safe return. Especially during long-term ocean exploration or undersea operations, redundant, mutually backed-up systems can improve mission safety and success rates. In the military, if a submarine's main system fails while submerged, critical equipment such as sonar, radar, and communications systems remain operational, safeguarding the submarine's stealth and combat capabilities.
[0003] Aircraft are also highly dependent on power, and redundant backup systems can play a vital role in multiple scenarios. Drones are often used for long-distance or long-duration missions, such as logistics transportation, border patrols, and exploration. Equipping a redundant backup system can prevent drones from losing control and crashing if the main power board fails, and increase their service life. Spacecraft (such as satellites, space stations, and probes) must operate in extreme environments. A failure in the main system could lead to mission failure or even loss of contact with Earth. In such situations, the role of redundant backup systems is crucial, ensuring that the spacecraft can maintain the operation of core systems such as communications, navigation, and attitude control to complete the mission or return safely. In the military, backup power supplies can ensure the continued operation of aircraft such as fighter jets and unmanned reconnaissance aircraft during missions. Especially in high-risk environments, if the main system is attacked or fails, the backup system can maintain combat capability.
[0004] Advances in battery technology have led to the emergence of lithium-ion batteries, solid-state batteries, and hydrogen fuel cells. To meet the weight and space requirements of aircraft and submersibles, power systems must become more compact, lightweight, and efficient. In the future, renewable energy sources such as solar energy could serve as auxiliary power sources for submersibles and aircraft. Therefore, to improve mission sustainability and reliability, higher requirements are being placed on existing power systems. However, existing power systems suffer from low physical integration, imperfect fault switching mechanisms, and poor environmental adaptability. Summary of the Invention

DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, not all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0021] Example 1 like Figures 1 to 5As shown, the first embodiment of the present invention provides an integrated redundant mutual backup power supply system in a complex environment, comprising: a sealed cabin 1, wherein the surface of the sealed cabin 1 is provided with an input power interface 2 and an output power interface 14; a plurality of integrated boards 12 connected in a cascade manner are provided in the sealed cabin 1, and each integrated board 12 is provided with a control circuit 11 and a plurality of input contact pins 5 and a plurality of output contact pins 8; the input contact pins 5 and the output contact pins 8 on each integrated board 12 are electrically connected in a one-to-one correspondence, and the input power interface 2 and the output power interface 14 are connected to the input contact pins 5 and the output contact pins 8 on the integrated board 12 respectively; The input contact pin 5 is used to input the voltage input from the input power interface 2 or the input contact pin 5 of the previous integrated board 12 into the control circuit 11 at this level or transmit it to the input contact pin 5 on the next integrated board 12; the output contact pin 8 on each integrated board 12 is used to transmit the output contact pin 8 on the adjacent integrated board 12 or the voltage output from the control circuit 11 at this level to the output power interface 14 in sequence through the output contact pin 8 of the adjacent integrated board 12; in each integrated board 12, the control circuit 11 is electrically connected to one of the input contact pins 5 and one of the output contact pins 8, respectively, for stabilizing the input voltage on the connected input contact pins 5 and outputting it through the output contact pin 8.
[0022] Specifically, if Figures 4-6 As shown, in this embodiment, the input power interface 2 and the output power interface 14 are respectively arranged at both ends of the sealed cabin 1; the input contact pins 5 of the first integrated board 12 are connected to the various connection terminals of the input power interface 2, and the output contact pins 8 of the last integrated board 12 are connected to the various connection terminals of the output power interface 14.
[0023] Specifically, if Figure 3 As shown, in this embodiment, the input contact column 5 on the first integrated board is connected to the various connection terminals of the input power interface 2 through the wire 3, and the output contact column 8 on the last integrated board 12 is connected to the various connection terminals of the output power interface 14 through the wire 3.
[0024] Furthermore, if Figures 3 and 4 As shown, the integrated redundant mutual backup power supply system in a complex environment of this embodiment also includes a sealing partition 13, which divides the space in the sealed cabin 1 into a plurality of mutually isolated sealed spaces; each integrated board 12 is arranged in one of the sealed spaces, and the sealing partition 13 is provided with a through-hole for penetrating the input contact column 5 and the output contact column 8.
[0025] Specifically, in this embodiment, the column holes are sealed to achieve sealing of the spaces between the sealing partitions 13. When water enters one of the sealed spaces, the standby integrated boards in the other sealed spaces can be guaranteed to work normally and start the backup.
[0026] Specifically, in this embodiment, the control circuit 11 on the integrated board 12 includes a short-circuit protection module, a voltage stabilizing module, and an undervoltage protection module. The voltage input by the input contact column 5 is output to the corresponding output contact column 8 after passing through the short-circuit protection module, the voltage stabilizing module, and the undervoltage protection module in sequence.
[0027] Specifically, in this embodiment, each input contact column 5 corresponds to an operating voltage, and the voltage input by each input contact column 5 is connected to at least two integrated boards 12; one of which is a main integrated board and the rest are spare integrated boards. The control circuit 11 of the spare integrated board also includes a main control module, a relay switch and a detection module. The relay switch is arranged between the short-circuit protection module and the voltage stabilizing module. The detection module is used to detect the voltage on the corresponding output contact column 8 and send it to the main control module. The main control module is used to control the relay switch to close according to the detection situation and connect the spare integrated board to the circuit.
[0028] Specifically, in this embodiment, each integrated board 12 is provided with three input contact pins 5 and three output contact pins 8. The three input contact pins 5 are respectively used to connect to a DC power supply voltage such as 24V, 48V, or 5V. The three input contact pins 5 output voltages of 24V, 5V, and 3.3V, respectively. The control circuit 11 is used to step down and stabilize the input voltage. Six integrated boards 12 are installed within the sealed cabin body 1, two for each voltage, one active and one standby. When the detection module on the corresponding standby integrated board detects the disappearance of the voltage signal on the corresponding output contact pin, the main control module controls the corresponding relay switch to close, and the standby integrated board begins to connect to the circuit and begin operation, continuously supplying power to subsequent devices. Specifically, in this embodiment, the input contact pins 5 and output contact pins 8 on each integrated board 12 are arranged symmetrically. This allows the same layout design to be used for each integrated board. During installation, the integrated board 12 of different voltages simply needs to be rotated 60° and then plugged in.
[0029] Furthermore, in this embodiment, the number of integrated boards 12, and the number of input contact pins 5 and output contact pins 8 on each integrated board 12, can be increased or decreased based on the application scenario. For example, if the input voltage types are 24V and 48V, and the output voltage types are 24V, 12V, 5V, and 3.3V, at least four main integrated boards are required. Assuming one spare, eight integrated boards 12 are required; two input contact pins 5 are required, and four output contact pins 8 are required. The positions of the input contact pins 5 and the output contact pins 8 on each integrated board 12 correspond to each other, and the circuit installation and connection can be completed by plugging the contact pins together.
[0030] Furthermore, in this embodiment, each integrated board 12 is also provided with a GND contact pin 4. The GND contact pins 4 on each integrated board are electrically connected in sequence and connected to the ground wires on the input power interface 2 and the output power interface 14. Specifically, the GND contact pin 4 on the first integrated board 12 is connected to the ground wire on the input power interface 2, and the GND contact pin 4 on the last integrated board 12 is connected to the ground wire on the output power interface. Furthermore, in this embodiment, the GND contact pin 4 on each integrated board 12 is disposed at the center of the sealed cabin 1.
[0031] Furthermore, in this embodiment, the input contact pins 5 and output contact pins 8 comprise a socket base and a plug pin. The socket base is used to connect to the plug pins on the next-level integrated board, and the plug pin is used to plug into the socket base on the previous integrated board. The input contact pins 5 and output contact pins 8 are positioned in a one-to-one correspondence on each integrated board 12. The plug pins and socket bases cooperate to achieve electrical connection between the integrated boards 12. Furthermore, in this embodiment, the input contact pins 5 and output contact pins 8 can also be connected to the integrated board of the current level and the previous level by welding.
[0032] Furthermore, in this embodiment, the sealed cabin 1 is filled with sealant to achieve waterproof and pressure-proof properties; the input power interface 2 and the output power interface 14 are designed to be waterproof.
[0033] like Figure 7As shown, another embodiment of the present invention provides an integrated redundant, mutually backed-up power supply system for complex environments. The system includes two different input voltages and two different output voltages. Each integrated board 12 is provided with two input contact pins 5 and two output contact pins 8. Path A is provided with one primary and two backup voltages, and Path B is provided with one primary and one backup voltage. Therefore, there are five integrated boards in total, enabling two voltage paths. If a backup integrated board fails, another backup integrated board will take over its function, and so on. Furthermore, the input contact pins 5 and output contact pins 8 can also be set as backups. When an input contact pin 5 connected to an integrated board fails and cannot provide normal power, the integrated board's control circuit detects the loss of the electrical signal on the input contact pin 5 and automatically switches to the backup input contact pin 5, replacing the damaged input contact pin 5 to power the backup integrated board, achieving a backup effect. The same applies to the output contact pins 8. In other words, each input contact pin 5 and output contact pin 8 can transmit different voltages, or they can be set as backup contact pins to transmit the same voltage, thereby enhancing the stability of the redundant, mutually backed-up system.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
