The described embodiments should not be construed as limiting the present application. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0034] In the following description, reference is made to "some embodiments", which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0036] An on-board laboratory refers to a mobile scientific research or testing facility installed on a ship, which is used to carry out scientific experiments, data analysis, environmental monitoring, medical research, etc. in a marine or inland river environment. It combines the mobility of the ship and the professional functions of the laboratory, and is widely used in the fields of marine science, military, medical, environmental protection, etc.

[0037] In the related art, with the continuous development of the technology of on-board laboratories, there are more and more on-board laboratories of scientific research ships with different functions. Each functional on-board laboratory operation needs to be equipped with precision instrument equipment. Usually, such precision instruments have extremely high requirements for the stability, continuity and anti-interference of power supply. Limited by the complexity of the ship environment, there is currently no dedicated power supply system for on-board laboratory equipment on board. Usually, it adopts the form of unified power supply with other on-board equipment and instruments, which has a great impact on the service life and operation safety of precision instruments. Land laboratories usually adopt the method of independent space for each single precision instrument device and single uninterruptible power supply for each single device for independent power supply, which requires a large space and has a high maintenance cost.

[0038] It should be noted that many on-board laboratory equipment belongs to precision instruments, which usually have three characteristics: high sensitivity and vulnerability, the need for uninterrupted operation, and a complex power usage environment. The microelectronic components in precision instruments are extremely sensitive to voltage fluctuations. The pulsed voltage generated when high-power instruments start up can easily cause reading fluctuations, component damage, or data loss. Some field operation experiments usually need to last for several days. The ship runs unstably, and sudden power loss will lead to experiment failure or damage to precious samples. When the power supply lines of on-board laboratory equipment and other high-power equipment (such as refrigerators, air conditioners, etc.) are not isolated, it is easy to cause electromagnetic interference and voltage fluctuations. The space of the on-board laboratory is limited, and it is impossible to provide independent power supply for each precision instrument. Some small precision instruments will be moved back and forth during offshore operations, and the instrument power supply system needs to consider flexibility. The ship environment is complex, and there are risks such as on-board laboratory fires and hydrogen sulfide leaks, so unified power-off control of precision instruments is required.

[0039] In view of this, in the embodiments of the present application, an intelligent power supply system for an on-board laboratory is provided, which includes an input module, a power supply module, an energy storage module, and an output module; wherein, the input module includes an input circuit breaker and a first isolation transformer. One end of the input circuit breaker is used to connect to an AC power supply, and the other end of the input circuit breaker is connected to the input end of the first isolation transformer; the power supply module includes a rectification circuit and an inversion circuit. The input end of the rectification circuit is connected to the output end of the first isolation transformer, and the output end of the rectification circuit is connected to the energy storage module and the inversion circuit; the output module includes an output circuit breaker, a second isolation transformer, and multiple output branches; one end of the output circuit breaker is connected to the output end of the inversion circuit, the other end of the output circuit breaker is connected to the input end of the second isolation transformer, the output end of the second isolation transformer is connected to each of the output branches, and a sub-circuit breaker is provided in each of the output branches, and each of the output branches is used to supply power to the on-board laboratory equipment. The power supply system in the present application can achieve highly reliable power supply, facilitate the management of the energy of the ship laboratory equipment, and provides a multi-level protection mechanism, which is beneficial to the stable and efficient operation of the ship laboratory equipment.

[0040] In the embodiments of the present application, an intelligent power supply system for an on-board laboratory is provided. It is a highly integrated and intelligent power management solution, designed specifically for laboratory scenarios on ships or offshore mobile platforms. It meets the power usage requirements of complex scientific research equipment by dynamically monitoring, allocating, and optimizing power resources, while adapting to the special challenges of the marine environment. In the embodiments of the present application, there are no restrictions on the specific application scenarios of the intelligent power supply system for the on-board laboratory, and it can be applied to various ships.

[0041] Please refer to Figure 1 , Figure 1The single-line system schematic diagram of an intelligent power supply system for an on-board laboratory provided in an embodiment of the present application is shown. The intelligent power supply system for an on-board laboratory in the embodiment of the present application includes:

[0042] an input module, a power supply module, an energy storage module, and an output module;

[0043] Among them, the input module includes an input circuit breaker and a first isolation transformer. One end of the input circuit breaker is used to connect to an AC power supply, and the other end of the input circuit breaker is connected to the input end of the first isolation transformer;

[0044] The power supply module includes a rectification circuit and an inversion circuit. The input end of the rectification circuit is connected to the output end of the first isolation transformer, and the output end of the rectification circuit is connected to the energy storage module and the inversion circuit;

[0045] The output module includes an output circuit breaker, a second isolation transformer, and multiple output branches; one end of the output circuit breaker is connected to the output end of the inversion circuit, the other end of the output circuit breaker is connected to the input end of the second isolation transformer, the output end of the second isolation transformer is connected to each of the output branches, a sub-circuit breaker is provided in each output branch, and each of the output branches is used to supply power to on-board laboratory equipment.

[0046] In the embodiment of the present application, the main functional modules of the intelligent power supply system for an on-board laboratory may include an input module, a power supply module, an energy storage module, and an output module, but are not limited thereto. Among them, the input module can be used to receive the power input from the outside and provide it to the power supply module. The power supply module is used to perform corresponding processing and energy storage operations on the input electric energy, and distribute it to the energy storage module and the output module. The output module can supply the electric energy in the power supply module or the energy storage module to the on-board laboratory equipment that needs to use electric energy.

[0047] Specifically, in the embodiment of the present application, the input module of the intelligent power supply system for an on-board laboratory is the power inlet of the entire system, responsible for safely and stably connecting to an external AC power supply (such as the ship's main power grid or shore power), and performing preliminary isolation, protection, and filtering processing to ensure the safe operation of the subsequent power supply module and on-board laboratory equipment. Inside the input module, there is an input circuit breaker and an isolation transformer, and the isolation transformer here is denoted as the first isolation transformer. The input circuit breaker, as the main switch of the system, can be used to control the on / off of the external AC power supply. It can provide overload and short-circuit protection to prevent abnormal currents (such as surges, short circuits) from damaging the backend equipment. Generally speaking, the input circuit breaker can adopt a high breaking capacity (HRC) circuit breaker to adapt to the possible high short-circuit current of the ship's power grid. In the embodiment of the present application, the input circuit breaker and other subsequent circuit breakers can be remotely controllable circuit breakers, which is convenient for quickly cutting off the power supply in case of emergency.

[0048] In the embodiment of the present application, the first isolation transformer can achieve electrical isolation between the ship's power grid and the power supply system of the on-board laboratory, preventing common-mode noise and voltage fluctuations from affecting precision instruments. At the same time, the first isolation transformer can also appropriately adjust the input voltage to meet the requirements of on-board laboratory equipment and reduce possible high-frequency interference. In terms of the connection relationship, one end of the input circuit breaker is used to connect to the AC power supply, the other end of the input circuit breaker is connected to the input end of the first isolation transformer, and the output end of the first isolation transformer is connected to the power supply module. The specific form of the input AC power supply is not limited in the present application, and it can be flexibly selected according to actual needs.

[0049] In the embodiment of the present application, the power supply module is the core power conversion and distribution hub of the on-board laboratory intelligent power supply system, responsible for rectifying, energy storage management of the alternating current (AC) provided by the input module, and converting it into a stable alternating current (or direct current) power supply suitable for laboratory equipment according to the load demand. Its core includes a rectifier circuit and an inverter circuit, and works in coordination with the energy storage module to ensure the continuity, stability, and efficiency of power supply.

[0050] Specifically, in the embodiment of the present application, the power supply module includes a rectifier circuit and an inverter circuit. Among them, the rectifier circuit can convert the input alternating current into direct current for storage in the energy storage module or directly supply to the DC load. Exemplarily, in the embodiment of the present application, when converting the alternating current, PWM (pulse width modulation) or PFC (power factor correction) technology can be used to improve the conversion efficiency and reduce harmonic pollution. For the specific structure of the rectifier circuit, it can be implemented with reference to the prior art, and the present application does not limit this. The inverter circuit can convert the direct current output by the energy storage module or the rectifier circuit back into alternating current for use by on-board laboratory equipment. It supports pure sine wave output to ensure that relevant precision instruments (such as spectrometers, PCR instruments) are not affected by waveform distortion. Similarly, the present application does not limit its specific circuit structure.

[0051] In the embodiment of the present application, the alternating current provided by the input module is converted into direct current by the rectifier circuit. One part is supplied to the inverter circuit, and the other part is stored in the energy storage module; when the ship's power grid fluctuates or is interrupted briefly, the energy storage module can release the stored electrical energy to maintain the uninterrupted operation of the system. Generally speaking, the energy storage module can include multiple groups of storage batteries, such as Figure 2 As shown, multiple groups of storage batteries can be placed in the energy storage module to store and release relevant electrical energy through the storage batteries. The direct current is converted into stable alternating current through the inverter circuit and distributed to each on-board laboratory equipment through the output module. In this process, the system can monitor the load demand in real time, dynamically adjust the rectification and inversion power, and achieve the optimal energy efficiency.

[0052] For the output module, it is the terminal power distribution and protection unit of the intelligent power supply system for the shipborne laboratory, responsible for safely and reliably distributing the rectified and inverted electrical energy to each laboratory device. Through multi-level electrical isolation, intelligent circuit breaker protection, and refined branch management, this module ensures that experimental equipment with different power levels and sensitivities obtains stable and clean power supply. It includes an output circuit breaker, a second isolation transformer, and multiple output branches. Among them, the output circuit breaker serves as the main switch of the output loop, controlling the electrical connection between the inverter circuit and subsequent equipment and providing primary protection against overload / short circuit. The second isolation transformer can be used for secondary electrical isolation and secondary voltage adaptation, eliminating high-frequency switching noise of the inverter and achieving physical isolation between the ground wires of shipborne laboratory equipment and the main power grid of the ship.

[0053] In the embodiments of this application, the number of output branches of the output module can be arbitrary. For example, it can be set to 50 or more arbitrary numbers, and a certain number of spare load switches are reserved. On each output branch, a sub-circuit breaker is provided. The sub-circuit breaker is the core component for achieving precise equipment-level protection in the output module, providing independent overload, short circuit, and leakage protection for each output branch to ensure the safe operation of various types of equipment in the shipborne laboratory (from precision instruments to high-power devices). Specifically, for each sub-circuit breaker, it can include functions such as overload protection, short circuit protection, leakage protection, and remote control. This application places no restrictions on this.

[0054] In the embodiments of this application, the types of shipborne laboratory equipment can be flexibly selected according to actual needs. For example, it can include at least one of a core comprehensive testing system, a scanner, a collector, a spectrometer, a magnetometer, a microscope, a diffractometer, a mass spectrometer, and an analyzer.

[0055] It can be understood that an intelligent power supply system for a shipborne laboratory provided in an embodiment of the present application includes an input module, a power supply module, an energy storage module, and an output module. Among them, the input module includes an input circuit breaker and a first isolation transformer. One end of the input circuit breaker is used to connect to an AC power supply, and the other end of the input circuit breaker is connected to the input end of the first isolation transformer. The power supply module includes a rectification circuit and an inversion circuit. The input end of the rectification circuit is connected to the output end of the first isolation transformer, and the output end of the rectification circuit is connected to the energy storage module and the inversion circuit. The output module includes an output circuit breaker, a second isolation transformer, and multiple output branches. One end of the output circuit breaker is connected to the output end of the inversion circuit, the other end of the output circuit breaker is connected to the input end of the second isolation transformer, and the output end of the second isolation transformer is connected to each output branch. A sub-circuit breaker is provided in each output branch, and each output branch is used to supply power to the shipborne laboratory equipment. The power supply system in the present application can achieve highly reliable power supply, facilitate the management of the energy of the shipborne laboratory equipment, and provide a multi-level protection mechanism, which is beneficial to the stable and efficient operation of the shipborne laboratory equipment.

[0056] Specifically, in some embodiments, the input module includes a first input line, a second input circuit, and a selection switch.

[0058] In the embodiments of the present application, the input module of the intelligent power supply system for the on-board laboratory can adopt dual-channel input, including a first input line, a second input circuit, and a selection switch. Through two sets of independent input lines + intelligent selection mechanism, seamless switching between the main / backup power supplies can be achieved. Among them, the first input line includes a first input circuit breaker, the second input line includes a second input circuit breaker, and the first ends of the first input circuit breaker and the second input circuit breaker are used to access different AC power supplies. The first input line can be a three-phase three-wire AC 380v, 50Hz power input; the second input line can be a three-phase four-wire 380V, 50Hz power input. The first input line is the main circuit, and the second input line is the bypass circuit. The selection switch can be used to select to connect the second end of the first input circuit breaker or the second end of the second input circuit breaker to the input end of the first isolation transformer. In this way, when the main circuit fails, the input can be switched to the bypass circuit. Under normal circumstances, the bypass circuit is only used for maintenance, providing a maintenance bypass function, and the output is three-phase four-wire, and the neutral point is required to be connected to the ship's hull (grounded).

[0059] In the embodiments of the present application, the energy storage module can be configured with maintenance-free nickel-cadmium batteries, equipped with battery mounting racks.
