Description

Technical Field

[0001] The invention relates to an obstacle sound and light lighting system and method for centrally controlling a centralized power supply, belonging to the technical field of marine lighting control. Background Art

[0002] In modern industrial and civil buildings, the sound and light obstacle lighting system plays a vital role. Especially in special environments such as offshore converter stations and offshore work platforms, it not only provides necessary lighting for nighttime or low-visibility environments, but also issues warnings through sound and light signals to ensure the safety of personnel and equipment. Traditional sound and light obstacle lighting systems usually use decentralized power supplies and control methods. Each lighting device or sound and light signal device is equipped with an independent power supply and control unit. This method is relatively simple in system design and installation, but it also has many limitations. In traditional systems, each device is powered independently. Once a power supply fails, the corresponding device will fail immediately. For example, in some key industrial facilities or large buildings, if the power supply of the obstacle light fails, it may cause night workers or aircraft to fail to find obstacles in time, causing safety accidents. When land-based obstacle lighting facilities fail, it is usually easier to replace and repair them, so it may not be necessary to set up a redundant power supply system to ensure their continued operation. However, once the offshore obstacle lighting facilities fail, replacement and repair work will be very difficult due to their remote location, harsh environment and difficulty in maintenance. In addition, marine obstacle lighting is essential to ensure the safety of ship navigation as they help ships avoid potentially dangerous areas and structures.

[0003] The patent document with the patent number "CN115842369A" discloses a modular integrated optical storage device and its control method. The problem with this device is that although the modular design improves the system's integration and expansion convenience, it also means that the system is relatively complex. Modular design requires precise interfaces and control strategies to ensure the coordination between modules, which increases the difficulty of system design and maintenance, especially maintenance operations at sea. At the same time, high integration and intelligence levels may also lead to increased system costs. Summary of the invention

[0057] It should be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0058] The terms “include” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0059] The term "and / or" means and includes any and all possible combinations of one or more of the associated listed items.

[0060] Embodiment 1:

[0061] In this embodiment, the first low voltage AC circuit breaker is Figure 2 As shown in Z1, the second low voltage AC circuit breaker is Figure 2 As shown in Z2, the third low voltage AC circuit breaker is Figure 2 As shown in Z3, the fourth low voltage DC circuit breaker is Figure 2 As shown in Z4, the fifth low voltage AC circuit breaker is Figure 2 As shown in Z5, the sixth low voltage AC circuit breaker is Figure 2 As shown in Z6, the seventh low voltage AC circuit breaker is Figure 2 As shown in Z7, the eighth low voltage AC circuit breaker is Figure 2 As shown in Z8, the ninth low voltage AC circuit breaker is Figure 2 The Z9 shown in the figure has a surge protector of Figure 2 The SPD shown in .

[0062] See also Figure 1-2 , the present invention provides an obstacle sound and light lighting system with centralized control of centralized power supply, including a power supply module, a control module, an energy storage module, a lighting module and a 220V AC bus;

[0063] The output end of the power supply module is connected to the 220V AC bus, the energy storage module is connected to the 220V AC bus, the input end of the lighting module is connected to the 220V AC bus, and the control module is connected to the 220V AC bus;

[0064] The power supply module provides power to the 220V AC bus;

[0065] The energy storage module is used to store and output electrical energy;

[0066] The control module is used to control the energy storage module to store or output electric energy, and to control the lighting module to turn on or off.

[0067] The power supply module includes a power switching device. The main power input terminal is connected to a 220V AC power supply, and the backup power input terminal is connected to a 220V fire power supply. When the main power fails, the power switching device can quickly switch to the backup power supply within 400ms, and allows short-term parallel operation during the switching period to ensure the continuous power supply of the 220V AC bus, greatly improving the reliability of power supply. For example, in some important industrial sites or large buildings, even if the city power is suddenly interrupted, the system can continue to operate stably relying on the fire power supply, ensuring the normal operation of the obstacle sound and light lighting system and avoiding safety accidents caused by power outages.

[0068] The energy storage module uses a lithium iron phosphate battery pack and an inverter. The inverter can convert the AC power input from the 220V AC bus into DC power and store it in the lithium iron phosphate battery pack, and can also invert the DC power of the battery pack into 220V AC output. Based on multi-power redundancy, the energy storage module further enhances the power supply stability of the system. Even in extreme cases where all external power supplies fail, the energy storage module can provide continuous power supply to the system for a certain period of time to ensure that the key sound and light warning functions are not interrupted.

[0069] As a preferred embodiment, the power supply module includes a power switching device;

[0070] The main power input end of the power switching device (the switching time is 400ms, and short-term parallel operation is allowed during the switching period to meet the switching requirements without power outages) is connected to the 220V AC power supply through the first low-voltage AC circuit breaker, and the backup power input end of the power switching device is connected to the 220V fire power supply through the second low-voltage AC circuit breaker;

[0071] The output end of the power switching device is connected to the 220V AC bus.

[0072] The control module includes a controller and a communication circuit, which can centrally control the storage or output of the energy storage module, as well as the opening or closing of the obstacle lights, navigation lights, signal lights and sound signal devices in the lighting module. This centralized control method realizes the unified coordination and linkage of various devices in the system. For example, in an emergency, all sound and light signal devices can be quickly and uniformly controlled to sound an alarm, improving the system's response speed and emergency handling capabilities. At the same time, the scalability and flexibility of the system are also enhanced. When new lighting equipment or signal devices need to be added, they only need to be connected to the 220V AC bus and the corresponding control configuration is performed. There is no need to re-lay the power and control lines, which facilitates system upgrades and expansions.

[0073] As a preferred embodiment, the energy storage module includes a lithium iron phosphate battery pack and a converter;

[0075] If the lithium iron phosphate battery pack is in the state of storing electric energy, the inverter is used to convert the AC power input from the 220V AC bus into DC power output (220V AC power is rectified into 48V DC power). If the lithium iron phosphate battery pack is in the state of outputting electric energy, the inverter is used to convert the DC power input from the lithium iron phosphate battery pack into AC power output (48V DC power is inverted into 220V AC power).

[0076] Although the obstacle sound and light system needs to be powered continuously for at least 4 days, the obstacle sound and light load is small and the required battery capacity is small. Lithium iron phosphate batteries with higher energy density are selected as energy storage batteries to reduce the volume and weight of the obstacle sound and light system distribution box. The battery system is composed of lithium iron phosphate battery cells connected in series, and the nominal voltage after series connection is considered to be 48V DC.
