However, current power distribution management systems still rely on individual controllers to control these devices, requiring operators to manually turn them on or off. This method is not only labor-intensive but also demands a high level of familiarity with the modular shelter system from the operators, and the system integration is not ideal. Furthermore, with the increasing number of devices within the modular shelter, the number of independent circuit breakers for each device also increases, leading to space constraints within the power distribution box and further increasing system complexity. Existing manual circuit breaker operation methods are cumbersome and inefficient, undoubtedly increasing operational complexity and, to some extent, wasting human resources. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] To better understand the above technical solution, the following will provide a detailed explanation of the technical solution in conjunction with the accompanying drawings and specific testing methods.

[0028] Example 1

[0029] Reference Figure 1 As shown, this utility model provides an on-board power distribution management system, comprising:

[0030] The power module is connected to an external power source; the power module includes a conversion module, a bypass unit, and a power distribution monitoring unit; the conversion module is connected to the bypass unit and the power distribution monitoring unit; the bypass unit is connected to the power distribution monitoring unit; the power distribution monitoring unit is connected to the electrical equipment.

[0031] The power distribution unit is connected to the power module; the power distribution unit includes an uninterruptible switching device and a digital signal processor, with the uninterruptible switching device connected to the digital signal processor.

[0032] A centralized controller is connected to the power supply module and the power distribution unit.

[0033] Specifically, refer to Figure 2 As shown, the conversion module includes an AC / DC module, a DC / DC charging module, a DC / AC module, and a DC / DC module. The connections between the modules are as follows: the AC / DC module connects to the DC / DC module and the bypass unit; the DC / DC charging module connects to the external battery and the DC / DC module; the DC / AC charging module connects to the bypass unit and the external battery; and the DC / DC module connects to the power distribution monitoring unit. Specifically, the AC / DC module converts AC power to DC power to supply the bypass unit and the DC / AC module. The DC / DC charging module charges the external battery and also powers the DC / DC module. The DC / AC module converts DC power to AC power to supply the power distribution monitoring unit. The DC / DC module adjusts the voltage to power the power distribution monitoring unit.

[0034] Specifically, the bypass unit allows for direct power supply, bypassing certain modules when needed. The power distribution monitoring unit, as the core control unit, receives power from the AC / DC module, DC / DC module, and DC / AC module. It also monitors and distributes power to different electrical devices.

[0035] Specifically, the power output from the power distribution monitoring unit can be used to supply power to 6 channels of electrical equipment via AC220V; to 9 channels of electrical equipment via DC24V; and to the power strips in the first and second cabinets via AC220V and DC24V respectively. Each power strip has filtering and protection functions, and then the power is distributed to the distribution unit. Specifically, refer to... Figure 2 The DC 24V supply powers three DC output branches, which may be used for remote control or to power devices that require DC power. The AC 220V supply powers three DC output branches, which may be used for remote control or to power devices that require DC power.

[0036] Furthermore, the power module also includes a protection submodule, which connects to the bypass unit and the conversion module, and provides protection against current flowing to these two modules when power is input to the power module. Specifically, the protection submodule includes three main functions: lightning protection, surge protection, and overcurrent protection, to ensure the safety and stability of the power module under various abnormal conditions. In addition, the power module is designed with an interface for connecting to external power sources, allowing it to flexibly connect to different types of power supplies. These external power sources include mains power, batteries, and power take-off generators, thereby improving the adaptability and reliability of the power module.

[0037] Specifically, for the uninterruptible switching device in the power distribution unit, its function is to automatically switch between mains power and the inverter to ensure the continuity of power supply. (Refer to...) Figure 3 When the mains power is normal, the system prioritizes using mains power; when the mains power is interrupted, the system automatically switches to inverter power supply. Power distribution and monitoring are achieved through control by a digital signal processor (DSP). The uninterruptible switching device is connected to the DSP via an I / O interface, which is used for inputting and outputting signals, enabling communication and control with external devices. Multiple control signals issued by the DSP can be used for remote control or monitoring of various parts of the power distribution unit.

[0038] Specifically, the centralized controller is responsible for monitoring and controlling the entire system, communicating with the power distribution monitoring unit to ensure stable system operation. The centralized controller includes a priority processing unit connected to a digital signal processor (DSP). The main function of the priority processing unit is to prioritize tasks and operations, ensuring that critical tasks are executed first. This design significantly improves the system's processing efficiency and response speed. Through the collaborative work of the priority processing unit and the DSP, the centralized controller can more intelligently allocate power resources and optimize power supply strategies. This intelligent control mechanism is particularly important when facing complex power demands and changing system states. It not only ensures the stability of power supply but also improves the reliability and flexibility of the entire system. Furthermore, this design of the centralized controller facilitates more refined power management and more efficient fault handling. When an anomaly or fault occurs in the system, the priority processing unit can quickly identify the problem and make rapid decisions through the DSP, taking corresponding control measures, such as adjusting power distribution or switching power sources, to minimize the impact of the fault on the system.

[0039] Specifically, the circuit of the system described in this embodiment includes fuses and circuit breakers, which can be referred to as follows. Figure 4 As shown in the diagram, the circuit breaker (Q1), fuse, rectifier, diodes (D1 and D2), and grounding symbol (PE) are included. The fuse is primarily used to automatically disconnect current in the event of an overload or short circuit, protecting the circuit from damage. The circuit breaker, on the other hand, can quickly disconnect the power supply upon detecting abnormal current, preventing further electrical accidents. The proper configuration of these two protective devices ensures the safe operation and reliability of the system.

[0040] Furthermore, the system provided in this embodiment also includes a display, an industrial control computer, a power button, indicator lights, a buzzer, a residual current device (RCD), a battery switch, and a mains circuit breaker switch. The display is connected to the centralized controller and includes an industrial control panel power supply interface, a program download port, and a communication interface. The indicator lights include power-on and running status indicators; the mains circuit breaker switch is connected to the circuit breaker in the circuit.

[0041] The specific usage method and working principle of the power distribution management system provided in this embodiment are as follows:

[0042] Step 1: Manual Start-up. Ensure that any of the following power sources is connected: 220V AC mains, 28V DC generator, or 24V DC battery. Close the leakage protection device. Rotate the battery input switch to the "ON" position to supply power to the battery. Click the "Power On" button. The power-on indicator light (white light) on the display panel will illuminate, the system will start, the industrial control computer interface will be displayed, and the equipment will enter self-test mode. During the self-test, the running status indicator lights (red and blue) will flash alternately, and the output status indicator lights will illuminate sequentially. After the self-test is complete, the buzzer will emit a short "beep". If the self-test is normal, the running status indicator light will turn green.

[0043] Step 2: The main interface of the industrial control computer displays the topology diagram of the various modules, units, or interfaces in the integrated power system. The power distribution unit table on the right displays the load power and status of the DC and AC output interfaces in real time. Interface status is indicated by color: on (green), off (red). The upper part of the main interface also includes:

[0044] 1. Battery Identifier: The battery identifier can display the status of the system battery in real time. When the battery is charging, the battery identifier is green and has a lightning bolt symbol, otherwise there is no lightning bolt symbol. When the battery is disconnected from the integrated power system, the battery identifier turns colorless and continues to flash until the battery is normally connected to the system. When the battery voltage is lower than 19V, the battery identifier turns red and the industrial control computer pops up a message "Battery voltage is low".

[0045] 2. Signal bar indicators: There are a total of 5 signal bar indicators, each representing one communication channel, namely: AC / DC, DC / DC, DC / AC, charging module, power distribution board module, etc. If a communication channel is disconnected, a white signal bar will be displayed.

[0046] 3. Fan indicator: When the fans on the integrated power supply are running normally, the white "fan indicator" on the industrial control computer will rotate dynamically; when all fans stop, the white "fan indicator" will also stop; if one or more fans on the chassis stop due to a fault, a pop-up alarm will immediately appear on the industrial control computer interface: "Fan fault", accompanied by a buzzer alarm sound.

[0047] 4. Alarm light indicator: Under normal operating conditions, the alarm light indicator on the industrial control computer interface will be green. When a system fault occurs, the alarm light indicator will be red and accompanied by a buzzer alarm sound. At this time, the system should be stopped immediately and the cause of the alarm should be checked.

[0048] Furthermore, the output status monitoring interface includes an AC output monitoring column (left) and a DC output monitoring column (right). Each channel can display its switch status, voltage, current, and power. When a channel is open, the switch status column displays "On," and the voltage, current, and power columns all display the actual voltage, current, and power values. The single-channel power output protection setting interface is divided into AC and DC columns. The left column shows the AC single-channel power output protection settings, and the right column shows the DC single-channel power output protection settings. It is recommended that each channel's output power protection value be set to 10% of its rated power. For example, if the rated power is 3000W, the protection value can be set to 3300W. Of course, the single-channel power protection value can also be set according to the user's actual needs. In the system protection parameter setting interface, parameters can be modified, but arbitrary changes are not recommended. If the user needs to modify preset parameters, they can press and hold the corresponding parameter box for 2-3 seconds, wait for the pop-up numeric keypad, enter the administrator password: 123456, and then click the "OK" button to modify the parameters. This interface features a one-click factory reset function. To do this, click the "Restore Factory Settings" button, enter the password: 654321, and click the "OK" button. The historical alarm interface displays 8 alarm messages per page, including time (year, month, day, hour, minute, second) and event type. This interface can store a maximum of 88 messages; newer events overwrite older messages when full. Users can view messages using the "Previous Page," "Next Page," "First Page," and "Last Page" buttons. The power supply priority and uninterruptible power supply (UPS) selection settings interface allows setting the priority of AC (AC220V) and DC (DC24V) output channels. There are 8 AC output channels with 8 priority levels (lower numbers indicate higher priority); there are 9 DC output channels with 9 priority levels. Users can modify the priority level of either AC or DC output channels according to their needs. The UPS selection is "On" or "Off." When "On," it automatically switches to UPS mode if the mains power or generator connection fails.

[0049] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0050] The system described in this embodiment is centrally managed to ensure a stable power supply and reasonable distribution. Simultaneously, the system incorporates multiple protection measures, such as lightning protection, surge protection, and overcurrent protection, to enhance system safety and reliability. Through digital signal processor control, the system achieves efficient power distribution and real-time monitoring, further enhancing power supply stability. The introduction of an uninterruptible switching device enables a smooth transition between mains power and inverter power, ensuring continuous power supply to critical loads and improving power continuity. The system provided in this embodiment is easy to operate and highly integrated.

Therefore, this embodiment solves the problems of limited space resources, low integration, and wasted human resources caused by equipping each device with an independent circuit breaker. It achieves centralized power distribution control for each device, optimizes space layout, improves system integration, and thus reduces the waste of human resources.
