1. Core definition and design positioning

The vehicle-mounted shelter integrated power distribution power unit is different from ordinary civilian power distribution equipment. Its core positioning is motorization, integration, high reliability, and duty-free. Ordinary power distribution boxes only have simple power distribution functions, while this unit is a complete micro power system that can realize multi-power compatible input, refined power processing, intelligent load distribution, independent fault protection and remote monitoring.

Its core design goals are to get rid of dependence on fixed power grids, adapt to all working conditions such as vehicle travel, parking in the field, and sudden power outages, solve core pain points such as AC and DC hybrid power supply for vehicle-mounted shelters, power matching of multiple devices, power safety in harsh environments, and uninterrupted power supply, meet national military standards for environmental adaptability and electromagnetic compatibility, and adapt to the standardized power distribution needs of various special vehicle-mounted shelters.

2. Overall structure and core components

The power supply unit adopts a modular integrated design. The chassis is a reinforced integrated structure with high protection level, anti-vibration and bump resistance, and is suitable for vehicle-mounted maneuvering conditions. The whole unit can be divided into seven core modules, and each module cooperates to complete the full-process power supply operation.

2-1. Multi-source input switching module

As a power access port, it supports seamless access to multiple power sources, covering four major power supply sources: three-phase/single-phase mains (380V/220V), vehicle-mounted silent generator set, vehicle-mounted chassis power supply, and backup battery pack. It is equipped with an industrial-grade waterproof aviation socket (IP67 high protection), adapting to complex wiring environments in the wild. The module has a built-in intelligent switch, which can realize automatic selection and locking control of multiple power sources, and switch between different power supply modes without interruption, preventing power supply flash interruptions from damaging precision equipment.

2-2. Power conversion and voltage stabilization module

The core power processing unit integrates AC/DC rectification, DC/AC inverter, voltage adaptive adjustment, and phase balance functions to achieve bidirectional conversion of AC and DC power. It can convert unstable generator and battery power into standard 220V AC, 48V/24V DC regulated power supply required for in-cabin equipment, adapting to the voltage requirements of different equipment such as communications, radar, industrial control, etc., while automatically correcting voltage deviations and balancing three-phase current to avoid voltage fluctuations damaging load equipment.

2-3. UPS uninterruptible power supply module

The core guarantee of emergency power supply adopts a double-conversion online UPS architecture and is equipped with a large-capacity energy storage battery pack. When the mains power is interrupted, the generator set starts or stops, or the power is switched, seamless power resumption can be achieved in milliseconds without power supply breakpoints. Under normal configuration, the independent battery life can reach 30 minutes to 2 hours. In high-reliability scenarios, it can be equipped with dual hot backup power supplies with a switching time of less than 5 milliseconds, fully ensuring that key precision equipment such as command and monitoring will not go down.

2-4. Intelligent power distribution output module

Responsible for the refined distribution of electric energy, it adopts a multi-channel independent output circuit design to distinguish different power channels such as high-power power loads, precision instrument loads, and lighting auxiliary loads. Each circuit is independently configured with switch control, supports free switching of single-phase/three-phase power distribution, is compatible with multiple specifications of electrical equipment, and can automatically distribute power according to load power to avoid single-channel overload and power waste, and adapts to the simultaneous operation needs of multiple equipment in the cabin.

2-5. Security protection module

The whole machine integrates full-dimensional electrical protection functions, which is the core barrier for the safety of equipment and personnel. It has AC input over-voltage, over-current, short circuit, and leakage detection and protection functions. It also integrates ground detection alarm, high-voltage intrusion protection, and lightning surge protection functions. Built-in three-level lightning protection devices and EMI electromagnetic filters can effectively suppress vehicle electromagnetic interference and outdoor lightning impacts, meet electromagnetic compatibility standards for special equipment, and prevent electromagnetic interference from affecting the operation of precision equipment.

2-6. Status monitoring and control module

Equipped with an intelligent main control unit and high-precision sensors, it can collect input and output voltage, current, power, frequency, battery power, equipment operating temperature and other core parameters in real time. It supports local screen visual display, one-click parameter setting, and reserves Ethernet and CAN bus communication interfaces to upload operating data to the cabin master control system to achieve remote monitoring, fault alarms, data traceability, and supports unattended operation mode.

2-7. Reinforced protective structure module

The whole machine adopts a closed reinforced chassis design, which is anti-seismic, anti-bump, dust-proof, waterproof, moisture-proof, and salt spray-proof. It can adapt to a wide temperature working environment of -40℃~+70℃, and fully meets the working conditions of vehicle-mounted motor transportation and outdoor complex climates. The overall structure is compact, the wiring is regular, and it is suitable for the limited installation space of the cabin.

3. Core working principle

The vehicle-mounted shelter integrated power distribution power unit adopts closed-loop working logic of multi-source optimization, intelligent switching, voltage stabilization and purification, hierarchical power distribution, and full protection. The entire process is automated and does not require frequent manual intervention. The specific operation process is divided into four steps:

3-1. Preferred power access: By default, the system prioritizes access to stable mains power. When there is no mains power, it automatically switches to the vehicle-mounted generator set for power supply. It can switch the vehicle-mounted chassis power supply during maneuvering. In the event of a sudden power outage, it automatically starts the UPS battery emergency power supply to achieve intelligent priority scheduling of multiple power sources.

3-2. Electric energy purification processing: The incoming original electric energy is filtered, stabilized, rectified/inverted to eliminate voltage fluctuations, clutter interference, and electromagnetic noise, and output high-precision, pure standard electric energy to meet the power supply needs of precision electronic equipment.

3-3. Hierarchical intelligent power distribution: The processed standard electric energy is distributed through multiple independent circuits to various loads such as cabin command systems, communication equipment, monitoring instruments, lighting, air conditioners, etc. as needed to achieve accurate power matching and eliminate overload and no-load losses.

3-4. Real-time monitoring and protection: Real-time monitoring of electrical parameters and equipment status throughout the entire operation. Once overvoltage, overload, leakage, short circuit, grounding abnormality and other faults occur, the power will be automatically cut off immediately for protection. At the same time, an audible and visual alarm will be issued and fault information will be uploaded. Normal power supply will be automatically restored after the fault is eliminated.
