AEG A127-029-081-942 PCB CARD is a prefabricated circuit board used in ship electronic systems. It realizes specific functions by integrating electronic components and is the core component of ship electrical systems. It has a wide range of uses, covering navigation, power control, communication, safety monitoring and other fields, providing support for the automated and intelligent operation of ships. For example, in the ship navigation system, the PCB module is responsible for processing data from radar, GPS and other equipment to ensure navigation safety; in the power system, it controls the start, speed regulation and fuel management of the engine to improve operating efficiency.
Main components and functions
Base material: The module is made of glass fiber or epoxy resin, providing mechanical support and insulation functions.
Conductive layer: Made of copper foil, it is responsible for transmitting current and signals to achieve electrical connections between electronic components.
Solder mask: Protects the copper foil of the circuit board from oxidation and prevents short circuits.
Character layer: Marks the position of components on the circuit board for easy assembly and maintenance.
Functions
Control function: The ship PCB module adjusts the engine power, pump start and stop, valve switch, etc. through precise control signals to ensure that the ship equipment operates on demand. For example, when the ship accelerates, the module can automatically adjust the fuel supply to optimize the power output.
Monitoring function: The module collects temperature, pressure, liquid level and other data in real time through sensors, and transmits the information to the control center. For example, when the engine temperature is abnormal, the module will trigger the alarm system to prompt the crew to take measures.
Communication function: The module supports data interaction between ships and external equipment, such as navigation systems, radars, satellite communications, etc. For example, in complex sea conditions, the module can ensure that radar data is seamlessly connected with the automatic collision avoidance system to improve navigation safety.
Power management: Support power distribution and monitoring to ensure the stable operation of the power system.
Integrated design: Modular design supports multi-functional integration and simplifies installation and maintenance. For example, in a fire alarm system, the PCB module monitors smoke or temperature abnormalities through sensors, triggers alarms in time and starts fire extinguishing devices.
Design principles and features of ship PCB modules
The design of ship PCB modules must meet the requirements of high reliability and resistance to harsh environments. It adopts moisture-proof, salt spray-proof, and vibration-proof designs and complies with international standards (such as IEC and DNV-GL). Its features include:
Integration and modularization: Integrate multiple functions into a single circuit board to save space and simplify the installation process.
Intelligence and automation: Support automatic control and remote monitoring, reduce manual intervention, and improve operating efficiency.
Standardization and compatibility: Comply with international standards, can be seamlessly connected with other ship systems, and reduce integration costs.
Safety and redundancy design: With fault diagnosis and redundancy design, ensure that key functions can still operate normally under abnormal conditions. For example, dual power supply or dual communication interface design is adopted to improve the fault tolerance of the system.
Application scenarios
Power system: Ship PCB modules are used to control the start-up, speed regulation and fuel management of the engine, while monitoring parameters such as exhaust temperature and vibration to ensure efficient operation of the power system. For example, during the main engine speed regulation process, the module can accurately control the fuel injection amount and reduce energy consumption.
Navigation and safety system: The module is integrated into GPS, radar, AIS and other equipment to provide information such as heading, location, obstacles, etc., and supports automatic collision avoidance. For example, when sailing at night, the module can process radar data in real time to assist the crew to avoid risks.
Power system: The module is responsible for power distribution and monitoring to ensure voltage and current stability and prevent overload or short circuit. For example, during peak power demand, the module can automatically switch to backup power to ensure power supply for key equipment.
Environment and safety monitoring: The module monitors the air quality, temperature and humidity in the cabin, as well as hidden dangers such as fire and flooding, triggers alarms and initiates emergency measures. For example, when smoke is detected, the module immediately shuts down the ventilation system and activates the fire extinguishing device.
Life and entertainment system: The module supports intelligent control of air conditioning, lighting, and entertainment equipment to improve the comfort of crew and passengers. For example, on a cruise ship, the module can realize personalized adjustment of guest room lighting and temperature.
Advantages
