The shipboard electrical environment has unique characteristics: strong electromagnetic interference, the ship's hull serving as a common ground causing ground potential differences between devices, frequent power supply fluctuations, and harsh environments with humidity and salt spray. For critical equipment (navigation, communications, automation control, and monitoring systems), isolated power supply modules are essential protection measures.

Customer background needs analysis We spoke with a seasoned sailor (Frankie), a boat owner who frequently sails across Europe. He shared his years of searching for a touchscreen suitable for marine use. A devoted user of OpenCPN charting software, he was troubled by the lack of quality screens on the market that were truly suitable for outdoor marine use. Problems with traditional products mentioned by Frankie After years of testing various products, Frank summarized the core problems that existing touch panels face in marine environments: 1. Severe parallax issues - Traditional screens often struggle to accurately control touchscreens in turbulent sea conditions, leading to frequent misoperations. 2. Narrow viewing angle - While the display is accurate from a single viewing angle, it becomes difficult to see the screen content at a distance from the bridge or at other angles, and multi-angle viewing is poor. 3. Inadequate brightness - Many advertisers fail to achieve the brightness they claim, or even significantly undercut it, making the display unreadable even in strong sunlight. 4. Defective dimming function - The dimming function fails to adjust the screen to a comfortable level and can only be adjusted over a wide range, making it insufficient for nighttime use. 5. Multi-touch issues - The screen is unresponsive when wet or with wet hands, resulting in poor operation and misoperation. In severe cases, the screen may even become unusable. 6. Unintelligent brightness adjustment - During unpredictable daytime weather, it would be beneficial if the display had an automatic brightness adjustment feature, which would greatly enhance the user experience and save energy.

Box PC, also named embedded computer, is a compact computer designed for industrial and commercial application. Unlike traditional desktop computers, Box PCs are able to withstand harsh environments, provide greater durability and reliability, and achieve breakthroughs in protection performance, volume control, and application flexibility. They are often used in applications where space is limited and better performance is required, such as automation, manufacturing, and transportation industries. Box PCs are the core of industrial automation systems, providing computility for various application such as data acquisition, machine control, and system monitoring. They are usually equipped with powerful processors and sufficient memory space, and a variety of expansion connection options, which can be seamlessly connected with other industrial equipment. Its compact size and fanless design ensure efficient operation even in small spaces and harsh conditions. Waterproof Box PC is a device designed to operate in environments where it may be exposed to water and other contaminants. They use a rugged aluminum alloy housing with a strict ingress protection (IP) standard IP67. This rating means complete protection against dust intrusion and low-pressure water jets from any direction, ensuring that the device can operate reliably in wet and dusty environments. Waterproof Box PCs are generally used in industries such as manufacturing, food and beverage processing, marine, Industrial Internet of Things (IIoT) or edge computing, which have a growing demand for reliable and durable computing solutions. These industries often operate in environments where traditional computing devices are prone to failure due to exposure to moisture and extreme temperatures. Waterproof Box PCs meet these challenges by providing a resilient solution that can maintain performance and reliability even in the harshest conditions.
