Introduction: Redefining the human-machine interaction between ships and industry
In modern ship driving, power positioning, and industrial power generation systems, the information exchange interface (HMI) between operators and equipment has become a key determinant of system availability, safety, and efficiency. Although traditional indicator lights, buttons, and analog instruments are reliable, they can no longer meet the increasingly complex needs of data visualization, alarm management, remote monitoring, and trend analysis. An advanced, intuitive, and robust graphical interface that can integrate dispersed controller data into actionable situational awareness, significantly improving decision-making efficiency and fault response speed.
The DEIF AGI 400 series advanced graphical interface was born for this purpose. As a professional HMI solution designed for maritime and harsh industrial environments, the AGI 400 series not only has excellent hardware reliability and visual performance, but also is equipped with an open software platform based on Linux RT, supporting rich communication protocols and powerful data processing capabilities. Whether used for energy monitoring systems (SEMS), generator set power management (PMS), or as a local operation station for mechanical/electrical systems, AGI 400 offers a comprehensive selection from 7 inches to 21.5 inches. This article will deeply analyze the technical architecture, core functions, and application value of the AGI 400 series, helping engineers make optimal decisions in project selection and system integration.
Hardware Platform: A sturdy touch terminal designed for harsh environments
The AGI 400 series includes four models: AGI 407 (7 inches), AGI 410 (10.1 inches), AGI 415 (15.6 inches), and AGI 421 (21.5 inches). Although the screen sizes vary, the entire series shares a unified high standard hardware design concept, ensuring stable operation under any working conditions.
1. Display and Touch Control
High definition widescreen display: All models use TFT color LCD screens, supporting 24 bit color (16 million colors), and color reproduction is realistic. The resolution ranges from 800 × 480 (AGI 407) to Full HD 1920 × 1080 (AGI 421), presenting delicate vector graphics and dashboard elements.
High brightness and wide viewing angle: AGI 407/410 has a brightness of 500 cd/m ², AGI 415 has 400 cd/m ², and AGI 421 has 300 cd/m ², ensuring clear readability even under direct sunlight or high ambient light conditions. The horizontal/vertical viewing angles are both above 170 °, meeting the needs of observing from different angles.
Projection capacitive multi touch: supports multi touch gestures such as sliding, pinching, and zooming, providing an operating experience comparable to modern mobile devices. The touch screen is sturdy and durable, and can withstand frequent operations.
Flexible dimming and energy saving: The backlight brightness can be continuously adjusted from 0 to 100%, and supports custom timeout shutdown to extend the LED backlight life (typical life>50000 hours). This is particularly important for night navigation or low light environments.
2. Core computing and storage
Processor: AGI 407/410 adopts ARM Cortex-A9 dual core 800MHz; AGI 415/421 upgraded to quad core Cortex-A9 800MHz, ensuring smooth rendering and multitasking of complex images.
Memory and Storage: Equipped with 1GB DDR (407/410) or 2GB DDR (415/421) operating memory, as well as 4GB or 8GB flash memory as user storage space, and integrated 64KB FRAM (ferroelectric memory) for power down retention of critical data, it can be saved persistently without the need for batteries.
Operating System: Adopting Linux RT (real-time) operating system, it ensures the system's deterministic response and long-term stability, away from the license and virus troubles of Windows system.
3. Interface and Expansion Capability
Network: Equipped with 3 independent Ethernet ports (2 × 10/100Mbit+1 × 10/100/1000Mbit), each port has an independent MAC address and supports bridging mode, making it easy to build redundant networks or isolate different network segments.
USB: 2 USB 2.0 host ports that can be connected to keyboards, mice, USB drives, or Wi Fi adapters.
Serial communication: Provides RS-232, RS-485, RS-422 three in one serial port, which can be configured through software and is compatible with various old devices.
Expansion slot: 2 optional plug-in modules, such as CANopen/J1939 communication module (EXM CAN) or digital I/O expansion module (EXM AGIO-06), to meet special protocol or small I/O point requirements.
SD card slot: used for data recording, project backup, or firmware upgrade.
4. Power supply and environmental adaptability
Wide voltage DC power supply: supports 10~32V DC, suitable for common 24V power systems in ships and industrial sites, and has automatic self recovery insurance.
Wide temperature range: When installed vertically, the working temperature is -20 ℃~+60 ℃ (-20 ℃~+50 ℃ with expansion module or USB device), and the storage temperature is -30 ℃~+70 ℃, fully meeting the requirements of marine and outdoor cabinets.
