II. Core Hardware Configuration Selection Processor Platform: Select the appropriate processor architecture based on the application complexity. Intel platforms (Atom, Celeron, Core i3/i5/i7 industrial-grade versions) offer strong compatibility and are suitable for running Windows systems and traditional industrial control software; ARM platforms (such as RK3399) offer low power consumption and high cost-effectiveness, making them suitable for mid-range applications under the Android system; domestic platforms (such as Zhaoxin and Loongson) meet the requirements for independent control. Memory and Storage: At least 8GB of RAM is required, with 16GB or more needed for complex applications. For storage, SSDs offer faster data access and higher reliability than traditional hard drives, making them more recommended for industrial environments. Based on data caching needs, it is advisable to reserve 20%-30% of capacity as a redundancy. Protection Rating and Durability: IP protection rating is a basic requirement for industrial flatbed trucks. IP65 indicates complete dust protection and the ability to withstand low-pressure water jets, suitable for most indoor industrial environments; IP67 allows short-term immersion in 1 meter of water, suitable for scenarios where washing may occur; IP69K can withstand high-pressure, high-temperature water jets and is designed for extreme clean environments such as food processing and pharmaceuticals. In addition, it is important to check whether the equipment has passed the MIL-STD-810G military standard test to ensure shock and vibration resistance. Wide operating temperature range: Industrial flat panels need to operate stably under extreme temperatures. Mainstream products support operating temperatures from -20℃ to 60℃, while high-end models can reach -30℃ to 70℃. In terms of heat dissipation design, the fanless design is more suitable for dusty environments, avoiding fan blockage that could affect stability. III. Display and Interaction Design Screen characteristics: A high-brightness screen with ≥1000 nits is required for outdoor or bright light environments. Indoor applications typically require 300-500 nits. IPS panels offer a wider viewing angle, suitable for multi-angle viewing scenarios. Touch technology selection: Resistive touchscreens support operation with gloves and wet hands, are highly adaptable and low-cost, but have lower light transmittance; capacitive touchscreens support multi-touch, offer smooth operation, and have a transparency of over 90%, but may be affected by oily or humid environments. For hygienic environments, a nano-silver antibacterial coating is an option. Size matching: Common sizes include 7 inches, 10.1 inches, 12.1 inches, 15.6 inches, 18.5 inches, and 21.5 inches. Mobile inspection is suitable for portable sizes of 7-10 inches, while fixed-installation center consoles are suitable for large screens of 15.6-21.5 inches. IV.
