Performance requirements matching: Determine processor performance, memory capacity and hard disk storage requirements based on the running software and application scenarios. If you run complex industrial control software or perform big data processing, you need a high-performance processor (such as Core i7 and above), large-capacity memory (8GB and above) and high-speed solid-state drive (SSD); simple data acquisition and monitoring, and a lower-performance processor and a smaller memory configuration can be used. Reliability considerations: The industrial environment has high requirements for computer reliability, and choose an industrial-controlled computer with wide temperature design (accommodating to -20℃ to 60℃ or even wider temperature range), vibration resistance, dust resistance, moisture resistance and other characteristics. At the same time, pay attention to its power supply stability and electromagnetic compatibility (EMC) to ensure stable operation in complex electromagnetic environments. Extensibility evaluation: Considering future system upgrades and functional expansion needs, select industrial control computers with rich expansion interfaces (such as PCI, PCI - Express slots) and expandable memory slots, which are convenient for adding data acquisition cards, motion control cards, graphics cards and other equipment to meet the diverse needs of different industrial applications. Interface type and quantity: According to the connected external devices, ensure that the industrial control computer has corresponding interfaces, such as RS-232/485 serial port (used to connect sensors, instruments, etc.), USB interface (connecting printers, storage devices, etc.), Ethernet port (realizing network communication), etc., and the number of interfaces meets the actual needs. Operating system compatibility: Make sure that the industrial control computer supports the required operating systems, such as Windows Embedded, Linux, etc., to ensure that the operating system is well compatible with the running software and hardware drivers, and to ensure the stable operation of the system.
