Core Tip: Embedded industrial computer technology is one of the most popular and promising IT application technologies at present. It is widely used in industrial computer products and has become the development trend of the industrial control industry. The advantages of embedded, miniaturized, low power consumption, fanless, wide temperature design, and adaptability to harsh working environments make it quickly favored by emerging markets, rewriting the market situation of the traditional rack-mounted industrial computer that dominates the world, allowing industrial control The development of machine technology presents earth-shaking changes.
Embedded technology is one of the most popular and promising IT application technologies at present.

Compared with the traditional industrial computer, the embedded industrial computer is application-centric, based on computer technology, and can be tailored for software and hardware. system. It generally consists of four parts: embedded microprocessor, peripheral hardware device, embedded operating system and user's application program, and is used to realize functions such as control, monitoring or management of other devices. The advantages of embedded industrial computer are mainly reflected in the following aspects:
1. The function of the product has good adaptability, and it almost completely matches the function of the tested and controlled object. It has a certain scalability but does not take expansion as the main purpose, so the product is cost-effective;
2. The miniaturization of the device is one of the main manifestations, which is reflected in the compact design. There is no standard for reference in the structural design. It is necessary to fully consider the rational use of the external interface and installation space;
3. High reliability requirements. On the basis of electrical functions meeting reliability design, reliability design contents such as heat dissipation design, electromagnetic compatibility design, dustproof and waterproof design, and anti-vibration design should be carefully considered;
4. Ultra-low power consumption fanless design is the mainstream. Since the device is miniaturized, the heat dissipation capacity is limited, and the MTBF (mean time between failures) of the embedded system is also very high, especially in unattended applications, ultra-low power consumption fanless design becomes a must.
At present, in the Chinese market, the number of applications of embedded industrial computers far exceeds that of various traditional industrial computers. Military equipment and other industries have been popularized, and the fields of application are extremely broad.
