For convenience of description, some terms or expressions referred to in the embodiments of the present application are explained below:

KVM technology (Keyboard Video Mouse): KVM technology is capable of accessing and controlling a computer quickly and conveniently by connecting a controlled computer keyboard, video or mouse port without providing a separate peripheral device. The KVM technology is a real-time out-of-band management, which means that the controlled terminal can conveniently access the target computer even in the BIOS basic display environment. Compared with the use, the KVM provides real mainboard level access, supports various mainstream platform servers and serial devices at present, is convenient for daily operation and maintenance, and hardly has the compatibility problem.

The KVM switcher: the formal name of a KVM switch is a KVM peripheral switch or KVM switch. The KVM switch is simply a device that allows a system administrator to switch computer peripherals that control multiple servers or computer hosts through a set of KVMs (keyboard, display, and mouse). The switcher can save the expenses of a plurality of KVM peripherals and can facilitate the daily operation of managers. KVM switches are typically used in locations where there are a large number of computer networks and other servers, in which case there is typically only one management Interface (Interface). The price difference between KVM switches from 2 small-sized group interfaces TO 128 large-sized group LAN _ TO _ KVM switches is very large, and currently, most research and development enterprises are gradually oriented TO the development of small embedded single chips due TO the decreasing demand of large-sized KVM switches.

An out-of-band management mode: the Out-of-band Management mode (Out-of-band Management) is relative to the In-band Management mode (In-band Management), and is the most different from the In-band Management mode In that the Out-of-band Management mode does not depend on the support of the self operating system of a computer or a server, does not consider the network condition, the software interface condition and the control terminal software environment required by the In-band Management, and directly controls and displays the basic display environment (including bootloader, bios, serial port echo and the like) of the controlled equipment. The most advantage of out-of-band management is the most direct and convenient maintenance and debugging mode in the emergency disposal states of computer failure, network blockage, equipment initial installation and the like.

The microcontroller MCU: a Microcontroller (MCU), also called as a Micro Controller Unit (MCU). Peripheral interfaces such as a simplified CPU, a memory (memory), a counter (Timer), a GPIO, an ADC, a DAC, a UART, a PLC, a DMA, a USB and the like, even an LCD driving circuit are integrated on a single chip to form a chip-level computer, and different combinations are made for different application occasions to control. Such as mobile phones, PC peripherals, remote controls, to automotive electronics, industrial stepper motors, robotic arm controls, etc., see the silhouette of the MCU.

System on chip SOC: a System on Chip SOC (System on Chip) implements various functional modules such as storage, processing, logic, and interfaces in one Chip, rather than requiring several different physical chips as in a System on board. Compared with an on-board system, the solution of the SOC is lower in cost, can realize faster and safer data transmission between different system units, and has higher overall system speed, lower power consumption, smaller physical size and better reliability.
