Problems solved by technology

[0005] First of all, the bandwidth of the serial port cannot meet the real-time requirements, and its physical characteristics also determine that the transmission distance is limited, and remote monitoring and management cannot be realized;
[0006] Secondly, it only supports keyboard operation and cannot meet the user's ease of use requirements;
[0007] Finally, due to the use of a single-task system, the data transmission efficiency is not high

Abstract

The invention discloses a realizing method of a virtual screen of an embedded type system, comprising the following step of: drawing the display content of embedded type equipment far to a programming interface of a background for display through an Ethernet. The invention also discloses the embedded type system comprising the embedded type equipment, the Ethernet and the background, wherein the Ethernet is used for drawing the display content of the embedded type equipment far to the programming interface of the background for display. In the embedded type system and the realizing method of the virtual screen thereof, the Ethernet is adopted to substitute a serial port, thereby solving the problem of limited transmission distance caused by the serial port and achieving the effect of remotely controlling the embedded type equipment.

Description

technical field [0001] The invention relates to the communication field, in particular to an embedded system and a virtual screen realization method thereof. Background technique [0002] With the development of technology and the improvement of living standards, more and more electronic products such as industrial control, medical treatment, communication, and consumption are increasingly intelligent, and embedded systems with microprocessors as the core are increasingly widely used. Management of embedded devices has also become a focus of embedded applications. [0003] Among the various solutions for monitoring and managing embedded devices, a simple protocol method for remote login is proposed. This method pulls the display content of the embedded device on the embedded device to the background program interface through the serial port. It shows that the user can perform input operations on the background program interface, and these operations will be automatically se...
