Method for implementing remote debarkation of embedded equipment by cascade interface

Abstract

The invention discloses a method for realizing remote login of an embedded device by using a serial port. The method includes the following steps: the background of the network management obtains the configuration information of the remote embedded device and the current interface display data of the output device through the serial port, and according to the received To configure information and display data, the network management background generates a simulated human-computer interaction interface of the remote embedded device on the interface of the client area; the network management background sends the control commands generated by its input device to the remote embedded device, and the remote embedded device The control command performs buffer processing, and at the same time sends the current interface display data back to the network management background; according to the buffer processing control command, the remote embedded device generates the corresponding current interface display data in the display buffer set in its memory and sends it to output device. By adopting the invention, the remote real-time online diagnosis and maintenance of the remote embedded device can be realized through the serial port, thereby reducing the maintenance cost of the device manufacturer.

Description

technical field [0001] The invention relates to a method for monitoring and managing remote equipment in the communication field, in particular to a method for realizing remote login of an embedded device by using a serial port, so as to monitor and manage the embedded device. 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 becoming increasingly intelligent, and embedded systems with microprocessors as the core are increasingly widely used. Management of intelligent equipment has also become a focus of embedded applications. Users can configure, manage and monitor it through the intelligent interface provided by the device, such as serial port, parallel port, Ethernet port, etc. The high-speed Ethernet interface based on the complex TCP / IP (Transmission Control Protocol / Internet Protocol) protocol is the...
