AI Technical Summary

Technical Problem

In existing communication systems, multiple UART ports occupy a large amount of board space and require multiple serial cables to obtain CPU status information, which is inconvenient for operation and maintenance.

Method used

Using programmable logic chips and signal processors, UART signals are converted into level signals through first-level and second-level selectors and output through a serial port connector, reducing the number of UART ports and enabling remote communication.

Benefits of technology

It simplifies the operation and maintenance process, requiring only one serial port interface to monitor the status of multiple CPUs, saving board space and supporting remote communication.

Abstract

The application discloses a communication switching system, method and device and a readable storage medium, and relates to the field of electronic systems.The communication switching system comprises a programmable chip and a CPU.Compared with the previous mode of arranging multiple UART sockets in a control terminal, the communication switching system of the application is arranged in the form of a programmable chip, so that the UART signal is converted into a corresponding level signal through a two-stage selector, the level signal is sent to the control terminal through the two-stage selector, and the control terminal can directly monitor the state of the CPU and communicate through the level signal and the CPU state corresponding to the pre-set level signal, so that only one serial communication interface is needed instead of multiple UART interfaces, and operation and maintenance are more convenient.
