Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0021] Such as figure 1 As shown in FIG. 1 , a channel self-adapting device for UART serial port expansion includes a UART master interface module, a self-adapting logic operation module and a UART slave expansion interface module. The external end of the UART main interface module is connected to the control panel serial port of the device or the computer serial port (the control panel of the device and the computer are called hosts here), and the internal connection end of the UART main interface module is connected to one end of the self-adaptive logic operation module. The other end of the self-adaptive logic operation module is connected with the internal terminal of the UART slave expansi...

Abstract

The invention discloses a path self-adapting device and method for UART serial port expansion. Between the UART main interface and the UART slave expansion interface module, an adaptation logic operation module is added, and the adaptation logic operation module can intelligently measure, distinguish and Execute the occupation and release operation of the UART uplink channel, realize the self-adaptation operation of the independent channel with high switching efficiency, fast speed, short idle time and complete intelligent automation, without affecting the communication speed, convenient for UART serial port expansion, and has a good application prospect.

Description

technical field [0001] The invention relates to a path self-adapting device and method for UART serial port expansion, belonging to the technical field of serial port communication. Background technique [0002] Universal Asynchronous Receiver / Transmitter (UART) is a universal serial data bus that can realize full-duplex transmission. Reference ground) can enable two devices to communicate, simple, reliable, and easy to use, so it has been widely used. [0003] At present, a device contains multiple slave devices, and each device communicates with the control panel of the device using a UART serial port. It is necessary to expand the UART serial port of the control panel. After expansion, channel gating will be brought Switching methods, the general method is: 1. After the host issues a channel switching command, the serial port channel adapter device executes this operation; 2. After the serial port channel adapter device executes the switching command of other devices, it...
